Experiential avoidance in idiographic, autobiographical memories: construct validity and links to social anxiety, depressive, and anger symptoms.

Experiential avoidance, or attempts to alter or avoid undesirable thoughts and feelings, has been theorized to be relevant to the development of emotional disturbances, particularly anxiety problems. Prior work has relied on two methodologies: global self-report measures or laboratory manipulations. To better understand links between experiential avoidance and emotional disturbances, we measured experiential avoidance in the context of prominent anxious autobiographical events. Trained raters coded events for emotionality and reliance on experiential avoidance. Our interest was whether experiential avoidance could be measured as a memory characteristic and how it relates to social anxiety, depressive, and anger symptoms. As evidence of construct validity, experiential avoidance ratings were related to more intense negative emotions and coping difficulties during anxious events, memory vividness, and emotion suppression tendencies. Experiential avoidance was positively related to social anxiety and depressive symptoms and predicted an increase in social anxiety over a 3-month period; findings could not be attributed to the emotionality of memories. In contrast, no relations were found with inward or outward expressions of anger, or longitudinal change in depressive or anger symptoms. Results suggest that experiential avoidance is an important dimension of people's life narratives and particularly relevant to social anxiety problems.

Coping self-efficacy as a mediator between catastrophizing and physical functioning: treatment target selection in an osteoarthritis sample.

The purpose of this study was to assess the relative effects of coping self-efficacy and catastrophizing on physical functioning. Over a 9-month period, studying changes in self-efficacy as possible mediator between catastrophizing changes and physical functioning changes might provide evidence for the most promising treatment target. Data came from a randomized, longitudinal controlled trial comparing exercise, self-management and the two combined to treat 254 individuals with early knee osteoarthritis. A secondary analysis using a bootstrapped linear mixed-effects mediational model produced estimates of both the direct and indirect effects. Results indicated that self-efficacy partially mediated the effect between catastrophizing and physical functioning suggesting that self-efficacy was the more direct treatment target compared to catastrophizing. Treatments targeting both self-efficacy and catastrophizing may have greater impact on physical functioning compared to treatments that focus on only one.
