Borderline personality disorder symptoms and pain in college students: The role of emotional suppression

Borderline personality disorder (BPD) is associated with higher rates of pain conditions and greater pain impairment. Past research implicates emotional suppression in acute pain tolerance; thus, emotional suppression may contribute to pain interference among those with high BPD features. Participants were 89 university students who completed measures of BPD features, and complied with 2-week daily diary procedures assessing suppression of emotional thoughts associated with social and nonsocial stressors, distress, pain severity, and interference. Multilevel models revealed a BPD × Suppression × Distress interaction, such that suppression in response to social (but not nonsocial) stressors in the context of high distress was related to pain interference when controlling for pain severity among those with high, but not low, BPD features. These findings suggest that suppression of emotionally relevant thoughts in response to high distress may contribute to the functional impairment from pain among those with high BPD symptoms.
