A longitudinal look at the relation between depression and anxiety in children and adolescents

Does working memory training improve emotion regulation and reduce internalizing symptoms? A pair of three-level meta-analyses

BACKGROUND

Emotional dysfunction is a core feature of many mental disorders. Working memory training (WM-T) is promising to improve emotion regulation and reduce internalizing symptoms (anxiety and depressive symptoms), but the results are mixed. Therefore, we conducted meta-analyses to clarify these mixed results.

METHODS

We searched Web of Science, PubMed, ScienceDirect, and EBSCO to identify relevant studies and screened the references. The effect size was calculated using Hedges' g. Three-level, random-effects models were run using metafor in R.

RESULTS

The current study included 44 articles, of which 29 were involved with emotion regulation, and 30 were involved with internalizing symptoms. The results showed that WM-T could yield emotional benefits, but the benefits were confined to enhancing explicit emotional regulation capacity and reducing anxiety symptoms. For the meta-analysis regarding the effect of WM-T on emotion regulation, there was no significant moderator. For the meta-analysis regarding the effect of WM-T on internalizing symptoms, the emotional valence of the material and control group were statistically significant moderators.

CONCLUSION

WM-T could yield certain emotional effects, but only to improve explicit emotion regulation capacity and reduce anxiety symptoms. In addition, some measures could enhance the effect, such as targeting specific populations, increasing the number of training sessions (≥15) or duration (>450 minutes), using negative material, and using n-back training tasks.

Individualized prediction of anxiety and depressive symptoms using gray matter volume in a non-clinical population

Machine learning is an emerging tool in clinical psychology and neuroscience for the individualized prediction of psychiatric symptoms. However, its application in non-clinical populations is still in its infancy. Given the widespread morphological changes observed in psychiatric disorders, our study applies five supervised machine learning regression algorithms-ridge regression, support vector regression, partial least squares regression, least absolute shrinkage and selection operator regression, and Elastic-Net regression-to predict anxiety and depressive symptom scores. We base these predictions on the whole-brain gray matter volume in a large non-clinical sample (n = 425). Our results demonstrate that machine learning algorithms can effectively predict individual variability in anxiety and depressive symptoms, as measured by the Mood and Anxiety Symptoms Questionnaire. The most discriminative features contributing to the prediction models were primarily located in the prefrontal-parietal, temporal, visual, and sub-cortical regions (e.g. amygdala, hippocampus, and putamen). These regions showed distinct patterns for anxious arousal and high positive affect in three of the five models (partial least squares regression, support vector regression, and ridge regression). Importantly, these predictions were consistent across genders and robust to demographic variability (e.g. age, parental education, etc.). Our findings offer critical insights into the distinct brain morphological patterns underlying specific components of anxiety and depressive symptoms, supporting the existing tripartite theory from a neuroimaging perspective.

The Role of Puberty and Sex on Brain Structure in Adolescents With Anxiety Following Concussion

BACKGROUND

Adolescence represents a window of vulnerability for developing psychological symptoms following concussion, especially in girls. Concussion-related lesions in emotion regulation circuits may help explain these symptoms. However, the contribution of sex and pubertal maturation remains unclear. Using the neurite density index (NDI) in emotion regulation tracts (left/right cingulum bundle [CB], forceps minor [FMIN], and left/right uncinate fasciculus), we sought to elucidate these relationships.

METHODS

No adolescent had a history of anxiety and/or depression. The Screen for Child Anxiety Related Emotional Disorders and Children's Depression Rating Scale were used at scan to assess anxiety and depressive symptoms in 55 concussed adolescents (41.8% girls) and 50 control adolescents with no current/history of concussion (44% girls). We evaluated if a mediation-moderation model including the NDI (mediation) and sex or pubertal status (moderation) could help explain this relationship.

RESULTS

Relative to control adolescents, concussed adolescents showed higher anxiety (p = .003) and lower NDI, with those at more advanced pubertal maturation showing greater abnormalities in 4 clusters: the left CB frontal (p = .002), right CB frontal (p = .011), FMIN left-sided (p = .003), and FMIN right-sided (p = .003). Across all concussed adolescents, lower NDI in the left CB frontal and FMIN left-sided clusters partially mediated the association between concussion and anxiety, with the CB being specific to female adolescents. These effects did not explain depressive symptoms.

CONCLUSIONS

Our findings indicate that lower NDI in the CB and FMIN may help explain anxiety following concussion and that adolescents at more advanced (vs less advanced) status of pubertal maturation may be more vulnerable to concussion-related injuries, especially in girls.

Across ages and places: Unpredictability of maternal sensory signals and child internalizing behaviors

BACKGROUND

Patterns of sensory inputs early in life play an integral role in shaping the maturation of neural circuits, including those implicated in emotion and cognition. In both experimental animal models and observational human research, unpredictable sensory signals have been linked to aberrant developmental outcomes, including poor memory and effortful control. These findings suggest that sensitivity to unpredictable sensory signals is conserved across species and sculpts the developing brain. The current study provides a novel investigation of unpredictable maternal sensory signals in early life and child internalizing behaviors. We tested these associations in three independent cohorts to probe the generalizability of associations across continents and cultures.

METHOD

The three prospective longitudinal cohorts were based in Orange, USA (n = 163, 47.2 % female, Mage = 1 year); Turku, Finland (n = 239, 44.8 % female, Mage = 5 years); and Irvine, USA (n = 129, 43.4 % female, Mage = 9.6 years). Unpredictability of maternal sensory signals was quantified during free-play interactions. Child internalizing behaviors were measured via parent report (Orange & Turku) and child self-report (Irvine).

RESULTS

Early life exposure to unpredictable maternal sensory signals was associated with greater child fearfulness/anxiety in all three cohorts, above and beyond maternal sensitivity and sociodemographic factors. The association between unpredictable maternal sensory signals and child sadness/depression was relatively weaker and did not reach traditional thresholds for statistical significance.

LIMITATIONS

The correlational design limits our ability to make causal inferences.

CONCLUSIONS

Findings across the three diverse cohorts suggest that unpredictable maternal signals early in life shape the development of internalizing behaviors, particularly fearfulness and anxiety.

Fronto-amygdala resting state functional connectivity is associated with anxiety symptoms among adolescent girls more advanced in pubertal maturation

Early adolescence, with the onset of puberty, is an important period when sex differences in anxiety emerge, with girls reporting significantly higher anxiety symptoms than boys. This study examined the role of puberty on fronto-amygdala functional connectivity and risk of anxiety symptoms in 70 girls (age 11-13) who completed a resting state fMRI scan, self-report measures of anxiety symptoms and pubertal status, and provided basal testosterone levels (64 girls). Resting state fMRI data were preprocessed using fMRIPrep and connectivity indices were extracted from ventromedial prefrontal cortex (vmPFC) and amygdala regions-of-interest. We tested moderated mediation models and hypothesized that vmPFC-amygdala would mediate the relation between three indices of puberty (testosterone and adrenarcheal/gonadarcheal development) and anxiety, with puberty moderating the relation between connectivity and anxiety. Results showed a significant moderation effect of testosterone and adrenarcheal development in the right amygdala and a rostral/dorsal area of the vmPFC and of gonadarcheal development in the left amygdala and a medial area of the vmPFC on anxiety symptoms. Simple slope analyses showed that vmPFC-amygdala connectivity was negatively associated with anxiety only in girls more advanced in puberty suggesting that sensitivity to the effects of puberty on fronto-amygdala function could contribute to risk for anxiety disorders among adolescent girls.

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.

The epidemiology of non-suicidal self-injury: lifetime prevalence, sociodemographic and clinical correlates, and treatment use in a nationally representative sample of adults in England

BACKGROUND

Although the clinical importance of non-suicidal self-injury (NSSI) has received increasing recognition, relatively little is known about its epidemiology. The objective of this study was to estimate the lifetime prevalence of NSSI in adults and its association with sociodemographic characteristics, psychiatric disorders, and lifetime treatment for NSSI.

METHODS

A nationally representative face-to-face survey was conducted with 7192 adults aged ≥18 years in England. Respondents were interviewed about engagement in NSSI, psychiatric illness, suicidal thoughts and behavior, and treatment history for this behavior.

RESULTS

The estimated lifetime prevalence rate of NSSI was 4.86%. Younger age, growing up without biological parents in the household, being unmarried, and impoverished backgrounds were associated with NSSI. The majority of respondents with lifetime NSSI (63.82%) had at least one current psychiatric disorder. Most psychiatric conditions were associated with greater odds of lifetime NSSI in multivariate models. NSSI was strongly associated with suicidal ideation and suicide attempts, respectively, even after accounting for psychiatric disorders and sociodemographic covariates. A substantial proportion of respondents with NSSI history (30.92%) have engaged in medically severe self-harm, as indexed by requiring medical attention for this behavior. The majority of respondents with NSSI (56.20%) had not received psychiatric care for this behavior.

CONCLUSIONS

NSSI is prevalent in the general population and associated with considerable psychiatric comorbidity. A high rate of unmet treatment needs is evident among those with this behavior. Those at the greatest lifetime risk for NSSI may also be particularly limited in their resources to cope with this behavior.

The relationship between anxiety and depression under the pandemic: The role of life meaning

Introduction

COVID-19 is a stressor creating much anxiety for the general public, such as anxiety related to possible infection, social distancing, financial strain and uncertainty. As the scientific literature shows that there is an intimate relationship between anxiety and depression, it is important to ask whether anxiety is related to depression under the pandemic and whether spirituality indexed by life meaning can moderate the relationship between anxiety and depression. According to theories highlighting the importance of life meaning, relative to people with a higher level of life meaning, the relationship between anxiety and depression would be stronger in people with a lower level of life meaning.

Methods

Empirically, we collected data in two waves (i.e., before and after the first wave of COVID-19, respectively) from 4,981 adolescents recruited in Sichuan, China. Then, the 41-item “Screen for Child Anxiety Related Emotional Disorders” was employed to measure anxiety symptoms, 20-item “Center for Epidemiological Studies-Depression Scale” was utilized to examine depression symptoms, and the “Spirituality Subscale of the Chinese Positive Youth Development Scale” for assessing life meaning.

Results

We found that anxiety significantly predicted depression at each wave and across time. Second, controlling for Wave 1 depression scores, results showed that a drop in Wave 1 anxiety predicted a drop in depressive symptoms over time. Regarding the relationship between meaning in life and depression, spirituality indexed by meaning in life negatively predicted depression at each wave and over time, and predicted change in depression across time. Finally, multiple regression analyses showed that life meaning moderated the predictive effect of anxiety on depression.

Discussion

The findings support the thesis that spirituality serves as a protective factor for psychological morbidity in Chinese adolescents. The study also suggests the importance of helping adolescents to develop life meaning under COVID-19.

Longitudinal Invariance of the Strengths and Difficulties Questionnaire Across Ages 4 to 16 in the ALSPAC Sample

The Strengths and Difficulties Questionnaire (SDQ) has been widely used to study children's psychosocial development longitudinally; however, such analyses assume longitudinal measurement invariance, that is, they presuppose that symptom manifestations are measured comparably across different ages. Violations of this assumption could bias longitudinal analyses and should therefore be empirically tested. This study tested longitudinal measurement invariance within a confirmatory factor analysis framework in the U.K.-based Avon Longitudinal Study of Parents and Children (N = 13,988). Results indicated that SDQ scores showed configural, metric, scalar, and residual invariance across ages 7, 8, 9, 11, 13, and 16, supporting its use for comparing variances, covariances, and means over time within a latent variable model as well as using observed scores. At age 4, configural invariance was not supported, indicating that mental health symptoms as measured by the SDQ manifest differently at this age, thus necessitating caution when comparing symptoms as measured by SDQ scores at this age to later ages.

Mental health of Turkish medical students during the COVID-19 pandemic

BACKGROUND

The coronavirus disease emerged in 2019, spread in Turkey as all over the world rapidly. In this process, young people began to experience some mental problems due to the fear of contagion, as well as some changes in their lifestyles.

AIMS

In this study it is aimed to investigate anxiety and depression levels of medical school students and the factors associated with these mental problems.

METHOD

The forms were sent over the internet to the officials responsible for medical education at universities in various regions of Turkey. A total of 2,778 medical faculty students were included in the study. Students were asked to fill out the sociodemographic data form, the Patient Health Questionnaire - 9 (PHQ-9), and the Generalized Anxiety Disorder-7 (GAD-7) Test.

RESULTS

Students' 67.3% were female and 31.7% were male. About 90.2% of the students in the PHQ-9 scale had depressive symptoms in the major depressive disorder (MDD) dimension, and 44.5% in the GAD-7 scale had moderate/severe anxiety symptoms. Gender, being a preclinical student, history of psychiatric treatment in the past, currently receiving psychiatric treatment, death of someone due to pandemic, economic and health situation, perception of mental health were found associated with MDD and Moderate/Severe Anxiety symptoms. Students with Anxiety and MDD reported significantly more anxiety about contamination and negative beliefs about precautions' sufficiency.

CONCLUSIONS

It was determined that medical school students in our country showed anxiety and depression at a remarkable level during the pandemic. Examining the underlying causes of these high rates will be beneficial in terms of taking precautions during the long-term pandemic. In literature, there are a limited number of studies on this subject in our country, we believe that our study will be useful in future studies to determine the underlying causes of mental illnesses and what can be done to help students.

Is personality stable and symptoms fleeting? A longitudinal comparison in adolescence

Few investigations have directly compared personality and internalizing symptoms stability within the same sample and have not included personality facets. This study examined rank-order stability and mean-level change of Big Five domains, facets of neuroticism and extraversion, and internalizing symptoms in a sample of 550 adolescent females. Personality and symptoms were assessed every nine months for three years. Three year rank-order stability was higher for personality domains and facets compared to symptoms. Notable exceptions included lower stability of depressivity and positive emotionality facets. Facets and symptoms showed similar mean level change. Overall, we observed modest and variable temporal differences between symptoms and traits; symptoms exhibited high rank-order stability and low mean-level change, but domains and facets were generally more stable.

Anxiety and Depression Symptoms in Children and Adolescents Who Stutter: A Systematic Review and Meta-Analysis

PURPOSE

The purpose of this study was to investigate whether there are elevated symptoms of anxiety or depression in children and adolescents (aged 2-18 years) who stutter, and to identify potential moderators of increased symptom severity.

METHOD

We conducted a preregistered systematic review of databases and gray literature; 13 articles met criteria for inclusion. A meta-analysis using robust variance estimation was conducted with 11 cohort studies comparing symptoms of anxiety in children and adolescents who do and do not stutter. Twenty-six effect sizes from 11 studies contributed to the summary effect size for anxiety symptoms (851 participants). Meta-analysis of depression outcomes was not possible due to the small number of studies.

RESULTS

The summary effect size indicates that children and adolescents who stutter present with increased anxiety symptoms (g = 0.42) compared with nonstuttering peers. There were insufficient studies to robustly analyze depression symptoms, and qualitative review is provided. No significant between-groups differences were reported in any of the depression studies.

CONCLUSIONS

Preliminary evidence indicates elevated symptoms of anxiety in some children and adolescents who stutter relative to peers. There was a tendency toward higher depression scores in this population, although reported between-groups differences did not reach statistical significance. These findings require replication in larger, preferably longitudinal studies that consider factors that may moderate risk. Nevertheless, our findings highlight a need for careful monitoring of mental health and well-being in young people who stutter. Supplemental Materials: http://osf.io/5m6zv.

Parenting Stress Moderates the Relation between Parental Trauma Exposure and Child Anxiety Symptoms

Trauma exposure can lead to poor psychological health not only for those directly affected, but also for their children. Additional research is needed to understand mechanisms in the intergenerational sequelae of traumatic stress. The current study examined parenting stress as a moderator of the association between parents' lifetime trauma exposure and school-aged children's internalizing symptoms (N = 139 dyads). Results of multiple regression analyses showed that the relationships between parental trauma exposure and child separation anxiety and harm avoidance were significant when parenting stress was moderate to high, but not when parenting stress was low. Parental trauma exposure was not significantly associated with child depressive symptoms. Clinical implications include the importance of screening and addressing parents' trauma exposure and parenting stress in the context of child and family mental health services. Further research is needed to explicate the mechanisms linking parents' trauma exposure with child anxiety symptoms.

Validity and Reliability of Youth Anxiety Measure for DSM-5 in Iranian Non-Clinical Children and Adolescents

The present study aimed to explore the validity and reliability of the Persian version of the Youth Anxiety Measure for DSM-5 (YAM-5). Two groups of non-clinical children and adolescents were recruited. The first group (n = 520) was recruited via 4 schools of Tehran, Iran, and only completed the YAM-5. The second group (n = 557) was recruited via 4 schools of Tabriz, Iran. In addition to the YAM-5, they completed another anxiety scale and a depression scale. The exploratory factor analysis of data of the first group revealed a five factor model similar to the original model of the scale. The confimatory factor analysis showed that the five factor model fit with the data of second group. Also, the convergent validity was supported. The current findings, thus, provide support for validity and reliability of Persian version of the YAM-5 in a nonclinical sample of children and adolescents in Iran.

A meta-analysis of emotional regulation outcomes in psychological interventions for youth with depression and anxiety

Difficulties in applying emotional regulation (ER) skills are associated with depression and anxiety symptoms, and are common targets of treatment. This meta-analysis examined whether improvements in ER skills were associated with psychological treatment outcomes for depression and/or anxiety in youth. A multivariate, random-effects meta-analysis was run using metafor in R. Inclusion criteria included studies that were randomized controlled trials (RCTs) of a psychological intervention for depression and/or anxiety in patients aged 14-24, were peer reviewed, were written in English, measured depression and/or anxiety symptoms as an outcome and measured ER as an outcome. Medline, Embase, APA PsycInfo, CINAHL and The Cochrane Library were searched up to 26 June 2020. Risk of bias (ROB) was assessed using the Cochrane Collaboration Risk of Bias 2.0 tool. The meta-analysis includes 385 effect sizes from 90 RCTs with total N = 11,652. Psychological treatments significantly reduced depression, anxiety, emotion dysregulation (k = 13, Hedges' g = 0.54, P < 0.001, 95% confidence interval (CI) = 0.30-0.78) and disengagement ER (k = 83, g = 0.24, 95% CI = 0.15-0.32, P < 0.001); engagement ER also increased (k = 82, g = 0.26, 95% CI = 0.15-0.32, P < 0.001). Improvements in depression and anxiety were positively associated with improved engagement ER skills, reduced emotion dysregulation and reduced disengagement ER skills. Sensitivity considered study selection and publication bias. Longer treatments, group formats and cognitive-behavioural orientations produced larger positive associations between improved ER skills and reduced symptoms. ER skill improvement is linked to depression and anxiety across a broad range of interventions for youth. Limitations of the current study include reliance on self-report measures, content overlap between variables and inability to test the directionality of associations.

Association between anxiety symptoms and atrial fibrillation in a community cohort of Chinese older adults: a case-control study

Background

The association between anxiety and atrial fibrillation (AF) remains unclear. Moreover, this association has rarely been studied in Chinese individuals aged 60 years or older. This study investigated the association between anxiety and AF in a community-based case-control study of older adult residents in urban China.

Methods

The cases and controls were from a community-based study conducted in the Jingansi community in Shanghai, China, between January 2010 and December 2012. A total of 3622 residents aged 60 years or older without severe vision, hearing, or speaking impairments were eligible to participate in the physical examinations and questionnaire survey. AF was assessed based on a previous physician’s diagnosis, electrocardiogram, ambulatory electrocardiogram, or echocardiogram. Anxiety was evaluated using the Zung Self-Rating Anxiety Scale (ZSAS). Using the AF group as a reference, the control group consisted of randomly selected age- and sex-matched individuals in a 1:5 ratio (case:control = 1:5). The association between anxiety and AF in the AF group and the multifactor-matched control group was explored using logistic regression.

Results

In the AF and control groups, after adjusting for a history of coronary heart disease, valvular heart disease, hypertension, stroke, hyperlipidemia, and diabetes, as well as depression score, ZSAS scores (odds ratio 1.07; 95% confidence interval 1.02–1.12; p = 0.003), and anxiety symptoms (odds ratio 3.94; 95% confidence interval 1.06–14.70; p = 0.041) were associated with AF.

Conclusions

Anxiety symptoms were associated with AF in a Chinese older population. This suggests that older adults who have anxiety symptoms may need psychological intervention or treatment in daily life and care.

Digital Phenotype for Childhood Internalizing Disorders: Less Positive Play and Promise for a Brief Assessment Battery

Childhood internalizing disorders, like anxiety and depression, are common, impairing, and difficult to detect. Universal childhood mental health screening has been recommended, but new technologies are needed to provide objective detection. Instrumented mood induction tasks, designed to press children for specific behavioral responses, have emerged as means for detecting childhood internalizing psychopathology. In our previous work, we leveraged machine learning to identify digital phenotypes of childhood internalizing psychopathology from movement and voice data collected during negative valence tasks (pressing for anxiety and fear). In this work, we develop a digital phenotype for childhood internalizing disorders based on wearable inertial sensor data recorded from a Positive Valence task during which a child plays with bubbles. We find that a phenotype derived from features that capture reward responsiveness is able to accurately detect children with underlying internalizing psychopathology (AUC = 0.81). In so doing, we explore the impact of a variety of feature sets computed from wearable sensors deployed to two body locations on phenotype performance across two phases of the task. We further consider this novel digital phenotype in the context of our previous Negative Valence digital phenotypes and find that each task brings unique information to the problem of detecting childhood internalizing psychopathology, capturing different problems and disorder subtypes. Collectively, these results provide preliminary evidence for a mood induction task battery to develop a novel diagnostic for childhood internalizing disorders.

Relationship of affect intolerance with anxiety, depressive, and obsessive-compulsive symptoms in youth

BACKGROUND

Structural research on the construct of affect intolerance (an overarching latent construct indicated by distress tolerance and anxiety sensitivity) has only been conducted in adults. Given that a self-report measure of distress tolerance was recently validated for youth and affect intolerance may be a core mechanism of transdiagnostic interventions for internalizing disorders, we examined how affect intolerance relates to internalizing symptoms in youth. We predicted that a latent affect intolerance factor (indicated by distress tolerance and anxiety sensitivity) would be associated with self and parent-reports of youth anxiety, depressive, and obsessive-compulsive symptoms, controlling for age and gender.

METHODS

At a pre-treatment evaluation, youth with a primary depressive, anxiety, or obsessive-compulsive spectrum disorder (N=277) aged 8-17, and their parent, completed questionnaires.

RESULTS

Greater levels of the affect intolerance factor predicted greater youth- and parent-reported youth anxiety, depression, and obsessive-compulsive symptoms, controlling for age.

LIMITATIONS

Future research should replicate findings in a sample with a greater proportion of depressed youth and utilize experimental or longitudinal methods.

CONCLUSIONS

Importantly, distress tolerance and anxiety sensitivity are core transdiagnostic processes that can be targeted in cognitive-behavioral interventions. Future research should examine how transdiagnostic interventions for youth with internalizing disorders can target these cross-cutting emotional vulnerabilities.

Does Usage of Online Social Media Help Users With Depressed Symptoms Improve Their Mental Health? Empirical Evidence From an Online Depression Community

Online depression communities offer people with depressed symptoms new opportunities to obtain health information and provide social support for each other to fight against the depression. We sought to investigate whether usage of online community help improve depression outcomes and determine which types of usage behaviors have positive or negative effects on depression. We proposed that two dimensions of the sense of belonging (sense of identity and trust) and three dimensions of the sense of support (informational, emotional, and socializing) have significant effects on depression, and further considered gender difference and its effect on depression. We obtained a dataset consisting of 465,337 posts from 244 members from a popular online depression community to test all 10 proposed hypotheses. The results reveal that (i) the sense of shared identity, trust, informational support, and emotional support have positive effects on depression, while socializing support have negative effects on depression, and (ii) the sense of shared identity and trust have more positive effects on depression for female users than male users while socializing support has a more negative effect on depression for female users than for male users. The findings have important practical implications for designers and managers of online depression communities.

Validation of the Arabic version of the Eating Attitude Test in Lebanon: a population study

OBJECTIVES

To validate an Arabic version of the Eating Attitude Test (EAT-26) and identify factors (such as depression, stress, anxiety and body dissatisfaction) that might be associated with disordered eating among a sample of the Lebanese population.

DESIGN

Cross-sectional study.

SETTING

All Lebanese governorates.

PARTICIPANTS

A total of 811 participants randomly selected participated in this 5-month study (January-May 2018).

RESULTS

The EAT-26 scale items converged over a solution of six factors that had an eigenvalue over 1, explaining a total of 60·07 % of the variance (Cronbach's α = 0·895). The prevalence of disordered eating attitudes was 23·8 %. Higher EAT-26 scores (disordered eating attitudes) were significantly associated with higher depression (β = 0·325), higher emotional eating (β = 0·083), daily weighing (β = 3·430), higher physical activity (β = 0·05), starving to reduce weight (β = 4·94) and feeling pressure from TV/magazine to lose weight (β = 3·95).

CONCLUSIONS

The Arabic version of EAT-26 can be a useful instrument for screening and assessing disordered eating attitudes in clinical practice and research. Some factors seem to be associated with more disordered eating attitudes among participants for whom psychological counseling may be needed. Yet, our findings are considered preliminary, and further studies are warranted to confirm them.

Social anxiety and perceptions of likeability by peers in children

The current study aimed to investigate the discrepancy between self-reported and peer-reported likeability among children, and the relation with social anxiety, depression, and social support. In total, 532 children between 7 and 12 years completed questionnaires about social anxiety symptoms, depressive symptoms, and social support, estimated their own likeability, and indicated how much they liked their classmates. Children with higher levels of social anxiety or depression overestimated their likeability less or even underestimated their likeability. Social anxiety symptoms, but not depressive symptoms, were significant predictors of the discrepancy. Social support was positively related to likeability and negatively related to social anxiety, but did not moderate the association between social anxiety symptoms and perception accuracy of likeability. These results are in line with cognitive theories of childhood social anxiety, and they stress the importance of using multi-informant measures when studying the relation between social anxiety and social functioning in children.

Investigating school children’s behavioral and emotional problems using pediatric symptoms checklist-17 in a structural equation modeling framework

The Pediatric Symptom Checklist-17 was originally used in primary care settings with parents to identify their children’s behavioral and emotional problems, but there has been some research supporting use of this scale in school settings. This study examined: (a) the factor structure and measurement invariance of the teacher-rated Pediatric Symptom Checklist-17 and (b) complex relationships among demographic characteristics, behavioral and emotional problems, and learning outcomes using structural equation modeling in elementary schools. A sample of 508 children in grades one and two were rated by their teachers with the Pediatric Symptom Checklist-17. Measures of Academic Progress test was utilized to measure participants’ learning outcomes in reading and math. The results confirmed a three-factor structure of the Pediatric Symptom Checklist-17 (internalizing problems, externalizing problems, and attention problems) and attested the measurement invariance across different demographic groups (i.e. gender, ethnicity, and grade levels). Boys were more likely to have severe attention problems which were associated with lower learning outcomes as seen by Measures of Academic Progress reading and math scores. Attention problems mediated the relationship between gender and learning outcomes. This study has implications for the use of the Pediatric Symptom Checklist-17 in school-based settings. Additionally, it highlights the potential relationships among gender, attention problems, and learning outcomes.

Incidence and recurrence of depression from adolescence to early adulthood: A longitudinal follow-up of the Mexican Adolescent Mental Health Survey

BACKGROUND

Depression is a leading cause of disease burden around the globe, often develops during adolescence and is recurrent. Thus, disentangling risk factors for incidence from those of recurrence during adolescence is relevant and might suggest different strategies for prevention of onset than for relapse. The aim was to evaluate the relative risk of socio-demographic and clinical factors and traumatic events associated to incidence and recurrence of depression in youth from Mexico City.

METHODS

This is a prospective longitudinal general population survey in which 1071 respondents from the Mexican Adolescent Mental Health Survey were interviewed between the ages of 12 and 17 and again eight years later when they were between 19 and 26 years of age. The World Mental Health Composite International Diagnostic Interview evaluated incidence and persistence of major depression and risk factors.

RESULTS

Eight-year incidence was 12.9% while recurrence was 46.1%. Risk factors for incidence (female sex, any incident trauma, and specifically sexual abuse and an other/private event) differed from the risk factors for recurrence (childhood onset and domestic violence) with the exception of having a parent with depression, which was associated to increased risk for both.

LIMITATIONS

The follow-up response rate was limited by inability to locate participants at wave II. Statistical power was limited for persistence due to low rate of depression at wave I.

CONCLUSIONS

Intervening with both depressed and non-depressed children of parents with depression may have beneficial effects on both the development of depression as well as recurrence.

A Genetic Cross-Lagged Study of the Longitudinal Association Between Anxiety and Depressive Symptoms During Childhood

This study documented the etiology contributions between anxiety symptoms (AS) and depressive symptoms (DS) from ages 6-12 years. Teachers assessed AS and DS in 1112 twins at 5 time points. A genetic cross-lagged model was used to estimate genetic/environmental contributions to cross-sectional, cross-age and cross-lag associations. The variance in AS and DS was largely time-specific and more genetic in nature for DS than for AS. Previous DS predicted subsequent DS better than cross-lag or previous common effects, and AS up to age 9 better than previous AS or previous common effects. Thereafter, previous AS predicted subsequent AS. All predictions involved both genetic and unique environment. Suppression effects were found and, when controlled, AS marginally predicted DS from age 7 onward through genetic influences. AS and DS are associated throughout childhood. DS are more stable than AS, and more central to both subsequent AS and DS. AS marginally contribute to subsequent DS.

What Drives Patients Affected by Depression to Share in Online Depression Communities? A Social Capital Perspective

Online depression communities give people additional opportunities to share their experiences and exchange social support to care for themselves in fighting against depression. We aimed to explore what drives patients to share in online depression communities. We used three dimensions of social capital (structural, relational, and cognitive) to explain their sharing behaviors. We further proposed that five factors (social interaction ties, a sense of shared identity, trust, expertise, and a sense of shared values) will have significant, positive effects on sharing behaviors and that there are differences among patients who have spent different lengths of time participating in online depression communities. We then chose a popular online depression community in China as our data source and obtained a dataset consisting of 31,440 posts from 197 members. Then, we employed panel data regression analyses to test all six hypotheses. The results revealed that all five factors had significant, positive effects (p < 0.01) on patients' sharing behaviors, and the effects were significantly different across groups. Our empirical results help designers and managers of online depression communities take specific measures to facilitate community members' access to social capital resources. Meanwhile, our results have implications for existing health management and e-health literature.

Giving Voice to Vulnerable Children: Machine Learning Analysis of Speech Detects Anxiety and Depression in Early Childhood

Childhood anxiety and depression often go undiagnosed. If left untreated these conditions, collectively known as internalizing disorders, are associated with long-term negative outcomes including substance abuse and increased risk for suicide. This paper presents a new approach for identifying young children with internalizing disorders using a 3-min speech task. We show that machine learning analysis of audio data from the task can be used to identify children with an internalizing disorder with 80% accuracy (54% sensitivity, 93% specificity). The speech features most discriminative of internalizing disorder are analyzed in detail, showing that affected children exhibit especially low-pitch voices, with repeatable speech inflections and content, and high-pitched response to surprising stimuli relative to controls. This new tool is shown to outperform clinical thresholds on parent-reported child symptoms, which identify children with an internalizing disorder with lower accuracy (67-77% versus 80%), and similar specificity (85-100% versus 93%), and sensitivity (0-58% versus 54%) in this sample. These results point toward the future use of this approach for screening children for internalizing disorders so that interventions can be deployed when they have the highest chance for long-term success.

Temporal associations between social anxiety and depressive symptoms and the role of interpersonal stress in adolescents

BACKGROUND

Adolescence is characterized by an increased vulnerability for internalizing psychopathologies such as depression and anxiety. A positive association between anxiety and depression has consistently been found in research. However, the specific direction of this association is less clear. In this study, we investigated the temporal associations between (social) anxiety and depressive symptoms. Furthermore, the role of dependent interpersonal stress as a potential mediating factor in these temporal associations was examined.

METHODS

Data were part of a larger longitudinal study on the emotional development of adolescents, which was initiated in February 2013. The total sample consisted of 2011 adolescents between the ages of 11 and 19. Data were analyzed using cross-lagged models.

RESULTS

Bidirectional positive associations were found between social anxiety symptoms and depressive symptoms. However, dependent interpersonal stress was not a mediator in the link between social anxiety and depression. Our results indicate that dependent interpersonal stress seems to be particularly related to depressive symptoms and not to social anxiety symptoms.

CONCLUSIONS

Findings suggest that bidirectional associations between social anxiety and depressive symptoms exist. This implies that clinicians should be specifically vigilant for the development of depressive symptoms in socially anxious adolescents and the development of social anxiety symptoms in depressed adolescents. Our findings further highlight the importance of targeting dependent interpersonal stress in the context of depression.

Cultural variation in temporal associations among somatic complaints, anxiety, and depressive symptoms in adolescence

OBJECTIVE

Different domains of internalizing symptoms (somatic, anxiety, depressive) often occur concurrently, suggesting that they may share common etiology. In longitudinal analyses of internalizing among youth, anxiety is often found to precede depression. However, relatively few studies have also assessed how somatic problems, the third symptom domain, are involved in longitudinal patterns of internalizing. In addition, temporal relations among internalizing symptom domains may vary by cultural group as somatic symptoms are posited to be a more culturally-normative way of communicating or experiencing distress in non-Western, interdependent cultures. Thus, the present study examined longitudinal relations among these three internalizing symptom domains in three ethnocultural adolescent samples.

METHODS

304 European American, 420 Vietnamese American, and 717 Vietnamese adolescents' self-reported internalizing symptoms (somatic, anxiety, depressive) were assessed at three time points, spaced three months apart, using multigroup cross-lagged path analysis.

RESULTS

Anxiety symptoms consistently predicted increases in depressive symptoms in European American adolescents. In contrast, for Vietnamese and Vietnamese American adolescents, the most consistent relation was with somatic complaints predicting increases in anxiety. Anxiety and depressive symptoms bidirectionally predicted each other among the Vietnamese and Vietnamese American adolescents.

CONCLUSIONS

Cultural group differences were evident in the temporal course of internalizing symptoms. The pattern of results have implications for culturally relevant intervention targets, during a developmental period of risk for internalizing disorders.

Early clinical predictors of long-term morbidity in major depressive disorder

AIMS

To identify early clinical factors predictive of later morbidity in major depressive disorder (MDD).

METHODS

We analysed factors associated with long-term depressive morbidity (%-time ill) between a first-lifetime major depressive episode and last follow-up of 116 adults diagnosed with DSM-IV major depressive disorder. Bivariate comparisons were followed by multivariable linear regression modelling.

RESULTS

Three factors were independently associated with an average of 25%-time-depressed over 17 years at risk: (a) agitated-mixed, or psychotic features in initial major depressive episodes, (b) anxiety syndromes prior to a first-lifetime major depressive episode, and (c) anxiety symptoms in childhood.

CONCLUSION

Early anxiety symptoms and syndromes and agitated-mixed or psychotic initial depressive episodes predicted more long-term depressive morbidity in MDD.

Factors associated with depression and anxiety symptoms among children seeking treatment for obesity: A social-ecological approach

BACKGROUND

Children with overweight/obesity are more likely to exhibit symptoms of depression and anxiety than are their peers without overweight/obesity; however, the rates and correlates of depression and anxiety symptoms among children seeking obesity treatment remain unclear.

OBJECTIVES

Examine the prevalence and associated factors of depression and anxiety symptoms among treatment-seeking children with overweight/obesity.

METHODS

Children 7 to 11 years old (N = 241) and their parents completed assessments before beginning family-based behavioral weight-loss treatment. Disorder-specific self-report questionnaires assessed child depression and anxiety. The social-ecological model served as a framework for examining factors associated with depression and anxiety symptoms.

RESULTS

Among our sample, 39.8% (96/241) met clinical cutoffs for depression and/or anxiety symptomatology. Specifically, of these 96, 48 met criteria for both depression and anxiety, 24 for depression only, and 24 for anxiety only. Child eating disorder pathology, parents' use of psychological control (ie, a parenting style characterized by emotional manipulation), and lower child subjective social status were significantly associated with greater child depression symptomatology. Child eating disorder pathology and parent psychological control were significantly associated with greater child anxiety symptomatology.

CONCLUSION

Nearly 40% of children exhibited psychopathology symptoms, and a variety of correlates were found. Thus, pediatric weight-loss providers may consider screening for and addressing mental health concerns (and associated factors) prior to and during treatment.

Anxiety and Depression During Childhood and Adolescence: Testing Theoretical Models of Continuity and Discontinuity

The present study sought to clarify the trajectory (i.e., continuous vs. discontinuous) and expression (i.e., homotypic vs. heterotypic) of anxiety and depressive symptoms across childhood and adolescence. We utilized a state-of-the-science analytic approach to simultaneously test theoretical models that describe the development of internalizing symptoms in youth. In a sample of 636 children (53% female; M _age = 7.04; SD _age = 0.35) self-report measures of anxiety and depression were completed annually by youth through their freshman year of high school. For both anxiety and depression, a piecewise growth curve model provided the best fit for the data, with symptoms decreasing until age 12 (the "developmental knot") and then increasing into early adolescence. The trajectory of anxiety symptoms was best described by a discontinuous homotypic pattern in which childhood anxiety predicted adolescent anxiety. For depression, two distinct pathways were discovered: A discontinuous homotypic pathway in which childhood depression predicted adolescent depression and a discontinuous heterotypic pathway in which childhood anxiety predicted adolescent depression. Analytical, methodological, and clinical implications of these findings are discussed.

Four Social Brain Regions, Their Dysfunctions, and Sequelae, Extensively Explain Autism Spectrum Disorder Symptomatology

Autism spectrum disorder (ASD) is a challenging neurodevelopmental disorder with symptoms in social, language, sensory, motor, cognitive, emotional, repetitive behavior, and self-sufficient living domains. The important research question examined is the elucidation of the pathogenic neurocircuitry that underlies ASD symptomatology in all its richness and heterogeneity. The presented model builds on earlier social brain research, and hypothesizes that four social brain regions largely drive ASD symptomatology: amygdala, orbitofrontal cortex (OFC), temporoparietal cortex (TPC), and insula. The amygdala's contributions to ASD largely derive from its major involvement in fine-grained intangible knowledge representations and high-level guidance of gaze. In addition, disrupted brain regions can drive disturbance of strongly interconnected brain regions to produce further symptoms. These and related effects are proposed to underlie abnormalities of the visual cortex, inferior frontal gyrus (IFG), caudate nucleus, and hippocampus as well as associated symptoms. The model is supported by neuroimaging, neuropsychological, neuroanatomical, cellular, physiological, and behavioral evidence. Collectively, the model proposes a novel, parsimonious, and empirically testable account of the pathogenic neurocircuitry of ASD, an extensive account of its symptomatology, a novel physiological biomarker with potential for earlier diagnosis, and novel experiments to further elucidate the mechanisms of brain abnormalities and symptomatology in ASD.

A randomized controlled trial of a group acceptance-based intervention for cancer survivors experiencing anxiety at re-entry ('Valued Living'): study protocol

Background

Anxiety is a common concern of cancer survivors during the transition from active cancer treatment to cancer survivorship (the re-entry phase). This paper presents the study protocol for a novel group-based behavioral intervention to improve mental health, well-being, and medical use outcomes among anxious cancer survivors at re-entry.

Methods/Design

This two-armed, prospective randomized controlled trial will randomize a minimum of 100 re-entry-phase cancer survivors with moderate to high anxiety to the intervention or a usual care control condition. The intervention is delivered in a group format over 7 weeks; content is based on Acceptance and Commitment Therapy (ACT), an acceptance, mindfulness, and values-based intervention. Participants will be recruited from community cancer care centers and the intervention will be led by the onsite clinical social workers. Participants will be assessed at baseline, mid-intervention, post-intervention, and 3- and 6-month follow-up. ACT participants will complete process measures before the beginning of group sessions 2, 4, and 6; all participants will complete the process measures during the regular assessments. The primary outcome is anxiety symptoms; secondary outcomes include anxiety disorder severity, fear of recurrence, depressive symptoms, cancer-related trauma symptoms, sense of life meaning, vitality/fatigue, and medical utilization.

Discussion

This clinical trial will provide valuable evidence regarding the efficacy of the group ACT intervention in community oncology settings.

Rapid detection of internalizing diagnosis in young children enabled by wearable sensors and machine learning

There is a critical need for fast, inexpensive, objective, and accurate screening tools for childhood psychopathology. Perhaps most compelling is in the case of internalizing disorders, like anxiety and depression, where unobservable symptoms cause children to go unassessed-suffering in silence because they never exhibiting the disruptive behaviors that would lead to a referral for diagnostic assessment. If left untreated these disorders are associated with long-term negative outcomes including substance abuse and increased risk for suicide. This paper presents a new approach for identifying children with internalizing disorders using an instrumented 90-second mood induction task. Participant motion during the task is monitored using a commercially available wearable sensor. We show that machine learning can be used to differentiate children with an internalizing diagnosis from controls with 81% accuracy (67% sensitivity, 88% specificity). We provide a detailed description of the modeling methodology used to arrive at these results and explore further the predictive ability of each temporal phase of the mood induction task. Kinematical measures most discriminative of internalizing diagnosis are analyzed in detail, showing affected children exhibit significantly more avoidance of ambiguous threat. Performance of the proposed approach is compared to clinical thresholds on parent-reported child symptoms which differentiate children with an internalizing diagnosis from controls with slightly lower accuracy (.68-.75 vs. .81), slightly higher specificity (.88-1.00 vs. .88), and lower sensitivity (.00-.42 vs. .67) than the proposed, instrumented method. These results point toward the future use of this approach for screening children for internalizing disorders so that interventions can be deployed when they have the highest chance for long-term success.

The relationship between posttraumatic and depressive symptoms during virtual reality exposure therapy with a cognitive enhancer

Two studies suggest that reductions in posttraumatic symptoms (Aderka et al., 2013) and cognitions (Zalta et al., 2014) precede reductions in depressive symptoms during prolonged exposure (PE) therapy for posttraumatic stress disorder (PTSD) in female assault survivors. The present study explored the temporal relationship between posttraumatic and depressive symptoms in a randomized trial of D-Cycloserine (DCS) versus placebo augmented virtual reality exposure (VRE) therapy for chronic World Trade Center-related PTSD following the September 11, 2001 terrorist attacks. Twenty-five male and female participants were randomly assigned to receive either 100 mg DCS (N = 13) or placebo (N = 12) 90 min before 12 weekly VRE sessions. Participants contributed a total of 280 weekly PTSD Checklist (PCL; Weathers et al., 1993) and Beck Depression Inventory-second edition (BDI-II; Beck et al., 1996) symptom scores. Two sets of mediation analyses for longitudinal mixed models assessed the effects of 1) lagged PCL on BDI-II (Model 1), and 2) lagged BDI-II on PCL (Model 2) in the VRE-DCS and VRE-Placebo treatment groups, respectively. Results revealed reciprocal relations between posttraumatic and depressive symptoms during VRE treatment, although reductions in posttraumatic symptoms led to subsequent reductions in depressive symptoms to a greater extent than the converse. These effects were stronger in the DCS-enhanced group. Findings suggest that VRE primarily decreases posttraumatic symptoms, which in turn leads to decreased depressive symptoms, and that DCS may strengthen these effects.

Differences between self- and peer-rated likability in relation to social anxiety and depression in adolescents with mild intellectual disabilities

BACKGROUND

Social anxiety and depressive symptoms are relatively common in adolescents with Mild to Borderline Intellectual Disabilities (MBID). Unfortunately, there are only a few studies that focus on examining processes underlying social anxiety and depression in these adolescents.

AIMS

The aim was to examine the differences between self- and peer-rated likability in relation to social anxiety and depression in the classroom environment.

METHODS AND PROCEDURES

631 normative non-clinical adolescents with MBID completed questionnaires to measure social anxiety, depression, and the estimation of their own likability by peers. Peer-reported likability was derived from peer-rating scales on likability.

OUTCOMES AND RESULTS

Adolescents with higher levels of social anxiety significantly rated their own likability as lower than their non-anxious peers. However, socially adolescents were equally liked by their peers. Adolescents with higher levels of depression were significantly less liked by their peers, but still underestimated their own likability than adolescents with lower levels of depression.

CONCLUSIONS AND IMPLICATIONS

Social anxiety and depression are linked to a biased interpretation of likability, but only depression is linked to actually being less liked by peers. Social anxiety and depression are partly based on similar underlying cognitive biases.

Temporal dynamics and longitudinal co-occurrence of depression and different anxiety syndromes in youth: Evidence for reciprocal patterns in a 3-year prospective study

BACKGROUND

Depression is highly comorbid with anxiety in youth. It is frequently reported that anxiety precedes depression; however, evidence surrounding the temporal precedence of anxiety over depression is mixed. Many studies of anxiety-depression co-occurrence lump distinct forms of anxiety, obscuring information regarding trajectories of specific anxiety syndromes. This study sought to more accurately describe the development of anxiety and depression over time by moving beyond the question of temporal precedence to investigate a developmentally dynamic model of anxiety-depression co-occurrence.

METHODS

A community sample of 665 youth (M= 11.8, SD= 2.4; 55% female) completed repeated self-report measures of depression and anxiety (social, physical, and separation anxiety) over a 3-year longitudinal study. Prospective associations between distinct syndromes of anxiety with depression were analyzed using an autoregressive cross-lagged path model over four time points.

RESULTS

Physical symptoms and depression symptoms reciprocally predicted each other, above and beyond the stability of either domain. Social anxiety and depression symptoms similarly predicted each other in a systematic pattern.

LIMITATIONS

Our study is limited in its generalizability to other forms of anxiety, like worry. Additional research is needed to determine whether similar patterns exist in clinical populations, and whether these processes maintain symptoms once they reach diagnostic levels.

CONCLUSIONS

The development of syndromes of depression, physical, and social anxiety during childhood and adolescence occurs in a predictable, systematic reciprocal pattern, rather than sequentially and unidirectionally (i.e., anxiety syndromes precede depression). Results are clinically useful for predicting risk for disorder, and demonstrate the necessity of tracking symptom levels across domains.

Effects of Cyberbullying and Cybervictimization on Early Adolescents' Mental Health: Differential Mediating Roles of Perceived Peer Relationship Stress

The purpose of this study was to examine the differential mediational roles of perceived peer relationship stress (PPRS) in accounting for the association between cyberbullying (CB) and cybervictimization (CV) and mental health among early adolescents in cross-sectional data and longitudinal data, respectively. A total of 606 early adolescents completed questionnaires as part of a 3-year longitudinal study on three occasions at 1-year intervals. Structural equation modeling revealed that (1) compared to CB, CV showed a stronger relationship with mental health. (2) In contrast to its role in CV, PPRS did not mediate the link between mental health and CB in both cross-sectional and longitudinal models. PPRS mediated the relationship between CV and mental health in both cross-sectional and longitudinal models. Limitations and practical applications of the study were discussed.

Leveraging After-School Programs to Minimize Risks for Internalizing Symptoms Among Urban Youth: Weaving Together Music Education and Social Development

This study examined a university-community partnership, focusing on mental health promotion within an after-school music program. We pursued two goals: (a) supporting staff around student engagement and behavior management; (b) integrating social-emotional activities into the curriculum. We assessed youth's mental health needs and examined feasibility of social-emotional activities delivered. One-hundred sixty-two youth participated in activities, while a subset of youth (n = 61) and their parents provided information on mental health need. Rates of anxiety and depression symptoms were high, and youth reported high satisfaction with the activities. Results suggest promise of this model for mental health promotion for urban youth.

Effectiveness of a cognitive behavioural therapy-based anxiety prevention programme at an elementary school in Japan: a quasi-experimental study

BACKGROUND

The efficacy of cognitive behavioural therapy (CBT) for anxiety related problems in children is empirically supported. In addition, universal anxiety prevention programmes based on CBT have been demonstrated in recent years. The purpose of this study was to verify the effectiveness of a CBT based original programme 'Journey of the Brave,' aiming to prevent anxiety disorders and anxiety-related problems for Japanese children aged 10-12 years old.

METHODS

Intervention groups from two classes of 5th grade elementary students (n = 41) received ten 45-min programme sessions. The control group was drawn from one class of 5th grade children (n = 31) from a nearby school. All participants completed the Spence Children's Anxiety Scale (SCAS) at pre, post, and 3 months follow-up. Mixed-effects model for repeated measures analysis was conducted.

RESULTS

The mean anxiety score on the SCAS for the intervention group was significantly reduced at both post intervention and 3 months follow-up compared with the control group. The group differences on the SCAS from baseline to post-test were - 5.321 (95% CI - 10.12 to - 0.523, p = 0.030), and at the 3-month follow-up were - 7.104 (95% CI - 11.90 to - 2.306, p = 0.004).

CONCLUSIONS

The effectiveness of the anxiety prevention programme 'Journey of the Brave' was verified though this study using a quasi-experimental design on a small sample.Trial registration: UMIN000009021.

Insomnia mediates the longitudinal relationship between anxiety and depressive symptoms in a nationally representative sample of adolescents

BACKGROUND

Anxiety and depression are commonly comorbid with each other, with anxiety often temporally preceding the development of depression. Although increasingly research has begun to investigate the role of sleep problems in depression, no study has examined insomnia as a mediator in the longitudinal relationship between anxiety and subsequent depression.

METHODS

The current study utilizes data from Waves I, II, and IV of the National Longitudinal Study of Adolescent to Adult Health, a nationally representative prospective study conducted over a 14-year period (n = 20,745, 50.5% female, M age at Wave I = 16.20). Participants completed portions of the Center for Epidemiologic Studies Depression Scale at Waves I and IV to assess depressive symptoms, a six-item anxiety measure at Wave I, and three items assessing insomnia, sleep quality, and sleep duration at Wave II.

RESULTS

Structural equation modeling indicated that insomnia and unrestful sleep significantly mediated the relationship between anxiety and subsequent depression. The relationship between anxiety and depression was not significantly mediated by sleep duration.

CONCLUSIONS

Findings suggest that anxiety may increase risk for the development of later depression through insomnia.
