Psychometric properties of the WHOQOL-BREF in a population of older adults in prison: measuring quality of life in a carceral setting

This study aims to examine the reliability, validity and factor structure of the WHOQOL-BREF.Secondary data from a large-scale study with older adults (age 45+) incarcerated in a Midwestern state were used (N = 499). Floor and ceiling effects were examined, as was the reliability of the measure (Cronbach's alpha). The structural validity of a four-factor and second-order four-factor model of the WHOQOL-BREF was examined using confirmatory factor analysis. Model data fit was examined using chi-square, standardized root mean square residual, comparative fit indices, Akaike information criterion and the Bayesian Information Criterion. Pearson product-moment correlation coefficients were also used to assess validity.Results indicate adequate construct validity and reliability for the WHOQOL-BREF using the current sample. Model-data fit indexes also reveal adequate structure of the measure relative to other older adult samples. Non-random data and item exclusion are noteworthy limits, and future researchers are encouraged to co-conceptualize and operationalize life quality with older adults who are incarcerated.To the best of the authors’ knowledge, this is the first study to explore the psychometric properties of the WHOQOL-BREF among older adults incarcerated in prison.
