The results of the students’ T scores according to the Beck clinical range (figure
6.2de.ii in appendix 6.2e) show that 71% of all students (8 students from The Centre
School and 7 from CVC) are within the average range for anxiety. The large
proportion of students shown to be in the Beck healthy range supports the view that
anxiety is difficult to measure by self-report because it is evident from the referrals
that the students do suffer from anxiety. The problems both in reporting and
measuring anxiety are discussed in chapter nine.
6.2.3 The Beck Disruptive Behaviour Inventory for Youth: descriptive statistics
The results for the BDBI were calculated in the same way as for the BAI which
means that a decrease in change score signifies improvement. Figure 6.2.3.1 shows
the difference in scores which The Centre School students gave.
