Developmental Trajectories and Predictors of Externalizing Behavior: A Comparison of Girls and Boys

Recent studies have shown that the development of externalizing behavior in childhood and adolescence can be described through different developmental pathways. However, knowledge about differences between the sexes regarding the trajectories is limited. This study focused on potential differences by examining the trajectories of self-reported externalizing symptoms for girls and boys separately. In addition, the relationships of several familiar and child-specific variables with those developmental courses were assessed. The study was conducted on a large community sample of German youths (N = 3,893; mean age 11.38 years; 50 % girls) over 4 years. Using growth mixture modeling, three different classes of trajectories were found for both sexes. The classes differed with regard to the level and the course of symptoms (“low”, “moderate”, “high-decreasing”). Girls were overrepresented in the “low” class, whereas boys were predominant in the “moderate” and “high-decreasing” classes. The multiple group analysis revealed that the girls and boys differed significantly in their level and linear course of symptoms with regard to the “high-decreasing” class. In contrast, no sex differences were found in the growth factors of the “low” and “moderate” classes. The regression analyses showed that the children’s depressive symptoms, dysfunctional parenting style, and negative family climate were associated significantly with the level and course of symptoms as well as the class membership of girls and boys. Life events predicted class membership only for boys, whereas maternal depressive symptoms and family conflict did not demonstrate any significant relationship. The sizes of the predictive associations with the growth factors were similar for both sexes. The results are discussed with regard to existing developmental models and their possible implications for prevention and future research.     

Bidirectional Influences Between Dimensions of Coparenting and Adolescent Adjustment

Research on coparenting documents that mothers’ and fathers’ coordination and mutual support in their parenting roles is linked to their offspring’s adjustment in childhood, but we know much less about the coparenting of adolescents. Taking a family systems perspective, this study assessed two dimensions of coparenting, parents’ shared decision-making and joint involvement in activities with their adolescents, and examined bidirectional associations between these coparenting dimensions and boys’ and girls’ risky behaviors and depressive symptoms across four time points (6 years) in adolescence. Participants were 201 mothers, fathers, and adolescents (M = 11.83, SD = .55 years of age at Time 1; 51 % female). Parents of sons shared more decisions, on average, than parents of daughters. On average, shared decision-making followed an inverted U shaped pattern of change, and parents’ joint involvement in their adolescents’ activities declined. Cross-lagged findings revealed that risky behavior predicted less shared decision-making, and shared decision-making protected against increased risky behavior for boys. For girls and boys, parents’ joint involvement predicted fewer risky behaviors, and lower levels of risky behavior predicted higher levels of joint involvement. In contrast, boys’ and girls’ depressive symptoms predicted less joint involvement. The discussion centers on the nature and correlates of coparenting during adolescence, including the role of child effects, and directions for future research on coparenting during this developmental period.     

Gender Moderation of the Intergenerational Transmission and Stability of Depressive Symptoms from Early Adolescence to Early Adulthood

Factors that might exacerbate or mitigate the transmission of depressive symptoms from parents to adolescents and the continuity of depressive symptoms into early adulthood are poorly understood. This study tested the hypothesis that the intergenerational transmission and stability of depressive symptoms would be stronger for girls than boys over adolescence and into early adulthood, while considering the possibility that the pattern of gender moderation might vary depending on parent gender and developmental timing. The participants were 667 rural Midwestern adolescents (52 % female) and their parents. Survey data on maternal and paternal depressive symptoms (at youth age 11) and on adolescent and young adult depressive symptoms (at youth ages 11, 18, and 21) were analyzed via multiple group structural equation modeling. Maternal depressive symptoms predicted increased late adolescent depressive symptoms for girls but not boys, and adolescent depressive symptoms were more stable in girls. Paternal depressive symptoms predicted increased late adolescent depressive symptoms for all youth. The findings suggest the need for early, tailored interventions.     

Acculturation, Enculturation, and Symptoms of Depression in Hispanic Youth: The Roles of Gender, Hispanic Cultural Values, and Family Functioning

The risk for depression increases as Hispanic youth acculturate to U.S. society. This association is stronger for Hispanic girls than boys. To better understand the influence of culture and family on depressive symptoms, we tested a process-oriented model of acculturation, cultural values, and family functioning. The data came from Project RED, which included 1,922 Hispanic students (53?% girls; 86?% were 14?years old; and 84?% were U.S. born) from Southern California. We used data from 9th to 11th grade to test the influence of acculturation-related experiences on depressive symptoms over time. Multi-group structural equation analysis suggested that both family conflict and cohesion were linked with depressive symptoms. Hispanic cultural values were associated with family cohesion and conflict but the strength and direction of these relationships varied across cultural values and gender. For girls and boys, familismo and respeto were associated with higher family cohesion and lower family conflict. Moreover, gender roles were linked with higher family cohesion in girls but not in boys. These results indicate that improving family functioning will be beneficial for boys' and girls' psychological well-being. This may be achieved by promoting familismo and respeto for boys and girls and by promoting traditional gender roles for girls.     

Non-Suicidal Self-Injury and Depressive Symptoms During Middle Adolescence: A Longitudinal Analysis

Previous research has shown a consistent positive association between non-suicidal self-injury and depressive symptoms. However, the direction of the effects has not been examined. To understand whether non-suicidal self-injury predicts depressive symptoms or vice versa, we examined the relations between non-suicidal self-injury and depressive symptoms across three waves of self-report data collected 1 year apart from 506 Swedish adolescents (47 % girls; M age = 13.21; SD = .57) who were attending 7th grade at the onset of the study. The results suggest that depressive symptoms predict increases in non-suicidal self-injury 1 year later between the first and second waves of the study. Between the second and third waves of the study depressive symptoms and non-suicidal self-injury were significantly correlated indicating co-occurrence with no direction of effect rather than depressive symptoms predicting non-suicidal self-injury or vice versa. Group comparisons revealed no differences for boys and girls. The findings help clarify the relationships between non-suicidal self-injury and depressive symptoms during middle adolescence.     

Parental Monitoring, Parental Warmth, and Minority Youths’ Academic Outcomes: Exploring the Integrative Model of Parenting

Guided by the integrative model of parenting, the present study investigated the relationship between parental monitoring and racial/ethnic minority adolescents’ school engagement and academic motivation as a function of parental warmth, and explored whether these associations varied for boys and girls. Participants (60 % female) were 208 sixth through eighth grade students (63 % African American, 19 % Latino, 18 % Multiracial) from an urban middle school in the Midwestern United States. Youth completed an in-school survey with items on parenting (parental monitoring, mothers’/fathers’ warmth), cognitive engagement (school self-esteem), behavioral engagement (school trouble), and academic motivation (intrinsic motivation). As hypothesized, mothers’ warmth enhanced the association between parental monitoring and youths’ engagement and motivation. No gender differences in these associations emerged. Fathers’ warmth strengthened the negative association between parental monitoring and school trouble, and this association was stronger for boys. Implications regarding the importance of sustaining a high level of monitoring within the context of warm parent–adolescent relationships to best support academic outcomes among minority youth are discussed.     

Gender-Specific Relationships Between Depressive Symptoms, Marijuana Use, Parental Communication and Risky Sexual Behavior in Adolescence

A large body of research has identified correlates of risky sexual behavior, with depressive symptoms and marijuana use among the most consistent psychosocial predictors of sexual risk. However, substantially less research has examined the relationship between these risk variables and adolescent risky sexual behavior over time as well as the interaction of these individual-level predictors with family-level variables such as parenting factors. Additionally, most studies have been restricted to one index of risky sexual behavior, have not taken into account the complex role of gender, and have not controlled for several of the factors that independently confer risk for risky sexual behavior. Therefore, the current study investigated the association between depressive symptoms and parameters of parenting on marijuana use, number of sexual partners and condom usage measured 9 months later for both boys and girls. Participants were 9th and 10th grade adolescents (N = 1,145; 57.7 % female). We found that depressive symptoms may be a gender-specific risk factor for certain indices of risky sexual behavior. For boys only, marijuana use at Time 2 accounted for the variance in the relationship between depressive symptoms at Time 1 and number of partners at Time 2. Additionally, strictness of family rules at Time 1 was associated with the number of partners with whom girls engaged in sex at Time 2, but only among those with lower levels of depressive symptoms at Time 1. Results from the current investigation speak to the utility of examining the complex, gender-specific pathways to sexual risk in adolescents. Findings suggest that treatment of mental health and substance use problems may have important implications in rates of risky sexual behavior and, conceivably, controlling the high rates of serious individual and public health repercussions.     

Race and Perceived Pubertal Transition Effects on Girls’ Depressive Symptoms and Delinquent Behaviors

Most past research on the effects of early pubertal timing on girls’ depressive symptoms and delinquent behavior has focused on either age of menarche or has combined multiple indicators of development into a single index of puberty. Past research has rarely examined both the onset of puberty such as age of menarche, as well more psychologically mediated impressions of puberty (i.e., perceived pubertal timing) within the same study. This study extends past research on racial differences and pubertal related effects on girls’ depressive symptoms and delinquent behavior by examining the independent influence of different indicators of puberty (age of menarche, development of breasts, and perceived pubertal timing). Two waves of data (100 % females) were used from African Americans (N = 481) and European Americans (N = 1259) who were enrolled in seventh- and eighth-grade during the first wave of data collection in the National Longitudinal Study of Adolescent Health. Early age of menarche was associated with high levels of depressive symptoms at Wave 1. Additionally, both early and late perceived pubertal timing were associated with high levels of depressive symptoms and high delinquent behaviors at Wave 1. The structural relationships among these variables were similar for African Americans and European Americans. Age of menarche and perceived pubertal timing influenced depressive symptoms and delinquent behavior at Wave 2 through depressive symptoms and delinquent behavior reported at Wave 1. The implications of these findings are discussed with an emphasis on how the specific indicator used to assess puberty is important in efforts to understand pubertal timing effects.     

Mothers’ and Fathers’ Autonomy-Relevant Parenting: Longitudinal Links with Adolescents’ Externalizing and Internalizing Behavior

The goal of this study was to advance the understanding of separate and joint effects of mothers’ and fathers’ autonomy-relevant parenting during early and middle adolescence. In a sample of 518 families, adolescents (49 % female; 83 % European American, 16 % African American, 1 % other ethnic groups) reported on their mothers’ and fathers’ psychological control and knowledge about adolescents’ whereabouts, friends, and activities at ages 13 and 16. Mothers and adolescents reported on adolescents’ externalizing and internalizing behaviors at ages 12, 14, 15, and 17. Adolescents perceived their mothers as using more psychological control and having more knowledge than their fathers, but there was moderate concordance between adolescents’ perceptions of their mothers and fathers. More parental psychological control predicted increases in boys’ and girls’ internalizing problems and girls’ externalizing problems. More parental knowledge predicted decreases in boys’ externalizing and internalizing problems. The perceived levels of behavior of mothers and fathers did not interact with one another in predicting adolescent adjustment. The results generalize across early and late adolescence and across mothers’ and adolescents’ reports of behavior problems. Autonomy-relevant mothering and fathering predict changes in behavior problems during early and late adolescence, but only autonomy-relevant fathering accounts for unique variance in adolescent behavior problems.     

Chronic Family Economic Hardship, Family Processes and Progression of Mental and Physical Health Symptoms in Adolescence

Research has documented the relationship between family stressors such as family economic hardship and marital conflict and adolescents’ mental health symptoms, especially depressive symptoms. Few studies, however, have examined the processes whereby supportive parenting lessens this effect and the progression of mental health and physical health symptoms in adolescence. The present study investigates the influences of chronic family economic hardship on adolescents’ multiple health problem symptoms (i.e., symptoms of anxiety, and depression and physical complaints) through parents’ marital conflict, and supportive parenting; it also examines how there adolescents’ health problems mutually influence one another throughout adolescence. We used Structural Equation Modeling to analyze data from a longitudinal sample of European American mothers, fathers, and target adolescents (N = 451, 53 % female) to examine direct and indirect effects. Findings generally supported the hypothesized model. Chronic family economic hardship contributed to mental and physical health problems of adolescents. This influence largely was mediated through supportive parenting. Moreover, supportive parenting buffered marital conflict on depressive symptoms of adolescents. Also, there was a tendency for females to show more stable depressive symptoms than males. The study demonstrates key mediating pathways and additional moderating influences based on the family stress model and also highlights the importance of improving health resources for adolescents.     

Pubertal Development Moderates the Importance of Environmental Influences on Depressive Symptoms in Adolescent Girls and Boys

Prevalence differences in depressive symptoms between the sexes typically emerge in adolescence, with symptoms more prevalent among girls. Some evidence suggests that variation in onset and progression of puberty might contribute to these differences. This study used a genetically informative, longitudinal (assessed at ages 12, 14, and 17) sample of Finnish adolescent twins (N = 1214, 51.6% female) to test whether etiological influences on depressive symptoms differ as a function of pubertal status. These tests were conducted separately by sex, and explored longitudinal relationships. Results indicated that pubertal development moderates environmental influences on depressive symptoms. These factors are more important on age 14 depressive symptoms among more developed girls relative to their less developed peers, but decrease in influence on age 17 depressive symptoms. The same effects are observed in boys, but are delayed, paralleling the delay in pubertal development in boys compared to girls. Thus, the importance of environmental influences on depressive symptoms during adolescence changes as a function of pubertal development, and the timing of this effect differs across the sexes.     

How is Anxiety Involved in the Longitudinal Relationship between Brooding Rumination and Depressive Symptoms in Adolescents?

A growing body of research supports the application of Response Styles Theory to adolescent populations. Although the essential dynamic, namely that rumination increases the incidence of depressive symptoms, has been demonstrated among adolescents, a number of important empirical questions remain, such as: what are the gender differences and developmental trends for brooding and reflective rumination?; does a reciprocal relationship exist between brooding or reflective rumination, on the one hand, and depressive symptoms and anxiety, on the other hand, over time? and how do additional variables (i.e., anxiety) impact upon the rumination-depressive symptoms relationship? In this study, self-reported levels of rumination (both brooding and reflective), and anxious and depressive symptoms were measured longitudinally across 4 months in a sample of 976 community adolescents (46 % females), aged 11–16 years old. Mean group differences showed that female adolescents reported engaging in more brooding rumination than male adolescents beginning at 13 years of age. A reciprocal brooding rumination to depressive symptoms relationship and a reciprocal brooding rumination to anxiety relationship were found over time, and they did not differ for boys and girls. We tested the possibility that anxious symptoms would function as a third variable, but the obtained model showed that brooding rumination and anxiety both contributed unique variance in predicting changes in depressive symptoms over time.     

Concurrent Trajectories of Change in Adolescent and Maternal Depressive Symptoms in the TORDIA Study

Depression has a heightened prevalence in adolescence, with approximately 15 % of adolescents experiencing a major depressive episode by age 18. Depression in adolescence also poses a risk for future distress and impairment. Despite treatment advances, many adolescents relapse after initial remission. Family context may be an important factor in the developmental trajectory of adolescent depression, and thus in enhancing treatment. This study examined concurrent change over time in adolescent and maternal depressive symptoms in the context of the Treatment of Resistant Depression in Adolescents study. Participants were 334 adolescents (mean age: 16; SD: 1.6; 70 % female, 84 % Caucasian), and their mothers (n = 241). All adolescents were clinically depressed when they entered the study and had received previous selective serotonin reuptake inhibitor (SSRI) treatment. Adolescents received acute treatment for 12 weeks and additional treatment for 12 more weeks. Adolescent depression and suicidal ideation were assessed at 0, 6, 12, 24, 48 and 72 weeks, while maternal depressive symptoms were assessed at 0, 12, 24, 48 and 72 weeks. Latent basis growth curve analyses showed a significant correlation over 72 weeks between trajectories of maternal and adolescent depressive symptoms, supporting the hypothesis of concurrent patterns of change in these variables. The trajectories were correlated more strongly in a subsample that included only dyads in which mothers reported at least one depressive symptom at baseline. Results did not show a correlation between trajectories of maternal depressive symptoms and adolescent suicidal ideation. These findings suggest that adolescent and maternal depressive symptoms change in tandem, and that treatment for adolescent depression can benefit the wider family system. Notably, most mothers in this sample had subclinical depressive symptoms. Future research might explore these trajectories in dyads with more severely depressed mothers.     

Sleep Disturbance and Depressive Symptoms in Adolescence: The Role of Catastrophic Worry

Depression is a common and debilitating disorder in adolescence. Sleep disturbances and depression often co-occur with sleep disturbances frequently preceding depression. The current study investigated whether catastrophic worry, a potential cognitive vulnerability, mediates the relationship between adolescent sleep disturbances and depressive symptoms, as well as whether there are gender differences in this relationship. High school students, ages 16–18, n = 1,760, 49 % girls, completed annual health surveys including reports of sleep disturbance, catastrophic worry, and depressive symptoms. Sleep disturbances predicted depressive symptoms 1-year later. Catastrophic worry partially mediated the relationship. Girls reported more sleep disturbances, depressive symptoms, and catastrophic worry relative to boys. The results, however, were similar regardless of gender. Sleep disturbances and catastrophic worry may provide school nurses, psychologists, teachers, and parents with non-gender specific early indicators of risk for depression. Several potentially important practical implications, including suggestions for intervention and prevention programs, are highlighted.     

Psychological Symptoms Linking Exposure to Community Violence and Academic Functioning in African American Adolescents

African American adolescents are exposed disproportionately to community violence, increasing their risk for emotional and behavioral symptoms that can detract from learning and undermine academic outcomes. The present study examined whether aggressive behavior and depressive and anxious symptoms mediated the association between exposure to community violence and academic functioning, and if the indirect effects of community violence on academic functioning differed for boys and girls, in a community sample of urban African American adolescents (N = 491; 46.6 % female). Structural equation modeling was used to examine the indirect effect of exposure to community violence in grade 6 on grade 8 academic functioning. Results revealed that aggression in grade 7 mediated the association between grade 6 exposure to community violence and grade 8 academic functioning. There were no indirect effects through depressive and anxious symptoms, and gender did not moderate the indirect effect. Findings highlight the importance of targeting aggressive behavior for youth exposed to community violence to not only improve their behavioral adjustment but also their academic functioning. Implications for future research are discussed.     

Parental Depressive Feelings, Parental Support, and the Serotonin Transporter Gene as Predictors of Adolescent Depressive Feelings: A Latent Growth Curve Analysis

Parental support and parental depressive feelings are found to be associated with depressive feelings in adolescent boys and girls, but results are inconsistent. In addition, the 5-HTTLPR genotype has been found to interact with environmental stressors in predicting adolescents?? depressive feelings, but this has not been examined longitudinally. Therefore, the present study examined the relationships between parental support, parental depressive feelings, and adolescent depressive feelings. In addition, the relationships between the 5-HTTLPR genotype and adolescent depressive feelings were explored, as well as gene-environment interactions. Adolescents (N = 306; Girls = 53.3%; M _{age T1} = 13.4) filled out questionnaires at five annual waves and provided saliva samples for DNA. Latent growth curve modelling (LGCM) was used to examine the baseline level and the change in depressive feelings over time. Maternal support was related to baseline levels of depressive feelings in girls, whereas paternal support was related to baseline levels in boys. Paternal depressive feelings were only related to boys?? depressive feelings at baseline, and maternal depressive feelings were not related to any outcome measures. Furthermore, no associations were found between 5-HTTLPR genotype and adolescent depressive feelings, and no gene-environment interactions emerged. Limitations of the study and implications of the findings are discussed.     

Gender-related Risk and Protective Factors for Depressive Symptoms and Disordered Eating in Adolescence: A 4-year Longitudinal Study

The interplay between intrapersonal risk (low self-esteem, perfectionism and body dissatisfaction) and interpersonal protection (social support) appears relevant for delineating gender-specific pathways that lead to both depressive and eating psychopathology. The aims of this longitudinal study were to examine gender differences in the levels of depressive symptoms, disordered eating and the co-occurrence of both problems from preadolescence to mid-adolescence and to identify gender-specific risk and protective factors of depressive symptoms and disordered eating. A Spanish community-based sample initially comprising 942 early adolescents (49% females) was assessed at baseline (T1; X _age = 10.8 years) and at 2 and 4-year follow-up (T2 and T3). Gender differences emerged at T2 for disordered eating and at T3 for depressive symptoms and for co-occurring depressive symptoms and disordered eating. Predictors of depressive symptoms were body dissatisfaction, low self-esteem and fear of getting fat, for girls, and body dissatisfaction and low self-esteem, for boys. Predictors of disordered eating were body dissatisfaction, depressive symptoms, BMI and perfectionism, for girls, and low social support and BMI, for boys. In addition, for boys only, social support moderated the effect of body dissatisfaction on depressive symptoms and the effect of depressive symptoms on disordered eating. The hypotheses of the study were partially supported. Clinical implications are derived regarding the components that should be included in programs for preventing depression and eating disorders in both girls and boys.     

Self-Concept Clarity Across Adolescence: Longitudinal Associations With Open Communication With Parents and Internalizing Symptoms

Higher self-concept clarity is related to several adjustment indices and may be promoted by open communication with parents, while problems with self-concept clarity development could enhance internalizing problems (i.e., depressive and anxiety symptoms) in adolescence. This longitudinal study examined linkages between self-concept clarity, adolescents’ open communication with parents, and adolescent depressive and anxiety symptoms. Dutch youths (N = 323; 51.1 % girls; mean age Time 1 = 13.3 years) reported on these constructs over four consecutive annual measurements. Concurrent positive links between open communication and self-concept clarity were found at Time 1. Over time, higher levels of open communication with parents predicted higher self-concept clarity only in middle adolescence (mean age between 14 and 15 years). We also found concurrent associations between self-concept clarity and both depressive and anxiety symptoms. Longitudinally, lower self-concept clarity predicted relatively higher levels of depressive symptoms across all waves, and also higher anxiety levels from Time 1 to Time 2. Conversely, higher levels of anxiety also predicted lower levels of self-concept clarity during the first three waves. Self-concept clarity did not mediate the longitudinal associations between open communication and internalizing symptoms. This study is one of the first to investigate self-concept clarity across adolescence. It highlights the possible importance of both anxiety symptoms and communication with parents in understanding the development of a clear self-concept, and demonstrates an association between lower self-concept clarity and higher levels of later depressive and anxiety symptoms.     

Deficits in Emotional Clarity and Vulnerability to Peer Victimization and Internalizing Symptoms Among Early Adolescents

Peer victimization is a significant risk factor for a range of negative outcomes during adolescence, including depression and anxiety. Recent research has evaluated individual characteristics that heighten the risk of experiencing peer victimization. However, the role of emotional clarity, or the ability to understand one’s emotions, in being the target of peer victimization remains unclear. Thus, the present study evaluated whether deficits in emotional clarity increased the risk of experiencing peer victimization, particularly among adolescent girls, which, in turn, contributed to prospective levels of depressive and anxiety symptoms. In the present study, 355 early adolescents (ages 12–13; 53 % female; 51 % African American) who were part of the Adolescent Cognition and Emotion project completed measures of emotional clarity, depressive symptoms, and anxiety symptoms at baseline, and measures of peer victimization, depressive symptoms, and anxiety symptoms at follow-up. Moderation analyses indicated that deficits in emotional clarity predicted greater peer victimization among adolescent girls, but not adolescent boys. Moderated mediation analyses revealed that deficits in emotional clarity contributed to relational peer victimization, which, in turn, predicted prospective levels of depressive and anxiety symptoms among adolescent girls, but not boys. These findings indicate that deficits in emotional clarity represent a significant risk factor for adolescent girls to experience relational peer victimization, which, in turn, contributed to prospective levels of internalizing symptoms. Thus, prevention programs should target deficits in emotional clarity to prevent peer victimization and subsequent internalizing symptoms among adolescent girls.
