Examined differences in the number and types of problems as well as in self-reported self-concept between 232 middle and low SES pre- and postmenarcheal adolescents. The study also examined differences in these variables across four developmental levels of menarcheal status: Initial, Intermediate, Middle, and Established. These data were analyzed by a multiple ANOVA technique, and significant differences were found between pre- and postmenarcheal girls and between the two social class groups. Postmenarcheal adolescents had more problems, but were also higher on self-concept variables. Low SES females experienced the menarche earlier than middle class SES females, had different problems, and described themselves differently on the self-concept measures. These data were interpreted as supporting the view that menarche onset is a positive event for most young females.
研究了232名月经初潮前和月经初潮后的中低社会经济地位青少年在问题数量和类型以及自我报告的自我概念方面的差异。该研究还考察了这些变量在月经初潮状态的四个发育水平（初始、中间、中期和稳定期）之间的差异。这些数据采用多因素方差分析技术进行分析，结果发现月经初潮前和初潮后的女孩之间以及两个社会阶层群体之间存在显著差异。月经初潮后的青少年有更多问题，但在自我概念变量方面得分也更高。低社会经济地位的女性比中产阶级女性更早经历月经初潮，存在不同的问题，并且在自我概念测量方面对自己的描述也不同。这些数据被解释为支持月经初潮对大多数年轻女性来说是一个积极事件的观点。
