Questionnaire responses from 13- to 17-year-old girls in four all-female and three coed institutions were used to determine rates and causes of institutional homosexuality. Rates were as high in coed as in single-sexed institutions. The overall rates of homosexuality for all seven institutions were 14% for "going with or being married" to another girl, 10% for passionately kissing, 10% for writing love letters, and 7% for having sex, beyond hugging and kissing, with another girl. The data suggest that previous homosexuality, often experienced in other correctional programs, explains much of the variance in institutional homosexuality.
来自四所全女子院校和三所男女同校院校的13至17岁女孩的问卷调查回复被用于确定机构内同性恋的发生率和原因。男女同校院校的发生率与单性别院校一样高。所有七所院校的同性恋总体发生率为：与另一个女孩“交往或结婚”的占14%，热烈亲吻的占10%，写情书的占10%，除拥抱和亲吻外与另一个女孩发生性行为的占7%。数据表明，之前在其他矫正项目中经常出现的同性恋经历，在很大程度上解释了机构内同性恋的差异。
