Students did not show as much change in their self-concept as The Centre School
students and the standard deviation (SD) shows that the spread is consistent across
both schools. The statistics for this inventory also confirm that without Joe the
average score for CVC is an increase, and therefore a slight improvement of 0.25, and
the number of students who made a positive change was 63%.
Figure 6.2e.i (in appendix 6.2e) shows the findings according to the Beck clinical
range for the students in both schools before and after music therapy. It is interesting
because before music therapy 38% of CVC students scored below average but this
figure increased to 75% after music therapy, whereas 67% of Centre School students
were below average. This shows that scores improved for the majority of students at
CVC and to a much greater extent than for students at The Centre School.
In summary, it is the degree to which the BSCI results changed which highlights the
differences between pupils in the two schools. The results suggest that The Centre
School students have much greater need and were less self-aware before music
therapy, achieving a more realistic sense of self after twenty weeks of therapy. For
many of them, this was the first time they had somebody to listen to them which is
backed up by their comments in their interviews (7.7.2). More students at CVC, on
the other hand, were more self-aware and within the healthy range according to the
Beck, at the start of music therapy and their scores showed less change.
