Research on the sex lives of people with severe mental illness (SMI) most often focuses on dysfunction and the side-effects of medication. We wished to determine how people with SMI experience sex and assess satisfaction with it in a broader evaluation of quality of life. Data was gathered using mixed methods, including a reliable psychometric quality of life instrument, and in-depth interviews. Sex life showed the lowest rating of all quality of life domains, with men indicating lower satisfaction in this area than women. Low satisfaction also correlated with lower scores on the total quality of life index. Sexuality and intimate relations were generally experienced as out of reach or something of secondary importance that had to be controlled, according to many of those suffering from SMI. Programs such as patient disorder-specific or partner assisted interventions, to increase the possibility of sustaining a sex life might need to be added to existing recommendations for people with SMI living in a community.
