Implementation of the Swedish Guideline for Prevention of Mental ill-health at the Workplace: study protocol of a cluster randomized controlled trial, using multifaceted implementation strategies in schools.

Background: Given today's high prevalence of common mental disorders and related sick leave among teachers, an urgent need exists for a more systematic approach to the management of social and organizational risk factors within schools. In 2015, we launched the first Swedish occupational health guideline to support a structured prevention of these risks at the workplace. The existence of guidelines does however not guarantee their usage, as studies show that guidelines are often underused. Knowledge is therefore needed on effective implementation strategies that can facilitate the translation of guidelines into practice. The primary aim of the randomized waiting list-controlled trial described in this study protocol is to compare the effectiveness of a multifaceted implementation strategy versus a single implementation strategy for implementing the Guideline for the prevention of mental ill-health at the workplace within schools. The effectiveness will be compared regarding the extent to which the recommendations are implemented (implementation effectiveness) and with regard to social and organisational risk factors for mental ill-health, absenteeism and presenteeism (intervention effectiveness).

Methods: The trial is conducted among primary schools of two municipalities in Sweden. The single implementation strategy is an educational strategy (an educational meeting). The multifaceted strategy consists of the educational meeting, an implementation team and a series of workshops. The outcome measure of implementation effectiveness is guideline adherence. The primary outcome of intervention effectiveness is exhaustion. Secondary outcomes include demands at work, work organization and job contents, interpersonal relations and leadership, presenteeism, work performance, recovery, work-life balance, work-engagement, self-reported stress, self-perceived health, sickness absence and psychosocial safety climate. Process outcomes as well as barriers and facilitators influencing the implementation process are assessed. Data will be collected at baseline, 6, 12, 18 and 24 months by mixed methods (i.e. survey, focus-group interviews, observation).

Discussion: The study described in this protocol will provide valuable knowledge on the effectiveness of implementation strategies for implementing a guideline for the prevention of common mental disorders within schools. We hypothesize that successful implementation will result in reductions in school personnel's perceived social and organizational risk factors, mental ill-health and sick-leave.
