Abstract
Selective mutism is an anxiety disorder in which an individual is unable to speak in certain social situations though may speak normally in other settings (Hua & Major, 2016). Selective mutism in adults is rare, though people with this condition might have other methods of communicating their needs outside of verbal communication. Healthcare professionals rely on a patient's ability to communicate to establish if they have decision-making capacity. This commentary responds to a case of a young adult patient with selective mutism and social anxieties that significantly limited his ability to communicate with anyone in the healthcare team. This required a creative, patient-centered approach to engage in meaningful communication.

Abstract
Selective mutism (SM) is a poorly understood condition, and debate continues regarding its etiology and classification. Research suggests that a genetic vulnerability may play a role in the development of the disorder which may be compounded by anxious and over-protective parenting. While previous studies supported the role of parenting styles in the development of SM, most of them examined child and parent factors in isolation. The current study examined how the interactions between child internalizing and externalizing behaviors (anxiety and oppositionality, respectively) and parenting styles (authoritative, permissive, and authoritarian) are associated with SM diagnosis. The study included 285 children aged 3-7 years (57.2% females), and their parents (66 children with SM and 219 typically developed children). Parents completed questionnaires about child social anxiety, oppositional behavior, SM severity, and their parenting style. Results showed that parents of children with SM reported lower levels of authoritative practices than those of typically developed children. We also found that child social anxiety and oppositionality moderated the effects of authoritative and authoritarian parenting practices on SM diagnosis. Our results suggest that child anxiety and oppositionality may explain the different susceptibility of children to adaptive and maladaptive parenting styles.

Abstract
The purpose of this study was to study psychopathological and temperamental correlates of selective mutism (SM) (symptoms) in a mixed sample of non-clinical (n = 127) and clinically referred (n = 42, of whom 25 displayed the selective non-speaking behavior that is prototypical for SM) 6- to 12-year-old children. Parents completed questionnaires to measure their child's symptom levels of selective mutism, social anxiety, autism spectrum disorder, and the temperament trait of behavioral inhibition. The results first and foremost showed that SM symptoms were clearly linked to social anxiety and an anxiety-prone temperament (behavioral inhibition), but findings also suggested that autism spectrum problems are involved in the selective non-speaking behavior of children. While the latter result should be interpreted with caution given the methodological shortcomings of this study, findings align well with the notion that SM is a heterogeneous psychiatric condition and that clinical assessment and treatment need to take this diversity into account.

Abstract
Understanding the symptoms of a mental disorder is essential for accurate diagnosis or selecting appropriate treatment targets. Despite this, there is a surprising lack of systematic research on the symptoms of selective mutism (SM). While the DSM-5 defines failure to speak as the only core symptom of SM, sparse research suggests that children with SM may experience additional symptoms. Previous studies have been limited in their identification of symptoms of SM, either by using a predefined set of symptoms or by only asking for anxiety-specific symptoms. This may have resulted in important symptoms being overlooked. In this study, we provided n = 86 parents of children and adolescents with SM (3-18 years) with a symptom definition appropriate for the target group. Additionally, parents were asked an open-ended question about any other symptoms they had observed in their children, beyond the failure to speak. The symptoms reported were categorized using qualitative content analysis (QCA) and examined for frequency and association with symptom severity. Ten different symptom categories were identified, with fear, freezing, and avoidance/security behaviors being the most prevalent. On average, parents reported M = 4.74 (SD = 2.37) symptoms from different symptom categories. Only fear was found to be related to symptom severity of SM. As the findings suggest that SM encompasses various symptoms beyond failure to speak, a more sophisticated understanding of SM as a mental disorder with multiple symptoms seems essential. The clinical implications of this are discussed in further detail.

Abstract
Clinical presentations of selective mutism (SM) vary widely across affected youth. Although studies have explored general externalizing problems in youth with SM, research has not specifically examined patterns of irritability. Relatedly, research has not considered how affected families differentially accommodate the anxiety of youth with SM as a function of the child's temper outbursts (i.e., phasic irritability) and general angry mood (i.e., tonic irritability). Data were drawn from a sample of treatment-seeking children and adolescents with a primary diagnosis of selective mutism (N = 152; Mean age = 6.12 years; 67.11% female), and their caregivers. Latent profile analysis (LPA) was used to identify distinct profiles in SM youth that were characterized by varying levels of phasic and/or tonic irritability. Analyses further examined whether these different profiles were associated with different levels of family accommodation and global impairment. LPA identified 5 profiles: SM with No irritability, SM with Low Phasic Irritability, SM with High Phasic Irritability, SM with High Phasic and Moderate Tonic Irritability, and SM with High Phasic and High Tonic Irritability. Patterns of family accommodation and global impairment were highest among youth belonging to profiles characterized by high phasic irritability. Findings highlight separable patterns of irritability across youth with SM, with phasic irritability (i.e., temper outbursts) appearing particularly linked with increased family accommodation and overall global impairment. Assessing phasic irritability is critical for optimizing treatment in youth with SM and can be useful for flagging possible patterns of family accommodation contributing to overall impairment.

Abstract
Over the preceding years, music therapy has gained tremendous attention due to new findings of music in management of various conditions like Alzheimer's, depression, anxiety, insomnia, etc. Music is a non-invasive, patient-friendly and pleasant form of therapy with minimal or no side effects. It activates the reward pathway of brain by influencing several processes such as dopamine release, reduction in cortisol levels, increase in estrogen and testosterone levels. This review article focuses on advantages and disadvantages of music therapy, mechanism of action of music in brain and its effective applications in the management of different diseases. The article covers history of music therapy in America, Egypt, and India with practice of music therapy. The advanced effects of music therapy in autism, cancer, post-operative pain, Parkinson's disease, selective mutism, stroke, heart problems, pregnancy, eating disorders, bone fractures and obsessive compulsive disorders are discussed. Also the effect of music therapy on the quality of sleep and brain waves has been discussed. This is an established profession in western countries like America, UK, Australia, and Canada, but not in low-income countries like India where it needs to be standardized.

Abstract
Selective mutism (SM) is an anxiety disorder in children/adolescents, characterized by the absence of speaking in specific social situations, mostly at school. The selective mutism questionnaire (SMQ) is a parent report, internationally used to assess SM symptomatology and treatment outcomes. Since no assessment instrument for SM was available in the Netherlands, our aim was to investigate the psychometric properties of the Dutch translation of the SMQ, through reliability, confirmatory factor, and ROC analyses conducted on data obtained in 303 children (ages 3-17 years; clinical SM group n = 106, control group n = 197). The SMQ turned out to be highly reliable (α = 0.96 in the combined sample; 0.83 within the clinical group) and followed the expected factor structure. We conclude that the Dutch version of the SMQ is a reliable and valid tool both as a screening and clinical instrument to assess SM in Dutch speaking children.

Abstract
The siblings of children with mental disorders are more likely to experience mental health issues themselves, but there has been a lack of sibling studies on selective mutism (SM). The aim of this population-based study was to use national registers to examine associations between children with SM and diagnoses of various mental disorder in their siblings. All singleton children born in Finland from 1987 to 2009, and diagnosed with SM from 1998 to 2012, were identified from national health registers and matched with four controls by age and sex. Their biological siblings and parents were identified using national registries and the diagnostic information on the siblings of the subjects and controls was obtained. The final analyses comprised 658 children with SM and their 1661 siblings and 2092 controls with 4120 siblings. The analyses were conducted using generalized estimating equations. Mental disorders were more common among the siblings of the children with SM than among the siblings of the controls. The strongest associations were observed for childhood emotional disorders and autism spectrum disorders after the data were adjusted for covariates and comorbid diagnoses among SM subjects. The final model showed associations between SM and a wide range of disorders in siblings, with strongest associations with disorders that usually have their onset during childhood. Our finding showed that SM clustered with other mental disorders in siblings and this requires further research, especially the association between SM and autism spectrum disorders. Strong associations with childhood onset disorders may indicate shared etiologies.

Abstract
INTRODUCTION Selective mutism (SM) is an anxiety disorder categorized by a persistent failure to speak in specific situations. In an attempt to facilitate interaction with individuals with SM, other forms of communication (e.g. computer-mediated communication; CMC) are often tried. However, CMC is understudied in individuals with SM, while, especially since the COVID-19 pandemic, the importance of CMC for education and social purposes only increased. METHODS In this study, we explored CMC in 79 adolescents with either selective mutism (n = 34), or typical development (n = 45). All participants completed a survey concerning verbal and written CMC in three contexts (friends, family, and school). RESULTS Results showed that adolescents with SM used not only verbal but also written CMC less frequently than the comparison group across contexts. While the comparison group preferred Face-to-Face communication over CMC, adolescents with SM were divided, especially in the school context. With family and friends, the majority of the SM group preferred Face-to-Face communication, even though this provoked more feelings of tension than CMC for part of the group. CONCLUSION These findings support anecdotal reports that SM affects not only speech but extends to other communicative venues and includes written communication in many situations. This underlines the importance of addressing not just speaking behavior but also writing and CMC in the diagnostic evaluation and treatment plans for adolescents with SM.

Abstract
Some long-term outcomes for participants with selective mutism (SM) are elevated rates of phobic disorders, particularly social phobia, persistent communicative problems, and reduced self-esteem. However, data on the long-term outcomes of SM are scarce. In this study, by analyzing interpersonal anxiety, communication skills, and self-esteem among those who experienced SM and felt cured (SM-C-group: 30 females, 6 males, mean age 28.0, SD = 7.42, range 19-47 years), those who experienced SM and did not feel cured (SM-NC-group: 37 females, 4 males, mean age 27.4, SD = 7.24, age range 19-50 years), and those who had not experienced SM (Non-SM-group: 30 females, 30 males, mean age 26.4, SD = 7.62, age range: 20-48 years), we examined the long-term outcomes of SM and the factors that influence the feeling of being cured of SM. Results showed that the SM-C-group and SM-NC-groups had significantly higher interpersonal anxiety and significantly lower communication skills than the Non-SM-group. Moreover, the SM-C-group showed significantly lower interpersonal anxiety and significantly higher communication skills than the SM-NC-group. However, while there was no significant difference in self-esteem between the SM-C and SM-NCgroups, there was a significant difference between the SM-NC and Non-SM groups. The SM-C and SM-NC groups did not differ on the retrospective symptom load (SMQ-J), but did on the Current level of difficulty with speaking. The results of the logistic regression analysis predicted that communication skills and self-esteem did not influence the feeling of being cured of SM, but interpersonal anxiety and Current level of difficulty to speak did. Therefore, it is speculated that the intensity of this interpersonal anxiety and whether people with SM still felt difficulty in talking to others may have affected the feeling of being cured from SM.

Abstract
BACKGROUND Selective mutism (SM) is a childhood onset anxiety disorder, and the main symptom is not speaking in certain social situations. Knowledge about the duration and long-term outcomes of SM have been lacking and the aim of this systematic literature review was to address this gap in the literature. We investigated how long SM symptoms persisted as well as other psychiatric outcomes associated with SM in later life. METHODS The PubMed, PsycInfo, Web of Science, Cochrane Library and Embase databases were initially searched from inception to 11 September 2023. Studies were included if they were published in English and had followed up subjects with clinically diagnosed SM for at least two years. The review followed the Preferred Reporting Items of Systematic Reviews and Meta-analyses guidelines and the protocol was registered with the Open Science Framework. The papers were assessed using the Quality Assessment with Diverse Studies tool. RESULTS This review screened 2,432 papers and assessed 18 studies. Seven case series studies were excluded from discussion because of the low number of subjects and the fact that their findings could not be generalized to wider populations. In the end, nine clinical cohorts and two case control studies were reviewed. These provided a total of 292 subjects and the sample sizes ranged from 11-49. The overall quality of the studies was moderate. The review found that 190 of the 243 subjects in the studies that reported recovery rates showed moderate or total improvement from SM during follow up. Other anxiety disorders were the most common psychiatric disorders later in life, although these results should be interpreted with caution. Older age at baseline and parental psychopathology might predict greater impairment, but further studies are needed to confirm these results. CONCLUSIONS Most subjects with SM recovered from this disorder during adolescence, but anxiety disorders were common in later life. Early detection and treatment are needed to prevent symptoms from persisting and other psychiatric disorders from developing.

Abstract
Selective mutism (SM) is an anxiety disorder (prevalence 1-2%), characterized by the consistent absence of speaking in specific situations (e.g., in school), while adequately speaking in other situations (e.g., at home). SM can have a debilitating impact on the psychosocial and academic functioning in childhood. The use of psychometrically sound and cross-culturally valid instruments is urgently needed.The aim of this paper is to identify and review the available assessment instruments for screening or diagnosing the core SM symptomatology. We conducted a systematic search in 6 databases. We identified 1469 studies from the last decade and investigated the measures having been used in a diagnostic assessment of SM. Studies were included if original data on the assessment or treatment of SM were reported. It was found that 38% of published studies on SM reporting original data did not report the use of any standardized or objective measure to investigate the core symptomatology. The results showed that many different questionnaires, interviews and observational instruments were used, many of these only once. The Selective Mutism Questionnaire (SMQ), Anxiety Disorders Interview Schedule (ADIS) and School Speech Questionnaire (SSQ) were used most often. Psychometric data on these instruments are emerging. Beyond these commonly used instruments, more recent developed instruments, such as the Frankfurt Scale of SM (FSSM) and the Teacher Telephone Interview for SM (TTI-SM), are described, as well as several interesting observational measures. The strengths and weaknesses of the instruments are discussed and recommendations are made for their use in clinical practice and research.

Abstract
The present study addressed the different contributors to social anxiety in children with Selective Mutism (SM), with and without co-occurring Autism Spectrum Disorder (ASD) (SM + ASD). Seventy-five parents completed an online composite questionnaire consisting of the symptoms of SM and ASD, anxiety and sensory measures. The results found the SM + ASD group showed significantly higher levels of social anxiety and sensory avoidance compared to the SM only group. However, a simple mediation model revealed sensory avoidance to be a mediator of this relationship between the diagnosis and social anxiety.. Therefore, higher levels of sensory avoidance may help to differentiate social anxiety between the groups and may also be a sign of ASD in children with SM who have and/or are yet to receive an ASD diagnosis.

Abstract
Selective mutism (SM) is a severe but understudied childhood anxiety disorder. Most epidemiological research on SM was conducted decades ago and is limited by small sample sizes. This study analyzes parent-reported clinical data from 230 children with diagnosed and suspected SM to provide current information about the presentation of this disorder. Overall, anxiety and social anxiety symptoms were elevated. Gender ratio, comorbidities and family history of psychopathology were generally aligned with previous research. However, age of onset and diagnosis were both earlier than previously reported, with an average delay of 2 years between onset and diagnosis. The majority of children received therapy and school accommodations for their SM, yet there was large variability in types of interventions. This is the largest survey of children with SM conducted primarily within the US and it constitutes the first systematic inquiry into interventions and accommodations received within clinical and school settings.

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.

Abstract
Selective mutism (SM) and autism frequently co-occur together, exacerbating social communication deficits and associated anxiety. However, professionals have lacked a readiness to diagnose SM and autism together, making the need to understand parental experiences of caring for a child with SM and autism crucial. The current study utilised Interpretative Phenomenological Analysis (IPA) to explore parents' experience of caring for children with SM and autism. Semi-structured interviews were conducted with eleven mothers and one father of children aged between 5 and 18 years. All children were diagnosed with SM and had undertaken, or were currently undertaking, an autism diagnostic process. Analysis of the transcripts resulted in the following themes: Complexities from co-occurring issues; The overwhelming impact of SM; The diagnostic journey; Finding solutions and advocacy. Judgements and minimisation of symptoms from educational and healthcare systems exacerbated delays in diagnosis preventing appropriate intervention. The complexities of caring for a child with SM and autism, alongside wider misunderstandings, exacerbated parental stress, impacting the family. Parental advocacy and safe environments provided opportunities for children to better manage contextually based mutism. Improvements in identification and compassionate understanding from wider systems by involving parents as key stakeholders are essential to improve this situation.

Abstract
A deficit in emotion regulation skills could be an important factor influencing the vulnerability and maintenance of symptoms in selective mutism (SM). Unfortunately, to date only a few studies have examined emotion regulation in SM. Therefore, the present study investigated whether SM is associated with dysfunctional emotion regulation strategies. We compared a sample of 28 children and adolescents with SM (M = 12.66 years, SD = 3.98; 18 females) to 33 controls without SM (M = 12.45 years, SD = 3.18; 21 females). Both groups were investigated for the assessment of SM, social anxiety and emotion regulation using self and parent report questionnaires. We assumed that the disorder is associated with less adaptive and more maladaptive strategies, especially maladaptive cognitive strategies. Instead of significant differences in these overall values, only significant differences in individual emotion regulation strategies were found. In terms of adaptive strategies, children and adolescents with SM reported less problem-oriented behaviour and less cognitive problem-solving. Instead, they reported the maladaptive strategy of abandonment more often than the control group. In contrast to other anxiety disorders, children and adolescents with SM did neither report maladaptive cognitive strategies nor seek support more frequently than the control group. Their emotion regulation strategies are qualitatively closely related to the symptoms of SM, which makes it difficult to determine their independent significance.

Abstract
Selective Mutism (SM) is an anxiety disorder with predictable and circumscribed situations in which children remain silent while they speak unaffectedly in others. However, core features of anxiety inducing stimuli have rarely been studied so far. Parents of children with elevated SM symptomatology participated in an online-based study and answered open ended questions about specific characteristics of a person, place, and activity that elicit failure to speak in their child. The final sample consisted of n = 91 parents with children aged between 3 and 17 years (M = 8.02 years, SD = 3.94). Answers were analyzed by qualitative content analysis. Characteristics of a person were assigned to five categories with lack of distance as the most frequently reported feature. With respect to a place, the majority of parents mentioned unknown places as a silence trigger. The most frequently mentioned feature of an activity that was designated to be associated to silence was new activity. There were only few associations between the designation of these features, age, and gender. For the first time, anxiety inducing triggers related to person, place, and activity were comprehensively assessed in children with SM. This allows a differentiated and deeper understanding of an understudied disorder. The majority of characteristics can be associated with proposed etiological factors such as increased behavioral inhibition, conditioning processes, social anxiety, and a strong need for control. Implications for effective treatments are discussed.

Child Adolesc Psychiatry Ment Health 2021; 15:81.

Abstract
BACKGROUND Selective mutism (SM) has been conceptualized as an extreme variant of social anxiety disorder (SAD), in which the failure to speak functions as an avoidance mechanism leading to a reduction of intense fear arousal. However, psychophysiological studies in children with SM are scarce and physiological mechanisms underlying the failure to speak are largely unknown. In contrast, children with SAD are characterized by a combination of a chronically elevated physiological arousal and a blunted physiological fear response to social stress. Due to the large overlap between SM and SAD, similar mechanisms might apply to both disorders, while differences might explain why children with SM fail to speak. The aim of our study is to investigate psychophysiological mechanisms of the failure to speak in children with SM. METHODS We assessed in a total of N = 96 children [8-12 years, SM: n = 31, SAD: n = 32, typical development (TD): n = 33] resting baseline arousal in absence of social threat and the course of physiological fear response in two social stress paradigms, differing in terms of whether the children are expected to speak (verbal task) or not (nonverbal task). RESULTS Children with SM were characterized by increased tonic arousal compared to the other two groups, and by a more inflexible stress response in the nonverbal but not in the verbal task compared to TD-children. Further analyses revealed that children with SM who did not speak during the verbal task already demonstrated reduced arousal in anticipation of the verbal task. CONCLUSION The increased tonic arousal generalized to non-social situations in SM could indicate a long-term alteration of the autonomic nervous system. Furthermore, the differential physiological stress response may indicate that silence acts as a maladaptive compensatory mechanism reducing stress in verbal social situations, which does not function in nonverbal situations. Our findings support the idea that the failure to speak might function as an avoidance mechanism, which is already active in anticipation of a verbal situation. Treatment of SM should take into account that children with SM may suffer from chronically elevated stress levels and that different mechanisms might operate in verbal and nonverbal social situations.

Abstract
AIM We describe the difficulties encountered in making a diagnosis where a somatic condition manifests itself alongside psychiatric symptoms associated with possible psychiatric comorbidities. METHODS A case study is presented of a 15-year-old girl who was eventually diagnosed with ornithine transcarbamylase (OTC) deficiency (hyperammonaemia type II), following an initial diagnosis of pervasive developmental disorder, selective mutism, and anorexia nervosa. RESULTS The OTC disease is not fully expressed in females and its prevalence is lower than in males. Around 17-20% of female patients found with a defective OTC gene on an X chromosome can suffer from OTC deficiency that may result in elevated levels of ammonia in the blood; this occurs when one of the X chromosomes become inactivated. Patients typically present with nausea, migraines, and a history of dietary protein avoidance. In more severe cases, ataxia, confusion, hallucinations, and cerebral oedema can occur. The OTC deficiency can thus remain undiagnosed in women for many years. CONCLUSION Somatic comorbidity in psychiatric inpatients is commonly found; however, such disorders are rarely diagnosed or even treated adequately.

Abstract
The study presented in the following verifies some assumptions of the novel 'unsafe world' model of selective mutism (SM). According to this model, SM is a stress reaction to situations erroneously experienced via cognition without awareness as 'unsafe'. It assumes a high sensitivity to unsafety, whereby the nervous system triggers dissociation or freeze mode at relatively low thresholds. We examine whether there is a correlation between SM, sensory-processing sensitivity and dissociation. We compared a sample of 28 children and adolescents with SM (mean age 12.66 years; 18 females) to 33 controls without SM (mean age 12.45 years; 21 females). Both groups were compared using a medical history sheet, the 'Selective Mutism Questionnaire' (SMQ), a 'Checklist for Speaking Behaviour' (CheckS), the 'Highly Sensitive Person Scale' (HSPS), the 'Child Dissociative Checklist' (CDC), the 'Adolescent Dissociative Experience Scale' (A-DES) and the 'Social Phobia and Anxiety Inventory for Children' (SPAIK). Appropriate parametric and non-parametric tests were conducted to examine differences between groups. The results indicate that sensory-processing sensitivity was significantly higher in the group of children and adolescents with SM [X2(1) = 7.224, p = 0.0007; d = 1.092]. Furthermore, dissociative symptoms were more common in children and adolescents with SM than in controls [F(1, 33) = 13.004, p = 0.001; d = 0.986]. The results indicate that sensory-processing sensitivity and dissociation are important factors of SM that may hold important implications for the treatment.

Abstract
Selective mutism (SM) is an anxiety disorder in which a child fails to speak in some situations (e.g., school) despite the ability to speak in other situations (e.g., home). Some work has conceptualized SM as a variant of social anxiety disorder (SAD) characterized by higher levels of social anxiety. Here, we empirically tested this hypothesis to see whether there were differences in social anxiety (SA) between SM and SAD across behavioral, psychophysiological, self-, parent-, and teacher-report measures. Participants included 158 children (Mage = 8.76 years, SD = 3.23) who were classified into three groups: children with SM and who were also highly socially anxious (SM + HSA; n = 48), highly socially anxious children without SM (HSA; n = 48), and control children (n = 62). Children participated in a videotaped self-presentation task, following which observed SA behaviors were coded, and salivary cortisol reactivity was measured. We also collected child, parent, and teacher reports of children's trait SA symptoms. The SM + HSA and HSA groups had similar observed non-verbal SA behavior, cortisol reactivity, and trait SA symptom levels according to parent and child reports, but SM + HSA children had significantly higher SA according to teacher report and observer-rated verbal SA behavior relative to the HSA group. As expected, control children had lower cortisol reactivity and SA across all measures relative to the other groups. Although SM and SAD in children share many similarities, SM may be characterized by greater SA in certain social contexts (e.g., school) and is distinguishable from SAD on behavioral measures of verbal SA.

Abstract
The core symptom of the anxiety disorder selective mutism (SM) is absence of speech in specific situations, such as at school. The most commonly used standardized instruments to assess speaking behavior are the parent-rated Selective Mutism Questionnaire (SMQ) and the teacher-rated School Speech Questionnaire (SSQ), scored from 0 to 3, indicating that speaking behavior never, seldom, often, and always occur. They were developed to assess severity of mutism and potential effects of treatment. However, prospective data on speaking behavior in typically developing children (TDs) are missing in the literature. The main aim of this study was to present data from TDs over time with previously reported data from children treated for SM, as a comparison. Participants were 64 children aged 3-9 years, 32 TDs who were a matched control group to 32 children with SM. At baseline, the mean SMQ and SSQ scores were ⩾2.5 in TDs and 0.5 in children with SM. The TDs did not show significant changes over time, while significantly increased speech was found in children with SM after treatment. Thus, our findings support the use of the SMQ/SSQ to assess baseline SM severity and to evaluate potential treatment effects in future studies.

Abstract
Selective mutism (SM) is a relatively rare anxiety disorder, characterized by a child's consistent failure to speak in various specific social situations (e.g., at school), while being able to speak in other situations (e.g., at home). Prevalence rates vary from 0.2% to 1.9%. SM is usually identified between the ages of 3-5 years. It is often underdiagnosed and consequently children receive no or inadequate treatment, with negative consequences for school and social functioning. If left untreated, SM can result in complex, chronic anxiety and/or mood disorders in adolescence and impaired working careers in adulthood. Currently, no evidence-based treatment for SM is available in the Netherlands, therefore this study aims to [1] test the effectiveness of a treatment protocol for SM that is carried out at school, and to [2] identify baseline predictors for treatment success. This article presents the design of a randomized controlled trial into the effectiveness of a behavioral therapeutic protocol for selective mutism in children (age 3-18). The expected study population is n = 76. Results of the treatment group (n = 38) will be compared with those of a waiting list control group (WCG) (n = 38). Pre and post treatment assessments will be conducted at comparable moments in both groups, with baseline assessment at intake, the second assessment at 12 weeks and post-assessment at the end of treatment. If proven effective, we aim to structurally implement this protocol as evidence-based treatment for SM.
