Intervention/exposure
Study type
Interventional
Description of the intervention or exposure
The current randomised controlled trial investigates the effectiveness of a short online 15-minute refresher training module at maintaining managers’ confidence, attitude and behavioural changes delivered 6-months following the full manager mental health training program called MindWise Leadership (broader study registered in ANZCTR registration number ACTRN12625001102460). This refresher module has been adapted from the longer program specifically for this study.
MindWise Leadership is a 4-hour, evidence-based mental health training program for people-leaders and managers in the ambulance service, which aims to upskill people-leaders regarding employee mental health. The program was adapted from mental health training programs for workplace managers previously evaluated in randomised controlled trials (Gayed et al., 2019; Gayed et al., 2024; Milligan-Saville et al., 2017).
This training covers 3- modules:
• Module 1: Common Mental Illnesses: Common Mental Illnesses addressed the prevalence of mental illnesses in ambulance staff, how to recognise symptoms of mental illness, the impact of stigma in the workplace, how workplaces can encourage positive mental health, and managerial responsibilities regarding mental health.
• Module 2: Helping Your Employees: Helping your employees taught skills on recognising those at risk, providing support to employees experiencing mental illness, having a conversation about mental illness, facilitating help-seeking, supporting rehabilitation, and facilitating an employee’s return to work after mental health-related absence.
• Module 3: Creating a Mentally Healthy Workplace: Creating a Mentally Healthy Workplace focused on preventing mental ill-health by creating a mentally safe workplace, addressing psychosocial hazards, and promoting wellbeing and a positive culture through respectful managing.

Delivery of the refresher module to be evaluated in the current randomised controlled trial will be embedded into this trial for intervention participants 6-months after attending the full 4-hour in-person training. This refresher module is an online, interactive, self-paced module taking approximately 15-minutes to complete. It will briefly cover the key learning objectives of each of the three modules, using text, video content and quiz questions.
Participating in the parent-controlled trial evaluating the full 4-hour workshop (ANZCTR registration number ACTRN12625001102460) consists of completing a baseline survey, a post-intervention survey, a 6-month follow-up survey and a 12-month follow-up survey. The refresher module in this embedded RCT will be delivered to half of parent-controlled trial intervention participants selected randomly immediately after the 6-month follow-up survey, and accessed via a link at the completion of the survey. This online component will allow us to measure completion of the training module. The other half of the parent-controlled trial intervention participants will not receive the link to the refresher module after completing the 6-month training. Data collected at the 12-month follow-up will be compared to determine any differences between parent-controlled trial intervention participants allocated to the refresher module (embedded RCT intervention group) and those who were not allocated to receive the refresher module (embedded RCT control group).

Description of the comparator or control
Participants completing the 4-hour MindWise Leadership training workshop will be randomised into the embedded RCT intervention group (receiving the 15-minute refresher module) and the embedded RCT control group (no refresher module). The refresher module will be completed 6-months after the MindWise Leadership workshop.
Outcomes at the 12-month post-training data collection period will be compared between the embedded RCT intervention and control groups.

Statistical methods / analysis
NSW Ambulance will roll out the MindWise Leadership training (ANZCTR registration number ACTRN12625001102460) to all 600 of their leaders across NSW. Those opting to partake in the research evaluation who receive the training in the first 12 months will act as the intervention group. Those opting to partake in the research who will receive the training in the final 9 months will provide control data. 50% of participants in the intervention group of the larger controlled trial will be randomly allocated into the intervention group for the current embedded RCT and will receive the top-up refresher module immediately after the 6-month data collection timepoint. The other 50% will not receive the top-up refresher module but will have completed the MindWise Leadership training - they will act as the control group in this embedded RCT. This will allow us to evaluate the effectiveness of the top-up training module.

Following data collection, data will be cleaned and analysed in SPSS. Mixed model repeated measures (MMRM) will be utilised to determine group-by-time interactions and between group differences. This will allow us to measure changes in behaviour, confidence, stigma and knowledge at the 12-month post-intervention timepoint in those receiving the top-up refresher module (the intervention group) compared to those receiving the MindWise Leadership training without the top-up refresher modules (the control group).
