Be Your Own Superhero: A Case of a Young Boy With Selective Mutism and Complex Comorbidities

This case study outlines the treatment of a 5-year-old Caucasian male who presented with symptoms of selective mutism (SM) along with significant impairment related to comorbid anxiety and speech difficulties. To address these symptoms, Integrated Behavior Therapy for Selective Mutism (IBTSM) was utilized for the treatment of this young boy’s SM and comorbid anxiety. An attachment focus was incorporated as a framework for conceptualizing his SM symptoms. As the treatment of this young boy’s symptoms proceeded, it became clear that his underlying speech difficulties needed to be addressed as well, as these difficulties were preventing expected progress to occur. Thus, this young boy’s treatment was individualized to fit his unique difficulties. In shifting the treatment focus to “being brave like a superhero,” significant decreases were achieved in this young boy’s overall internalizing and Diagnostic and Statistical Manual of Mental Disorders ( DSM)-related anxiety symptoms, facilitating a successful transition to speech and language therapy. This case study is distinctive in its description of the complexities that may come along with treating symptoms that appear consistent with SM along with other comorbid conditions and nuanced circumstances.

Latent Class Symptom Profiles of Selective Mutism: Identification and Linkage to Temperamental and Social Constructs

Selective mutism (SM) is a stable, debilitating psychiatric disorder in which a child fails to speak in most public situations. Considerable debate exists as to the typology of this population, with empirically-based studies pointing to possible dimensions of anxiety, oppositionality, and communication problems, among other aspects. Little work has juxtaposed identified symptom profiles with key temperamental and social constructs often implicated in SM. The present study examined a large, diverse, non-clinical, international sample of children aged 6-10 years with SM to empirically identify symptom profiles and to link these profiles to key aspects of temperament (i.e., emotionality, shyness, sociability, activity) and social functioning (i.e., social problems, social competence). Exploratory and confirmatory factor analysis revealed anxiety/distress, oppositionality, and inattention domains. In addition, latent class analysis revealed nuanced profiles labeled as (1) moderately anxious, oppositional, and inattentive, (2) highly anxious, and moderately oppositional and inattentive, and (3) mildly to moderately anxious, and mildly oppositional and inattentive. Class 2 was the most impaired group and was associated with greater emotionality, shyness, and social problems. Class 3 was the least impaired group and was associated with better sociability and social competence and activity. Class 1 was largely between the other classes, demonstrating less shyness and social problems than Class 2. The results help confirm previous findings of anxiety and oppositional profiles among children with SM but that nuanced classes may indicate subtle variations in impairment. The results have implications not only for subtyping this population but also for refining assessment and case conceptualization strategies and pursuing personalized and perhaps less lengthy treatment.

Personalized Individual and Group Therapy for Multifaceted Selective Mutism

Selective mutism refers to a persistent and debilitating condition in which a child fails or refuses to speak in public situations. Research on treatment for selective mutism has progressed in recent years toward a more personalized model based on clinical profiles unique to a given child. Such profiles may include aspects of anxiety, oppositional behaviors, and communication problems as well as operant factors that maintain selective mutism. The present case represents a 6-year-old child with selective mutism with a multifaceted clinical profile that included internalizing and externalizing behavior problems with multiple operant factors. Initial personalized individual therapy focused on anxiety and contingency management procedures to address school refusal behavior and to lay the groundwork for later treatment of selective mutism. Group therapy with parent and child components focused on these procedures in more detail in addition to social skills development. Each component included detailed hierarchies for increasing frequency and audibility of speech in a clinic setting as well as in community and school settings.

Ties of silence--Family lived experience of selective mutism in identical twins

This article is based on an in-depth interview with a pair of twins diagnosed with selective mutism and their parents 2 years after recovery. Selective mutism (SM) is a rare disorder, and identical twins sharing the condition are extremely rare. The twins developed SM simultaneously during their first year of school. The treatment and follow-up they received for several years are briefly described in this article. The interview explored the children's and their parents' narratives about the origin of the condition, the challenges it entailed in their daily lives, and what they found helpful in the treatment they were offered. In the interview, the children conveyed experiences that even the parents were unaware of and revealed examples of daily life-traumas for which they were unable to obtain support and help. The whole family was trapped in the silence. The twins and their parents emphasized different aspects in terms of what they believed were helpful. The implications of these findings for our understanding and treatment of children with SM are discussed, as well as the potential of service user involvement in child and adolescent mental health research.

Anxiety and oppositional behavior profiles among youth with selective mutism

Selective mutism (SM) is a debilitating condition in which a child does not speak in social situations where speech is expected. The clinical conceptualization of SM has been debated historically, with evidence pointing partly to anxious and oppositional behavior profiles. Behavioral characteristics were examined in a clinical sample of 57 youth formally diagnosed with selective mutism. Parents rated children across internalizing and externalizing behaviors on the Child Behavior Checklist. Eighteen highly rated items were subjected to exploratory and then confirmatory factor analysis. Anxiety and oppositional behavior factors were derived. The anxious behavior profile was associated with social anxiety disorder symptoms, social problems, and aggressive behaviors but not oppositional defiant disorder symptoms. The oppositional behavior profile was associated with aggressive behaviors, oppositional defiant disorder symptoms, social problems, and inversely to social anxiety disorder symptoms. Results are consistent with emerging research regarding subgroups of children with SM. Behavior profiles are discussed as well with respect to assessment and treatment implications.

LEARNING OUTCOMES

Readers will learn about the nature of children with selective mutism as well as behaviors that differentiate anxious and oppositional behavior profiles. Items that comprise anxious and oppositional behavior profiles are presented. These item profiles may have ramifications for assessment and treatment.

Selective Mutism in Early Childhood

Selective mutism (SM) is a relatively uncommon disorder in childhood, occurring in only 0.3 to 1.8 children per thousand. In early childhood, diagnosing SM can be particularly challenging, and the condition often goes unrecognized until the school years. Given the potential comorbidity of anxiety and communication deficits, treatment can be challenging and attendance in early childhood educational programs allows intervention in a contextually sensitive way that may also help address comorbidities and promote generalization. Thus, this case study of an African American preschool boy highlights the unique obstacles and opportunities of assessment and treatment in a preschool setting. Furthermore, we describe a three-step behavioral approach to addressing SM in collaboration with educators over a 3-month period. Substantive research indicates that early intervention with SM is associated with decreased likelihood of developing an anxiety-related disorder later in childhood; therefore, tailored assessment and intervention in early childhood within a community-based setting may be extremely useful.
