Psychometric Properties of the Spirituality Index in Costa Rican Older Adults

Abstract

 Objective. The aim of this study was to show evidence of the Spirituality Index for the elderly in Costa Rica. Method. 282 elders participated (M = 64 years, SD = 7.55) and data was collected in the Great Metropolitan Area between 2015 and 2016. Results. A Confirmatory Factor Analysis showed validity evidence indicating a one-dimensional structure (χ2 = 21.03, gl = 9, p = .001; CFI = .997; TLI = .994; RMSEA = .094 [.041 - .148], SRMR = .022). Reliability, as indicated by Cronbach's alpha and McDonald’s omega, demonstrated adequate internal consistency (.91). Validity evidence was also found with Temporal Life Satisfaction (r = .263, p = .001) and Psychological Well-Being (r = .173, p < .01). The results suggest that the Spirituality Index for the elderly is a satisfactory indicator to measure spirituality in Costa Rican elders.
