Abstract
Studies reported a strong impact on mental health during the first wave of the COVID-19 pandemic in March–June, 2020. In this study, we investigated the impact of the pandemic on mental health in general and on schizoptypal traits specifically in general population samples of the UK (N 1st timepoint=239, N 2nd timepoint= 126) and Germany (N 1st timepoint= 543, N 2nd timepoint=401) over two timepoints, April/May and September/October 2020. We were able to show that whereas general psychological symptoms (global symptom index, GSI) and percentage of responders above clinical cut-off for further psychological investigation declined from the first to the second timepoint in both countries, schizotypy scores (Schizotypal Personality Questionnaire) were increased at the second timepoint. We investigated potential predictors, using regression models. For schizotypy, we detected a doubling or more of the estimated impact from the first to the second timepoint, including stronger perceived loneliness, increased use of drugs, stronger financial burden, and decreased regular exercise and sleep. These effects predicted GSI, however with a lower increase of impact from the first to the second timepoint. We furthermore found that living in the UK was a predictor for higher schizotypal scores or GSI. However, the results are highly comparable between the two countries. In conclusion, this study shows that while the general psychological impact decreases, potentially showing a normative response to an exceptional situation; schizotypy scores increase, revealing a stronger impact of loneliness, drug use, and financial burden. This development might create an increased risk for developing psychosis in some individuals. The development of the general psychological and schizotypy scores over time requires further attention and investigation.This publication has 49 references indexed in Scilit:
