Psychometric analysis of the short form UCLA Loneliness Scale (ULS 6) in older adults
The aim of this investigation was to present new empirical evidence regarding the psychometric properties of the short form UCLA Loneliness Scale (ULS 6) among Portuguese older people. The study included 1,154 persons (60 women and 40 men) aged 60 90 (M 71.26; SD 6.66) The psychometric properties of the ULS 6 were analysed by means of confirmatory factor analysis, internal consistency, and criterion related validity methods. Confirmatory factor analysis supported a unidimensional structure of the measure with adequate values of various fit indices. The ULS 6 presented satisfactory psychometric properties, with a high level of internal consistency. Furthermore, the ULS 6 showed a negative relationship with self esteem, satisfaction with life, and positive affect; and a positive one with negative affect. The results confirm that the ULS 6 provides a brief, psychometrically sound measure of loneliness that is appropriate for use among older adults.
