Clinical Trial Summary

Children born with a cleft lip and palate (CLP) are known to be at risk for speech-language disorders that impact academic and social emotional growth. Even at very young ages (<3 years), speech-language disorders are already observed. It is hypothesized that speech-language intervention delivered before the age of 3 years old could decrease the impact of CLP on speech-language development. This would result in a decreased need for speech-language therapy on the long-term and a reduced burden of care on children, families and health services. However, no evidence is yet available to support any specific model of early speech-language intervention in this population. Consequently, no standardized clinical practice guidelines are available yet. Symbolic gesture training in combination with verbal input expands the natural communication of young children including multimodal speech-language input (i.e., verbal and manual input) via caregivers who act as co-therapists. To contribute to the evidence-based practice in the field of cleft speech therapy, this research project aims to determine the effectiveness and feasibility of symbolic gesture training in one-year old children with CLP by comparing different intervention approaches based on perceptual, psychosocial and qualitative outcome measures.


Description:

Children with CP±L are known to be at risk for speech-language delays that impact educational and social-emotional growth. Early intervention in this population mostly focuses on improving verbal input via caregivers or professionals without including a multimodal language input. As stated above, no evidence is yet available for the effectiveness and feasibility of early intervention based on symbolic gesture training in combination with verbal input to improve speech-language skills in young children with CP±L. To contribute to the evidence-based practice in the field of early cleft palate speech intervention, this research project will focus on the effectiveness of symbolic gesture training in one-year old children with CP±L by comparing different intervention approaches based on quantitative and qualitative outcome measures. This project meets the need to evaluate the impact of early intervention on speech-language outcomes in children with CP±L as proposed by several researchers based on reviews regarding this topic. The primary objective is to explore if children with CP±L who are enrolled in symbolic gesture training to support verbal in- and output at the age of 12 months have increased receptive and expressive language skills compared to children with CP±L who are enrolled in verbal training or not involved in any intervention at all. The secondary objectives are: 2.1 To explore if children with CP±L who are enrolled in symbolic gesture training at the age of 12 months have improved speech skills, compared to children with CP±L who are enrolled in verbal training or not involved in any intervention at all; 2.2 To explore if children with CP±L who are enrolled in symbolic gesture training at the age of 12 months demonstrate more gesture use, compared to children with CP±L who are enrolled in verbal training or not involved in any intervention at all; 2.3 To explore if caregivers of children with CP±L who are enrolled in symbolic gesture training when their child is 12 months of age provide more frequent and more complex linguistic input to their child's utterances compared to caregivers of children with CP±L who are enrolled in verbal training or not involved in any intervention at all.

Intervention

Behavioral:
Infant sign training
Training session 1: Information is given about what infant signs are, how they originated, how speech and (gestural) language develop in young children with CP ± L, the possible advantages of using infant signs and tips for success. Twelve signs are chosen to start with: six narrative signs (mostly object concepts) and six steering signs (mostly non-object concepts). Training session 2: Experiences with using infant signs at home are shared, repetition of the 12 infant signs and tips for success are discussed. Another 12 signs are chosen to add to the repertoire the caregivers can use, based on caregiver input. Training session 3: The same as training session 2. The content is based on the input the caregivers experience. Another 12 signs are chosen to add to the repertoire the caregivers can use, based on caregiver input. Reading aloud while using infant signs is shown and practiced.
Verbal training
Training session 1: Information is given about how speech and language develop in young children with CP ± L and how caregivers can support their child during this development Tips for success and suggestions on how to use these supportive verbal techniques at home are discussed. Training session 2: Experiences with using supportive verbal techniques at home are shared and supportive verbal techniques repeated. Information is provided about how children learn new words and tips for success are expanded. Training session 3: The same as training session 2. The content is based on the input the caregivers experience. Additionally, advances of reading aloud are discussed and reading aloud is practiced.

Outcome

Type Measure Description Time frame Safety issue
Primary Receptive language level based on language test To verify the receptive language level, the Dutch Nonspeech Test will be used at T0 and T1. This standardized test observes, scores and judges communication conditions and first verbal and non-verbal communication in the age range of 12 to 21 months. At T2, the Schlichting Test of Language Comprehension and Language Production will be used. This standardized test measures receptive and expressive language development starting from 24 months of age.
This outcome measure will be expressed in percentiles.
12 months
Primary Expressive language level based on language test To verify the expressive language level, the Dutch Nonspeech Test will be used at T0 and T1. This standardized test observes, scores and judges communication conditions and first verbal and non-verbal communication in the age range of 12 to 21 months. At T2, the Schlichting Test of Language Comprehension and Language Production will be used. This standardized test measures receptive and expressive language development starting from 24 months of age.
This outcome measure will be expressed in percentiles.
12 months
Primary Total language level based on caregiver report Caregivers will complete the Dutch version of the MacArthur Communicative Development Inventory, 'words and signs' (T0 and T1) or 'words and sentences' (T2). These standardized questionnaires evaluate word comprehension and production, the use of signs by the child, and grammatical development.
This outcome measure will be expressed in percentiles.
12 months
Secondary Communicative acts produced by the child The communicative acts of the child will be analyzed based on a video recording of 30 minutes free play with four standardized toy sets (i.e., a farm, a house, cutlery, and vehicles) between the child and caregiver at T0, T1 and T2. Each potential communicative act of the child will be annotated by the means of communication (eye contact, gesture or vocalization; vocalization will be identified as non-canonical, canonical or word).
This outcome measure will be expressed in the total number of communicative acts produced by the child.
12 months
Secondary Communicative acts produced by the caregiver The communicative acts of the caregiver will be analyzed based on a video recording of 30 minutes free play with four standardized toy sets (i.e., a farm, a house, cutlery, and vehicles) between the child and caregiver at T0, T1 and T2. Each potential communicative act of the caregiver will be annotated by the means of communication (eye contact, gesture or vocalization).
This outcome measure will be expressed in the total number of communicative acts produced by the caregiver.
