Facing infant cuteness: How nurturing care motivation and oxytocin system gene methylation are associated with responses to baby schema features.

Baby schema features are a specific set of physical features-including chubby cheeks, large, low-set eyes, and a large, round head-that have evolutionary adaptive value in their ability to trigger nurturant care. In this study among nulliparous women (N = 81; M age = 23.60, SD = 0.44), we examined how sensitivity to these baby schema features differs based on individual variations in nurturant care motivation and oxytocin system gene methylation. We integrated subjective ratings with measures of facial expressions and electroencephalography (EEG) in response to infant faces that were manipulated to contain more or less pronounced baby schema features. Linear mixed effects analyses demonstrated that infants with more pronounced baby schema features were rated as cuter and participants indicated greater motivation to take care of them. Furthermore, infants with more pronounced baby schema features elicited stronger smiling responses and enhanced P2 and LPP amplitudes compared to infants with less pronounced baby schema features. Importantly, individual differences significantly predicted baby schema effects. Specifically, women with low OXTR methylation and high nurturance motivation showed enhanced differentiation in automatic neurophysiological responses to infants with high and low levels of baby schema features. These findings highlight the importance of considering individual differences in continued research to further understand the complexities of sensitivity to child cues, including facial features, which will improve our understanding of the intricate neurobiological system that forms the basis of caregiving behavior.

Parents' and classmates' influences on adolescents' ethnic prejudice: A longitudinal multi-informant study.

The family and classroom are important contexts that can contribute to the socialization of ethnic prejudice. However, less is known about their unique, relative, and synergic contributions in influencing youth's affective and cognitive prejudice. The current longitudinal study examined these processes and possible moderators among 688 Italian youth (49.13% girls; Mage = 15.61 years), their parents (nmothers = 603, nfathers = 471; Mage = 49.51 years), and classmates between January/February 2022 and January/February 2023. Cross-lagged panel models highlighted that parents and classmates exert unique and relative influences on different dimensions of adolescents' prejudice. Additionally, different interaction effects also emerged for affective (i.e., adverse compensatory effect) and cognitive (i.e., amplifying effect) prejudice. Thus, adolescents draw from the multiple contexts of development to orient themselves in the social world.

Effectiveness of a multidisciplinary treatment with youth-initiated mentoring for youths with mental health needs from multi-problem families: a quasi-experimental study.

BACKGROUND: Children from multi-problem families have an increased risk for experiencing mental health problems. These families face problems in several domains that are often found to be chronic and intergenerational. Yet, the effects of mental health care for youths from multi-problem families are small at best, urging research on new treatment programs. The InConnection approach is an integrated care program to improve resilience of youths with mental health needs from multi-problem families by connecting professional expertise from multiple disciplines with the informal social network of the youth. Youths are asked to nominate a youth-initiated mentor (YIM) from the supportive adults in their network. METHODS: This quasi-experimental study compared the effectiveness of the InConnection approach to treatment as usual in a sample of 107 families (n = 66 intervention group, n = 41 control group) with n = 115 youths receiving treatment (cases). Youths (n = 102 reports, Mage = 15.59 years), parents (n = 85 reports) and case managers (n = 107 reports) responded to questionnaires four times over 15 months. Using these data, we measured youth resilience as the primary outcome, seven secondary outcomes, and three intermediate outcomes. RESULTS: Latent growth models showed only one significant change in outcomes over time across conditions, namely a decrease in case manager-reported child unsafety, and only two condition effects, which were both parent-reported. Parents in the InConnection group reported improvements over time in youth's emotional and behavioral problems and their own positive parenting, whereas control parents reported no changes (ps ≤ 0.013). DISCUSSION: The treatment conditions were not effective in improving most of the youth and parental outcomes over time, except for child safety reported by the case manager. The InConnection approach only outperformed care as usual on two parent-reported outcomes. Future research should examine for whom and under what circumstances the InConnection approach works more convincingly. TRIAL REGISTRATION: Netherlands Trial Register NL7565.

Adolescents' belonging in post-divorce families: Examining residential and digital contact with mothers and fathers.

Using data of 166 adolescents from divorced families, this study examined longitudinal associations between the quantity and quality of adolescents' residential contact and digital contact with parents, and their sense of family belonging. Cross-lagged panel models showed concurrent associations among adolescents' residential and digital contact with each parent, yet positively for fathers and negatively for mothers. Some cross-lagged paths revealed that higher-quality interactions may contribute to positive changes in contact. Although there were effects of parent-adolescent contact on family belongingness, over time belongingness was mostly predicted by the general quality of contact. The results suggest that post-divorce relationships require frequent and meaningful time together, the effects of which, however, do hardly transfer over time in terms of adolescents' belongingness.

Parental SES and family support as predictors of educational level: Testing the buffering effect of effortful control and peer support.

INTRODUCTION: Exposure to family risk factors increases adolescents' chances of attaining a lower educational level. However, some adolescents attain a high educational level despite being exposed to family risk factors such as a lower parental socioeconomic status (SES) or receiving less family support. METHOD: Using data from the Dutch TRAILS cohort study (NT1 = 2175; Mage = 11.1, SD = 0.55, 50.8% female), we investigated if higher levels of effortful control and peer support can buffer against the negative effects of a lower parental SES and less family support on educational level. Two multinomial logistic regressions were performed (from early to mid-adolescence and from mid-adolescence to young adulthood) with post hoc tests to contrast four ordinal educational levels: practical vocational, theoretical vocational, higher general, and (pre-)university. RESULTS: Adolescents with a higher parental SES were consistently more likely to end up at a higher educational level, but family support was hardly associated with educational level. Neither effortful control nor peer support buffered the associations of parental SES and family support with educational level. Effortful control did have a positive direct (compensatory) effect on the educational level. CONCLUSION: We conclude that other individual competencies or more structural changes may be more helpful buffers for reducing socioeconomic inequalities in educational attainment.

The Longitudinal Associations Between Parental Autonomy Support, Autonomy and Peer Resistance.

Adolescents' autonomy is considered to be shaped within family and peer contexts. However, the specific dynamics of the within-person associations between parental autonomy support, adolescents' general autonomy, and peer resistance over time remain unclear. To address this, random-intercept cross-lagged panel models were employed in a sample of 290 Dutch youth in early adolescence (Mage = 11.58, SD = 0.44 at T1; 49.3% boys) and 220 Dutch youth in middle to late adolescence (Mage = 17.79, SD = 1.47 at T1; 25.0% boys), who were followed over two years across four time points. Results showed that changes in adolescents' general autonomy were concurrently associated with changes in their parental autonomy support and peer resistance at the within-person level. However, these associations were not observed longitudinally over a six-month period. These findings suggest that increases in supportive parenting and peer resistance co-occur with increases in adolescents' autonomy within individuals.

Changes in Adolescents' COVID-19-Health-Related Stress, Parent-Adolescent Relationships, and Mental Health During the COVID-19 Pandemic: The Effect of Personality Traits.

Previous studies investigated short-term effects of COVID-19 on families. However, much is unknown about how families with adolescents fared throughout the pandemic, as well as factors that might explain interindividual differences in adjustment. The current study used latent change score models to investigate associations between changes in adolescents' mental health, parent-adolescent relationship quality, and COVID-19-health-related stress from Fall 2019 to Spring 2021, and whether personality predicted changes in adolescents' mental health, relationship quality, and stress. Participants were 242 adolescents (Mage = 11.56, SD = 0.44, 50% girls). Parent-adolescent negative interactions decreased from before the pandemic to the first lockdown, and stronger decreases (both in this period and between Fall 2020 and Spring 2021) were associated with simultaneous stronger increases in mental health. From Spring to Fall 2020, decreases in stress were stronger for less extraverted adolescents and were associated with better mental health. More agreeable adolescents reported a stronger decrease in stress between Fall 2020 and Spring 2021. The findings suggest that it is important to consider heterogeneity in designing future intervention and prevention programs. Especially adolescents with existing problems and from multi-problem families might be at risk for adverse consequences during pandemic-like situations.

Navigating Across Heritage and Destination Cultures: How Personal Identity and Social Identification Processes Relate to Domain-Specific Acculturation Orientations in Adolescence.

Personal identity and social identification processes can be challenging for adolescents belonging to an ethnic minority, who have to cope with the acculturation task of navigating several (and often conflictual) alternatives put forth by their cultural heritage community and destination society. Because identity and acculturation tasks are embedded in core domains of adolescents' life, this three-wave longitudinal study with ethnic minority adolescents (N = 244, 43.4% male; Mage = 14.9) examined how personal identity processes and social identifications are related to acculturation orientations in the education and friendship domains. Results of traditional cross-lagged models showed that, in the educational domain, adolescents who scored higher on cultural heritage maintenance compared to their peers, scored higher on commitment later on. In the friendship domain, stronger associations were found, such that adolescents who scored higher on cultural heritage maintenance compared to their peers, reported higher commitment and in-depth exploration later on, while those who scored higher on identification with friends reported over time also higher cultural heritage maintenance and destination culture adoption. Random-intercept crossed-lagged models indicated that, when adolescents reported above their own average on reconsideration of educational commitment, they reported increased cultural heritage maintenance later on. Furthermore, consistent associations (at baseline and over time) emerged. Overall, this study points to virtuous alliances between the fulfillment of tasks related to adolescents' identity development and acculturation.

Daily and Half-yearly Associations between Boundary Diffusion and Parent-adolescent Relationship Quality after Divorce.

Boundary diffusion is a particular risk after divorce and has been associated with adolescents' adjustment problems. Yet, its potential impact on parent-adolescent relationship quality is less straightforward, as previous findings support both an alienation and conflict perspective. Therefore these associations (daily and half-yearly) were examined in recently divorced families, addressing both within-dyad changes and between-dyad differences. Data were collected among a sample of N = 133 (pre)adolescents (Mage = 11.76; 51.5% boys) from 76 divorced families, using a measurement burst design: Every six months, 14 consecutive days of daily diaries were collected, for 5 waves. Between dyads, adolescents who experienced more boundary diffusion than others, also reported more conflict with both their parents. Within dyads, when adolescents experienced more boundary diffusion than usual by one of their parents (actor), warmth decreased and conflict increased between this parent and the adolescent, that same and the following day. Adolescents also engaged in more conflict with the other parent that day. These findings mostly supported the conflict perspective: Post-divorce boundary diffusion appears to be a general risk factor for parent-adolescent conflict with both parents, and from day-to-day boundary diffusion was linked to a deteriorated parent-adolescent relationship quality, especially with the parent that triangulated or parentified them. There were no significant long-term associations, nor did any moderator (age, gender, living arrangement) explain heterogeneity in effects.

Parenting, Coparenting, and Adolescents' Sense of Autonomy and Belonging After Divorce.

Although there is ample evidence on the importance of experiencing autonomy and belonging for positive adolescent development and the supporting role of parents in this regard, most knowledge stems from intact families. As many youth grow up with divorced parents, this study tested longitudinal links between warm and autonomy supportive parenting and coparental cooperation and conflict on the one hand, and adolescents' post-divorce autonomy and belonging on the other. Data consisted of three-wave self-report data of 191 Dutch adolescents (Mage = 14.36, 61.3% girls) and 227 divorced parents (Mage = 46.08, 74% mothers). Random-intercept cross-lagged panel models showed stable between-family differences, with autonomy relating positively to coparenting and parental autonomy support, and belongingness associating positively solely with parenting. No significant effects were found within families, meaning that changes in (co)parental behaviors did not predict adolescents' experiences of autonomy and belonging or vice versa.

Peer Bullying Victimization Trajectories for Sexually and Gender Diverse Youth from Early Childhood to Late Adolescence.

Sexually and gender diverse (SGD) youth experience more peer bullying victimization than heterosexual, cisgender youth during adolescence, yet the emergence and persistence of these disparities remain underexplored. Also, it is unclear which factors are associated with these disparities across development, and how these disparities are linked to late adolescent health discrepancies. This study utilized the sample from the Millennium Cohort Study in Britain (N = 10,080; 51.3% assigned female at birth; Mage = 2.28, SDage = 0.46 at Wave 2), in which 23.74% of youth reported non-heterosexual attraction, 21.59% reported non-heterosexual identity, and 1.08% reported gender identity not in line with the sex assigned at birth. Using latent class growth modeling, four peer bullying victimization trajectories were identified, with early peak (7.2%), late childhood peak (6.3%), adolescence onset (12.8%), and low (73.6%) rates of victimization. SGD youth, compared to heterosexual and cisgender youth, were found to have increased odds of being in the victimization-involved classes, especially the adolescence onset class. The study further revealed that SGD youth reported more mental health and relational difficulties in childhood, which were linked to their heightened risk of longer-lasting victimization. Further, long-term victimization was found to partially account for the disparities in health and well-being for SGD youth in late adolescence. In conclusion, SGD youth were more likely to experience longer-lasting bullying victimization during childhood and adolescence, its related mental and relational vulnerabilities were already established in childhood, and such victimization disparities were further linked to their detrimental health and well-being in late adolescence.

Longitudinal Associations Between Support and Prosocial Behavior Across Adolescence: The Roles of Fathers, Mothers, Siblings, and Friends.

Family members and friends can play an important role in adolescents' prosocial behavior. To better understand the relation between support and prosocial behavior in adolescence, it's important to conduct longitudinal studies that distinguish between within-dyad variance and between-dyad variance. The current study investigated longitudinal associations between adolescents' prosocial behavior, autonomy support, and emotional support from family and friends across adolescence. Across six annual years, 497 Dutch adolescents (284 boys; mean age T1 = 13.03 years, SDage = 0.46), fathers, mothers, siblings, and friends reported on their prosocial behavior. Adolescents also reported on perceived autonomy and emotional support. Between-dyads almost all associations of support and prosocial behavior of family members and friends with adolescents' prosocial behavior were significant, with higher levels of adolescents' prosocial behavior being associated with higher levels of prosocial behavior and support from fathers, mothers and friends. Within-dyads, several concurrent associations were significant, but within-dyads links between prosocial behavior and autonomy support are particularly driven by adolescent-mother or adolescent-sibling effects. This study highlights processes that occurred either at the between-dyad level or at the within-dyad level, but that varied per relationship type and that adolescents are the main catalysts in within-dyads changes in prosocial behavior and support.

Neurobiological correlates of antisociality across adolescence and young adulthood: a multi-sample, multi-method study.

BACKGROUND: Antisociality across adolescence and young adulthood puts individuals at high risk of developing a variety of problems. Prior research has linked antisociality to autonomic nervous system and endocrinological functioning. However, there is large heterogeneity in antisocial behaviors, and these neurobiological measures are rarely studied conjointly, limited to small specific studies with narrow age ranges, and yield mixed findings due to the type of behavior examined. METHODS: We harmonized data from 1489 participants (9-27 years, 67% male), from six heterogeneous samples. In the resulting dataset, we tested relations between distinct dimensions of antisociality and heart rate, pre-ejection period (PEP), respiratory sinus arrhythmia, respiration rate, skin conductance levels, testosterone, basal cortisol, and the cortisol awakening response (CAR), and test the role of age throughout adolescence and young adulthood. RESULTS: Three dimensions of antisociality were uncovered: 'callous-unemotional (CU)/manipulative traits', 'intentional aggression/conduct', and 'reactivity/impulsivity/irritability'. Shorter PEPs and higher testosterone were related to CU/manipulative traits, and a higher CAR is related to both CU/manipulative traits and intentional aggression/conduct. These effects were stable across age. CONCLUSIONS: Across a heterogeneous sample and consistent across development, the CAR may be a valuable measure to link to CU/manipulative traits and intentional aggression, while sympathetic arousal and testosterone are additionally valuable to understand CU/manipulative traits. Together, these findings deepen our understanding of the fundamental mechanisms underlying different components of antisociality. Finally, we illustrate the potential of using current statistical techniques for combining multiple datasets to draw robust conclusions about biobehavioral associations.

Negative parenting, epigenetic age, and psychological problems: prospective associations from adolescence to young adulthood.

BACKGROUND: Epigenetic clocks are based on DNA methylation levels of several genomic loci and have been developed as indices of biological aging. Studies examining the effects of stressful environmental exposures have shown that stress is associated with differences between epigenetic age and chronological age (i.e., Epigenetic Age acceleration, EA). This pre-registered longitudinal study examined the long-term effects of negative parenting and psychological problems throughout adolescence (ages 13-17 years) on EA in late adolescence (age 17 years) and EA changes from late adolescence to young adulthood (age 25 years). Further, it examined how (change in) EA is related to changes in psychological problems from adolescence to young adulthood. METHODS: We used data from a sample of 434 participants followed from age 13 to age 25, with saliva collected at ages 17 and 25. We estimated EA using four commonly used epigenetic clocks and analyzed the data using Structural Equation Modeling. RESULTS: While negative parenting was not related to EA nor change in EA, (change in) EA was related to developmental indices such as externalizing problems and self-concept clarity. CONCLUSIONS: Declining psychological well-being during young adulthood was preceded by EA.

The future is present in the past: A meta-analysis on the longitudinal associations of parent-adolescent relationships with peer and romantic relationships.

Positive peer and romantic relationships are crucial for adolescents' positive adjustment and relationships with parents lay the foundation for these relationships. This longitudinal meta-analysis examined how parent-adolescent relationships continue into later peer and romantic relationships. Included longitudinal studies (k = 54 involving peer relationships, k = 38 involving romantic relationships) contained demographically diverse samples from predominantly Western cultural contexts. Multilevel meta-regressions indicated that supportive and negative parent-adolescent relationships were associated with supportive and negative future peer and romantic relationships. Meta-analytic structural equation modeling (k = 54) indicated that supportive parent-adolescent relationships unidirectionally predicted supportive and negative peer relationships, while negative parent-adolescent relationships were bidirectionally associated with supportive and negative peer relationships. Maintaining mutually supportive relationships with parents may help adolescents to develop positive social relationships.

Examining Secondary School Choice Processes as a Predictor of Adjustment After the School Transition.

The secondary school transition is an important moment in adolescents' lives. Taking a prospective approach, the present study examined whether educational identity regarding a secondary school choice and own and parental expectations during the last year of primary school predicted post-transition school and psychological adjustment in Dutch adolescents (N = 314, Mage = 11.58). Additionally, the study qualitatively examined the reasons adolescents gave for their school choice, and linked these reasons to exploration behavior and post-transition adjustment. Identity processes and expectations predicted adjustment. Adolescents mostly reported multiple reasons for their school choice, with educational, practical, and social aspects of secondary schools appearing most important. The number of reasons mentioned was associated with pre-transition exploration behavior.

Longitudinal associations of parental psychological control and friend support with autonomy during early adolescence.

Although theories suggest transactional associations between adolescents' autonomy and relationships with parents and friends, few studies have examined these within-person effects. This longitudinal study examined the within-person co-development of adolescents' autonomy and relationships with parents and friends. Adolescents (N = 244 Mage = 11.54, SD = 0.43 at T1; 50% boys) participated in a four-wave study across 2 years in the Netherlands. In random-intercept cross-lagged panel models, within-person results showed that higher levels of autonomy predicted less parental psychological control but not vice versa. However, no lagged-effects between friend support and autonomy were found. This study suggests that adolescents' autonomy steers changes in parental psychological control.

Educational identity and maternal helicopter parenting: Moderation by the perceptions of environmental threat.

This four-wave study examined longitudinal associations between maternal helicopter parenting and college students' educational identity processes over 1 year, as well as the moderating effects of mothers' perceived environmental threats (i.e., uncertainty and competition). Participants were 349 first-year university students (39.8% male, Mage = 18.20) and their mothers (Mage = 49.10) in Hong Kong. Latent class growth analysis identified two subgroups based on levels of mothers' threat perceptions (i.e., lower vs. higher). Multi-group random-intercept cross-lagged models found that, at the within-person level, students' reconsideration of educational commitments positively predicted helicopter parenting only for mothers with higher threat perceptions. These findings mainly support youth-driven effects on overbearing parenting behaviors. Mothers' threat perceptions might exacerbate these excessive responses to youth's academic turbulence.

Using machine learning to identify early predictors of adolescent emotion regulation development.

As 20% of adolescents develop emotion regulation difficulties, it is important to identify important early predictors thereof. Using the machine learning algorithm SEM-forests, we ranked the importance of (87) candidate variables assessed at age 13 in predicting quadratic latent trajectory models of emotion regulation development from age 14 to 18. Participants were 497 Dutch families. Results indicated that the most important predictors were individual differences (e.g., in personality), aspects of relationship quality and conflict behaviors with parents and peers, and internalizing and externalizing problems. Relatively less important were demographics, bullying, delinquency, substance use, and specific parenting practices-although negative parenting practices ranked higher than positive ones. We discuss implications for theory and interventions, and present an open source risk assessment tool, ERRATA.

Within-family linkages between parental monitoring and adolescents externalizing problems with autonomy support as a moderator.

Parents' monitoring efforts are thought to be effective in reducing children's future externalizing problems. Empirical evidence for this claim, however, is limited, as only few studies have unraveled the temporal ordering of these constructs. The present six-wave longitudinal study contributed to the existing literature by examining within-family linkages between monitoring efforts (behavioral control and solicitation) and adolescents' externalizing behaviors while controlling for between-family differences. In addition, it was assessed whether these associations differed when using child versus parent reports, differed for less versus more autonomy-supportive parents, and differed for fathers' versus mothers' monitoring efforts. Longitudinal data (six annual waves) of 497 adolescents (56.9% boys, Mage at T1 = 13.03, SD = 0.46), their mothers (N = 495, Mage at T1 = 44.41, SD = 4.45), and their fathers (N = 446, Mage at T1 = 46.74, SD = 5.10) of the Dutch study Research on Adolescent Development and Relationships (RADAR) were used. Results showed no evidence for the claim that parents' monitoring efforts predict future externalizing problems. In contrast, we found some evidence for the idea that parents' monitoring efforts change in reaction to changes in externalizing problems; when adolescents reported higher levels of externalizing problems than usual in 1 year, this predicted less behavioral control from mothers in the next year. Linkages between monitoring efforts and externalizing problems did not differ between less or more autonomy-supportive parents. Overall, our findings suggest that monitoring efforts are not effective, but also not damaging, in relation to adolescents' externalizing problems.
