Promotion of good mental health, prevention, and early intervention before/at the onset of mental disorders improve outcomes. However, the range and peak ages at onset for mental disorders are not fully established.

Background: The mental health impact of the COVID-19 crisis may differ from previously studied stressful events in terms of psychological reactions, specific risk factors, and symptom severity across geographic regions worldwide. 

Objective: To assess the impact of COVID-19 on a wide range of mental health symptoms, to identify relevant risk factors, to identify the effect of COVID-19 country impact on mental health, and to evaluate regional differences in psychological responses to COVID-19 compared to other stressful events.

Background: The use of remotely delivered early intervention after trauma may prevent and/or reduce symptoms of post-traumatic stress. Our research group evaluated a novel three-week therapist-guided internet-delivered intervention based on prolonged exposure (Condensed Internet-Delivered Prolonged Exposure; CIPE) in a pilot trial. The results indicated that the intervention was feasible, acceptable and reduced symptoms of post-traumatic stress at post-intervention compared to a waiting-list condition.

Bereavement may precipitate significant mental health problems. Prolonged grief disorder (PGD) is included in section 2 of the forthcoming DSM-5 text-revision (DSM-5-TR). Research using earlier criteria of disordered grief showed that bereaved people may have distinct symptom patterns—including high, low, and comorbid symptomatology.
