Associations between emotional instability, coping, and health outcomes among patients with non-cardiac chest pain.

The main aim of this study was to examine the relationship of emotional instability with illness worry and perceived limitations due to chest pain, and investigate to what degree any associations are mediated by the following chest pain-related coping styles: acceptance, seeking emotional support, seeking instrumental support, and avoidance. Self-reported measures from 94 participants with non-cardiac chest pain were collected. The results showed a relationship between emotional instability, illness worry, and perceived limitations due to chest pain. Moreover, this relationship was mediated by the coping styles avoidance and acceptance.
