About this study

Official title: A Psychometric Questionnaire Study With a Control Group Design of Children and Young People With Selective Mutism, as Well as on Adults Who Suffered Selective Mutism Earlier in Life

The study's goal is to check and verify basic assumptions of a new selective mutism developmental model from Melfsen and Walitza through standardized and routinely used patient questionnaires. The primary emphasis is the question of a connection between selective mutism and high sensitivity, dissociation, emotional regulation, family structure, social anxiety and self-esteem.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Psychometric questionnaire studyBehavioural

    Four groups participate in the psychometric questionnaire study. A group of mute children and their mothers (EG:A), as well as a normal, healthy control group (KG:A) with roughly the same age and sex characteristics fill out one-time questionnaires about current daily life experiences. In addition, another group of formerly mute adults (EG:B) as well as a comparable age/sex normal control group will be retrospectively questioned using the same specifically tailored questionnaire.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Symptoms severity of selective mutism

    The parent report "Selective Mutism Questionnaire (SMQ)" is a 17-item parent-rating measure designed to assess the severity of selective mutism. The test uses a 4-point scale to rate the frequency of the child's speaking behaviour in school (6 items), home/family (6 items) and public settings outside school (5 items) from 0 (never) to 3 (always) each, with a total score of 51. Higher score means a worse outcome.

    Measured: 24 months

  2. High sensitivity

    The "Highly Sensitive Person Scale" (HSP) is a self-report questionnaire with 27 items to be answered on a seven-point Likert scale (from 1 "not at all" to 7 "absolutely"). The total score divided by item number ranges from 0 to 7. Higher score means a worse outcome.

    Measured: 24 months

  3. Family relation structure

    The "Parent-Image-Questionnaire for Children and Adolescents (EBF-KJ)" is a self-reporting questionnaire for children and adolescents to record the family relationship structure with 36 items on a five-point Likert scale from 0 (never) to 4 (always). Higher score means a stronger characteristic.

    Measured: 24 months

  4. Emotion regulation

    Emotion regulation is measured using the German questionnaire "Fragebogen zur Erhebung der Emotionsregulation bei Kindern und Jugendlichen (FEEL-KJ). It is a multi-dimensional tool for the emotion-specific detection of emotion regulation strategies. It measures fear, sadness and anger. Adaptive strategies include problem-oriented behavior, dispersion, mood elevation, acceptance, forgetting, revaluation and cognitive problem solving. Maladaptive strategies include abandonment, aggressive behavior, withdrawal, self-devaluation and perseveration. A total of 90 items is to be rated on the basis of a five-level rating scale with regard to their frequency. Higher scores mean more adaptive or maladaptive strategies.

    Measured: 24 months

  5. Symptoms of selective mutism

    Symptom severity is assessed by using the "Checklist for speaking behaviour, parent report" (CheckS). It assesses the communicative burden of various socially interactive situations for children suffering from selective mutism on a five-point scale (from 0 = "never" to 4 = "always"). A distinction is made between different contexts, namely the persons to be spoken to, the type of communication, the length of the spoken answers, the conversational situations, the contents of the conversation, the places and surroundings, the expectations of those present and the unpredictability of contexts. The total score ranges from 0 to 4.Higher score means a worse outcome.

    Measured: 24 months

  6. Dissociation

    The German translation of the "Child Dissociative Checklist" (CDC) is a parent report of 20 items using a three-point Likert scale (0 = "very true", 1 ="somewhat true", 2 ="not true"). Parents are asked to report dissociative behavioural problems of their child within the past 12 months. Higher score means a worse outcome.

    Measured: 24 months

  7. Dissociation

    The children and adolescents completed the "Self-Perception Questionnaire for Children and Adolescents" (A-DES) to assess dissociative symptoms. 30 items are to be assessed on an 11-point rating scale (from 0 = "never" to 10 = "always") in terms of their frequency. Higher score means a worse outcome.

    Measured: 24 months

  8. Social anxiety

    The German version of the "Social phobia and anxiety inventory for children (SPAIK) is used to asses social anxiety in children and adolescents. The questionnaire consists of 26 situations assessing somatic, cognitive and behavioural aspects of social anxiety. They measure characteristic aspects of social anxiety on a three-point Likert scale (from 0 = "never or seldom" to 3 = "most of the time or always") with a total score of 52. Higher score means a worse outcome.

    Measured: 24 months

  9. Self-esteem

    The "List of statements on self-esteem for children and adolescents" (ALS) uses the same 18 items to differentiate the self-esteem of children and adolescents in three areas: family, school and leisure. Higher score means a stronger self-esteem.

    Measured: 24 months

Where is the study taking place?

The record lists 1 site in Switzerland. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Symptoms severity of selective mutism (time frame: 24 months). The study lists 9 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04233905, which also lists 2 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 Jan 2020.
