Objective: The purposes of this study were to evaluate the psychometric characteristics and perform a factor analysis of McGill Quality of Life Questionnaire (MQOL) in a sample of recovered depressed patients.
Methods: Present study was a cross sectional research. Data were obtained from a sample of recovered depressed patients. A total of 354 participants (67 males, 287 females) were assessed using the structured clinical interview for DSM-IV disorders (SCID) to ensure their full recovery from their most recent episode of depression. Then, they completed a series of self-report
measures, including the McGill Quality of Life Questionnaire. Confirmatory factor analysis using LISREL-8.54 and Cronbach’s alpha using SPSS-16 were done for analyzing data.
Results: Descriptive statistics for the MQOL were performed, and confirmatory factor analysis was used to assess the fitness of the hypothesized factor structure. The Cronbach α coefficients were calculated for the questionnaire and its each subscale to examine the internal reliability, which was found to be high for the overall questionnaire as well as its each subscale, as α
coefficients ranged from 0.58 (for the physical scale) to 0.88 (for the existential scale).
Conclusion: MQOL can be employed as a tool for assessing quality of life in research and practice in these patients.
