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 assessed the impact of the pandemic on mental health in general and on schizotypal traits in two independent general population samples of the United Kingdom (May sample N: 239, October sample N: 126; participation at both timepoints: 21) and in two independent general population samples of Germany (May sample N: 543, October sample N: 401; participation at both timepoints: 100) using online surveys. Whereas general psychological symptoms (global symptom index, GSI) and percentage of responders above clinical cut-off for further psychological investigation were higher in the May sample compared to the October sample, schizotypy scores (Schizotypal Personality Questionnaire) were higher in the October sample. We investigated potential associations, using general linear regression models (GLM). For schizotypy scores, we found that loneliness, use of drugs, and financial burden were more strongly corrected with schizotypy in the October compared to the May sample. We identified similar associations for GSI, as for schizotypy scores, in the May and October samples. We furthermore found that living in the United Kingdom was related to higher schizotypal scores or GSI. However, individual estimates of the GLM are highly comparable between the two countries. In conclusion, this study shows that while the general psychological impact is lower in the October than the May sample, potentially showing a normative response to an exceptional situation; schizotypy scores are higher at the second timepoint, which may be due to a stronger impact of estimates of loneliness, drug use, and financial burden. The ongoing, exceptional circumstances within this pandemic might increase the risk for developing psychosis in some individuals. The development of general psychological symptoms and schizotypy scores over time requires further attention and investigation.
Background:Studies report a strong impact of the COVID-19 pandemic and related stressors on the mental well-being of the general population. In this paper, we investigated whether COVID-19 related concerns and social adversity affected schizotypal traits, anxiety, and depression using structural equational modelling. In mediation analyses, we furthermore explored whether these associations were mediated by healthy (sleep and physical exercise) or unhealthy behaviours (drug and alcohol consumption, excessive media use).Methods:We assessed schizotypy, depression, and anxiety as well as healthy and unhealthy behaviours and a wide range of sociodemographic scores using online surveys from residents of Germany and the United Kingdom over 1 year during the COVID-19 pandemic. Four independent samples were collected (April/May 2020: N=781, September/October 2020: N=498, January/February 2021: N=544, May 2021: N=486). The degree of schizotypy was measured using the Schizotypal Personality Questionnaire (SPQ), anxiety, and depression symptoms were surveyed with the Symptom Checklist (SCL-27), and healthy and unhealthy behaviours were assessed with the Coronavirus Health Impact Survey (CRISIS). Structural equation models were used to consider the influence of COVID-19 related concerns and social adversity on depressive and anxiety-related symptoms and schizotypal traits in relation to certain healthy (sleep and exercise) and unhealthy behaviours (alcohol and drug consumption, excessive media use).Results:The results revealed that COVID-19 related life concerns were significantly associated with schizotypy in the September/October 2020 and May 2021 surveys, with anxiety in the September/October 2020, January/February 2021, and May 2021 surveys, and with depressive symptoms in all surveys. Social adversity significantly affected the expression of schizotypal traits and depressive and anxiety symptoms in all four surveys. Importantly, we found that excessive media consumption (>4 hr per day) fully mediated the relationship between COVID-19 related life concerns and schizotypal traits in the January/February 2021 survey. Furthermore, several of the surveys showed that excessive media consumption was associated with increased depressive and anxiety-related symptoms in people burdened by COVID-19 related life.Conclusions:The ongoing uncertainties of the pandemic and the restrictions on social life have a strong impact on mental well-being and especially the expression of schizotypal traits. The negative impact is further boosted by excessive media consumption, which is especially critical for people with high schizotypal traits.Funding:FK received funding from the European Union’s Horizon 2020 (Grant number 754,462).

Studies reported a strong impact on mental health during the first wave of the COVID 19 pandemic in March to 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 cutoff 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.

The results revealed that COVID-19 related life concerns were significantly associated with schizotypy in the autumn 2020 and spring 2021 surveys, and with anxiety and depressive symptoms in all surveys; and social adversity significantly affected the expression of schizotypal traits in all but the spring 2020 survey, and depressive and anxiety symptoms in all samples. Importantly, we found that excessive media consumption (>4h per day) fully mediated the relationship of COVID-19 related life concerns and schizotypal traits in the winter 2021 survey. Furthermore, several of the surveys showed that excessive media consumption was associated with increased depressive and anxiety- related symptoms in people burdened by COVID-19 related life.The ongoing uncertainties of the pandemic and the restrictions on social life have a strong impact on mental well-being and especially the expression of schizotypal traits. The negative impact is further boosted by excessive media consumption, which is especially critical for people with high schizotypal traits.
