Purpose of the study
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)

Methods used to generate the sequence in which subjects will be randomised (sequence generation)
computerised sequence generation

Type of endpoint(s)
Statistical methods / analysis
Clinical and Statistical significance will be analyzed using a repeated ANOVA to compare change from pre to post treatment of 2 groups (treatment or no treatment). Analyses will be conducted on completers vs intent to treat analyses for all relevant variables. Groups will also be compared using t-tests and chi square analyses for demographic variables and baseline symptom measures.
Effect size to achieve sufficient power will be achieved at 52 participants. Sample Size calculations are based on power analyses conducted using GPower with alpha set at 0.05 and power=0.8 needing 52 participants for a large effect size between groups (n=26 per group)
