Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The intervention is a 12 week, e-health enabled, structured health promotion intervention targeted at improving health related quality of life and reducing chronic disease risk factors in women between 18 and 50 years of age who have previously been treated for cancer. All women in the intervention arm will receive health education material, including a Program Journal (in the form of an interactive iBook), and access to the program website. The iBook includes sections on healthy eating, sleep, exercise advice, tips for managing fatigue and stress, mindfulness, and will encourage women to bring together these various components of the health education provided and incorporate them into their lives over a 12-week period. The iBook includes a weekly exercise planner, where women are encouraged to use this journal daily and to plan ahead for their exercise in the following week. Participants will receive access to self-directed resources (via the website) and three 30-60 minute individual, personalised consultations (via video conference) at weeks 1, 6 and 12 will be provided by a registered nurse trained in the intervention. The nurse consultations will include individual goal setting as well as discussion and health education about physical activity, healthy eating, stress, sleep, menopause and sexuality after cancer and strategies to promote intervention adherence.

Study design
Purpose of the study
Educational / counselling / training
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
The Research Assistant determining if a subject is eligible for inclusion in the trial, and completing study assessments, will be blinded to which group the subject is allocated to. Computer randomisation will be completed by the Study Manager upon completion of study enrolment and baseline assessments.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Permuted block randomisation using computer generated number sequences
Masking / blinding

Efficacy
Statistical methods / analysis
Quantitative analysis:
Between-group differences at 12 and 24 weeks will be estimated using a linear mixed model with a treatment-time interaction. Sensitivity analyses will be used to explore the impact of non-ignorable missing data.

Qualitative analysis:
Qualitative data collected (qualitative interview and semi-structured feasibility questionnaire) at week 24 will be content analysed to assess the study objectives.
