青少年性行为的理论和实证研究已经确定了个人属性和社会经验的贡献;然而，很少有模型阐明了青少年性行为的发展途径，包括（1）青春期之前和早期评估的因素和（2）青春期的二元经验，为性行为提供了机会（即，约会）。使用来自前瞻性研究的数据，结构方程模型被用来测试预测19岁青少年性行为的模型，该模型由终身性伴侣的数量表示。研究的预测因素是在30个月大时评估的社交能力和冲动性，在12 - 13岁时测量的身体特征和与同龄人的经历，第一次恋爱关系的年龄以及16岁时饮酒的频率。更多性参与的途径以一些期望的个人属性为标志（例如，社交性）和同伴经验（例如，高质量的友谊）。然而，这些关联是由早期开始的浪漫关系和更频繁地使用酒精在青春期中期介导的。更早开始的浪漫关系和更频繁的饮酒被预测为更大的社交能力和更少的冲动在童年，更高质量的友谊和更大的同龄人接受在青春期早期，和更成熟的外观和身体吸引力（女性）在13岁。研究结果暗示了一个复杂的途径，导致19岁时性伴侣的积累更多。这条途径始于童年，包括个人品质，同伴接受，浪漫关系和酒精使用。
Theories and empirical studies of adolescent sexual behavior have identified the contributions of personal attributes and social experiences; however, it is rare that models have clarified developmental pathways to adolescent sexual behavior that include ( 1) factors assessed prior to and early in adolescence and (2) dyadic experiences in adolescence that provide the opportunity for sexual behavior (i.e., dating). Using data from a prospective study, structural equation modeling was used to test a model predicting adolescent sexual behavior at age 19, denoted by the number of lifetime sexual partners. Predictors examined were sociability and impulsivity assessed at 30 months of age, physical characteristics and experiences with peers measured at age 12 - 13, the age of first romantic relationship, and frequency of alcohol use at age 16. The pathway to greater sexual involvement was marked by some desired personal attributes (e.g., sociability) and peer experiences (e.g., higher quality friendships). These associations were mediated, however, by earlier initiation of romantic relationships and more frequent use of alcohol in middle adolescence. Earlier initiation of romantic relationships and more frequent alcohol use were predicted by greater sociability and less impulsivity in childhood, higher quality friendships and greater peer acceptance in early adolescence, and a more mature appearance and physical attractiveness ( among females) at age 13. The findings imply a complex pathway that leads to a greater accumulation of sexual partners by age 19. This pathway begins in childhood and includes individual qualities, peer acceptance, romantic relationships, and alcohol use.
