The dimensionality of the Conflict Resolution Styles Inventory across age and relationships.

Close interpersonal conflicts between parents and children, marital or romantic partners, and between friends are common, and adjustment in youth and adults depends on how these conflicts are managed. While conflict management is important for relationships and adjustment, the structure of conflict management in adults or in youths has rarely been examined. Knowing how conflict management is structured, and whether this structure changes with age and relationships, is important to understanding what factors influence the development of conflict management skills, and how to intervene. In the current study, we explored the unidimensional vs. multidimensional structure of conflict management in family relationships, friendships and romantic relationships across adolescence and adulthood. The sample consisted of 497 Dutch adolescents (57% boys, Mage = 13.03, SD = 0.46, 11-15 years old) who were followed over 11 years in 9 measurement waves, and their parents, siblings, best friends (six waves), and romantic partner (three waves). First-order factor analyses (CFA) showed that the structure of conflict management is similar for adolescents and adults, across relationships. The results of second-order models, including the theoretical higher dimensions positive/negative conflict management and engagement/disengagement, showed no support for these higher dimensions. The results of bifactor models showed differences between adults and youths: while positive problem solving was part of the general factor of conflict management in adults, it was not part of this general factor in adolescents. The general factor was linked to increases in internalizing and externalizing problems, and with decreases in prosocial behavior. Overall, the bifactor models increased the interpretability and validity of the conflict management measure.

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.

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.

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.

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.

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.

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.

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.

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.

The impact of the COVID-19 pandemic on adolescent mental health across the world.

The global impact of the COVID-19 pandemic on adolescents has been substantial. The current review aimed to summarize the existing literature on the impact of the pandemic on mental health during adolescence, with a specific focus on longitudinal studies. The findings from these studies indicated that many adolescents experienced increased mental health problems, especially those who were already vulnerable prior to the pandemic. Several preexisting factors, such as socioeconomic background and gender, and pandemic-related factors, such as perceived stress and restrictive measures, were identified that contribute to interindividual differences in how adolescents were affected by the pandemic. However, it is crucial to interpret these changes in the context of the ongoing trend of increasing mental health problems among youth over the past decades.

Decline in positive future orientations among adolescents during covid-19: The role of socioeconomic status, parental support, and sense of control.

INTRODUCTION: Before coronavirus disease (covid-19), adolescents from a lower socioeconomic status (SES) background tend to have less positive future orientations, receive less parental support, and have a weaker sense of control than adolescents from a higher SES background. The covid-19 pandemic has potentially increased the socioeconomic gaps in positive future orientations, parental support, and sense of control among adolescents who are currently in vocational education. As societies are aiming to return back to precovid norms, certain groups of adolescents might require more attention for ensuring a stable future than others. METHODS: Two-wave questionnaire data of 689 Dutch adolescents (Mage = 17.8; 56% female) from the Youth Got Talent project was analyzed. Latent Change Score models are a relatively novel approach that allows two-wave data to estimate associations between precovid predictor variables and changes in outcome variables from before to during covid-19 (e.g., SES, positive future orientations, parental support, and sense of control). Analyses were preregistered. RESULTS: The precovid socioeconomic differences in adolescent's positive future orientations and sense of control remained stable during covid-19, whereas the socioeconomic difference in parental support decreased during covid-19. A decline in parental support, an increase in sense of control, and more covid-19 hardships were associated with an increase in future orientations. CONCLUSION: The covid-19 situation has not substantially increased socioeconomic differences in positive future orientations and sense of control, but did decrease socioeconomic differences in parental support among adolescents. Short-term policies should aim to facilitate parental support and positive future orientations to all adolescents who experienced a decline, while also long-term focusing on the more consistent socioeconomic difference in sense of control among adolescents.

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.

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.

Depression Socialization in Early Adolescent Friendships: The Role of Baseline Depressive Symptoms and Autonomous Functioning.

There is mixed evidence for depression socialization, a process by which friends affect each other's level of depressive symptoms. The current study examined whether adolescents' baseline depressive symptoms and three dimensions of autonomous functioning (autonomy, peer resistance, and friend adaptation) make adolescents more or less sensitive to depression socialization, and how these dimensions of autonomous functioning were connected. In this preregistered, two-wave longitudinal study, participants completed questionnaires on depressive symptoms, autonomy, and peer resistance and participated in a task to assess friend adaptation. Participants were 416 Dutch adolescents (Mage = 11.60, 52.8% girls) across 230 close friend dyads. In contrast to expectations, results showed no significant depression socialization nor significant moderation. Furthermore, autonomy and peer resistance were related but distinct constructs, and not related to friend adaptation. These findings suggest that there is no depression socialization in early adolescence, regardless of level of autonomous functioning.

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.

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.

Longitudinal Linkages Between Parent-Child Discrepancies in Reports on Parental Autonomy Support and Informants' Depressive Symptoms.

Although parent-child discrepancies in reports of parenting are known to be associated with child depressive symptoms, the direction of causality is unknown. To address this knowledge gap, this study contributes to existing literature by examining longitudinal within-family linkages between parent-child discrepancies in their reports on autonomy support and depressive symptoms of children, while also assessing these linkages with parents' depressive symptoms. In addition, this study explored whether these linkages differ for father- versus mother-child discrepancies. Longitudinal data (six annual waves) of 497 adolescents (56.9% boys, Mage at T1 = 13.03, SD = 0.46), their mothers (N = 495), and their fathers (N = 446) of the Dutch study Research on Adolescent Development and Relationships (RADAR) were used. Counter to expectations, the results of a Random Intercept Cross-Lagged Panel Model provided no evidence for within-family cross-lagged effects. Instead, stable differences between families explained linkages; in families where children reported on average higher levels of depressive symptoms, children also reported lower levels of autonomy support relative to their parents. There were no associations between parent-child discrepancies and parents' depressive symptoms. Thus, the findings suggest that depressive symptoms are neither a consequence, nor a predictor of parent-child discrepancies in adolescence. The hypotheses and analytical plan of this study were preregistered in a project on the Open Science Framework.

Perceived Support from Best Friends and Depressive Symptoms During Adolescence: Disentangling Personal from Dyadic Level Effects.

Support from best friends is an important interpersonal factor in adolescent depression development but is often studied from an individual perspective in which dyadic effects are overlooked. This study aims to a) test whether differences in support vary at the individual level and are related to individual differences in the development of depressive symptoms, whether these differences vary at the dyadic level and are related to dyadic depression symptom development, or both, b) explore whether these associations are moderated by initial levels of depressive symptoms on the individual and/or dyadic level. Data from 452 adolescents (Mage = 13.03), nested in 226 same-gender friendship dyads (60.6% boy-dyads) who participated in the RADAR-Y project were included. Best friends self-reported annually (2006-2008; 3 waves) on their own depressive symptoms and perceived support from their friend. Multilevel models showed no direct association between support and depression development on the individual or dyadic level. However, the initial level of dyads' depressive symptoms moderated the association between dyadic support and dyads' subsequent depression symptom development. When dyads experienced relatively more initial depressive symptoms, higher levels of dyadic support were associated with relative increasing dyadic depressive symptoms. When dyads experienced relatively few initial depressive symptoms, higher levels of dyadic support were associated with relative decreasing dyadic depressive symptoms. Findings suggest that support from best friends can either protect against or exacerbate the development of depressive symptoms for friends, depending on the initial level of depressive symptoms of the dyad.

Longitudinal links between expressive flexibility and friendship quality in adolescence: The moderating effect of social anxiety.

INTRODUCTION: Expressive flexibility, or the ability to both up- and down-regulate emotional expressions in social interactions, is thought as an indicator and a consequence of healthy interpersonal relationships. The present longitudinal study examined bidirectional associations between expressive flexibility and friendship quality in early adolescence. Since prior research found inconsistent results regarding the adaptiveness of expressive flexibility, which indicated the necessity to consider individual variability in the process, we further tested the potential moderating effect of social anxiety in the links from expressive flexibility to friendship quality. METHODS: Participants from two junior high schools in eastern China (N = 274; 50.4% female; Mage = 13.56) were surveyed at three time points with 6-month intervals. Expressive flexibility, friendship quality, and social anxiety were all assessed via self-reported scales. RESULTS: According to the cross-lagged model results, friendship quality significantly predicted increased expressive flexibility over time. Conversely, the longitudinal association from expressive flexibility to friendship quality was not significant, but the interaction between expressive flexibility and social anxiety significantly predicted later friendship quality. Further analyses via the Johnson-Neyman technique revealed that expressive flexibility only positively predicted friendship quality for adolescents with lower levels of social anxiety. CONCLUSION: Our results suggest that expressive flexibility is not always socially adaptive, so practical interventions that aim to improve youths' social adjustment via expressive flexibility training might need to consider the role of individual characteristics.

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.
