Raw data: 38 questions broken into 5 categories (active engagement, perceptual abilities, musical training, singing ability, emotional engagement). Each question uses a 5-point likert scale. 14 questions are reverse-coded.
Calculation:
Scores are calculated by finding the sum of the scores for each sub-scale, taking into account reverse-scoring for some questions. A "general factor" score is also calculated using certain questions from all 5 subscales. NOTE: this "general factor" subscore takes into account 17 or the 38 questions, and is not synonymous with the "totalscore" variable.
