From Negative to Positive and Back Again: Polarized Affective and Relational Experience in Borderline Personality Disorder
Although borderline personality disorder is often described in terms of polarized (all-good vs. all-bad) experiences of relationships and affects, few studies have investigated this phenomenon. Using an experience-sampling diary completed by participants up to 5 random times daily for 21 days, my co-authors and I showed greater relational and affective polarity in adults with borderline personality disorder than healthy controls and associations between increases in polarity with increased reports of interpersonal stress and harmful impulsive behavior.
