1
Independent group t-tests comparing participants in the PS and Usual Care groups at baseline.
2
Z-tests of whether the regression co-efficient for effects are significantly different from 0, which included demographic variables, site of care and BASIS-R total score as covariates.
3
This change is significantly different from 0, indicating that there was a change in means over time within this treatment condition. This test does not compare the change between groups, only the change in the group identified.
4
PS group n=66
*
Analyses of the BASIS-R total and subscale did not include the BASIS-R total score as a covariate.
