ENabling parents of preschool children with Autism spectrum disorders: A study protocol for a multi- centre randomised Controlled Trial of parenting programs (ENACT)

Imagine the world of child development as a vast, bustling construction site. Sometimes, the blueprints for how a child interacts with the world look a little different than the standard plans; this is what doctors call Autism Spectrum Disorder (ASD). While the child is busy building their own unique structure, the parents are the foremen, constantly trying to understand the new plans, manage the materials, and keep the project moving forward. It's a job that can be incredibly stressful, exhausting, and sometimes feel like you're trying to build a skyscraper with a hammer meant for a birdhouse. For years, scientists have known that when parents feel overwhelmed, it can make the whole construction project harder. But here's the big question: What if we could give the foremen a better toolkit? What if we could teach them specific, proven ways to help their child's construction go smoother, while also making sure the foremen don't burn out? This is the corner of science this paper lives in: testing whether specific training programs for parents can actually reduce stress and improve life for families raising children with autism.

The paper you're about to read is the "blueprint" for a massive experiment called ENACT. It's important to know right away that this isn't a report on what the experiment found yet; it's the detailed plan for how they are going to find out. Think of it as the recipe before the cake is baked. The researchers are setting up a giant, multi-city race to see which "parenting training" works best. They are comparing two different approaches. The first is a fancy, high-tech toolkit called the "Incredible Years" program, which teaches parents specific games and strategies to boost their child's communication and behavior. The second is a "standard first-aid kit," a simpler, three-day course that covers the basics of daily life challenges like sleep and eating. The goal is to see if the fancy toolkit is worth the extra effort compared to the standard kit, or if the standard kit is actually just as good.

Here is the story of the ENACT study, the plan to solve the puzzle of the best way to help parents.

The Big Question: Do We Need a Master Class or Just a Quick Guide?
The researchers are asking a simple but huge question: When parents of preschoolers (ages 2 to 6) with autism need help, is it better to give them a deep, 13-week course that teaches them how to be a "coach" for their child, or is a shorter, 3-day "first aid" course enough?

In Norway, where this study is happening, the government says parents must get some kind of support. But right now, that support is a bit like a buffet where every restaurant serves a different dish. Some parents get a great meal, others get a snack, and no one is really sure which one fills them up best. This study wants to fix that buffet. They want to know if the "Incredible Years" program (the fancy toolkit) is actually better at reducing parent stress and helping the child than the standard "First Aid for Parents" course.

The Race: How the Study is Set Up
Imagine four different stadiums across Norway: Bergen, Haugesund, Trondheim, and Tromsø. In each stadium, there are families waiting to join the race. The researchers are looking for about 240 families in total.

Here is how the race works:

1. The Start Line: A family signs up. They fill out a bunch of questionnaires about how stressed they are, how good they feel at parenting, and how their child is doing. This is the "before" picture.
2. The Coin Flip: The family is randomly assigned to one of two teams. It's like flipping a coin.
   • Team A (The Incredible Years): These parents go to 13 weekly group meetings. Each meeting is 2.5 hours long. They watch videos, play games, and learn specific tricks to help their child talk, play, and behave better. It's like a masterclass in parenting.
   • Team B (First Aid for Parents): These parents go to a shorter, 3-day course. They learn the basics of handling daily struggles like sleep, eating, and hygiene. It's a quick, helpful guide.
3. The Finish Line: After the courses are done, the researchers check in again. They ask the same questions right after the course, and then again one year later, and finally two years later. They want to see if the stress levels go down and stay down.

What They Are Measuring
The main thing they are watching is Parent Stress. They use a special checklist called the "Parenting Stress Index" to see if the parents feel less overwhelmed. But they aren't just looking at stress. They are also checking:

• Confidence: Do the parents feel more capable?
• Quality of Life: Is the family happier?
• Child Skills: Is the child getting better at daily tasks like dressing themselves or talking?
• Money: How much does it cost the health system to run these programs?

The Rules of the Game
The scientists are being very careful. They are using a "Randomised Controlled Trial" (RCT), which is the gold standard of science. It's like a double-blind taste test, but for parenting. The people analyzing the data won't know which team the parents were on until the very end, so they can't accidentally favor one side.

They also have strict rules:

• No Concurrent Participation: Parents can't be in another parenting program at the same time.
• The Right Players: The kids must be between 2 and 6 years old and have a confirmed diagnosis of autism.
• The Language Rule: If a parent doesn't speak enough Norwegian to understand the course without a translator, they can't join. This is to make sure everyone gets the full message.

Why This Matters
Right now, we don't really know for sure which program is the "magic bullet." Some studies suggest the "Incredible Years" program is great, but they were small and didn't follow the families for long enough. Other studies say maybe a simpler course is just as good. This study is trying to settle the debate with a big, clear answer.

If the "Incredible Years" program turns out to be much better, it could mean that hospitals need to invest more time and money into these long, detailed courses. If the "First Aid" course works just as well, then maybe we can save money and get help to more families faster.

The Bottom Line
This paper is the map for a journey that is just beginning. The researchers have built a solid plan to test two different ways of helping parents. They aren't claiming to have the answer yet; they are just setting up the experiment to find it. By the time they finish in 2026, they hope to have a clear picture of how to best support the foremen building the unique structures of children with autism. Whether the answer is the masterclass or the quick guide, the goal is the same: to make sure every parent has the tools they need to build a happy, healthy life for their child.
