Early Pubertal Timing as a Vulnerability to Depression Symptoms: Differential Effects of Race and Sex

Robust evidence supports that girls and boys who experience early pubertal timing, maturing earlier than one’s peers, are vulnerable to developing symptoms of depression. However, it has yet to be clarified whether early pubertal timing confers vulnerability to African American as well as to Caucasian adolescents and whether this vulnerability is specific to depressive symptoms or can be generalized to symptoms of social anxiety. In previous studies, one race or one sex was examined in isolation or sample sizes were too small to examine racial differences. Our longitudinal study consisted of a sample of 223 adolescents (M_age?=?12.42, 54.3 % female, 50.2 % African American, and 49.8 % Caucasian). At baseline, depressive symptoms, social anxiety symptoms, and pubertal timing were assessed by self-report. Nine months later, we assessed depressive symptoms, social anxiety symptoms, body esteem, and stressful life events that occurred between baseline and follow-up. Analyses indicated that early pubertal timing interacted with stressful life events to predict increased symptoms of depression, but only for Caucasian girls and African American boys. Results were found to be specific to depressive symptoms and did not generalize to symptoms of social anxiety. Additionally, there was a significant positive indirect effect of pubertal timing on symptoms of depression through body esteem for Caucasian females.     

Gene-environment interplay in the association between pubertal timing and delinquency in adolescent girls

Early pubertal timing places girls at elevated risk for a breadth of negative outcomes, including involvement in delinquent behavior. While previous developmental research has emphasized the unique social challenges faced by early maturing girls, this relation is complicated by genetic influences for both delinquent behavior and pubertal timing, which are seldom controlled for in existing research. The current study uses genetically informed data on 924 female-female twin and sibling pairs drawn from the National Longitudinal Study of Adolescent Health to (1) disentangle biological versus environmental mechanisms for the effects of early pubertal timing and (2) test for gene-environment interactions. Results indicate that early pubertal timing influences girls' delinquency through a complex interplay between biological risk and environmental experiences. Genes related to earlier age at menarche and higher perceived development significantly predict increased involvement in both nonviolent and violent delinquency. Moreover, after accounting for this genetic association between pubertal timing and delinquency, the impact of nonshared environmental influences on delinquency are significantly moderated by pubertal timing, such that the nonshared environment is most important among early maturing girls. This interaction effect is particularly evident for nonviolent delinquency. Overall, results suggest early maturing girls are vulnerable to an interaction between genetic and environmental risks for delinquent behavior.     

Interactive Effects of Psychosocial Stress and Early Pubertal Timing on Youth Depression and Anxiety: Contextual Amplification in Family and Peer Environments

While off-time pubertal development has emerged as a potential risk factor for both symptoms of depression and anxiety in youth, the literature is mixed and inconsistent as to (1) how early versus late pubertal timing confers risk for both boys and girls, (2) if the conferred risk is distinct between symptoms of anxiety and depression, and (3) under what social contexts (e.g., family environment, peer relationships) off-time pubertal development may emerge as a potent risk factor for these symptoms. The present study examined the impact of perceived pubertal timing on symptoms of anxiety and depression in two distinct psychosocial contexts: parent’s perceptions of their own harsh parenting and parent’s perceptions of their child’s peer problems. The sample consisted of 412 parents (M = 38.6 years old, SD = 7.8, 60.4 % mothers) of children between the ages of 8 and 17 (M = 12.13, SD = 2.97, 45.4 % girls). All constructs were assessed by parent reports. Linear multiple regression analyses revealed that the interaction between earlier pubertal timing and greater peer problems was significantly related to higher youth depressive and anxiety symptoms. The interaction between earlier pubertal timing and greater harsh discipline was significantly related to higher youth anxiety but not depressive symptoms. Youth gender did not qualify findings. Results suggest that the contextual amplification process of early pubertal timing may occur in both high stress family and peer environments and impact both girls and boys.     

Pubertal Timing and Youth Internalizing Psychopathology: The Role of Relational Aggression

The current study examined relational aggression as a potential mechanism that explains the association between off-time pubertal development and internalizing problems in youth. Youth gender was also examined as a moderator for the association between these variables. It was hypothesized that early pubertal maturation would be associated with higher levels of relationally aggressive behavior which, in turn, would be associated with elevated levels of internalizing problems. Parents of 372 children between the ages of 8 and 17 were recruited through Amazon’s Mechanical Turk. Parents responded to demographic information about themselves, as well as information about their child’s pubertal timing, relationally aggressive behavior, and anxiety and depressive symptoms. Findings indicated that early pubertal timing was associated with higher levels of anxiety directly, and higher levels of both anxiety and depressive symptoms indirectly through higher levels of relational aggression. In all but one of the pathways examined, gender was not found to moderate the associations between the study variables of interest. This study is the first to examine relational aggression as a mechanism by which early pubertal timing leads to internalizing problems. The findings suggest that relational aggression could be a target for intervention among early developing youth who are at risk for internalizing problems.     

It's about timing and change: pubertal transition effects on symptoms of major depression among African American youths

Effects of early physical maturation and accelerated pubertal changes on symptoms of major depression were examined in 639 African American children. Three rival hypotheses, early timing, off-time, and stressful change, were tested using 2 waves of data (mean ages = 11 and 13 years). The pubertal effect operates differently according to children's gender and age. For girls, early maturation was consistently associated with elevated levels of depressive symptoms. For boys, early maturers manifested elevated levels of depression only at age 11, but these symptoms subsided by age 13. Boys who experienced accelerated pubertal growth over time displayed elevated symptom levels. Results support the early timing hypothesis for girls and the stressful change hypothesis for boys. Time at assessment is critical when examining boys' pubertal transition.     

Effects of harsh parenting and positive parenting practices on youth aggressive behavior: The moderating role of early pubertal timing

Prior research indicates that early pubertal timing is associated with aggressive behavior, particularly in the context of adversity as postulated in the contextual amplification hypothesis. However, few studies have examined harsh parenting as the context for the effect of early pubertal timing. Even fewer studies have tested the interactive effect of early pubertal timing and positive parenting on aggressive behavior. In this study, we tested the proposition that early pubertal timing, contrary to the general conception of it as a vulnerability, indexed susceptibility, and thus early maturing individuals were affected more by their environment in a “for better and for worse” manner. The sample consisted of 411 community‐recruited youth aged 11–12 years (51% boys, 80% African Americans). Participants reported Tanner Stages of pubertal development, aggressive behavior and harsh parenting practice of their parents. Puberty scores were standardized with groups of the same age, sex, and ethnicity, and those that scored the top one‐third were defined as early maturing individuals. Parents reported youth's aggressive behavior and their parenting practices towards the youth, including harsh parenting and positive parenting. Early pubertal timing significantly moderated the relationship between harsh/positive parenting and aggressive behavior. Specifically, harsh parenting was positively associated with aggressive behavior to a larger degree among early maturing individuals than among on‐time/late‐maturing individuals. Positive parenting was inversely associated with aggressive behavior but only among early maturing individuals. This study is the first to document support for early pubertal timing as susceptibility to the environmental influences in relation to aggressive behavior. Theoretical and intervention implications are discussed.

     

Pubertal timing and self-esteem in adolescents: The mediating role of body-image and social relations

The aim of this study was to investigate the relationship between pubertal timing and self-esteem, and the mediating role of body-image, parent–adolescent interaction and peer support within this relationship. The sample comprised 526 adolescents, aged 10–13. Two measures of pubertal timing were used: perceived pubertal timing and pubertal timing based on Pubertal Development Scale (PDS). There were no differences in self-esteem between groups of adolescents with different pubertal timing based on PDS. Perceived early maturation was related to lower self-esteem in girls, and higher self-esteem in boys. We found evidence that the relationship between girls' perceived pubertal timing and self-esteem is mediated through the following variables: closeness to mother and father, and conflict with mother. In boys, mediators of the relationship between perceived pubertal timing and self-esteem are body-image and excessive control by mother. The results imply that interventions aiming to improve early maturing girls' self-esteem should focus on the interaction with their parents.     

The Interaction Between Pubertal Timing and Peer Popularity for Boys and Girls: An Integration of Biological and Interpersonal Perspectives on Adolescent Depression

The transition to adolescence marks a time of sharply increased vulnerability to the development of depression, particularly among girls. Past research has examined isolated risk factors from individual theoretical models (e.g., biological, interpersonal, and cognitive) of depression, but few have examined integrative models. This study investigated the conjoint effects of early pubertal timing and popularity in the longitudinal prediction of depressive symptoms. A total of 319 girls and 294 boys (ages 11–14) provided information on their pubertal status, depressive symptoms, and the social status (i.e., popularity) of their peers. Adolescents completed a second measure of depressive symptoms 11 months after the initial time point. Findings supported an integrated biological-interpersonal model in explaining the development of depressive symptoms during adolescence. Early pubertal development was associated with increase in depressive symptoms only when accompanied by low levels of popularity. High levels of popularity buffered the association between early pubertal development and later depressive symptoms. Unexpectedly, these results were significant both for girls and boys. Results are discussed in terms of dynamic systems theories.     

A longitudinal study of pubertal timing and extreme body change behaviors among adolescent boys and girls

Recent studies have examined the prevalence of disordered eating and other health risk behaviors among adolescent boys and girls. However, these studies generally have not examined predictors of these behaviors, and have not embedded the investigations within a theoretical framework. This study employed a longitudinal design to evaluate the validity of a biosocial model in explaining health risk behaviors related to extreme body change strategies (disordered eating, exercise dependence, use of food supplements, steroid use) among adolescents. The participants were 430 adolescent boys (mean age = 13.33 years) and 451 adolescent girls (mean age = 13.28 years) who completed measures of pubertal timing, perceived popularity with peers, body dissatisfaction, focus on sport, involvement in competitive sport, strategies to lose weight, strategies to increase muscle, disordered eating, use of food supplements and steroids, and exercise dependence. It was found that both early and late maturing girls were at greatest risk of engaging in health risk behaviors, whereas boys demonstrated more variability in the relationship between pubertal timing and extreme body change behaviors. The results of this study provide important insights into the role of pubertal development in the adoption of extreme body change behaviors among adolescents.

Morningness/eveningness, morning-to-afternoon cortisol ratio, and antisocial behavior problems during puberty

The relationship between morningness/eveningness (M/E) and morning-to-afternoon cortisol ratio, pubertal timing, and antisocial behavior was examined in 111 girls and boys ages 8 to 13 years. Cortisol levels showed a significant increase after awakening and declined thereafter (p<.05). Eveningness was related to a composite measure of antisocial behavior and rule-breaking and attention behavior problems and conduct disorder (CD) symptoms in boys and relational aggression in girls. In boys only, lower a.m. to p.m. cortisol ratio, indicating less circadian decrease in cortisol, was related to attention problems. Early pubertal timing was associated with boys' rule-breaking and attention behavior problems and CD symptoms and girls' relational aggression. The findings indicate that evening activity preference; extreme a.m. to p.m. cortisol ratios, in one case; and early pubertal timing were associated with antisocial behavior even in young adolescents, but the findings were stronger for boys than for girls.     

A longitudinal study of body dissatisfaction and pubertal timing in an ethnically diverse adolescent sample

In a 7-year study, adolescents’ body dissatisfaction (N = 1370) was examined across four high school years as a function of pubertal development (perceived timing relative to peers and self-reported physical changes measured during Grades 6–10) in the context of the high school transition. Boys and girls who, during early high school, perceived themselves to be late relative to peers were at risk for body dissatisfaction across the high school years. Boys who were late in pubertal development reported more body dissatisfaction in early high school than on-time boys, but then decreased over time. African-American girls reported less body dissatisfaction across the high school years relative to other girls. Asian girls reported more dissatisfaction in early high school than African-American, Latina, and Multiethnic girls, and increased over time. Results highlight the importance of considering late development within context as a risk factor in body dissatisfaction research.     

Social Anxiety and Peer Relations in Early Adolescence: Behavioral and Cognitive Factors

This study investigated factors associated with social anxiety during early adolescence using multiple informants, including self and peer perspectives, teacher ratings, and direct observations. Negative social performance expectations, maladaptive coping strategies, and social skill deficits were examined as correlates of social anxiety and mediators linking social anxiety with poor peer relations. Participants were 84 middle school students (47 girls, 37 boys) over-sampled for elevated social anxiety. Analyses revealed correlations linking social anxiety with decreased peer acceptance and increased peer victimization. Path analysis indicated that negative social performance expectations and social withdrawal-disengagement accounted for the association between social anxiety and decreased peer acceptance. Social anxiety, self-directed coping strategies, and social withdrawal-disengagement were each directly linked with increased peer victimization for boys. The results replicate findings based on clinical samples, extend understanding of cognitive, social, and behavioral factors associated with social anxiety in middle school, and provide new information regarding gender differences in the correlates of social anxiety.     

The impact of self-reported pubertal status and pubertal timing on disordered eating in irish adolescents

This paper considers the impact of pubertal status and pubertal timing on disordered eating in Irish adolescents. 1190 boys and 1841 girls completed the Eating Attitudes Test-26, the Eating Disorder Inventory-III and self-report measures of pubertal status and pubertal timing. Regarding pubertal status, greater maturity in girls was associated with increased overall eating concerns, higher drive for thinness and higher levels of body dissatisfaction. In boys, greater maturity was associated with lower drive for thinness and lower body dissatisfaction. Regarding pubertal timing, early-maturing girls showed the most eating concerns, the highest drive for thinness, scored highest on bulimic symptoms and were the most dissatisfied with their bodies. In contrast, late-maturing boys had more bulimic symptoms and more dissatisfaction with their bodies than on-time peers. The findings suggest that puberty itself is a risk factor for disordered eating for girls rather than boys; however, pubertal timing is a risk factor for both.

Distinguishing types of social withdrawal in children: Internalizing and externalizing outcomes of conflicted shyness versus social disinterest across childhood

Little research has examined the effect of subtypes of social withdrawal on the development of psychopathology across childhood.Parents of 493 children (220 females) completed a measure of their child’s conflicted shyness and social disinterest as well as the Child Behavior Checklist (CBCL) when their child was age 3, and again at age 6. When children were age 9, parents completed the CBCL.From 3 to 6, conflicted shyness predicted increases in anxiety symptoms in boys and girls, and predicted depressive symptoms in boys. From 6 to 9, social disinterest predicted increases in anxiety symptoms in girls and boys, and predicted increases in depressive symptoms in boys. In addition, in boys, conflicted shyness at age 6 predicted increases in externalizing symptoms at age 9.Conflicted shyness appears to be particularly problematic in early to middle childhood, while social disinterest appears to be more maladaptive in later childhood, with some differences by gender.     

Pubertal timing and substance use: associations between and within families across late adolescence

In the present study, between-family analyses of data from adolescent twin girls offer new evidence that early menarche is associated with earlier initiation and greater frequency of smoking and drinking. The role of personality factors and peer relationships in that association was investigated, and little support was found for their involvement. Novel within-family analyses replicating associations of substance use with pubertal timing in contrasts of twin sisters selected for extreme discordance for age at menarche are reported. Within-family replications demonstrated that the association of pubertal timing with substance use cannot be explained solely by between-family confounds. Within-family analyses demonstrated contextual modulation of the influence of pubertal timing: Its impact on drinking frequency is apparent only among girls in urban settings. Sibling comparisons illustrate a promising analytic tool for studying diverse developmental outcomes.     

The ABCs of depression: integrating affective, biological, and cognitive models to explain the emergence of the gender difference in depression

In adulthood, twice as many women as men are depressed, a pattern that holds in most nations. In childhood, girls are no more depressed than boys, but more girls than boys are depressed by ages 13 to 15. Although many influences on this emergent gender difference in depression have been proposed, a truly integrated, developmental model is lacking. The authors propose a model that integrates affective (emotional reactivity), biological (genetic vulnerability, pubertal hormones, pubertal timing and development) and cognitive (cognitive style, objectified body consciousness, rumination) factors as vulnerabilities to depression that, in interaction with negative life events, heighten girls' rates of depression beginning in adolescence and account for the gender difference in depression.     

Coping with Social Stress: Implications for Psychopathology in Young Adolescent Girls

This study investigated the impact of social stress on symptoms of psychopathology at the entry into adolescence (111 girls, Mage = 11.84, SD = 0.77). We examined whether peer stress and pubertal timing were associated with internalizing distress and aggression, and whether responses to stress and cortisol reactivity mediated or moderated these associations. Cortisol samples were collected from saliva samples during in-home visits, and the YSR was used to assess psychopathology. Interestingly, pubertal timing demonstrated a trend association with cortisol. Responses to stress mediated the association between social stress and symptoms of internalizing distress and aggression. Specifically, early maturers and girls with higher levels of peer stress exhibited more problematic responses to stress, in turn demonstrating higher levels of internalizing distress and aggression. Significant moderation effects also emerged. For example, early maturers who experienced higher levels of emotional/cognitive numbing in response to peer stress were at greater risk for aggression. Findings identify coping strategies that may be used in evidence-based programming to help girls transition more successfully into adolescence will be discussed.

A longitudinal examination of factors predicting anxiety during the transition to middle school

Abstract

The transition from elementary to middle or junior high school is commonly regarded as a period of stress and turmoil for young adolescents, and has been associated with changes in anxiety and other psychological problems. However, less is known about risk and resilience factors that may predict these changes. This study examined changes in anxiety, as well as predictors of these changes among 77, predominantly Caucasian (88%), male and female (52%) adolescents from Grades 6 to 8. Repeated measures analysis of variance was conducted to examine the predicted grade and gender differences. Multiple regression analyses were conducted to examine the prediction of eighth grade anxiety symptoms by sixth grade self-worth, perceived social acceptance, and social support, as well as the potential moderating role of gender in these relations. Results suggested a significant decrease in anxiety, particularly social anxiety, over this period for boys but not girls. Examination of predictors of changes in anxiety suggested that, in general, global self-worth, social acceptance, and gender were each associated with overall and social anxiety. Findings are integrated with extant literature on developmental changes associated with anxiety and school transitions and clinical implications of these findings are discussed.     

Scores on the State-Trait Anxiety Inventory for children in a longitudinal study of pubertal Spanish youth.

Changes in scores on the State-Trait Anxiety Inventory for Children for a sample of 534 pubertal adolescents were longitudinally studied over a period of 4 years. Biological development and other variables were investigated. For the 310 boys, A-trait scores decreased significantly with age. The 224 girls showed significantly higher scores than boys in all years of the study. No significant relationship was found between anxiety and pubertal maturity. The year-to-year persistence in symptomatology of anxiety ranged between 55.6% and 66.1% for girls and between 48.5% and 53.1% for boys. Girls showed bi- and tri-annual persistence between 31% and 50%, and boys between 13% and 27%. Neuroticism scores formed the best predictor of A-trait scores. Symptomatology of anxiety is not transient during early adolescence, so personality may provide a risk indicator in the development of anxiety.
