Capturing the interplay among within- and between-person processes using multilevel modeling techniques

The Interplay Between Personal Identity and Social Identity Among Vocational High School Students: A Three-Wave Longitudinal Study

Although identity research has predominantly focused on college-bound adolescents, it has largely neglected vocational high school students who enter the job market immediately after graduation. Furthermore, most studies have concentrated on personal identity and have overlooked the concurrent development of social identity. This study examined the relationship between adolescents' personal and social identities over three years of vocational high school. The participants were 4,264 vocational high school students in Japan (Time 1: 46.44% girls; Mage = 15.78). Using a random intercept cross-lagged panel model, the results indicated that within-person increases in social identity predicted increases in personal identity one year later. These findings highlight the importance of social identity as a valuable resource for personal identity development among vocational high school students, a group underrepresented in identity research.

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.

Does willingness to care fluctuate over time? A weekly diary study among informal caregivers

OBJECTIVE

Informal caregivers are expected to be willing to care for relatives with care needs. Little is known about whether and how willingness to care changes over time. Using a weekly diary study, we examined changes in the willingness of 955 caregivers from nine countries. Caregivers provided information on their caregiving context, relationship type, and relationship satisfaction with the care recipient.

METHODS AND MEASURES

For 24 consecutive weeks, caregivers evaluated willingness to care as it was 'right now'.

RESULTS

Willingness differs from one caregiver to another (68% between-level variability) but also fluctuates in the same caregiver from week to week (32% within-level variability), with a decrease over 6 months (intercept = 8.55; slope = -0.93; p < .001). Regardless of individual differences in average willingness to care based on caregiving context and relationship satisfaction, caregivers reported decreases in willingness. Caregivers who presented one or more health conditions themselves reported higher weekly fluctuations in willingness than caregivers with no health conditions.

CONCLUSION

Willingness is not a stable attitude because it decreases and caregivers experience fluctuations from week to week. A clearer understanding of weekly processes is optimal for monitoring the caregivers' well-being and tailoring interventions in line with weekly individual variations.

Meeting in school: Cultural diversity approaches of teachers and intergroup contact among ethnic minority and majority adolescents

This study investigated the associations between cultural diversity approaches endorsed by teachers and adolescents' positive and negative intergroup contact in schools. Participants were 984 adolescents (M_age  = 14.66; 62.7% female; 24.8% ethnic minority) involved in a three-wave longitudinal study between 2019 and 2020. Results highlighted that perceived equal treatment by teachers was related to higher positive and lower negative contact over time. However, perceived support for contact and cooperation and interest of teachers in children's cultural background were not related to either positive or negative contact over time. Importantly, the results were replicated across ethnic minority and majority adolescents. This study provides novel insights into the key role that teachers can play in promoting cultural diversity approaches to facilitate harmonious intergroup interactions in schools.

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, M_age  = 13.02, SD = 0.44, at T1; M_age  = 17.02, SD = 0.44, at T5), their mothers (N = 419, M_age  = 44.48, SD = 4.17, at T1), and their fathers (N = 419, M_age  = 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.

Transactional Links Between Social Anxiety Symptoms and Parenting Across Adolescence: Between- and Within-Person Associations

This 4-year longitudinal multi-informant study examined between- and within-person associations between adolescent social anxiety symptoms and parenting (parental psychological control and autonomy support). A community sample of 819 adolescents (46.1% girls; Mage T1  = 13.4 years) reported annually on social anxiety symptoms and both adolescents and mothers reported on parenting. Between-person associations suggested that adolescent social anxiety symptoms were associated with higher adolescent- and mother-reported psychological control and lower mother-reported autonomy support. At the within-person level, however, mothers reported lower psychological control and higher autonomy support after periods with higher adolescent social anxiety symptoms. Our findings illustrate the importance of distinguishing among between-person and within-person associations and including perceptions of both dyad members in longitudinal research concerning parenting and adolescent mental health.

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 (M_age  = 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).

Prejudice and Inclusiveness in Adolescence: The Role of Social Dominance Orientation and Multiple Categorization

This study examined the relations of multiple categorization and social dominance orientation with adolescents' prejudice against migrants and identification with the human group over time. Participants were 304 Northern-Italian late adolescents (61.84% female, M_age  = 17.49) involved in a three-wave longitudinal study (with 3 months interval between waves). Results showed that multiple categorization was negatively linked to prejudice at a later time, whereas social dominance orientation was positively associated with it; prejudice also negatively affected multiple categorization and positively affected social dominance orientation at a later time. Moreover, prejudice mediated the effects of multiple categorization and social dominance orientation on human identification. These findings have important implications suggesting the construens effect of multiple categorization for enhancing social inclusiveness.

Identity Structure and Processes in Adolescence: Examining the Directionality of Between- and Within-Person Associations

Developing a stable and coherent identity structure (i.e., a synthesized sense of self that can support self-directed decision making) represents a lifelong task. A person's identity structure is continually revised through ongoing processes of identity exploration and commitment. However, longitudinal studies linking identity structure to identity processes are largely lacking. The present three-wave longitudinal study among 530 Flemish high school students [50.6% female; M_age = 15; SD = 1.85; age range = 11-19 years] examined the directionality of both between- and within-person associations linking identity synthesis and confusion to identity exploration and commitment processes. Between-person cross-lagged models indicated that adolescents who scored high on identity synthesis relative to their peers also scored high on proactive exploration and commitment processes, and low on ruminative exploration one year later, again relative to their peers. Adolescents who scored high on identity confusion relative to their peers also scored high on ruminative exploration one year later, again relative to their peers. With respect to effects of identity processes on identity structure, adolescents who scored high on identification with commitment relative to their peers also scored low on identity confusion one year later. Within-person cross-lagged models indicated that, when adolescents scored high on identity synthesis relative to their own average score, they reported increased proactive exploration processes one year later. In general, reaching a degree of identity synthesis appears to represent a prerequisite for proactive identity exploration at both the between- and within-person levels.

Reduced frontal grey matter, life history of aggression, and underlying genetic influence

Physically healthy, adult, same-sexed twins (n = 287) from a population-based twin cohort underwent high-resolution magnetic resonance imaging (MRI) to identify fronto-limbic brain regions significantly associated with lifetime history of aggression. MRI scans used a 3D magnetization-prepared rapid acquisition gradient-echo (MP-RAGE) sequence, for voxel-based morphometry (VBM) and history of aggressive behavior was assessed using the Life History of Aggression measure. Aggression had modest, inverse associations with grey matter volume (GMV) in medial prefrontal cortex (mPFC, b = -0.20, se = 0.05, p < 0.001) and lateral prefrontal cortex (lPFC, b = -0.23, se = 0.06, p < 0.001). These associations were not confounded by other demographic, psychiatric, or personality factors. Biometrical twin analyses revealed significant heritabilities of 0.57 for GMV in the mPFC cluster and 0.36 for GMV in the lPFC cluster. Genetic factors accounted for the majority of the phenotypic correlations between aggression and mPFC GMV (85.3%) and between aggression and lPFC GMV (63.7%). Reduced GMV of prefrontal brain regions may be a neuronal characteristic of individuals with substantial histories of aggressive behavior regardless of psychiatric diagnosis. As such, these data suggest an anatomical correlate, with a possible genetic etiology, associated with functional deficits in social-emotional information processing.

Clear Self, Better Relationships: Adolescents' Self-Concept Clarity and Relationship Quality With Parents and Peers Across 5 Years

This study examined reciprocal associations between adolescents' self-concept clarity (SCC) and their relationship quality with parents and best friends in a five-wave longitudinal study from age 13 to 18 years. In all, 497 adolescents (57% boys) reported on their SCC and all informants (i.e., adolescents, both parents, and adolescents' best friends) reported on support and negative interaction. Within-person cross-lagged analyses provided systematic evidence for both parent effects and child effects, with the direction of effects being strongly dependent on the relational context. For example, higher maternal support predicted higher adolescent SCC, supporting a parent effects perspective, whereas higher SCC predicted lower paternal negative interaction, supporting a child effects perspective. Peer effects on adolescent SCC were not consistently found across adolescent and best friend reports.

Predicting young adults' risk for engaging in prescription drug misuse in daily life from individual, partner, and relationship factors

BACKGROUND

Mounting evidence based on retrospective and global assessments has established associations between prescription drug misuse and illicit drug use, alcohol abuse, mental health problems, risky sexual behaviors, and overdose deaths. However, there is a notable absence of identified risk and protective factors for an individual's likelihood of engaging in misuse in real-world environments.

METHODS

Using an experience sampling approach, the authors collected repeated moments of young adults' (n = 95 participants drawn from 49 romantic couples) prescription drug misuse instances in daily life and tested multiple factors associated with the misuse.

RESULTS

When examined in separate multilevel models, individual and relationship factors (but not partner factors) reliably predicted the likelihood of females' and males' prescription drug misuse in daily life. Specifically, females' elevated dysphoria symptoms, alcohol problems, and relationship closeness were linked with an increased likelihood of misuse, whereas cohabiting decreased the likelihood of their misuse. Males' higher levels of illicit drug use and relationship closeness were associated with increased likelihood of misuse, whereas their dysphoria symptoms were related to a lower likelihood of misuse. When examined in models that considered the predictors simultaneously, females' misuse was associated with individual, partner, and relationship factors, whereas males' misuse was not reliably associated with any of the factors.

CONCLUSIONS

An experience sampling approach was effective for the near-real-time assessment of young adults' prescription drug misuse in daily environments, and the likelihood of misuse was associated with risk and protective factors from multiple levels of influence. Education and treatment efforts designed to reduce prescription drug misuse may need to be tailored to accommodate males' and females' distinct predictors of misuse.

Momentary affect and risky behavior correlates of prescription drug misuse among young adult dating couples: An experience sampling study

Although published research based on retrospective survey designs has established prescription drug misuse as a serious health issue for individuals and society, misuse behavior has not been investigated as it occurs in daily life and important relationships. To address this gap, young adult romantic couples were recruited from the community to participate in an experience sampling study. Participants were identified through phone screen procedures as having engaged in recent prescription drug misuse behavior. Participants (n=46 couples) completed electronic diary reports throughout the day for 10days, tapping momentary affect, sexual experiences, prescription drug misuse, and alcohol and other drug use. Dyadic multilevel modeling revealed a more consistent pattern of associations between prescription drug misuse and problematic affective and behavioral outcomes for female partners than male partners. Specifically, during epochs of females' prescription drug misuse, they experienced relatively higher levels of negative affect and sexual regret. Also, females who misused prescriptions more during the study period evidenced lower levels of sexual enjoyment and engaged in more unprotected sex, alcohol use, and heavy alcohol use in daily life. Males' in-the-moment prescription drug misuse was not associated with their concurrent outcomes, though males with relatively more misuse across the reporting period were more likely to engage in heavy drinking. Couples' time together emerged as a moderator of prescription drug misuse in daily life: Females who spent relatively more time with their partner across the study were less likely to engage in misuse, and proportion of time spent together moderated several of the momentary misuse-outcome linkages. This study supports the use of ecologically-valid sampling methods for characterizing young adults' prescription drug misuse in daily life and relationship contexts.

The longitudinal role of breastfeeding in mothers' and fathers' relationship quality trajectories

BACKGROUND

Guided by a family systems perspective, this study investigated whether breastfeeding plays a role in the quality of the mother-father intimate relationship over the course of child development.

METHODS

Using a prospective, longitudinal design, and data drawn from the National Institute of Child Health and Human Development Study of Early Child Care and Youth Development (n=986 couples), the present study examined the predictive role of breastfeeding in the first 3 years of life (for up to 4 months and for 5 months or longer, relative to never breastfeeding) in maternal and paternal trajectories of intimate relationship quality. The outcome variable of interest was emotional intimacy, rated by mothers and fathers when children were 54 months of age, in grades 1, 3, 5, and 6, and 15 years of age.

RESULTS

Multivariate hierarchical linear modeling, which appropriately handled dyadic data and accounted for effects of demographic covariates and earlier relationship quality, indicated that breastfeeding uniquely predicted increases in mothers' (but not fathers') marital quality levels over time. There was no difference in the strength of the positive associations for shorter versus longer breastfeeding duration. The findings suggest that improved intimate relationship quality may be another psychosocial benefit experienced by breastfeeding mothers.

CONCLUSION

The findings underscore the importance of considering breastfeeding in the context of intimate relationships and may be of interest to women weighing the decision to breastfeed, their partners, and healthcare providers.

Moderating effects of childhood maltreatment on associations between social information processing and adult aggression

BACKGROUND

Associations between early life maltreatment, social information processing (SIP) and aggression in childhood and adolescence have been widely documented. Few studies have examined the importance of childhood maltreatment independent of SIP in the etiology of adult aggression. Furthermore, moderating effects of childhood maltreatment on the SIP-aggression links have not been explored.

METHOD

Hierarchical, multi-level models were fitted to data from n=2752 twins aged 20-55 years from the PennTwins Cohort. Adult aggression was assessed with the Life History of Aggression questionnaire. Childhood maltreatment was measured using the Childhood Trauma Questionnaire. Two aspects of SIP were examined: hostile attribution biases (HAB); negative emotional responses (NER).

RESULTS

Childhood maltreatment was positively correlated with adult aggression, independently of HAB and NER. In addition, childhood maltreatment moderated the relationships between both aspects of SIP and adult aggression. Specifically, the relationship between NER and aggression was stronger among individuals with higher levels of childhood maltreatment and NER was not associated with aggression for adults who experienced low levels of childhood maltreatment. Moderating effects of childhood maltreatment on the NER-aggression link were supported for total childhood maltreatment, emotional neglect and emotional abuse. In contrast, HAB was more strongly associated with adult aggression at lower levels of emotional abuse and physical neglect.

CONCLUSIONS

The current study provides insight into the mechanisms by which early life experiences influence adult aggression. Our findings suggest that childhood maltreatment may not only lead to increased levels of aggression in adulthood but may also modify the associations between SIP and adult aggression.

Longitudinal Associations between Parental and Children's Depressive Symptoms in the Context of Interparental Relationship Functioning

Using longitudinal, multi-informant data from the National Institute of Child Health and Human Development Study of Early Child Care and Youth Development, the present study tested associations between trajectories of parental and child depressive symptoms from ages 11 to 15 years. Consistent with predictions, changes in mothers' and fathers' depressive symptoms were positively associated with change in children's depressive symptoms over time. In addition, youth characteristics of sex and pubertal development moderated the trajectories, with children more advanced on pubertal development showing higher initial levels of depressive symptoms, and girls demonstrating steeper slopes of depressive symptoms over time. The context of interparental relationship functioning (i.e., marital conflict, marital conflict resolution) moderated both the trajectories of child depressive symptoms and the interplay between parental and child depressive symptoms in ways largely consistent with hypotheses. Implications of the findings are discussed in terms of treating youth depressive symptoms with a consideration of the broader family context, including parental and interparental functioning.

Hostile attributional bias, negative emotional responding, and aggression in adults: moderating effects of gender and impulsivity

The current study examined the main effects of hostile attributional bias (HAB) and negative emotional responding on a variety of aggressive behaviors in adults, including general aggression, physical aggression, relational aggression, and verbal aggression. Effects of both externalizing (anger) and internalizing (embarrassment/upset) negative emotions were considered. In addition, the moderating roles of gender and impulsivity on the effects of HAB and negative emotional responding were explored. Multilevel models were fitted to data from 2,749 adult twins aged 20-55 from the PennTwins cohort. HAB was positively associated with all four forms of aggression. There was also a significant interaction between impulsivity and HAB for general aggression. Specifically, the relationship between HAB and general aggression was only significant for individuals with average or above-average levels of impulsivity. Negative emotional responding was also found to predict all measures of aggression, although in different ways. Anger was positively associated with all forms of aggression, whereas embarrassment/upset predicted decreased levels of general, physical, and verbal aggression but increased levels of relational aggression. The associations between negative emotional responding and aggression were generally stronger for males than females. The current study provides evidence for the utility of HAB and negative emotional responding as predictors of adult aggression and further suggests that gender and impulsivity may moderate their links with aggression.

Child psychopathic traits moderate relationships between parental affect and child aggression

OBJECTIVE

Previous studies show that children with psychopathic traits may be less responsive to parenting. Although harsh/inconsistent parenting is associated with increased problem behaviors in children low on psychopathic traits, children high on psychopathic traits show consistently high levels of problem behavior regardless of negative parenting. Moderating effects of child psychopathic traits on positive dimensions of parenting have not been explored.

METHOD

We applied multi-level regression models to test for interactions between child psychopathic traits and both positive and negative parental affect on individual differences in both reactive and proactive aggression, in a community-based sample of 1,158 children aged 9 through 10 years of age.

RESULTS

There were significant associations between child psychopathic traits and positive and negative parental affect with both forms of aggression. Child psychopathic traits also moderated effects of positive and negative parental affect. Children low on psychopathic traits showed decreasing reactive aggression as positive parental affect increased, and increasing levels of reactive aggression as negative parental affect increased, but children high on psychopathic traits showed more stable levels of reactive aggression regardless of levels of parental affect. Proactive aggression was more strongly associated with negative parental affect among children with higher levels of psychopathic traits.

CONCLUSIONS

In a community sample of preadolescent children, child psychopathic traits were shown to moderate the effects of parental affect on aggression. Reactive aggression in children high on psychopathic traits appears less responsive to variations in either positive or negative parenting. In contrast, child psychopathic traits may exacerbate the effects of high levels of negative parental effect on proactive aggression.

The course and quality of intimate relationships among psychologically distressed mothers

The longitudinal course and quality of intimate relationships were tested in relation to maternal depressive symptoms in a sample of 1,275 families from the National Institute of Child Health and Human Development Study of Early Child Care and Youth Development. Assessments of mothers' intimate relationship status, intimate relationship quality, and depressive symptoms were obtained on 11 occasions from the birth of a child through age 15. Consistent with predictions, results from hierarchical linear models indicated that maternal depressive symptoms over time were associated with a lower probability of being married and lower levels of relationship quality. The strength of the association between relationship quality and depression was stronger than the linkage between relationship course and depression. Sociodemographic characteristics (e.g., mother age, child gender, ethnicity) were more predictive of trajectories of relationship course than relationship quality. Findings are discussed in terms of efforts to prevent and treat the longitudinal interplay between poor intimate relationship functioning and partners' psychopathology and its implications for the overall health and well-being of parents, couples, and children.

Marital Aggression and Children's Responses to Everyday Interparental Conflict

This study examined parents' past marital aggression as a (1) predictor of everyday marital conflict expressions, and (2) moderator of children's responses to marital conflict. In a laboratory setting, children watched their parents discuss an everyday topic of disagreement and then reported their own emotional and behavioral reactions, and rated their parents' conflict resolution. Controlling for current marital aggression, couples with higher levels of past marital aggression used less constructive and more destructive conflict tactics, and displayed less positive and more negative emotions. Children's responses to marital conflict were moderated by parents' past marital aggression: Children whose parents had been more maritally aggressive in the past were more sensitive to parents' use of constructive conflict tactics and positive emotions. Thus, controlling for current marital aggression, past interparental aggression had implications for both parents' everyday interparental conflict and children's responding to everyday marital conflict.
