Factor structure of quality of life: The Lehman interview

This study of 67 chronically mentally ill outpatients with psychotic disorders examined subjective quality of life scores from Lehman's Quality of Life (QOL) interview. Factor analyses identified 'Affiliative' and 'Instrumental' dimensions which accounted for 67% of the variance in subjective satisfaction ratings. The results suggest a model in which instrumental and affiliative needs comprise significant portions of subjective life satisfaction and that global QOL satisfaction is related more to instrumental than affiliative needs. These findings further clarify the concept of life satisfaction in this population of severely mentally ill individuals and suggest modifications in how quality of life information is evaluated.
