The Journal of Child Psychology and Psychiatry, vol. 62, no 7, p. 842–852.
«This study had two aims: first, to identify distinct trajectories of romantic partnering from age 18 to 35 years in a large population-based sample; second, to examine the association between teacher-rated behavior at age 10–12 years and trajectories of partnering, with adjustment for the child’s sex and socioeconomic background.» (p. 843)
«Data were obtained from the Quebec Longitudinal Study of Kindergarten Children (QLSKC), a population-based sample (n = 3,020) born in 1980/1981 (Rouquette et al., 2014). The sample comprised 2,000 children (1,001 boys) who were randomly selected and 1,017 children (593 boys) who scored at or above the 80th percentile for disruptive behaviors at the end of kindergarten (age 6 years) with gender-specific cutoffs. […] Ratings of children’s behavior were obtained from school teachers using the Social Behavior Questionnaire when the children were aged 10–12 years (Tremblay, Desmarais-Gervais, Gagnon, & Charlebois, 1987).» (p. 843)

«After adjustment for sex and family background, inattention and aggression–opposition were uniquely and additively associated with increased likelihood of following an early-partnered-separated trajectory from age 18 to 35 years, while inattention and anxiety were associated with an increased likelihood of following a delayed-or-unpartnered trajectory. Prosocial behaviors were consistently linked with earlier and more sustained partnership trajectories. Three ‘stable partnered’ trajectories were identified. Participants in these groups tended to remain partnered once partnering had begun, though the age of first partnering differed between them, and to have more favorable educational and economic outcomes. They had higher personal and household earnings and were more likely to have children living in the home. Participants in the delayed-or-unpartnered and early-separated groups, in contrast, who, respectively, comprised 30.0% and 15.5% of the sample, fared poorly.» (p. 846) Thus, results reveal «that participants with partnership difficulties were much more likely to have lower earnings and to be in receipt of welfare, when compared with partnered participants. In contrast to childhood problem behaviors, prosocial traits have been linked with better social integration and academic attainment in childhood […], and higher earnings and perceived attractiveness in adulthood […], and would therefore be expected to enhance partnership opportunities including the capacity to attract new partners following separation.» (p. 849)
