subject's behaviour was recorded in this way at
baseline, for one week, and throughout a nine week
treatment period.
The treatment period was divided equally into a
treatment phase, reversal phase (a return to baseline
conditions), and a further treatment phase. (Figure 5)
The graph charts the total number of episodes of
inappropriate behaviour which occurred each week. It
shows a high incidence of inappropriate behaviour at
baseline - a rate of 2.43 incidents per day. With the
introduction of music therapy there was an immediate
drop to a daily rate of 0.71, followed by a further drop to
0.29 when the behaviours were all but extinguished.
The third week of treatment saw a slight increase to a
daily rate of 0.43 incidents. During the reversal phase
the rate of inappropriate behaviours after remaining
stable for one week returned to a level close to the rate
monitored at baseline. However, the reintroduction of
227
treatment brought about an immediate drop to an
average level of 0.24 daily incidents for the final three
weeks - the lowest recorded level during the entire
treatment period.
The results suggest that the subject responded very
favourably to treatment. Involvement in music sessions
brought about an immediate reduction in inappropriate
behaviours after both the baseline and reversal
conditions.
It would also appear that the treatment effect was
lasting.
It was not until the second week of the reversal phase
that the inappropriate behaviours returned to the
baseline level. Significant changes were also brought
about by the removal and reintroduction of the music
treatment. There was an increase in inappropriate
