4.5 Data analysis: The quantitative investigation
Data include:
72 HADS questionnaires (each of the six participants completed 12 questionnaires),
72 QLQ-C30 questionnaires (each participant completed 12 questionnaires)
18 SOC questionnaires (each participant completed 3 questionnaires),
72 sets of four music therapy questions (each participant completed 12 sets of
questions)
Data were scored and analysed according to the questionnaire manuals.
Statistical analysis
This study used a repeated measures design with three time points (baseline/pre-test,
post-test, and follow-up) to explore the effect of 10 BMGIM sessions on mood and
quality of life of the six participants.
Descriptive statistics were performed on the three standardized self-reports
questionnaires, and the four specific music therapy questions. Scores were compared
to established norms (HADS, QLQ-C30, SOC).
Inferential non-parametric statistics were used to test for differences between scores at
the three data time points mentioned. The Willcoxon Matched Pairs test was used to
test possible significant differences in this sample between pre-test and post-test
scores, and between pre-test and follow-up scores of selected variables.
Effect sizes of selected variables were determined by Cohen’s d calculation.
As the study did not include a control group, and the sample was small (n=6)
statistical results cannot be generalized to other cancer patients. However, they may
give an indication of how significant the treatment was for these specific participants
