Insights
Integrated Behavior Therapy for Children with Selective Mutism (IBTSM) is a feasible and effective treatment for reducing selective mutism (SM) and social anxiety (SA) symptoms in children. The therapy also successfully decreased parental accommodation behaviors.
Area of Science:
- Child Psychology
- Behavioral Therapy
- Clinical Psychology
Background:
- Selective Mutism (SM) is an anxiety disorder characterized by a child's inability to speak in specific social situations.
- Social Anxiety (SA) often co-occurs with SM, exacerbating the child's distress and impacting social functioning.
- Parental accommodation of SM symptoms can inadvertently maintain the disorder.
Purpose of the Study:
- To evaluate the feasibility, acceptability, and efficacy of the Integrated Behavior Therapy for Children with Selective Mutism (IBTSM).
- To assess the impact of IBTSM on children's SM and social anxiety (SA) symptoms.
- To determine the effect of IBTSM on parental accommodation behaviors.
Main Methods:
- An open, uncontrolled trial involving 30 children aged 4-13 diagnosed with SM.
- Utilized the IBTSM protocol with assessments at baseline, first session, and post-treatment.
- Employed structured interviews for diagnosis, parent questionnaires for SM, SA, and accommodation, and clinician ratings for global functioning.
Main Results:
- IBTSM demonstrated acceptable dropout rates, high therapist acceptability, and no adverse events.
- Significant reductions were observed in children's SM and SA symptoms, as well as parental accommodation.
- Clinicians rated 75% of children as treatment responders.
Conclusions:
- IBTSM is a feasible, acceptable, and efficacious treatment for children with SM in clinical settings.
- The findings support the use of IBTSM for addressing SM, SA, and parental accommodation.
- Further validation through randomized controlled trials is recommended.
Abstract:
To test the hypothesis that the Integrated Behavior Therapy for Children with Selective Mutism (IBTSM), administered in a naturalistic setting, is (a) a feasible and acceptable treatment, (b) effective in reducing children's selective mutism (SM) and social anxiety (SA) symptoms, and (c) effective in reducing parents' accommodation behaviors to their children's anxiety. This was an open, uncontrolled trial with assessments at baseline, first session, and post-treatment. The study treated 30 children aged 4-13, using the IBTSM protocol. The diagnosis of SM was established by psychologists using a structured interview. The parents reported levels of SM, SA, and parental accommodation on questionnaires, and the level of children's global functioning was rated by clinicians. Feasibility and acceptability of the IBTSM were assessed using dropout rates, protocol adherence, adverse events, and therapist's acceptability ratings. The IBTSM had acceptable dropout rates, with no adverse events and high acceptability rates. Following IBTSM, children's SM and SA levels, and parents' accommodation, significantly decreased. 75% of children were rated by clinicians as treatment responders. IBTSM is a feasible, acceptable, and efficacious treatment for children with SM, utilized in clinical settings. The results of this open trial must be replicated in randomized controlled studies.
