Relations with parents and with peers, temperament, and trajectories of depressed mood during early adolescence

The Social Failure Model: Do Classroom Norms Play a Role in the Development of Antisocial Behavior and Depressive Symptoms?

This study examined the moderating role of descriptive and status norms in the stability of youth's antisocial behavior, and the link between initial antisocial behavior and the development of depressive symptoms over the course of one academic year, while controlling for initial depression levels. A total of 1081 students (51.06% girls; grades 4 through 6) in schools in low to average socio-economic status neighborhoods completed self-reports and a peer nomination inventory in the fall (T1) and spring (T2) of one year. Descriptive norms were operationalized as the classroom- and sex-specific mean level of antisocial behavior. Status norms were operationalized as the classroom- and sex-specific correlation between antisocial behavior and social preference. Descriptive norms moderated the link between T1 and T2 antisocial behavior, such that youth exhibiting high levels of antisocial behavior showed a greater increase in antisocial behavior in classrooms where descriptive norms strongly favored such behavior (i.e., + 1 SD) than in classrooms with neutral or weak descriptive norms (i.e., - 1 SD). Status norms moderated the association between T1 antisocial behavior and T2 depressive symptoms, such that youth with high levels of antisocial behavior had higher depressive symptoms in classrooms where status norms disfavored antisocial behavior than in classrooms with neutral or favorable norms. No moderating effects of sex or grade were observed. These results suggest that both descriptive norms and status norms play important, albeit distinct, roles in exacerbating youth's depressive symptoms and antisocial behavior, but they may also mitigate these same outcomes in favorable contexts.

The effects of childhood maltreatment, recent interpersonal and noninterpersonal stress, and HPA-axis multilocus genetic variation on prospective changes in adolescent depressive symptoms: A multiwave longitudinal study

Based on a multiwave, two-year prospective design, this study is the first to examine the extent to which multilocus hypothalamic-pituitary-adrenal axis (HPA axis)-related genetic variants, childhood maltreatment, and recent stress jointly predicted prospective changes in adolescent depressive symptoms. A theory-driven multilocus genetic profile score (MGPS) was calculated to combine the effects of six common polymorphisms within HPA-axis related genes (CRHR1, NR3C1, NR3C2, FKBP5, COMT, and HTR1A) in a sample of Chinese Han adolescents (N = 827; 50.2% boys; Mage = 16.45 ± 1.36 years). The results showed that the three-way interaction of HPA-axis related MGPS, childhood maltreatment and recent interpersonal, but not noninterpersonal, stress significantly predicted prospective changes in adolescent depressive symptoms. For adolescents with high but not low HPA-axis related MGPS, exposure to severe childhood maltreatment predisposed individuals more vulnerable to recent interpersonal stress, exhibiting greater prospective changes in adolescent depressive symptoms. The findings provide preliminary evidence for the cumulative risk mechanism regarding gene-by-environment-by-environment (G × E1 × E2) interactions that underlie the longitudinal development of adolescent depressive symptoms and show effects specific to interpersonal stress.

Self-regulation facets differentially predict internalizing symptom trajectories from middle childhood to early adolescence: a longitudinal multimethod study

BACKGROUND

Internalizing symptoms are among the most common psychological symptoms in childhood and adolescence, are highly stable and can cause severe impairment. Current research discusses lower capacities of self-regulation (SR) as risk factors for the development of internalizing symptoms. The present study identifies trajectories of internalizing symptoms in the transition phase from middle childhood to adolescence and examines multiple SR facets as predictors of potentially unfavorable trajectories, also in the presence of other established risk factors.

METHODS

The study utilized a community sample of N = 1453 (52.2% female) German children, who provided data at up to three measurement points (t1: 6-11 years, t2: 7-11 years, t3: 9-13 years). Trajectories of internalizing symptoms were based on parents' ratings of the emotional problems scale of the Strengths and Difficulties Questionnaire. SR facets were assessed using multiple methods and informants. Two multinomial regression analyses were conducted to predict class membership by (1) SR facets and gender and (2) SR facets, gender, and other established risk factors (education status, family adversity, peer problems).

RESULTS

Using growth mixture modelling, we identified three trajectory classes with stable low (n = 1200), increasing (n = 124), and early high decreasing internalizing symptoms (n = 129). In the regression analysis controlling for risk factors, membership in the increasing trajectory was significantly predicted by higher emotional reactivity (OR = 2.65, p < .001), higher cognitive flexibility/set-shifting (OR = 1.48, p = .032), and higher family adversity (OR = 1.38, p = .046). Membership in the early high decreasing trajectory was significantly predicted by higher emotional reactivity (OR = 4.15, p < .001), higher inhibitory control (OR = 1.47, p = .045), lower working-memory updating (OR = 0.69, p = .016), lower delay of gratification (OR = 0.75, p = .028), and higher family adversity (OR = 1.63, p = .001).

CONCLUSIONS

SR facets incrementally and differentially predict potentially unfavorable trajectories of internalizing symptoms from age 6 to 13, surpassing the predictive value of gender or education status. Higher emotional reactivity emerged as the most influential factor, which could therefore be addressed in future prevention and intervention efforts.

Personality-specific pathways from bullying victimization to adolescent alcohol use: a multilevel longitudinal moderated mediation analysis

Bullying victimization is common in adolescence and has been associated with a broad variety of psychopathology and alcohol use. The present study assessed time-varying associations between bullying victimization and alcohol use through internalizing and externalizing symptoms and whether this indirect association throughout time is moderated by personality. This 5-year longitudinal study (3,800 grade 7 adolescents) used Bayesian multilevel moderated mediation models: independent variable was bullying victimization; moderators were four personality dimensions (anxiety sensitivity, hopelessness, impulsivity, and sensation seeking); internalizing symptoms (anxiety, depressive symptoms) and externalizing symptoms (conduct, hyperactivity problems) were the mediators; and alcohol use, the outcome. Results indicated significant between, within, and lagged effects on alcohol use through internalizing and externalizing symptoms. There were significant between and within effects on alcohol use through internalizing symptoms for adolescents with high anxiety sensitivity and hopelessness, and significant between, within, and lagged effects on alcohol use through externalizing symptoms for adolescents with high impulsivity and sensation seeking. These findings implicate two risk pathways that account for how bullying victimization enhances alcohol use risk and emphasize the importance of personality profiles that can shape the immediate and long-term consequences of victimization.

Changes in Depression Among Adolescents: A Multiple-Group Latent Profile Transition Analysis

Background

Depression of adolescents is an important public health problem. Persistent depression will become a huge hidden danger of individual mental health development. It is important to study the change mechanism of adolescents' depression.

Methods

A total of 563 males and 739 females aged 11-19 years reported their depression. 1302 adolescents participated in a short-term 6-month longitudinal study. They were contacted every three months for two follow-up tests (T2 and T3). Participants completed internet addiction test, self-rating anxiety scale and self-rating depression scale. Multiple-group latent profile transition analysis (MLPTA) was used to identify meaningful subgroups and transitions between groups across time. Covariates (anxiety and internet addiction) were used to analyze the influencing factors.

Results

The results showed that: (1) There are three categories of adolescents' depression, namely no-depression group, low-depression-mountain group and low-depression-hill group. (2) The depression of the subjects showed a trend of improvement, but the proportion of low-depression-mountain group is relatively high at three time points (0.44, 0.59, and 0.30). (3) The transition probability between the low-depression-mountain group and the no-depression group is large, which suggests the low-depression-mountain group can easily convert into the no-depression group, but the transition probability from low-depression-hill group to other groups is relatively low and stable, which suggests the low-depression-hill group is not easily converted into the no-depression group. (4) Both anxiety and internet addiction affect the development of adolescents' depression across three time points. Anxiety played a significant role in affecting female adolescents' depression, while internet addiction played a significant role in affecting male adolescents' depression.

Conclusion

This study demonstrated a transition pattern in adolescents' depression. We should pay more attention to the low-depression-mountain group and try to do their mental health well. Adolescents' Depression changes rapidly with anxiety and internet addiction for different genders, which suggests that some interventions are needed.

Trajectories of temperament from late childhood through adolescence and associations with anxiety and depression in young adulthood

Anxiety and depression are pervasive and pernicious mental health problems for young adults. Developmental trajectories of adolescent temperament (Effortful Control, Negative Emotionality, and Positive Emotionality) may help us predict who will experience anxiety/depression during young adulthood. The present study used longitudinal data from a large, community sample of Mexican-origin youth ( N = 674) to examine how temperament develops across adolescence (age 10–16) and whether the developmental trajectories of temperament are associated with anxiety/depression during young adulthood (ages 19 and 21). Results indicate that Effortful Control, Negatively Emotionality, and the Affiliation facet of Positive Emotionality tend to decrease across adolescence, whereas Surgency tends to increase. Smaller decreases in Effortful Control and greater increases in Positive Emotionality across adolescence were associated with fewer anxiety/depression symptoms during young adulthood, whereas smaller decreases in Negative Emotionality were associated with more anxiety/depression symptoms later on. Thus, temperament development serves as both a protective factor (Effortful Control, Positive Emotionality) and a risk factor (Negative Emotionality) for later anxiety/depression in Mexican-origin youth.

Trajectories of Substance Use and Well-being in Early and Middle Adolescence Shaped by Social Connectedness

Increasing substance use and decreasing well-being are typical in adolescence, yet how social contexts shape disparate development during this time is less well-understood. A latent growth class analysis was conducted that identified groups of early (N = 706; Age_m  = 12.20) and middle (N = 666; Age_m  = 14.38) adolescents distinguished by rates of substance use and well-being over three years. In both cohorts, the largest group reported low substance use and high well-being, with a smaller group exhibiting maladaptive trajectories for both substance use and well-being. Two additional groups were identified during middle adolescence characterized by either low well-being or high substance use. Family connectedness was a protective factor, while high peer connectedness was a risk factor for substance-use groups and low peer connectedness for languishing.

Assessing Aspects of Social Relationships in Youth Across Middle Childhood and Adolescence: The NIH Toolbox Pediatric Social Relationship Scales

OBJECTIVE

Social relationships are a critical context for children's socioemotional development and their quality is closely linked with concurrent and future physical and emotional wellbeing. However, brief self-report measures of social relationship quality that translate across middle childhood, adolescence, and adulthood are lacking, limiting the ability to assess the impact of social relationships on health outcomes over time. To address this gap, this article describes the development and testing of the National Institutes of Health (NIH) Toolbox Pediatric Social Relationship Scales, which were developed in parallel with the previously-reported Adult Social Relationship Scales.

METHODS

Item sets were selected from the NIH Toolbox adult self-report item banks in the domains of social support, companionship, and social distress, and adapted for use in preadolescent (ages 8-11 years) and adolescent (ages 12-18 years) cohorts. Items were tested across a U.S. community sample of 1,038 youth ages 8-18 years. Classical test and item response theory approaches were used to identify items for inclusion in brief unidimensional scales. Concurrent validity was assessed by comparing resultant scales to established pediatric social relationship instruments.

RESULTS

Internal reliability and concurrent validity were established for five unique scales, with 5-7 items each: Emotional Support, Friendship, Loneliness, Perceived Rejection, and Perceived Hostility.

CONCLUSIONS

These brief scales represent developmentally appropriate and valid instruments for assessing the quality of youth social relationships across childhood and adolescence. In conjunction with previously published adult scales, they provide an opportunity for prospective assessment of social relationships across the developmental spectrum.

Negative emotionality and peer status: Evidence for bidirectional longitudinal influences during the elementary school years

Prior research indicates that high negative emotionality in combination with low peer status is conducive of clinically identified problems in childhood. This three-wave longitudinal study examined how negative emotionality and peer status are linked over time in middle and late childhood. Participants were recruited from second grade ( n = 90, mean age = 8.85) and fourth grade ( n = 119, mean age = 10.81) and were followed across a period of 2 years. Cross-lagged structural models examining concurrent and longitudinal associations between teacher-reported negative emotionality and peer ratings of likability were analyzed separately for externalizing emotion (anger) and internalizing emotion (sadness and fear). Both analyses provided support for a conceptual model in which high negative emotionality lowers peer status, and low peer status, in turn, through a feedback loop, increases negative emotionality over time. Bidirectional influences are interpreted as reflecting a transactional process involving the effects of negative emotionality on social behavior. The findings highlight the need for active efforts to help children with high negative emotionality gain acceptance from classmates.

The Longitudinal Interplay Between Social Network and Psychopathology in Multi-Problem Young Adult Men; Separating Within-and Between-Person Effects

Young adulthood is characterized by many life changes. Especially for young men with problems across different life domains (i.e., multi-problem), these changes may entail obstacles. Incidences of psychopathology increase during young adulthood and at the same time important shifts in social networks - such as changing relations with peers and parents, isolation, or deviant peer affiliation - take place. The present study examined the longitudinal interplay between psychopathology and social network characteristics over the course of 1 year in multi-problem young adults, at both between-person and within-person level. A sample of 696 multi-problem young adult men (age 18-27) participated in this three wave study. We used traditional cross-lagged panel models (CLPM) to examine how social network characteristics and psychopathology are related at the between-person level, and random intercept cross-lagged panel models (RI-CLPM) to examine within-person links. Between-person associations between internalizing problems and social networks were bidirectional, and externalizing problems were related to problematic social network characteristics, but not vice versa. At the within-person level, no such cross-lagged paths were found. Overall, results indicated that in multi-problem young adults, social network characteristics and psychopathology are related. However, looking at within-person processes this relation is not reciprocal.

Basic epidemiology of wellbeing among children and adolescents: A cross-sectional population level study

Wellbeing and mental health are fundamental rights of children and adolescents essential for sustainable development. Understanding the epidemiology of child and adolescent wellbeing is essential to informing population health approaches to improving wellbeing and preventing mental illness. The present study estimated the prevalence of wellbeing and how wellbeing indicators were distributed across social and economic groups. This study used data from the 2019 Wellbeing and Engagement Collection; an annual census conducted in South Australian schools that measures self-reported wellbeing in students aged 8–18 years (n = 75,966). We estimated the prevalence (n, %) of low, medium and high wellbeing across five outcomes: life satisfaction, optimism, sadness, worries and happiness, overall and stratified by gender, age, language background, socio-economic position and geographical remoteness. The prevalence of low wellbeing on each indicator was: happiness 13%, optimism 16%, life satisfaction 22%, sadness 16% and worries 25%. The prevalence of low wellbeing increased with age, particularly for females. For example, 22.5% of females aged 8–10 years had high levels of worries compared to 43.6% of 15 to 18-year old females. Socioeconomic inequality in wellbeing was evident on all indicators, with 19.5% of children in the most disadvantaged communities having high levels of sadness compared to 12.5% of children in the most advantaged communities. Many children and adolescents experience low wellbeing on one or more indicators (40.7%). The scale of this problem warrants a population-level preventative health response, in addition to a clinical, individual-level responses to acute mental health needs. Universal school-based programs that support social and emotional wellbeing have a role to play in this response but need to be supported by universal and targeted responses from outside of the education system.

•

Many children and adolescents experience low wellbeing during their schooling years.

•

Wellbeing declines with age and adolescent females are at a particularly high risk of low wellbeing.

•

Children living in more disadvantaged communities have poorer wellbeing than their peers living in more affluent communities.

Psychosocial Adjustment and Sociometric Status in Primary Education: Gender Differences

The acceptance or rejection of classmates is one of the most widely recognized determinants of wellbeing in childhood. This study analyses psychosocial adjustment and sociometric status in primary education pupils, and possible differences by gender. A cross-sectional survey was undertaken in Huelva (Spain). The surveyed schools were selected using a stratified random sampling technique with both public and private elementary schools. Sample was composed of 247 4th grade students. Data revealed gender differences in psychosocial adjustment, particularly in terms of prosocial behavior in girls and behavioral problems in boys. Popular and rejected statuses presented opposing adjustment profiles, particularly in hyperactive symptoms and behavioral problems. When the sample was separated by gender, the differences between the types of status in emotional symptomatology and prosocial behavior disappeared. In addition, the differences between statuses were greater in boys, and were defined mainly by hyperactivity, whilst for girls these differences were more apparent in behavioral problems.

Trajectories of Depressive Symptoms Among North American Indigenous Adolescents: Considering Predictors and Outcomes

We identified developmental trajectories of depressive symptoms among 674 Indigenous adolescents (Mage  = 11.10, SD = 0.83 years) progressing from early to late adolescence. Four depressive symptoms trajectories were identified: (a) sustained low, (b) initially low but increasing, (c) initially high but decreasing, and (d) sustained high levels of depressive symptoms. Trajectory group membership varied as a function of gender, pubertal development, caregiver major depression, and perceived discrimination. Moreover, participants in the different trajectory groups were at differential risk for the development of an alcohol use disorder. These results highlight the benefit of examining the development of depressive symptoms and the unique ways that depressive symptoms develop among North American Indigenous youth as they progress through adolescence.

Gender differences in trajectories of depressive symptoms across childhood and adolescence: A multi-group growth mixture model

BACKGROUND

This study sought to identify depression trajectories across childhood and to model a range of child and family predictors of whether a child may be on an increasing trajectory towards depressive disorder in adolescence.

METHODS

Multi-group growth mixture modelling (MGMM) was used on a sample of 4983 children from the Longitudinal Study of Australia Children (LSAC). Depressive symptoms of these children were assessed over 10-years with six time-points, administered every second year commencing at 4 years via the parent report version of the Strength and Difficulties Questionnaire. Predictors of class membership were also examined.

RESULTS

Four trajectories were found to be the best fitting model characterising low-stable (75%); decreasing (11%); increasing (9%); high and rising (6%) groups. Females were more likely to be in a trajectory of increasing depressive symptoms between 4 and 14 years of age than males. Reactive temperament and maternal depression at four and six years of age were consistent predictors of increasing and high trajectories while persistent temperament acts as a protective factor for females.

LIMITATIONS

The findings should be interpreted in the light of limitations due to common-method variance and the absence of diagnostic indicators of depressive disorder.

CONCLUSIONS

We conclude that there are gender differences in patterns of depressive symptoms from childhood to adolescence and meaningful predictors of these early developmental trajectories. Preventative interventions in childhood targeting parents with depression and children with temperamental difficulties may be indicated.

The Family Check Up and Adolescent Depression: An Examination of Treatment Responders and Non-Responders

The Family Check Up (FCU) is a family-centered intervention for reducing children's problem behavior through improving parenting skills and family interactions. Although the FCU was designed to prevent conduct problems, we have also found the program to be effective in preventing escalating symptoms of depression in early adolescence. The current analyses examine heterogeneous patterns of response to treatment in an effort to identify factors associated with differential response to family intervention. We examined heterogeneity in trajectories of youth-reported depressive symptoms from grades 6 to 9, using a Latent Growth Mixture Modeling framework to identify patterns of treatment response and non-response. Three symptom trajectories were identified, including the following: (1) a large class exhibiting stable, low symptom levels, (2) a class exhibiting high and stable depressive symptoms, and (3) a class exhibiting low initial symptoms that increased over time. Significant intervention effects were identified only among the third class, as a preventive effect on depression from 7th to 9th grade for youth with low initial symptoms. No effect of intervention was observed in the other two classes. Comparisons of classes 2 and 3 suggested that class 3 members were more likely to be females with high baseline antisocial behavior, but lower initial levels of depression. The findings suggest the importance of exploring heterogeneity within a prevention design, as well as the importance of tailored approaches to the prevention of adolescent depression.

Identifying Critical Points of Trajectories of Depressive Symptoms from Childhood to Young Adulthood

Depression is a common mental illness and research has focused on late childhood and adolescence in an attempt to prevent or reduce later psychopathology and/or social impairments. It is important to establish and study population-averaged trajectories of depressive symptoms across adolescence as this could characterise specific changes in populations and help identify critical points to intervene with treatment. Multilevel growth-curve models were used to explore adolescent trajectories of depressive symptoms in 9301 individuals (57% female) from the Avon Longitudinal Study of Parents and Children, a UK based pregnancy cohort. Trajectories of depressive symptoms were constructed for males and females using the short mood and feelings questionnaire over 8 occasions, between 10 and 22 years old. Critical points of development such as age of peak velocity for depressive symptoms (the age at which depressive symptoms increase most rapidly) and the age of maximum depressive symptoms were also derived. The results suggested that from similar initial levels of depressive symptoms at age 11, females on average experienced steeper increases in depressive symptoms than males over their teenage and adolescent years until around the age of 20 when levels of depressive symptoms plateaued and started to decrease for both sexes. Females on average also had an earlier age of peak velocity of depressive symptoms that occurred at 13.5 years, compared to males who on average had an age of peak velocity at 16 years old. Evidence was less clear for a difference between the ages of maximum depressive symptoms which were on average 19.6 years for females and 20.4 for males. Identifying critical periods for different population subgroups may provide useful knowledge for treating and preventing depression and could be tailored to be time specific for certain groups. Possible explanations and recommendations are discussed.

Depressive Symptom Trajectories Among Sexually Abused Youth: Examining the Effects of Parental Perpetration and Age of Abuse Onset

Researchers found that sexual abuse in childhood leads to increased adolescent depressive symptomatology, though this link may vary due to the relationship between the victim and the perpetrator as well as the age of the child when the abuse began. A sample of 444 sexually abused youth provided data for the National Survey of Child and Adolescent Well-Being I. Growth mixture modeling was used to identify trajectories of depressive symptoms and test the effects of parental perpetration and age of abuse onset. Results supported the following three growth trajectories of depressive symptoms in adolescence: falling, rising, and flat. Youth who were sexually abused by a parent were more likely to follow the rising and falling trajectories. Also, youth who experienced sexual abuse at a younger age were more likely to be classified in the falling trajectory. Findings can inform intervention programming on the links between sexual abuse characteristics and subsequent patterns of adolescent depressive symptomology.

Is It Enough to Be an Extrovert to Be Liked? Emotional Competence Moderates the Relationship Between Extraversion and Peer-Rated Likeability

Likeability represents one of the aspects of social status in a peer group and refers to the extent to which one is accepted, preferred by others, and perceived as a likeable companion. Previous research has demonstrated that likeability is partly determined by dispositional factors. One body of research shows that variance in likeability across individuals can be traced to personality traits, mainly extraversion and agreeableness. Another expanding body of research demonstrates that success in achieving peer acceptance is determined, in some part, by the emotional competencies (ECs) of an individual. In an attempt to combine these two approaches and to clarify some inconsistencies in the results concerning the personality–likeability relationships, this study was designed to examine the interactive effect of adolescents’ personality traits (i.e., extraversion and agreeableness) and ECs on peer-rated likeability in adolescence. A sample of 230 adolescents (47% female) from two comprehensive secondary schools in Poland completed measures of personality traits and ECs, as well as a sociometric assessment of likeability in their classrooms. The results demonstrated that interpersonal EC acts as a moderator in the relationship between extraversion and peer-rated likeability. Specifically, extraversion predicted greater likeability among adolescents with high interpersonal EC but not among adolescents with low interpersonal EC. The study yielded new insights into the determinants of likeability, as it demonstrates that adolescents need to be both extrovert and possess high interpersonal EC in order to be judged highly likeable by their peers. It also bears practical implications for the improvement of adolescents’ position and acceptance within their peer group. The results suggest that encouraging “rejected” adolescents to reach out to others in an extrovert fashion is necessary but insufficient to increase their likeability. Improving their interpersonal EC is also necessary. The observation that higher levels of interpersonal EC helps adolescents to achieve higher acceptance in their peer group suggests the need to implement school training programs aimed at improving the core ECs (identification, understanding, expression, regulation and use of emotions).

Review: Longitudinal trajectories of child and adolescent depressive symptoms and their predictors - a systematic review and meta-analysis

BACKGROUND

With depression predicted to contribute to an increased disease burden in coming decades, prevention efforts have become increasingly important. In order to prevent depression it is valuable to identify and classify longitudinal patterns of depressive symptoms across development, ideally beginning early in childhood. To achieve this, longitudinal studies are increasingly using person-centered data-analytic methods to model subgroups with similar developmental patterns (trajectories) of depressive symptoms.

METHOD

A search was completed for English language studies that longitudinally modeled depressive symptom trajectories in nonclinical populations with a baseline age of <19 years. Study characteristics were extracted, prevalence rates and risk factors were summarized, a random-effect meta-analysis was undertaken, and risk of bias analysis completed.

RESULTS

Twenty studies published between 2002 and 2015 were included. Participants were recruited at ages 4 through 17 (average age 12.34) and followed longitudinally for an average of 7.45 years. Between 3 and 11 trajectory subgroups were identified. A random pooled effect estimate identified 56% [95% Confidence Interval (CI) 46-65%] of the sampled study populations (N = 41,236) on 'No or low' depressive symptom trajectories and 26% (CI 14-40%) on a 'Moderate' trajectory. 'High', 'Increasing', and 'Decreasing' depressive symptom subgroups were evident for 12% (CI 8-17%). Moderate symptoms were associated with poorer adjustment and outcomes relative to low symptom groups. 'High' or 'Increasing' trajectories were predominantly predicted by: female gender, low socioeconomic status, higher stress reactivity; conduct issues; substance misuse, and problems in peer and parental relationships.

CONCLUSIONS

The review highlighted consistent evidence of subgroups of children and adolescents who differ in their depressive symptom development over time. The findings suggest preventative interventions should evaluate the longer term benefits of increasing membership in low and moderate trajectories, while also targeting reductions in high-risk subgroups. Considerable between-study method and measurement variation indicate the need for future trajectory studies to use standardized methods.

Transitions of Developmental Trajectories of Depressive Symptoms Between Junior and Senior High School Among Youths in Taiwan: Linkages to Symptoms in Young Adulthood

We investigated the heterogeneous developmental trajectories of depressive symptoms in junior and senior high school, the transitions to different trajectories after entering senior high school, and the linkages to the development of depressive symptoms in early adulthood among Taiwanese adolescents. An eight-wave longitudinal data set was analyzed, including 2687 Taiwanese adolescents (51.2% boys, M age = 14.3 at first wave). Using a manual three-step latent transition growth mixture model, we found that a three-class solution fit the data for both junior high school (termed high-improving, cumulative, and JS-low-stable) and senior high school period (termed heightening, moderate-stable, and HS-low-stable). The depressive symptoms of most individuals maintained at a low level (i.e., low-stable) from adolescence to early adulthood; however, nearly a quarter of the adolescents reported depressive symptoms that were moderately or highly severe in senior high school and beyond. More than 30% of the participants experienced transitioning into a different developmental trajectory between junior and senior high school. When perceiving a higher level of paternal behavioral control, adolescents categorized in the high-improving class in junior high school would have a higher chance to transition to the moderate-stable class than to HS-low-stable class in senior high school. Adolescent boys and girls did not differ in the probability of transitioning between trajectories across junior and senior high school. However, a clear and consistent pattern of symptoms between late adolescence and early adulthood was not observed. These results help elucidate the heterogeneity and fluidity associated with the development of depressive symptoms between early adolescence and early adulthood in light of school transition among youths in Taiwan.

Co-development of Problem Gambling and Depression Symptoms in Emerging Adults: A Parallel-Process Latent Class Growth Model

This study examines whether there are multiple joint trajectories of depression and problem gambling co-development in a sample of emerging adults. Data were from the Manitoba Longitudinal Study of Young Adults (n = 679), which was collected in 4 waves across 5 years (age 18-20 at baseline). Parallel process latent class growth modeling was used to identified 5 joint trajectory classes: low decreasing gambling, low increasing depression (81%); low stable gambling, moderate decreasing depression (9%); low stable gambling, high decreasing depression (5%); low stable gambling, moderate stable depression (3%); moderate stable problem gambling, no depression (2%). There was no evidence of reciprocal growth in problem gambling and depression in any of the joint classes. Multinomial logistic regression analyses of baseline risk and protective factors found that only neuroticism, escape-avoidance coping, and perceived level of family social support were significant predictors of joint trajectory class membership. Consistent with the pathways model framework, we observed that individuals in the problem gambling only class were more likely using gambling as a stable way to cope with negative emotions. Similarly, high levels of neuroticism and low levels of family support were associated with increased odds of being in a class with moderate to high levels of depressive symptoms (but low gambling problems). The results suggest that interventions for problem gambling and/or depression need to focus on promoting more adaptive coping skills among more "at-risk" young adults, and such interventions should be tailored in relation to specific subtypes of comorbid mental illness.

Trajectories of emotional symptoms in adolescence: impact on alcohol use

Purpose

The purpose of this paper is to explore how different trajectories of emotional symptoms relate to alcohol use in adolescence.

Design/methodology/approach

In all, 431 participants (majority female), aged approximately 13 years at baseline were followed over three years and reported on their emotional symptoms and alcohol use. Latent class growth analyses explored different trajectories of emotional symptoms and regression models were run to relate these trajectories to alcohol use (full standard drink, and binge drinking) at 36-month follow-up (age 16 years).

Findings

While the majority of adolescents were best characterised by low-stable emotional symptoms, those with high-stable symptoms were more likely to be have consumed a full standard drink of alcohol and binge drunk when aged 16 years.

Research limitations/implications

Findings highlight the importance of prevention and early intervention, particularly targeting adolescents with elevated stable emotional symptoms who were more likely to be using alcohol at 16 years of age.

Originality/value

The present study is one of the first longitudinal investigations into the use of alcohol by community adolescents with different emotional symptom trajectories.

Longitudinal Trajectories of Depression Symptoms in Adolescence: Psychosocial Risk Factors and Outcomes

Variations in symptom trajectories within a population may represent distinct groups with different etiologies and outcomes. This study aimed to identify subgroups of depression symptom trajectories in a sample of adolescents, and to describe psychosocial attributes of the different groups. In a longitudinal study, 243 adolescents (121 males and 122 females), were assessed using a battery of measures of temperament, psychopathology, and psychological and behavioral functioning. Four phases of data collection over 7 years spanned average ages of the participants from 12 to 18 years old. Depressive symptoms from each phase were used to model latent class growth trajectories. A 4-group solution was selected as the best-fitting model: (1) ongoing stable low levels of depression; (2) very high depressive symptoms initially, but a steep decrease in symptoms over time; (3) moderately high depressive symptoms initially, but symptoms decreased over time; and (4) initially low levels of symptoms that increased over time. Trajectory group membership was associated with a range of psychosocial variables including temperament, childhood maltreatment, and young adult quality of life. Characterising these subgroups allows for a better understanding of how the interaction of risk factors increases the likelihood of depression and other poor outcomes, and highlights the importance of early interventions to prevent and treat adolescent depression.

Brain Structural Signatures of Adolescent Depressive Symptom Trajectories: A Longitudinal Magnetic Resonance Imaging Study

OBJECTIVE

Most evidence for structural brain abnormalities associated with adolescent depression is based on cross-sectional study designs that do not take into account the dynamic course of depressive symptoms and brain maturation across adolescence. In this study, a longitudinal design was used to investigate the association between different trajectories of depressive symptoms and longitudinal changes in brain structure throughout adolescence.

METHOD

One hundred forty-nine adolescents were assessed on depressive symptoms and underwent structural magnetic resonance imaging at 12 years of age and were followed up multiple times until 19 years. Three depressive symptom trajectories (low-stable [n = 97], early-decreasing [n = 33], late-increasing [n = 19]) were identified, and effects of group and group by time on hippocampus and amygdala volume and prefrontal cortical thickness and surface area were evaluated.

RESULTS

The early-decreasing symptoms group exhibited differences in cortical surface area compared to the low-stable and late-increasing symptoms groups, moderated by sex. Specifically, females in the early-decreasing symptoms group showed lower anterior cingulate and orbitofrontal cortex surface areas across adolescence compared to females in the other groups. Males in the early-decreasing symptoms group showed lower right orbitofrontal cortex surface area expansion over time compared to males in the low-stable and late-increasing symptoms groups. No effects were found for cortical thickness or for hippocampus and amygdala volume.

CONCLUSION

Alterations in cortical surface area were specifically observed in young people experiencing depressive symptoms in early adolescence. These findings suggest that early adolescence is a particularly sensitive period for cortical surface area abnormalities associated with depressive symptoms and could provide a critical window for treatment of (subthreshold) depressive symptoms.

Childhood conduct problems and young adult outcomes among women with childhood attention-deficit/hyperactivity disorder (ADHD)

We tested whether conduct problems predicted young adult functioning and psychiatric symptoms among women diagnosed with attention-deficit/hyperactivity disorder (ADHD) during childhood, in the context of 3 potential adolescent mediators: internalizing problems, peer rejection, and school failure and disciplinary problems. We controlled for childhood ADHD severity, IQ, and demographic factors, and in the mediational tests, for adolescent conduct problems. Data came from 140 participants in the Berkeley Girls With ADHD Longitudinal Study. We used bootstrapping methods to assess indirect effects (mediators). Both childhood, F(1, 118) change = 9.00, p = .003, R2 change = .069, and adolescent, F(1, 109) change = 10.41, p = .002, R2 change = .083, conduct problems were associated with worse overall functioning during young adulthood, controlling for initial ADHD severity, child IQ, and demographics. Results were similar when predicting psychiatric symptoms. Adolescent school failure and disciplinary problems mediated the relations between childhood conduct problems and both young adult functioning and externalizing problems; adolescent internalizing problems and peer conflict mediated the relation between childhood conduct problems and young adult internalizing problems. As is true for boys, childhood and adolescent conduct problems are associated with poor adult outcomes among girls with ADHD, with school failure and disciplinary problems, internalizing problems, and peer conflict functioning as mediators of these relations.

The role of bullying in depressive symptoms from adolescence to emerging adulthood: A growth mixture model

BACKGROUND

The present study sought to identify trajectories of depressive symptoms in adolescence and emerging adulthood using a school-based sample of adolescents assessed over a five-year period. The study also examined whether bully and cyberbully victimization and perpetration significantly predicted depressive symptom trajectories.

METHOD

Data from a sample of 1042 high school students were examined. The sample had a mean age of 15.09 years (SD=.79), was 56.0% female, and was racially diverse: 31.4% Hispanic, 29.4% White, and 27.9% African American. Data were examined using growth mixture modeling.

RESULTS

Four depressive symptoms trajectories were identified, including those with a mild trajectory of depressive symptoms, an increasing trajectory of depressive symptoms, an elevated trajectory of depressive symptoms, and a decreasing trajectory of depressive symptoms. Results indicated that bully victimization and cyberbully victimization differentially predicted depressive symptoms trajectories across adolescence, though bully and cyberbully perpetration did not.

LIMITATIONS

Limitations include reliance on self-reports of bully perpetration and a limited consideration of external factors that may impact the course of depression.

CONCLUSIONS

These findings may inform school personnel in identifying students' likely trajectory of depressive symptoms and determining where depression prevention and treatment services may be needed.

A powerful phenotype for gene-finding studies derived from trajectory analyses of symptoms of anxiety and depression between age seven and 18

To investigate the utility of longitudinal data in genetic analyses of symptoms of anxiety and depression, we assessed individual differences between age 7 and 18 using growth mixture models, and investigated the genetic and non-genetic factors contributing to the trajectories. Mothers of 7,706 girl and 7,418 boy twins from the Netherlands Twin Register rated the anxious depression scale (SxAnxDep) of the Child Behavior Check List (CBCL) at age 7, 10, and 12 years. Two thousand seven hundred and six girl and 1,856 boy twins completed the Youth Self Report (YSR) at age 14, 16, and 18. While individual trajectories varied considerably, these differences were largely idiosyncratic and could not be grouped into separate latent classes with class-specific average growth curves. The intercept, which reflects the individuals' baseline level of SxAnxDep across time, explained 55-58% of the total phenotypic variance. The slope factor, which captures a common average trend over time, did not explain variance in the phenotype. This finding also underlines the high level of idiosyncrasy of trajectories that lack a common longitudinal structure. The analyses of twin data showed that the random intercept factor of SxAnxDep during childhood and during adolescence is considerably more heritable than the observations at any single age, namely between 60% and 84%. One explanation is that different factors contribute to the level of symptoms of anxiety and depression at any given time point, including temporary events and emotions. When considering baseline stability, these temporary influences average out, with the result of a more reliable and more heritable phenotype. © 2015 Wiley Periodicals, Inc.

Stressful Life Events During Pregnancy and Offspring Depression: Evidence From a Prospective Cohort Study

OBJECTIVE

The fetal programming hypothesis posits that in utero exposure to stress can alter prenatal brain development and lifelong stress response. However, human studies linking objective prenatal stressors to offspring mental illness, especially depression, are rare. The purpose of this study was to examine the association between mothers' exposure to prenatal stressful life events (SLEs) and offspring depression.

METHOD

The sample comprised 10,569 members of a prospective population-based cohort, the Avon Longitudinal Study of Parents and Children (ALSPAC). Mothers reported on the occurrence and impact of 42 prenatal SLEs. Offspring depressive symptoms were assessed using a computerized version of the Clinical Interview Schedule-Revised (CIS-R) at age 17 to 18, as well as 13 self-report statements from the Short Mood and Feelings Questionnaire (SMFQ) at 6 time points from ages 10 to 11 to 18 to 19. Latent class growth analysis (LCGA) was used to identify trajectories of depressive symptoms across adolescence.

RESULTS

After adjusting for potential confounders, a 1-unit increase in maternal SLE scores (range, 0-168) during gestation was associated with increased offspring depressive symptoms (β = 0.07, p < .01) and major depression (odds ratio [OR] = 1.03, 95% CI 1.01, 1.06) at age 17 to 18. LCGA revealed 4 trajectories of depressive symptoms. High maternal SLEs (fourth quartile) were associated with membership in the trajectory characterized by stable, high levels of depression from age 10 to 11 to 18 to 19 years (OR = 1.72, 95% CI = 1.09, 2.71).

CONCLUSION

These results provide support for the fetal programming hypothesis, demonstrating that prenatal exposure to acute stress is associated with offspring depression in adolescence. Stress management may be of benefit for expectant mothers.

The Developmental Trajectories of Depressive Symptoms in Early Adolescence: An Examination of School-Related Factors

This study investigated the heterogeneity of depressive symptom trajectories and the roles of school-related factors in predicting the membership of different trajectories in a sample of early adolescents in Taiwan. In all, 870 junior high school students were followed for 3 years. Using growth mixture modeling, the study identified four distinct trajectories: stable-low depression, stable-moderate depression, steadily increasing depression, and early elevated but later decreasing depression. Female and private school students tended to belong to the high-risk group. Students with negative academic self-concept, low self-esteem, or poor peer relationships tended to follow the two high-risk trajectories (stable-moderate depression and steadily increasing depression). The findings suggested that these school-related factors could be used to target the high-risk depressive symptom groups for receiving further counseling, especially in the East Asian context.

Latent class profiles of depressive symptoms from early to middle childhood: predictors, outcomes, and gender effects

BACKGROUND

There has been little available data to inform the predictors and outcomes of latent class trajectories of depressive symptoms beginning during preschool and continuing throughout school age. Further, the extant literature in this domain has been limited by the use of parent report checklists of nonspecific 'internalizing' psychopathology rather than diagnostic interviews for depression.

METHODS

To address these gaps in the literature, this study applied growth mixture modeling to depressive symptom severity endorsed by children and/or their caregivers (N = 348) during a structured clinical interview in a 10-year longitudinal dataset spanning from preschool into late school age.

RESULTS

Three distinct trajectories of depressive symptom severity were found in boys and girls. For boys, but not girls, the high depression severity latent class increased in depressive symptoms from preschool through school age, followed by a decline in depressive symptom severity during later school age. For girls, the high depression severity latent class remained stable across time. Early childhood social adversity, familial history of affective disorder, preschool-onset ODD/CD, and school age functional impairment differentiated high-risk trajectory classes among both boys and girls.

CONCLUSIONS

Extending the literature on trajectories of depressive symptoms to the preschool period, these findings incorporate structured clinical interviews of depressive symptom severity and indicate gender differences as well as psychosocial predictors and functional outcomes among children in high severity latent classes. The findings from this study suggest that increased attention to screening for depressive symptoms in early childhood is of significant public health importance.

GROUP-BASED SYMPTOM TRAJECTORIES IN INDICATED PREVENTION OF ADOLESCENT DEPRESSION

BACKGROUND

Adolescent depression prevention research has focused on mean intervention outcomes, but has not considered heterogeneity in symptom course. Here, we empirically identify subgroups with distinct trajectories of depressive symptom change among adolescents enrolled in two indicated depression prevention trials and examine how cognitive-behavioral (CB) interventions and baseline predictors relate to trajectory membership.

METHODS

Six hundred thirty-one participants were assigned to one of three conditions: CB group intervention, CB bibliotherapy, and brochure control. We used group-based trajectory modeling to identify trajectories of depressive symptoms from pretest to 2-year follow-up. We examined associations between class membership and conditions using chi-square tests and baseline predictors using multinomial regressions.

RESULTS

We identified four trajectories in the full sample. Qualitatively similar trajectories were found in each condition separately. Two trajectories of positive symptom course (low-declining, high-declining) had declining symptoms and were distinguished by baseline symptom severity. Two trajectories of negative course (high-persistent, resurging), respectively, showed no decline in symptoms or decline followed by symptom reappearance. Participants in the brochure control condition were significantly more likely to populate the high-persistent trajectory relative to either CB condition and were significantly less likely to populate the low-declining trajectory relative to CB group. Several baseline factors predicted trajectory classes, but gender was the most informative prognostic factor, with males having increased odds of membership in a high-persistent trajectory relative to other trajectories.

CONCLUSIONS

Findings suggest that CB preventive interventions do not alter the nature of trajectories, but reduce the risk that adolescents follow a trajectory of chronically elevated symptoms.

A Randomized Depression Prevention Trial Comparing Interpersonal Psychotherapy--Adolescent Skills Training to Group Counseling in Schools

Given the rise in depression disorders in adolescence, it is important to develop and study depression prevention programs for this age group. The current study examined the efficacy of Interpersonal Psychotherapy-Adolescent Skills Training (IPT-AST), a group prevention program for adolescent depression, in comparison to group programs that are typically delivered in school settings. In this indicated prevention trial, 186 adolescents with elevated depression symptoms were randomized to receive IPT-AST delivered by research staff or group counseling (GC) delivered by school counselors. Hierarchical linear modeling examined differences in rates of change in depressive symptoms and overall functioning from baseline to the 6-month follow-up assessment. Cox regression compared rates of depression diagnoses. Adolescents in IPT-AST showed significantly greater improvements in self-reported depressive symptoms and evaluator-rated overall functioning than GC adolescents from baseline to the 6-month follow-up. However, there were no significant differences between the two conditions in onset of depression diagnoses. Although both intervention conditions demonstrated significant improvements in depressive symptoms and overall functioning, results indicate that IPT-AST has modest benefits over groups run by school counselors which were matched on frequency and duration of sessions. In particular, IPT-AST outperformed GC in reduction of depressive symptoms and improvements in overall functioning. These findings point to the clinical utility of this depression prevention program, at least in the short-term. Additional follow-up is needed to determine the long-term effects of IPT-AST, relative to GC, particularly in preventing depression onset.

Trajectory Pathways for Depressive Symptoms and Their Associated Factors in a Chinese Primary Care Cohort by Growth Mixture Modelling

Background

The naturalistic course for patients suffering from depressive disorders can be quite varied. Whilst some remit with little or no intervention, others may suffer a more prolonged course of symptoms. The aim of this study was to identify trajectory patterns for depressive symptoms in a Chinese primary care cohort and their associated factors.

Methods and Results

A 12-month cohort study was conducted. Patients recruited from 59 primary care clinics across Hong Kong were screened for depressive symptoms using the Centre for Epidemiologic Studies Depression Scale (CES-D) and monitored over 12 months using the Patient Health Questionnaire-9 items (PHQ-9) administered at 12, 26 and 52 weeks. 721 subjects were included for growth mixture modelling analysis. Using Akaike Information Criterion, Bayesian Information Criterion, Entropy and Lo-Mendell-Rubin adjusted likelihood ratio test, a seven-class trajectory path model was identified. Over 12 months, three trajectory groups showed improvement in depressive symptoms, three remained static, whilst one deteriorated. A mild severity of depressive symptoms with gradual improvement was the most prevalent trajectory identified. Multivariate, multinomial regression analysis was used to identify factors associated with each trajectory. Risk factors associated with chronicity included: female gender; not married; not in active employment; presence of multiple chronic disease co-morbidities; poor self-rated general health; and infrequent health service use.

Conclusions

Whilst many primary care patients may initially present with a similar severity of depressive symptoms, their course over 12 months can be quite heterogeneous. Although most primary care patients improve naturalistically over 12 months, many do not remit and it is important for doctors to be able to identify those who are at risk of chronicity. Regular follow-up and greater treatment attention is recommended for patients at risk of chronicity.

Adolescent Trajectories of Depressive Symptoms: Codevelopment of Behavioral and Academic Problems

PURPOSE

Increasing evidence suggests the existence of heterogeneity in the development of depressive symptoms during adolescence, but little remains known regarding the implications of this heterogeneity for the development of commonly co-occurring problems. In this study, we derived trajectories of depressive symptoms in adolescents and examined the codevelopment of multiple behavioral and academic problems in these trajectories.

METHODS

Participants were 6,910 students from secondary schools primarily located in disadvantaged areas of Quebec (Canada) who were assessed annually from the age 12 to 16 years. Trajectories were identified using growth mixture modeling. The course of behavioral (delinquency, substance use) and academic adjustment (school liking, academic achievement) in trajectories was examined by deriving latent growth curves for each covariate conditional on trajectory membership.

RESULTS

We identified five trajectories of stable-low (68.1%), increasing (12.1%), decreasing (8.7%), transient (8.7%), and stable-high (2.4%) depressive symptoms. Examination of conditional latent growth curves revealed that the course of behavioral and academic problems closely mirrored the course of depressive symptoms in each trajectory.

CONCLUSIONS

This pattern of results suggests that the course of depressive symptoms and other adjustment problems over time is likely to involve an important contribution of shared underlying developmental process(es).

Parental and individual predictors of trajectories of depressive symptoms in Chilean adolescents

Depressive symptoms are prevalent in adolescence, but not all adolescents experience the same level or evolution of symptoms, suggesting the need to identify differences in trajectories of symptoms. We used Growth Mixture Modeling to analyze different trajectories of depressive symptoms in a sample of 1,072 Chilean adolescents (12-15 years old, 54% female). First, a baseline model was selected and then adolescent irritability, maternal warmth, demandingness and disrespect were introduced to the model as predictors of class membership. Four latent class trajectories of depressive symptoms were identified: high persistent (12%), low stable (56%), high decreasing (15%) and low increasing (17%). Low stable was the most prevalent class, and was characterized by higher maternal warmth and lower maternal disrespect and adolescent irritability while high persistent was characterized by the opposite maternal characteristics. Significant gender differences in class membership were observed. The results highlight the importance of identifying different trajectories of depressive symptoms and specific predictors of each trajectory. The association of parenting dimensions with trajectories of persistent depressive symptoms provides evidence that parenting can serve as both a protective and risk factor for adolescent adjustment.

[The trajectory of depressive symptoms from childhood to adolescence and targets for preventive intervention]

Cette étude longitudinale s'intéresse à la trajectoire développementale des symptômes de dépression sur une période de cinq ans entre l'enfance et l'adolescence ainsi qu'à ses facteurs associés. À partir de l'analyse de courbes de croissance latente (Latent Growth Model-LGM), les résultats indiquent que les symptômes de dépression augmentent entre l'âge de 11-12 ans et 15-16 ans chez les filles, mais non chez les garçons. Cependant, pour chacun des sexes, la variance de la pente de la trajectoire reflète l'hétérogénéité des sous-groupes, révélant que les trajectoires varient chez les individus. Parmi les facteurs mesurés au temps 1 de l'étude, ceux qui sont le plus étroitement associés à la variation longitudinale des symptômes dépressifs sont le soutien des amis pour les deux genres et l'âge pour les filles. Plusieurs facteurs sont également associés à la présence de dépression au temps initial. Les cibles d'intervention pour une prévention universelle de la dépression chez les jeunes sont ensuite discutées et un programme visant le développement de facteurs de protection chez les adolescents est présenté

Identifying depressive symptom trajectory groups among Korean adults and psychosocial factors as group determinants

BACKGROUND

Longitudinal research is needed to examine the depressive symptom trajectories of different groups during adulthood and their antecedents and consequences, because depressive symptoms may be changeable and heterogeneous over time.

AIMS

This study examined the number of trajectory groups describing the depressive symptoms of Korean adults, as well as the shape of the trajectories and the association between trajectory group membership and psychosocial factors identified based on the ecosystem model.

METHOD

This study used Nagin's semi-parametric group-based modeling to analyze Year 1 to Year 7 data from Korea Welfare Panel Survey (N = 13,735), a nationally representative sample of community-dwelling adults.

RESULTS

Three distinct trajectory groups were identified: a low stable depressive symptoms group, a moderate depressive symptoms group and a high depressive symptoms group. Result from multinominal logit analysis showed that all psychosocial factors except family relationships affected the likelihood of membership in the three depressive symptoms groups. Especially, self-esteem was the psychosocial factor with the largest impact on depressive symptom trajectory group membership. When screening for depressive symptoms, individuals with a low socioeconomic status should be a primary concern and intervention should be made available to them.

CONCLUSION

Prevention or intervention with members of the identified trajectory groups would likely require integrative approaches targeting psychosocial factors across multiple contexts.

Differential risk for late adolescent conduct problems and mood dysregulation among children with early externalizing behavior problems

To investigate the differential emergence of antisocial behaviors and mood dysregulation among children with externalizing problems, the present study prospectively followed 317 high-risk children with early externalizing problems from school entry (ages 5-7) to late adolescence (ages 17-19). Latent class analysis conducted on their conduct and mood symptoms in late adolescence revealed three distinct patterns of symptoms, characterized by: 1) criminal offenses, conduct disorder symptoms, and elevated anger ("conduct problems"), 2) elevated anger, dysphoric mood, and suicidal ideation ("mood dysregulation"), and 3) low levels of severe conduct and mood symptoms. A diathesis-stress model predicting the first two outcomes was tested. Elevated overt aggression at school entry uniquely predicted conduct problems in late adolescence, whereas elevated emotion dysregulation at school entry uniquely predicted mood dysregulation in late adolescence. Experiences of low parental warmth and peer rejection in middle childhood moderated the link between early emotion dysregulation and later mood dysregulation but did not moderate the link between early overt aggression and later conduct problems. Thus, among children with early externalizing behavior problems, increased risk for later antisocial behavior or mood dysfunction may be identifiable in early childhood based on levels of overt aggression and emotion dysregulation. For children with early emotion dysregulation, however, increased risk for mood dysregulation characterized by anger, dysphoric mood, and suicidality--possibly indicative of disruptive mood dysregulation disorder--emerges only in the presence of low parental warmth and/or peer rejection during middle childhood.

Longitudinal Stability of the Beck Depression Inventory II

In a six-wave longitudinal study with two cohorts (660 adolescents and 630 young adults), this study investigated the longitudinal stability of the Beck Depression Inventory II (BDI-II) using the Trait-State-Occasion (TSO) model. The results revealed that the full TSO model was the best fitting representation of the depression measured by the BDI-II for both cohorts. It was found that the trait components explained more than 50% of the state variance of the BDI-II scores in both cohorts, and the occasion-specific factor explained about 7% to 12% of variances. The occasion-specific variance was more stable (occasion stability) and somewhat higher in the younger cohort. Implications regarding the longitudinal stability of the BDI-II measure are discussed.
