The WHO quality of life assessment instrument:Investigating its discriminant ability for psychiatric outpatients

This study scrutinizes the ability of the WHO quality of life assessment instrument (WHOQOL-100) to discriminate (1) between psychiatric outpatients and the general population, and (2) between subgroups of psychiatric outpatients. A sample of Dutch adult psychiatric outpatients (N=410) completed the WHOQOL-100. In addition, DSM-IV Axis-I and Axis-II diagnoses were obtained. Compared with the general population, psychiatric outpatients scored significantly lower on all aspects of self-reported quality of life (QOL). Within the group of outpatients, participants with DSM-IV diagnoses had lower scores than those without. Participants with diagnoses on both Axis-I and Axis-II of DSM-IV (comorbidity) had the lowest self-reported QOL. It is concluded that in psychiatric outpatients, outcome scores of self-reported QOL were negatively related to presence and degree of psychopathology. The WHOQOL-100 has good discriminant ability for psychiatric outpatients

This study examines the relationship between personality and quality of life (QOL) in psychiatric outpatients (N=495). Personality was conceptualized using two-dimensional models, respectively, the five-factor model (FFM) and Cloninger's seven-factor model. The WHOQOL-100 was used for assessing QOL. Neuroticism and Harm Avoidance had negative correlations with QOL, whereas Extraversion, Conscientiousness and Self-Directedness correlated positively with QOL. A considerable part of the QOL variance was explained by personality; Cloninger's character factors were superior to the FFM domains. Although not fully comparable, in general our findings are in accordance with earlier studies. Therefore, paying attention to personality and temperament is recommended in future diagnostic procedures, treatment policies, and program evaluations
