What do therapists with prior experience treating trichotillomania do differently?

Area of Science:

• Psychiatry
• Psychology
• Behavioral Science

Background:

• Therapist experience is not always linked to better outcomes.
• Specific experience with a disorder or treatment protocol may be beneficial.
• Previous findings suggest experienced trichotillomania (TTM) therapists outperform novices using the Comprehensive Behavioral (ComB) model.

Purpose of the Study:

• To conduct a secondary analysis of therapist competence in TTM treatment.
• To compare experienced TTM therapists with TTM-novice therapists in a randomized controlled trial (RCT) of the ComB model.
• To identify specific therapist skills associated with treatment outcomes.

Main Methods:

• Secondary analysis of 60 session recordings from an RCT of the ComB model for TTM.
• Coding of session recordings on dimensions of therapist competence.
• Reliability analysis of coding dimensions for between-groups comparison.

Main Results:

• Experienced TTM therapists demonstrated superior session time management and complex ComB-specific skills.
• Novice TTM therapists were more effective in addressing patient nonadherence.
• Seven dimensions of therapist competence proved reliable for analysis.

Conclusions:

• Therapist expertise in TTM is associated with better outcomes, particularly in complex skill application.
• A potential need exists to refine ComB model training or implementation sequences.
• Phased implementation of ComB, starting with simpler interventions, may enhance TTM treatment efficacy.
