Commentary to Nicastro et al. (2016), Borderline Personality Disorder and Emotion Dysregulation
Borderline Personality Disorder and Emotion Dysregulation volume 3, Article number: 15 (2016)
We realized that the paper by Nicastro et al.  did not discuss all the studies involving the French version of the BSL-23. Parallel to Nicastro and colleagues’ translation, Kramer et al.  have used a slightly different French translation of the BSL-23 which had previously received approval by the authors of the scale (M. Bohus, personal communication, July 2010). This independent translation differs only on 4 items - a matter of nuance - from the Nicastro and colleagues translation. In their treatment study, Kramer and colleagues randomized N = 85 patients with Borderline Personality Disorder (BPD) and administered the BSL-23 pre and post treatment for n = 61 patients. They found, for a psychiatric treatment over 10 sessions, a small, but significant, pre-post effect (d = .28, intent to treat). In a different randomized controlled trial for N = 31 patients with BPD, the same author group found a small, but significant, between-group effect favoring a short-term version of dialectical-behavior skills training (d = .23; completers; ). Given the interest of the BSL-23 in French speaking samples of individuals with BPD, the current validation study by Nicastro et al.  is highly welcome and will help encourage the use of the scale in further psychotherapy studies.
