Psychometric Properties of the Cambridge Depersonalization Scale in Puerto Rico

摘要

Depersonalization experiences have been studied in the United States and Europe, but there is a dearth of investigations with Latino populations. In the current study we examined the psychometric properties of the Spanish version of the Cambridge Depersonalization Scale (CDS) in 300 adult individuals from the community and compared the results with those reported previously with non-Latino clinical populations. Discrepant findings have been reported with respect to the factor structure of the CDS. We performed exploratory and confirmatory factor analyses on the CDS items and compared our results with published analyses on other populations. Results revealed that the psychometric properties of the CDS, such as reliability, seem adequate, although the factor structure of the CDS seems to be inconsistent across studies. We selected a 4-factor solution that was most parsimonious and best fit our data. Furthermore, we obtained a moderate, statistically significant relationship (r = .64, p = .001) between the CDS and the Dissociative Experiences Scale. Our results, utilizing a nonclinical sample of Puerto Rican adults, suggest that depersonalization experiences can be reliably measured in a Latino and Spanish-speaking population.
