6.2.2 The Beck Anxiety Inventory for Youth: descriptive statistics
The difference in the students’ scores using the Beck Anxiety Inventory (BAI) were
also compared before and after music therapy but these change scores were collated
in descending order, so that the decrease in anxiety related to improvement in the
student’s emotional well-being. Figure 6.2.2.1 shows an even spread across the
increase and decrease in scores of change in levels of anxiety after music therapy for
students at The Centre School.

The pattern is much flatter than was seen in the previous inventory for self-concept
(6.2.1.1) and the change scores hardly vary. John, who showed the greatest decrease
in anxiety, is an outlier because the impact of music therapy was particularly
significant for him (8.4).
The graph suggests that the students have tended to take the middle option (where 1 =
sometimes or 2 = often) offered in the questionnaires because there is no evidence of
students giving distinctive positive or negative results. This is known as tending to
the norm. It may be that the students answered in this way because they did not want
to be seen as anxious (9.3.3.1). Figure 6.2.2.2 shows the change scores for CVC after
music therapy.
