Análisis psicométrico de la Escala de Soledad de UCLA (Versión 3) en una muestra de guardias civiles

Abstract

Loneliness is a complex psychological construct that influences our health through stress and cortisol. In this study we examined psychometrically the Spanish translation of the UCLA Loneliness Scale (Version 3) in a sample of members of the Guardia Civil. The results showed adequate reliability (Cronbach’s alpha .954) for research and evaluation of specific individuals. KMO index was calculated (.969), the Bartlett’s test of sphericity (χ2 (190)=14406.221, ρ<.000) and the determinant of the correlation matrix (.0000018), to examine the appropriateness of analysis factorial. For this analysis we used the polychoric correlation matrix (explains 81.49 % of the total variance), extracting two components through the principal components analysis (PCA) and varimax rotation (10,184 and 1,080). On the other hand, does not seem necessary to delete or revise any items (item-total correlation .486-.804). Consequently, it is concluded that this scale might be valid to study how this variable influences the health of the members of this militarized police force.
