Randomization and blinding
ADHD
The principal Investigator selected the subjects by reviewing the selection and exclusion criteria among ADHD children and youth participants. Random assignments were made using random number table generated by the Excel program to generate a random list with 2 groups and 60 samples.The registered subjects were equally assigned to the ADHD Control group or ADHD music therapy group assigned by the random number table in the order of registration. This study is a music therapy intervention study. Therefore, the principal investigator of the ADHD children and youth participants, music therapists, and research will not be blinded by the assigned treatment. However, data statisticians will be blinded to group allocation. In order to protect the study subjects as much as possible, alphabet letters replaced their names.
