Relations Between Anxiety Sensitivity and Attachment in Outpatients With Borderline Personality Disorder.

Borderline personality disorder (BPD) is characterized by dysregulated emotion, interpersonal relationships, and impulsivity, and is putatively linked to a known transdiagnostic risk factor, anxiety sensitivity (AS). AS is a dispositional fear of the physical, cognitive, and/or social consequences of arousal-related somatic sensations. Gratz et al. (2008) demonstrated significantly higher AS in outpatients with BPD and a predictive value of AS over and above emotion dysregulation and impulsivity. The present study sought to extend these findings with a larger sample of outpatients with BPD by investigating predictive value of AS dimensions; relations between AS and attachment style; and impact of BPD treatment on AS. Participants completed measures at three time points: pretreatment and 6 and 12 months posttreatment. AS social was the best predictor; attachment anxiety correlated positively with AS global and AS physical. AS levels significantly decreased from pretreatment to 6 months posttreatment. Clinical implications discussed include targeting AS in BPD treatment.
