Abstract

fetched live from OpenAlex

<b><i>Introduction:</i></b> Evidence-based psychotherapies for borderline personality disorder (BPD) are lengthy, posing a barrier to their access. Brief psychotherapy may achieve comparable outcomes to long-term psychotherapy for BPD. Evidence is needed regarding the comparative effectiveness of short- versus long-term psychotherapy for BPD. <b><i>Objective:</i></b> The aim was to determine if 6 months of Dialectical Behavior Therapy (DBT) is noninferior to 12 months of DBT in terms of clinical effectiveness. <b><i>Methods:</i></b> This two-arm, single-blinded, randomized controlled noninferiority trial with suicidal or self-harming patients with BPD was conducted at two sites in Canada. Participants (<i>N</i> = 240, <i>M</i> (SD)<sub>age</sub> = 28.27 (8.62), 79% females) were randomized to receive either 6 (DBT-6) or 12 months (DBT-12) of comprehensive DBT. Masked assessors obtained measures of clinical effectiveness at baseline and every 3 months, ending at month 24. DBT-6 and DBT-12 were outpatient treatments consisting of weekly individual therapy sessions, weekly DBT skills training group sessions, telephone consultation as needed, and weekly therapist consultation team meetings. <b><i>Results:</i></b> The noninferiority hypothesis was supported for the primary outcome, total self-harm (6 months: margin = −1.94, <i>M</i><sub>diff</sub> [95% CI] = 0.16 [−0.14, 0.46]; 12 months: margin = −1.47, <i>M</i><sub>diff</sub> [95% CI] = 0.04 [−0.17, 0.23]; 24 months: margin = −1.25, <i>M</i><sub>diff</sub> [95% CI] = 0.12 [−0.02, 0.36]). Results also supported noninferiority of DBT-6 for general psychopathology and coping skills at 24 months. Furthermore, DBT-6 participants showed more rapid reductions in BPD symptoms and general psychopathology. There were no between-group differences in dropout rates. <b><i>Conclusions:</i></b> The noninferiority of a briefer yet comprehensive treatment for BPD has potential to reduce barriers to treatment access.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
