This study examines family and child characteristics, parent and peer relationships, and early adolescent behavior as statistical predictors of trajectories of number of sexual partners from mid-adolescence through early adulthood using data from 527 participants in the Child Development Project. Early adolescent developmental antecedents accounted for modest variance in number of sexual partners. Latent growth models revealed that African American race, more advanced pubertal development, lower parental monitoring knowledge, association with more deviant peers, and lower GPA in early adolescence each predicted having more sexual partners at age 16. In addition, non-African American race, lower child IQ, higher parental monitoring knowledge, and lower early adolescent internalizing problems each was associated with a higher rate of growth in number of sexual partners over time at the ages following 16. Latent growth mixture modeling identified subgroups with distinct trajectories of involvement with sexual partners that were associated with family and child characteristics, parent and peer relationships, and behavior in early adolescence.
本研究利用儿童发展项目中527名参与者的数据，考察家庭和儿童特征、父母与同伴关系以及青少年早期行为，将其作为从青少年中期到成年早期性伴侣数量轨迹的统计预测因素。青少年早期的发育前因在性伴侣数量方面解释了适度的方差。潜在增长模型显示，非裔美国人种族、青春期发育更提前、父母监督知识较低、与更偏离常规的同伴交往以及青少年早期较低的平均绩点，每一项都预测在16岁时会有更多性伴侣。此外，非非裔美国人种族、儿童智商较低、父母监督知识较高以及青少年早期内化问题较少，每一项都与16岁之后各年龄段性伴侣数量随时间增长的较高速率相关。潜在增长混合模型确定了具有不同性伴侣参与轨迹的亚组，这些轨迹与家庭和儿童特征、父母与同伴关系以及青少年早期行为相关。
