Summary

Level 1: Outcomes for the service users who completed Level 1 of the Anxiety Programme between January and December 2016 suggested significant reductions in anxiety and depression symptoms, OCD symptoms, and reductions in pathological worrying and social anxiety. The majority of effect sizes observed were within the large range as shown on the table below.

Note: ‘Cohen’s d’ or ‘r’ is reported depending on parametric or non-parametric test

Level 2: Outcomes for the service users who completed pre and post measures at Level 2 of the anxiety programme in 2016 suggested further decreases in anxiety and depression symptoms. However these reductions were not statistically significant. This could be explained by BDI and BAI scores already falling within the mild ranges of these scales.There was no significant difference identified in phobia ratings post Level 2, however, this was expected given that the majority of phobia work was covered in Level 1.

There were no statistically significant changes observed on the Social Safeness and Pleasure Scale, or Work and Social Adjustment Scale. This non-significance could be attributed to the lower sample size in the Level 2 part of the programme.

Changes in scores for most measures have been consistently positive across the data since 2011, following both Level 1 and Level 2. It should be noted that the differences in results between years may be attributable to changes in sample size.
