The Positive and Negative Affect Relation in the Context of Stress and Age

Research suggests that the within-person inverse relationship between negative affect (NA) and positive affect (PA) indicates poorer emotional well-being, and this interaffect correlation fluctuates in relation to the context of the individual. Specifically, age, stress, and global PA all relate to changes in the interaffect correlation. The current study uses comprehensive data from the Notre Dame Study of Health & Well Being (NDHWB), which allows us to uniquely examine between-person differences in within-person change and variability in the interaffect correlation, thereby examining these constructs from a process-oriented perspective. Midlife and later life participants (N = 965) completed daily questionnaires assessing stress, NA, and PA. Three-level multi-level models illustrated that the interaffect correlation becomes more negative during times of stress, adults with greater global PA experience a stronger inverse interaffect correlation during times of stress, and days of higher stress relate to a stronger inverse interaffect correlation for older adults compared to midlife adults. The findings illustrate the idiographic nature of these relationships and suggest that later life adults and adults with high levels of global PA undergoing higher than typical stressful situations experience stronger inverse interaffect correlations.
