Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Participants in the intervention group will received a brochure aimed at promoting mental health help-seeking based on the Theory of Planned Behaviour (TPB). The intervention was developed specifically for this study by the primary researcher, who is a registered psychologist, with support from the research team. During the development phase, a consultative group of key stakeholders were interviewed to inform the design, layout and content of the intervention, including primary health care providers, mental health professionals, health care executives, representatives from community organisations, and consumers.

The intervention includes behaviour change messages targeting the three main components of the TPB: attitudes, subjective norms, and perceived behavioural control.
Messages designed to promote favourable attitudes towards help-seeking aim to communicate that help-seeking is a good and useful thing to do. Examples include ‘speaking about your concerns is the best thing to do’, ‘mental health problems can be prevented and treated’, and ‘it will be useful for you and for others if you speak about your concerns’. Messages to promote favourable subjective norms aim to increase perceived social support and reduce mental health-related stigma. Examples include ‘we all have fears and concerns from time to time’, ‘when you experience such concerns you are not alone’, and ‘your doctor expects you to talk about your concerns.’ Messages to promote perceived behavioural control aim to strengthen self-efficacy and reinforce personal choice in help-seeking. Examples include ‘speaking with a doctor about your concerns helps you to take control of your health,’ and ‘it is important to find a doctor who you can trust, and who will work with you to choose the services and treatments that suit your needs’.

The intervention also addresses barriers to help-seeking and includes mental health literacy messages as suggested by previous research and stakeholders. Key barriers to help-seeking identified and addressed include normalisation of the problem, perceived need, and burdening others. Examples of messages targeting perceived barriers include ‘sometimes people don’t want to speak with their doctor, because they think that its normal to get less enjoyment from life as they get older. There is little evidence to suggest this is the case,’ ‘it doesn’t matter how mild or severe your symptoms are’, and ‘you are not burdening others by talking about your mental health’. Mental health literacy information includes details on how and where to seek help, and what treatment options are available. For example, ‘talk to your doctor when you are experiencing symptoms such as headaches and pain, or feel unhappy or down,’ ‘options may include changes to your diet, exercise, day to day activities, medication, or referral to a mental health professional, and ‘the following organisations provide information and support…’.

The brochure will be presented to participants as part of an online survey. Graphic images of each page of the brochure will be presented to participants in the intervention group, and participants will be asked to download a pdf copy of the brochure to read and retain. Participants will be able to read the brochure at their own pace.

Whilst we are not monitoring adherence, time spent reviewing the brochure will be used as a proxy measure.

Behaviour
Comparator / control treatment
A comparison group will be included in this study. Participants in the comparison group will receive a brochure developed specifically for this study by the primary researcher with support from the research team. The content of the comparison brochure was informed by interviews with key stakeholders.

The comparison brochure includes the same mental health literacy messages as the intervention brochure and additional general health information based on public health messages. The general health messages include definitions of good health, and physical, social and mental wellbeing, prevalence data on chronic diseases in Australia, national health guidelines on sleep, diet and exercise, and information on where to find reliable sources of health information (e.g., pharmacies, doctors’ surgery, community health centres and government websites). The appearance of the brochure is comparable to that of the intervention brochure to control for design effects.

The brochure will be presented to participants as part of an online survey. Graphic images of each page of the brochure will be presented to participants in the comparison group, and participants will be asked to download a pdf copy of the brochure to read and retain. Participants will be able to read the brochure at their own pace.

Help-seeking intention

Change in participants intention to seek help for mental health concerns will be measured using one item from a Theory of Planned Behaviour (TPB) questionnaire designed by the research team. The item asks participants to rate their intention to speak with a doctor about their mental health on a 7-point Likert scale from strongly disagree to strongly agree.

The TPB questionnaire is a self-report measure designed to assess TPB constructs of attitudes, subjective norms, perceived behavioural control and intentions within the context of mental health help-seeking. The questionnaire was pilot tested by the research team with 54 older adults (aged 65 and older) in Perth, Western Australia. Reliability testing demonstrated acceptable internal consistency of the measure (Cronbach’s alpha .69 to .87).

Help-seeking behaviour

Help-seeking behaviour will be measured by asking participants if they had spoken to a doctor about their mental health, and if they had received treatment from a mental health professional. Participants will be asked to respond to each item with yes/no, and if yes, to specify how long ago they spoke to a doctor or received professional treatment, and the number of times. These self-report items were designed by the research team specifically for this study.

Statistical methods / analysis
This is a feasibility study therefore no power analyses were conducted. Based on sample size estimates for pilot randomised controlled trials 100 participants are required; 50 participants for each arm. As online surveys have a high drop-out rate we will aim to recruit 200 people.

Intention to treat analysis will be used. As this is primarily a feasibility study, descriptive statistics will be used to report on primary and secondary outcomes.

For the primary feasibility outcome, and secondary outcomes utility, retention, and help-seeking behaviour, descriptive statistics will be calculated as counts and percentages. For all other secondary outcomes, descriptive statistics will be calculated as mean, mode, and standard deviation. Estimated effect sizes and 95% confidence intervals for each outcome will be calculated.

Other inferential analyses will be completed to determine preliminary differences in changes between pre-post measurement scores for the intervention and comparison groups. Unadjusted analyses will be performed. Binary outcomes are help-seeking behaviour. Continuous outcomes are help-seeking intention, attitudes, subjective norms, and perceived behavioural control. Change in the binary outcome will be analysed using chi-squared test, and change in continuous outcomes will be analysed using unpaired t-tests.

Qualitative data will be analysed using thematic analysis in Microsoft excel.

Summary
Brief summary
This study is a pilot, feasibility randomised controlled trial to test the feasibility of a theory-based behaviour change intervention designed to promote help-seeking for mental health problems among older adults in Australia. The intervention aims to improve the three main components of the Theory of Planned Behaviour, which have been shown in previous research to influence mental health help-seeking: attitudes, subjective norms, and percevied behavioural control. The intervention was designed in consultation with key stakeholders. Adults aged 65 years and over living in metropolitan areas in Australia will be recruited online using Qualtrics research services. In keeping with a preventative, population health approach, inclusion is not dependant on mental health symptomatology. Participants will be randomly allocated to an intervention or comparison group using Qualtrics computer software. Participants in the intervention group will receive an information brochure based on the theory of planned behaviour. Participants in the comparison group will receive a brochure with general health information. The primary outcome is intervention feasibility. Secondary outcomes include intervention utility, retention, time spent reviewing the brochure, changes in help-seeking intention, attitudes, subjective norms and perceived behavioural control, and help-seeking behaviour. Data will be collected at baseline, immediately post-intervention and three weeks post-intervention. Descriptive statistics will be calculated to analyse the data. Intention to treat analysis will be used. Increasing the likelihood of older adults engaging professional mental health supports early may reduce the individual, social and economic burden of mental ill-health and promote healthy ageing.
