Brief Summary

Autism spectrum disorders (ASD) are disabling and impairing conditions affecting 1% of children in Norway. ASD is hallmarked by severe social deficit and lack of independence causing reliance on supportive systems throughout life. Parents are usually the primary caretakers and support, often throughout life. Normal parenting skills are however often ineffective due to the social dysfunction of the child with ASD. This causes high stress as the demands exceed the resources and capability of the parent. The high stress is associated to increased risk for mental health problems, divorce, unemployment and reduced quality of life. High parent stress may also reduce the effect of interventions in ASD. However, although the need is great and parental follow-up is an integral part of health care for ASD children, there is a lack of evidence for such interventions.

The current project aims to evaluate a specific parent program that is in clinical use - the Incredible Years for children with ASD - compared with a standardised treatment as usual (TAU) composed of clinical parent workshops ("first aid for parents").

The aim is to evaluate parenting interventions and promote evidence-based practice in a clinical setting. The investigators will perform a randomized controlled trial and qualitative interviews to compare the effectiveness of treatment as usual (TAU) versus a manualized parent program (IY-ASLD). The study aims to investigate if the parental program may reduce parent stress and improve parental competence and self-efficacy. Secondary goals are to investigate whether the parent program may improve quality of life for the parent and the child and have an impact on long-term child functioning and service use.

Detailed Description

Parental psychoeducation is an integral and intuitive part of health care for children with autism, but there is a lack of evidence for such interventions in general and for parental programs specifically. Studies are usually few and of poor methodological quality. Proper evaluation of parental programs is time and resource consuming. Being able to provide evidence-based parent programs is nevertheless paramount to clinical follow-up, as parents are the most crucial person in a child's life. Efficient parent programs could potentially have enormous downstream beneficial effects, as there is evidence that developmental social pragmatic treatment for parents may improve the child's functioning, but it is currently little known what kind of parent programs should be administered to whom, to what extent or in what form. Many different types of programs exist and there are some indications of what components are necessary for effect. One of the few manualized parent programs for ASD that are available in Norwegian services is the Incredible Years Autism Spectrum and Language Delay Programme (IY-ASLD©). The current project has brought together three Norwegian clinics using the IY-ASLD© to perform a multi-center RCT study. The aim is to evaluate parenting intervention in the early years for families and children with ASD.

The project hypothesizes that empowering parents to be efficient in their role as parents for children with ASD will have both short-term and long-term gains:

Short-term:

1. Improved parental stress and health

2. Improved parental competence and self-efficacy

3. Improved quality of life (QoL) for parents

4. Improved quality of life (QoL) for children

Long-term:

1. Improved child functioning

2. Reduced health service use.

3. Reduced use of alternative treatments

4. Mitigation of long-term adverse effects and disability

Main aim and primary outcome:

To evaluate the effectiveness of the IY-ASLD© vs. the TAU parenting interventions for improving primary outcome measures of lowering parental stress.

Specific hypotheses, research questions and secondary outcomes:

1. Parents in the IY-ASLD© groups will show significant improvement in a) PSI, b) paediatric quality of life and c) parent sense of competence compared with the TAU groups.

2. Children in the IY-ASLD© groups will improve more than in the TAU condition over time, with better long-term child functioning and reduced service use at 12 and 24 months.

3. To understand the subjective experiences of the parents. What are the main needs and how can and does the intervention meet these needs in the respective conditions?

4. What works for whom? Are there important moderators of effect or lack thereof? Is the child's level of functioning or level of ASD symptoms important for the effect of the intervention? Are some parental needs better met by one of the two programs?

Study design, methodology and analytic plan:

The study is planned as a multi-center RCT with a two-year follow-up. ASD is characterized by large heterogeneity and clinical complexity. Furthermore, the literature indicates there is a need for assessing and understanding the long-term effects of the intervention. These factors warrant an RCT design with long-term follow-up. As previous minor studies have all concluded that larger studies are necessary, the multi-center design is necessary to recruit the large number of families needed.

The project is planning to include minimum two PhD candidates. The first PhD project (application at NTNU pending) will focus on the baseline situation for Norwegian parents of children with ASD, using a mixed-methods approach to describe the population and validate the instruments for Norwegian use. Although the PSI, the PSOC and the PedsQL have all been used in Norway, there are no studies published on these instruments for the ASD pediatric population from Scandinavia. The qualitative interviews in the study will examine the subjective experience of the interventions, using a mixed methods approach.

The second PhD project will evaluate the effect of the intervention at T1 and T2 using the PSI as the main outcome measure (T1 and T2) as well as child outcome (PedsQL at T1 and T2, VABS at T2). Parent socio-economic status and parent competence (PSOC) as well as child function and level of ASD will be explored as mediator and moderating variables and/or covariates using structural equation modelling (SEM).

Sample size and power calculations:

Based on power calculations with statistical power of 0.8, a medium effect size (d = 0.5) and α=0.05, a sample size of minimum 64 families per condition, in total 128 families is required. Based on experience from autism follow-up in the clinic it is allowed for a drop-out rate of 20-30% and a two-parent participation rate of 80%. To allow for similar drop-out of 20-30% longitudinally and maintain power at follow up, the project aims to include 240 families. Including three sites aiming for six active condition groups over four years, the project will include an estimated number of 120 families/condition, and approximately 300-400 parental questionnaires (including PSI as the main outcome). This will allow for detection of smaller effect sizes as well as performing analyses of secondary outcomes as well as of mediating and moderating variables.

Recruitment and randomization:

During assessment of the child to determine the presence of autism, parents are interviewed at length using structured interviews. During the later feedback of the assessment to parents, the clinician at the participating sites will inform eligible parents about the project orally and in print. Information about the project will also be presented at parent organization sites, flyers and in the participating clinics. The information catalogue will also mention the project and there will be information about the project in the course catalogue at the basic parent diagnostic course.

Interested parents will be asked to register their contact details in a webtool (SurveyXact) or through direct contact/postal mail. They will be sent detailed information about the project by postal mail/e-mail (depending on their preference) and informed consent to read and sign the informed consent at their leisure.

The three participating clinics diagnose and/or treat 220-270 children with ASD every year, ensuring a large pool of families eligible for inclusion. Immigrant families are frequent in this patient group, and some of these families will thus not be eligible due to language barriers. Each clinic will run 1 or 2 IY-ASLD groups each year with the TAU condition in parallel. When 12-16 families have been recruited at a particular site, randomization to IY-ASLD© or standardized TAU will be performed.

The Incredible Years for Autism Spectrum and Language Delays program - experimental condition

The IY-ASDL program consists of 13 2 hours weekly sessions with small groups of parents of 5-7 children. The program works interactively within the parent group with video vignettes, group discussions and homework assignments between sessions to teach developmentally adapted social interaction and communication based on the child's preferences and needs.

First Aid for Parents - active control condition

The TAU condition is a three-day seminar/work-shop program, building on the content of workshops that are held at HUS as part of the regular clinical follow-up. The workshops will include communication skills, psychoeducation and approaches to daily challenges of nutrition, sleep, hygiene and daily living skills. The workshops given at HUS will be assembled and compressed to a three-day introduction program labelled "Førstehjelpen for Foreldre" (FFF; First aid for Parents). The workshops will be held once a month in the same semester as the local IY-ASDL group to ensure similar treatment periods and time from randomization and follow-up. HUS will be responsible for the development of the content and course materials for the FFF, and will also hold the program at Helse Fonna and SOH, as well as train local clinicians to hold the workshops to ensure fidelity.

User participation:

The project has involved Elisabeth Johansen from the parent organization "Autismeforeningen", from the regional "Hordaland" unit. She is a parent and as representative of the Autismeforeningen, she is in touch with many parents in different stages of their parenting.

The project is targeting user participation by design. The user feedback and evaluation of the project is essential for the delivery. Understanding the effect and experience of the parent program is part of the main outcomes of the project. Qualitative interviews with parents are part of the methodology. This part of the project is crucial to be able to go beyond the measured outcomes of the project to indicate what treatment should be offered to whom. Experiences from parents will inform future service provision to parents of children with autism.

Ethics:

The project has Regional Ethics Committee approval, nr. 188940. An important ethical challenge is the large discrepancy by the perceived need of families with children with ASD and the resources allocated to follow-up. The project aims to contribute to building better-resourced and evidenced-based care for all families living with ASD.
