There is a need for developmentally tailored intervention approaches that empower parents to respond to adolescent school refusal in the context of internalising disorders. Partners in Parenting Plus-Education (PiP-Ed+) is a manualised coach-assisted online parenting programme that has been co-designed with parents, youth and education-sector experts to fill this gap. It addresses multiple parenting factors associated with adolescent school refusal and internalising disorders.

This study aimed to evaluate the acceptability, feasibility and preliminary indications of efficacy of PiP-Ed+.

An open-label, uncontrolled trial was conducted using a mixed-methods design. Participants were 14 Australian parents of adolescents (12–18 years) who had refused school in the context of internalising disorders.

PiP-Ed+ was viewed as highly acceptable and feasible. Coaching sessions in particular were perceived as valuable and appropriate to the parents’ level of need, although longer-term support was suggested to sustain progress. Between baseline and post-intervention, there were significant increases in parents’ self-efficacy to respond to adolescent school refusal and internalising problems, and concordance with evidence-based parenting strategies to reduce adolescent anxiety and depression. Days of school refused and carer burden did not change.

Findings support the value of proceeding to evaluate the efficacy of PiP-Ed+ in a randomised-controlled trial. Results are interpreted in the context of study limitations.
