Parenting Intervention Combined with Acceptance and Commitment Therapy: Processes of Change

Abstract:

Objectives

We report an investigation into processes of change in a randomized controlled trial of Stepping Stones Triple P (SSTP) and acceptance and commitment therapy (ACT) for families of children with cerebral palsy (CP). In comparison with the control group, the SSTP-only group showed improvements in child behavior problems and emotional symptoms and the SSTP-plus-ACT group showed benefits in child behavior problems, child hyperactivity, dysfunctional parenting styles, child functional performance in the mobility domain, child quality of life, and parental adjustment.

Methods

Sixty-seven parents of children with CP were randomly allocated to one of three groups: waitlist control, SSTP-only and SSTP-plus-ACT groups. We investigated three potential processes of change: parenting style, parental attitude to child emotion, and parental psychological flexibility. We used bootstrapping to perform the mediation analysis.

Results

Contrary to the existing literature, we find that neither dysfunctional parenting styles nor parental attitude to child emotion were significant mediators of the intervention effect on child behavior and adjustment. Consistent with existing literature, we find that psychological flexibility mediates the intervention effect on dysfunctional parenting styles (overreactivity confidence interval [CI] = −0.4750 to −0.115) and parental adjustment (depressive symptoms CI = −6.5641 to −0.5922; stress CI = −6.0546 to −0.4195).

Conclusions

Overall, our findings support the conclusion that ACT makes a unique contribution to parenting intervention.
