ABSTRACT=<sec><title>Purpose</title><p>The aim of the present study was to confirm the original factor structure of the <italic>Multicultural Quality of Life Index</italic> (MQLI) and analyze its psychometric properties in a sample of caregivers of people with borderline personality disorder (BPD).</p></sec><sec><title>Methods</title><p>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).</p></sec><sec><title>Results</title><p>Factor analysis of the relatives indicated that the MQLI generated a one-factor solution. The MQLI showed good internal consistency, ϖ = 0.91 [95% CI (0.90, 0.93)] and correlated significantly and positively with the CD-RISC (<italic>r</italic><sub>s</sub> = 0.576) and negatively with the DASS-21 (<italic>r</italic><sub>s</sub> = −0.583).</p></sec><sec><title>Conclusion</title><p>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.</p></sec>
