ABSTRACT

Sexual maturation is one method by which researchers account for developmental timing during growth. In a longitudinal motor performance study (MPS), mothers reported their own recalled age at menarche and their daughters.’ Approximately twenty years later, a sample of those daughters provided their recalled age at menarche. Study purposes were to determine whether: 1) average age at menarche for this sample was similar to the extant literature; 2) daughters’ and mothers’ ages at menarche collected during the MPS differed; and 3) a retrospective assessment of age at menarche (daughters’ reports as adults) was correlated to recall data (mothers’ reports of daughters’ age). Descriptive and inferential statistics were calculated for the sample; via probit analysis, MPS females were average in maturational timing. Mothers and daughters did not differ in menarcheal age; daughters’ initial reported mean age at menarche correlated with their recalled mean age at follow up, r = 0.82 (p < .0001).

摘要

性成熟是研究人员解释生长过程中发育时间的一种方法。在一项纵向运动表现研究（MPS）中，母亲报告了她们初潮初潮的年龄和女儿的年龄。大约二十年后，这些女儿的样本提供了初潮时的回忆年龄。研究目的是确定：1​​）该样本的初潮平均年龄与现有文献相似；2）MPS期间初潮初婚的女儿和母亲的年龄有所不同；3）对初潮年龄的回顾性评估（成年女儿的报告）与召回数据（母亲关于女儿年龄的报告）相关联。计算样本的描述性和推论统计；通过概率分析，MPS雌性的成熟时间平均。母女的初潮年龄没有差异。女儿最初报告的初潮平均年龄与其回忆的平均年龄相关，r = 0.82（p <.0001）。
