True Love Waits? A Sibling-Comparison Study of Age at First Sexual Intercourse and Romantic Relationships in Young Adulthood
真愛要等待?青
少年初次性行為年齡與浪漫關係的比較研究

摘要

         這項研究測試青春期初次性交時機是否可以預測在成年期的浪漫結局,包括結合,伴侶數量和關係不滿意的程度。研究參與者乃是全國青少年健康長期研究所選取之1,659位同性別之手足,從其青春期(平均年齡為16歲)追蹤至成年早期(平均年齡為29歲)。參與者之初次性交的時機被歸類為早期(14或更早的年齡),中期(在15至19歲),與晚期(19歲以上年齡)。相較於第一次性交發生於早期和中期者,那些較晚發生第一次性愛者,其成年後之婚姻出狀況情形、非婚同居、及浪漫伴侶數目皆較少。而在那些已婚或有一位同居伴侶者中,發生首次性行為之時間較晚者,其關係不滿意程度顯著降低,即使控制了遺傳和家庭環境差異之影響(使用兄弟-比較模式)、成人期之人口統計結果、以及在青春期約會的程度,結果仍是一樣。這些研究結果顯示,長期人生的研究方法對於瞭解浪漫關係有重要貢獻。

Abstract

        This study tested whether the timing of first sexual intercourse in adolescence predicts romantic outcomes in adulthood, including union formation, number of romantic partners, and relationship dissatisfaction. Participants were 1,659 same-sex sibling pairs from the National Longitudinal Study of Adolescent Health, who were followed from adolescence (mean age = 16 years) to young adulthood (mean age = 29 years). The timing of participants’ first sexual intercourse was classified as early (at age 14 or earlier), on time (between the ages of 15 and 19), or late (at age 19 or older). Compared with early and on-time age at first sex, late age at first sex was associated with decreased odds of marriage or nonmarital cohabitation and fewer romantic partners in adulthood. Among individuals who had married or cohabited with a partner, late timing of first sex was associated with significantly reduced levels of relationship dissatisfaction, even after controlling for genetic and environmental differences between families (using a sibling-comparison model), demographic outcomes in adulthood, and involvement in dating during adolescence. These results underscore the contribution of a life-span approach to our understanding of romantic relationships.
