Construction and Psychometric Properties of the Loneliness Scale in Adults

The development procedure and the psychometric properties of the Buenos Aires Loneliness Scale (BALS) are presented. An initial set of 40 items was analyzed by means of the expert judgment method. After that, the 16 selected items were administered to a convenience sample comprised of 509 adult participants (53% of which were female). The Argentine version of the UCLA-LS (University of California Los Angeles Loneliness Scale), the Argentine version of the Balanced Inventory of Socially Desirable Responding, and loneliness self-perception questions were applied in conjunction with the BALS. Exploratory factor analysis showed evidence of unidimensionality, with an adequate internal consistency (alpha=.80, ordinal alpha=.87), and seven items were kept. Correlations with the criterion measures yielded the expected results and no gender-based differential item functioning was found. Conclusions were reached about the adequate psychometric properties of the BALS, the limitations of the present study, and the goals for future research.
