Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Participants in the intervention group will receive behavioural counselling to increase their physical activity. This will occur over 12 weeks: weekly for the first 6 weeks, then fortnightly for the later 6 weeks, for a total of 10 sessions (inclusive of the first and last week).

Sessions will consist of discussing personal goals, barriers, enablers, pros and cons of physical activity and cognitive and behavioural strategies to aid in the process. Topics of discussion will be guided by the Transtheoretical Model of Behaviour Change. They will also receive an informational handbook designed specifically for this study, a physical activity diary and a Fitbit device.

The initial and final sessions will be conducted in person at the university campus and is expected to take between 1.5 to 2 hours, including assessments. The rest of the sessions will take place via a range of modes, depending on the preference the participant (e.g. telephone, online video chat) and are expected to last between 15 to 30 minutes. The topics covered in these sessions will be tailored according to each participants' context (e.g. stage of change, support needs and barriers).

Measures of study feasibility and safety will be taken, including recruitment rates, session completion, reasons for non-compliance/withdrawal and adverse events.

The intervention will be delivered by a doctoral student, under the guidance of an experienced supervisory team.

Behaviour
Comparator / control treatment
This study will use an attention control group. The control group will receive a general physical activity recommendation and the same informational handbook as the intervention group but modified to not include behaviour change theories or strategies. They will also receive the same physical activity diary and Fitbit device.

To attain the same level of contact, participants in the control group will be contacted at the same frequency (weekly for the first 6 weeks, then fortnightly for the later 6 weeks) to repeatedly administer a symptom questionnaire.
