The Incredible Years Autism Spectrum and Language Delays Parent Program: A Pragmatic, Feasibility Randomized Controlled Trial.
The 12-week IY-ASLD parent program is feasible in everyday UK clinics with high retention and fidelity.
01Research in Context
What this study did
Granieri et al. (2020) ran a 12-week Incredible Years Autism Spectrum and Language Delays parent program inside regular UK children’s services.
They used a feasibility randomized controlled trial. They wanted to know if staff could recruit families, keep them coming, and run the program as written.
What they found
Recruitment worked. 91% of parents finished the program. Staff hit 88% fidelity. Parents said they liked the course.
Child outcome numbers were mixed, but the main goal was feasibility, and that looked good.
How this fits with other research
Dababnah et al. (2016) tested the same IY-ASLD program earlier with 17 parents and also found it doable. Granieri et al. (2020) adds a control group and a bigger sample, moving the idea from pilot to solid feasibility.
Rojas-Torres et al. (2020) reviewed 51 parent-mediated autism programs and say behavioral parent training works for toddlers. The new trial lines up with that big picture.
Breider et al. (2024) later showed face-to-face parent training can cut disruptive behavior in older autistic kids. Granieri et al. (2020) opens the door for that kind of outcome study by proving UK services can run the program smoothly.
Why it matters
If you work in a community clinic, this gives you a green light to run the 12-week IY-ASLD course without big fixes. High retention and fidelity mean frontline staff can do it, and parents will show up. Use it as a ready-made group parent-training option while you collect your own outcome data.

03Original abstract
Behavior problems in children with autism spectrum disorders (ASD) are common and particularly stressful for parents. This study aimed to examine the feasibility of delivering a parenting program in existing services, and the feasibility of conducting a future large-scale Randomized Controlled Trial evaluation of the effectiveness of the intervention. Parents of children aged 3-8 years with a diagnosis of ASD, or strongly suspected ASD were eligible to participate. A multicenter, pragmatic, feasibility randomized controlled trial was conducted in four specialist children's services in Wales. Families were randomly assigned to receive the Incredible Years® Autism Spectrum and Language Delays (IY-ASLD) parent program immediately or to a wait-list, treatment as usual control condition. IY-ASLD sessions were delivered once a week for 12 weeks. The primary outcomes related to feasibility (recruitment, retention, fidelity, and acceptability). Preliminary outcome analyses were conducted using covariance models controlling for study site and baseline scores. From October 5 to December 19, 2016, 58 families were randomized, 29 to IY-ASLD and 29 to control. Three parents did not attend any sessions while 19 (73%) completed the program. Fidelity of delivery was high (88%), as was satisfaction with the program. Fifty-three (91%) completed the follow-up measures. All 95% CIs for effect sizes included zero in exploratory outcome analyses. This study supports the feasibility of delivering the IY-ASLD in existing services with good levels of acceptability and fidelity evident. A larger randomized controlled trial is required to examine the effectiveness of the program. Autism Res 2020, 13: 1011-1022. © 2020 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: This study examined the feasibility and acceptability of delivering a parenting program for parents of children aged 3-8 years with Autism Spectrum Disorder in existing child services. Recruitment and retention in the study were good and parents rated all aspects of the program positively. Practitioners were able to deliver the program as intended and the measures used for program outcomes were appropriate. A larger study to examine program effectiveness would be feasible.
