An Exploratory Psychometric Network Analysis of Loneliness Scales in a Sample of Older Adults.
Objectives: To examine the relationships within and between commonly used measures ofloneliness to determine the suitability of the measures in older adults. Further, todetermine items of key importance to the measurement of loneliness. Methods: Data wereobtained from 350 older adults via completion of an online survey. Four measures ofloneliness were completed. These were the UCLA Loneliness scale (Version 3), the de JongGierveld Loneliness Scale, the Social and Emotional Loneliness Scale for Adults (ShortVersion) and a direct measure of loneliness. Results: Analysis via a regularized partialcorrelation network and via clique percolation revealed that only the SELSA-Sencompassed loneliness relating to deficits in social, family and romantic relationships. Theremaining measures tapped mostly into social loneliness alone. The direct measure ofloneliness had the strongest connection to the UCLA item-4 and the de Jong Giervelditem-1 exhibited the strongest bridge centrality, being a member of the most clusters.Discussion: The results indicate that should researchers be interested in assessingloneliness resulting from specific relationships, then the SELSA-S would be the mostsuitable measure. Whereas the other measures are suitable for assessing loneliness moregenerally. The results further suggest that the de Jong Gierveld item-1 may be a moresuitable direct measure of loneliness than that currently employed as it taps into a greaternumber of relationships.
