In this study, we examined demographic patterns of participation and persistence in high school elective music ensembles. We extend prior research that has only compared music and non-music students by explicitly modeling persistence across multiple years of ensemble enrollment. The research draws on data from the High School Longitudinal Study of 2009 and employs a zero-inflated Poisson regression model to analyze the data. This hurdle model, suitable for count data with a large number of zero observations, allows us to jointly examine factors related to enrolling in at least 1 year of a music ensemble (moving from 0 years to 1 year of music) and those factors related to accruing additional years of music ensemble enrollment (moving beyond 1 year to multiple years). We found that family socioeconomic status, birth-assigned sex, academic achievement, shared parent/student outside arts event attendance, and out-of-school arts engagement were significant predictors of both students’ music participation and persistence. By examining persistence, we add important nuance to the prior research examining demographic predictors of elective high school music enrollment, particularly for issues of birth-assigned sex and socioeconomic status in the choral context.

高中选修乐团的参与和坚持

在这项研究中，我们研究了高中选修音乐团的参与和坚持的人口统计模式。我们扩展了之前仅比较音乐学生和非音乐学生的研究，通过明确地建模多年合奏入学的持久性。该研究借鉴了2009年高中纵向研究的数据，并采用零膨胀泊松回归模型来分析数据。该障碍模型适用于具有大量零观测值的计数数据，使我们能够共同检查与参加至少 1 年音乐合奏（从 0 年音乐转向 1 年音乐）相关的因素以及与累积音乐团注册的额外年数（从一年到多年）。我们发现，家庭社会经济地位、出生性别、学业成绩、家长/学生共同参加校外艺术活动以及校外艺术参与是学生音乐参与和坚持的重要预测因素。通过检查持久性，我们为之前研究选修高中音乐入学的人口预测因素的研究添加了重要的细微差别，特别是对于合唱背景下的出生性别和社会经济地位问题。
