Children's satisfaction with a comprehensive study program—Results from the LIFE Child cohort study

Abstract

AbstractBackgroundResearch participants' satisfaction is a topic of great interest, especially in the context of longitudinal studies. Evaluation also represents an important component of quality management in the health care system. Adult studies found that personal characteristics, e.g., age, sex, ethnicity, and SES, can influence satisfaction with health care or study participation. Studies on paediatric participants are sparse.ObjectivesTo examine how children rated the study day of a cohort study and how these ratings were associated with sociodemographic and socioeconomic characteristics and retention in the context of a large cohort study.MethodsAnalyses were performed on 4‐ to 17‐year‐old participants of the German longitudinal cohort study LIFE Child (n = 2033). To assess the associations between overall satisfaction (high versus low/middle) and age, sex, body‐mass index, socioecomonic status, and participation in a follow‐up visit, we applied logistic mixed‐effects models.ResultsParticipants' overall satisfaction with the LIFE Child study day was high (“very good”: 67.8%). Overall satisfaction was higher in 7–9 years olds (odds ratio [OR] 2.00, 95% confidence interval [CI 1.51, 2.66) and 10–12 years olds (OR 1.51, 95% CI 1.16, 1.98) than in 4–6 years olds and 13–17 years olds. Children with obesity were less likely to participate in a follow‐up visit (OR 0.56, 95% CI 0.39, 0.78). Children reporting high overall satisfaction at the first study visit completed a follow‐up visit more frequently (OR 1.32, 95% CI 1.05,1.67).ConclusionsA high level of satisfaction increased participants' attendance at a follow‐up visit. Our results might be helpful for adapting the study program to the participants' needs in order to maximise retention and minimise attrition rates.
