The good old times?!: the relationship between regret and rumination in older adults.

Worst outcomes in the Devil's task elicited the highest levels of regret in older adults, supporting the idea that regret arises from missed opportunities and blocked goal progress.

• 56 older adults aged 65 or older participated in the study
• Participants performed a sequential binary choice risk-taking task (the Devil's task) specifically designed to elicit state regret and self-critical rumination
• Outcome quality was systematically varied to produce different levels of regret as a function of decision outcomes

Regret and self-critical rumination during the task were positively correlated in older adults.

• State regret and state self-critical rumination were measured during the Devil's task
• The positive correlation supports the idea of a self-sustaining cycle between the two constructs
• Both were assessed as momentary (state-level) measures during task performance

Both trait-level rumination and momentary self-critical rumination at the start of the study predicted heightened regret following the risk-taking computer task.

• Participants completed a questionnaire assessing trait-level tendency for self-critical rumination prior to the task
• Momentary (state) self-critical rumination was also measured at the start of the study
• Both trait and state measures of rumination independently predicted subsequent regret levels following task completion

Trait-level rumination and momentary self-critical rumination at the start of the study predicted subsequent self-critical rumination following the risk-taking task.

• Both trait-level and state-level rumination measured before the task were predictive of post-task self-critical rumination
• This suggests a continuity of ruminative responding across time and context in older adults
• The sample consisted of 56 older adults (aged 65 or older)

The self-perpetuating cycle between regret and rumination in older adults occurred independently of habitual rumination tendencies, contrasting with findings in younger adults.

• Trait-level rumination did not moderate the relationship between regret and self-critical rumination during the task
• This pattern contrasts with findings in younger adults, where habitual rumination tendencies have been found to intensify the regret-rumination connection
• The finding suggests that the regret-rumination cycle may operate differently across the lifespan

The study highlights the need to consider the interplay between regret and self-critical rumination in mental health interventions for older adults regardless of their habitual tendency to ruminate.

• Because the cycle between regret and rumination was independent of trait rumination, all older adults may be susceptible regardless of their baseline ruminative tendencies
• The findings suggest that interventions targeting regret or rumination in isolation may be insufficient
• The authors emphasize that reflecting on missed opportunities can create a self-sustaining cycle potentially affecting mental health in aging populations
