Association of positive childhood experiences with flourishing among children with ADHD: A population-based study in the United States

Background: Child flourishing includes healthy social and emotional development and an open, engaged approach to learning. However, there remains a significant knowledge gap concerning a minority of children with ADHD who may demonstrate flourishing in one or more areas of functioning. This study investigated the association between positive childhood experiences (PCEs) and flourishing among children with ADHD. Method: Data were derived from the 2021 National Survey of Children's Health in the United States. The analysis included a final sample of 3727 children with ADHD. Logistic regression, restricted cubic splines, and random forest were used to examine the associations between seven PCEs and flourishing. Results: The adjusted odds of flourishing were 72% lower (odds ratio [OR] = 0.28,95% confidence interval [CI] = 0.21, 0.38) among children with PCE scores of 0-2 compared to those with scores of 3-5. In addition, the adjusted odds of flourishing were 2.45 times (95%CI = 2.00, 2.99) greater for children with PCE scores of 6-7 compared to those with scores of 3-5. These associations were consistent regardless of the level of adverse childhood experiences. Having a "connected caregiver" was the PCE most closely related to flourishing (unweighted OR = 3.24, 95%CI = 2.72, 3.89). Conclusions: Our findings revealed a positive association between higher levels of PCEs and greater flourishing among children with ADHD, regardless of the level of childhood adversity they experienced. These results highlight the importance of positive experiences in the lives of children with ADHD, with a specific focus on nurturing supportive relationships within families.
