Psychological distress in community-dwelling individuals living with severe and persistent mental illness

Objectives: To explore psychological distress levels, using the validated Kessler 6 (K6), as well as the relationship between demographics and K6 scores, and incidence of mental health crises in a cohort of community-dwelling people living with severe and persistent mental illness (SPMI). Methods: People living with SPMI taking antipsychotic or mood stabiliser medications were recruited from Australian community pharmacies between September 2020 and Februrary 2021 and completed an electronic survey, including the K6 scale. Pharmacists were interviewed and supplied written reports with details of the consultation when participants obtained 'very high' (> 19/30) K6 scores. Records were reviewed and coded by an independent coder. Multivariate linear regression was used to determine predictors of K6 scores. Results: The median K6 score was 16/30 (IQR = 11,21; range = 6-30). Younger age, unemployment and multimorbid mental health diagnoses were significant predictors of higher K6 scores (p < .01; R-2 = .24). Fifty-nine (39.3%) consumers scored > 19, of which 25/59 (42.4%) were reported to be exhibiting signs of psychological distress and none were experiencing mental health crises. Conclusion: People living with SPMI have high levels of psychological distress as measured by the K6. Further work is needed to understand the prevalence, extent, precipitating factors and impact of psychological distress in people living with SPMI.
