Abstract
Psicometric properties of the Spanish version of the questionnaire PLC-PECVEC of Profile of Life quality in the Chronically ill. The present paper analize the psicometric properties of the Spanish version of the Profile of Life quality in the Chronically ill "PLC" (in Spanish Perfil de Calidad de Vida en Enfermos Crónicos "PECVEC") , in different ways of application and groups of subjects and compare the results with the reported by original version. The instrument of measurement of Quality Of Life was applied in three diferents groups of 30 subject each one: 1) Civil Personnel (White-Collars); 2) Students of the last course of the School of Medicine and 3) patients affected with Hypertension mild-moderated (Type I-II of the WHO). The questionnaire was filled in by 60 subjects in a self-administered way and with 30 subjects was applied a standardized interview by the doctor or nurse. Several statistic analysis were made: Factor analysis exploratory from each scale (extraction PAF); internal-consistency reliability by coefficient alpha Cronbach; congruent coefficient between factorial solutions of the Spanish sample and another German sample using the original questionnaire and comparisons between the three groups using standardized multivariate and univariate test statistics. Our results show that the Spanish version has comparable properties to those described by the authors in the original version. It was found sufficient internal consistency and construction validity, as well as a good replication of the original factorial structure. The described differences for the groups under study demonstrate the discriminatory capacity of the questionnaire to identify groups of different health conditions.
