TE: teacher; D: drumming; CN: control; TRF: Teacher's Report Form; Difference: difference score (post-intervention/control minus baseline); AN: anxiety problems; AH: attention deficit/hyperactivity problems; I: inattention (subscale of AH); OD: oppositional defiant problems. A positive value for difference scores indicates improvement whereas a negative value indicates worsening of symptoms.
