This study explored the factors contributing to relapse of mental health care users (MHCUs) treated for substance-induced psychotic disorder in a public psychiatric hospital in Gauteng, South Africa. A qualitative, explorative, descriptive and contextual research design was followed. The study was conducted at the outpatient department of the hospital. Participants were selected purposefully from MHCUs visiting the outpatient department for follow-up. Ten semi-structured interviews were used to collect data until data saturation occurred. The transcribed interviews and field notes were analysed using Tesch's method of qualitative data analysis. The researcher and an independent coder reached consensus on the categories, sub-categories and themes. Trustworthiness was ensured through application of the strategies of dependability, transferability, conformability, credibility and authenticity.
The findings explicated the factors contributing to relapse of MHCUs treated for substance-induced psychotic disorder in a psychiatric hospital. These factors included psychological, physical and social factors. Recommendations were provided for psychiatric nurses in terms of therapeutic programme planning and involvement of the community and family in the management of MHCUs treated for substance-induced psychotic disorder.
