Pre Level A and Post Level A
Beck Depression Inventory (BDI)
The average score for people moved from the moderate range (Md = 27) to the mild-moderate range (Md = 12) on the measure (see graph below). A Wilcoxin Signed Rank test revealed that the reduction was statistically significant, z= -10.77, p = .000, with a medium effect size (Cohen’s r = 0.49).

Patient Health Questionnaire-9 (PHQ-9)
Comparison of patient scores on the PHQ-9, pre and post Level A indicated that, on average, those who completed rated themselves in the moderately severe range (Md = 18) prior to the intervention and in mild to moderate range (Md = 7) following intervention. This reduction in mean scores is statistically significant, A Wilcoxin Signed Rank test revealed z= – 10.90, p = .000, with a large effect size (Cohen’s r = 0.50).

Pre Level B and Post Level B
Prior to 2016, data was analysed from pre Level A to post Level B. However feedback from the clinical team in 2016 highlighted that the time between completing level A to commencing level B can vary significantly. There can be lengthy gaps in commencing level B due to the service user’s choice and personnel circumstances, such as fitting around work, family commitments or study. As a result it was decided to analysed the data from pre level B to post level B instead.
Beck Depression Inventory (BDI)
Pre and post scores on the Beck Depression Inventory (see graph below) demonstrate that the average score for people who completed Level B of the Depression Programme moved from the upper end of the mild range range pre Level A (M = 18.8, SD = 11.71) to the lower end of the mild range (M = 13.6, SD = 11.3). This reduction in the mean score is statistically significant, t(15) = 5.45, p < .05, with a small effect size (Cohen’s d = 0.45).

Patient Health Questionnaire-9 (PHQ-9)
Comparison of patient scores on the PHQ-9, indicated that, on average, those who completed Level B rated themselves in the mild range (Md =7) prior to Level B and remained in the mild range (Md = 6) following Level B. A Wilcoxin Signed Rank Test showed this reduction in mean scores is statistically significant, z = – 2.34, p <.05), with a medium effect size (Cohen’s r = 0.33).
