Youth Internalizing Problems and Changes in Parent-Child Relationships Across Early Adolescence: Lability and Developmental Trends

Annual Research Review: The power of predictability - patterns of signals in early life shape neurodevelopment and mental health trajectories

The global burden of early life adversity (ELA) is profound. The World Health Organization has estimated that ELA accounts for almost 30% of all psychiatric cases. Yet, our ability to identify which individuals exposed to ELA will develop mental illness remains poor and there is a critical need to identify underlying pathways and mechanisms. This review proposes unpredictability as an understudied aspect of ELA that is tractable and presents a conceptual model that includes biologically plausible mechanistic pathways by which unpredictability impacts the developing brain. The model is supported by a synthesis of published and new data illustrating the significant impacts of patterns of signals on child development. We begin with an overview of the existing unpredictability literature, which has focused primarily on longer patterns of unpredictability (e.g. years, months, and days). We then describe our work testing the impact of patterns of parental signals on a moment-to-moment timescale, providing evidence that patterns of these signals during sensitive windows of development influence neurocircuit formation across species and thus may be an evolutionarily conserved process that shapes the developing brain. Next, attention is drawn to emerging themes which provide a framework for future directions of research including the evaluation of functions, such as effortful control, that may be particularly vulnerable to unpredictability, sensitive periods, sex differences, cross-cultural investigations, addressing causality, and unpredictability as a pathway by which other forms of ELA impact development. Finally, we provide suggestions for prevention and intervention, including the introduction of a screening instrument for the identification of children exposed to unpredictable experiences.

Childhood unpredictability research within the developmental psychopathology framework: Advances, implications, and future directions

Greater unpredictability in childhood from the level of the caregiver-child dyad to broader family, home, or environmental instability is consistently associated with disruptions in cognitive, socioemotional, behavioral, and biological development in humans. These findings are bolstered by experimental research in non-human animal models suggesting that early life unpredictability is an important environmental signal to the developing organism that shapes neurodevelopment and behavior. Research on childhood unpredictability has surged in the past several years, guided in part by theoretical grounding from the developmental psychopathology framework (shaped largely by Dr. Dante Cicchetti's innovative work). The current review focuses on future directions for unpredictability research, including probing intergenerational effects, the role of predictability in resilience, cultural and contextual considerations, and novel developmental outcomes that should be tested in relation to childhood unpredictability. We urge the integration of multidisciplinary perspectives and collaborations into future research on unpredictability. We also provide ideas for translating this research to real-world practice and policy and encourage high-quality research testing whether incorporating predictability into interventions and policy improves developmental outcomes, which would support further dissemination of these findings.

Intraindividual variability in parental acceptance-rejection predicts externalizing and internalizing symptoms across childhood/adolescence in nine countries

Parenting that is high in rejection and low in acceptance is associated with higher levels of internalizing (INT) and externalizing (EXT) problems in children and adolescents. These symptoms develop and can increase in severity to negatively impact adolescents' social, academic, and emotional functioning. However, there are two major gaps in the extant literature: (a) nearly all prior research has focused on between-person differences in acceptance/rejection at the expense of examining intraindividual variability (IIV) across time in acceptance/rejection; and (b) no prior studies examine IIV in acceptance/rejection in diverse international samples. The present study utilized six waves of data with 1,199 adolescents' families living in nine countries from the Parenting Across Cultures study to test the hypotheses that (1) higher amounts of youth IIV in mother acceptance/rejection predict higher internalizing and (2) externalizing symptoms, and (3) that higher youth IIV in father acceptance/rejection predict higher internalizing, and (4) externalizing symptoms. Meta-analytic techniques indicated a significant, positive effect of IIV in child-reported mother and father acceptance/rejection on adolescent externalizing symptoms, and a significant positive effect of IIV in father acceptance/rejection on internalizing symptoms. The weighted effect for mother acceptance/rejection on internalizing symptoms was not statistically significant. Additionally, there was significant heterogeneity in all meta-analytic estimates. More variability over time in experiences of parental acceptance/rejection predicts internalizing and externalizing symptoms as children transition into adolescence, and this effect is present across multiple diverse samples.

Across ages and places: Unpredictability of maternal sensory signals and child internalizing behaviors

BACKGROUND

Patterns of sensory inputs early in life play an integral role in shaping the maturation of neural circuits, including those implicated in emotion and cognition. In both experimental animal models and observational human research, unpredictable sensory signals have been linked to aberrant developmental outcomes, including poor memory and effortful control. These findings suggest that sensitivity to unpredictable sensory signals is conserved across species and sculpts the developing brain. The current study provides a novel investigation of unpredictable maternal sensory signals in early life and child internalizing behaviors. We tested these associations in three independent cohorts to probe the generalizability of associations across continents and cultures.

METHOD

The three prospective longitudinal cohorts were based in Orange, USA (n = 163, 47.2 % female, Mage = 1 year); Turku, Finland (n = 239, 44.8 % female, Mage = 5 years); and Irvine, USA (n = 129, 43.4 % female, Mage = 9.6 years). Unpredictability of maternal sensory signals was quantified during free-play interactions. Child internalizing behaviors were measured via parent report (Orange & Turku) and child self-report (Irvine).

RESULTS

Early life exposure to unpredictable maternal sensory signals was associated with greater child fearfulness/anxiety in all three cohorts, above and beyond maternal sensitivity and sociodemographic factors. The association between unpredictable maternal sensory signals and child sadness/depression was relatively weaker and did not reach traditional thresholds for statistical significance.

LIMITATIONS

The correlational design limits our ability to make causal inferences.

CONCLUSIONS

Findings across the three diverse cohorts suggest that unpredictable maternal signals early in life shape the development of internalizing behaviors, particularly fearfulness and anxiety.

Bullying Victimization and Internalizing Problems among Adolescents: A Moderated Mediation Model of Peer Autonomy Support and Self-Esteem

The present study employed the social-ecological diathesis-stress model as a theoretical framework to extend previous research by examining the underlying mechanism and conditional process that contribute to the positive association between bullying victimization and internalizing problems among adolescents. A moderated mediation model involving peer autonomy support and self-esteem was tested using a sample of 1723 adolescents (50.7% girls; M age = 12.79, SD = 1.58), who completed questionnaires assessing internalizing problems, bullying victimization, peer autonomy support, and self-esteem. The findings revealed that self-esteem partially mediated the positive association between bullying victimization and adolescents' internalizing problems. Specifically, bullying victimization was inversely related to self-esteem, which, in turn, was negatively associated with internalizing problems. Further moderation analyses demonstrated that these direct and indirect associations varied based on levels of peer autonomy support. Simple slope analyses specifically indicated that (a) peer autonomy support buffered against the negative association of bullying victimization with self-esteem and internalizing problems, and (b) peer autonomy support mitigated the negative association of self-esteem with internalizing problems. The elucidation of this mechanism and conditional process holds important implications for early interventions and prevention efforts aimed at mitigating the detrimental association of bullying victimization with adolescents' healthy emotional functions.

Association between Electronic Media Use and Internalizing Problems: The Mediating Effect of Parent-Child Conflict and Moderating Effect of Children's Age

In today's digital world, children are exposed extensively to electronic media, making it an integral part of their daily lives. However, excessive use of electronic media during childhood has been associated with various internalizing problems. Moreover, parent-child conflict and children's age may be closely associated with children's problem behaviors. The current study employed a cross-sectional design and conducted a questionnaire survey of 711 parents to examine the association between children's electronic media use and their internalizing problems. Furthermore, this study probed the mediating role of parent-child conflict within this association and the moderating effect of children's age. The results of structural equation modeling showed a positive correlation between children's use of electronic media and their internalizing difficulties. Parent-child conflict served as a mediating factor in this association. Results also showed that the association between parent-child conflict and internalizing problems becomes more pronounced as children grow older. These findings imply that parents should encourage their children to develop healthy habits in using electronic media while fostering positive relationships. Parents should also be mindful of the psychological changes as children age and provide guidance to help them become proficient digital citizens.

Development of the Japanese Parenting Style Scale and examination of its validity and reliability

Parenting is an essential factor affecting child development. Therefore, several studies have focused on individual differences in parenting (i.e., parenting styles). However, there exist only a few useful scales in Japan, especially for parents who have preschool children. Therefore, a new scale for assessing parenting styles in Japan, based on the traditional theoretical framework, was developed, and examined for its validity and reliability. In Study 1, 82 original items were constructed and 1236 parents with preschool children completed these items. Next, 28 items for the Japanese Parenting Style Scale (JPSS) were selected based on factor analysis and the analyses of the graded response model. The JPSS included four factors: warmth, hostility, permissiveness, and harsh control. The results showed that each sub-scale had sufficient conceptual validity and internal consistency. In Study 2, the criterion-related validity of the JPSS was examined. A total of 1236 parents, non-participants in Study 1, completed the JPSS and other scales. The results showed sufficient criterion-related validity for the scale.

Characterizing Parent–Child Interactions in Families of Autistic Children in Late Childhood

Parent–child interactions are influential to a wide range of positive developmental processes in neurotypical children, yet contributions to our understanding of these interactions using observational methods in families of children on the autism spectrum are lacking. The aim of the current study is to investigate how autism symptoms might impact these interactions. We use a family discussion task to: (1) compare families of autistic children aged 8–12 years (n = 21) to families of typically developing children (n = 21, matched on age and cognitive abilities) on the observed levels of supportive and directive behaviors in the parent–child relationship, and (2) examine the associations between parent–child interaction characteristics and child functioning. Results showed no differences in the observed levels of supportive behavior exhibited by parents, but significantly less supportive behavior in autistic children compared to neurotypical children. In addition, parents of autistic children had higher levels of observed directive behavior compared to parents of neurotypical children. Levels of supportive behavior in parents and autistic children were negatively associated with child ADHD symptoms. Findings reinforce literature on younger children describing positive parenting characteristics and further rebuke historical accounts of negative parenting qualities of parents of autistic children.

The Roles of Gender and Parenting in the relations between Racial Discrimination Experiences and Problem Behaviors among African American Adolescents

The goal of this study was to examine whether, in African American families with adolescents, the associations between adolescents' racial discrimination experiences and adolescents' internalizing and externalizing problem behaviors differed based on involved-vigilant parenting and the genders of the parent and child. The sample included 567 African American parents of adolescents who completed an online survey on parenting, race-related stressors, and adolescent outcomes. Path analyses examining main effects and the interaction between adolescents' racial discrimination experiences, as reported by the parent, and involved-vigilant parenting were conducted in MPlus 8.2. Multigroup analyses by the gender pairing of the parent and target child were also conducted. Adolescent racial discrimination experiences were positively related to internalizing and externalizing problem behaviors. Multigroup analyses indicated that high maternal involved-vigilant parenting buffered the association between girls' racial discrimination experiences and problem behaviors whereas high paternal involved-vigilant parenting buffered the association between boys' racial discrimination experiences and problem behaviors. Overall, the results indicated that when adolescents experienced high levels of racial discrimination, involved vigilant parenting was protective for problem behaviors when received from same gender parents. Involved-vigilant parenting was compensatory when received from cross-gender parents.
