Translation and Validation of the De Jong Gierveld Loneliness Scale Among Older Migrants Living in the Netherlands.

Abstract

We validate a translated version of the De Jong Gierveld Loneliness Scale (DJGLS) for use among older migrants from Turkish and Moroccan descent and validate the original Dutch version of the same scale for Surinamese migrants in the Netherlands. The data were derived from a population-based cross-sectional study among community-dwelling individuals aged 55 and older. In addition to translating the DJGLS for these ethnic groups, several statistical analyses were performed to assess the scale's reliability and validity. The DJGLS proved to be internally consistent and to have adequate convergent validity among all ethnic groups. Latent structure analysis confirmed the two latent factors (emotional and social subscales) in all groups, but also showed that fit was not optimal in most groups. Known groups validity was observed using functional limitations and subjective health as grouping variables. The results provide sufficient support for use of the translated version of the 11-item DJGLS among Turkish and Moroccan older migrants and use of the Dutch version for Surinamese older migrants as a reliable and valid measure of loneliness. Fit of latent structural models varied between good and poor. Further research is needed to investigate ethnic differences in levels and determinants of loneliness.
