Longitudinal associations between parents' prosocial behavior and media use and young children's prosocial development: The mediating role of children's media use.

Research has found that media is associated with children's prosocial behavior (PB) from an early age, and that parents play a key role in children's media use and behavior. However, few studies explore these relations as early as infancy while also controlling for well-established predictors of PB (e.g., empathic concern). Thus, the present study examined longitudinal associations between parents' PB and media use, and prosocial development during early childhood, mediated by children's own media use. Participants were 519 children (M age at Time 1 = 17.77 months) and parents who participated in three timepoints of an ongoing, longitudinal study. A longitudinal path model suggested that children's media use was still significantly associated with PB 1 year later after accounting for factors such as parents' PB, media use, and empathy. These findings have important implications for the early development of behaviors that serve as a foundation for social and moral development.

Latent Growth in Self-Regulatory Subdimensions in Relation to Adjustment Outcomes in Youth Aged 12-19.

This study assessed latent growth in behavioral inhibition, anger regulation, and goal-setting from ages 12 to 18, as well as links between latent growth and depression, externalizing behavior, and prosocial behavior at age 19. A second goal included examining whether latent growth in these constructs and associations with distal outcomes varied by sex. Generally speaking, self-regulatory subdimensions displayed distinct patterns of developmental growth from ages 12 to 18. Growth in self-regulatory subdimensions did not vary by sex, though initial levels of anger regulation and goal-setting did vary by sex. In addition, self-regulatory subdimensions from ages 12 to 18 were differentially related to adjustment outcomes at age 19. However, sex did not moderate associations between growth in self-regulatory subdimensions and distal outcomes.

Can helping others strengthen teens? Character strengths as mediators between prosocial behavior and adolescents' internalizing symptoms.

INTRODUCTION: Identifying protective factors against internalizing behaviors during adolescence is a public health priority, as rates of depression and anxiety are rising. As such, the purpose of this study was to examine whether prosocial engagement toward strangers and family members is protective against depressive and anxiety symptoms, and whether this link is mediated by character strengths (i.e., hope, persistence, gratitude, and self-esteem). METHOD: The sample consisted of 500 US adolescents (52% female; 66% European American; 33% from single-parent families). Data across three consecutive yearly waves were utilized in the current study (Mage Time 1 = 13.32). RESULTS: Results of a longitudinal structural equation model revealed prosocial behavior toward strangers and family members were differentially related to character strengths, and that prosocial behavior toward strangers was indirectly associated with depressive symptoms via self-esteem. CONCLUSION: Taken together, findings extend the Developmental Cascades model and suggest that prosocial behavior and character strengths protect against depressive symptoms during the adolescent period. Findings are discussed in the context of relevant research and theory, and implications for future research and intervention programs are presented.

Intra-individual associations between intentional self-regulation and prosocial behavior during adolescence: Evidence for bidirectionality.

INTRODUCTION: Couched in Positive Youth Development (PYD) theory and relevant empirical work, this study investigated bidirectional associations between intentional self-regulation and prosocial behavior toward strangers from age 12 to age 18. METHOD: Participants included 500 adolescents (52% female, 77% European American; age Time 1 = 12 years, Time 2 = 14 years, Time 3 = 16 years, Time 4 = 18 years) from the Northwestern United States. Adolescents self-reported on their intentional self-regulation and prosocial behavior toward strangers across four time points. A random-intercept cross-lagged panel model (RICLPM) was estimated in order to assess bidirectionality while avoiding conflating intra- and inter-individual variability. RESULTS: Results revealed intentional self-regulation and prosocial behavior toward strangers were bidirectionally related during early adolescence (i.e., from age 12 to 14). During mid-to-late adolescence (i.e. age 14 to 18), prosocial behavior toward strangers facilitated intentional selfregulation, whereas intentional self-regulation did not drive the development of prosocial behavior toward strangers. CONCLUSIONS: Findings indicate that early adolescence may be a particularly plastic developmental period in terms of PYD. Findings also suggest that investigations of relations between adolescents' personal assets and contribution factors merit further scholarly attention. Several directions for future research are presented.

Associations between prosocial behavior, externalizing behaviors, and internalizing symptoms during adolescence: A meta-analysis.

INTRODUCTION: The purpose of this study was to conduct a meta-analysis investigating the consistency and strength of relations between prosocial behavior, externalizing behaviors, and internalizing symptoms from preadolescence (i.e., 1-9 years) to late adolescence (i.e., 19-25 years). This study directly addresses inconsistencies and gaps in the available literature by providing the field with a detailed, synthesized description of these associations. METHOD: Fifty-five studies met the inclusion criteria, containing 742 independent correlational effect sizes. Statistical information and other study information was coded and entered into Comprehensive Meta-analysis III software, which was used to analyze results. RESULTS: Results showed that higher levels of prosocial behavior were significantly associated with lower levels of externalizing behaviors, as expected. Additionally, more reported prosocial behavior was related to less reported internalizing symptoms. Follow-up analyses revealed specific relationships between prosocial behavior and aggression, deviant peer association, risky sexual behavior, substance use, delinquency/general externalizing behavior, depression, and general internalizing behaviors (i.e., emotional problems, negative emotionality). A variety of moderators of these associations were considered, including age and sex. CONCLUSIONS: Findings are discussed in the context of the broader research literature, weaknesses in the field are noted, and numerous meaningful directions for future research are presented.

Parent-child joint media engagement in infancy.

Early conversations are an important source in shaping children's cognitive and emotional development, and it is vital to understand how parents use media as a platform to engage in conversations with their young children and what might predict the quality of these interactions. Thus, in the current study we explored the nature of parent-child discourse while engaging in media (i.e., joint media engagement) with infants, and how parent (empathic concern and responsiveness) and child (negative emotionality and regulatory capacity) variables might be associated with the quality of engagement. The current study consisted of 269 infants (50% female, Mage  = 17.09 months, SD = 3.93; 59% White) and their primary caregiver (98% mothers) who engaged in a variety of in-home tasks and parental questionnaires. Results established three meaningful codes for both parent and child that assessed positive and negative joint media engagement. Further, results suggested that parental empathic concern was associated with positive parent and child media engagement, while child negative emotionality was associated with lower levels of distraction. Discussion focuses on the importance of studying parent-child discourse in the context of joint media engagement and recommends limiting media exposure before 18 months of age.

Trajectories of Perceived Parental Psychological Control across Adolescence and Implications for the Development of Depressive and Anxiety Symptoms.

Theory and research indicate considerable changes in parental control across adolescence (e.g., declining behavioral control), but the developmental course and significance of psychological control remains largely unknown. This study examined trajectories of adolescents' reports of mothers' and fathers' psychological control from ages 12 to 19, predictors of occupying distinct trajectories, and the developmental significance of these trajectories for adolescents' development of depressive and anxiety symptoms. It used eight waves of survey data on 500 adolescents (Mage = 11.83, SD = 1.03; 52% female; 67% White, 12% African American) and their parents from the Pacific Northwest United States. Most adolescents (about 90%) reported low but increasing levels of parental psychological control over time, with a small but significant subset (about 10%) perceiving perpetually elevated levels. Mothers' (but not fathers') depressive symptoms, reported at the age 12 assessment, predicted adolescents' membership in the elevated psychological control trajectory. Adolescents occupying these elevated trajectories showed more problematic growth in depressive and anxiety symptoms across adolescence. Taken together, the findings suggest that many adolescents experience increased parental psychological control as they age, and that variability in these trends indicates individual differences in their development of depressive and anxiety symptoms over time.

Instagrowth: A Longitudinal Growth Mixture Model of Social Media Time Use Across Adolescence.

This study examined differential patterns of time spent using social media in a sample of 457 adolescents over a 6-year period. The majority of adolescents (83%), termed moderate users, reported steady social media use over time. A second group (increasers: 12%) reported low social media use that increased gradually and ended high at the end of the study. A third group, called peak users (6%), reported low social media that increased quickly after a few years and then returned to baseline levels. Low self-regulation predicted being an increaser or peak user. Being a moderate user tended to be related to lower levels of depression, aggression, delinquency, social media problems, and cyberbullying across time, as compared with the other groups.

Parental media monitoring, prosocial violent media exposure, and adolescents' prosocial and aggressive behaviors.

Prosocial violent media (e.g., media that combines both violent and prosocial content) is especially popular in entertainment media today. However, it remains unclear how parental media monitoring is associated with exposure to prosocial violent content and adolescent behavior. Accordingly, 1,193 adolescents were asked about parental media monitoring, media content exposure, and behavior. Main findings suggest that autonomy supportive restrictive monitoring was associated with lower levels of exposure to prosocial violent content, but only among older adolescents. Additionally, autonomy supportive restrictive monitoring was the only form of parental media monitoring associated with lower levels of violent content and higher levels of prosocial content, and autonomy supportive active monitoring was the only parental monitoring strategy that promoted prosocial behavior via exposure to prosocial media content. Discussion focuses on the importance of autonomy supportive parental monitoring, as well as the implications of parents encouraging their children to watch media with limited violent content-even if it is prosocial violent content.

A Six-Year Longitudinal Study of Texting Trajectories During Adolescence.

This study examined growth trajectories of texting (and other media) over a 6-year time period. Participants were 425 adolescents from Washington, USA (age 13 at Time 1, age 18 at Time 6; 48% male, 68% European American). Analyses suggested a curvilinear pattern for texting and social media use, with rates peaking during midadolescence. There was also considerable heterogeneity in trajectories of texting. A growth mixture model revealed four distinct classes of individuals: perpetuals (14%), decreasers (7%), moderates (68%), and increasers (11%). Higher levels of depression, being a male, and coming from a single-parent family predicted being a "perpetual" texter. Perpetuals had the most problematic outcomes compared to other classes, including higher depression, anxiety, aggression, and poor relationships with fathers.

Longitudinal Change in Adolescents' Prosocial Behavior Toward Strangers, Friends, and Family.

There is little understanding about how prosocial behavior toward different targets might change over time, and what might promote initial levels and age-related changes in prosocial behavior. Thus, this study examined longitudinal change in prosocial behavior toward strangers, friends, and family from early adolescence through the transition to adulthood. Participants included 500 adolescents from the United States (age 12 to age 20; 52% female, 65% European American). Latent growth curve models suggested that prosocial behavior toward strangers increased across early to mid-adolescence and then flattened out during the transition to adulthood, prosocial behavior toward friends increased steadily, and prosocial behavior toward family was relatively stable across adolescence and then increased. Predictors of initial levels and growth in prosocial behavior varied by target.

Dimensions of Short-Term and Long-Term Self-Regulation in Adolescence: Associations with Maternal and Paternal Parenting and Parent-Child Relationship Quality.

Relatively little is known about the degree to which subcomponents of self-regulation change during early to middle adolescence. This study considered familial predictors (maternal/paternal regulatory support, antagonistic parenting, and parent-child closeness) of rank-order change in behavioral, emotional and cognitive regulation and perseverance over one year. N = 452 adolescents ages 11-16 years and their parents completed questionnaires and parent-child discussion tasks (48.7% male; 69.6% white). Results indicated minimal direct effects of parenting, though maternal and paternal parenting and parent-child closeness exerted small effects that were moderated by prior levels of cognitive regulation and perseverance. Parents may contribute to the development of complex regulatory capacities that mature after foundational emotional and behavioral regulation competencies.

Associations between Prosocial and Problem Behavior from Early to Late Adolescence.

Though recent research has highlighted prosocial behavior as negatively associated with problem behavior during adolescence, we know little about how these variables might be associated longitudinally, whether there are bidirectional effects, and whether there might be different patterns of co-occurrence of behaviors for different individuals. Thus, the current study examined relations between prosocial and problem behaviors in three different ways in an attempt to better understand these associations. Participants included 500 adolescents recruited from a Northwestern state in the USA who took part in the study every year from age 12 to 18 (50% female, 67% European American). Growth curve analyses suggested that change in prosocial behavior was negatively associated with change in aggression and delinquency over time. A longitudinal panel model suggested that prosocial behavior and aggression were negatively associated bidirectionally, and that prosocial behavior was negatively associated with delinquency over time. Finally, mixture modeling conducted at ages 12, 15, and 18 revealed heterogeneity in the ways in which prosocial and problem behaviors co-occur. The discussion focuses on the complexity of interrelations between prosocial behavior and problem behavior across adolescence.

Longitudinal Change in High-Cost Prosocial Behaviors of Defending and Including during the Transition to Adulthood.

Despite high profile examples that are highlighted in the popular media, we know little about high-cost prosocial behaviors such as defending and including, and how these behaviors might change over time and vary by individual. Thus, this study explored defending and including behaviors across the transition to adulthood by assessing growth and profiles of these high-cost prosocial behaviors over a four-year time span. In addition the study explored gender, emotional (sympathy), cognitive (personal values), individual (self-esteem), and relational (maternal warmth) factors during adolescence that predicted profiles of defending and including during the transition to adulthood. Participants were 469 individuals (52% female, 70% European American) who participated at four time points (ages 18-21). Growth curve analyses showed that defending and including behaviors decreased slightly across the transition to adulthood and these behaviors tended to vary as a function of the target of the behavior. Latent profile analyses revealed three groups at each age, one with low, one with medium, and one with high levels of defending and including. The discussion focused on the prevalence and change in defending and including behaviors during the transition to adulthood, as well as the variability that exists in high-cost behavioral profiles.

The Protective Role of Parental Media Monitoring Style from Early to Late Adolescence.

The goal of the current study was to examine the protective role that maternal media monitoring might have for adolescents. This was done by considering whether styles of media monitoring either directly reduced media use, or whether they buffered the associations between aggressive media use and adolescents' prosocial behavior, aggression, and delinquency. Participants were 681 adolescents from two cities in the United States (51% female; 73% white), and their mothers, who provided data at two different time points, 2 years apart (when adolescents were roughly ages 13 and 15). Mixture modeling results revealed that mothers used four different styles of media monitoring made up of combinations of active and restrictive monitoring as well as forms of co-use. Styles that included active monitoring and connective co-use (i.e., engaging in media with the intent to connect with children) were directly associated with less media use, and moderated links between adolescents' media use and behavioral outcomes concurrently but not longitudinally. The discussion was focused on the strength of considering multiple strategies of media monitoring together, and how this approach can inform future research in the area of parental media monitoring.

How do men and women help? Validation of a multidimensional measure of prosocial behavior.

The current study sought to address gender differences in prosocial behavior by creating and validating a multidimensional measure of prosocial behavior that more fully captures the ways that men help others. The new measure is directed toward family, friend, and strangers, and has five factors: defending, emotional support, inclusion, physical helping, and sharing. In Study 1, CFA analyses performed on a sample of 463 emerging adults online (mean age 23.42) revealed good model fit and divergent validity for each of the five factors. Study 2 replicated the analyses on a sample of 453 urban adolescents in the Northwest (mean age 18.37). Results established that all factors had good model fit, construct validity, and convergent validity. The discussion focuses on implications of this measure for future prosocial research including an increased diversity in how people (particularly men) help others and developmental differences toward different targets of prosocial behavior.

Longitudinal relations between adolescents' self-esteem and prosocial behavior toward strangers, friends and family.

The present study examined age-trends and longitudinal bidirectional relations in self-esteem and prosocial behavior toward strangers, friends, and family over a four-year time period (age 11 to 14). A total of 681 adolescents were recruited in the United States (51% girls, 28% single parent families). A longitudinal panel model was conducted and the results showed that adolescent self-esteem was associated longitudinally with subsequent prosocial behavior toward strangers, and earlier prosocial behavior toward strangers promoted subsequent self-esteem. There were no such bidirectional relations between self-esteem and prosocial behavior toward friends and family. Findings also highlight the complexity of adolescent development of selfesteem and the multidimensional nature of prosocial behavior. Discussion focuses on understanding the dynamic interplay between adolescent selfesteem and prosocial behavior.

Longitudinal relations between parental media monitoring and adolescent aggression, prosocial behavior, and externalizing problems.

The current study examined longitudinal relations between parental media monitoring and adolescent behavior, and explored indirect effects via sympathy and self-regulation. A sample of adolescents and their mothers from Northwestern and Mountain West cities in the USA participated in a study at three time points, approximately one year apart (N = 681; M age of child at Time 3 = 13.33, SD = 1.06; 51% female; 73% European American, 9% African American, 17% Multi-ethnic). Though findings varied by reporter, results suggested that restrictive and active media monitoring were indirectly associated with adolescents' prosocial behavior, aggression, and externalizing behavior, with restrictive monitoring being somewhat maladaptive and active monitoring adaptive. The discussion focuses on the need to examine multiple aspects of media monitoring, and highlights implications of findings for parents.

Does Helping Keep Teens Protected? Longitudinal Bidirectional Relations Between Prosocial Behavior and Problem Behavior.

The current study examined bidirectional, longitudinal links between prosocial and problem behavior. Participants (N = 500) were recruited from a Northwestern city in the United States and assessed for 3 consecutive years from 2009 to 2011 (M(age) of youth at Time 1 = 13.32, SD = 1.05; 52% girls; 67% European American, 33% single-parent families). Results suggested that effects of earlier prosocial behavior toward family and strangers were predictive of fewer problem behaviors 2 years later, while results for prosocial behavior toward friends were more mixed. Results also suggested depression predicted lower prosocial behavior toward family members and anxiety predicted higher prosocial behavior toward friends. Findings show a complex pattern of relations that demonstrate the need to consider targets of helping.

Brief report: Danish emerging adults' conceptions of adulthood.

Four hundred Danish emerging adults ages 17-29 were surveyed regarding their conceptions of adulthood and their self-assessments of their adult status. A majority of the 17-24-year-olds and nearly half the 25-29-year-olds viewed themselves as being adults in some ways but not others. Participants reported feeling most adult when with co-workers or romantic partners, and least adult with mothers, fathers, or friends. The most widely-endorsed criteria for adulthood were accepting responsibility for one's self, making independent decisions, and becoming financially independent. Among the least-endorsed criteria were the traditional transition events of entering marriage and parenthood, as well as "avoid becoming drunk."
