Stress reactivity and coping in seasonal and nonseasonal depression.

Stress, stress reactivity, and coping skill use were examined in individuals with seasonal depression, nonseasonal depression, and nondepressed controls. Although participants in the two depressed groups reported using more avoidance coping strategies than controls, only participants in the seasonal depressed group reported using more season-specific coping (i.e., light-related strategies) than participants in the nonseasonal depressed and control groups. Individuals in the seasonal depressed group also reporting using acceptance coping strategies less frequently than individuals in the control group. Only participants in the nonseasonal depressed group, however, exhibited greater psychophysiological arousal in reaction to a laboratory stressor (i.e., unsolvable anagram task) when compared to participants in the seasonal and nondepressed control groups. Participants in both depressed groups reported greater impact of negative life events during the past 6 months than did controls. Similarities and differences in the two types of depression may have implications for the conceptualization and treatment of seasonal depression.

The role of anxiety level, coping styles, and cycle phase in menstrual distress.

Using three samples, researchers investigated the relation between various anxiety levels, coping strategy use, and menstrual cycle phase to menstrual distress. In Studies 1 and 2, women low in anxiety sensitivity used more acceptance coping strategies and women high in anxiety sensitivity reported using more maladaptive coping strategies. In Study 2, women with medium anxiety sensitivity reported similar coping strategies to women low in anxiety. Menstrual cycle phase did not differentially affect coping strategy use in women varying in anxiety sensitivity levels in Studies 1 and 2. In addition to depressed mood emerging as a significant predictor of premenstrual distress in these two studies for all participants, avoidance coping for women high in anxiety sensitivity and problem-focused coping for women low in anxiety sensitivity were also significant predictors of premenstrual distress. In Study 3, during the premenstrual phase, women with panic disorder, compared to controls, reported using more avoidance coping whereas controls reported used more active coping and seeking social support for emotional and instrumental reasons. Results are discussed within a continuity model from high anxiety sensitivity to anxiety disorder for maladaptive coping and menstrual distress.
