Abstract

fetched live from OpenAlex

Article AbstractBackground: Trichotillomania has been considered as part of the obsessive-compulsive disorder spectrum; however, trichotillomania treatment with obsessive-compulsive disorder medications has largely been unsuccessful. Objective: To determine whether a dopaminergic treatment as used in tics and Tourette's syndrome would be effective in trichotillomania. Method: Twenty-five participants with DSM-IV trichotillomania participated in a 12-week, randomized, double-blind, placebo-controlled trial of flexible-dose olanzapine for trichotillomania. Recruitment occurred between August 2001 and December 2005, and follow-up was completed in February 2006. The primary outcome measure was the Clinical Global Impressions-Improvement (CGI-I) scale, and secondary measures of efficacy included the Yale-Brown Obsessive Compulsive Scale for Trichotillomania (TTM-YBOCS) and the Clinical Global Impressions-Severity of Illness (CGI-S) scale. Results: Eleven of 13 participants (85%) in the olanzapine group and 2 of 12 (17%) in the placebo group were considered responders according to the CGI-I (P†‰=†‰.001). There was a significant change from baseline to end point in the TTM-YBOCS (P†‰<†‰.01) and the CGI-S (P†‰<†‰.001). The mean†‰±†‰SD dose of olanzapine at end point was 10.8†‰±†‰5.7 mg/d. Twenty-one of 25 patients (84%) reported at least 1 adverse event, but no adverse events resulted in early withdrawal from the study. Conclusion: Olanzapine seems to be a safe and effective treatment for primary DSM-IV trichotillomania.

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.
