Evaluating a Web-Based Mental Health Service for Secondary School Students in Australia: Protocol for a Cluster Randomized Controlled Trial

Background: Mental health problems are prevalent among Australian secondary school youth; however, help-seeking is low. Schools offer an ideal setting to address these concerns. The Black Dog Institute has developed a Web-based mental health service for secondary schools that is modeled on the principles of stepped care. The Smooth Sailing service aims to improve help-seeking and reduce anxiety and depressive symptoms in secondary school students. The acceptability of this service has been demonstrated in a pilot study. A full trial is now warranted.

Objective: This study protocol for a cluster randomized controlled trial (RCT) aims to evaluate the effectiveness of the Smooth Sailing Web-based service for improving help-seeking intentions and behavior, and reducing depressive and anxiety symptoms, alongside other mental health outcomes, when compared with a school-as-usual control condition in secondary school youth.

Methods: This RCT aims to recruit 1600 students from 16 secondary schools in regional and urban locations throughout New South Wales, Australia. Schools are randomly assigned to the intervention or school-as-usual control condition at the school level. Approximately 100 students from 1 or multiple grades are recruited from each participating school. Participants complete measures at 3 timepoints: baseline, 6 weeks post, and 12 weeks post, with the primary outcome assessed at 12 weeks posttest. Participants assigned to the intervention condition register to the Web-based service at baseline and receive care in accordance with the service model. Participants in the control condition receive school-as-usual.

Results: The first baseline assessment occurred on February 22, 2018, with the 12-week endpoint assessments completed on Friday, June 29, 2018. Control schools are currently receiving the service, due for completion by June 30, 2019. The trial results are expected to demonstrate improved help-seeking intentions and behavior among students assigned to the intervention condition, alongside improvements in symptoms of depression, anxiety, distress, and other mental health outcomes when compared with students assigned to the control condition.

Conclusions: To our knowledge, this is the first time that a Web-based mental health service based on the principles of stepped care will have been integrated into, and evaluated in, the Australian school context. The findings of this trial will have implications for the suitability of this type of service model in Australian schools and for the delivery of school-based mental health services more broadly.
