Adaptation of a short-form nostalgia scale: convergent and divergent validity in a sample of French elders.

Nostalgia is an efficient coping strategy that helps elders overcome major life transitions. To better explore the protective functions of nostalgia, we set out to adapt a short-form nostalgia scale to French elders and examine its convergent and divergent validity in terms of self-esteem, depression, and wellbeing. Participants were 175 institutionalized French elders. After providing their written informed consent, they were asked to complete a demographic information form and respond to four questionnaires probing self-esteem, nostalgia, depression, and wellbeing. Principal component analyses and fit indices were used to explore convergent validity. An 8-item version showed acceptable psychometric properties and measured two dimensions of nostalgia. Spearman correlations were conducted to explore divergent validity. In our sample, the first dimension was negatively associated with global cognitive functioning, while the second dimension was positively associated with self-esteem and wellbeing, and negatively associated with depression. The negative relationship between depression and nostalgia supports the idea that nostalgia is a positive concept. Future research should explore factors liable to impact nostalgia, such as cultural differences and reminiscence therapy.
