  1. 1Outcomes within each group and over time were determined by a mixed linear model for repeated measures using all available data at each time point using STATA (version 12.0).
  2. 2Baseline values were not significantly different between groups (independent t tests). 3A significant group and time interaction effect denotes that the response over time differed between groups (P = 0.05). 4Expenditure data was collected in Australian dollars (AUD) on a 7-point scale which was analyse by its midpoints. 5Mean predicted score indicating level of agreement with statement from a Likert Scale (1 = strongly disagree, 2 = somewhat disagree, 3 = somewhat agree, 4 = strongly agree), aScore assignment was reversed. 6Mean frequency for a typical week was collected on a 6 or 7-point scale which was analyse by its midpoint, with the maximum category being five or more times per week. 7Rosenberg’s global self-esteem score (Low self-esteem = 0-14, Normal self-esteem = 15-25, High self-esteem = 16-30). 8Perceived general health (poor = 1, fair = 2, good = 3, very good = 4, excellent = 5).
