Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Individual Cognitive Behaviour Therapy administered by post-graduate students completing their Master of Clinical Psychology supervised by a Clinical Psychologist 1x1.5-2hrs per week for 10 weeks targeting issues common in depression and overweight/obesity (e.g. self-efficacy, withdrawal, body image, eating behaviours) with concurrent semi-structured physical exercise program of 45 minutes 3x per week for 10 weeks administered by trained 4th Year Exercise Science students. Adherence to treatment is monitored via audio/visual recordings for fidelity check to ensure treatment program is followed. Participant adherence will be monitored by therapist/trainer (record of attendance).

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Allocation concealment will be conducted using investigators blind to enrollment/allocation procedures. i.e. Participants will be de-identified upon enrollment (screened by an investigator blind to the study interventions). A new investigator will randomly assign the de-identified participant to an intervention group via computer.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Participants will be randomly assigned to one of two groups using a computerised random number generator.
Masking / blinding
Open (masking not used)

Statistical methods / analysis
Power analysis was conducted assuming alpha level of 0.05 and a moderate effect size (demonstrated in similar previous research .5-.7 low end indicates ~36pp extra to allow for 10-15% drop-out) Power = .95.

A 2 (group) x 3 (time) Repeated Measures ANOVA will be conducted. Physiological and anthropometric data will be collected pre and post intervention and will be analysed using a 2 (group) by 2 (time) one-way ANOVA.
