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.

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.

Explaining Heterogeneity of Daily Conflict Spillover in the Family: The Role of Dyadic Marital Conflict Patterns.

In this multi-informant, longitudinal, daily diary study, we investigated whether long-term dyadic patterns of marital conflict resolution explain the heterogeneity in short-term day-to-day cross-lagged associations between marital conflict intensity and mother-adolescent conflict intensity. The sample consisted of 419 adolescents (44.6% girls, Mage = 13.02, SD = 0.44, at T1; Mage = 17.02, SD = 0.44, at T5), their mothers (N = 419, Mage = 44.48, SD = 4.17, at T1), and their fathers (N = 419, Mage = 46.76, SD = 4.99, at T1). Mothers and fathers reported on their marital conflict resolution strategies annually across 5 years. Mother-father daily conflict intensity (mother-reported) and mother-adolescent daily conflict intensity (mother- and adolescent-reported) were assessed for 75 days across 5 years. We hypothesized that long-term marital conflict resolution patterns would moderate the short-term daily dynamics of conflict between the marital and the mother-adolescent dyads. Latent Class Growth Analysis revealed four types of families based on long-term dyadic marital conflict resolution, including families where mostly constructive or mostly destructive conflict resolution was used. Dynamic Structural Equation Modeling was used to investigate the daily levels and short-term daily dynamics of conflict, revealing that for most families there were no day-to-day lagged associations between marital conflict and mother-adolescent conflict. Results showed that long-term conflict resolution patterns did not moderate the short-term dynamics of daily conflict. However, differences among long-term marital conflict resolution patterns were found in the levels of daily conflict, such that in families with long-term destructive conflict resolution patterns, daily conflict intensity was higher.

En este estudio de informantes múltiples, longitudinal y de registro diario, investigamos si los patrones diádicos de resolución de conflictos conyugales a largo plazo explican la heterogeneidad en las asociaciones diarias de retardo cruzado a corto plazo entre la intensidad del conflicto conyugal y la intensidad del conflicto entre las madres y los adolescentes. La muestra estuvo integrada por 419 adolescentes (el 44.6 % niñas, edad promedio = 13.02, desviación típica = 0.44, en la T1; edad promedio = 17.02, desviación típica= 0.44, en la T5), sus madres (número = 419, edad promedio = 44.48, desviación típica = 4.17, en la T1), y sus padres (número = 419, edad promedio= 46.76, desviación típica = 4.99, en la T1). Las madres y los padres informaron sus estrategias de resolución de conflictos conyugales anualmente durante cinco años. Se evaluaron la intensidad del conflicto diario entre la madre y el padre (informado por la madre) y la intensidad del conflicto diario entre la madre y el adolescente (informado por la madre y el adolescente) durante 75 días a lo largo de cinco años. Planteamos la hipótesis de que los patrones de resolución de conflicto conyugal a largo plazo moderarían la dinámica diaria de conflicto a corto plazo entre la díada conyugal y la díada madre-adolescente. El análisis de crecimiento de clases latentes reveló cuatro tipos de familias sobre la base de la resolución de conflictos conyugales diádicos a largo plazo, incluidas las familias donde se usó la resolución de conflictos principalmente constructiva o principalmente destructiva. Se utilizó el modelo de ecuaciones estructurales dinámicas para investigar los niveles diarios y la dinámica diaria de conflicto a corto plazo, el cual reveló que para la mayoría de las familias no hubo asociaciones diarias retardadas entre el conflicto conyugal y el conflicto entre madres y adolescentes. Los resultados indicaron que los patrones de resolución de conflictos a largo plazo no moderaron la dinámica a corto plazo del conflicto diario. Sin embargo, se encontraron diferencias entre los patrones de resolución de conflictos conyugales a largo plazo en los niveles de conflicto diario, de modo que, en las familias con patrones de resolución de conflictos destructivos a largo plazo, la intensidad del conflicto diario fue mayor.

Peer Victimization, Internalizing Problems, and the Buffering Role of Friendship Quality: Disaggregating Between- and Within-Person Associations.

Although many studies have shown an association between peer victimization and internalizing problems, which may be buffered by friendship quality, it is unclear whether these associations apply to within-person processes as well. This would mean that at times when adolescents experience more victimization than they usually do, they also experience more internalizing problems. The current study disaggregated between- and within-person variation to examine the association between peer victimization and symptoms of depression and anxiety, and the protective effect of friend support and conflict. Participants were 497 Dutch adolescents (56% boys) with a mean age of 13.03 (SDage = 0.45, ranging from 11.68 to 15.56 at Wave 1). They participated in a 6-wave questionnaire study, with each wave taking place approximately one year after the previous. The results showed that peer victimization was associated with depressive symptoms and anxiety across adolescence, both between and within persons. Friend support buffered this association at the between-person level, but not the within-person level. This study highlights the impact of peer victimization and suggests that friend support may partly protect adolescents from the effects of peer victimization.

Longitudinal Associations Between Depressive Symptoms and Quality of Romantic Relationships in Late Adolescence.

While youth with higher levels of depressive symptoms appear to have lower quality romantic relationships, little is known about longitudinal associations for both men and women. Therefore, this study used longitudinal dyadic design to examine both concurrent and longitudinal associations between depressive symptoms and positive as well as negative aspects of romantic relationship quality across two waves one- or two-years apart. The sample consisted of 149 Dutch stable heterosexual couples (149 females and 142 males participated at T1) in a stable romantic relationship in late adolescence with a mean age of 20.43 years old at the first wave. Actor-Partner Interdependence models were used to examine potential bidirectional associations over time between depressive symptoms and romantic relationship quality, above and beyond potential concurrent associations and stability of the constructs over time, from the perspective of both romantic partners. Results consistently indicated that men and women who reported higher levels of depressive symptoms perceived less positive aspects (intimacy and support) and more negative aspects (conflict) in their romantic relationship over time. In addition, unexpectedly, when men and women perceived more positive relationship aspects, their partners reported higher levels of depressive symptoms over time. These findings stress that depressive symptoms can interfere with the formation of high-quality romantic relationships.

Commentary: On intimate relationships, adult roles, interplay of family adversity and individual vulnerability, intergenerational transmission, and developmental selection - commentary on Vergunst et al. (2020).

Five developmental trajectories of partnering in the ages 18-35 were identified by Vergunst et al. (2020). In my discussion of these trajectories, I included findings of three studies using the same dataset as Vergunst et al. First I showed that formation and maintenance of intimate relationships have different childhood precursors. It also became clear that family adversity and high inattention in childhood are systematic predictors of problems in investing in age-graded roles in adulthood: in educational attainment, partnering, and becoming economically self-reliant. A limitation of the study Vergunst et al. is the absence of adolescence. Inclusion of data on adolescent development could have clarified why effects of family adversity and childhood traits are very small and provided evidence for the role of parent-adolescent relationships. Finally, the study by Vergunst et al. demonstrates intergenerational transmission of problems across various developmental domains. This intergenerational continuity of vulnerabilities suggests developmental selection.

Identity development across the transition from secondary to tertiary education: A 9-wave longitudinal study.

INTRODUCTION: The transition from secondary to tertiary education could be considered as an opportunity for psychological growth and might play a meaningful role in educational identity development during adolescence. In the present study, we aimed to examine how adolescents differ in their educational identity development across the normative transition from secondary to tertiary education in the Netherlands, and if differences between classes could be described at the socio-demographic, academic, individual, and relational level. METHOD: The present study conducted parallel process piecewise Latent Class Growth Analyses in a sample of 685 Dutch participants (47.0% girls, Mage = 17.29 years old at the time of transition). Longitudinal data from adolescent (bi)annual surveys were centered around the final year of secondary school, with 4 years before the final year and 4 years after. RESULTS: Heterogeneity in the development of identity commitment and reconsideration across the transition was best classified by a 4-class solution. These four classes were labelled Increasing Self-Certainty, Stable Self-Certainty, Post-Transition Uncertainty, and Enduring Uncertainty. Adolescents' patterns of identity development were meaningfully associated with sociodemographic, academic, individual, and relational characteristics. CONCLUSION: The present study discusses the merits of taking a person-centered approach, which indicated adaptive development for the majority of adolescents but also captured distinct patterns of struggles in educational identity development across the transition for a sizable minority.

Polygenic Risk for Major Depression Interacts with Parental Criticism in Predicting Adolescent Depressive Symptom Development.

Research has focused more and more on the interplay between genetics and environment in predicting different forms of psychopathology, including depressive symptoms. While the polygenic nature of depressive symptoms is increasingly recognized, only few studies have applied a polygenic approach in gene-by-environment interaction (G × E) studies. Furthermore, longitudinal G × E studies on developmental psychopathological properties of depression are scarce. Therefore, this 6-year longitudinal community study examined the interaction between genetic risk for major depression and a multi-informant longitudinal index of critical parenting in relation to depressive symptom development from early to late adolescence. The sample consisted of 327 Dutch adolescents of European descent (56% boys; Mage T1 = 13.00, SDage T1 = 0.44). Polygenic risk for major depression was based on the Hyde et al. (Nature Genetics, 48, 1031-1036, 2016) meta-analysis and genetic sensitivity analyses were based on the 23andMe discovery dataset. Latent Growth Models suggested that polygenic risk score for major depression was associated with higher depressive symptoms across adolescence (significant main effect), particularly for those experiencing elevated levels of critical parenting (significant G × E). These findings highlight how polygenic risk for major depression in combination with a general environmental factor impacts depressive symptom development from early to late adolescence.

Social Withdrawal and Romantic Relationships: A Longitudinal Study in Early Adulthood.

Involvement in romantic relationships is a salient developmental task in late adolescence and early adulthood, and deviations from normative romantic development are linked to adverse outcomes. This study investigated to what extent social withdrawal contributed to deviations from normative romantic development, and vice versa, and the interplay between withdrawal and couples' relationship perceptions. The sample included 1710 young adults (55-61% female) from the Tracking Adolescents' Individual Lives Survey cohort and their romantic partners. Data were collected across 4 waves, covering romantic relationships from ages 17 to 29 years. The results showed that higher withdrawal predicted a higher likelihood of romantic non-involvement by adulthood, consistently being single at subsequent waves, and entering one's first relationship when older. Withdrawal moderately decreased when youth entered their first relationship. Male's withdrawal in particular affected romantic relationship qualities and dynamics. These results provide new insights into the developmental sequelae of withdrawn young adults' romantic relationship development.

Daily Identity Dynamics in Adolescence Shaping Identity in Emerging Adulthood: An 11-Year Longitudinal Study on Continuity in Development.

According to identity theory, short-term day-to-day identity exploration and commitment processes are the building blocks for long-term development of stable commitments in emerging adulthood. This key assumption was tested in a longitudinal study including 494 individuals (43% girls, Mage T1 = 13.31 years, range 11.01-14.86 years) who were followed from adolescence into emerging adulthood, covering ages 13 to 24 years. In the first five years, adolescents reported on their daily identity processes (i.e., commitment, reconsideration and in-depth exploration) across 75 assessment days. Subsequently, they reported on their identity across four (bi-) annual waves in emerging adulthood. Findings confirmed the existence of a dual-cycle process model of identity formation and identity maintenance that operated at the within-person level across days during adolescence. Moreover, individual differences in these short-term identity processes in adolescence predicted individual differences in identity development in emerging adulthood. Specifically, those adolescents with low daily commitment levels, and high levels of identity reconsideration were more likely to maintain weak identity commitments and high identity uncertainty in emerging adulthood. Also, those adolescents characterized by stronger daily changes in identity commitments and continuing day-to-day identity uncertainty maintained the highest identity uncertainty in emerging adulthood. These results support the view of continuity in identity development from short-term daily identity dynamics in adolescence to long-term identity development in emerging adulthood.

On Imbalance of Impulse Control and Sensation Seeking and Adolescent Risk: An Intra-individual Developmental Test of the Dual Systems and Maturational Imbalance Models.

Heterogeneity in development of imbalance between impulse control and sensation seeking has not been studied until now. The present study scrutinized this heterogeneity and the link between imbalance and adolescent risk. Seven-wave data of 7,558 youth (50.71% males; age range from 12/13 until 24/25) were used. Three developmental trajectories were identified. The first trajectory, "sensation seeking to balanced sensation seeking", included participants with a higher level of sensation seeking than impulse control across all ages. The second trajectory, "moderate dominant control", included participants showing moderate and increasing impulse control relative to sensation seeking across all ages. The third trajectory, "strong late dominant control", included participants showing the highest level of impulse control which was about as strong as sensation seeking from early to middle adolescence and became substantially stronger from late adolescence to early adulthood. Although the systematic increase of impulse control in all subgroups is in line with both models, neither of these combined trajectories of control and sensation seeking was predicted by the Dual Systems Model or the Maturational Imbalance Model. Consistent with both models the "sensation seeking to balanced sensation seeking" trajectory showed the highest level of substance use. It can be concluded that, even though both theories adequately predict the link between imbalance and risk, neither the Dual Systems Model nor the Maturational Imbalance Model correctly predict the heterogeneity in development of imbalance between impulse control and sensation seeking.

Diverse-and-Dynamic Pathways in Educational and Interpersonal Identity Formation during Adolescence: Longitudinal Links With Psychosocial Functioning.

This study aimed to examine the relations between educational and interpersonal identity trajectories and psychosocial functioning based on a three-factor identity process model. A total of 968 Japanese adolescents including 13- and 16-years-olds (49.7% female) participated in a four-wave longitudinal study. Latent class growth analysis extracted five identity trajectories in each educational and interpersonal identity domain and revealed (a) high prevalence of low commitment identity trajectories, (b) absence of the closure trajectory, and (c) changeable identity trajectories that have not been identified in Western context (i.e., the Netherlands). Furthermore, a latent change model revealed dynamic relations between identity trajectories and psychosocial functioning. These findings provide critical insights into the diverse and dynamic pathways of identity formation during adolescence in Japan.

Parental Age and Offspring Childhood Mental Health: A Multi-Cohort, Population-Based Investigation.

To examine the contributions of maternal and paternal age on offspring externalizing and internalizing problems, this study analyzed problem behaviors at age 10-12 years from four Dutch population-based cohorts (N = 32,892) by a multiple informant design. Bayesian evidence synthesis was used to combine results across cohorts with 50% of the data analyzed for discovery and 50% for confirmation. There was evidence of a robust negative linear relation between parental age and externalizing problems as reported by parents. In teacher-reports, this relation was largely explained by parental socio-economic status. Parental age had limited to no association with internalizing problems. Thus, in this large population-based study, either a beneficial or no effect of advanced parenthood on child problem behavior was observed.

The social withdrawal and social anxiety feedback loop and the role of peer victimization and acceptance in the pathways.

Social withdrawal and social anxiety are believed to have a bidirectional influence on one another, but it is unknown if their relationship is bidirectional, especially within person, and if peer experiences influence this relationship. We investigated temporal sequencing and the strength of effects between social withdrawal and social anxiety, and the roles of peer victimization and acceptance in the pathways. Participants were 2,772 adolescents from the population-based and clinically referred cohorts of the Tracking Adolescents' Individual Lives Survey. Self- and parent-reported withdrawal, and self-reported social anxiety, peer victimization, and perceived peer acceptance were assessed at 11, 13, and 16 years. Random-intercept cross-lagged panel models were used to investigate within-person associations between these variables. There was no feedback loop between withdrawal and social anxiety. Social withdrawal did not predict social anxiety at any age. Social anxiety at 11 years predicted increased self-reported withdrawal at 13 years. Negative peer experiences predicted increased self- and parent-reported withdrawal at 13 years and increased parent-reported withdrawal at 16 years. In turn, self-reported withdrawal at 13 years predicted negative peer experiences at 16 years. In conclusion, adolescents became more withdrawn when they became more socially anxious or experienced greater peer problems, and increasing withdrawal predicted greater victimization and lower acceptance.

Social comparison at school: Can GPA and personality mutually influence each other across time?

OBJECTIVE: Being a student is an important social role youth play during adolescence and how they approach this role has critical implications for their future development. This three-wave longitudinal study investigated the links between academic achievement (i.e., GPA) and personality traits, through the lens of social comparison mechanisms. METHOD: Patterns of effects between students' GPA and personality traits were analyzed at group (i.e., comparing rank-order differences at group-level; group effects) and individual (i.e., scores are compared to a student's own mean; within-person effects) levels. A total of 1,151 adolescents (Mage  = 16.45 years; 58.7% female) participated in the study. RESULTS: Most effects we depicted were from GPA to personality traits. At the group-level, higher GPA fostered students' Extraversion, Agreeableness, and Openness, while Openness reinforced high levels of GPA. At the individual level, GPA was a protective factor against negative affect, as it drove longitudinal decreases in Neuroticism. CONCLUSIONS: GPA had a stronger role in personality formation when it reflected students' standing in the school compared to their peers (i.e., group effects) and to a lesser extent when it reflected changes at personal level (i.e., within-person effects).

Parent-adolescent relationship quality as a predictor of leaving home.

INTRODUCTION: Leaving home is a significant life transition that effects both emerging adults and their families. The age of leaving home has been increasing across industrialized societies, and children remain dependent on their parents for a longer time. The present study investigated the association between parent-adolescent relationships and timing of leaving home over a timespan of six years: From middle adolescence to emerging adulthood. METHODS: Data came from three cohorts of two longitudinal studies in the Netherlands (N = 1100). At the start of the study, participants had a mean age of 16.41 (SD=.71), and approximately half of them (n = 547) were male. Adolescents completed questionnaires on parent-adolescent relationship quality. The impact of positive and negative relationship characteristics on timing of leaving home were examined separately for mothers and fathers. RESULTS: Survival analysis results showed that higher levels of mother's and father's warmth, and higher levels of power attributed to father, but not mother, predicted later timing of leaving home. Higher levels of parental autonomy support predicted earlier timing of leaving home. Conflict with parents was not associated with timing of leaving home, except in the father-daughter relationship. Only, the effect of parental warmth on timing of leaving home remained robust when controlling for age, gender, education level, and SES. CONCLUSIONS: Our findings indicate that certain parent-adolescent relationship characteristics contribute to the increase in age of leaving home. Parents may be able to prepare their children for a self-sufficient living by balancing warmth and autonomy support they provide during adolescence.
