Leveraging data from a longitudinal study of Chinese families (n = 364), this research aims to understand the role of secure base script knowledge as a cognitive mechanism by which early caregiving experiences inform adolescents' friendship quality and feelings of loneliness. Results showed that observed maternal sensitivity at 14 and 24 months…

Latent growth curve modeling was used to investigate the longitudinal link between attachment, effortful control (EC), and maladaptive development during middle childhood. In a community sample, children (Time 1: n = 157; M[subscript age] = 10.91) and their mothers were examined three times over a two-year period. Attachment was operationalized at…

Attachment anxiety is a form of attachment insecurity characterized by chronic worries about rejection and need for reassurance. Given the critical role a sense of security plays in maintaining healthy relationships, individuals high in attachment anxiety tend to struggle in romantic relationships, which carries serious implications for their…

Being securely attached and willing to forgive your partner tends to promote greater relationship success. Though attachment and partner forgiveness are associated cross-sectionally, research has yet to investigate whether and how these positive relationship factors tend to codevelop over time. The current study examined cross-lagged effects and…

Education is considered one of the great equalizers of economic opportunity. However, pre-existing differences in educational access may generate differences in educational investment, which may perpetuate the economic inequalities that education is supposed to mitigate. In this paper, we examine the role of reduced educational investment as a…

This study aimed to examine the effect of attachment security in 17-month-olds on their peer play interactions and behavioural problems at ages 4 and 6 years, respectively, in Korea. By employing structural equation modelling, we analyzed the data of 183 children and their mothers, which were extracted from the Panel Study on Korean Children…

Attachment theory suggests that early experiences with caregivers are carried forward across development in the form of mental representations of attachment experiences. Researchers have investigated at least two representation-based constructs when studying attachment and successful adaptation in adulthood: (a) coherence of autobiographical…

Latent class analysis was performed to identify clusters of items on the Longitudinal Study of Adolescent Health -- School Connectedness Scale among students. Cluster membership was explored by student-reported ethnicity. The sample included students attending Canadian secondary schools in two waves of the COMPASS study: Years 4 (Y4:2015/16)…

The current study represents the first longitudinal investigation of the potential effects of breastfeeding duration on maternal sensitivity over the following decade. This study also examined whether infant attachment security at 24 months would mediate longitudinal relations between breastfeeding duration and changes in maternal sensitivity over…

There is limited research examining stability and change in attachment security in middle childhood. The current study addresses this gap using data from a 3-year longitudinal study. Specifically, we examined stability and change in secure base script knowledge during middle childhood using a sample of 157 children (Wave 1 mean age [M[subscript…

We examined the mediational roles of multiple types of adolescents' emotional security in relations between multiple aspects of the interparental relationship and adolescents' mental health from ages 13 to 16 (N = 392). General marital quality, nonviolent parent conflict, and physical intimate partner violence independently predicted mental…

A longstanding question for attachment theory and research is whether genetically based characteristics of the child influence the development of attachment security and its stability over time. This study attempted to replicate and extend recent findings indicating that the developmental stability of attachment security is moderated by oxytocin…

In January 2017, Trellis launched a nine-month study aimed at better understanding the non-academic challenges that postsecondary students face and the ways they try to meet their basic needs while pursuing academic goals. Working with 11 institutions in Texas and Florida, researchers recruited a cohort of 72 current undergraduate students. Though…

Guided primarily by life history theory, this study was designed to identify how and why early exposure to caregiver intimate relationship instability uniquely predicts children's externalizing symptoms in the context of other dimensions of unpredictability characterized by residential and parental job transitions. Participants included 243…

School composition is a topic that has gained increasing attention from researchers over the past few years, as it has been found that the socio-economic characteristics of students are associated with their achievement. However, most research has been cross-sectional and carried out in industrialised countries. In this study, we use parental…
