Objectives:
Older adults (OA; 65+) can become cognitively fused with negative attitudes and stereotypes. Given the verbal nature of ageist stereotypes, mindfulness and acceptance-based practices (MABPs) may help the impact of negative aging attitudes by increasing non-judgmental awareness, cognitive defusion, and acceptance. As part of a larger study, this project examined whether an Acceptance and Commitment Therapy (ACT) consistent MABP would reduce negative aging attitudes using an experimental design. We hypothesized that assignment to the MABP condition would be associated with lower negative aging attitudes for both OAs and university undergraduates (18-25).
Method:
Both OAs (N = 60) and undergraduate student (N = 60) participants were assigned to the experimental or comparison condition (MABP vs. sit-and-think task) and were then presented negative ageist stereotypes assessed with two ageism measures.
Results:
Following the MABP, undergraduates who received a MABP had significantly lower ageism scores than did undergraduates who did not, while OAs endorsed higher scores on ageism after receiving the MABP (vs comparison group; ps < .05). There was no significant condition by age sample interaction effect.
Conclusion:
Results suggest that undergraduates and OAs may have different strategies for recontextualizing ageist attitudes, with OAs possibly employing different strategies when confronted with ageism in an experimental context. Overall, aging education, OA experimental research, and evidence-based interventions for negative beliefs about aging are needed. Limitations and future directions are discussed.
