Childhood maltreatment affects adolescent sensitivity to parenting and close friendships in predicting growth in externalizing behavior

Sex-specific joint trajectories of deviant peer affiliation and externalizing problems from middle childhood to early adolescence: the predictive role of family maltreatment

Previous research has shown a strong link between deviant peer affiliation (DPA) and externalizing problems (EXT) among children and adolescents. Little is known about how DPA and EXT develop jointly over time or possible sex differences in their development. This longitudinal study identified sex-specific joint trajectories of DPA and EXT from middle childhood to early adolescence and investigated the predictive role of family maltreatment experiences in joint trajectories of DPA and EXT. A total of 3622 Chinese elementary school students in grades 3 and 4 (Mage = 10, SD = 0.53; 46.5% girls) comprised the sample. Assessments were conducted every six months on five occasions across 2.5 years. Parallel process latent class growth modeling (PP-LCGM) was used to explore the joint trajectories of DPA and EXT for boys and girls separately. The PP-LCGM identified four trajectories for boys: "congruent-low" (78.2%), "congruent-high" (12.40%), "deviant peer affiliation increasing" (6.5%), and "congruent late increasing" (2.9%). Four trajectories were identified for girls: "congruent-low" (82.5%), "slowly increasing" (10.2%), and "deviant peer affiliation desisting" (5.6%), and "congruent late increasing" (1.7%). After controlling for socioeconomic status (SES), the results showed that compared to the congruent-low group, more severe family maltreatment predicted the high and high-start trajectories for boys. The findings highlighted the joint development of DPA and EXT and the sex differences associated with their development. Findings also shed light on the importance of sex in developmental responses to family maltreatment.

Peer Status as a Potential Risk or Protective Factor: A Latent Profile Analysis on Peer Status and Its Association with Internalizing Symptoms in Adolescents with and without Parental Physical Abuse Experience

Research has well established that parental physical abuse experiences can lead to devastating consequences for adolescents, with peer relationships acting as both protective and risk factors. With the person-centered latent profile analysis (LPA), we analyzed questionnaire data from a cross-sectional study in 2020 composed of a sample of 1959 seventh-grade high school students from Switzerland. This study investigated and compared peer-status profiles combining peer acceptance and peer popularity for adolescents with and without parental physical abuse experiences. We conducted a multinomial logistic regression analysis to investigate further depression, anxiety, and dissociation as predictors of profile membership. With LPA, we identified three distinct profiles for adolescents within the subgroup with experiences of parental physical abuse (n = 344), namely liked, liked-popular, and rejected-unpopular. Within the subgroup of adolescents without parental physical abuse experiences (n = 1565), LPA revealed four profiles, namely liked, liked-popular, rejected-unpopular, and average. For adolescents with parental physical abuse experiences, higher levels of dissociation significantly indicated they were more likely to belong to the rejected-unpopular group than belong to the liked group. Anxious students without experiences of parental physical abuse were more likely to belong to the rejected-unpopular and liked profiles than belong to the liked-popular and average profiles. These findings clearly argue for a deeper understanding of the role of parental physical abuse when analyzing the relationship between dissociation and anxiety and peer status. Operationalizing peer status with the four individual dimensions of likeability, rejection, popularity, and unpopularity was valuable in that the role of peer rejection with respect to different internalizing symptoms became apparent.

Childhood psychopathology mediates associations between childhood adversities and multiple health risk behaviours in adolescence: analysis using the ALSPAC birth cohort

BACKGROUND

Childhood adversity strongly predicts adolescent multiple health risk behaviours (MRBs) such as alcohol/tobacco use, self-harm and physical inactivity, and both adversities and MRBs are associated with premature mortality and several chronic health conditions that are among the leading causes of death in adults. It is therefore important to understand the relationship between adversities and MRBs and what could mediate any association. The aim of this study was to explore whether childhood psychopathology mediates associations between adversities and MRBs.

METHODS

Participants were young people in the Avon Longitudinal Study of Parents and Children (ALSPAC) (N = 5,799). Using structural equation modelling, we explored the associations between adversities before 9 years and MRBs at age 16 years. We also explored potential mediating pathways through dimensional psychopathology measured by the Strength and Difficulties Questionnaire subscales at age 12 years.

RESULTS

There were strong positive associations between adversities and MRBs (β .25, 95% CI 0.20, 0.31, p < .001) suggesting that each additional adversity is associated with a 0.25 increase in number of MRBs out of 13 total risk behaviours. We found robust evidence of mediating pathways from adversities through conduct problems (β .05, 95% CI 0.03, 0.06, p < .001), hyperactivity/inattention (β .02, 95% CI 0.01, 0.03, p < .001) and peer relationship problems (β -.02, 95% CI -0.03, -0.02, p < .001) to MRBs.

CONCLUSIONS

Increased conduct problems and hyperactivity/inattention appear to partially explain the relationship between adversities and MRBs. Peer relationship problems also appear to reduce the association between adversities and MRBs, and further research is needed to understand how to encourage peer connectivity without increasing risk of MRBs. These results suggest that interventions aimed at reducing MRBs among those exposed to childhood adversities could focus on prevention of behavioural problems.

The Associations of Polygenic Scores for Risky Behaviors and Parenting Behaviors with Adolescent Externalizing Problems

The current study focused on longitudinal effects of genetics and parental behaviors and their interplay on externalizing behaviors in a panel study following individuals from adolescence to young adulthood. The nationally representative sample of Add Health participants of European ancestry included N = 4142 individuals, measured on three occasions. Parenting was operationalized as experiences with child maltreatment and maternal closeness. Externalizing problems were operationalized as alcohol use, cannabis use, and antisocial behaviors. Genetic effects were operationalized as a polygenic score (PGS) of risky behaviors. The results showed significant effects for child maltreatment, maternal closeness, and PGS, above and beyond other factors and previous levels of externalizing behaviors. Furthermore, maternal closeness was found to negatively correlate with PGS. No significant interaction effects of parenting and PGS were found. The results underscore the joint independent effects of parenting and genetics on the change in externalizing behaviors from adolescence to young adulthood.
