Brief Name: The ‘Breaking the Man Code’ Workshops delivered by Tomorrow Man to male secondary school students in Australia.

One workshop delivered to year 10, 11 or 12 male secondary school students in Australia by a trained facilitator from Tomorrow Man (tomorrowman.com.au). The workshop is usually provided within school class time to male students of one year level at secondary school and comprises interactive group activities. The workshop delivery is face-to-face or online and takes approximately 2 hours. Each workshop includes between 30 to 35 male students, with an average of three workshops to three different groups of students, totalling an average of 100 students per school. Multiple workshops at the one school are usually delivered by the one facilitator. The workshop explores the impact of the ‘man code’ – the unwritten rules about how to be a man – on the wellbeing of Australian men. It explores who wrote the rules and investigates why men feel obliged to live up to gender expectations and stereotypes. The workshop then allows boys to open up about their experience living with the ‘man code’ in order to understand that they can write their own rules. The workshop aims to lessen the negative impact of some masculine norms and to develop protective factors such as positive attitudes towards help-seeking, emotional expressiveness, and social support. Students will complete a baseline questionnaire approximately 2 weeks prior to the workshop and a follow-up questionnaire 2-6 weeks after the workshop. Adherence to the intervention will not be monitored.

Outcomes
Primary outcome [1] 324990 0
Difference between the two study arms for mean change in intentions to seek help, as measured by an adapted version of the General Help Seeking Questionnaire (GHSQ) (Wilson et al. 2005. Measuring help seeking intentions: Properties of the General Help Seeking Questionnaire. Canadian Journal of Counselling, Vol. 39(1), 15-28.). The GHSQ has been found to have reliability and validity, and to be a suitable measure of help-seeking intentions in a range of contexts. Item or total scores can be used in analysis, and the scale can be modified to add in extra response items. The GHSQ asks participants: “If you were having a personal or emotional problem, how likely is it that you would seek help from the following people or services?” Response options include: an intimate partner; friend; parent; other relative; mental health professional; doctor; or minister or religious leader. The following additional response options will be included: phone helpline; people online; and someone at school. The final scale comprises 10 items and participants responded on a seven-point Likert scale (range 10-70). Higher scores reflect higher intentions to seek help.
Timepoint [1] 324990 0
Following randomisation of schools, the baseline assessment for the intervention group will occur within the two weeks prior to receiving the workshop. The follow-up assessment will then occur two to six weeks after the workshop. For the control group, following randomisation, the baseline assessment and follow-up assessment will be four to eight weeks apart, with usual school curriculum in-between.
Secondary outcome [1] 386469 0
Difference between the two study arms in mean change of conformity to masculine norms as measured by the Conformity to Masculine Norms Inventory (Mahalik et al. (2003). Development of the Conformity to Masculine Norms Inventory. Psychology of Men & Masculinity, 4: 3-25). The Conformity to Masculine Norms Inventory (CMNI-22) is a 22-item scale will assess participants’ conformity to 11 potentially harmful masculine norms: emotional control; risk-taking; violence; dominance; playboy; self-reliance; primary of work; power over women; heterosexual presentation; physical toughness; and pursuit of status (Mahalik et al., 2003). Items are answered on a 4-point likert scale (0 = strongly disagree to 3 = strongly agree), range 0 – 66. Higher scores indicate higher conformity to masculine norms. The CMNI-22 has been found to have good internal consistency, differential validity, and test-retest reliability (Mahalik et al. 2003). The playboy subscale questions and one of the power over women subscale questions were modified for suitability in a school population. ‘I would feel good if I had many sexual partners’ to ‘I would feel good if I had many girlfriends/boyfriends’ ‘If I could I would frequently change sexual partners’ to ‘If I could I would frequently change girlfriends/boyfriends’ 'I love it when men are in charge of women' to 'I think it is okay for men to be in charge of women'

Secondary outcome [2] 386470 0
Difference between the two study arms in mean change in depression risk as measured by the Male Depression Risk Scale (Herreen D, Rice SM, Zajac I. Development and Validation of the MDRS Short Form for Clinical Use. In preparation.) This 7-item scale was chosen to capture the externalising symptoms of depression common to males - emotional suppression, drug use, alcohol use, anger and aggression, somatic symptoms, and risk taking (in the last two weeks). Items are answered on an 5-point Likert scale (0 = none of the time to 4 = all of the time), range 0 – 28. High scores indicate higher depression risk.

Secondary outcome [3] 386471 0
Difference between the two study arms in mean change in subjective social support as measured by the emotional/informational subscale of the Medical Outcomes Study Social Support Survey (MOS-SS). Moser A, Stuck AE, Silliman RA, Ganz PA, Clough-Gorr KM. The eight-item modified Medical Outcomes Study Social Support Survey: psychometric evaluation showed excellent performance. J Clin Epidemiol. 2012;65(10):1107-16. This 8-item subscale asks participants about the kind of support available to them. The items are answered using a 5-point Likert scale (1 = none of the time to 5 = all of the time), range 8 - 40. Higher scores reflect high levels of perceived support. The scale has been found to have good psychometric properties among young non-clinical populations. (Giangrasso & Casale, 2014).

Difference between the two study arms in mean change in quality of life as measured by the the Child Health Utility Instrument (CHU9D). Stevens K. Assessing the performance of a new generic measure of health-related quality of life for children and refining it for use in health state valuation. Applied health economics and health policy. 2011;9(3):157-69. This 9-item scale asks participants about their functioning today across domains of worry, sadness, pain, tiredness, annoyance, school, sleep, daily routine, activities. The items are answered using a 5-level response category (1 = I don’t feel X today to 5 = I feel very X today). The CHU9D has been recommended for measuring quality of life in adolescent populations in Australia (Chen et al, 2015).

Secondary outcome [5] 401675 0
The CHU9D will also be used to derive health state utility values by using the previous published value set, reflecting Australian adolescents’ preferences, which will be combined with the period of the trial to derive QALYs (Ratcliffe J, Huynh E, Chen G, Stevens K, Swait J, Brazier J, et al. Valuing the Child Health Utility 9D: Using profile case best worst scaling methods to develop a new adolescent specific scoring algorithm. Soc Sci Med. 2016;157:48-59.) Health service use will be assessed using a modified Resource Utilization Questionnaire (RUQ) (Smaldone A, Tsimicalis A, Stone PW. Measuring resource utilization in patient-oriented comparative effectiveness research: a psychometric study of the Resource Utilization Questionnaire. Res Theory Nurs Pract. 2011;25(2):80-106.) The 21-item questionnaire was developed to measure the health services and costs of health care. This questionnaire has been modified from the version used in the Young Minds Matter Survey to enable self-report by adolescents and will ask which health professionals participants have seen in the past two weeks for their mental health (number of the visits, location and costs of visits), and medications taken for emotional or behavioural concerns in the past two weeks (type, dosage) ( Hafekost J, Lawrence D, Boterhoven de Haan K, Johnson SE, Saw S, Buckingham WJ, et al. Methodology of Young Minds Matter: The second Australian Child and Adolescent Survey of Mental Health and Wellbeing. Aust N Z J Psychiatry. 2016;50(9):866-75.). Resource use and unit costs will be combined to derive a total cost for each participant. The standard Australian unit costs of relevant resource use units collected through the RUQ will be extracted from different sources include the Independent Hospital Pricing Authority, the Medicare/Pharmaceutical Benefit Scheme fees and State-based services.

Following randomisation of schools, the baseline assessment for the intervention group will occur within the two weeks prior to receiving the workshop. The follow-up assessment will then occur two to six weeks after the workshop. For the control group, following randomisation, the baseline assessment and follow-up assessment will be four to eight weeks apart, with usual school curriculum in-between.

Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Allocation will involve contacting the holder of the allocation schedule who will be “off-site” or at central administration site.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomisation using a randomisation table created by computer software (i.e. computerised sequence generation).

The trial will use a stratified design where schools will be stratified by location (state and rurality) and delivery mode (face-to-face or online) and then within the strata schools will be randomly allocated to either the intervention group or the wait list control group.

Efficacy
Statistical methods / analysis
For 90% power and a two-sided 5% significance level, we will require a sample of 1000 participants across 40 schools (a minimum of 25 students on average per school) to detect a standardised effect size of 0.3 in mean GHSQ score between the study arms. Sample size accounts for the correlation of outcomes within schools in 0.03 (Lane et al., 2018), and assumes that 20% of students do not respond at follow-up and includes two additional schools (one school in each arm) to allow for potential loss to follow-up of schools post-randomisation.

Descriptive statistics will be used to summarise school and participant characteristics between study arms. Analysis will use an intention to treat approach. We will use linear mixed effect models to estimate the difference in mean GHSQ scores at follow-up between the study groups, with random effects for school and fixed effects for study group, baseline GHSQ scores, and stratification factors. Estimated intervention effect will be reported as difference in mean GHSQ scores between intervention and control groups, with 95% confidence interval and p-value. We will undertake a similar analysis for secondary outcomes. Strategies will be undertaken to minimise missing data, and sensitivity analyses will be conducted to assess the robustness of the missing data assumption. A full statistical analysis plan will be developed adhering the SPIRIT statement. We will analyse responses to open-ended questions using inductive thematic analysis.
