Follow-up and Replication of Prevalence of Bulimia Among College Students, 1991-1992

These data were collected as a follow-up and replication of Colby, Ware, and Zuckerman's "Prevalence of Bulimia Among College Students" (Log #00871) study which surveyed a random sample of college students from Harvard University in 1982. The purpose of the replication was to examine changes in the prevalence of dieting behavior and eating disorder symptoms from 1982 to 1992. The follow-up was designed to assess whether any change in eating behaviors had occurred during the transition to early adulthood. In 1991-92, surveys were sent randomly to 1200 students; 799 (564 women and 235 men) completed questionnaires were returned. A follow-up of 732 of the 901 subjects in the original sample was also conducted. Participants from both the replication and follow-up studies completed surveys that were similar to the 1982 questionnaire. Surveys included questions about demographic and health background, eating habits, dieting, exercise, and specific symptoms of eating disorders, including 26 items from the Eating Disorder Inventory. The follow-up questionnaire also included questions about family and career, as well as the Rosenberg Self-Esteem Scale. The Murray Research Archive holds original record paper questionnaires, and numeric file data for both the replication and follow-up samples. The Murray Archive also holds data from the original study (See Colby, Zuckerman, and Ware, 00871).

本数据集为对Colby、Ware与Zuckerman于1982年开展的《大学生中贪食症的患病率》（编号Log #00871）研究的复刻与追踪研究。该原始研究于1982年针对哈佛大学的随机抽样大学生群体开展问卷调查。其中，本次复刻研究旨在考察1982年至1992年间节食行为与进食障碍症状患病率的变化情况；追踪研究则用于评估在向成年早期过渡的过程中，进食行为是否发生了改变。1991至1992年间，研究人员向1200名学生随机发放问卷，最终回收有效问卷799份（其中女性564份、男性235份）。此外，研究团队还对原始研究的901名受试者中的732人开展了追踪调查。参与复刻与追踪研究的受试者均填写了与1982年原版问卷内容相近的调查问卷，问卷涵盖人口统计学特征与健康背景、饮食习惯、节食行为、运动情况以及进食障碍特异性症状，其中包含进食障碍量表（Eating Disorder Inventory）的26个条目。本次追踪研究的问卷还增设了家庭与职业发展相关问题，以及罗森伯格自尊量表（Rosenberg Self-Esteem Scale）。默里研究档案馆（Murray Research Archive）保存了本次复刻与追踪研究的原始纸质问卷记录与数值文件数据，同时也留存了原始研究的相关数据（详见Colby、Zuckerman与Ware，编号00871）。
