Nonjudgment as a moderator of the relationship between present-centered awareness and borderline features: Synergistic interactions in mindfulness assessment

The symptoms of borderline personality disorder (BPD) have been characterized as deficits in mindfulness. Mindfulness can be defined as nonjudgmental, present-centered awareness. The present study investigates the theory that, consistent with this conceptualization, the extent to which acting with awareness predicts reduced BPD features and related dysfunction depends upon levels of nonjudgment. In a sample of 223 undergraduates, we calculated the interaction between awareness-based and nonjudging-based mindfulness skills using subscales of the Five Facet Mindfulness Questionnaire. Regression analyses demonstrated a significant effect of the interaction on several difficulties that are common in BPD: problems with relationships, emotion-related impulsivity, and anger rumination. For acting with awareness to benefit individuals with these difficulties, a less judgmental stance toward internal experiences may be necessary. These findings have significant treatment implications and demonstrate the importance of assessing mindfulness as a multifaceted, synergistic construct.

► We provide further support for deficits in mindfulness in BPD.
► Statistical interactions reveal synergistic effects of mindfulness skills.
► Nonjudgment may be necessary for acting with awareness to benefit people with BPD.
