epresent a student’s coping strategy which involves either an intention to hide, or an
inability to show, signs of weakness or emotional distress. Students who have had no
music therapy have not gained any further insight into their emotional well-being and
might respond more defensively. Students in group A, on the other hand, had had the
opportunity to express themselves in a therapeutic environment, develop greater selfawareness
and understand their emotions and even reasons for their behaviour.
6.3.5 The Beck Inventories for Youth: inferential statistics
Inferential statistics were used to support the findings made by descriptive statistics,
as with the primary data. The results from the MANOVA model (appendix 6.3c)
show that the mean change for group A was not significantly different to group B for
each of the Beck inventories’ parameters (BSCI p-value = 0.925; BAI p-value =
0.409; BDBI p-value = 0.179) 46 .
Table 6.3d in appendix 6.3 shows the change scores between the two groups. The
means for each scale are very similar and, as expected from a non-significant model
parameter, the 95% confidences are broadly the same. This suggests that the null
hypothesis, that there is no difference between group A and B, could not be rejected.
This means that the data did not show any significant influential factors. However,
the observed power for these tests are very low (BSCI p-value=5%; BAI p-
value=12%; BDBI p-value=26%), and this non-significant result is probably due to
the small number of students involved and/or the imbalance in CVC and The Centre
School students in the two groups.
6.4 Findings from the Beck Inventories for Youth: follow-up data
In order to show any change after a period of no music therapy, the short-term
follow-up data were compared: group A’s scores from data collection three to two,
and group B’s scores from data collection four to three. The results for each inventory

non-significant which supports the model requirement of equal variances.
