Anxiety Inventory (BAI)
Graph: Beck Anxiety Inventory Total Scores

Pre and post scores on the Beck Anxiety Inventory (shown in the graph above) suggest that those who completed the programme moved from the higher end of the moderate (M = 24.22, SD = 10.98) to the lower end of the moderate (M = 15.75, SD = 10.67) range on the measure. Changes were statistically significant, z = 5.98, p < .001, and reflect a large effect size (r = 0.49). At the pre measurement time point, 73.6% had anxiety scores in the severe and moderate ranges, this dropped to 37.5% by the end of Level 1. See the table below for how these scores redistributed into the other categories.
% in each category | Anxiety (BAI) | Depression (BDI) | ||
PRE | POST | PRE | POST | |
Minimal | 8.3 | 30.6 | 12.5 | 52.1 |
Mild | 18.1 | 31.9 | 25 | 22.5 |
Moderate | 44.4 | 25 | 37.5 | 15.5 |
Severe | 29.2 | 12.5 | 25 | 9.9 |
Totals | 100 | 100 | 100 | 100 |
These results are broken down into the four main diagnostic subgroups in the table below.
BAI | n | Pre Mean | Post Mean | T value | df | Sig. |
Agoraphobic | 2 | 46.00 | 28.5 | 7.00 | 1 | .090 |
Social Phobia | 16 | 22.75 | 16.75 | 3.24 | 15 | .005 |
Panic Disorder | 7 | 33.42 | 18.42 | 5.89 | 6 | .001 |
GAD | 13 | 23.31 | 13.07 | 5.09 | 12 | .000 |
OCD | 29 | 22.86 | 15.89 | 3.51 | 28 | .002 |
Beck Depression Inventory (BDI)
Graph: Beck Depression Inventory Scores

Mean scores on the Beck Depression Inventory were in the moderate range pre-intervention (M = 22.38, SD = 8.76) and showed a statistically significant drop to within the mild range post-intervention, (M = 15.22, SD =11.1), z = 5.12, p < .001, which represented a large effect size (r =.43). While 62.5% were classified has having moderate and severe depression before the programme, 25.4% were classified as such by the end.
A comparison of change across the four main diagnostic categories is available in the table below.
BDI | N | Pre Mean | Post Mean | T value | df | Sig. |
Social Phobia | 16 | 19.87 | 14.43 | 2.31 | 15 | .036 |
Panic Disorder | 7 | 22.86 | 14.28 | 2.98 | 6 | .024 |
GAD | 13 | 22.07 | 14.15 | 2.86 | 12 | .014 |
OCD | 28 | 23.25 | 16.85 | 3.04 | 27 | .005 |
Agoraphobic | 2 | 21.00 | 17.00 | .571 | 1 | .671 |
The Fear Questionnaire
Graph: Fear Questionnaire Total Phobia Scores
A Wilcoxon Signed Rank test revealed a statistically significant difference between pre and post level 1 Total Phobia scores, z = 5.85, p < .001. The mean phobia score decreased from 35.08 (SD= 21.22) to 23.02 (SD=19.68), and represented a large effect size (r = .49).
The Yale Brown Obsessive Compulsive Scale
Graph: Yale Brown Obsessive Compulsive Scale
For those with OCD (n = 29), global (Y-BOCS) scores dropped significantly from 23.45 (SD = 5.84) to 17.55 (SD = 7.75), t (28) = 6.30, p <.001, (Cohen’s d = 1.17), indicating an overall reduction in the severity of OCD symptoms with a large effect size.
Penn State Worry Questionnaire (PSWQ)
Graph: Penn State Worry Questionnaire
Participants’ scores on the Penn State Worry Questionnaire dropped from 61.00 (SD = 9.23) to 48.46 (SD = 10.37), t (12) = 5.13, p < .000, which reflects a large effect size (Cohen’s d= 1.42).
Social Phobia Inventory (SPIN)
Graph: SPIN Scale
A statistically significant reduction in SPIN scores were observed, t (16) = 5.84, p<.001, from pre intervention (M = 46.29, SD = 9.14) to post level 1 intervention (M = 32.94, SD = 12.77), reflecting a large effect size (Cohen’s d = 1.41).
The Work and Social Adjustment Scale
Graph: The Work and Social Adjustment Scale
A statistically significant reduction in mean scores on the Work and Social Adjustment Scale was observed, t (70) = 7.44, p < .001, from pre intervention (M = 26.67, SD = 98.76) to post level 1 intervention (M = 18.39, SD = 9.90), reflecting a large effect size (Cohen’s d = .88).
