Análisis de la Escala de Soledad de De Jong Gierveld mediante el modelo de Rasch

Abstract

This study examines the psychometric properties of the Spanish adaptation of the De Jong Gierveld Loneliness Scale by means of the Rasch model. Participants were 614 Spanish community-dwelling older adults (60-96 years). Convergent/divergent validity was examined by correlating the scale with both the PANAS scale and a satisfaction with life scale. Results showed that our data fit the model and that average item reliability were high (0.99), but average person reliability was low (0.69). Factorial analysis confirmed a unidimensional structure. Some items had a significant DIF for sex and living arrangements. The scale demonstrated moderate convergent/discriminant validity. These results should be taken into account for a revision of the instrument.
