1. Interpersonal Functioning in Borderline Personality ("Interpersonal Functioning")

15-item questionnaire adapted from a measure of Non-suicidal self-injury (NSSI) developed by Klonsky & Olino. The internally adapted version assesses lifetime and past-year frequency of 13 different NSSI behaviors. Behaviors must have been performed intentionally and without suicidal intent.

From Klonsky & Olino (2008): “A questionnaire assessed lifetime frequency of 12 different NSSI behaviors performed “intentionally (i.e., on purpose) and without suicidal intent” (i.e., banging/hitting self, biting, burning, carving, cutting, wound picking, needle sticking, pinching, hair pulling, rubbing skin against rough surfaces, severe scratching, and swallowing chemicals).
Data Notes: The original measure assessed lifetime frequency only, whereas our adaptation added items for the last 12 months.

From Klonsky & Olino (2008): Reliability and validity were examined in a sample of 761 college students. Internal consistency of the 12 NSSI behaviors was excellent (α = .84). Item-total correlations for the behaviors ranged from .22 (swallowing chemicals) to .60 (banging/hitting self), with a median of .52. One-to-four week test–retest reliability was examined in a subsample of 59 college students. Test–retest reliability of the omnibus NSSI scale was .85. Spearman correlations between Time 1 and Time 2 reports of lifetime frequency of NSSI behaviors ranged from .54 (pinching) to .94 (interfering with wound healing), with a median of .74 indicating good reliability.
