Alcohol Use Disorder Criteria Exhibit Different Comorbidity Patterns.

Abstract: BACKGROUND AND AIMS Alcohol use disorder is comorbid with numerous other forms of psychopathology, including externalizing disorders (e.g., conduct disorder) and, to a lesser extent, internalizing conditions (e.g., depression, anxiety). Much of the time, overlap among alcohol use disorder and other conditions is explored at the disorder-level, assuming that criteria are co-equal indicators of other psychopathology even though alcohol use disorder criteria span numerous varied domains. Emerging evidence suggests that there are symptom clusters within the construct of alcohol use disorder that relate differentially with important external criteria, including psychopathology and allied personality traits (e.g., impulsivity, novelty seeking). The present study mapped individual alcohol use disorder criteria onto internalizing and externalizing dimensions. Design and participants We used multivariate and factor analytic modeling and data from 2 large nationally representative samples of past year drinkers (ns = 25,604; 19,454). SETTING USA MEASUREMENTS: Psychopathology was assessed using the Alcohol Use Disorder and Associated Disabilities Interview Schedule, yielding alcohol use disorder criteria, internalizing diagnoses (i.e., major depressive disorder, dysthymia, social anxiety disorder, generalized anxiety disorder, specific phobia, agoraphobia, and panic disorder), and externalizing diagnoses and symptoms (i.e., antisocial personality disorder, conduct disorder, and 3 impulsivity items drawn from borderline personality disorder criteria). Alcohol consumption was assessed in terms of past-year drinking frequency, usual amount of alcohol consumed on drinking days, binge drinking frequency, intoxication frequency, and maximum number of drinks in a 24-hour period. FINDINGS Four different patterns emerged. First, several alcohol use disorder criteria were relatively weakly associated with externalizing and internalizing. Second, withdrawal was associated with internalizing, but this association was not specific to distress. Third, there was a general lack of specificity between alcohol use disorder criteria and narrower forms of internalizing, despite what might be predicted by modern models of addiction. Fourth, recurrent use in hazardous situations reflected higher degrees of externalizing and lower internalizing liability. CONCLUSIONS Different symptom combinations appear to yield differential expressions of alcohol use disorder that are disorder-specific, or reflect broader tendencies toward externalizing, internalizing, or both.

COVID-19 Emotional and Mental Impact on Cancer Patients Receiving Radiotherapy: An Interpretation of Potential Explaining Descriptors

Abstract: Background: Significant changes in the accessibility and viability of health services have been observed during the COVID-19 period, particularly in vulnerable groups such as cancer patients. In this study, we described the impact of radical practice and perceived changes on cancer patients’ mental well-being and investigated potential outcome descriptors. Methods: Generalized anxiety disorder assessment (GAD-7), patient health (PHQ-9), and World Health Organization-five well-being index (WHO-5) questionnaires were used to assess anxiety, depression, and mental well-being. Information on participants, disease baseline information, and COVID-19-related questions were collected, and related explanatory variables were included for statistical analysis. Results: The mean score values for anxiety, depression, and mental well-being were 4.7 ± 5.53, 4.9 ± 6.42, and 72.2 ± 18.53, respectively. GAD-7 and PHQ-9 scores were statistically associated (p < 0.001), while high values of GAD-7 and PHQ-9 questionnaires were related to low values of WHO-5 (p < 0.001).Using the GAD-7 scale, 16.2% of participants were classified as having mild anxiety (GAD-7 score: 5–9).Mild to more severe anxiety was significantly associated with a history of mental health conditions (p = 0.01, OR = 3.74, 95% CI [1.372–10.21]), and stage category (stage III/IV vs. I/II, p = 0.01, OR = 3.83, 95% CI [1.38–10.64]. From the participants, 36.2% were considered to have depression (PHQ-9 score ≥ 5). Depression was related with older patients (p = 0.05, OR = 1.63, 95% CI [1.16–2.3]), those with previous mental health conditions (p = 0.03, OR = 14.24, 95% CI [2.47–81.84]), those concerned about the COVID-19 impact on their cancer treatment (p = 0.027, OR = 0.19, 95% CI [0.045–0.82]) or those who felt that COVID-19 pandemic has affected mental health (p = 0.013, OR = 3.56, 95% CI [1.30–9.72]). Additionally, most participants (86.7%) had a good well-being score (WHO-5 score ≥ 50). Mental well-being seemed more reduced among stage I–III patients than stage IV patients (p = 0.014, OR = 0.12, 95% CI [0.023–0.65]). Conclusion: There is a necessity for comprehensive cancer care improvement. These patients’ main concern related to cancer therapy, yet the group of patients who were mentally affected by the pandemic should be identified and supported.

Anxiety Screening: Evidence Report and Systematic Review for the US Preventive Services Task Force.

Abstract: Importance Anxiety is commonly seen in primary care and associated with substantial burden. Objective To review the benefits and harms of screening and treatment for anxiety and the accuracy of instruments to detect anxiety among primary care patients. Data Sources MEDLINE, PsychINFO, Cochrane library through September 7, 2022; references of existing reviews; ongoing surveillance for relevant literature through November 25, 2022. Study Selection English-language original studies and systematic reviews of screening or treatment compared with control conditions and test accuracy studies of a priori-selected screening instruments were included. Two investigators independently reviewed abstracts and full-text articles for inclusion. Two investigators independently rated study quality. Data Extraction and Synthesis One investigator abstracted data; a second checked accuracy. Meta-analysis results were included from existing systematic reviews where available; meta-analyses were conducted on original research when evidence was sufficient. Main Outcomes and Measures Anxiety and depression outcomes; global quality of life and functioning; sensitivity and specificity of screening tools. Results Of the 59 publications included, 40 were original studies (N = 275 489) and 19 were systematic reviews (including ≈483 studies [N≈81 507]). Two screening studies found no benefit for screening for anxiety. Among test accuracy studies, only the Generalized Anxiety Disorder (GAD) GAD-2 and GAD-7 screening instruments were evaluated by more than 1 study. Both screening instruments had adequate accuracy for detecting generalized anxiety disorder (eg, across 3 studies the GAD-7 at a cutoff of 10 had a pooled sensitivity of 0.79 [95% CI, 0.69 to 0.94] and specificity of 0.89 [95% CI, 0.83 to 0.94]). Evidence was limited for other instruments and other anxiety disorders. A large body of evidence supported the benefit of treatment for anxiety. For example, psychological interventions were associated with a small pooled standardized mean difference of -0.41 in anxiety symptom severity in primary care patients with anxiety (95% CI, -0.58 to -0.23]; 10 RCTs [n = 2075]; I2 = 40.2%); larger effects were found in general adult populations. Conclusions and Relevance Evidence was insufficient to draw conclusions about the benefits or harms of anxiety screening programs. However, clear evidence exists that treatment for anxiety is beneficial, and more limited evidence indicates that some anxiety screening instruments have acceptable accuracy to detect generalized anxiety disorder.

A Multicenter Double-Blind, Placebo-Controlled Trial of Escitalopram in Children and Adolescents with Generalized Anxiety Disorder.

Abstract: Objective: Generalized anxiety disorder (GAD) in children and adolescents is associated with substantial morbidity and increases the risk of future psychopathology. However, relatively few psychopharmacologic studies have examined treatments for GAD in pediatric populations, especially in prepubertal youth. Methods: Children and adolescents aged 7-17 years of age with a primary diagnosis of GAD were treated with flexibly dosed escitalopram (10-20 mg daily, n = 138) or placebo (n = 137) for 8 weeks. Efficacy measures included the Pediatric Anxiety Rating Scale (PARS) for GAD, Clinical Global Impression of Severity (CGI-S) scale, Children's Global Assessment Scale (CGAS); safety measures included the Columbia-Suicide Severity Rating Scale (C-SSRS) as well as adverse events (AEs), vital signs, and electrocardiographic and laboratory monitoring. Results: Escitalopram was superior to placebo in reducing anxiety symptoms of GAD, as seen in the difference in mean change from baseline to week 8 on the PARS severity for GAD score (least squares mean difference = -1.42; p = 0.028). Functional improvement, as reflected by CGAS score, was numerically greater in escitalopram-treated patients compared with those receiving placebo (p = 0.286), and discontinuation owing to AEs did not differ between the two groups. Vital signs, weight, laboratory, and electrocardiographic results were consistent with previous pediatric studies of escitalopram. Conclusions: Escitalopram reduced anxiety symptoms and was well tolerated in pediatric patients with GAD. These findings confirm earlier reports of escitalopram efficacy in adolescents aged 12-17 years and extend the safety and tolerability data to children with GAD aged 7-11 years. ClinicalTrials.gov Identifier: NCT03924323.

The Impact of COVID-19 Infection and Characterization of Long COVID in Adolescents With Anxiety Disorders: A Prospective Longitudinal Study

Abstract: While the coronavirus disease 2019 (COVID-19) pandemic has profoundly impacted pediatric mental health, the impact of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection on youth with anxiety disorders has not been prospectively examined. Further, there are limited prospective data on post-acute sequelae COVID-19, including symptoms that constitute the long COVID neuropsychiatric syndrome. In December 2019, we began a longitudinal study of adolescents aged 12-17 years with DSM-5 primary anxiety disorders treated with either duloxetine or escitalopram. Assessments included all items from the Generalized Anxiety Disorder-7 (GAD-7) and Quick Inventory of Depressive Symptomatology (QIDS) scales at each week and a weekly clinician-rated Clinical Global Impressions-Severity (CGI-S) scale. We examined the longitudinal course of anxiety, including following laboratory-confirmed SARS-CoV-2 infection in affected adolescents. This prospective study of the longitudinal impact of COVID-19 in pediatric anxiety disorders reveals that COVID-19 is associated with worsening anxiety symptoms and a disquieting 33% worsening in syndromic severity. Further, these data raise the possibility that, in anxious youth, COVID-19 is associated with a surfeit of neuropsychiatric symptoms.

Mental health and social support among Royal Canadian Mounted Police cadets

Abstract: Introduction Certain populations, such as public safety personnel (PSP), experience frequent exposures to potentially psychologically traumatic events and other occupational stressors, increasing their risk for mental health challenges. Social support has been evidenced as a protective factor for mental health. However, research examining perceived social support and its associations with symptoms related to mental disorders among PSP recruits is limited. Methods RCMP cadets (n = 765, 72% male) completed self-report surveys assessing: sociodemographic information, social support, and symptoms related to posttraumatic stress disorder, major depressive disorder, generalized anxiety disorder, social anxiety disorder, panic disorder, and alcohol use disorder. Results The results indicated statistically significant associations between higher social support and decreased odds of positive screens for generalized anxiety disorder, social anxiety disorder, and panic disorder (i.e., significant Adjusted Odds Ratios = 0.90 to 0.95). Discussion Cadets’ perceived levels of social support are comparable to the Canadian general population and higher than serving RCMP. Social support appears to offer a protective element against anxiety-related disorders among participating cadets. Reductions in perceived levels of social support may be a function of RCMP service. Factors contributing to decreased levels of perceived social support should be considered.

Chinese version of Dominic Interactive – A self-report video game for assessing mental health in young children

Abstract: Objectives Assess the validity of the Chinese version of the Dominic Interactive (DI), a 91-item, video-based diagnostic screening instrument for children that assesses four internalized disorders (phobias, separation anxiety disorder, generalized anxiety disorder, and major depressive disorder) and three externalized disorders (attention-deficit/hyperactivity disorder, conduct disorder, oppositional defiant disorder). Methods (1) Compare DI-generated “probable” or “possible” diagnoses to diagnoses based on the Development and Well-Being Assessment (DAWBA) instrument in 113 psychiatric outpatients and 20 community controls. (2) Administer DI to 1,479 children from elementary schools in Tianjin. Results In the validation sample, DI with DAWBA concordance was much greater for internalized disorders (mean Kappa = 0.56) than for externalized disorders (mean kappa = 0.11). The positive predictive value of DI diagnoses ranged from 0.96 (generalized anxiety disorder) to 25% (oppositional defiant disorder) and negative from 0.81 to 0.96. Using “probable” cuts provides better results. In the survey, prevalence of probable DI disorders ranged from 1.0% (conduct disorder) to 13.1% (phobias). Internal consistency of all DI items was excellent (Cronbach alpha = 0.93) and that of the seven subscales ranged from 0.64 (phobias) to 0.87 (major depressive disorder). In multilevel SEM analyses, SRMR (Standardized root mean square residual) or each of the seven diagnoses was below 0.08 and each coefficient of determination was below 0.60. Conclusion The Chinese DI is a convenient method of screening common mental disorders in Chinese children mainly for internalized disorders, which are the most prevalent diagnoses in that population. However its high negative predictive values for externalized could be used for screening.

Psychometric properties of the generalized anxiety disorder-7 (GAD-7) in a sample of workers

Abstract: Objective To evaluate the psychometric properties of the GAD-7 by obtaining evidence of internal structure (dimensionality, precision and differential functioning of items) and association with external variables. Methods A total of 2,219 protocols from three different studies conducted with Puerto Rican employees that administered the GAD-7 were selected for the current study. Item response theory modeling was used to assess internal structure, and linear association with external variables. Results The items were adapted to a graduated response model, with high similarity in the discrimination and location parameters, as well as in the precision at the level of the items and in the total score. No violation of local independence and differential item functioning was detected. The association with convergent (work-related rumination) and divergent (work engagement, sex, and age) variables were theoretically consistent. Conclusion The GAD-7 is a psychometrically robust tool for detecting individual variability in symptoms of anxiety in workers.

The Gut-Brain Axis and the Microbiome in Anxiety Disorders, Post-Traumatic Stress Disorder and Obsessive-Compulsive Disorder

Abstract: A large body of research supports the role of stress in several psychiatric disorders in which anxiety is a prominent symptom. Other research has indicated that the gut microbiome-immune system brain axis is involved in a large number of disorders and that this axis is affected by various stressors. The focus of the current review is on the following stress-related disorders: generalized anxiety disorder, panic disorder, social anxiety disorder, post-traumatic stress disorder and obsessive-compulsive disorder. Descriptions of systems interacting in the gut-brain axis, microbiome-derived molecules and of pro- and prebiotics are given. Preclinical and clinical studies on the relationship of the gut microbiome to the psychiatric disorders mentioned above are reviewed. Many studies support the role of the gut microbiome in the production of symptoms in these disorders and suggest the potential for pro- and prebiotics for their treatment, but there are also contradictory findings and concerns about the limitations of some of the research that has been done. Matters to be considered in future research include longer-term studies with factors such as sex of the subjects, drug use, comorbidity, ethnicity/race, environmental effects, diet, and exercise taken into account; appropriate compositions of pro- and prebiotics; the translatability of studies on animal models to clinical situations; and the effects on the gut microbiome of drugs currently used to treat these disorders. Despite these challenges, this is a very active area of research that holds promise for more effective, precision treatment of these stress.

Reduced vmPFC-insula functional connectivity in generalized anxiety disorder: a Bayesian confirmation study

Abstract: Abstract Differences in the correlated activity of networked brain regions have been reported in individuals with generalized anxiety disorder (GAD) but an overreliance on null-hypothesis significance testing (NHST) limits the identification of disorder-relevant relationships. In this preregistered study, we applied both a Bayesian statistical framework and NHST to the analysis of resting-state fMRI scans from females with GAD and matched healthy comparison females. Eleven a-priori hypotheses about functional connectivity (FC) were evaluated using Bayesian (multilevel model) and frequentist ( t -test) inference. Reduced FC between the ventromedial prefrontal cortex (vmPFC) and the posterior-mid insula (PMI) was confirmed by both statistical approaches and was associated with anxiety sensitivity. FC between the vmPFC-anterior insula, the amygdala-PMI, and the amygdala-dorsolateral prefrontal cortex (dlPFC) region pairs did not survive multiple comparison correction using the frequentist approach. However, the Bayesian model provided evidence for these region pairs having decreased FC in the GAD group. Leveraging Bayesian modeling, we demonstrate decreased FC of the vmPFC, insula, amygdala, and dlPFC in females with GAD. Exploiting the Bayesian framework revealed FC abnormalities between region pairs excluded by the frequentist analysis and other previously undescribed regions in GAD, demonstrating the value of applying this approach to resting-state FC data in clinical investigations.

Prevalence and effects of sleep-disordered breathing on middle-aged patients with sedative-free generalized anxiety disorder: A prospective case-control study

Abstract: Objective Generalized anxiety disorder (GAD) and sleep-disordered breathing (SDB) share similar symptoms, such as poor sleep quality, irritability, and poor concentration during daily activities. This study aims to investigate the proportion of undiagnosed SDB and its impacts on anxiety severity and autonomic function in newly diagnosed, sedative-free GAD patients. Methods This prospective case-control study included newly diagnosed GAD patients and control participants with matched age, sex, and body mass index (BMI) in Taiwan. All participants completed questionnaires for sleep and mood symptoms and a resting 5-min heart rate variability (HRV) examination during enrollment. The participants also used a home sleep apnea test to detect SDB. An oxygen desaturation index (ODI) ≥ 5 was considered indicative of SDB. Results In total, 56 controls and 47 newly diagnosed GAD participants (mean age 55.31 ± 12.36 years, mean BMI 23.41 ± 3.42 kg/m2) were included. There was no significant difference in the proportion of undiagnosed SDB in the control and sedative-free GAD groups (46.43 vs. 51.06%). Sedative-free GAD patients with SDB scored significantly higher on Beck Anxiety Inventory (23.83 ± 11.54) than those without SDB (16.52 ± 10.61) (p < 0.001). Both control and sedative-free GAD groups with SDB had worse global autonomic function than the control group without SDB, as evidenced by the HRV results (p < 0.05 for all). Conclusion Average age 55 years and mean BMI 23 kg/m2 patients with GAD and matched controls had an undiagnosed SDB prevalence of approximately 50%. SDB correlated with worsening anxiety severity and reduced cardiac autonomic function. Moreover, age and BMI were considered major risk factors for predicting undiagnosed SDB.

Dissociable salience and default mode network modulation in generalized anxiety disorder: a connectome-wide association study.

Abstract: Generalized anxiety disorder (GAD) is a common anxiety disorder experiencing psychological and somatic symptoms. Here, we explored the link between the individual variation in functional connectome and anxiety symptoms, especially psychological and somatic dimensions, which remains unknown. In a sample of 118 GAD patients and matched 85 healthy controls (HCs), we used multivariate distance-based matrix regression to examine the relationship between resting-state functional connectivity (FC) and the severity of anxiety. We identified multiple hub regions belonging to salience network (SN) and default mode network (DMN) where dysconnectivity associated with anxiety symptoms (P < 0.05, false discovery rate [FDR]-corrected). Follow-up analyses revealed that patient's psychological anxiety was dominated by the hyper-connectivity within DMN, whereas the somatic anxiety could be modulated by hyper-connectivity within SN and DMN. Moreover, hypo-connectivity between SN and DMN were related to both anxiety dimensions. Furthermore, GAD patients showed significant network-level FC changes compared with HCs (P < 0.01, FDR-corrected). Finally, we found the connectivity of DMN could predict the individual psychological symptom in an independent GAD sample. Together, our work emphasizes the potential dissociable roles of SN and DMN in the pathophysiology of GAD's anxiety symptoms, which may be crucial in providing a promising neuroimaging biomarker for novel personalized treatment strategies.

Somatic masks of anxiety disorder and therapy opportunities

Abstract: Anxiety disorders are often found in the practice of doctors of all specialties and cause difficulties in making a diagnosis, which is associated with a variety of clinical manifestations. Traditionally, anxiety disorders are considered within the framework of neuroses and include conditions such as adjustment disorders, generalized anxiety disorder, and a number of somatoform disorders. The article gives a distinction between the concepts of “anxiety” and “anxiety disorders”. It should be noted that anxiety disorders cannot be considered in isolation from the concept of “stress”. Chronic stressful situations exacerbate or contribute to the development of somatic pathology, including neurological. The somatic manifestations of anxiety disorders are diverse and affect all organs and systems: cardialgia, tachycardia, heart rhythm disturbances, hyperventilation syndrome, abdominalgia, irritable bowel syndrome, neurodermatitis, etc. It is important to timely and correctly diagnose generalized anxiety disorder, which occurs both in isolation (borderline psychiatry) and in patients with various somatic pathologies and its main manifestation is generalized, persistent anxiety, not caused and not limited by any external circumstances, accompanied by autonomic, motor manifestations. Diagnostic criteria for generalized anxiety disorder are also presented in the article.To identify and objectify symptoms of anxiety in practice, it is advisable to use special questionnaires: the Hospital Anxiety and Depression Scale, the Hamilton Anxiety Scale, the Spielberger-Khanin Situational and Personal Anxiety Scale. The article presents a clinical case of a patient with anxiety disorder. The clinical picture and tactics of managing the patient are analyzed. The addition of etifoxine to therapy made it possible to stop the clinical manifestations of anxiety disorder in a short time.

Predictors and prevalence of stress, anxiety, depression, and PTSD among university students during the second wave of the COVID-19 pandemic in Turkey

Abstract: This study aimed to find the prevalence of stress, anxiety, depression, and PTSD; differences according to demographic variables; and predictors of mental health problems during the second wave of the coronavirus disease (COVID-19) pandemic in Turkey. Differences in exposure to COVID-19 during the first and second waves of the pandemic among students were compared. A total of 754 students from seven universities in different parts of Turkey participated in the survey between November and December 2020. Perceived Stress Scale (PSS-10), Generalized Anxiety Disorder (GAD-7), Patient Health Questionnaire (PHQ-9), Checklist-Civilian Version (PCL-C) scale measuring posttraumatic stress disorder (PTSD), and Satisfaction with Life Scale (SWLS) were used to measure the mental well-being of students. Descriptive statistics, one-way ANOVA, correlations, and multinomial logistic regression methods were used to analyze the data. The prevalence of high stress, high generalized anxiety (GAD-7 ≥ 10), high depression symptoms (PHQ-9 ≥ 10), and high PTSD in the total sample were 84.2, 36.2, 55.0, and 61.2%, respectively. High perceived stress, moderate generalized anxiety disorder, mild depression symptoms, high severity PTSD, and moderate satisfaction were found among students in Turkey. Religiosity and spirituality have significant negative correlations with anxiety, depression, and PTSD. Religiosity level, gender, relationship status, year of study, physical activity, symptoms of coronavirus, death of a close relative, job loss, and economic status are significant parameters for predicting psychological problems of students in Turkey.

Differences in Center for Epidemiologic Studies Depression Scale, Generalized Anxiety Disorder-7 and Kessler Screening Scale for Psychological Distress Scores between Smartphone Version versus Paper Version Administration: Evidence of Equivalence

Abstract: The use of electronic patient-reported outcomes has increased recently, and smartphones offer distinct advantages over other devices. However, previous systematic reviews have not investigated the reliability of the Center for Epidemiologic Studies Depression Scale (CES-D), Generalized Anxiety Disorder-7 (GAD-7), and Kessler Screening Scale for Psychological Distress (K6) when used with smartphones, and this has not been fully explored. This study aimed to evaluate the equivalence of the paper and smartphone versions of the CES-D, GAD-7, and K6, which were compared following a randomized crossover design method in 100 adults in Gunma, Japan. Participants responded to the paper and smartphone versions at 1-week intervals. The equivalence of paper and smartphone versions was evaluated using the intraclass correlation coefficient (ICCagreement). The mean participant age was 19.86 years (SD = 1.08, 23% male). The ICCagreements for the paper and smartphone versions of the CES-D, GAD-7, and K6 were 0.76 (95% confidence interval [CI] 0.66–0.83), 0.68 (95% CI 0.59–0.77), and 0.83 (95% CI 0.75–0.88), respectively. Thus, the CES-D and K6 scales are appropriate for use in a smartphone version, which could be applied to clinical and research settings in which the paper or smartphone versions could be used as needed.

Generalized anxiety disorder in Berlin school children after the third COVID-19 wave in Germany: a cohort study between June and September 2021

Abstract: Abstract Background During the COVID-19 pandemic, children and adolescents worldwide have disproportionally been affected in their psychological health and wellbeing. We conducted a cohort study among German school children, aiming at assessing levels of general anxiety disorder (GAD) and identifying associated factors in the second pandemic year. Methods A cohort of 660 students from 24 Berlin schools was recruited to fill in questionnaires including the GAD-7 tool on anxiety symptoms at three time points between June and September 2021. To adjust for non-random attrition, we applied inverse probability weighting. We describe reported GAD levels stratified by time point, sex, and school type and report odds ratios from univariate logistic regression. Results In total, 551 participants (83%) filled in at least one questionnaire at any time point. At the first time point in June 2021, 25% of the children and adolescents reported anxiety symptoms with a GAD-7 score ≥ 5, decreasing to 16% in August 2021 directly after the summer holidays and rising again to 26% in September 2021. The majority of reported anxiety levels belonged to the least severe category. Being female, attending secondary school, coming from a household with lower education or with lower income level, and being vaccinated against COVID-19 were significantly linked with reporting anxiety symptoms. Preceding COVID-19 infection and anxiety were negatively associated. Conclusion Overall, anxiety in school children was lower in mid-2021 than in the first pandemic year, but still double compared to pre-pandemic data. Reporting of anxiety symptoms during the second pandemic year was especially high in females and in secondary school students. Policy makers should pay additional attention to the mental health status of school children, even as the pandemic situation might stabilize.

Maternal mental health during COVID-19 pandemic outbreak: A cross-sectional comparative study

Abstract: Background As COVID-19 spread in several countries, social distancing measures was implemented around the world, affecting the quality of lives for millions of people. The impact was more pronounced on vulnerable populations such as pregnant women, who are at even more risk due to their suppressed immune system. Moreover, mental health disorders are more common among pregnant women compared to non-pregnant. This study aims to assess the influence of social isolation measures due to the COVID-19 pandemic on the mental health of women in their third trimester and postpartum. Material and methods This is a cross-sectional survey-based study conducted in Khalid University Hospital, Riyadh, Saudi Arabia, between the months of April to May 2021, to explore depression and anxiety levels in females who gave birth during the COVID-19 pandemic. In addition to background demographic data, the survey included Patient Health Questionnaire-9 (PHQ-9) and Generalized Anxiety Disorder Scale-7 (GAD-7) were utilized to detect symptoms of depression and anxiety, respectively. Results A total of 283 women were included in this study, almost half of them were ante-natal (n-141) and the rest were post-natal (n = 124). 62.3% were in the age groups of 25–35 years. Based on the PHQ-9 scoring, 65% of the study sample had depression (ranging from mild to severe). Moreover, based on GAD-7 scoring, 49.1% had anxiety (ranging from mild to severe). No association was found between PHQ-9 and GAD-7 scores and different sociodemographic and obstetric factors. Additionally, the mean scores of women infected with COVID-19 vs. women who has never been diagnosed with COVID-19 were closely comparable. Conclusions We reported a high prevalence of depression and anxiety among pregnant women during COVID-19 pandemic. Policymakers and health care providers are advised to implement targeted preventive measures for pregnant women to improve mental health in times of epidemics.

Prevalence and risk factors of COVID-19-related generalized anxiety disorder among the general public in China: a cross-sectional study

Abstract: Objective This study aimed to estimate the prevalence of generalized anxiety disorder in China during the coronavirus disease 2019 (COVID-19) pandemic and identify its associated factors. Methods A cross-sectional study was conducted among the general population in China from March 16 to April 2, 2020. The participants were recruited using stratified random sampling. Data on demographic characteristics and COVID-19 related factors were obtained using self-administered questionnaires. The anxiety score was measured based on the Chinese version of the Generalized Anxiety Disorder 7-item Scale (GAD-7). Results The study comprised 10,824 participants, of which 37.69% had symptoms of anxiety. The risk factors for anxiety symptoms included poor self-reported health (OR = 1.672, p < 0.001), chronic diseases (OR = 1.389, p < 0.001), and quarantine (OR = 1.365, p < 0.001), while participants’ perceptions that COVID-19 would be controlled was a protective factor (OR = 0.774, p < 0.001). The interactions between quarantine and self-reported health (p < 0.001), as well as between perceptions of COVID-19 and self-reported health (p < 0.001) were found to have a significant effect on GAD-7 scores. Conclusions Self-reported health status, chronic diseases, quarantine, and perceptions of COVID-19 were significantly associated with GAD-7 scores, indicating that mental health interventions are urgently needed during pandemics, especially for high-risk groups.

The Anxiolytic and Antidepressant Effects of Transcranial Magnetic Stimulation in Patients With Anxious Depression.

Abstract: Objective: To determine the extent that treatment with transcranial magnetic stimulation (TMS) in diverse clinical settings has anxiolytic and antidepressant effects in patients with major depressive disorder (MDD) and moderate-to-severe anxiety symptoms and to contrast anxious and nonanxious depression subgroups in antidepressant effects. Methods: Within the NeuroStar Advanced Therapy System Clinical Outcomes Registry, 1,820 patients were identified with a diagnosis of MDD (using ICD-9, ICD-10, or DSM-IV) who completed the Patient Health Questionnaire-9 (PHQ-9) and Global Anxiety Disoder-7 scale (GAD-7) at baseline and following at least 1 TMS treatment between May 2016 and January 2021. Anxious depression was defined as a baseline GAD-7 score of 10 or greater (n = 1,514) and nonanxious depression by GAD-7 scores below this threshold (n = 306). Intent-to-treat and Completer samples were defined for patients treated with any TMS protocol and for the subgroup treated only with high-frequency left dorsolateral prefrontal cortex stimulation. Results: Patients with anxious depression showed clinically meaningful anxiolytic and antidepressant effects, averaging approximately 50% or greater reductions in both GAD-7 and PHQ-9 scores following TMS in all samples. The anxious and nonanxious depression groups had equivalent absolute improvement in PHQ-9 scores (P values ≥ .29). However, the anxious group had higher scores both at baseline and following TMS resulting in significantly lower categorical rates of response (P values < .02) and remission (P values < .001) in depressive symptoms. Among those with anxious depression, the change in anxiety and depression symptoms strongly covaried (r1512 = 0.75, P < .001). Conclusions: Routine TMS delivered in diverse clinical settings results in marked anxiolytic and antidepressant effects in patients with anxious depression. The extent of improvement in anxiety and depression symptoms strongly covaries.

Testing domain knowledge and risk of bias of a large-scale general artificial intelligence model in mental health

Abstract: Background With a rapidly expanding gap between the need for and availability of mental health care, artificial intelligence (AI) presents a promising, scalable solution to mental health assessment and treatment. Given the novelty and inscrutable nature of such systems, exploratory measures aimed at understanding domain knowledge and potential biases of such systems are necessary for ongoing translational development and future deployment in high-stakes healthcare settings. Methods We investigated the domain knowledge and demographic bias of a generative, AI model using contrived clinical vignettes with systematically varied demographic features. We used balanced accuracy (BAC) to quantify the model’s performance. We used generalized linear mixed-effects models to quantify the relationship between demographic factors and model interpretation. Findings We found variable model performance across diagnoses; attention deficit hyperactivity disorder, posttraumatic stress disorder, alcohol use disorder, narcissistic personality disorder, binge eating disorder, and generalized anxiety disorder showed high BAC (0.70 ≤ BAC ≤ 0.82); bipolar disorder, bulimia nervosa, barbiturate use disorder, conduct disorder, somatic symptom disorder, benzodiazepine use disorder, LSD use disorder, histrionic personality disorder, and functional neurological symptom disorder showed low BAC (BAC ≤ 0.59). Interpretation Our findings demonstrate initial promise in the domain knowledge of a large AI model, with performance variability perhaps due to the more salient hallmark symptoms, narrower differential diagnosis, and higher prevalence of some disorders. We found limited evidence of model demographic bias, although we do observe some gender and racial differences in model outcomes mirroring real-world differential prevalence estimates.

Interconnectivity of fear of progression and generalized anxiety – Network analysis among a sample of hematological cancer survivors

Abstract: Abstract Purpose Fear of cancer progression and recurrence (FoP) and generalized anxiety disorder (GAD) are syndromes commonly seen in cancer patients. This study applied network analysis to investigate how symptoms of both concepts are interconnected. Methods We used cross-sectional data from hematological cancer survivors. A regularized Gaussian graphical model including symptoms of FoP (FoP-Q) and GAD (GAD-7) was estimated. We investigated (i) the overall network structure and (ii) tested on pre-selected items whether both syndromes could be differentiated based on their worry content (cancer related vs. generalized). For this purpose, we applied a metric named bridge expected influence (BEI). Lower values mean that an item is only weakly connected with the items of the other syndrome, which can be an indication of its distinctive characteristic. Results Out of 2001 eligible hematological cancer survivors, 922 (46%) participated. The mean age was 64 years and 53% were female. The mean partial correlation within each construct (GAD: r = .13; FoP: r = .07) was greater than between both (r = .01). BEI values among items supposed to discriminate between the constructs (e.g., worry about many things within GAD and fear not to endure treatment within FoP) were among the smallest so our assumptions were confirmed. Conclusions Our findings based on the network analysis support the hypothesis that FoP and GAD are different concepts within oncology. Our exploratory data needs to be validated in future longitudinal studies.

Clinical Markers of Panic and Generalized Anxiety Disorder: Overlapping Symptoms, Different Course and Outcome

Abstract: Generalized Anxiety Disorder (GAD) and Panic Disorder (PD) share underlying neurobiological mechanisms and several clinical features which, with medical comorbidities, may increase misdiagnosis and delay proper treatment. The aim of the study was to evaluate the association between clinical/socio-demographic markers and GAD/PD diagnosis. Outpatients (N = 290) with PD or GAD were identified in mental health services in Monza and Milan (Italy). Descriptive analyses and a binary logistic regression model were performed. Post-onset psychiatric (p = 0.05) and medical (p = 0.02) multiple co-morbidities were associated with GAD; treatment with selective serotonin reuptake inhibitors (SSRIs) was associated with PD, while GAD diagnosis was associated with treatment with atypical antipsychotics or GABAergic drugs (p = 0.03), as well as psychodynamic psychotherapy (p < 0.01). Discontinuation of the last pharmacological treatment was associated with GAD diagnosis rather than the PD one (p = 0.02). GAD patients may have a worse prognosis than PD patients because of more frequent multiple co-morbidities, relapses and poorer treatment compliance. The different treatment approaches were consistent with the available literature, while the association between GAD and psychodynamic psychotherapy is an original finding of our study. Further studies on larger samples are necessary to better characterize clinical factors associated with GAD or PD.

Comparing the efficacy of an electronically delivered cognitive behavioural therapy program to a mental health check-in program for generalized anxiety disorder: Protocol for a randomized trial (Preprint)

Abstract: Generalized anxiety disorder (GAD) is a prevalent anxiety disorder with cognitive behavioural therapy (CBT) being the gold-standard treatment. However, it is inaccessible and costly to many as the mental health industry is overwhelmed by the demand for treatment. This means effective, accessible, and time-saving strategies must be developed to combat these problems. Online interventions for mental health disorders are an innovative and promising way to address these barriers. While the electronic delivery of CBT (e-CBT) has already proved productive and scalable for treating anxiety, other less resource-intensive interventions can be innovated. Checking up on one's mental health face to face has been shown to provide similar benefits to patients with anxiety disorders previously, but more research is needed to evaluate the efficacy of online delivery of this intervention. This study will compare the efficacy of e-CBT and a virtual mental health check-in program to treat GAD. These programs will both be delivered through a secure, online, care delivery platform. Participants (n = 100) over 18 years with a confirmed diagnosis of GAD will be randomly allocated to either an e-CBT program or a mental health check-in program over 12 weeks to address their anxiety symptoms. Participants in the e-CBT arm will complete pre-designed modules and homework assignments while receiving personalized feedback and asynchronous interaction with a therapist through the platform. Participants in the mental health check-in arm will be contacted weekly through the online platform’s written chat feature (messaging system). Therapists will ask the participants a series of pre-designed questions that revolve around a different theme each week to prompt conversation. Using clinically validated questionnaires, the efficacy of the e-CBT arm will be compared to the mental health check-in arm. These questionnaires will be completed at baseline, week 6, week 12, and at a 6-month follow-up. The study received ethics approval in April 2021 and participant recruitment began in May 2021. Participant recruitment has been conducted through targeted advertisements and physician referrals. Complete data collection and analysis are expected to conclude by August 2022. Linear and binomial regression (continuous and categorical outcomes respectively) will be conducted. To the research team’s knowledge, this will be the first study, to date, comparing the efficacy of e-CBT with an online mental health check-in program to treat GAD. The findings from this study can help progress the development of more scalable, accessible, and efficacious mental health treatments. clinicaltrials.gov (NCT04754438)
