A Cluster Randomized Controlled Trial to Evaluate HeadCoach: An Online Mental Health Training Program for Workplace Managers

OBJECTIVE: Mental ill-health is now the leading cause of sickness absence and occupational incapacity in high-income countries. This study evaluated HeadCoach online manager training, designed to improve confidence and managerial behaviours that create mentally healthy workplaces. METHODS: A cluster randomized controlled trial was conducted comparing managers who received HeadCoach (N = 87) to waitlist control (N = 123). Managers' confidence and behaviour were investigated at baseline, post-intervention and follow-up. Psychological distress of direct reports was evaluated. RESULTS: Confidence significantly increased post-intervention only, however per-protocol analyses indicated a significant improvement for program completers compared to control at both time points. Responsive and preventive behaviours significantly improved. Psychological distress of direct reports remained unchanged. CONCLUSIONS: HeadCoach online mental health training is an effective and scalable way to improve managers' confidence and workplace practices around mental health. The impact on direct reports remains unknown.
