Abstract
Objectives: Higher well-being in older adults compared to young adults is a well-known phenomenon. However, the variables associated with this effect are still uncertain. Negative repetitive thinking (rumination) is a transdiagnostic variable related to psychopathology. It is strongly associated with depression and a lack of specificity in autobiographical retrieval. This research explores age differences in the association of rumination with mood, autobiographical memories and working memory.
Method: Two groups of participants (older adults versus young adults), recruited through a public announcement, were compared in a cross-sectional study.
Results: Older adults ruminated less than young participants. Rumination was positively associated with depression scores but not with working memory scores in both samples. More importantly, the interaction between brooding rumination and negative autobiographical memories was the only significant variable to explain the variance of mood scores in young participants. However, in older participants, the interaction between brooding and positive autobiographical memories significantly explained the variance of mood scores. Digit span forward and the interaction of brooding by negative autobiographical memories also significantly explained mood scores in older adults.
Conclusion: These results suggest that a different interaction between brooding rumination and the valence of autobiographical memories may be a relevant variable associated with mood differences by age.
