Insights

Selective mutism (SM) treatment using modular cognitive behavioral therapy (MCBT) shows promising long-term results in children. This therapy effectively reduces SM and related anxiety symptoms, with a high recovery rate observed.

Area of Science:

  • Child Psychology
  • Clinical Psychiatry
  • Behavioral Therapy

Background:

  • Selective mutism (SM) is an underdiagnosed childhood disorder with limited empirical data on treatment outcomes.
  • Existing research on SM treatment, particularly cognitive-behavioral therapy, often consists of small, uncontrolled case reports.
  • Long-term outcome data for children with SM following treatment are scarce.

Purpose of the Study:

  • To evaluate the long-term effectiveness of modular cognitive behavioral therapy (MCBT) for children diagnosed with selective mutism.
  • To assess the impact of MCBT on SM symptoms and comorbid anxiety disorders.
  • To investigate the recovery rates and long-term outcomes in a cohort of children treated for SM.

Main Methods:

  • A retrospective naturalistic study design was employed.
  • Parents of 36 children meeting SM diagnostic criteria and receiving MCBT were invited for follow-up.
  • Data were collected through structured interviews and questionnaires, including the Selective Mutism Questionnaire (SMQ), for 24 evaluated subjects.

Main Results:

  • The study evaluated 24 children with a mean age of 9.3 years at follow-up.
  • Significant improvements were observed in SM, social anxiety disorder, and specific phobia symptoms from treatment initiation to follow-up.
  • The overall recovery rate for selective mutism was 84.2%.

Conclusions:

  • Modular cognitive behavioral therapy (MCBT) is a feasible and potentially effective treatment for selective mutism in children.
  • Early intervention appears more effective than treatment initiated at older ages.
  • SM-focused MCBT contributes to a reduction in psychiatric comorbidities, including separation anxiety and specific phobias.
