Evaluation of the National Roll-out of the Triple P Online System across four new online variants; Family Transitions Triple P Online, Stepping Stones Triple P Online, Resilience Triple P Online, and Teen Triple P Online.

This study will take advantage of a roll-out of the Triple P Online System (TPOS) within Australia to collect data on effectiveness in a practice-as-usual context. The TPOS has been funded for dissemination to all eligible Australian parents by the Commonwealth Government’s Parenting and Education Support Program since 2022 and is a web-based platform that provides parents with access to Triple P Online variants including the four newly rolled out or soon to be rolled out programs under evaluation in the current study (commencing July 2025); Family Transitions Triple P Online, Stepping Stones Triple P Online, Resilience Triple P Online and Teen Triple P Online. The Triple P Online programs that form part of TPOS provide parents with a range of resources and tools, including interactive modules, videos, and self-help materials, to support their parenting journey. The programs contain between four and ten online modules that each take approximately 30 minutes to complete. Participants will have access to the TPOS for 12 months from enrolment, however, for the purposes of this study, observation will only occur for 6 months after enrolment.
