Validation of the Greek translation of the multicultural quality of life index (MQLI-gr)

Abstract

Abstract Background The aim of the current study was to examine the internal structure and convergent and discriminant validity of the Multicultural Quality of Life Index (MQLI) in a Greek sample of community-dwelling adults in a major Greek city. Methods The authors developed a Greek version of the Multicultural Quality of Life Index (MQLI-Gr). It was translated following cross-cultural adaptation procedures for self-report measures and administered to community members (N = 884). Participants completed a brief demographic survey, the MQLI-Gr, and the Depression Anxiety Stress Scales (DASS-42). Results The MQLI-Gr is brief, easy to use, and demonstrates strong internal consistency (Cronbach alpha = .90). In terms of internal structure there were mixed results. In terms of discriminant validity, statistically significant differences in mean MQLI-Gr scores were observed between two groups: those with none-mild symptoms versus those with severe symptoms of depression, anxiety, and stress (p < .05). The MQLI-Gr was also able to discriminate among groups assumed to vary on quality of life; marital status, income, and employment. In terms of convergent validity, results were in the expected direction, with participants reporting high levels of depression, anxiety, and stress, also reporting lower quality of life on the MQLI-Gr (p < .001). Conclusion Consistent with other translations, the MQLI-Gr demonstrated feasibility, strong internal consistency, and good convergent and discriminant validity. This is the first step in the development of a psychometrically sound measure to assess quality of life in a community-dwelling population in Greece. With the addition of further validation studies, this measure will be a useful tool for assessing the quality of life in the Greek community.
