Parents' and children's experiences of participating in a randomized controlled clinical trial: AIDIT-QS.

Participation in a paediatric, complex randomized controlled trial (RCT) might add to the family burden when a child is diagnosed with a severe disease. Although important, there are only a limited number of papers describing this aspect of research from the family point of view. This study explored parents' and children's experiences of participation in a research study shortly after the child had been diagnosed with type 1 diabetes. Sixteen parents (nine mothers, seven fathers) and nine children were interviewed by an independent researcher about their inducement, the decision-making process within the family which led to their participation, and their experience of having done so. The result showed that the parents wanted to contribute to improve treatment for children with diabetes in general but also specifically for their own child. Older children were more involved in the decision making than the younger children. Study information needs to be communicated clearly and effectively since decision-making based on information of a clinical trial directly after the child's diabetes onset proved difficult. Being randomized to the intervention group in this specific study was considered somewhat burdensome. However, parental participants in both intervention and control group claimed that they would recommend participation in research studies to other parents in a similar situation, and so did the children. There was no difference between the mothers' and fathers' experiences. Parents’ expectations: A predominant driving force for the parents was the expectation that the study outcome could lead to something good for both their own child and other children with type 1 diabetes.Children’s perspective on participation: Older children appreciated being involved in the decision-making process and valued their role in potentially helping others with diabetes. However, younger children were less involved and often relied on their parents for decision-making.Personal benefits: Both children and parents considered it important to gain something for themselves; by participating, they could benefit from more advanced technology and more rigorous follow-ups.Importance of control group: It was important for the families’ motivation for completing the study that the researchers conveyed that the control group was as important for the outcome of the study as the intervention group.Future treatments: The parents felt that participation in the clinical trial could eventually lead to new treatments that could help their own child.Perceived safety: The fact that the clinical trial was considered well-planned and safe and implied no risk for the child made it easier to agree to participation.Effective communication: Since the onset of diabetes is emotionally stressful, and diabetes treatment itself is demanding, effective communication about the content of such a clinical trial is necessary, otherwise families may not understand what they are agreeing to.Burden on the intervention group: This clinical trial was somewhat burdensome for the intervention group to participate in; nevertheless, all of the families remained committed to their reasons for participating and completed the study.
