Investigation of Integrated Behavior Therapy for Selective Mutism: A Replicated Single-Case Study Design
Bibliographic record
Abstract
Selective Mutism (SM) is a rare but potentially debilitating disorder characterized by a lack of speech in certain settings where speaking is expected. This study examined the effectiveness of a shortened version (12 sessions over 18 weeks) of Integrated Behavior Therapy for Selective Mutism (IBTSM; Bergman, 2013) in increasing speech and relieving anxiety for two four-year-old males with SM via a replicated single-case design. Treatment effectiveness, integrity, and acceptability were measured at baseline, throughout treatment, and at a three-month follow-up. Treatment integrity was excellent for both cases. SM severity ratings decreased from baseline to end-of-treatment, and again at follow-up, for each case. Verbal communication increased at end-of-treatment and follow-up, and significant decreases in social anxiety were seen across both cases by the three-month follow-up. Parents rated the shortened IBTSM as highly acceptable, effective, and efficient. Future studies should explore the effectiveness of varying lengths of IBTSM.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
