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. 2A significant group and time interaction effect denotes that the response over time differed between groups (P < 0.05). 3Expenditure data was collected in Australian dollars (AUD) on a 7-Point scale which was analyse by its midpoints. 4Mean 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. 5Mean 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. 6Rosenberg’s global self-esteem score (Low self-esteem = 0–14, Normal self-esteem = 15-25 and High self-esteem = 16-30). 7Perceived general health (Poor = 1, fair = 2, good = 3, very good = 4, excellent = 5).
