Parent-led stepped care for traumatised children: parental factors that predict treatment completion and response

Background: Stepped care cognitive behavioural therapy for children after trauma (SC-CBT-CT; aged 7–12 years) can help to increase access to evidence-based trauma treatments for children. SC-CBT-CT consists of a parent-led therapist-assisted component (Step One) with an option to step up to standard therapist-led treatment (Step Two). Studies have shown that SC-CBT-CT is effective; however, less is known about what parent variables are associated with outcome of Step One. Objective: To examine parent factors and their relationship with completion and response among children receiving Step One. Method: Children (n = 82) aged 7–12 (M = 9.91) received Step One delivered by their parents (n = 82) under the guidance of SC-CBT-CT therapists. Logistic regression analyses were used to investigate whether the following factors were associated with non-completion or non-response: the parents’ sociodemographic variables, anxiety and depression, stressful life experiences and post-traumatic symptoms, negative emotional reactions to their children's trauma, parenting stress, lower perceived social support, and practical barriers to treatment at baseline. Results: Lower level of educational achievement among parents was related to non-completion. Higher levels of emotional reactions to their child's trauma and greater perceived social support were related to non-response. Conclusions: The children seemed to profit from the parent-led Step One despite their parents` mental health challenges, stress, and practical barriers. The association between greater perceived social support and non-response was unexpected and warrants further investigation. To further increase treatment completion and response rates among children, parents with lower education may need more assistance on how to perform the interventions, while parents who are very upset about their child's trauma may need more emotional support and assurance from the therapist.
