Francis Vergunst Hello. My name is Francis Vergunst, I’m a Post-Doctoral Researcher at University of Montreal. I’m going to talk about some of our recent research linking behaviors in childhood through adult life partnering patterns, published in JCPP. So we know that most people will partner during their lives. Cross cultural studies show that people spend a large amount of time talking about romantic partnerships, and this is also well evidenced in popular culture, including music, literature, cinema, and innumerable TV series. Partnership is an important source of social, emotional, and practical support, and is also associated with improved health and wellbeing. So longitudinal studies have consistently shown that people who are married or cohabiting, typically, live healthier, longer lives. So there’s a lot of interest in what factors might predict partnering success, and personality traits like conscientiousness, emotional stability, warmth, and trust have all been shown to matter. We also know, from the psychiatric literature, that children with behavioral problems, like ADHD and conduct disorder, are more likely to experience romantic partnering difficulties as adults, including inter-partner conflict and violence. So we were interested in whether there was an association between behavioral problems or difficulties in childhood and adult life partnering patterns, in population based samples, so people without clinical diagnoses. Our study had two aims. And the first was to describe patterns of romantic partnering from aged 18 to 35, in a large population based sample of males and females, based on their tax return records. And second, to examine the association between childhood behaviors and adult life partnering patterns. So how did we do this? The study involved nearly 3,000 Canadian children who were assessed at age 10, 11, 12, by their school teachers, for behaviors like inattention, hyperactivity, aggression, opposition, anxiety, as well as pro-social behaviors, and then followed up for 30 years. We then linked the behavioral ratings to the participants tax return records, and this included information about whether the participant was married or cohabiting for each year of follow up. Next we used a statistical procedure called ‘group-based trajectory modeling’, which allowed us to identify distinct patterns of partnering across adulthood. And then…we then linked the behavioral assessments in childhood to these patterns of partnering. So what did we find? Here you can see the results of the statistical modeling procedure from age 18 to 35. On the horizontal axis you can see participants age in years. And on the vertical axis you can see the probability of being partnered. We see that were five distinct groups of partnering. Most participants started partnering in their early and mid-20s, the grey, light blue, and dark blue groups. And around 15% of participants partnered early but then separated and returned to unpartnered status in their early 30s. Finally, about 30% of the sample remained unpartnered predominantly, from age 18 to 35. We see that participants who separated early, the ones in the yellow group, and who were unpartnered, in the red group, were also more likely to have left high school without a Diploma, to have lower earnings, and also have higher welfare receipt across adulthood. So what did we find once we linked these trajectories to the behavioral problems in childhood? Well three main things. First, we found that children who were aggressive, oppositional, as rated by teachers, at age 10, 11, and 12, were more likely to separate and return to unpartnered status in early adulthood. Second, we found that children who were rated by teachers as being anxious were more likely to be unpartnered from age 18 to 35. And third, we found that children who were pro-social, i.e. those rated as being kind, helpful, and considerate, were more likely to show earlier and more sustained partnering across early adulthood. So what do these findings mean? The study shows that behaviors in childhood are associated with distinct patterns of partnering across early adulthood, in population based samples, without clinical diagnoses. There are several explanations for this. First, we know that behaviors are relatively stable across development, so traits like aggression or anxiety could persist into adulthood and influence the formation of romantic partnerships. After all, people who are distractive, or argumentative, or anxious, or less fun to spend time with, on average, and this could influence partnering decisions. Second, it’s also possible that several indirect pathways could explain the effect, for example, studies show that children who exhibit disruptive behaviors are more likely to misuse substances, engage in antisocial behavior, and to fail to graduate high school, to have lower earnings, and so on. All of which have knock on effects on the capacity to attract and maintain romantic partnerships in adulthood. So in summary, children with behavioral difficulties face many challenges that cascade across their lives. We suggest that early monitoring and support and prevention programmes can reduce behavioral problems, and promote pro-social traits, and improve outcomes, including partnering prospects, which should have benefits for both individuals and for society. Thanks for watching.
