Examining the malleability of implicit views of aging in middle-aged and older adults.

Negative views of aging (VoA) present a motivational barrier to healthy aging. Although prior interventions have demonstrated success in making adults' negative VoA more positive, reliance on self-report-based explicit measures is insufficient to examine whether these interventions also affected individuals' implicit VoA. Thus, this study assessed the impact of the AgingPLUS program, a 4-week psychoeducational intervention, on implicit measures of VoA in a randomized controlled trial. Participants aged 45-75 years ( = 60.1 years, = 8.3) were randomized to either the AgingPLUS program (n = 162) or a health education control group ( = 173). Implicit VoA were assessed using two computer-administered tasks: the Implicit Association Test and a lexical decision-making task. Data on implicit VoA were collected at baseline and two follow-up assessments over a 32-week period and analyzed using linear mixed-effects models. The results showed limited evidence of temporal changes or group differences regarding implicit VoA. However, participants with more positive baseline implicit VoA demonstrated greater improvements in explicit VoA, particularly in their awareness of age-related gains. Overall, explicit intervention approaches, such as the AgingPLUS program, can lead to substantial improvements in adults' self-reported VoA, although their effect on implicit VoA remains unclear. The findings underscore the importance of future interventions to (a) evaluate both explicit and implicit VoA and (b) tailor intervention designs to specific outcomes to achieve sustained, long-term positive changes in negative VoA.
