Social Phobia: Diagnosis, Assessment, and Treatment

A systematic review and meta-analysis of longitudinal cohort studies comparing mental health before versus during the COVID-19 pandemic in 2020

Lockdowns to control the spread of the coronavirus disease 2019 (COVID-19) have had profound effects on everyday life worldwide, but their effect on mental health remains unclear because available meta-analyses and reviews rely mostly on cross-sectional studies. We conducted a rapid review and meta-analysis of longitudinal studies and natural experiments investigating the relationship between COVID-19 lockdowns and mental health. A total of 25 studies involving 72 004 participants and 58 effect sizes were analyzed. Using a random effects model, we found that lockdowns had small effects on mental health symptoms, g = 0.17, s.e. = 0.05, 95% CI (0.06-0.24), p = 0.001, but the effects on positive psychological functioning, g = -0.12, s.e. = 0.11, 95% CI (-0.33 to 0.09), p = 0.27, were not significant. Multivariate analysis of effect sizes revealed significant and relatively small effect sizes for anxiety and depression, while those for social support, loneliness, general distress, negative affect, and suicide risk were not significant. The results indicated substantial heterogeneity among studies, but meta-regression analyses found no significant moderation effects for mean age, gender, continent, COVID-19 death rate, days of lockdown, publication status or study design. The psychological impact of COVID-19 lockdowns is small in magnitude and highly heterogeneous, suggesting that lockdowns do not have uniformly detrimental effects on mental health and that most people are psychologically resilient to their effects.

The psychological impact of COVID-19 pandemic lockdowns: a review and meta-analysis of longitudinal studies and natural experiments.

Students' mental health problems before, during, and after COVID-19 lockdown in Italy.

Orthorexia Nervosa is characterized by specific behaviors frequently related to other psychopathological conditions, such as Obsessive–Compulsive Disorder (OCD) and Eating Disorders (EDs). Whereas ON can mainly be described as an excessive concern regarding healthy food, the study’s principal aim was to investigate if ON could be considered a condition related and differentiated from worry, other than OCD, EDs, perfectionism, anxiety, and depression. To achieve these aims, 302 individuals from the general population were enrolled and were divided into two groups named “High EHQ” and “Low EHQ”, based on their Eating Habits Questionnaire’s score (EHQ-21). Correlations of ON with EDs and non-adaptive perfectionism constructs emerged independently from Obsessive-Compulsive (OC) symptoms, and the same pattern was observed when comparing the High and the Low EHQ groups. The two groups also differ in the worry anxiety and depression constructs and are not affected by OC symptoms removal. Our results confirm a relationship between ON with the typical ED, perfectionistic, anxious, and depressive symptomatology, mainly when the OC features are controlled; moreover, worry constructs could be considered characteristic of the ON phenomenology. This study does not entirely exclude the relationship with obsessive and compulsive characteristics, which could be associated with or serve as a mediator of the orthorexic behavior. Future research could explore the potential mediating or collateral role of OC symptoms. Level III, evidence obtained from well-designed cohort or case–control analytic studies.

Orthorexia Nervosa: over concern or obsession about healthy food?

The lockdown due to coronavirus pandemic may exacerbate depressive symptoms, experts argue. Here we report that students, a high-risk category for mental disorders, report on average worse depressive symptoms than six months before isolation. The prospective data reported herein should alert clinician of a possible aggravation as well as new-onsets of depressive symptoms in students.

COVID-19 and depressive symptoms in students before and during lockdown

Orthorexia Nervosa (ON) is characterised by excessive attention to a dietary regimen perceived as healthy. A critical factor in the distinction between ON and other eating disorders (EDs) is the dichotomy of quality-versus-quantity of food intake. We investigated whether specific types of diet or dieting frequency are associated with orthorexic features, explored the overlap between ON and EDs symptoms, and examined which constructs are predictive of ON after 6 months.A total of 1075 students (75.1% female, mean age 20.9) completed a set of questionnaires assessing Orthorexia, Eating Disorders, Obsessions and Compulsions, Anxiety and Depression; 358 individuals (79.9 female, mean age 20.9) agreed to participate in the study and completed the same questionnaires after 6 months. Different regression models were defined to investigate our hypothesis.Findings suggest that ON is associated with the number and type of diets followed over a lifetime. Moreover, participants with EDs, body dissatisfaction, or a dysfunctional idea of thinness are more likely to report a greater degree of ON features. After 6 months, the best predictors of ON characteristics are the same ON characteristics assessed at the first administration, with a significant role in the ideal of thinness.ON is more frequent in individuals with a previous diagnosis of EDs and in individuals who followed a restrictive diet or a vegan/vegetarian one; the number of lifetime diets, beliefs, and behaviors related to the ideals of thinness or body dissatisfaction is common features of ON. Moreover, considering that having ON features in the past is the best ON predictor in the present, we can presume that ON is a construct stable over time.Level IV: Evidence obtained from multiple time series analysis such as case studies. (NB: Dramatic results in uncontrolled trials might also be regarded as this type of evidence).

Orthorexia nervosa and dieting in a non-clinical sample: a prospective study

Orthorexia Nervosa (ON) is a construct characterized by behaviors, emotions, and beliefs on eating healthy food and excessive attention to diet; moreover, dieting has been considered a risk factor in ON symptoms development. The principal aim of this study was to investigate the differences in clinical and non-clinical groups most at risk of ON. Aspects that could be associated with ON (Eating Disorders [EDs], obsessive-compulsive symptomatology, perfectionistic traits, anxiety, depression, Body Mass Index [BMI]) were investigated in all groups. The sample consisted of 329 adults belonging to four different groups. Three were on a diet: Anorexia/Bulimia Nervosa group (N = 90), Obesity/Binge Eating Disorder group (N = 54), Diet group (N = 91). The Control group consisted of people who were not following a diet (N = 94). Participants completed several self-administered questionnaires (EHQ-21, EDI-3, OCI-R, MPS, BAI, BDI-II) to assess ON-related features in different groups. Analyses highlighted higher orthorexic tendencies in Anorexia/Bulimia Nervosa, Obesity/BED, and Diet groups than in the Control group. Moreover, results have shown that in the AN/BN group, eating disorders symptomatology and a lower BMI were related to ON and that in Obesity/Binge Eating Disorder and Diet groups, perfectionism traits are associated with ON. Individuals who pursue a diet share some similarities with those who have an eating disorder regarding emotions, behaviors, and problems associated with orthorexic tendencies. Moreover, perfectionistic traits seem to predispose to higher ON tendencies. In general, these results confirm the ON as an aspect of the main eating disorders category.
