Factorial structure and validity of the Multicultural Quality of Life Index.
OBJECTIVE
To study the internal structure and the convergent and divergent validity of the Multicultural Quality of Life Index (MQLI) in a Spanish sample.


METHODS
The MQLI, along with another quality of life instrument--the World Health Organization Quality of Life, brief version (WHOQOL-BREF)--and the Depression, Anxiety and Stress Scales (DASS-21), was administered to 356 students, 159 people from the general population and 65 psychiatric patients.


RESULTS
The value of Cronbach's a was .90. The confirmatory factor analysis showed a good fit for both the one- and two-factor structures. The overall mean score of the MQLI correlated between .61 and .78 with the domains of the WHOQOL-BREF and between -.55 and -.70 with the DASS-21 scales.


CONCLUSIONS
The MQLI has high internal consistency, can be interpreted in terms of a single factor, and has an adequate convergent validity, although its absolute correlations with depression and with the WHOQOL-BREF were equally high.
