Pilot randomized controlled trial of a novel web-based intervention to prevent posttraumatic stress in children following medical events

Kassam-Adams, Nancy and Marsac, Meghan L. and Kohser, Kristen L. and Kenardy, Justin and March, Sonja and Winston, Flaura K. (2016) Pilot randomized controlled trial of a novel web-based intervention to prevent posttraumatic stress in children following medical events. Journal of Pediatric Psychology, 41 (1). pp. 138-148. ISSN 0146-8693


Objective: To assess feasibility and estimate effect size of a self-directed online intervention designed to prevent persistent posttraumatic stress after acute trauma.

Methods: Children aged 8–12 years with a recent acute medical event were randomized to the intervention (N = 36) or a 12-week wait list (N = 36). Posttraumatic stress, health-related quality of life, appraisals, and coping were assessed at baseline, 6, 12, and 18 weeks.

Results: Most children used the intervention; half completed it. Medium between-group effect sizes were observed for change in posttraumatic stress severity from baseline to 6 weeks (d = −.68) or 12 weeks (d = −.55). Exploratory analyses suggest greatest impact for at-risk children, and a small effect for intervention initiated after 12 weeks. Analysis of covariance did not indicate statistically significant group differences in 12-week outcomes.

Conclusions: This pilot randomized controlled trial provides preliminary evidence that a self-directed online preventive intervention is feasible to deliver, and could have an effect in preventing persistent posttraumatic stress.
