This research focused on the intricacies of mental health within the psychotherapist community, a domain currently understudied. A recent study suggests a better overall mental health profile for Austrian psychotherapists compared to the general population. However, a substantial proportion of psychotherapists still exhibited scores beyond the cut-off for clinically significant mental disorders, potentially undermining the efficacy of patient outcomes. A cross-sectional study was conducted between April to June 2023, enrolling a cohort of 502 Austrian psychotherapists (79.7% female; mean age: 53.4 ± 9.26 years). The analysis leveraged indicators for symptoms of depression (PHQ-2), anxiety (GAD-2), insomnia (ISI-2), stress (PSS-4), and overall well-being (WHO-5). Key correlations were revealed using multivariable logistic regressions incorporating sociodemographic, work-related, and health behavior variables. Mental health symptoms in psychotherapists were associated with lower income, lesser physical activity, employment in outpatient facilities, less experience in the field, and a smaller patient load. Notably, physical activity emerged as a significant protective component, underscoring regular exercise as a vital self-care routine for psychotherapists. Adequate income also presented as a crucial contributor to mental health stability. These findings augment our understanding of the complex dynamics influencing psychotherapists' mental health, potentially enhancing their well-being and optimizing professional output.
