TL;DR: It is confirmed that almost one third of the general population is affected by mental disorders and inform about subsets in the population who are particularly affected.
Abstract: This paper provides up to date prevalence estimates of mental disorders in Germany derived from a national survey (German Health Interview and Examination Survey for Adults, Mental Health Module [DEGS1-MH]). A nationally representative sample (N = 5318) of the adult (18–79) population was examined by clinically trained interviewers with a modified version of the Composite International Diagnostic Interview (DEGS-CIDI) to assess symptoms, syndromes and diagnoses according to DSM-IV-TR (25 diagnoses covered). Of the participants 27.7% met criteria for at least one mental disorder during the past 12 months, among them 44% with more than one disorder and 22% with three or more diagnoses. Most frequent were anxiety (15.3%), mood (9.3%) and substance use disorders (5.7%). Overall rates for mental disorders were substantially higher in women (33% versus 22% in men), younger age group (18–34: 37% versus 20% in age group 65–79), when living without a partner (37% versus 26% with partnership) or with low (38%) versus high socio-economic status (22%). High degree of urbanization (> 500,000 inhabitants versus < 20,000) was associated with elevated rates of psychotic (5.2% versus 2.5%) and mood disorders (13.9% versus 7.8%). The findings confirm that almost one third of the general population is affected by mental disorders and inform about subsets in the population who are particularly affected.

TL;DR: This epidemiological picture is an important benchmark for identifying persons at greater risk of suffering from psychological distress and the results are useful for tailoring psychological interventions targeting the post-traumatic nature of the distress.
Abstract: The uncontrolled spread of the coronavirus disease 2019 (COVID-19) has called for unprecedented measures, to the extent that the Italian government has imposed a quarantine on the entire country. Quarantine has a huge impact and can cause considerable psychological strain. The present study aims to establish the prevalence of psychiatric symptoms and identify risk and protective factors for psychological distress in the general population. An online survey was administered from 18-22 March 2020 to 2766 participants. Multivariate ordinal logistic regression models were constructed to examine the associations between sociodemographic variables; personality traits; depression, anxiety, and stress. Female gender, negative affect, and detachment were associated with higher levels of depression, anxiety, and stress. Having an acquaintance infected was associated with increased levels of both depression and stress, whereas a history of stressful situations and medical problems was associated with higher levels of depression and anxiety. Finally, those with a family member infected and young person who had to work outside their domicile presented higher levels of anxiety and stress, respectively. This epidemiological picture is an important benchmark for identifying persons at greater risk of suffering from psychological distress and the results are useful for tailoring psychological interventions targeting the post-traumatic nature of the distress.

TL;DR: The German health interview and examination survey for adults with the mental health module (DEGS1-MH) is the successor to the last survey of mental disorders in the general German population 15 years ago and reports the basic findings on the 12-month prevalence ofmental disorders, associated disabilities and self-reported healthcare utilization.
Abstract: Die „Studie zur Gesundheit Erwachsener in Deutschland“ (DEGS1) und ihr Zusatzmodul „Psychische Gesundheit“ (DEGS1-MH) erlauben erstmals seit dem 15 Jahre zuruckliegenden Bundesgesundheitssurvey (BGS98) aktuelle Abschatzungen zu Morbiditat, Einschrankungsprofilen und Inanspruchnahmeverhalten der deutschen Erwachsenen. Es werden die wichtigsten Ergebnisse zu Pravalenzen psychischer Storungen, zu damit assoziierten Beeintrachtigungen sowie zu Kontaktraten mit Gesundheitsdiensten berichtet. Der Studie liegt eine bevolkerungsreprasentative Erwachsenenstichprobe (18–79 Jahre, n = 5317) zugrunde, die uberwiegend personlich mit ausfuhrlichen klinischen Interviews (Composite International Diagnostic Interview; CIDI) untersucht wurde. Die 12-Monats-Pravalenz psychischer Storungen betragt insgesamt 27,7 %, wobei grose Unterschiede in verschiedenen Gruppen (z. B. Geschlecht, Alter, sozialer Status) zu verzeichnen sind. Psychische Storungen stellten sich als besonders beeintrachtigend heraus (erhohte Zahl an Einschrankungstagen). Weniger als die Halfte der Betroffenen berichtet, aktuell wegen psychischer Probleme in Behandlung zu stehen (10–40 % in Abhangigkeit von der Anzahl der Diagnosen). Psychische Storungen sind haufig. Die im Vergleich zu Personen ohne aktuelle psychische Diagnose deutlich erhohte Rate an Beeintrachtigungstagen signalisiert neben dem individuellen Leiden der Betroffenen eine grose gesellschaftliche Krankheitslast – auch verglichen mit vielen korperlichen Erkrankungen. Trotz des in Deutschland vergleichsweise gut ausgebauten Versorgungssystems fur psychische Storungen ist Optimierungsbedarf hinsichtlich der Behandlungsrate zu vermuten.

TL;DR: Mental disorders were found to be commonplace with a prevalence level comparable to that found in the 1998 predecessor study but several further adjustments will have to be made for a sound methodological comparison between the studies.
Abstract: Background and objectives The German health interview and examination survey for adults (DEGS1) with the mental health module (DEGS1-MH) is the successor to the last survey of mental disorders in the general German population 15 years ago (GHS-MHS). This paper reports the basic findings on the 12-month prevalence of mental disorders, associated disabilities and self-reported healthcare utilization. Methods A representative national cohort (age range 18-79 years, n = 5,317) was selected and individuals were personally examined (87.5 % face to face and 12.5 % via telephone) by a comprehensive clinical interview using the composite international diagnostic interview (CIDI) questionnaire. Results The overall 12-month prevalence of mental disorders was 27.7 % with substantial differences between subgroups (e.g. sex, age, socioeconomic status). Mental disorders were found to be particularly impairing (elevated number of disability days). Less than 50 % of those affected reported to be in contact with health services due to mental health problems within the last 12 months (range 10-40 % depending on the number of diagnoses). Conclusions Mental disorders were found to be commonplace with a prevalence level comparable to that found in the 1998 predecessor study but several further adjustments will have to be made for a sound methodological comparison between the studies. Apart from individual distress, elevated self-reported disability indicated a high societal disease burden of mental disorders (also in comparison with many somatic diseases). Despite a relatively comprehensive and well developed mental healthcare system in Germany there are still optimisation needs for treatment rates.

TL;DR: This causal taxonomy implies the need for changes in strategies for studying the etiology, psychobiology, prevention, and treatment of psychopathology, and provides a novel framework for understanding the heterogeneity of each first-order dimension.
Abstract: We propose a taxonomy of psychopathology based on patterns of shared causal influences identified in a review of multivariate behavior genetic studies that distinguish genetic and environmental influences that are either common to multiple dimensions of psychopathology or unique to each dimension. At the phenotypic level, first-order dimensions are defined by correlations among symptoms; correlations among first-order dimensions similarly define higher-order domains (e.g., internalizing or externalizing psychopathology). We hypothesize that the robust phenotypic correlations among first-order dimensions reflect a hierarchy of increasingly specific etiologic influences. Some nonspecific etiologic factors increase risk for all first-order dimensions of psychopathology to varying degrees through a general factor of psychopathology. Other nonspecific etiologic factors increase risk only for all first-order dimensions within a more specific higher-order domain. Furthermore, each first-order dimension has its own unique causal influences. Genetic and environmental influences common to family members tend to be nonspecific, whereas environmental influences unique to each individual are more dimension-specific. We posit that these causal influences on psychopathology are moderated by sex and developmental processes. This causal taxonomy also provides a novel framework for understanding the heterogeneity of each first-order dimension: Different persons exhibiting similar symptoms may be influenced by different combinations of etiologic influences from each of the 3 levels of the etiologic hierarchy. Furthermore, we relate the proposed causal taxonomy to transdimensional psychobiological processes, which also impact the heterogeneity of each psychopathology dimension. This causal taxonomy implies the need for changes in strategies for studying the etiology, psychobiology, prevention, and treatment of psychopathology. (PsycINFO Database Record

TL;DR: In addition to making criteria-based diagnoses of depressive disorders, the PHQ-9 is also a reliable and valid measure of depression severity, which makes it a useful clinical and research tool.
Abstract: OBJECTIVE: While considerable attention has focused on improving the detection of depression, assessment of severity is also important in guiding treatment decisions. Therefore, we examined the validity of a brief, new measure of depression severity.

TL;DR: Although mental disorders are widespread, serious cases are concentrated among a relatively small proportion of cases with high comorbidity, as shown in the recently completed US National Comorbidities Survey Replication.
Abstract: Background Little is known about the general population prevalence or severity of DSM-IV mental disorders. Objective To estimate 12-month prevalence, severity, and comorbidity of DSM-IV anxiety, mood, impulse control, and substance disorders in the recently completed US National Comorbidity Survey Replication. Design and Setting Nationally representative face-to-face household survey conducted between February 2001 and April 2003 using a fully structured diagnostic interview, the World Health Organization World Mental Health Survey Initiative version of the Composite International Diagnostic Interview. Participants Nine thousand two hundred eighty-two English-speaking respondents 18 years and older. Main Outcome Measures Twelve-month DSM-IV disorders. Results Twelve-month prevalence estimates were anxiety, 18.1%; mood, 9.5%; impulse control, 8.9%; substance, 3.8%; and any disorder, 26.2%. Of 12-month cases, 22.3% were classified as serious; 37.3%, moderate; and 40.4%, mild. Fifty-five percent carried only a single diagnosis; 22%, 2 diagnoses; and 23%, 3 or more diagnoses. Latent class analysis detected 7 multivariate disorder classes, including 3 highly comorbid classes representing 7% of the population. Conclusion Although mental disorders are widespread, serious cases are concentrated among a relatively small proportion of cases with high comorbidity.
