Age group differences and longitudinal changes in approach–avoidance sensitivity: Findings from an 8-year longitudinal study

An increasing number of studies point to normative changes in personality occurring during adulthood. We examined age group differences and longitudinal changes in approach–avoidance sensitivities across adulthood using a population-based sample of younger, midlife, and older adults (N = 7468) assessed on three occasions over an 8 year interval. Younger adults reported higher approach sensitivity (assessed using BAS-Drive and BAS-Reward subscales) relative to midlife and older adults. Approach sensitivity tended to decline between Times 1 and 3 for all age groups. Cross-sectional age differences were not evident for avoidance sensitivity at Time 1 (assessed using the BIS); however there was evidence for different patterns of change in avoidance over time across the age groups. Results are discussed in the context of lifespan developmental perspectives on self-regulation of emotion and behaviour.

► First study to examine age differences and longitudinal changes in approach–avoidance in adulthood. ► Large population-based sample assessed at three time points over 8 years. ► Younger adults report higher approach motivation (Bas-Drive, Bas-Reward) than midlife and older adults. ► Age groups reported similar initial levels of avoidance (BIS), but showed different patterns of change.
