A systematic review and meta-analysis of the association between age and degrees of avoidant decision-making style

Initial empirical evidence and theories suggest that decision-making may become more avoidant with age. However, recent studies provide inconsistent evidence for this effect. We conducted a systematic review and meta-analysis of 19 studies (N = 7969) to assess evidence for an association between age and avoidant decision-making style. We included studies that used the avoidant subscale of the General-Decision-Making Style (GDMS) questionnaire or the buck-passing subscale of the Melbourne Decision-Making Questionnaire (complete avoidance), or the dependent subscale of the GDMS (partial avoidance). We also assessed potential moderators of the effect, including age range for each sample, gender, culture, participant sample type, publication year, decision style subscale, and degree of avoidance (complete vs. partial). Surprisingly, the data revealed a small association between older age and less avoidant decision-making style. Moderator analysis revealed that this association applied to complete decision avoidance (the avoidant and buck-passing subscales) and not partial avoidance (the dependent subscale). Additionally, moderation by sample type suggests that decision style does not become less avoidant until after middle age. We discuss important future directions for research aimed at investigating nuances that may contribute toward avoidant decision-making style in older age.
