Negative and supportive social interactions and quality of life among persons diagnosed with severe mental illness.

This study examined the relative importance of negative and supportive social interactions in predicting different aspects of quality of life (QOL) in a sample of persons diagnosed with severe mental illness (n = 104). Controlling for other variables that might explain such a relationship, we found that negative social interactions were significantly related to lower QOL in three subjective domains, while supportive social interactions were related to higher QOL in four objective domains and one subjective domain. We found negative social interactions that are stigmatizing to be particularly important in predicting QOL; additional analyses suggested that perceived stigma partially mediated the relationship between negative social interactions and QOL. We discuss the implications of the present findings for the study of the link between social relationships and QOL among persons with mental illness.
