Quality of life in people with severe mental illness. Reliability and validity of the Manchester Short Assessment of Quality of Life (MANSA).
The Manchester Short Assessment of Quality of Life (MANSA) is a short interview, which has received a recent interest in research investigating quality of life in people with mental illness. In the present study, the Swedish version of MANSA is examined with regard to reliability, in terms of internal consistency and construct validity. Ninety-two persons with severe mental illness were interviewed regarding quality of life, social network, psychosocial functioning, psychiatric symptoms, needs for care, empowerment and experiences of stigma. Internal consistency was adequate (alpha = 0.81). Positive correlations were found between MANSA and social network, empowerment and psychosocial functioning, and negative correlations with psychopathology, number of needs for care, perceived devaluation and discrimination, and rejection experiences. Social network, psychosocial functioning and beliefs of devaluation and discrimination altogether explained 67% of the variance in quality of life. The Swedish version of MANSA showed a satisfactory reliability in terms of internal consistency. The construct of validity of the scale was satisfactory insofar as associations with validation measures were of considerable magnitude and in expected directions.
