42. Methods for Measuring Quality of Life in Schizophrenia: Does Insight Matter?
Improving quality of life (QoL) is an important treatment target of schizophrenia-spectrum disorders; thus, accurately measuring QoL in this population is crucial. Insight of one’s illness is often impaired in those with schizophrenia and is associated with QoL. Insight may be especially pertinent in the assessment of self-reported QoL as opposed to clinician-rated measures because validity of self-report depends on one’s ability to accurately recount their experience. The current project sought to determine: 1) the role of insight in the assessment of self-reported versus clinician-rated QoL; and 2) if insight affects the relationship between QoL and general functioning. Results revealed weak correlations between domains of the self-reported SF-36 and clinician-rated Heinrich’s QoL Scale. Insight was found to moderate the association between the SF-36 Emotional Well-being and the Heinrich’s Intrapsychic Foundations subscales (b=-0.104, SE=0.047, t(28)=-2.179, p=0.038), but did not significantly moderate relationships in other domains. Clinician-rated QoL was more highly correlated with both social and role functioning than self-reported QoL. Insight did not significantly moderate the relationship between self-reported QoL and global functioning for any domains. Results suggest different methods for assessing QoL may not be targeting equivalent constructs. Implications for the use of QoL assessments in treatment will be discussed.
