ABSTRACT=The aim of the present study was to confirm the original factor structure of the Multicultural Quality of Life Index (MQLI) and analyze its psychometric properties in a sample of caregivers of people with borderline personality disorder (BPD). Methods: The MQLI was administered to 233 relatives of people with BPD. Participants completed the MQLI, the Depression, Anxiety and Stress Scale (DASS-21), and the Connor-Davidson Resilience Scale (CD-RISC). Results: Factor analysis of the relatives indicated that the MQLI generated a one-factor solution. The MQLI showed good internal consistency,  = .91 (95% CI [.90, .93]) and correlated significantly and positively with the CD-RISC (rs = .576) and negatively with the DASS-21 (r = -.583), respectively. Conclusion: Consistent with other studies, the MQLI demonstrated feasibility, strong internal consistency, and good convergent and discriminant validity, which means it is a psychometrically robust measure for the assessment of quality of life in relatives of people with BPD. Along with other validation studies, this measure will be a useful tool for assessing quality of life in relatives of people with mental disorders.
