Abstract
Objectives: The present study examined age differences among older adults in the daily co-occurrence of affect and its potential role in buffering the negative effects of health stressors.
Design: Participants were from the Veterans Affairs Normative Aging Study and included 249 young-old adults (age = 60–79 years, M = 71.6) and 64 old-old adults (age = 80–89, M = 82.9) who completed questionnaires assessing stressors, physical health symptoms, and positive and negative affect for eight consecutive days.
Results: An independent samples t-test showed young-old and old-old adults did not significantly differ in their mean levels of daily co-occurrence of affect. The between-person relationships among stressors, health and daily co-occurrence of affect revealed that neither stressors nor health were significantly related to daily co-occurrence of affect. However, results from a multilevel model revealed a three-way cross-level interaction (health stressor × age group × co-occurrence of affect) where old-old adults with higher levels of co-occurrence of affect were less emotionally reactive to health stressors than young-old adults.
Conclusion: These findings provide support for the assertion that co-occurrence of affect functions in an adaptive capacity and highlight the importance of examining domain-specific stressors.

Notes
1. To rule out the possibility that fluctuations in negative affect and positive affect were more important than mean co-occurrence of affect, we calculated each individual’s within-person standard deviation scores for both positive and negative affect. These scores were then simultaneously entered into the previous model. Results did not change and the three-way cross-level interaction (health stressor × age × co-occurrence of affect) remained significant when fluctuations in positive and negative affect were included as covariates.
