Introduction There are few published empirical data on the effects of COVID‐19 on mental health, and until now, there is no large international study. Material and methods During the COVID-19 pandemic, an online questionnaire gathered data from 55,589 participants from 40 countries (64.85% females aged 35.80 ± 13.61; 34.05% males aged 34.90±13.29 and 1.10% other aged 31.64±13.15). Distress and probable depression were identified with the use of a previously developed cut-off and algorithm respectively. Statistical analysis Descriptive statistics were calculated. Chi-square tests, multiple forward stepwise linear regression analyses and Factorial Analysis of Variance (ANOVA) tested relations among variables. Results Probable depression was detected in 17.80% and distress in 16.71%. A significant percentage reported a deterioration in mental state, family dynamics and everyday lifestyle. Persons with a history of mental disorders had higher rates of current depression (31.82% vs. 13.07%). At least half of participants were accepting (at least to a moderate degree) a non-bizarre conspiracy. The highest Relative Risk (RR) to develop depression was associated with history of Bipolar disorder and self-harm/attempts (RR = 5.88). Suicidality was not increased in persons without a history of any mental disorder. Based on these results a model was developed. Conclusions The final model revealed multiple vulnerabilities and an interplay leading from simple anxiety to probable depression and suicidality through distress. This could be of practical utility since many of these factors are modifiable. Future research and interventions should specifically focus on them.

The Pattern study was conducted to provide longitudinal observational data for individual patients with persistent symptoms of schizophrenia. Pattern is an international, multicenter, non-interventional, prospective cohort study of schizophrenia outpatients who were not considered to be in recovery. In the longitudinal phase reported herein, patients were assessed over 1 year using different clinical rating scales. Patient management followed routine local clinical practice. Primary outcome was disease state, defined by the Positive and Negative Syndrome Scale (PANSS), Negative Symptom Factor Score (NSFS), Positive Symptom Factor Score (PSFS), and Personal and Social Performance (PSP) Scale. In total, 1344 protocol-compliant patients (70.9% male) were included. Patients showed a high stability in disease state between consecutive study visits. Persistent negative persistent symptoms and symptomatic remission were the most prevalent and stable disease states. Patients in relapse generally transitioned to negative persistent symptoms or to symptomatic remission. PANSS, PSP, and quality of life ratings remained relatively stable. Relapses occurred in 10% of patients; probability of relapse was associated with younger age, extra-pyramidal symptoms, and more antipsychotic medications. Despite treatment, schizophrenia symptoms tend to remain stable over time, without overall improvement. One of the greatest challenges in schizophrenia is attainment of full symptom remission.

Agomelatine was shown to be effective on anhedonia, depression, and anxiety in subjects with major depression. The pragmatic design of the study reflects real-world clinical practice providing interesting insights into routine care management.
