NCT06125093

Brief Summary

The GAP study is a randomized controlled trial that aims to determine the feasibility and efficacy of the "Incredible Years Autism Spectrum and Language Delays" (IY-ASLD®) intervention for families of children with developmental problems from a genetic basis. It is a multicentric trial where families will randomly be assigned to the intervention group or to a control group (they will follow their usual treatment). The intervention will be carried out in an online format, and it will involve 22 weekly group sessions. The results of The GAP study will help clinicians and policy makers in guiding towards evidence-based treatment options for these particularly vulnerable group of infants.

Outcome Measures

Primary Outcomes (4)

  • Percentage of parents engaging with and finishing the program

    Parents' attendance at the sessions will be regeristered weekly with a sheet of attendance, with the aim to determine levels of compliance and engagement with the intervention. An attendance of at least 15/22 sessions is expected, with a minimum of 50% of parents finishing the program.

    Attendance sheet completed weekly throughout treatment (22 weeks total)

  • Compliance and satisfaction throughout the study (Autism Program Parent Weekly Evaluation)

    Parents' compliance and satisfaction with the intervention will be assessed weekly after each session with the questionnaire "Autism Program Parent Weekly Evaluation", which is part of the IY-ASLD® program materials.

    Questionnaire administered to the intervention group weekly throughout treatment (22 weeks total)

  • Parents' acceptability and satisfaction with the program (evaluated with the Autism Program Parent Final Satisfaction Questionnaire)

    Parents' acceptability and satisfaction with the program will be assessed with the Autism Program Parent Final Satisfaction Questionnaire (included within the IY-ASLD® program). Data will be collected after the last session of the intervention.

    Administered to the intervention group at treatment completion (approximately 22 weeks after baseline)

  • Parents' overall experiences with the program (evaluated with individual interviews)

    Individual interviews will be conducted after the last session of the intervention to explore from a qualitative perspective: (1) parents' acceptability, satisfaction and overall experience with the intervention, and (2) parents' perceived changes in their parenting skills and parental distress after the intervention. Outcome measurements 3 and 4 will be combined to determine parents' experiences, acceptability and satisfaction with the program.

    Interviews to the participants of the intervention group at treatment completion (approximately 22 weeks after baseline)

Secondary Outcomes (5)

  • Changes from baseline to post-intervention in Parent Stress Inventory-Short Form (PSI-SF)

    Administered to the intervention and control group at baseline (prior to programme initiation) and at immediately after the intervention (approximately 22 weeks after baseline)

  • Changes from baseline to post-intervention in Alabama Parenting Questionnaire-Preschool revision (APQ-Pr)

    Administered to the intervention and control group at baseline (prior to programme initiation) and at immediately after the intervention (approximately 22 weeks after baseline)

  • Changes from baseline to post-intervention in Beck Depression Inventory (BDI)

    Administered to the intervention and control group at baseline (prior to programme initiation) and at immediately after the intervention (approximately 22 weeks after baseline)

  • Changes from baseline to post-intervention in Autism-Specific Five Minute Speech Sample (ASFMFSS)

    Administered to the intervention and control group at baseline (prior to programme initiation) and at immediately after the intervention (approximately 22 weeks after baseline)

  • Clinicians' experiences with the intervention delivered

    Interviews to clinicians at treatment completion (approximately 22 weeks after baseline)

Study Arms (2)

Intervention group

EXPERIMENTAL

Those in the intervention group will participate in a weekly group-based online intervention for approximately 6 months (Incredible Years-Autism Spectrum and Language Delays Parent Program, IY-ASLD®). Families allocated to the intervention group will also receive treatment as usual (TAU).

Behavioral: Incredible Years Autism Spectrum and Language Delays Parent Program (IY-ASLD®)

Treatment as usual (TAU) group

NO INTERVENTION

The TAU condition involves outpatient appointments with different paediatric specialists in the hospitals of the 3 sites of the study. Depending on the patients' needs, some cases will be assisted in early years centers or child mental health centers based in the community.

Interventions

The IY-ASLD® program is a weekly group-based intervention for parents of children presenting neurodevelopmental problems (ASD symptoms, communication or language difficulties). The group is formed by 6-10 parents, and it is led by a group leader and a co-therapist, trained in the model. The intervention is manualized. It includes video modelling and emphasizes the importance of practice-based learning through role-playing. The IY-ASLD® program takes into consideration the different developmental levels of each child and pairs parents according to this variable in role-play and other one-to-one discussions. Weekly home tasks will be assigned to parents, and families will be phoned each week to encourage home-based practice. The intervention will be conducted online. Even though the IY-ASLD® original intervention comprises 14 sessions, the online format requires 22 weekly sessions. Fidelity to the intervention will be assessed in accordance with the regulations of the program.
