Objectives: Whereas previous work has almost exclusively focused on negative emotional reactivity to daily stressors, we focus on positive emotional reactivity - changes in positive emotions in response to a stressor. We examine daily forecasting and anticipatory coping for next-day home-related stressors within the temporal space before stressors to examine positive emotional reactivity in younger and older adults.Methods: We recruited 107 younger (M age = 19.44, range 18-36) and 116 older (M age = 64.71, range 60-90) participants who completed a nine day daily online diary for 1,627 total days. Participants reported demographics on Day 1 and then stressor forecasts, anticipatory coping, stressor exposure, and positive affect on Days 2-9.Results: Older adults had more positive affect when using outcome fantasy for next-day home stressors compared to younger adults, but forecasting a home stressor was associated with a stronger increase in positive affect for younger adults compared to older adults.Conclusion: These results reveal complex and dynamic links that exist in age differences in stressor forecasting, anticipatory coping, and their association with positive affect. The context of daily stressors is important to understand the nuances of matching stressor forecasts and anticipatory coping for positive emotional well-being in younger and older adults.
