Recovery Assessment Scale
A Wilcoxon Signed Rank test identified a significant increase in mean total scores for the RAS at the post intervention time point z= 2.02, p <.05, reflecting a moderate effect size (Cohen’s r: 29). Looking at the RAS sub-scale scores, significantly higher scores were identified post intervention for users on the ‘Ability to rely on others’ subscale only, z=2.31, p<.05, with a large effect size Cohen’s r: .46). The difference between pre and post intervention means on the ‘Confidence and Hope’, ‘Willingness to ask for help’, ‘Goal and Success Orientation’, and ‘No domination by symptoms’ subscales were not statistically significant. See the table below for test statistics and figures for differences in pre and post intervention means and graphs on the following page for visual representations.

Drug Attitude Inventory
A Wilcoxin Signed Rank test identified a statistically significant increase in mean scores on the DAI-10 from pre intervention (M=6.87 SD=2.72) to post intervention (M=7.79; SD=2.43) z=2.4, p<.05, with a large effect size (Cohen’s r: .35). This indicates that service users who completed the measures reported more positive views towards medication after completing the programme.
