Conspiracy mentality among informal caregivers as a risk factor for caregiver burden, mental health, perceived loneliness and social isolation during the COVID-19 pandemic: findings of a representative online study from Germany

PURPOSE: This study aims to analyze if and how conspiracy mentality is associated with mental health, burden and perceived social isolation and loneliness of informal caregivers of older individuals with care needs.

METHODS: A quantitative, cross-sectional study was conducted. Participants had to be at least 40 years of age and were drawn randomly from the German online panel forsa.omninet and questioned between the 4th and 19th of March 2021. A sample of 489 informal caregivers (relatives and non-relatives supporting individuals aged ≥ 60 years) was questioned. Conspiracy mentality, depressive symptoms, loneliness and social exclusion were measured with validated instruments (e.g., The Conspiracy Mentality Questionnaire). Questions referred to the last three months prior to assessment. Multiple linear regression analyses, adjusted for sociodemographic, economic and health factors and indicators of the pandemic, were conducted.

RESULTS: Findings indicate a significant positive association between conspiracy mentality and caregiver burden, loneliness, social exclusion, and depressive symptoms. No gender differences were found for any outcome.

CONCLUSIONS: The results indicate that conspiracy mentality could be a risk factor for mental health, perceived social isolation and loneliness, and contribute to increased caregiver burden among informal caregivers of older care recipients during the COVID-19 pandemic. Accordingly, informal caregivers could benefit from actions focused on reducing conspiracy mentality during a health crisis, which could improve psychosocial health and wellbeing in this vulnerable group.
