The present study explored the targeting of a preventative information provision intervention delivered to children following accidental injury by assessing the impact of initial traumatic distress on response to treatment. Analyses were based on baseline and 6-month outcome of child traumatic stress in a control (n = 28) and an intervention group (n = 31). Moderation of treatment outcome by initial levels of child traumatic stress was assessed through multiple hierarchical regression analyses. Results indicated the interaction between treatment provision and initial level of posttraumatic stress significantly predicted 6-month outcome (β = -.42, p = .019). When initial distress was high, children in the control group demonstrated an increase in trauma symptoms, and had significantly higher trauma symptoms at follow-up than those in the treatment group (d = 0.94, p = .008). When initial distress was not elevated, no significant differences were noted between the groups. These results indicate that a preventative early intervention may be best targeted at children presenting with the specific risk factor of high initial distress.
