↵a Analysis of covariance was used to adjust differences after 4 and 12 months for differences in the corresponding scores at baseline.
↵b All scale scores run from 0 (worst) to 100 (best); thus positive differences represent better results in the intervention group
↵c Standardised effect sizes relative to baseline standard deviation of relevant scale or subscale.
↵d Significant at P<0.01.
↵e Significant at P<0.05.
