Individual differences in the emergence of depressive symptoms in children and adolescents: a longitudinal investigation of parent and child reports

The authors address questions about the rate that depressive symptoms emerge, developmental and gender differences in this rate, and differences between parent and child estimates of this rate. In a 12-wave, cohort-sequential, longitudinal design, 1,570 children (Grades 4-11) and parents completed reports about children's depression. Cross-domain latent growth curve analysis revealed that (a) the rate of symptom growth varied with developmental level. (b) gender differences symptom growth preceded emergence of mean level gender differences, (c) the rate of symptom development varied with age, and (d) parent-child agreement about rate of symptom change was stronger than agreement about time-specific symptoms. The authors suggest that predictability of depressive symptoms varies with age and the dimension under investigation.     

Conduct Problems, Depressive Symptomatology and Their Co-Occurring Presentation in Childhood as Predictors of Adjustment in Early Adolescence

The present study investigated patterns in the development of conduct problems (CP), depressive symptoms, and their co-occurrence, and relations to adjustment problems, over the transition from late childhood to early adolescence. Rates of depressive symptoms and CP during this developmental period vary by gender; yet, few studies involving non-clinical samples have examined co-occurring problems and adjustment outcomes across boys and girls. This study investigates the manifestation and change in CP and depressive symptom patterns in a large, multisite, gender-and ethnically-diverse sample of 431 youth from 5th to 7th grade. Indicators of CP, depressive symptoms, their co-occurrence, and adjustment outcomes were created from multiple reporters and measures. Hypotheses regarding gender differences were tested utilizing both categorical (i.e., elevated symptom groups) and continuous analyses (i.e., regressions predicting symptomatology and adjustment outcomes). Results were partially supportive of the dual failure model (Capaldi, 1991, 1992), with youth with co-occurring problems in 5th grade demonstrating significantly lower academic adjustment and social competence two years later. Both depressive symptoms and CP were risk factors for multiple negative adjustment outcomes. Co-occurring symptomatology and CP demonstrated more stability and was associated with more severe adjustment problems than depressive symptoms over time. Categorical analyses suggested that, in terms of adjustment problems, youth with co-occurring symptomatology were generally no worse off than those with CP-alone, and those with depressive symptoms-alone were similar over time to those showing no symptomatology at all. Few gender differences were noted in the relations among CP, depressive symptoms, and adjustment over time.     

Gender and age differences in emotion regulation strategies and their relationship to depressive symptoms

We examined differences between men and women, and between young, middle and older age adults in emotion regulation strategies (rumination, suppression, reappraisal, problem-solving, acceptance, social support) and the relationships between these strategies and depressive symptoms. Women were more likely than men to report using several different emotion regulation strategies, and these gender differences were significant even after statistically controlling for gender differences in depressive symptoms. Use of most strategies decreased with age, with two exceptions: (1) use of suppression increased with age for women but not for men and (2) use of acceptance did not decrease with age for women. Use of maladaptive strategies was associated with more depressive symptoms in all age groups and both genders, yet, the use of adaptive strategies generally was not related to lower levels depressive symptoms across groups.     

GENDER DIFFERENCES IN DEPRESSIVE SYMPTOMS

Large community studies of depressive symptomatology provide mixed evidence concerning gender differences. The present paper investigates the effect of the high skewness typically present in distributions of depressive symptom scores on findings of a gender difference in depression. Because of this skewness, a few extreme scores among women (or in any subgroup) can produce a significant between-groups difference in untransformed scores even when the two groups' distributions are otherwise similar. Data from a community survey ( n = 1316) are consistent with this hypothesis. The data also suggest that gender increases depression scores indirectly, rather than directly, for the few women scoring in the extreme upper tail of the distribution. It is concluded that the gender difference in depressive symptoms lacks robustness, and that when it does occur, the effect of gender on depression can be understood as ndirect, i.e., as mediated by gender differences in rate of employment, job status, education, and income.     

Pubertal transition, stressful life events, and the emergence of gender differences in adolescent depressive symptoms

This study examined the role of both pubertal and social transitions in the emergence of gender differences in depressive symptoms during adolescence. This study generated the following findings: (a) Gender differences in depressive symptoms emerged during 8th grade and remained significant through 12th grade. (b) Pubertal status in 7th grade was related to adolescent depressive symptoms over time. (c) Early-maturing girls represented the group with the highest rate of depressive symptoms. (d) Depressive symptoms measured in 7th grade predicted subsequent symptom levels throughout the secondary school years. (e) Recent stressful life events were associated with increased depressive symptoms. (f) Early-maturing girls with higher levels of initial symptoms and more recent stressful life events were most likely to be depressed subsequently. The findings demonstrate the importance of the interaction between the pubertal transition and psychosocial factors in increasing adolescent vulnerability to depressive experiences.     

Co-rumination predicts the onset of depressive disorders during adolescence

The tendency to co-ruminate, or frequently discuss and rehash problems with peers, may serve as one mechanism in the dramatic rise in depression observed during adolescence, particularly among adolescent girls. In the current study, our goal was (a) to test the hypothesis that adolescents' levels of co-rumination would predict the onset of clinically significant depressive episodes over a 2-year follow-up and (b) to determine whether levels of co-rumination would mediate gender differences in risk for depression onset. Both hypotheses were supported. Results of survival analysis revealed that adolescents with higher levels of co-rumination at the initial assessments exhibited a significantly shorter time to depression onset. Levels of co-rumination also mediated the gender difference in time to depression onset. These results were maintained even when adolescents' baseline levels of depressive symptoms and rumination were covaried statistically. Finally, co-rumination also predicted the course of illness in terms of episode severity and duration. Results suggest that co-rumination contributes a unique risk for the development of depression in adolescents.     

Gender differences in emotional support and depressive symptoms among adolescents: A prospective analysis

Investigated components of perceived emotional support, including support from family members, nonfamily adults, and peers, as predictors of depressive symptoms in a sample of 333 high school students (age 14-18) using a prospective design. Analyses of panel questionnaire data at two points in time suggest there are significant gender differences both in the quality of perceived support reported by adolescents and in the importance of support variables as predictors of depressive symptoms. Although there are no gender differences in the magnitude of perceived support from family members, girls report higher emotional support from both nonfamily adults and peers than boys report. Simple correlations between family support and depression are significantly stronger for girls than for boys. Results of hierarchical regression analyses, controlling for initial level of symptoms, reveal that whereas both nonfamily adult and friend components of perceived support are significant predictors of changes in symptoms for girls, none of these variables significantly predicts changes in symptoms for boys in this sample. In addition, initial symptoms predict changes in family support for girls but not for boys.     

Childhood Social Withdrawal,Interpersonal Impairment,and Young Adult Depression: A Mediational Model

Building on interpersonal theories of depression, the current study sought to explore whether early childhood social withdrawal serves as a risk factor for depressive symptoms and diagnoses in young adulthood. The researchers hypothesized that social impairment at age 15 would mediate the association between social withdrawal at age 5 and depression by age 20. This mediational model was tested in a community sample of 702 Australian youth followed from mother’s pregnancy to youth age 20. Structural equation modeling analyses found support for a model in which childhood social withdrawal predicted adolescent social impairment, which, in turn, predicted depression in young adulthood. Additionally, gender was found to moderate the relationship between adolescent social impairment and depression in early adulthood, with females exhibiting a stronger association between social functioning and depression at the symptom and diagnostic level. This study illuminates one potential pathway from early developing social difficulties to later depressive symptoms and disorders.     

Protective Effects of Maternal and Peer Support on Depressive Symptoms during Adolescence

The current study examined the contributions of maternal and peer support to depressive symptoms in early to mid-adolescence and variation in these contributions across age, gender, and race. Five waves of data on maternal support, peer support, and depressive symptoms were collected on rural youth (N = 3,444) at 6 month intervals. Multilevel modeling was used to evaluate within and between-person effects of maternal and peer support on depressive symptoms. Within-person effects of peer support did not vary by age, gender, or race. At the between-person level, peer support predicted levels of depressive symptoms at age 12, but this effect became nonsignificant after controlling for maternal support. Within-person effects of maternal support did not vary with age but were qualified by gender and race. Between-person effects of maternal support on depressive symptom levels at age 12 and slopes varied across race and gender, respectively. Findings highlight the robustness of the protective effects of maternal and peer support during adolescence among girls and white youth.     

The symptomatic expression of major depressive disorder in adolescents and young adults

Data from the Oregon Adolescent Depression Project were used to examine the symptomatic expression of major depressive disorder (MDD) as a function of age and gender. The objective was to investigate the phenomenological nature of MDD among a cohort of adolescents as they progressed into early adulthood. The analyses were based on 564 participants who had experienced MDD in their lifetime. No systematic differences in the relative rate of occurrence of specific symptoms across episodes and only minor symptom differences between male and female participants were found. Age did not significantly influence the symptom picture. Stability of specific symptoms and episode severity across episodes was low. The results are discussed within the context of a stressor-symptom matching model.     

The relationship between spirituality and depressive symptom severity,psychosocial functioning impairment,and quality of life: examining the impact of age,gender, and ethnic differences

Research has documented the contribution of spirituality on overall health and mental health among college students. However, very few studies have explored the impact of cultural and ethnic differences on the effect of spirituality on mental health outcomes in this population. The aims of this study were to examine the relationships among spirituality, depressive symptom severity, psychosocial functioning impairment, and quality of life in a large multi-ethnic sample of college students and explore the impact of age, gender, and ethnicity on these relationships. The sample consisted of Latino, African-American, Caucasian, and Caribbean/West Indian college students. Findings indicated that spirituality, believing in God's presence, age, gender, and ethnicity were significantly related to depressive symptoms. These factors were also associated with impairment in psychosocial functioning and quality of life related to depression.     

Prevalence and Correlates of Depressive Symptoms Following Traumatic Brain Injuries in Children

The prevalence and correlates of depressive symptoms following childhood traumatic brain injuries (TBI) were examined using data drawn from a prospective longitudinal study. Participants included 38 children with severe TBI, 51 with moderate TBI, and 55 with orthopedic injuries (OI). Assessments occurred shortly after injury (baseline) and at 6- and 12-month follow-ups. Children completed the Child Depression Inventory (CDI). Parents rated depressive symptoms using the Child Behavior Checklist (CBC), with baseline ratings reflecting premorbid status. Assessments also included measures of children's neurocognitive functioning and the family environment. The three groups did not differ overall in self-reported symptoms on the CDI, but did display different trends over time. The three groups did not differ on parent ratings of premorbid depressive symptoms on the CBC, but parents reported more depressive symptoms in the TBI groups than in the OI group at 6- and 12-month follow-ups. Child and parent reports were correlated for children in the TBI groups, but not for those in the OI group. Depressive symptoms were related to socioeconomic status in all groups. Socioeconomic status also was a significant moderator of group differences, such that the effects of TBI were exacerbated in children from more disadvantaged homes. Although self-reports of depressive symptoms were related inconsistently to children's verbal memory, parent reports of depressive symptoms were unrelated to IQ or verbal memory. The findings suggest that TBI increases the risk of depressive symptoms, especially among more socially disadvantaged children, and that depressive symptoms are not strongly related to post-injury neurocognitive deficits.

Co-occurrence of aggressive behavior and depressive symptoms in early adolescence: A longitudinal multi-informant study

IntroductionAggressive behavior and depressive symptoms co-occur frequently during adolescence. The failure model argues that the onset of aggressive behavior is more likely to precede the onset of depressive symptoms, whereas the acting-out model states that depressed mood predicts subsequent aggressive behavior. However, few longitudinal studies have examined with fully recursive models the temporal ordering of aggressive behavior and depressive symptoms during early adolescence.ObjectiveTherefore, this study examined the bidirectional associations between aggressive behavior and depressive symptoms during early adolescence, using a multi-informant cross-lagged panel model. Gender differences were also investigated.MethodWe used data from three waves of questionnaire data that were annually collected among 497 early adolescents (56.9% boys) and their parents, thereby covering an age range from 12 to 15. Adolescents reported on their depressive symptoms and the parents reported on the adolescents’ aggressive behavior.ResultsCross-lagged path analyses showed that early adolescents’ aggressive behavior predicted subsequent depressive symptoms, but early adolescents’ depressive symptoms did not predict aggressive behavior. Findings were similar for boys and girls.ConclusionThus, our results provide support for the failure model and suggest that reducing aggressive behavior at the start of adolescence might reduce the risk for subsequent depressive symptoms.     

African American children's reports of depressed mood, hopelessness, and suicidal ideation and later suicide attempts

This study attempted to assess whether family demographic characteristics and child aggressive behavior are equal to or better than child self-reported depressive symptoms in predicting suicidal behavior. Participants were a community population of African Americans first recruited at age 6 and followed periodically through age 19-20. Measures included child self-reports of depressed mood, hopelessness, and suicidal ideation, teacher reported child aggression in grades 4-6, 6 th grade caregiver report of family demographic characteristics, and the participants' report at age 19-20 of suicide attempts. Depressed mood proved the most consistent predictor of adolescent/young adult attempts in our logistic regression analyses of the data from the population as a whole and among females. The relationship between depressed mood and suicide attempts in males was in the expected direction, but was not statistically significant. Teacher-reported youth aggressive behavior did prove to be a significant predictor of attempts in 4 th and 5 th grade for the population as a whole, but not in our analyses by gender. The relationships between family demographic characteristics and attempts failed to reach statistical significance, but were, generally, in the expected direction. The study revealed that African American children's self-reports of depressed mood as early as grade 4 may prove useful in predicting adolescent/young adult suicide attempts, particularly among females. Neither family demographics nor teacher-reported child aggressive behavior proved equal to child self-reported depressive symptoms in predicting later suicide attempts.     

SCL--90--R Symptom Patterns for Adolescent Psychiatric Inpatients

We collected Symptom Check List-90-Revised (SCL-90-R) symptom pattern and severity data from a sample of 486 adolescent psychiatric inpatients. Preliminary comparison of these data with previously published data for adolescent nonpatients suggested no meaningful differences in overall symptom severity, although the data suggested higher Positive Symptom Distress index (PSDI) scores for inpatients, less severe somatization and psychoticism symptoms for inpatient males compared to nonpatient males, and more severe depressive symptoms for inpatient females compared to nonpatient females. Future studies should be directed toward farther analyses of such data and the development of representative and generalizable adolescent inpatient norms for the SCL-90-R.

The association between stress,self‐esteem and depressive symptoms in adolescents

This cross‐sectional study investigated gender and age differences on domains of stress, self‐esteem and depressive symptoms, as well as the association between those domains using a sample of Norwegian adolescents (N = 1,239). The data was analysed using Pearson product moment correlation, t‐tests, and hierarchical multiple regression analyses. The results showed significant differences between genders. Girls scored higher on five of seven stressor domains comprising peer pressure, home life, school attendance, school/leisure conflict and school performance as well as depression, while boys scored significantly higher on self‐esteem. The hierarchical multiple regression analysis showed that higher stress from school performance and school attendance related significantly to more depressive symptoms in both genders. Additionally, stress of home life significantly related to more depressive symptoms in girls, whereas stress of peer pressure was significant in association with depressive symptoms in boys. A strong, inverse association was found between self‐esteem and depression controlled for stress, especially in girls. Self‐esteem was not found to be a moderator of any stressor‐depression interactions. In conclusion, the results give support for the significant role of stress and self‐esteem on the experience of depressive symptoms in adolescents.     

Peer victimization and suicidal ideation: The role of gender and depression in a school-based sample

The current study investigated the relations among traditional and cyber victimization, depressive symptoms, suicidal ideation, and gender in a school-based sample of 403 9th grade (13 to 16-year-old) adolescents. Path analyses indicated that both traditional victimization and cyber victimization were associated with suicidal ideation indirectly through depressive symptoms. Although there was little evidence of gender differences in the associations among peer victimization and depressive symptoms and suicidal ideation, the relation between depressive symptoms and suicidal ideation was found to be significantly stronger for girls than boys. The current investigation confirms the complexity of the association between peer victimization and suicidal ideation and that depressive symptoms, as well as gender, may play a role in this complex relation. Future research should continue to explore the associations among victimization, depressive symptoms, and suicidal ideation within a social ecological framework.     

Personality antecedents of depressive tendencies in 18-year-olds: a prospective study

Antecedents of depressive tendencies at age 18 were longitudinally evaluated using data from nursery school through high school. Depression was measured by CES-D scores from which the contribution of self-reported anxiety was partialed. As early as age 7, boys who subsequently acknowledged dysthymia were aggressive, self-aggrandizing, and undercontrolled whereas girls with later depressive tendencies were intropunitive, oversocialized, and overcontrolling. Similar gender differences were observed in pre- and early adolescence. At age 14, dysthymic boys were more likely to use both marijuana and harder drugs whereas dysthymic girls showed no tendency to use marijuana but did show a marked tendency to experiment with hard drugs. These girls also displayed low self-esteem. Preschool IQ correlated positively with dysthymia in girls and negatively in boys. The psychodynamics of gender differences in depressive affect were discussed.
