Psychometric Properties of the Greek-University of California, Los Angeles Loneliness Scale-Version 3 in a Sample of People with Human Immunodeficiency Virus

Aims: The aim of this study was to validate the Greek translation of the University of California, Los Angeles Loneliness Scale (UCLA) in Greek adults with HIV. Methods: The UCLA Loneliness scale (version 3) was administered to 140 people with HIV. Participants also completed the Greek Hospital Anxiety and Depression Scale (G-HADS). Validity and reliability analyses were performed. Results: The Cronbach’s α coefficient for the total UCLA score was 0.9. Test-retest reliability analysis in a subgroup of patients (n = 40) revealed good short-term stability over a 2-week interval (ICC 0.8 - 0.9, p < 0.0005). Exploratory factor analysis generated a three factors structure for the Greek translation. Convergent validity was supported through the scale’s high correlations with G-HADS anxiety (0.382, p < 0.01) and depression (0.524, p < 0.005). Conclusion: The Greek UCLA Loneliness scale (version 3) is a valid and reliable instrument that can be usefully implemented into clinical practice in order to diagnose and treat loneliness among the Greek HIV positive patients.
