Polygenic Influences on Pubertal Timing and Tempo and Depressive Symptoms in Boys and Girls

This study used polygenic scoring (PGS) to test whether puberty‐related genes were correlated with depressive symptoms, and whether there were indirect effects through pubertal maturation. The sample included 8,795 adolescents from the Avon Longitudinal Study of Parents and Children (measures of puberty drawn ages 8–17 years; of depressive symptoms at age 16.5 years). The PGS (derived from a genome‐wide meta‐analysis of later age at menarche) predicted boys’ and girls’ later pubertal timing, boys’ slower gonadal development, and girls’ faster breast development. Earlier perceived breast development timing predicted more depressive symptoms in girls. Findings support shared genetic underpinnings for boys’ and girls' puberty, contributing to multiple pubertal phenotypes with differences in how these genetic variants affect boys' and girls' development.     

Linking Childhood Maltreatment With Girls' Internalizing Symptoms: Early Puberty as a Tipping Point

Earlier physical maturation may often be preceded by a range of adversities and life stressors. This study investigates childhood maltreatment, internalizing symptoms, and pubertal timing in girls residing in foster care (N = 100, M = 11.54 years old at Time 1). Girls were assessed at two time points 2 years apart. There were no direct effects of maltreatment on internalizing symptoms; rather, childhood sexual abuse predicted earlier pubertal development which, in turn, was associated with higher levels of internalizing symptoms concurrently and longitudinally. This distinctive role for early pubertal timing suggests that the heightened sexual circumstances of puberty may be especially disturbing for girls whose lives have already been disrupted by inappropriate and unwanted sexual experiences.     

Infant Sex Moderates the Effects of Maternal Pre‐ and Postnatal Stress on Executive Functioning at 8 Months of Age

Previous studies report that early life stress, including maternal pre‐ and postnatal stress, has adverse effects on cognitive development and that these associations might be sex‐specific. However, no studies exist on early life stress and infant executive functioning (EF). The aim of this study was to examine the relationship between maternal pre‐ and postnatal stress and infant EF, and whether these associations are moderated by infant sex. Maternal prenatal depressive, general anxiety, and pregnancy‐specific anxiety symptoms were measured three times, and postnatal depressive and general anxiety symptoms were measured 6 months postpartum. Infant EF was assessed with a modified A‐not‐B task 8 months postpartum (N = 214). Maternal postnatal general anxiety predicted poorer EF in girls in comparison with boys. Moreover, there was a trend toward an interaction between prenatal anxiety and infant sex such that prenatal anxiety predicted infant EF differently in girls and in boys. No association was found between depressive symptoms or pregnancy‐specific anxiety symptoms and infant EF. These findings suggest that maternal anxiety may have sex‐specific effects on early EF and that pre‐ and postnatal stress may differently affect infant EF/cognitive development. The implications of these findings and important future directions are discussed.     

Pubertal Timing as a Potential Mediator of Adoption Effects on Problem Behaviors

Adopted children show more problem behaviors than nonadopted children. Given that internationally adopted individuals show earlier puberty than nonadopted individuals, and early puberty is associated with problem behaviors in nonadopted youth, we analyzed data from adopted domestic adoptees to determine whether problem behaviors could be explained by differences in pubertal timing. Relative to nonadopted controls (n = 153), domestically adopted girls (n = 121) had earlier menarche, earlier sexual initiation, and more conduct disorder symptoms. Age at menarche partially mediated the relation of adoptive status to sexual initiation, but not to conduct disorder symptoms. Extending findings from international adoptees, results show that domestic adoption is also linked to earlier puberty, and suggest early puberty as one mechanism linking adoption to problematic outcomes.     

Infant Behavior and Competence Following Prenatal Exposure to a Natural Disaster: The QF2011 Queensland Flood Study

This study utilized a natural disaster to investigate the effects of prenatal maternal stress (PNMS) arising from exposure to a severe flood on maternally reported infant social–emotional and behavioral outcomes at 16 months, along with potential moderation by infant sex and gestational timing of flood exposure. Women pregnant during the Queensland floods in January 2011 completed measures of flood‐related objective hardship and posttraumatic stress (PTS). At 16 months postpartum, mothers completed measures describing depressive symptoms and infant social–emotional and behavioral problems (n = 123) and competence (n = 125). Greater maternal PTS symptoms were associated with reduced infant competence. A sex difference in infant behavioral problems emerged at higher levels of maternal objective hardship and PTS; boys had significantly more behavioral problems than girls. Additionally, greater PTS was associated with more behavioral problems in boys; however, this effect was attenuated by adjustment for maternal depressive symptoms. No main effects or interactions with gestational timing were found. Findings highlight specificity in the relationships between PNMS components and infant outcomes and demonstrate that the effects of PNMS exposure on behavior may be evident as early as infancy. Implications for the support of families exposed to a natural disaster during pregnancy are discussed.     

Early Childhood Maltreatment and Pubertal Development: Replication in a Population‐Based Sample

Early experiences are critically important for female reproductive development. Although a number of early childhood hardships predict earlier physical development in girls, research on specific populations suggests a distinct effect of childhood sexual abuse compared to other adversities. This study leverages the National Longitudinal Study of Adolescent Health (N = 6,273 girls) to test the generalizability of these findings, examining associations of early physical abuse, sexual abuse, and physical neglect with pubertal timing. Child sexual abuse predicted earlier menarche and development of secondary sexual characteristics, whereas other types of maltreatment did not. In addition to replicating results from smaller, more specialized samples, these findings reinforce the value of considering puberty within a broader “life span” continuum of birth to adolescence.     

“We're Supposed to Look Like Girls,But Act Like Boys”: Adolescent Girls’ Adherence to Masculinity Norms

In the ecological systems perspective, gender ideologies are part of the macrosystem that shapes human development. A growing literature indicates that youth accommodate and resist such ideologies, with adherence to masculinity norms being linked with negative adjustment. Most masculinity research focuses on boys’ adherence to masculinity, but girls are also pressured to uphold masculinity norms. Using mixed modeling, we examined girls’ adherence to masculinity and psychological (self‐esteem, depressive symptoms) and social (peer support and conflict) well‐being in the United States (N = 407; M_age = 12.28) and China (N = 356; M_age = 12.41). In both countries, adherence to masculinity was negatively associated with psychosocial well‐being. Chinese girls reported greater masculinity adherence, but associations with psychosocial well‐being were not moderated by nationality.     

Self‐Competence and Depressive Symptoms in Middle–Late Adolescence: Disentangling the Direction of Effect

This study examined the temporal relation between self‐competence (academic, social, athletic, physical appearance, and close friend) and depressive symptoms in a large, diverse community sample of 636 adolescents. Surveys were administered to all 10th‐ and 11th‐grade students at participating high schools at baseline (mean age = 16.10, SD = .71) and 1 year later. Girls reported higher levels of self‐competence in close friendships and more depressive symptoms, whereas boys reported higher levels of self‐competence in athletics and physical appearance. However, there were no gender differences in the associations between self‐competence and depressive symptoms. Results from autoregressive, cross‐lagged path analyses indicated that depressive symptoms predicted self‐competence more consistently than self‐competence predicted depressive symptoms during middle–late adolescence. Implications for prevention are discussed.     

A Twin Study of Objective and Subjective Pubertal Timing and Peer Influence on Risk‐Taking

This study used a behavioral genetic design to test whether three measures of pubertal timing moderated peer influence on risk‐taking in a sample of 248 female adolescent twin pairs (M_age = 16.0, SD = 1.5) from the National Longitudinal Study of Adolescent Health. Peer influence was operationalized as the quasi‐causal association between girls' self‐reported risk‐taking and the risk‐taking reported by their friends. Girls with earlier ages at menarche and who perceived themselves as more developed than peers were more susceptible to peer influence on risk‐taking. However, age‐standardized ratings of body changes did not moderate peer influence. This study highlights distinctions between multiple measures of pubertal timing, using an innovative synthesis of genetically informative data and peer nomination data.     

Self‐Perceived Competence in Mainland China: A Multiwave Longitudinal Examination of Internalizing Symptoms in Chinese Adolescents

The present 9‐wave, 2‐year study examined whether Cole's (1991) theory of self‐perceived competence could help explain vulnerability to depressive and anxiety symptoms in a sample of adolescents from mainland China. Participants included 624 adolescents (319 females and 305 males) from an urban school in Changsha (n = 308) and from a rural school in Liuyang (n = 316). Findings showed that self‐perceived academic competence was negatively associated with prospective depressive and anxiety symptoms. Meanwhile, adolescents with low levels of self‐perceived social competence were at heightened risk for depressive symptoms during times of increased stressors (supporting a vulnerability‐stress model). These findings advance past research by highlighting new developmental pathways for depressive and anxiety symptoms in Chinese adolescents.     

Adolescent Athletic Participation Patterns and Self‐Perceived Competence: Associations With Later Participation,Depressive Symptoms,and Health

Physical activity is important for well‐being across the life span. However, links between patterns of adolescent activity, competence perceptions, and young adult outcomes are underexplored. We used data from seven waves of the 4‐H Study of Positive Youth Development (N = 5,961) to assess patterns of adolescent athletic participation, whether these patterns were associated with self‐perceived athletic competence and young adult physical activity, depressive symptoms, and health, and associations between changes in participation across adolescence and young adult outcomes. Competence perceptions were associated with increased participation, and more active adolescents had higher rates of adult athletic activity, with links to better health and fewer depressive symptoms. We discuss results in light of the importance of using person‐centered analyses to understand active lifestyles.     

Maternal Regulation of Daughters' Emotion During Conflicts From Early to Mid‐Adolescence

Primary caregivers play an important role in emotion socialization. Real‐time mother–daughter emotion socialization was examined in 45 mother–daughter dyads with early‐adolescent daughters (age M = 11.80, SD = .27) at the first observation point. Maternal supportive emotion regulation and daughters' emotions were coded during two conflict discussions, 2 years apart. With multilevel survival analysis, the likelihood of maternal supportiveness was predicted both over time, between early and mid‐adolescence, and by daughters' pubertal status. Mothers were more likely to respond to daughters' negative and positive emotions with supportiveness for daughters whose pubertal maturation occurred relatively early. Results suggest that mothers adjust their socialization of daughters' emotions according to their daughters' pubertal development.     

Sexually Explicit Websites and Sexual Initiation: Reciprocal Relationships and the Moderating Role of Pubertal Status

A two‐wave panel study was conducted among adolescents (Mean age = 14.78; N = 639) to examine the relationship between using sexually explicit websites and sexual initiation with particular attention to adolescents' pubertal status. Structural equation modeling and logistic regression analysis indicated that frequent users of sexually explicit websites were five times more likely to initiate sexual intercourse than nonusers. Pubertal status moderated this relationship: an increased likelihood to initiate sex was found among adolescents in an early pubertal stage who frequently viewed sexually explicit websites. However, a lower likelihood to initiate sex was found among adolescents in an advanced pubertal stage. The possibility of a reciprocal relationship was also examined but was not supported.     

Spanish Validation of the Emotion Regulation Questionnaire for Children and Adolescents (ERQ‐CA): Introducing the ERQ‐SpA

Research on emotion regulation is now extensive and shows the benefits of the adaptive management of emotions for social functioning and psychological well‐being. Our purpose was to test the psychometric properties of the Emotion Regulation Questionnaire for Children and Adolescents with a sample of nonclinical Spanish adolescents. A total of 462 secondary education students (223 girls, mean age = 13.89 years, SD = 1.38) participated. The instrument proved to be two‐factor and gender‐invariant. Results revealed the temporal stability of both emotion regulation strategies, while the predictive validity study revealed that depressive symptoms were negatively related to cognitive reappraisal, and positively related to expressive suppression. Our findings support the use of the ERQ‐SpA in Spanish adolescents.     

Experiences With Parents and Youth Physical Health Symptoms and Cortisol: A Daily Diary Investigation

Using daily diary data, this study examined the associations between positive and negative parent–youth experiences and youth cortisol and physical health symptoms among a sample of adolescents (N = 132, mean age = 13.39). On days when girls reported more negative experiences than usual, they exhibited more physical health symptoms and flatter evening cortisol slopes than usual. Negative experiences with mothers were associated with higher dinner and bedtime youth cortisol levels (between‐person). Daily positive experiences with fathers were linked with lower dinner cortisol levels. Youth with high levels of negative experiences, on average, were less sensitive to daily variation in negative experiences than youth who experienced lower parental negativity. We discuss the benefits of a daily diary approach.     

The Moderating Effects of Pubertal Timing on the Longitudinal Associations Between Parent–Child Relationship Quality and Adolescent Substance Use

This prospective, longitudinal study investigated the moderating role of pubertal timing on reciprocal links between adolescent appraisals of parent–child relationship quality and girls' (N=1,335) and boys' (N=1,203) cigarette and alcohol use across a 12‐month period. Reciprocal effects were found between parent–child relations and on‐time maturing boys and girls' cigarette and alcohol use, after estimating stability in these constructs across time. Parent–child relationship quality was associated with increased alcohol use 12 months later for early maturing girls. Cigarette and alcohol use were associated with increased problems in the parent–child relationship for late maturing girls. No effects were observed for early and late maturing boys in the pathways between parent–child relationship quality and substance use. Pubertal timing moderated the pathway linking parent–child relationship quality with cigarette use 1 year later such that the association was stronger for late maturing girls compared with early and on‐time maturing girls. The findings indicate interplay between the psychosocial aspects of maturation, family relationships, and adolescent substance use and highlight possible gender‐specific influences.     

Randomized Controlled Trial of the Marriage Checkup: Depression Outcomes

The association between relationship functioning and depressive symptoms is well established. This study examined the effects of the Marriage Checkup, a brief two-session Assessment and Feedback relationship intervention, on depressive symptoms. Two hundred and nine married couples participated in the Marriage Checkup and were randomized into Treatment (N = 108) and Waitlist-Control Conditions (N = 101). Compared to the control condition, intervention participants reported significant improvements in depressive symptoms (d = 0.55), with an even greater effect for those who were reporting more severe baseline depression symptoms (d = 0.67). These outcomes are comparable to those within long-term individual psychotherapy, couple therapy, and pharmacology trials, making this the briefest intervention to date to demonstrate significant improvements in depressive symptoms. Clinical implications are discussed.     

The Role of Pubertal Timing in What Adolescent Boys Do Online

The aim of this study was to investigate associations between pubertal timing and boys' Internet use, particularly their viewing of pornography. We used a sample comprising of 97 boys in grade 8 (M age, 14.22 years) from two schools in a medium‐sized Swedish town. This age should be optimal for differentiating early, on‐time, and later‐maturing boys. Boys responded to self‐report questionnaires on their Internet use and pubertal timing. Early, on‐time, and late‐maturing boys did not differ in terms of most Internet activities. However, early maturers reported downloading and viewing pornography more often than the other boys did (p<.001). The findings build on previous research on the link between pubertal timing and sexual behavior in adolescence. Moreover, they help further understanding of the behavioral implications of boys' pubertal timing.     

Substance Abusing Mothers with a History of Childhood Abuse and Their Children's Depressive Symptoms: The Efficacy of Family Therapy

This study examined the associations among maternal history of childhood abuse, substance use, and depressive symptoms and the change in children's depressive symptoms in therapy. Mothers (N = 183) were randomly assigned into either a family or an individual treatment condition. Mothers were assessed for their childhood abuse retrospectively, baseline depressive symptoms, and substance use, whereas their children's depressive symptoms were measured five times during 1.5 years. Maternal childhood abuse was associated with a slower decline in child depressive symptoms through elevated maternal depressive symptoms, only in individual treatment. Maternal substance use further moderated this mediation pathway. This study supports the efficacy of family therapy in protecting children of mothers with a substance use disorder and a history of childhood abuse.     

The Impact of Pubertal Timing on Adolescents’ Alcohol Use

The relation between pubertal timing and alcohol use was investigated in a nationally representative sample (N= 4,686) of junior high school students who were followed up 2 years later (N= 3,862). Information regarding pubertal timing and status, sex‐role identification, number of alcohol intoxications, substance use, sexual behavior, friends’ alcohol use, and involvement in other types of problem behaviors was obtained. The results showed that early timing of pubertal development correlated with number of alcohol intoxications and number of units consumed on each occasion, and, to a lesser degree, with the frequency of alcohol use. Moreover, correlations were stronger among males than among females. Substantial parts of the association between pubertal timing and alcohol intoxications were mediated through friends’ problem behavior. Pubertal timing predicted alcohol use at follow‐up, but the effect was mostly due to increased alcohol intoxications at initial testing.
