Previous studies have found that in nonclinical samples centrality of positive events is usually higher than centrality of negative events. In this study, we investigated the centrality and its relation to valence by considering additional predictor variables (i.e., intensity, time since event, self‐concept clarity) as well as age group differences. A total of 365 participants aged between 18 and 89 reported up to 10 positive and up to 10 negative autobiographical memories. We used multilevel analysis to account for the hierarchical structure of the data. The results confirmed the higher centrality of positive events, but only for middle‐aged and older adults. Intensity contributed to the centrality of both positive and negative events, whereas self‐concept clarity was relevant regarding negative memories of young and middle‐aged adults only. Hence, the extent to which memories contribute to identity is not only depending on characteristics of memories but on the remembering person as well.

Centrality of an event (CE) is a characteristic denoting how important a life experience is to one’s identity. Usually, positive memories are more central than negative ones in the community samples. Nevertheless, there is emerging evidence showing substantial individual differences in how one perceives CE. Especially regarding age, one could expect pronounced differences due to age-related changes in personal goals. In this study, we investigated how older adults differ from young and middle-aged adults. Apart from age, we tested whether personality traits such as neuroticism and openness to experience influence the CE ratings among age groups. The sample comprised of 363 German participants, age ranging from 18 to 89 (M=49.57, SD=17.087), 67.2 % of the sample were women. Using multilevel analysis, we found the CE of positive memories to be higher in all age groups. The CE of positive events significantly differed for older adults compared to younger adults but not to the middle-aged group. With respect to personality, neuroticism had an impact only on the CE of negative memories in younger and middle-aged adults. For older adults, neither neuroticism, nor openness to experience had an impact on CE ratings. This shows that while older adults significantly differ from younger adults in the CE of positive memories, other individual differences characteristics do not have an impact on the way older adults perceive memories as central to their identity.
