Depression from preschool to adolescence - five faces of stability

Siblings in families of children with chronic disorders: a model of risk and protective factors

OBJECTIVE

We empirically tested a family systems model's ability to explain variance in psychosocial adjustment among siblings of children with chronic developmental and physical disorders (CDs). The model included the impact of CD severity, family social support, parental mental health, and parent-sibling communication quality. We hypothesized that family social support would moderate the relationship between CD severity and parent mental health, and that sibling-reported communication quality with their parents would mediate the relationship between parent mental health and sibling psychosocial adjustment.

METHODS

We used baseline data from a sibling intervention trial (SIBS-RCT) comprising 288 families with siblings aged 8-16 years and their parents, recruited from health services and user organizations. Parents reported CD severity, parental mental health, and family social support. Siblings self-reported their psychosocial adjustment, including mental health, CD-related adjustment, quality of life, and prosocial behavior. We employed structural equation modeling to test the hypothesized relationships.

RESULTS

Higher parent-sibling communication quality was significantly associated with better sibling-reported quality of life and more prosocial behavior. Lower levels of paternal depression were significantly associated with better sibling-reported quality of life and mental health, whereas maternal depression was not. We did not find support for the hypothesized mediating and moderating pathways for family social support and parent-sibling communication.

CONCLUSIONS

The findings highlight the importance of addressing paternal mental health and parent-sibling communication in promoting sibling psychosocial adjustment. Future studies should use comprehensive, multi-informant approaches and consider the complex interplay of family factors in the context of childhood CD.

Psychometric Properties of the Metacognitions Questionnaire-30 (MCQ-30) in Older Norwegian Adolescents

Dysfunctional metacognitive beliefs have been established as a transdiagnostic correlate of anxiety and depression in adults and are considered a central mechanism of persistent emotional distress according to the metacognitive model of psychological disorders. However, the importance of metacognitions for distress and emotional disorder in adolescence is far less researched, and to investigate this further there is a need for reliable and valid assessment tools. The Metacognitions Questionnaire-30 (MCQ-30) might be a suitable and valid assessment tool in adolescents with the implication that it can be used to research the role of metacognitions in youth mental health and track how metacognitions change and relate to outcomes over time from adolescence to adulthood. We therefore aimed to examine the psychometric properties of the MCQ-30 in an Upper Secondary School-sample of 494 Norwegian adolescents, aged 16- to 18-years old. A confirmatory factor analysis indicated a good fit for the proposed five-factor structure and evidence for measurement invariance was supported across sex and groups of anxiety severity. The factors showed acceptable to good internal consistency and there was support for convergent validity. In conclusion, these findings indicate that the adult version of the MCQ-30 can be applied in Norwegian adolescents from 16-years old.

Preschool Mood Disorders: A Review of the Literature from 2017 to 2024

Depression symptoms that onset during early childhood are increasingly recognized as a significant public health concern. A proliferation of research over the last 2 decades has identified preschool depression as a diagnostic reality that is associated with a severe and persistent course of depression throughout the lifespan. The current review summarizes the research on preschool depression from the last 7 years (2017-2024), with a particular focus on the assessment of, factors and outcomes associated with, neurobiological underpinnings of, and treatments for preschool depression. We also discuss potential avenues of inquiry that further elucidate the nature of preschool depression.

Prevalence and correlates of post-traumatic stress disorder and depression among welfare- and justice-involved adolescents in Nigeria

Background: Childhood maltreatment (CM) is higher among welfare- and justice-involved youth than in those not involved in these systems, which increases the risk of depression and post-traumatic stress disorder (PTSD). However, the mechanisms underlying the link between CM and these two psychiatric conditions are less well understood among at-risk populations in low- and middle-income countries.Objective: This study attempts to fill this gap by examining the prevalence of and risk factors for depression and PTSD among at-risk groups in Nigeria.Method: A cross-sectional research design using multistage sampling was adopted. The sample comprised 205 adolescents: justice-involved [102 (49.8%)] and welfare-involved [103 (50.2%)]. In total, 151 (73.7%) were males, while 54 (26.3%) were females. Multivariate logistic regression analysis and multivariate analysis of variance were applied.Results: The results showed that 66.1% of welfare-involved adolescents and 69.6% of justice-involved adolescents reported PTSD, while 68.9% of welfare-involved adolescents and 75.5% of justice-detained adolescents reported depression. Neglect (OR = 0.253; 95% CI 0.146-0.571; p < .001) and witnessing violence (OR = 0.230; 95% CI 0.114-0.597; p < .004) predicted depression. Emotional abuse (OR = 0.186; 95% CI 0.090-0.80; p < .015), witnessing violence (OR = 0.147; 95% CI 0.014-0.876; p < .043), neglect (OR = 0.187; 95% CI 0.14-0.90; p < .008), and physical abuse (OR = 0.27; 95% CI 0.254-0.937; p < .001) predicted PTSD. Also, PTSD significantly differed based on type of placement (F = 6.08, p < .014, η2 = .029), but depression did not differ based on type of placement (F = 2.46, p > .118, η2 = .012).Conclusions: CM profiles are risk factors in PTSD and depression among at-risk groups. CM screening should be included in mental health services of out-of-home placements to prevent the cycle of mental health problems and reoffending. Trauma-focused and cognitive-behavioural therapies have the potential to alleviate the suffering of traumatized adolescents.

Childhood Predictors of Nonsuicidal Self-Injury in Adolescence: A Birth Cohort Study

OBJECTIVE

Nonsuicidal self-injury (NSSI) is rare in childhood but becomes prevalent in adolescence, which suggests that early intervention might be indicated. As childhood predictors of NSSI in adolescence are largely unknown, identifying these predictors was the aim of this study.

METHOD

In a birth cohort sample (n = 759) of Norwegian children, NSSI at 12, 14, or 16 years of age was regressed on predictors of NSSI at age 6 (parental factors: depression, parenting stress, negativity/hostility, emotional availability to the child; child factors: temperamental negative affectivity, emotion regulation, symptoms of emotional and behavioral disorders; external events: victimization from bullying, serious negative life events). Semistructured clinical interviews with adolescents and their parents were used to assess DSM-5-defined NSSI and NSSI disorder.

RESULTS

NSSI during the preceding 12 months at 12, 14, or 16 years of age was reported by 81 adolescents (10.0%, 95% CI 8.2-11.9), and NSSI disorder was reported by 20 adolescents (2.7%, 95% CI 1.9-3.8). In multivariable logistic regression analysis, female gender (odds ratio 11.6, 95% CI 4.0-33.5), parenting stress (odds ratio 4.8, 95% CI 1.4-16.5), and parental negativity/hostility (odds ratio 1.8, 95% CI 1.2-2.7) predicted NSSI, whereas child factors and external events were not predictive.

CONCLUSION

Parental factors when the child is 6 years of age-parenting stress and negativity/hostility toward the child-predict NSSI in adolescence. Universal and indicated programs targeting these aspects of parenting during childhood might reduce NSSI in adolescence.

PLAIN LANGUAGE SUMMARY

Almost 1 in 4 adolescents engage in deliberate self-harm without wanting to die from it. However, childhood predictors of nonsuicidal self-injury are largely unknown. This study from Norway followed 759 children from birth until adolescence. The authors found that children who perceived their parents as more negative and hostile at 6 years old were at increased risk of engaging in self-injury when they became adolescents. Children whose parents reported more stress in the parenting role were also at increased risk of engaging in self-harm during adolescence. The authors conclude alleviating parental stress and improving parent-child relations at an early age might decrease the risk of adolescent self-harm.

Depression and Personality Traits Across Adolescence-Within-Person Analyses of a Birth Cohort

Depressive symptoms and personality traits covary in adolescents, but our understanding of the nature of this relation is limited. Whereas a predisposition explanation posits that specific personality traits increase the vulnerability for developing depression, a scar explanation proposes that depression may alter premorbid personality. Attempts to test these explanatory models have relied on analyses that conflate within-person changes and between-person differences, which limits the implications that can be drawn. Moreover, research on the early adolescent years is lacking. The present study therefore examined within-person associations between depressive symptoms and Big Five personality traits across ages 10 to 16. Children (n = 817; 49.9% boys) and parents from two birth cohorts in Trondheim, Norway, were assessed biennially with clinical interviews capturing symptoms of major depressive disorder and dysthymia, and self-reported Big Five personality traits. Analyses were conducted using a random intercept cross-lagged panel model, which accounts for all unmeasured time-invariant confounding effects. Increased Neuroticism predicted an increased number of depressive symptoms-and increased depressive symptoms predicted increased Neuroticism-across ages 10 to 14. Moreover, increased depressive symptoms forecast reduced Extraversion across ages 10 to 16, and reduced Conscientiousness from ages 12 to 14. Increases in Neuroticism may contribute to the development of depressive symptoms-in line with the predisposition model. As regards the scar model, depression may have an even wider impact on personality traits: increasing Neuroticism and reducing Extraversion and Conscientiousness. These effects may already be present in the earliest adolescent years.

Psychometric properties of the Norwegian version of the Strength and Difficulties Questionnaire in a preschool sample

PURPOSE

The Strength and Difficulties Questionnaire (SDQ) is widely used internationally, however less so in preschool populations and validations studies are thus needed. This study examined the psychometric properties of the Norwegian version parent report of the SDQ - preschool version (SDQ 2-4).

MATERIALS AND METHODS

Parents of 289 Norwegian children in the age span 1-6 years old filled out the SDQ 2-4, the Child Behavior Checklist (CBCL), and background information. Internal consistency, factor structure, and convergent validity were assessed.

RESULTS

The results showed satisfying internal consistency for the total difficulties score, but worse for some of the subscales. The five-factor structure showed a good fit. Good convergent and divergent validity was found in terms of correlations with CBCL. Sex differences were found on all scales, boys scoring higher on all problem scales.

CONCLUSIONS

The SDQ 2-4 can be a promising instrument to screen for emotional and behavioral difficulties among Norwegian preschoolers, particularly in high-risk populations.

Continuity in child mental health from preschool years to adolescence in parental migration contexts: Evidence from a longitudinal study in Thailand

Our analysis employed the life-course approach to examine whether and how mental health during the preschool stage could predict mental health during adolescence in the Thai context, where migration of parents is common. We used the longitudinal data set of the 2008 and 2021 Child Health and Migrant Parents (CHAMPSEA)-Thailand. The baseline survey of CHAMSEA-Thailand gathered data from 1030 households that met the eligibility criteria, each having a child within one of the two specified age ranges (aged 3-5 or 9-11). Our analysis used the baseline data of children aged 3 to 5 years old who were 16 to 18 years old in the subsequent survey (N = 404). In both surveys, the mental health of children was measured using the SDQ (total difficulties scores), a global standard tool for assessing children's mental health. Parental migration measured whether the parent(s) were international migrants when the child was 3 to 5 years old at the baseline. Results showed a significant, positive impact of the SDQ total difficulties scores of children aged 3 to 5 on their SDQ total difficulties scores when they grew up to 16 to 18 years old. Findings also revealed that experiencing parental international migration during the early life stage led to adverse effects on individuals' mental health when they became adolescents.

Global burden of depression or depressive symptoms in children and adolescents: A systematic review and meta-analysis

BACKGROUND

Depression is the leading cause of health-related disability. A proportion of depression cases begin in childhood and increase dramatically during adolescence. This systematic review and meta-analysis aimed to estimate the global prevalence of depression or depressive symptoms in children and adolescents and explore the temporal and regional distribution of depression or depressive symptoms.

METHODS

This systematic review and meta-analysis identified peer-reviewed literature published through April 8, 2023, using the MEDLINE, Embase and APA PsycINFO databases, supplemented by reverse reference searches. Observational studies published in English and based on validated instruments with prevalence data on depression or depressive symptoms in children and adolescents aged ≤18 years were eligible. Random-effects meta-analysis and meta-regression analysis were performed using R software.

RESULTS

This systematic review and meta-analysis included a total of 96 studies (29 countries, 528,293 participants) published between 1989 and 2022. The pooled prevalence of mild-to-severe, moderate-to-severe, and major depression were 21.3 % (95%CI, 16.7 %-26.7 %), 18.9 % (95%CI, 14.6 %-24.2 %), and 3.7 % (95%CI, 2.7 %-5.1 %) respectively. Meta-regression analysis showed that from 1989 to 2022, the prevalence of mild-to-severe and moderate-to-severe depression increased over time (P = 0.002, P = 0.034, respectively), but the prevalence of major depression did not change significantly (P = 0.636).

LIMITATIONS

Only English articles were included. There was significant heterogeneity across the included studies. The studies included were mostly based on self-report scales to assess depressive symptoms.

CONCLUSION

In this systematic review, about one in five children and adolescents globally suffered from depression or had depressive symptoms, and this proportion was increasing over time.

Course of child social-emotional and sleep symptoms, parental distress and pandemic-related stressors during COVID-19

Research on the longitudinal courses of child social-emotional symptoms and sleep during the COVID-19 pandemic within societies would be of key value for promoting child well-being in global crises. We characterized the course of children's social-emotional and sleep symptoms before and throughout the pandemic in a Finnish longitudinal cohort of 1825 5- to 9-year-old children (46% girls) with four follow-up points during the pandemic from up to 695 participants (spring 2020-summer 2021). Second, we examined the role of parental distress and COVID-related stressful events in child symptoms. Child total and behavioral symptoms increased in spring 2020 but decreased thereafter and remained stable throughout the rest of the follow-up. Sleep symptoms decreased in spring 2020 and remained stable thereafter. Parental distress was linked with higher child social-emotional and sleep symptoms. The cross-sectional associations between COVID-related stressors and child symptoms were partially mediated by parental distress. The findings propose that children can be protected from the long-term adverse influences of the pandemic, and parental well-being likely plays a mediating role between pandemic-related stressors and child well-being. Further research focusing on the societal and resilience factors underlying family and child responses to the pandemic is warranted.

Sexual Attraction and Non-Suicidal Self-Harm: The Role of Stressors and Psychological Mediators

Non-suicidal self-harm (NSSH) is a serious concern for the well-being of youth. Stressors relate to greater NSSH risk, such as being non-heterosexual in a heteronormative society. Other stressors may include traumatic experiences. These relationships may be mediated by psychological factors (depressed mood, anxiety, anger, and self-esteem) as well as contextual factors (support from parents and peers). The purpose of this study was to examine NSHH ideation and behavior among Icelandic youth, as well as relationships with stressors and mediators. Students in Icelandic high schools (N = 8921, 50.8% female) completed an in-class survey in the year 2016. Results showed an elevated risk of NSSH ideation and behavior among bisexual and homosexual youth. Mediation analyses showed that, for girls, being bisexual related to greater NSSH ideation and behavior, and these relationships were mediated by depressed mood, anger, and self-esteem, as well as by support from parents and peers. For boys, however, both homosexual and bisexual attraction related to greater risk for NSSH ideation and behavior, which was mediated by depressed mood, anger, and self-esteem. These results suggest that NSSH risk factors vary by gender and, therefore, they may benefit from different interventions to stop and prevent this behavior. This is the first study of its kind in Iceland, where sexual minority stress may need further study within the Nordic context.

Investigating the psychometric properties of PaRCADS-Parenting to Reduce Child Anxiety and Depression Scale in a Norwegian sample

OBJECTIVES

Parents play a pivotal role in child development and several parental factors have been identified as risk or protective factors for childhood anxiety and depression. To assess and target these parental factors in interventions, there is a need for a comprehensive, easy-to-use instrument.

METHOD

This study aimed to investigate the psychometric properties of an adapted version of the Parenting to Reduce Child Anxiety and Depression Scale, PaRCADS(N) in a Norwegian community sample (N = 163) of parents of children aged 8-12 years.

RESULTS

Our findings indicate that PaRCADS(N) has acceptable psychometric properties. These results are comparable to those of the original study of the PaRCADS in Australia.

CONCLUSION

Based on these results, we recommend that PaRCADS(N) can be utilized by health care workers as a tool for assessment and identification of parental practices related to child anxiety and/or depression to target relevant risk and protective factors in treatment and prevention.

Assessment of Depression in Adults and Youth

This article selectively reviews the key issues and measures for the assessment of depressive disorders and symptoms in youth and adults. The first portion of the article addresses the nature and conceptualization of depression and some key issues that must be considered in its assessment. Next, the diagnostic interview and clinician- and self-administered rating scales that are most widely used to diagnose, screen for, and assess the severity of depression in adults and youth are selectively reviewed. In addition, the assessment of three transdiagnostic clinical features (anhedonia, irritability, and suicidality) that are frequently associated with both depression and other forms of psychopathology is discussed. The article concludes with some broad recommendations for assessing depression in research and clinical practice and suggestions for future research.

Estimated Prevalence of Depressive Disorders in Children From 2004 to 2019: A Systematic Review and Meta-Analysis

Importance

Depression during childhood (ie, age <13 years) poses a major health burden. Recent changes in environmental and lifestyle factors may increase children's risk of mental health problems. This has been reported for anxiety disorders, but it is unclear whether this occurs for depressive disorders.

Objective

To provide prevalence estimates for the depressive disorders (ie, major depressive disorder [MDD], dysthymia, disruptive mood dysregulation disorder [DMDD], and overall) in children, and whether they have changed over time.

Data Sources

The MEDLINE, PsycINFO, Embase, Scopus, and Web of Science databases were searched using terms related to depressive disorders, children, and prevalence. This was supplemented by a systematic gray literature search.

Study Selection

Studies were required to provide population prevalence estimates of depressive disorder diagnoses (according to an established taxonomy and standardized interviews) for children younger than 13 years, information about participants' year of birth, and be published in English.

Data Extraction and Synthesis

Data extraction was compliant with the Meta-Analysis of Observational Studies in Epidemiology guidelines. A total of 12 985 nonduplicate records were retrieved, and 154 full texts were reviewed. Data were analyzed from 2004 (the upper limit of a previous review) to May 27, 2023. Multiple proportional random-effects meta-analytic and mixed-effects meta-regression models were fit.

Main Outcomes and Measures

Pooled prevalence rates of depressive disorders, prevalence rate differences between males vs females and high-income countries (HICs) vs low-and middle-income countries (LMICs), and moderating effects of time or birth cohort.

Results

A total of 41 studies were found to meet the inclusion criteria. Pooled prevalence estimates were obtained for 1.07% (95% CI, 0.62%-1.63%) for depressive disorders overall, 0.71% (95% CI, 0.48%-0.99%) for MDD, 0.30% (95% CI, 0.08%-0.62%) for dysthymia, and 1.60% (95% CI, 0.28%-3.90%) for DMDD. The meta-regressions found no significant evidence of an association with birth cohort, and prevalence rates did not differ significantly between males and females or between HICs and LMICs. There was a low risk of bias overall, except for DMDD, which was hindered by a lack of studies.

Conclusions and Relevance

In this systematic review and meta-analysis, depression in children was uncommon and did not increase substantially between 2004 and 2019. Future epidemiologic studies using standardized interviews will be necessary to determine whether this trend will continue into and beyond the COVID-19 pandemic.

Parental drinking, mental health and educational level, and offspring's subsequent prescription drugs treatment for sleep problems. A longitudinal HUNT survey and registry study

BACKGROUND

Parental drinking, mental health and family socioeconomic status are all associated with offspring sleep problems, but there is a paucity of research that considers the effect of risk factors, as they co-occur within and across families. Also, sleep problems are closely linked with mental health problems. Disentangling the effects on one or the other are important. We examined whether parental risk constellations are differently associated with offspring's subsequent prescription drug use for sleep problems during nine years with or without prescription drug use for anxiety and/or depression.

METHODS

The sample included 8773 adolescent offspring of 6696 two-parent families who participated in the Nord-Trøndelag Health Study in Norway. The exposures were five parental risk constellations, previously identified via Latent Profile Analysis, characterized by drinking frequencies and quantities, mental health, and years of education. The outcomes were dispensed prescription drugs in offspring during 2008-2016 for (a) only sleep problems (b) sleep problems and anxiety/depression or (c) only anxiety/depression. We used multinomial logistic regression to model the odds of the outcomes.

RESULTS

Compared to the overall low-risk parental constellation, none of the risky constellations were significantly associated with increased risk of being dispensed prescription drugs only for sleep problems. Offspring from two different risk profiles were at increased risk for being dispensed both sleep and anxiety/depression prescription drugs. These were parental profiles marked by (1) low education, symptoms of mental health problems and weekly binge drinking in both parents (OR 1.90, CI = 1.06;3.42); and (2) frequent heavy drinking in both parents and symptoms of mental health problems in fathers (OR 3.32, CI = 1.49;7.39). Offspring from the risk profile with lowest parental education had increased risk of only anxiety/depression prescription drugs (OR 1.25, CI = 1.05;1.49).

CONCLUSION

Our findings suggest that parental risk constellations are not associated with increased risk of offspring receiving sleep medications without also receiving anxiety/depression medications, as two risk constellations were associated with increased risk of dispensation of both sleep and anxiety/depression prescription drugs. Receiving both may be an indication of severity. The findings underscore the importance of including measures of mental health problems when investigating sleep problems to avoid misattribution of effects.

Heterotypic and homotypic continuity in psychopathology: a narrative review

Psychopathology is a process: it unfolds over time and involves several different factors. To extend our knowledge of such process, it is vital to understand the trajectories that lead to developing and maintaining a specific disorder. The construct of continuity appears very useful to this aim. It refers to the consistency, similarity, and predictability of behaviors or internal states across different developmental phases. This paper aims to present a narrative review of the literature on homotypic and heterotypic continuity of psychopathology across the lifespan. A detailed search of the published literature was conducted using the PsycINFO Record and Medline (PubMed) databases. Articles were included in the review based on the following criteria: (1) publication dates ranging from January 1970 to October 2022; and (2) articles being written in the English language. To ensure a thorough investigation, multiple combinations of keywords such as "continuity," "psychopathology," "infancy," "childhood," "adolescence," "adulthood," "homotypic," and "heterotypic" were used. Articles were excluded if exclusively focused on epidemiologic data and if not specifically addressing the topic of psychopathology continuity. The literature yielded a total of 36 longitudinal studies and an additional 190 articles, spanning the research published between 1970 and 2022. Studies on continuity focus on the etiology of different forms of mental disorders and may represent a fundamental resource from both a theoretical and clinical perspective. Enhancing our understanding of the different trajectories beneath psychopathology may allow clinicians to implement more effective strategies, focusing both on prevention and intervention. Since literature highlights the importance of early detection of clinical signs of psychopathology, future research should focus more on infancy and pre-scholar age.

Intraindividual phenotyping of depression in high-risk youth: An application of a multilevel hidden Markov model

BACKGROUND

Traditionally, depression phenotypes have been defined based on interindividual differences that distinguish between subgroups of individuals expressing distinct depressive symptoms often from cross-sectional data. Alternatively, depression phenotypes can be defined based on intraindividual differences, differentiating between transitory states of distinct symptoms profiles that a person transitions into or out of over time. Such within-person phenotypic states are less examined, despite their potential significance for understanding and treating depression.

METHODS

The current study used intensive longitudinal data of youths (N = 120) at risk for depression. Clinical interviews (at baseline, 4, 10, 16, and 22 months) yielded 90 weekly assessments. We applied a multilevel hidden Markov model to identify intraindividual phenotypes of weekly depressive symptoms for at-risk youth.

RESULTS

Three intraindividual phenotypes emerged: a low-depression state, an elevated-depression state, and a cognitive-physical-symptom state. Youth had a high probability of remaining in the same state over time. Furthermore, probabilities of transitioning from one state to another did not differ by age or ethnoracial minority status; girls were more likely than boys to transition from a low-depression state to either the elevated-depression state or the cognitive-physical symptom state. Finally, these intraindividual phenotypes and their dynamics were associated with comorbid externalizing symptoms.

CONCLUSION

Identifying these states as well as the transitions between them characterizes how symptoms of depression change over time and provide potential directions for intervention efforts.

Continuity and Stability of Child and Adolescent Depressive Symptoms in South Korea: A Meta-analysis of Longitudinal Studies

Many adolescents in South Korea experience risk-level depressive symptoms due to stress caused by personal and environmental changes. Prior studies investigated various characteristics of depressive symptoms. However, it is unclear when the mean level of depression changes with the development of children and adolescents and whether it is stable relative to one another over time. Thus, it is necessary to closely understand the continuity and stability of depressive symptoms across developmental stages in children and adolescents. In this study, continuity refers to the consistency in a group's mean level of depressive symptoms over time; however, stability refers to the consistency in the relative placement of the levels of depressive symptoms of individuals within a group over time. To comprehensively understand previous studies, this meta-analysis compiled data from 95 South Korean longitudinal studies (N = 200,338; 49.7% females) published between 2000 and 2021. Data were analyzed using a three-level random effects model with a 1-year interval for each age group to integrate effect sizes, followed by a generalized additive mixed model integrating age as a continuous variable. The results indicate that the mean-level continuity of depressive symptoms was relatively high and the rank-order stability was low for the children in elementary school (including both upper and lower grades). Additionally, as the adolescents aged, the mean-level continuity of depressive symptoms slightly decreased while stability increased. When entering early adulthood, the continuity and stability of depressive symptoms converged without significant change. As a result of moderating effect, the female-only group indicated a high level of continuity and stability than the male-only or mixed group. The findings highlight that South Korean childhood is a period of relatively high continuity and low stability. Moreover, female students' depressive symptoms fluctuate more than those of males, suggesting the need for providing effective and appropriate help.

Utility of self- and parent-reported suicidal ideation in early childhood: Prediction of suicidal ideation and psychopathology in adolescence

BACKGROUND

The rates of suicide in youth have increased dramatically, leading to increased interest in routinely screening youth for suicidality. However, data on suicidal ideation (SI) in younger children are sparse, especially with brief self-report measures that can easily be used for screening non-referred samples.

METHODS

We evaluated a community sample of 497 6-year-old children and their parents and followed them into adolescence. SI was assessed via child self-report at ages 6 and 9 using an item from the Children's Depression Inventory, and via parent-report at age 6 using an item from the Early Childhood Inventory. Child psychopathology and functioning were assessed via semi-structured interviews every 3 years from age 6 through 15.

RESULTS

Child endorsement of SI at age 6 did not predict later psychopathology or functioning. Child endorsement of SI at age 9 was associated with attention deficit hyperactivity disorder (ADHD) and disruptive behavior disorders (DBD) diagnoses across the adolescent follow-up assessments. Parent endorsement of child SI predicted an increased likelihood of later SI and non-suicidal self-injury, a higher rate of DBD and externalizing symptoms, and poorer global functioning in adolescence.

CONCLUSIONS

Our results support recommendations against administering SI screening measures to children under the age of 10.

Longitudinal relations between impaired executive function and symptoms of psychiatric disorders in childhood

BACKGROUND

Malfunctioning of executive functions correlates with psychopathology in children. However, the directionality, the extent to which the relation varies for various disorders, and whether prospective relations afford causal interpretations are not known.

METHODS

A community sample of Norwegian children (n = 874) was studied biennially from the age of 6 to 14 years. Executive functions were assessed using the Behavior Rating Inventory of Executive Function Teacher-report and symptoms of psychopathology were assessed using the Preschool Age Psychiatric Assessment (age 6; parents) and Child and Adolescent Psychiatric Assessment (ages 8-14; children and parents). Prospective reciprocal relations were examined using a random intercept cross-lagged panel model that adjusts for all unobserved time-invariant confounders.

RESULTS

Even when time-invariant confounders were accounted for, reduced executive functions predicted increased symptoms of depressive disorders, anxiety disorders, attention-deficit hyperactivity disorder (ADHD), oppositional defiant disorder (ODD), and conduct disorder (CD) 2 years later, even when previous changes in these symptoms were adjusted for. The level of prediction (B = .83, 95% CI [.37, 1.3]) was not different for different disorders or ages. Conversely, reduced executive functions were predicted by increased symptoms of all disorders (B = .01, 95% CI [.01, .02]).

CONCLUSIONS

Reduced executive functioning may be involved in the etiology of depression, anxiety, ADHD, and ODD/CD to an equal extent. Moreover, increased depression, anxiety, ADHD, and ODD/CD may negatively impact executive functioning.

Reciprocal relations between dimensions of Oppositional defiant problems and callous-unemotional traits

Although irritability, headstrong/defiant behavior, and callous-unemotional traits (CU traits) often co-occur, the prospective associations between them are not well known. A general population sample of 622 children was followed up yearly from ages 3 to 12 years and assessed using dimensional measures of irritability, headstrong/defiant, and CU traits with teacher provided information. A random intercept cross-lagged panel model, accounting for all unmeasured time-invariant confounding using the children as their own controls, revealed cross-lagged reciprocal associations between increased headstrong/defiant and increased CU traits at all ages and a unidirectional association from headstrong/defiant to irritability. The findings are consistent with headstrong/defiant behavior and CU traits mutually influencing each other over time and headstrong/defiant behavior enhancing irritability. School-based intervention and prevention programs should take these findings into consideration. They also suggest that irritability acts as a distinct developmental dimension of headstrong/defiant and callous-unemotional behaviors and needs to be addressed independently.

Prevalence and course of anxiety disorders and symptoms from preschool to adolescence: a 6-wave community study

BACKGROUND

The rate of various anxiety disorders in early childhood and whether they continue into middle childhood or adolescence is not known. We therefore report on the prevalence and stability of DSM-5-defined anxiety disorders and their symptoms, capturing the period from preschool to adolescence.

METHODS

By means of interviewer-based clinical interviews, anxiety was measured in a sample of Norwegian children at six measurement points from age 4 to 14 (n = 1,041). To adjust for time-invariant factors, we applied random intercept cross-lagged panel models (RI-CLPMs) capturing within-person changes.

RESULTS

Nearly 10% (95% CI = 7.29, 12.63) had an anxiety disorder at some timepoint. Specific phobia was the most prevalent disorder in early and middle childhood, whereas generalized anxiety disorder (GAD) increased in prevalence and became the most common anxiety disorder at age 14 (4.51%, 95% CI = 2.78, 6.23). When time-invariant confounding was adjusted for, homotypic continuity in anxiety symptoms typically first emerged in late middle childhood or adolescence. Even so, such within-person analyses revealed a heterotypic path from increased number of early childhood symptoms of specific phobia to increased number of GAD symptoms in middle childhood (B = .41, 95% CI = .06, .75). Increased separation anxiety in middle childhood predicted increased symptoms of GAD in adolescence (B = .38, 95% CI = .14, .62), and vice versa (B = .05, 95% CI = .00, .09). Only minor gender differences were revealed.

CONCLUSIONS

Anxiety disorders are prevalent in childhood. In early childhood, anxiety symptoms generally do not predict later anxiety symptoms. In middle childhood, however, such symptoms are less likely to vanish, indicating this developmental period to be particularly important for preventive and treatment efforts.

Psychopathological symptoms as precursors of depressive symptoms in adolescence: a prospective analysis of the GINIplus and LISA birth cohort studies

INTRODUCTION

Depressive symptoms are highly prevalent in adolescence, highlighting the need for early identification of precursors. Research into psychopathological symptoms predicting depressive psychopathology in adolescents is therefore of great relevance. Moreover, given that the prevalence of depressive symptomatology in adolescence shows marked differences between girls and boys, insight into potential sex-specific differences in precursors is important.

METHODS

This study examined the relationships between emotional problems, conduct problems, hyperactivity/inattention, peer problems, and difficulties in prosocial behaviour at age 10 (Strengths and Difficulties Questionnaire), and the presence of depressive symptoms at age 15 (Depression Screener for Teenagers). Using data from 2824 participants of the GINIplus and LISA birth cohorts, the association of each SDQ subscale at age 10 years with the presence of depressive symptoms at age 15 years was analyzed using sex-specific logistic regression, adjusting for potential confounders.

RESULTS

Emotional problems [odds ratio (OR) 1.99, p = 0.002 for boys and OR 1.77, p < 0.001 for girls] and peer problems (OR 2.62, p < 0.001 for boys, OR 1.91, p = 0.001 for girls) at age 10 showed an increased risk for the presence of depressive symptoms at age 15. Additionally, boys with conduct problems at age 10 were at greater risk of showing depressive symptoms in adolescence (OR 2.50, p < 0.001).

DISCUSSION

Based on the identified prospective relationships in our study, it might be of particular importance to tailor prevention approaches during childhood to peer and emotional problems to reduce the risk of depressive psychopathology in adolescence. Moreover, particularly in boys, it seems important to also target conduct problems in childhood as a precursor of depressive symptoms in the adolescent period.

Predictors of diagnostically defined insomnia in child and adolescent community samples: a literature review

Diagnostically defined insomnia is prevalent, persistent, and associated with a range of negative outcomes in childhood and adolescence. To inform prevention and treatment, we need to identify relevant predictors that can be addressed in such intervention efforts. Therefore, a systematic search for longitudinal studies involving child and adolescent samples (ages 4 to 19) examining predictors of diagnostically defined insomnia adjusted for previous insomnia was conducted. The search identified 6419 studies, resulting in six included papers involving five samples (n = 9949) conducted in five different countries (the US, New Zealand, Norway, China, and Japan). Few longitudinal studies investigated the predictors of diagnostically defined insomnia in children and adolescents, and insomnia is rarely defined according to diagnostic manuals. The results suggested that poor mental health (most notably depression) and female sex may be involved in the etiology of diagnostically defined insomnia. Stress might be the most modifiable factor identified. However, the diversity of the predictors studied in previous reports combined with the lack of replication prevent any firm conclusions from being drawn. This review serves as a summary of the best available evidence.

Child and family predictors of insomnia from early childhood to adolescence

BACKGROUND

Insomnia is prevalent among children and adolescents and is associated with a wide range of negative outcomes. Knowledge about its determinants is therefore important, but due to the lack of longitudinal studies, such knowledge is limited. The aim of the present inquiry is to identify child and family predictors of future pediatric insomnia within a psycho-bio-behavioral framework.

METHODS

A representative community sample (n = 1,037) was followed biennially from 4 to 14 years of age (2007-2017). Insomnia was defined based on the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) criteria and was diagnosed by a semistructured clinical interview of children (from age eight years of age) and parents (all ages). Predictors included parent ratings of child emotional reactivity, family functioning, and marital conflict; self-reports of personality; and teacher-rated emotion regulation skills.

RESULTS

Random intercept cross-lagged analyses revealed that within-person increases (ie, relative to the child's typical levels across childhood) in emotional reactivity and decreases in emotion regulation skills predicted insomnia diagnosis two years later from ages 4 to 14 after adjusting for previous insomnia and all unmeasured time-invariant factors. Previous insomnia was the strongest predictor of later insomnia, whereas family functioning and marital conflict did not predict insomnia.

CONCLUSIONS

Increases in emotional reactivity and decreases in emotion regulation skills predicted insomnia above and beyond all unmeasured time-invariant factors and could be targets for interventions. Previous insomnia predicted later insomnia, thereby underscoring the importance of detecting, preventing, and treating insomnia at an early age.

Correlates and Predictors of Chronicity among Adolescents Living in Puerto Rico With a History of Depressive Symptoms

Chronic depression (CD) among Hispanic/Latina(o) youths has been understudied, although chronicity is the biggest risk factor for treatment-resistant depression. We examined CD correlates and predictors among 291 youths (aged 12-18 years) living in Puerto Rico with a history of depressive symptoms. They completed the Children's Depression Inventory (CDI), the Depressive Symptoms Spectrum Assessment Inventory (DSSAI), and the Brief Structured Diagnostic Measure for Depression. We explored CD correlates using Odds Ratios adjusted for CDI-Total scores. With multiple logistic regression, we identified optimal predictors of a history of chronic depressive symptoms (HCDS) or any chronic depressive disorder (HACDD). Living zone (rural), history of depressive disorder, household size (< 4), age of onset of symptoms (< 13 years), death/suicidal thoughts at the first episode, antidepressants use, and scores ≥ 84^th percentile in the DSSAI-Anhedonia subscale, accounted for 37% of HCDS variance. The latter five variables and socioeconomic status (lower-middle/low) best distinguished HACDD and episodic disorders (R ² = .331). Identifying factors that distinguish chronic and episodic depression among Hispanic/Latina(o) youths may help to improve their diagnosis, access to and quality of care, as well as treatment selection, tailoring, and outcomes.
