The purpose of this study was to identify the structural relationships between the
supervisory style, supervisees’ developmental level, the supervisory working alliance,
supervisees’ positive cognitive coping, and supervisees’ satisfaction with supervision in
music therapy supervision. The participants consisted of a total of 218 music therapy
students and professionals who had received supervision within the previous six months.
The participants completed five measures, and the data were analyzed using the
structural equation modeling method. Firstly, in the student supervisees, the supervisory
style was a significant variable that directly affected the supervisees’ satisfaction and
had an influence through the mediating effect of the supervisory working alliance.
Supervisees' developmental level had an influence on the supervisees’ satisfaction as
mediated by the supervisory working alliance and the positive cognitive coping. So,
supervisees’ developmental level had an indirect effect as mediated by two variable.
Supervisory working alliance was a variable to enhance supervisees’ satisfaction. Second,
in the professional supervisees, supervisory style had an influence on the satisfaction as
mediated by the supervisory working alliance. Supervisees’ developmental level had no
influence on the supervisees’ satisfaction. In other words, the professional supervisees had
no influence on the supervisory style and supervisees’ developmental level and only
affected by the supervisory working alliance. Third, the result of the statistical
significance between the two group, there was a significant difference in the route of
supervisory working alliance and satisfaction. This result showed that the professional
supervisees had more excellent capacity of supervisory working alliance than students
group. Based on the results above, it was concluded that the supervisory style was more
significant variable to increase supervisees’ satisfaction than supervisees’ developmental
level. Supervisory working alliance was an essential variable to increase the supervisees'
satisfaction, but student supervisees must be required positive cognitive coping in order
to supervisory working alliance.
