Validación de la escala Seguridad en el Sistema Familiar (SIFS) en dos muestras españolas de adolescentes y jóvenes residentes con su familia e institucionalizados

Abstract

The psychometric properties of the Security in the Family System scale (SIFS) (Davies & Forman, 2005) are analyzed in this paper. SIFS measures children’s perceived security in the family system grounded on Emotional Security theory (Cummings & Davies, 2010). Particpants were 845 Spanish adolescents and youth, 180 of whom were institutionalized (mean age 15.67 years) while 665 lived with their families (mean age 14.9 years). Confirmatory factor analyses and configural, metric,scalar and strict invariance analyses were performed. Results showed that the instrument is adequate to evaluate Spanish adolescents’ and youth’s security in the family whether they live with their families or they are institutionalized. The three dimensions predicted by the theory were identified (security, preoccupation and disengagement) with a good internal consistency and comparable punctuations.
