Description of intervention(s) / exposure
The Australian Centre for Heart Health (ACHH) developed the Back on Track online program to support patients who have had an acute cardiac event. The program was developed using the principles of self-management, patient centred care, cognitive behaviour therapy and motivational interviewing. The Back on Track program is designed to help patients manage their health behaviours and emotional wellbeing. The online Back on Track program begins with a mandatory goal-setting module, followed by four self-selected modules relating to a) dietary change; b) physical activity and reduced sitting; c) smoking cessation; and d) cardiac blues, anxiety and depression. Each module includes written information as well as motivational interviewing tasks such as comparing advantages and disadvantages of each behaviour change, and preparing action plans and coping plans for making changes. Each module takes up to one hour to complete.
This project will trial the Back on Track online program, and test two methods of program delivery – one self-directed by the patient (Group 1), and one supported with two telephone sessions with a health psychologist (Group 2). Both Group 1 and Group 2 patients will be asked to complete online modules that are relevant to them, in their own time and in any order. Group 2 patients will also be offered two telephone sessions (each up to 45 minutes duration) with a registered and experienced Health Psychologist to assist them in goal-setting and overall self-management while undertaking program modules. The health psychologist(s) will be trained by Associate Professor Rosemary Higgins who designed the Back on Track program and prepared the telephone scripts for the two support sessions. The first telephone session will occur when patients are completing the mandatory online goal-setting module. The health psychologist will use motivational interviewing strategies to support patients to articulate clear and achievable goals and to identify areas of behavioural and emotional self-management that they want to address. At completion of the first session, the second telephone session will be scheduled for a mutually agreed time. An SMS reminder will be sent 24-hours prior to each telephone session appointment to facilitate engagement.

Assessing adherence. Both Group 1 and 2 participants will be asked in the post-program questionnaire to indicate which Back on Track modules they completed. In addition, website analytics will be recorded, including number of modules started and completed, number of logins, time spent online for each module. Completion and time of each telephone session will be recorded for Group 2 participants.

Outcomes
Primary outcome [1] 322281 0
As the first primary outcome, we will examine differences between groups 1 and 2 in the proportion of patients who were classified as non-depressed at baseline, post-program and follow-up (according to a PHQ-9 score of <6). PHQ-2 and PHQ-4 scores will also be examined as these scores exclude more ‘somatic’ items such as feeling tired, having problems with sleep and appetite which may be confounded by other physical issues.

Timepoint [1] 322281 0
Pre-program, immediately post-program (2 months after registration), and at 6 months (4 months after program completion).
Primary outcome [2] 322385 0
As the second primary outcome, we will examine differences between groups 1 and 2 in the proportion of patients who were achieving physical activity guidelines of at least 150 minutes of physical activity per week at baseline, post-program and 6 month follow-up. Active Australia Survey will be used to assess physical activity. The 8-item AAS measures frequency of walking, moderate activity and vigorous activity in the last two weeks. Participants will be classified, according to the National Heart Foundation of Australia (NHFA), as achieving the recommended target for adequate physical activity for CHD secondary prevention if they have been engaged in at least 150 minutes of physical activity per week combined across the three domains assessed.

Secondary outcome [1] 377942 0
Secondary outcome measures will include change over time in smoking rates. Amongst smokers, the proportion of people who have quit smoking will be compared for the two groups. Smoking status will be assessed by self-report by asking participants “Are you a smoker?” Current smokers will be asked how many cigarettes they smoke per day. Former smokers will be asked when they quit smoking.

Sample size and power
Sample size calculation indicated that 147 subjects per group or a total of 294 will be required to detect, with 90% power and type I error of 5% (two-tailed), an absolute intervention effect of 17% based on the primary outcome variable, expected PHQ-9 depression response (defined as PHQ-9 score of less than 6 and a reduction in PHQ-9 score of at least 5 points, 4 months after randomisation) This intake number accounts for 10% attrition over the course of the study to the 4-month follow-up assessment (estimated sample sizes at 4-month follow-up: N=264; N per group=132). Sample size was calculated using Stata v16 and was based on a depression care management intervention for hospitalized cardiac patients which found an effect size of 17% using PHQ-9 scores. Estimated sample sizes for a two-sample proportions test:
Pearson's chi-squared test. Ho: p2 = p1 versus Ha: p2 != p1
Study parameters: alpha = 0.0500, power = 0.8000, delta = -0.1700 (difference), p1 = 0.5100, p2 = 0.3400

Data analysis
In evaluating outcomes, there will be two groups: group 1 – ‘self-directed’; group 2 – ‘supported’. All statistical analyses will be performed on an intention-to-treat (ITT) basis with alpha level set at 0.05. In the case that ITT produces a null finding, it is possible that this is due to participants in the supported group not participating in the additional telephone sessions (that is, not receiving the intended treatment). In order to test that hypothesis, we will then undertake treatment-received (TR) analysis (also called Per Protocol) whereby only those who received the treatment according to the protocol are included. This will enable us to determine whether any differences were obtained between the those who received the ‘self-directed’ treatment and those who received the ‘supported’ treatment. P values below 0.05 will be considered significant for the primary outcome, and P values below 0.01 will be considered significant for secondary outcomes.
Primary outcome measures
Depression, physical activity and healthy diet: As the main outcomes, we will examine differences between groups 1 and 2 in the proportion of patients who were:
1. classified as non-depressed at baseline, post-program and follow-up (according to a PHQ-9 score of less than 6). PHQ-2 and PHQ-4 scores will also be examined as these scores exclude more ‘somatic’ items such as feeling tired, having problems with sleep and appetite which may be confounded by other physical issues.
2. achieving physical activity guidelines of at least 150 minutes of physical activity per week at baseline, post-program and follow-up.
3. achieving healthy dietary guidelines of DQT scores greater than 60% at baseline, post-program and follow-up.


Secondary outcome measures
Smoking rates: Amongst smokers, the proportion of people who have quit smoking will be compared for the two groups.
Change over time in other psychosocial and attitudinal measures: Change over time in scores on the GAD-7, WHO-5, SF-12, self-efficacy and readiness to change behaviours and emotions will be compared between groups 1 and 2 using repeated measures analysis of variance (ANOVA). Multiple regression analysis, with group entered as a potential predictor, will be used to predict patients with greatest improvements in GAD-7, WHO-5, SF-12 and self-efficacy scores, and readiness to change behaviours and emotions.
Assessing program acceptability
Back on Track acceptability: Proportions will be calculated for all items on the program acceptability scale.

Summary
Brief summary
The Australian Centre for Heart Health (ACHH) developed the Back on Track online program to help patients manage their health behaviours and emotional wellbeing after a cardiac event. This project will trial the Back on Track program, and test two methods of program delivery – one self-directed by the patient, and one including two telephone sessions with a health psychologist. The project aims to assess whether patients obtain enhanced benefit through psychologist support, over and above benefit obtained through completing the online program alone. We anticipate that Back on Track will assist patients' recovery, and represents a flexible, easily accessible, user-friendly and effective alternative or adjunct to centre-based programs.
