Abstract
Implementation of effective school-level mental health promotion initiatives is challenging. This paper presents findings from the beyondblue schools research initiative, a cluster randomised trial which aimed to promote student mental health. It sought to implement emotional skills through curriculum, greater community linkages and whole-school environment change in 25 schools in three states of Australia. Using qualitative process evaluation data collected during the three years of the project, we describe key features of the intervention that, according to the project facilitators, influenced its implementation. Project design flexibility to meet individual school needs and provision of sufficient resources appeared to be crucial for successful implementation.
