Health-related stress, affect, and depressive symptoms experienced by caregiving mothers of adults with a developmental disability.

The interrelationships among health-related stress, positive and negative affect, and depressive symptoms patterned in the dynamic model of affect (J. Reich, A. Zautra, & M. Davis, 2003) were examined using data from 932 women having an adult child with a developmental disability. Results indicate that women experience a moderate inverse correlation between positive and negative affect under conditions of low levels of health-related stress, whereas at high levels of stress, positive and negative affect become more strongly inversely correlated. Under high-stress conditions, both negative affect and positive affect have a stronger relationship to depressive symptoms than they do under low-stress conditions.
