Interpersonal contrast avoidance as a mechanism for the maintenance of worry.

Despite consistent links between interpersonal problems and worry, mechanisms explaining this relationship remain unknown. The Contrast Avoidance Model (CAM; Newman & Llera, 2011) posits that individuals at risk for chronic worry and generalized anxiety disorder (GAD) fear sudden negative mood shifts, using worry to perpetuate negative moods and avoid these negative emotional contrasts. We propose interpersonal (IP) contrast avoidance (e.g., acting friendly to prevent others from causing mood shifts) as a novel explanation for interpersonal dysfunction in worriers. This study investigated IP contrast avoidance and worry in two samples. A nonclinical sample ranging in GAD symptoms (Study 1; N = 92) reported IP problems at baseline then IP contrast avoidance and worry over eight weeks (637 diaries). As expected, baseline IP problems prospectively predicted worry indirectly through chronic IP contrast avoidance. Affiliative, submissive, cold, and total IP contrast avoidance strategies predicted same-week and lagged next-week worry increases; affiliative, submissive, and total strategies also predicted maintenance of worry over eight weeks in growth models. Lastly, Study 2 showed the relevance of IP contrast avoidance strategies in a treatment-seeking clinical sample (N = 40), correlating with interpersonal problems and worry. Overall, results provide proof-of-concept for extending the CAM to the interpersonal domain.

Prospective Investigation of the Contrast Avoidance Model of Generalized Anxiety and Worry.

The factors that maintain generalized anxiety disorder (GAD) symptoms and worry over time are not entirely clear. The Contrast Avoidance Model (CAM) postulates that individuals at risk for pathological worry and GAD symptoms uniquely fear emotional shifts from neutral or positive emotions into negative emotional states, and consequently use worry to maintain negative emotion in order to avoid shifts or blunt the effect of negative contrasts. This model has received support in laboratory experiments, but has not been investigated prospectively in the naturalistic context of daily life. The present study tested the CAM in a longitudinal experience sampling study with a subclinical sample. Participants selected to represent a broad range of symptoms (N = 92) completed baseline measures of GAD and depression symptoms, and eight weekly assessments of worry, experiences of negative emotional contrasts during their worst event of the week, and situation-specific negative emotion. Consistent with the CAM, GAD symptoms prospectively predicted higher endorsement of negative contrast experiences as worst events, independent of depression symptoms. Unsurprisingly, higher negative contrasts predicted higher negative emotion. However, both higher baseline GAD symptoms and weekly worry uniquely moderated (reduced) this relationship, providing consistent support for the idea that worry may blunt the emotional effects of contrasts. Depression symptoms did not have the same moderating effect. These findings support the CAM in an ecologically valid context.
