title: The Spanish version of the quality of life index: presentation and validation.
abstract: Latino or Spanish-speaking individuals constitute a substantial and growing population in the United States, in addition to their general presence, with cultural variations, throughout Latin America and the Iberian Peninsula. To respond to the needs of this population, a Spanish version of the Quality of Life Index (QLI-Sp) was developed. The QLI, in its various language versions, is a concise instrument for comprehensive, culture-informed, and self-rated assessment of health-rated quality of life. It is composed of 10 dimensions collated from the international literature, including aspects ranging from physical well-being to spiritual fulfillment, as well as a global perception of quality of life. Each item is to be rated on a 10-point line by Latino subjects according to their culture-informed understanding of that concept. The study samples included 60 Latino psychiatric patients (20 outpatient, 20 inpatient, and 20 partial hospitalization) and 20 Latino actively working hospital professionals. Mean time of completion was 2.4 minutes among health professionals and 3.6 minutes among patients. The vast majority of respondents (72% of patients and 1000% of professionals) judged the instrument as easy to use. The test-retest reliability correlation coefficient of the QLI-Sp mean score was .89. The discriminant validity of the QLI-Sp was documented by the highly significant difference obtained between the mean scores of the two samples selected to represent quite different levels of quality of life.
