“I feel like so much more of myself”: The experience of modifying appearance in borderline personality disorder.

= 47) participated in a semistructured interview targeting appearance-modification experiences. Rapid qualitative analysis methods were used to sort interview content into five domains of interest: physical sensations, affect regulation, sense of self, emptiness and identity disturbance, and impulsivity. Participants described a wide range of body modifications and associated experiences. Results substantiated the potential for appearance modifications to positively impact sense of self in BPD-mitigating identity disturbance and emptiness-and revealed complex emotional consequences when these modifications do not "work." The results also challenge inferred causal relationships between nonsuicidal self-injury history and appearance modification: Although participants reported sensory similarities between the behaviors, appearance modifications carried specific positive connotations and consequences that nonsuicidal self-injury did not. This study reveals a complex and nuanced picture of appearance modification in BPD, with particular implications for identity affirmation and mood induction. The results identify common themes across highly variable and personal narratives, opening a window into BPD lived experience. (PsycInfo Database Record (c) 2026 APA, all rights reserved).
