Gender, Anxiety, and Depressive Symptoms: A Longitudinal Study of Early Adolescents

Symptom Severity and Health Impacts of Functional Tic-Like Behaviors in Youth

BACKGROUND

We performed this study to improve understanding of the relationship between functional tic-like behaviors (FTLBs) and quality of life, loneliness, family functioning, anxiety, depression, and suicidality.

METHOD

This cross-sectional study assessed self-reported quality of life, disability, loneliness, depression, anxiety, family functioning, tic severity, and suicide risk in age- and birth-sex matched youth with FTLBs, Tourette syndrome (TS), and neurotypical controls. We performed specific subanalyses comparing individuals with FTLBs who identified as transgender/gender diverse (TGD) with cisgender individuals.

RESULTS

Eighty-two youth participated (age range 11 to 25, 90% female at birth), including 35 with FTLBs, 22 with TS, and 25 neurotypical controls. A significantly higher proportion of participants with FTLB identified as TGD (15 of 35) than TS (two of 22) and neurotypical control (three of 25) participants. Compared with neurotypical controls, individuals with FTLBs had significantly lower quality of life, greater disability, loneliness, social phobia, anxiety symptoms, depressive symptoms, and suicidality. Compared with individuals with TS, individuals with FTLBs had more school/work absences due to tics, had more depressive symptoms, were more likely to be at high risk for suicidality, and had disability in self-care and life activity domains. There were no significant differences between cisgender and TGD participants with FTLB in any of the domains assessed.

CONCLUSIONS

Youth with FTLB have unique health care needs and associations with anxiety, depression, sex, and gender.

Associations between middle childhood executive control aspects and adolescent substance use and externalizing and internalizing problems

This study examines the degree to which two middle childhood executive control aspects, working memory and combined inhibitory control/flexible shifting, predict adolescent substance use and externalizing and internalizing problems. Participants were 301 children (ages 3-6 years; 48.2% male) recruited from a Midwestern city in the United States and followed into adolescence (ages 14-18 years). Working memory had a statistically significant unadjusted association with externalizing problems (r = -.30, p = .003) in a confirmatory factor analysis. Neither factor significantly predicted any of the adolescent outcomes in a structural equation model that adjusted for each EC aspect, sociodemographic covariates, and middle childhood externalizing and internalizing problems. Stronger prediction of EC aspects might not emerge until they become more fully differentiated later in development.

Protective Factors in the Context of Childhood Bereavement: Youth Gratitude, Future Orientation, and Purpose in Life

The objective of the study was to examine potential associations between positive youth development constructs (gratitude, future orientation, purpose in life) and psychological functioning (posttraumatic stress symptoms, depressive symptoms, maladaptive grief reactions) among bereaved youth and test whether these associations vary by age. A diverse sample of 197 clinic-referred bereaved youth (56.2% female; M = 12.36, SD = 3.18; 36.1% Hispanic, 23.7% White, 20.1% Black, 11.9% Multiracial, and 8.2% another race/ethnicity) completed self-report measures of psychological functioning and positive youth development constructs. Linear regression models indicated that gratitude and purpose were associated with lower posttraumatic stress and depressive symptoms among bereaved youth. Future orientation was associated with higher posttraumatic stress symptoms. Results were consistent across age. If replicated longitudinally, gratitude and purpose may be important protective factors against negative mental health outcomes in the aftermath of losing a loved one.

Do community-related traumatic events affect academic outcomes among adolescents? Quasi-experimental evidence from the Sewol disaster in South Korea

The sinking of the South Korean ferry Sewol in April 2014 claimed a total of 304 lives. Among the victims were 250 students from Dan-won High School in the city of Ansan and 11 of their teachers. For the residents of Ansan, the tragedy marked the beginning of widespread psychological distress and overwhelming grief. Exploiting the disaster's quasi-experimental nature, we employ a difference-in-differences (DID) strategy to measure its impact on the academic performance of Ansan's high school students in 5 major subjects. Using peers from Ansan's neighboring cities as the control group, our results reveal that the disaster impaired performances particularly in mathematics and natural science, a finding that is more pronounced for female students. Our results highlight that it is of uttermost importance to provide comprehensive psychological support and interventions to traumatized students but also to the communities they live in to minimize adverse effects on educational attainment.

Anxiety and Depression from Childhood to Young Adulthood: Trajectories and Risk Factors

This study aimed to (1) evaluate how population levels of anxiety and depression grow and correlate from middle childhood through early adulthood, and (2) determine whether sex, family socioeconomic status, parental education, academic achievement, learning disabilities, or externalizing symptoms predict anxiety and/or depression levels and growth trajectory. We used two longitudinal samples (N = 445, 448) of Portuguese children. Mean depression levels increased from mid-childhood through adolescence before stabilizing in early adulthood and were most strongly predicted by academic achievement and learning disabilities. Mean anxiety levels increased until adolescence before decreasing across early adulthood and were most strongly predicted by academic achievement, learning disabilities, and externalizing symptoms. Quadratic models of growth fit best for both depression and anxiety, and depression and anxiety growth trajectories were strongly correlated. Though anxiety and depression trajectories differ in pattern and predictors, the two are highly interrelated and pathways to comorbid anxiety and depression should be characterized.

The Impact of Adverse Childhood Experiences and Community Violence Exposure on a Sample of Anxious, Treatment-Seeking Children

Screening for adverse childhood experiences (ACEs) can help prevent and reduce adverse outcomes on child development, including increased risk for anxiety disorders. Emerging studies strongly support the inclusion of community-level adversities in ACE screeners to consider diverse contexts and populations. Recent studies suggest that community violence exposure (CVE) may have a distinct impact on youth mental health. Although recent studies have examined the association between ACEs, CVE, and mental health in primary care settings, this association has not been examined on treatment-seeking children in urban mental health settings. The present study employs a mediation model using the PROCESS macro to examine community violence exposure mediating the effect on the association between ACEs and somatic symptoms (SS) on a sample of anxious treatment-seeking children. A total of 98 participants (Mage = 11.7, SD = 3.79, 51.6% males, 54.1% ethnic minority children) who sought services at a specialized anxiety clinic completed self-report measures. Results indicated that exposure to ACEs is associated with endorsement of somatic symptoms as a result of reporting hearing, witnessing, or experiencing CVE. Evidence of mediation was found in a statistically significant indirect effect of ACEs on SS through CREV (Effect = .17, 95% CI = .069-.294). These findings support recent evidence that CVE is a distinct ACE as it contributes to toxic stress similar to individual-level ACEs. The use of a comprehensive ACE screening that includes CVE is warranted, particularly when working with culturally and socioeconomically diverse populations, as it would better capture a broader range of adversities across demographic groups.

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.

Internalizing symptoms among Taiwanese adolescents in poverty: Longitudinal influences of neighborhood, family, and school

INTRODUCTION

Identifying specific contextual factors that contribute to the development of internalizing symptoms in adolescents in poverty is critical for prevention. This study examined the longitudinal effects of neighborhood disadvantage, family cohesion, and teacher-student relationship on adolescent internalizing symptoms from economically disadvantaged families.

METHODS

Participants were 1404 Taiwanese adolescents (49% female) in the nationally representative Taiwan database of children and youth in poverty. Youth were enrolled in the seventh, eighth, or ninth grades (Time 1; M_age  = 14.85, SD = 0.95) and completed biennial follow-up assessments 2 (Time 2; M_age  = 16.47, SD = 0.74) and 4 years after baseline (Time 3; M_age  = 18.21, SD = 0.70). Latent growth models examined longitudinal associations between contextual factors and internalizing symptoms over time.

RESULTS

Adolescents reported declines in neighborhood disadvantage and teacher-student relationship but increases in family cohesion over the 4 years. At baseline, greater neighborhood disadvantage was associated with higher levels of internalizing symptoms, whereas higher family cohesion was associated with lower levels of internalizing symptoms. Over time, an increase in family cohesion was associated with a decrease in internalizing symptoms.

CONCLUSION

This study provides empirical support that family cohesion plays a critical role in shaping the development of adolescent internalizing symptoms despite poverty. There was an increase in family cohesion from early to late adolescence among Taiwanese adolescents in poverty and such change was correlated with decreases in youth internalizing symptoms. Family cohesion may be a key target of prevention programs aiming to reduce internalizing symptoms for youth in poverty.

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.

Predicting exercise behaviors and intentions of Taiwanese urban high school students using the theory of planned behavior

PURPOSE

This study applied the Theory of Planned Behavior to predict exercise behaviors and intentions of teenagers and analyzed sex differences.

DESIGN AND METHODS

A prospective study design was employed to survey tenth-grade students in Taipei, Taiwan. The 951 participants reported their exercise attitudes, subjective norms, perceived behavioral control (PBC), and intentions, and their exercise behaviors were tracked 6 months later.

RESULTS

Results revealed that 22.1% of all students and more male students than female students exercised for ≥30 min/day on 5 or more days/week. Hierarchical multiple regression analyses demonstrated that intentions, PBC, attitudes, and subjective norms explained 32.5% of the variation in exercise behavior (p < .001). Intentions, attitudes, and PBC were related to exercise behavior regardless of sex. Attitudes, subjective norms, and PBC explained 67.0% of the variation in intentions (p < .001). Attitudes and PBC were related to intentions regardless of sex.

CONCLUSIONS

The findings support that the main constructs of the Theory of Planned Behavior can effectively predict regular exercise intentions and behaviors among adolescents.

PRACTICE IMPLICATIONS

The results can serve as a reference for nurses and other healthcare professionals when formulating effective strategies to encourage adolescents to engage in exercise practices.

Sex differences in mental health among older adults: investigating time trends and possible risk groups with regard to age, educational level and ethnicity

OBJECTIVES

Older women report lower mental health compared to men, yet little is known about the nature of this sex difference. Therefore, this study investigates time trends and possible risk groups.

METHOD

Data from the Doetinchem Cohort Study (DCS) and the Longitudinal Aging Study Amsterdam (LASA) were used. General mental health was assessed every 5 years, from 1995 to 1998 onwards (DCS, n = 1412, 20-year follow-up, baseline age 55-64 years). Depressive and anxiety symptoms were assessed for two birth cohorts, from 1992/1993 onwards (LASA cohort 1, n = 967, 24-year follow-up, age 55-65 years,) and 2002/2003 onwards (LASA cohort 2, n = 1002, 12-year follow-up, age 55-65 years) with follow-up measurements every 3-4 years.

RESULTS

Mixed model analyses showed that older women had a worse general mental health (-6.95; -8.36 to 5.53; range 0-100, ∼10% lower), more depressive symptoms (2.09; 1.53-2.63; range 0-60, ∼30% more) and more anxiety symptoms (0.86; 0.54-1.18; range 0-11, ∼30% more) compared to men. These sex differences remained stable until the age of 75 years, where after they decreased due to an accelerated decline in mental health for men compared to women. Sex differences and their course by age were consistent over successive birth cohorts, educational levels and ethnic groups (Caucasian vs. Turkish/Moroccan).

CONCLUSION

There is a consistent female disadvantage in mental health across different sociodemographic groups and over decennia (1992 vs. 2002) with no specific risk groups.

mHealth: Potentials and Risks for Addressing Mental Health and Well-Being Issues Among Nepali Adolescents

Adolescents are slowly being recognized as a generation, worldwide, that may require different policy approaches to improve staggering statistics on their failing well-being, including mental health. By providing the support to allow the next generation to achieve better mental health outcomes, they are going to be more economically successful and the future economic growth of nations can be better assured. Adoption of mobile-based health interventions (e.g., mHealth) has garnered a lot of attention toward this end. While mHealth interventions are growing in popularity, many researchers/policy-makers appear to have neglected assessing potential (indirect) costs/negative consequences from their use. Evidence from the developed world shows strong associations between extensive cell phone use and negative mental health outcomes, but similar research is minimal in developing world contexts. Additionally, the bulk of work on the outcomes of mobile phone use is studied using a unidirectional approach with blinders to front-end motivations. Using primary data from a large-scale, school-based survey of older adolescents in southwestern Nepal (N = 539), this work investigates such a tension between mobile/smartphone usage as a true mobile health (mHealth) opportunity in Nepal or as a potential problem, introducing additional deleterious well-being effects from over-use. Founded in Basic Psychological Needs Theory (BPNT), robust results of analyses using full structural modeling approaches (and traditional regression-based sensitivity analyses) indicate support for the BPNT framework in explaining statistically significant positive associations between bullying and anxiety, as well as, negative associations between bullying and grit, including evidence to support the mediating role of problematic mobile phone use in these relationships. More than 56% of the sample showed indicators of mild to moderate anxiety and over 10% claim experiences of bullying, coupled with over 75% of the sample scoring above the midline of a problematic mobile phone use scale, all of which motivates the relevance of our findings. Potential policy implications of these findings, and mention of other intriguing avenues for future work are further discussed.

Executive Control in Early Childhood as an Antecedent of Adolescent Problem Behaviors: A Longitudinal Study with Performance-based Measures of Early Childhood Cognitive Processes

Identifying childhood cognitive processes that predict adolescent problem behaviors can help guide understanding and prevention of these behaviors. In a community sample of 313 youth recruited in a small Midwestern city between 2006 and 2012 (49% male, 64% European American), executive control and foundational cognitive abilities were assessed at age 5 in a lab setting with performance-based measures. In adolescence, youth provided self-report of problem behaviors in surveys administered annually between ages 14 and 16. Executive control was negatively associated with externalizing behavior problems and adolescents getting in trouble at school, accounting for foundational cognitive abilities and family background covariates. Executive control had negative, but nonsignificant, associations with internalizing problems and substance use initiation. The findings point to deficits in executive control as a childhood risk factor for later problems and a potential target for preventive interventions.

Parental hostility predicts reduced cortical thickness in males

Although impacts of negative parenting on children's brain development are well-documented, little is known about how these associations may differ for males and females in childhood. We examined interactions between child sex and early and concurrent parental hostility on children's cortical thickness and surface area. Participants included 63 children (50.8% female) assessed during early childhood (Wave 1: M age = 4.23 years, SD = 0.84) and again three years later (Wave 2: M age = 7.19 years, SD = 0.89) using an observational parent-child interaction task. At Wave 2, children completed a structural MRI scan. Analyses focused on regions of interest. After correcting for multiple comparisons, Wave 1 parental hostility predicted males' reduced thickness in middle frontal and fusiform cortices, and Wave 2 parental hostility was concurrently associated with males' reduced thickness in the middle frontal cortex. Interactions between sex and parenting on children's surface area did not survive corrections for multiple comparisons. Our findings provide support for a male-specific neural vulnerability of hostile parenting across development. Results have important implications for uncovering neural pathways to sex-differences in psychopathology, learning, and cognitive disabilities.

Children and adolescents attempting to participate in a worldwide online depression screener

Depression rates are increasing among minors. Internet is central to the lives of many minors, and many of them look online for depression information. This report describes minors who attempted to screen themselves for depression in a worldwide online study. Google Ads were used to recruit individuals to a multilingual depression screening study that was meant to target and recruit adults. Of 158,170 individuals accessing the site, 30,396 (19.22%) were minors from 190 countries. Proportions of minors varied considerably between different cultures. Given youth's interest in depression information, online services to ethically and effectively address youth depression are needed.

Predicting Exercise Intentions and Behaviors of Taiwanese Children in a Longitudinal Sample

PURPOSE

The primary purpose of this study was to investigate changes in exercise intentions and behaviors among children across time. Then, we investigated how determinants in the Theory of Planned Behavior (TPB) predicted exercise intentions and behaviors, and explored if demographic predictors contributed to predicting behaviors.

DESIGN AND METHODS

A three-wave, 12-month longitudinal study was conducted. A proportional stratified random sampling method was adopted, and 1997 children from 11 elementary schools in Taipei City were recruited. Numbers of participants were 1074, 1064, and 995 at times 1, 2, and 3, respectively.

RESULTS

Children's exercise intentions and behaviors significantly changed (both p < .05) during a 6-month interval. Attitudes, subjective norms, and perceived behavioral control (PBC) at time 1 could respectively explain 51.0% and 17.1% of the variance in time 1 and 2 intentions (F_{(3, 1068)} = 372.20, F_{(3, 1059)} = 73.92, both p < .001). PBC was the strongest predictor of the intention to exercise. Intentions were the immediate determinant of exercise behaviors. PBC not only indirectly affected exercise behaviors through intentions but also directly affected exercise behaviors. Gender and sports club participation directly affected children's exercise behaviors.

CONCLUSIONS

The findings support the TPB model being suitable for use in longitudinal studies; its core constructs significantly predicted children's exercise intentions and behaviors.

PRACTICE IMPLICATIONS

This study highlights that clinical practitioners and school nurses working with children can help youth engage in regular exercise by enhancing their intentions and perceived behavioral control, and cultivating positive attitudes and subjective norms when planning exercise intervention programs.

Depression and Anxiety Symptoms in Female Adolescents: Relations with Parental Psychopathology and Parenting Behavior

Parental psychopathology and parenting behavior are known to be related to adolescents depression and anxiety, but unique roles of mothers and fathers are not clear. Our aim was to examine the relation of maternal and paternal psychopathology, emotional support, and respect for autonomy, and their interaction to depression and anxiety symptoms in adolescents. In total, 142 female adolescents participated, together with 138 mothers and 113 fathers. Data were analyzed using latent growth curve modeling. Paternal emotional support was negatively related to adolescent baseline level of depression and anxiety symptoms. Further, we found that there was a positive association between respect for autonomy and depression symptoms in adolescents for higher levels of paternal symptoms of psychological problems.

Impact of parent-child relationship and sex on trajectories of children internalizing symptoms

INTRODUCTION

Parenting and parental-child relationship may lead children to develop behavior disorders that can affect many aspects of their later life. This study aimed to examine the impact of parent-child relationship and sex on the development of internalizing symptoms in children.

METHODS

Childhood and Adolescent Behaviors in Long-term Evolution (CABLE) is a longitudinal healthy-lifestyle research for which 18 elementary schools were randomly selected respectively in Taipei and Hsinchu in Taiwan. Data on sex, parent-child relations, and internalizing symptoms from four waves of follow-up were analyzed: 2003 (9 year olds), 2006 (12 year olds), 2009 (15 year olds) and 2012 (18 year olds). A latent growth model was used to examine the impact of parental-child relationship and sex on the trajectory of children's internalizing symptoms.

RESULTS

Results show that internalizing symptoms is more severe (β = 0.21, p < 0.01) and their growth rate faster (β = 0.15, p < 0.01) in girls than in boys. Results from latent growth model show that parent-child relationship is negatively related to the internalizing symptoms intercept (β = -0.59, p < 0.01) and is positively related to the internalizing symptoms slope (β = 0.18, p < 0.01).

LIMITATIONS

Self-reported measures were used. Parent-child relationship was only provided at 2003.

CONCLUSION

The findings suggest that girls are more susceptible to internalizing symptoms in puberty, and better parent-child relationship can have a protective influence although the protective impact reduced through time. Health professionals should be sensitive to sex, family functioning and provide positive parenting programs for children at risk for internalizing symptoms.

Measuring depressive symptoms during adolescence: what is the role of gender?

AIMS

The higher prevalence of depressive symptoms among females is well recognised but the reasons for this gender difference are not fully understood. There is growing evidence that current diagnostic criteria and instruments used to assess depression are less sensitive to depression in men, but studies about this issue among adolescents are scarce, especially in Latin countries. Our aim was to assess sex differences in the intensity of depressive symptoms, measured using the Beck Depression Inventory second edition (BDI-II), among Portuguese adolescents, at 13 and 17 years of age.

METHODS

Urban adolescents born in 1990 and enrolled in schools of Porto, Portugal, in 2003-2004 (EPITeen study) completed the BDI-II at 13 and 17 years of age. The final sample included 1988 (52.2% girls) and 2131 (53.0% girls) adolescents at 13 and 17 years, respectively. Sex differences in the frequency of endorsing the statements on the 21 items of the BDI-II were examined using the χ2 test and effect sizes were estimated (Cohen's w). To examine whether responses were linked systematically to sex, we used a differential item functioning (DIF), based on the logistic regression approach. Option characteristic curves were estimated for items with differential endorsement and a new BDI-II score was computed excluding those items.

RESULTS

Girls and boys at the same level of depression expressed similar severity ratings for most of the depressive symptoms. We had four items with DIF at 13 and 17 years of age. At 13 years, two items provided lower scores (sadness and crying items) and two higher scores (punishment feelings and loss of interest in sex items) among boys, comparing with equally depressed girls. At 17 years, the four items with DIF provided lower scores among boys (sadness, crying, self-dislike and tiredness or fatigue items). After excluding these items the prevalence of depression remained higher among girls but at 17 years the difference between sexes was attenuated.

CONCLUSIONS

Sex differences were found in the functioning of the BDI-II, more relevant at 17 years of age, which may lead to an overestimation of symptoms among girls as well as to lower reported rates of depression among boys. For a higher diagnostic accuracy it is important that the criteria and instruments used to assess depression adequately reflect female and male common symptoms and experiences of depression.

Prospective predictors of first-onset depressive disorders in adolescent females with anxiety disorders

BACKGROUND

Anxious youth are at increased risk for later depressive disorders, but not all anxious youth develop depression. Sequential comorbidity models emphasize shared risk factors and anxiety sequelae, but some anxious youth who later develop depression may have risk factors that are relatively specific to depression, in addition to a liability to anxiety. We examined several variables that appear relatively specific to risk for depression-the personality traits of low positive affectivity and high sadness, and an electrophysiological measure of blunted response to reward - in predicting first-onset depressive disorders and depressive symptoms in clinically anxious adolescent girls.

METHODS

A sample of 114 adolescents with baseline anxiety disorders completed personality and psychopathology measures, psychophysiology tasks, and diagnostic interviews. Interviews and a measure of depressive symptoms were re-administered over 27 months.

RESULTS

After controlling for baseline depressive symptoms, blunted reward sensitivity uniquely predicted first-onset depressive disorders and depressive symptoms 27 months later. Post-hoc analyses indicated that blunted reward sensitivity only predicted first-onset depressive disorders and depressive symptoms in girls with high social anxiety symptoms.

LIMITATIONS

Analyses were unable to account for concurrent anxiety symptoms and disorders.

CONCLUSIONS

The depression-specific risk factor, blunted reward sensitivity, may comprise one pathway to subsequent depressive disorders and symptoms in anxious youth and indicate which anxious youth need intervention to prevent later depression, particularly in socially anxious girls.

Outcomes of a Randomized Controlled Trial on the Effectiveness of Depression and Anxiety Prevention for Adolescents with a High Familial Risk

A randomized controlled trail was conducted to examine the effectiveness of a depression and anxiety prevention program ‘Een Sprong Vooruit’ (A Leap Forward) among adolescent girls with a high familial risk (N = 142). The results showed neither effects of the prevention program directly after the intervention, nor at 6 or 12 months follow-up on depression and anxiety symptoms. Further, latent growth curve modeling (LGCM) was used to examine whether the growth functions for the intervention and the control condition were different. The slope representing the change in depression symptoms was not significantly different between the intervention and the control condition. For anxiety symptoms, the difference between slopes was also not significant. Based on these results, we suggested that these high-risk adolescent girls might benefit more from a more intensive prevention program.

Emergence of Depressive Symptoms from Kindergarten to Sixth Grade

This study documents the emergence of symptoms of anxiety and depression in a community sample of school-age children and describes the temporal progression of symptoms leading to depressive episodes. Caregivers of 468 seventh graders reported retrospectively the manifestation of 14 symptoms of depression and anxiety in their children from kindergarten through sixth grade. The sample was balanced by sex and reflected the racial and economic diversity of the urban school district. Childhood period prevalence was calculated for each symptom, and discrete time survival analyses compared likelihoods of early symptom emergence in children who did and did not meet diagnostic criteria for major depressive disorder (MDD) by ninth grade. Symptom prevalence ranged between 20% (excessive guilt) and 50% (concentration problems) during the elementary school years. The 4-year period prevalence of MDD was 8.9%, 95% confidence interval [6.5%, 12.1%]. Low energy, excessive worry, excessive guilt, anhedonia, social withdrawal, and sadness or depressed mood were each associated with a significantly higher likelihood of onset of MDD. Compared to girls, boys were more likely to exhibit sad mood, fatigue, and trouble concentrating. Children who later met criteria for MDD demonstrated a significantly higher likelihood of showing core features of depressive and anxiety disorders during their elementary school years. The findings underscore the importance of recognizing early signs and developing interventions to help children manage early symptoms and prevent later psychiatric illness.

Implication of galanin gene rs948854 polymorphism in depressive symptoms in adolescents

Genetic, social, and environmental conditions contribute to the development of depression, but the pathophysiological mechanisms are still unclear. Data accumulated in recent years provide significant evidence for a direct role of galanin (GAL). This study aimed to investigate the relation between SNPs in the galaninergic system and depressive symptoms in adolescents. A total of112 adolescents aged 10-18years participated in this study. The Children Depression Inventory (CDI) was used to evaluate depressive symptoms. The effects of rs948854 and rs4432027 SNPs, both located within the promoter region of the GAL gene, rs11665337 in the GALR1 receptor, and rs8836 in the GALR2 receptor on depressive symptoms were examined. The results indicated that 30.4% of the participants had depression. We found that girls were significantly more likely to be depressive than boys. Furthermore, rs948854 minor (G) allele was associated with depressive symptoms. Adolescents carrying the GG and AG genotype for the A/G (rs948854) SNP showed higher CDI scores than those carrying homozygous AA. The binomial logistic regression analysis revealed that adolescents carrying the GG genotype at SNP rs948854 had a higher likelihood of being depressive than adolescents carrying the AA or AG genotypes (P=0.033). Moreover, individuals whose mothers had a positive history for depression and who were sedentary were more likely to display depressive symptoms (P=0.013 and P=0.032, respectively). In conclusion, the SNP rs948854 in the GAL gene seems to be involved in the modulation of depressive state, especially in individuals with GG genotype.

Gender differences in factors associated with smartphone addiction: a cross-sectional study among medical college students

BACKGROUND

Smartphones are becoming increasingly indispensable in everyday life for most undergraduates in China, and this has been associated with problematic use or addiction. The aim of the current study was to investigate the prevalence of smartphone addiction and the associated factors in male and female undergraduates.

METHODS

This cross-sectional study was conducted in 2016 and included 1441 undergraduate students at Wannan Medical College, China. The Smartphone Addiction Scale short version (SAS-SV) was used to assess smartphone addiction among the students, using accepted cut-offs. Participants' demographic, smartphone usage, and psycho-behavioral data were collected. Multivariate logistic regression models were used to seek associations between smartphone addiction and independent variables among the males and females, separately.

RESULTS

The prevalence of smartphone addiction among participants was 29.8% (30.3% in males and 29.3% in females). Factors associated with smartphone addiction in male students were use of game apps, anxiety, and poor sleep quality. Significant factors for female undergraduates were use of multimedia applications, use of social networking services, depression, anxiety, and poor sleep quality.

CONCLUSIONS

Smartphone addiction was common among the medical college students investigated. This study identified associations between smartphone usage, psycho-behavioral factors, and smartphone addiction, and the associations differed between males and females. These results suggest the need for interventions to reduce smartphone addiction among undergraduate students.

Comparing depressive symptoms in teenage boys and girls

Introduction

Symptoms of depression vary between the males and females. Depressed men show behaviors such as irritability, restlessness, difficulty in concentrating, and instead of the usual behaviors. Sleep disturbance is a common symptom in depressed men. Men are less likely to go to doctors and unconsciously show other behaviors such as anger instead of the sadness. It seems that considering depression as "feminine" is a great injustice toward male patients whom their illness will not be diagnosed nor treated.

The sample consisted of 191 depressed adolescents, 108 males and 83 females aged 13-19 years old. Data collected for 10 years from 2005 to 2015 and their depressive symptoms were evaluated by the Beck Depression Inventory-Second Edition.

Results

Depressed girls felt sadness, guilt, punishment, worthlessness, low energy and fatigue, or more asthenia, whereas depressed boys have symptoms such as irritability, depression, suicidal thoughts, or desires to reduce their pleasure. The results of t-test showed that the difference between the total scores of boys and girls with depressive disorder (16.93) is significant at 0.001. F values for feeling sad (58.13), hatred of self (12.38), suicidal thoughts or desires (12.97), restlessness (17.35), and irritability (46. 41) were significant in the 0.001.

Conclusion

Experiencing depression in boys and girls according to the role of gender was different. Gender can have an effective role in showing depression symptoms in adolescents.

Social support seeking and early adolescent depression and anxiety symptoms: The moderating role of rumination

This study examined how social support seeking and rumination interacted to predict depression and anxiety symptoms six months later in early adolescents (N = 118; 11 - 14 yrs at baseline). We expected social support seeking would be more helpful for adolescents engaging in low rather than high levels of rumination. Adolescents self-reported on all measures at baseline, and on depression and anxiety symptoms six months later. Social support seeking predicted fewer symptoms of depression and anxiety at low rumination levels, but lost its adaptive effects as rumination increased. For depression symptoms, social support seeking led to more symptoms at high rumination levels. Results were stronger for emotion-focused than problem-focused support seeking, and for depression compared to anxiety symptoms. These findings suggest that cognitive risk factors like rumination may explain some inconsistencies in previous social support literature, and highlight the importance of a nuanced approach to studying social support seeking.

Prevalence and factors associated with depression symptoms among school-going adolescents in Central Uganda

BACKGROUND

Depression in adolescents constitutes a global public health concern. However, data on its prevalence and associated factors are limited in low income countries like Uganda.

METHODS

Using a cross-sectional descriptive study design, 519 adolescent students in 4 secondary schools in Mukono district, Uganda, were randomly selected after meeting study criteria. The 4 school types were: boarding mixed (boys and girls) school; day mixed school; girls' only boarding school; and, boys' only boarding school. The 519 participants filled out standardized questionnaires regarding their socio-demographic characteristics and health history. They were then screened for depression using the Children Depression Inventory (CDI) and those with a cut-off of 19 were administered the Mini International Neuro-Psychiatric Interview for Children and Adolescents 2.0 (MINI-KID), to ascertain the Diagnostic and Statistical Manual of Mental Disorders, 4th Edition (DSM IV) diagnostic types of depression and any co morbidity. Logistic regression analyses were used to assess factors associated with significant depression symptoms (a score of 19 or more on the CDI).

RESULTS

There were 301 (58 %) boys and 218 (42 %) girls with age range 14-16 years and a mean age of 16 years (SD 2.18). Of 519 participants screened with the CDI, 109 (21 %) had significant depression symptoms. Of the 109 participants with significant depression symptoms, only 74 were evaluated with the MINI-KID and of these, 8 (11 %) met criteria for major depression and 6 (8 %) met criteria for dysthymia. Therefore, among participants that were assessed with both the CDI and the MINI-KID (n = 484), the prevalence of depressive disorders was 2.9 %. In this sample, 15 (3.1 %) reported current suicidal ideation. In the logistic regression analyses, significant depression symptoms were associated with single-sex schools, loss of parents and alcohol consumption.

LIMITATIONS

This is a cross-sectional study therefore, causal relationships are difficult to establish. Limited resources and the lack of collateral information precluded the assessment of a number of potential factors that could be associated with adolescent depression. The MINI-KID was administered to only 74 out of 109 students who scored ≥19 on the CDI since 35 students could not be traced again due to limited resources at the time.

CONCLUSIONS

Significant depression symptoms are prevalent among school-going adolescents and may progress to full-blown depressive disorders. Culturally sensitive psychological interventions to prevent and treat depression among school-going adolescents are urgently needed.

Error-related negativity (ERN) and sustained threat: Conceptual framework and empirical evaluation in an adolescent sample

The error-related negativity (ERN) currently appears as a physiological measure in relation to three Research Domain Criteria (RDoC) constructs: Cognitive Control, Sustained Threat, and Reward Learning. We propose a conceptual model in which variance in the ERN reflects individual differences in the degree to which errors are evaluated as threatening. We also discuss evidence for the placement of the ERN in the "Sustained Threat" construct, as well as evidence that the ERN may more specifically reflect sensitivity to endogenous threat. Following this, we present data from a sample of 515 adolescent females demonstrating a larger ERN in relation to self-reported checking behaviors, but only in older adolescents, suggesting that sensitivity to internal threat and the ERN-checking relationship may follow a developmental course as adolescents develop behavioral control. In contrast, depressive symptoms were linked to a smaller ERN, and this association was invariant with respect to age. Collectively, these data suggest that the magnitude of the ERN is sensitive both to specific anxiety-related processes and depression, in opposing directions that may reflect variation in internal threat sensitivity. We discuss directions for future research, as well as ways in which findings for the ERN complement and challenge aspects of the current RDoC matrix.

Emotional Awareness: A Transdiagnostic Predictor of Depression and Anxiety for Children and Adolescents

Research increasingly suggests that low emotional awareness may be associated with symptoms of depression and anxiety among children and adolescents. However, because most studies have been cross-sectional, it has remained unclear whether low emotional awareness predicts subsequent internalizing symptoms. The current study used longitudinal data to examine the role of emotional awareness as a transdiagnostic predictor of subsequent symptoms of depression and anxiety. Participants were 204 youth (86 boys and 118 girls) ages 7-16 who completed self-report measures of emotional awareness, depressive symptoms, and anxiety symptoms at baseline, as well as measures of depression and anxiety symptoms every 3 months for a year. Results from hierarchical mixed effects modeling indicated that low baseline emotional awareness predicted both depressive and anxiety symptoms across a 1-year period. These findings suggest that emotional awareness may constitute a transdiagnostic factor, predicting symptoms of both depression and anxiety, and that emotional awareness training may be a beneficial component of treatment and prevention programs for youth depression and anxiety.

A qualitative study of the prodrome to first-episode major depressive disorder in adolescents

BACKGROUND

Currently, we lack a clear picture of the evolution of major depressive disorder (MDD) in adolescents. The period of disturbance preceding MDD can be conceptualised as the prodrome. The aim of the study was to explore the prodrome of first-episode MDD retrospectively in a group of help-seeking adolescents using qualitative methodologies.

SAMPLING AND METHODS

Consecutively referred adolescents (15-18 years of age) with first-episode MDD were recruited for this study from Orygen Youth Health, Melbourne, Vic., Australia. After using quantitative methodologies to confirm the index episode of MDD and measure the extent of recovery, the prodrome was investigated in depth using qualitative techniques.

RESULTS

Twenty-nine adolescents (20 females and 9 males) and 7 informants (6 mothers and 1 grandmother) participated. All 29 participants had a prodrome of varying lengths (between 6 days and 4 years). The most noticeable symptoms initially were perplexity and confusion and, thereafter, sadness and irritability. A common pattern was a reduction in their ability to fulfil their role accompanied by guilt, self-blame and reduced self-esteem. Around half of the participants had increased thoughts of suicide and increased anxiety. There were gender differences in the patterns of symptoms noticed, with males more commonly noticing a change in how they related to the world and females more commonly noticing a change in the way that they related to others. All informants noticed a prodrome of varying lengths; in 2 cases longer, in 2 cases shorter and in 3 cases around the same time period as that noticed by the participant. The changes most commonly noticed by informants were sadness, upset, irritability and reduced self-esteem. The symptoms were fewer in number and sometimes varied from those noticed by the adolescents themselves.

CONCLUSIONS

Whilst we recognise that this study is vulnerable to autobiographical bias, we took all reasonable measures to minimise this. Symptoms not included in the diagnostic criteria for depression were the earliest changes noticed by the adolescents themselves and are, therefore, potentially important in informing prevention strategies, as is the finding that there are gender differences in the patterns of changes noticed. In addition, parents may provide an additional avenue to help seeking.

Analysis of the interplay between depression, anxiety, and psychological resources in adolescence using self-report measures

OBJECTIVE

Following recent literature which stresses the importance of broadening the conceptualization of mental functioning in youth, this paper aims to investigate structural relations between indicators of anxiety, depressive symptoms, and psychological resources in non-referred Italian adolescents, as captured by the Strengths and Difficulties Questionnaire (SDQ; Goodman 2001 ), the Spence Children's Anxiety Scale (SCAS; Spence 1998 ) and the Children Depression Inventory (CDI; Kovacs 1992 ).

METHODS

A hierarchical model which considers both the interplays and overlaps between these instruments is tested by means of Confirmatory Factor Analysis, in order to explore the possibility to use the three tools within a meaningful screening battery. First, validity and reliability of SDQ, SCAS, and CDI is successfully controlled thanks to three appropriate preliminary studies, an evidence not already acquired in the Italian context for the adolescent population. Then, the focal study devises and tests a model that merges indicators of the SDQ, SCAS, and CDI scales into four correlated factors, that is, Psychological Resources, Externalized behavior problems, Internalized Fear and Internalized Anxious Misery.

CONCLUSIONS

Overall, findings corroborate the combined use of SDQ, SCAS, and CDI as a screening battery for the assessment of mental functioning in youth adopting a dimensional rather than a categorical approach.

[The temporal relationship between anxiety and depression during the school transition between primary and high-school]

Depression and anxiety are among the most prevalent disorders in the adolescent population. An increase of the prevalence of these disorders is taking place during adolescence, this developmental period being experienced in synchronicity with the high school transition. Also, some studies suggested the existence of a developmental trend between the onset of anxiety and depression. This longitudinal study explored the temporal relationship between anxiety and depression during the transition from primary to high school.

GOALS

first, this study examined whether the presence of anxiety in grade 6 (Time 1) increases the risk of depression in grade 8 (Time 2). Then a subgroup of comorbid students, who presented anxiety and depression, was compared with a subgroup of anxious ones on the presence of cognitive distortions. It was assessed whether cognitive distortions in the anxious group in Time 1 influenced the development of comorbidity between anxiety and depression in Time 2.

METHOD

146 students from 12 public schools, 62 girls and 84 boys (mean = 11.22 years) participated in this study. This sub sample was drowned from a larger sample of 499 students, in a 9 years longitudinal study (2003-2012). Participants completed the questionnaire and were met for an interview at the beginning of each school year. Parents consent was obtained. In Time 1, students were divided into two subgroups, anxious and non-anxious students. At time 2, two subgroups of students were constituted, either anxious or comorbid anxious and depressed students. Depression was controlled at time 1.The Dominic Interactive for Adolescents (Valla, 2000) was used to measure the presence of anxiety and depression. The correlation (.34 to .62) between the three anxiety scales (separation anxiety, generalized anxiety and phobia) allowed to create an unique anxiety score. Cognitive distortions (related to dependence, achievement and self control) were measured by the Dysfunctional Attitudes Scale (Weisseman & Beck, 1978).

RESULTS

The hierarchical log linear analyse revealed a tendency between the presence of anxiety in Time 1 and the development of depression in Time 2, only for girls (p=.08), so that 25% of anxious girls at Time 1 became depressive at Time 2, compare to 0% of non anxious girls. For boys, whether anxiety is present or not, the two subgroups presented the same risk to develop depression. Then, results of a Manova analysis revealed that anxious students at time 1 already adopted cognitive distortions related to dependency and to achievement, usually associated with depression. At time 2, the result of the Manova revealed that comorbid students presented more cognitive distortions related to dependency then the anxious students. However, non significant results were found for the longitudinal analyse, which did not supported the existence of a predicting link between the presence of depressogenous cognitive distortions at Time 1 in the anxious subgroup of students and the emergence of comorbidity at Time 2.

CONCLUSION

The results of the present study testified the importance to prevent depression, especially for anxious school girls. Anxiety seems to have a different role for girls and boys. A trend was observed between the presence of an anxiety disorder in Grade 6 and the development of a depressive disorder 2 years later, among girls only. This result raises the importance to understand the role of anxiety in girls to reduce their risk to develop a depressive disorder. Our results also showed that anxious students in grade 6, already presented cognitive distortions related to dependency and achievement which are associated with depression while comorbid students in the second year of high school presented more cognitive distortions related to dependency only, when they were compared with the anxious group.

Effectiveness of depression and anxiety prevention in adolescents with high familial risk: study protocol for a randomized controlled trial

BACKGROUND

Depression and anxiety disorders during adolescence can have detrimental consequences. Both disorders are related to negative outcome in various areas during adolescence and are also predictive of depression and anxiety disorders later in life. Especially parental psychopathology and being female are risk factors that increase the probability of developing one of these disorders during adolescence. Research has shown that prevention programs have promising results, especially for adolescents who have these risk factors. Therefore, in this study, we will focus on the effectiveness of a prevention program 'A jump forward' that has been developed for adolescent girls with a familial risk of depression and/or anxiety.

METHODS/DESIGN

We designed a randomized controlled trial to test the effectiveness of an indicated and selective prevention program aimed at depression and anxiety in adolescent girls. Adolescents aged between 11 and 15 years old with depressive and/or anxiety symptoms and with parents who show indicators of parental psychopathology will be randomly assigned to the experimental (N = 80) or control groups (N = 80). Participants in the experimental group will follow a preventive intervention, consisting of six sessions of 90 minutes each. All participants will complete baseline, intervention phase 1 (after session 2), intervention phase 2 (after session 4), post-intervention, 6 month follow-up, and 12 month follow-up assessments. Furthermore, parents will be asked to complete assessments at baseline, post-intervention, and 12-month follow-up. Primary outcome will be depressive symptoms. Secondary outcomes will be anxiety symptoms, suicidal ideation, response style, negative cognitive errors, parental emotional support and parental control, parental psychopathology, parenting stress and adolescents' depression and anxiety symptoms according to the parents.

DISCUSSION

This paper described the study designed to evaluate a program for preventing depression and/or anxiety in high-risk adolescents over a 12-month follow-up period. If the program showed to be effective in reducing symptoms of depression and anxiety and preventing adolescents from developing clinical levels of these disorders, our results would be relevant to practice. Thus, the intervention could be used on a large scale. Moreover, this study aims to contribute to the evidence-based prevention of depression and anxiety of adolescents.

Depressive symptoms and its associated factors in 13-year-old urban adolescents

The available estimates reveal that 20-50% of adolescents report depressive symptoms, being one of the most prevalent health problems in adolescence. The aim of this study was to assess the prevalence of depressive symptoms in a community sample of 13-year-old adolescents and identify associated features. Thirteen year-old adolescents attending private and public schools in Porto (n = 1,988, 52.2% females) were evaluated from October 2003 to June 2004 and completed a questionnaire including health behaviors and the Beck Depression Inventory II. A questionnaire on parents' socio-demographics and clinical characteristics was sent home. Data were analyzed separately by sex. Odds ratios (ORs) and 95% confidence intervals (CIs) were estimated using logistic regression. The prevalence of depressive symptoms was 18.8% in girls and 7.6% in boys (p < 0.001). Boys with a family history of depression and girls with smoking habits had a significantly increased risk of depressive symptoms (OR = 2.18, 95%CI 1.00-4.71; OR = 2.34, 95%CI 1.46-3.76). Menarche at an early age significantly increased the risk of depressive symptoms. The characteristics most strongly associated with depressive symptoms were family history of depression among boys, tobacco consumption and an early age at menarche among girls. The high prevalence of depressive symptoms early in adolescence calls for the awareness of public health professionals.

Depression symptom trajectories and associated risk factors among adolescents in Chile

Adolescence is a key period for studying the development of depression, with studies in Europe and North America showing a pattern of elevated risk that begins in early adolescence and continues to increase as adolescents age. Few studies have examined the course of adolescent depression and associated risk factors in low and middle-income countries. This longitudinal cohort study examined depression symptom trajectories and risk factors in a sample of socio-economically disadvantaged adolescents in Chile (n = 2,508). Data were collected over an 18-month period as part of a clinical trial for secondary students aged 12 to 18 (median age 14). Clinical levels of depression were prevalent in this sample at baseline (35% for girls and 28% for boys); yet latent growth models of symptom trajectories revealed a pattern of decreasing symptoms over time. There was evidence of an anxiety-depression developmental pathway for girls, with elevated anxiety levels initially predicting poorer depression outcomes later on. Poor problem-solving skills were associated with initial depression levels but did not predict the course of depressive symptoms. Critically, the declining symptom trajectories raise important methodological issues regarding the effects of repeated assessment in longitudinal studies.

Childhood predictors and mid-adolescent correlates of developmental trajectories of alcohol use among male and female youth

The identification of salient risk factors for alcohol consumption among male and female adolescents is an important topic not only for etiology research but also for designing effective gender-specific alcohol prevention programs for young people. This study examined the extent to which problematic alcohol use trajectories from ages 14 to 18 among male and female youth were related to childhood predictors assessed at age 9 (i.e., impulsivity, academic self-confidence, social problems with peers), socio-demographic variables, and mid-adolescent correlates [i.e., parental use, body mass index (BMI), risky peer context, conduct problems at school, parent-child relationship, somatic complaints]. Data analysis was based on a representative German longitudinal study (1986-1995, n = 1,619, 55 % female). Using growth mixture modeling methodology, associations of childhood predictors and mid-adolescent correlates to distinctive trajectories of alcohol use were examined for males and females separately. For males, a problematic consumption trajectory was associated with poor relationships to parents in adolescence and small community size. For females, low impulsivity during childhood, high BMI, and contact with deviant peers during adolescence predicted problematic as compared to normative alcohol use trajectories. Additionally, high parental alcohol use, low parental educational background, and conduct problems at school during adolescence were common predictors of a problematic alcohol use trajectory in both genders. The results provide insights regarding differences in the gender-typical development of adolescent alcohol use as well as stress the need of gender-specific intervention components along with universal prevention strategies against problematic consumption trajectories.

Do substance use risk personality dimensions predict the onset of substance use in early adolescence? A variable- and person-centered approach

Various studies found personality to be related to substance use, but little attention is paid to the role of personality risk dimensions with regard to an early onset of alcohol, tobacco, and marijuana use. Therefore, the current study used a variable-centered approach to examine whether anxiety sensitivity, hopelessness, sensation seeking, and impulsivity predict the onset of alcohol, tobacco, and marijuana use in early adolescence. Additionally, we adopted a person-centered approach to examine whether different personality subgroups could be identified, and whether these subgroups would be predictive of substance use. For that purpose, longitudinal data of a broader effectiveness study were used from 758 early adolescents (53 % female) aged 11-14 years. Structural equation models showed that hopelessness and sensation seeking were predictive of having ever used alcohol and tobacco. Also, sensation seeking was predictive of marijuana use. Latent profile analyses on the first wave data revealed a three-profile solution for boys (i.e., resilients, internalizers, and externalizers) and a two-profile solution for girls (i.e., resilients and internalizers). In contrast to our expectation, further analyses revealed no significant differences in substance use between the different subprofiles for both boys and girls. The separate personality dimensions thus seem more relevant in predicting the onset of substance use compared to the personality profiles. However, the personality profiles might be informative in explaining more excessive substance use behaviors.

The gap that makes us desperate: paths from language to mental health

Although past research provided some clues about the relation of language use with mental health, the mediatory functions of personality variables in this relationship have been ignored. This research examined the mediatory role of self-concept clarity in the relationship between language use perceived by individuals and mental health indicators including anxiety, depression, and alexithymia. Based on the theoretical framework suggested by Şimşek (2010), two studies sought to test two alternative structural equation models in data from university students in the first study (n = 250) and data from other groups in the second study (n = 331). The first model assumed that the relationship of language use with anxiety, depression, and alexithymia was mediated by self-concept clarity. The second model tested the mediatory role of both anxiety and self-concept clarity in this relationship. The results of the first study showed that the second model fitted better to the data than the first. Consistent with the first study, the results of the second study confirmed that the second model produced better goodness of fit statistics than the first model.

The LAOM Multidimensional Anxiety Scale for Measuring Anxiety in Children and Adolescents

The article introduces a new anxiety scale, called the LAOM (Lestvica anksioznosti za otroke in mladostnike [The anxiety scale for children and adolescents]) for measuring self-reported multidimensional anxiety. The scale has been developed with a special focus on the school setting, using one sample from an elementary school which is representative of fourth- and eighth-grade students in Slovenia ( N = 10,427) and two secondary samples from secondary schools ( N = 1,406; N = 3,253) which are representative of final-year secondary school students in Slovenia. The exploratory (PCA) and confirmatory analyses (CFA) were performed on separate samples for the elementary and the secondary school students. The CFA confirmed that the items on the scale formed three factors which were related to the higher order factor. The structure was stable over different age groups. The scale demonstrated adequate internal consistency and sensitivity. Validity tests are presented in their preliminary forms and will be elaborated upon in future research.

Entering adolescence: resistance to peer influence, risky behavior, and neural changes in emotion reactivity

Adolescence is often described as a period of heightened reactivity to emotions paired with reduced regulatory capacities, a combination suggested to contribute to risk-taking and susceptibility to peer influence during puberty. However, no longitudinal research has definitively linked these behavioral changes to underlying neural development. Here, 38 neurotypical participants underwent two fMRI sessions across the transition from late childhood (10 years) to early adolescence (13 years). Responses to affective facial displays exhibited a combination of general and emotion-specific changes in ventral striatum (VS), ventromedial PFC, amygdala, and temporal pole. Furthermore, VS activity increases correlated with decreases in susceptibility to peer influence and risky behavior. VS and amygdala responses were also significantly more negatively coupled in early adolescence than in late childhood while processing sad and happy versus neutral faces. Together, these results suggest that VS responses to viewing emotions may play a regulatory role that is critical to adolescent interpersonal functioning.

Sex difference in symptomatology of manic episode

OBJECTIVE

Studies addressing sex differences in the symptoms and course of bipolar affective disorder had been investigated across different phase of bipolar affective disorder. There are few studies in manic phase that have reported inconsistent results. Therefore, we investigated sex difference in symptom presentation of manic episode.

METHODS

A total of 150 male and 50 female subjects meeting criteria for manic episode according to International Statistical Classification of Diseases, 10th Revision Diagnostic Criteria for Research, giving written informed consent, were included for the study. Those with comorbid major medical or psychiatric disorders were excluded. All the patients were assessed on Scale for Manic States.

RESULTS

Multivariate analysis of variance using all the items of Scale for Manic Symptoms showed significant sex difference (Pillai's Trace F(20,179) = 5.154, P < .001), with large effect size (η2 = .365). In men, there was significantly higher motor activity, psychosis, grandiosity, contact, and humor, whereas mood lability, depressed mood, guilt, suicide, anxiety, and dress scores were higher in women. Discriminant analysis showed that 84% of men and 72% of women could be correctly classified using the Scale for Manic Symptoms. Stepwise logistic regression analysis showed anxiety, guilt, and dress positively predicted female sex and the model explained 24% to 36% of variance.

CONCLUSION

Symptom presentation of mania differs across sex and a predominance of anxiety and depressive symptoms was found in women, whereas increased psychomotor activity was prevalent in men.

Comorbidity of Anxiety and Depression in Youth: Implications for Treatment and Prevention

The high level of concurrent and sequential comorbidity between anxiety and depression in children and adolescents may result from (a) substantial overlap in both the symptoms and items used to assess these putatively different disorders, (b) common etiological factors (e.g., familial risk, negative affectivity, information processing biases, neural substrates) implicated in the development of each condition, and (c) negative sequelae of anxiety conferring increased risk for the development of depression. Basic research on their various common and unique etiological mechanisms has guided the development of efficacious treatments for anxiety and depressive disorders in youth. Potential processes through which the successful treatment of childhood anxiety might prevent subsequent depression are described.

Clinical characteristics of depression among adolescent females: a cross-sectional study

BACKGROUND

Adolescents rarely seek psychiatric help; they even hesitate to disclose their feelings to their parents. However; the adolescents especially the females experience depressive symptoms more frequently than general population. Do they experience classic depressive symptoms? Are there symptoms specific to this subpopulation?

AIM OF THE STUDY

Through this study, the authors aimed to estimate the prevalence of depressive disorders in Egyptian adolescent female students. They also expected a characteristic profile of symptoms for the adolescent females. However available literature provides no guidance in the description of this profile of symptoms.

METHODS

A number of 602 adolescent females were interviewed, and subjected to General Health Questionnaire (GHQ); Children Depression Inventory (CDI), Structured Clinical Interview for DSM-IV Axis-I Disorders (SCID-I), then Hamilton Rating Scale for Depression (Ham-D). Results were analyzed by the use of SPSS-15.

RESULTS

The study revealed the prevalence of depression in the sample of the study to be 15.3% (measured by CDI), and 13.3% (measured by SCID-I). Fatigue was the most common presenting depressive symptom (81.3%), in addition to other emotional, cognitive and physiological symptoms. Suicidal ideations were the most common suicidal symptoms in depressed adolescent females (20%), with 2.5% serious suicidal attempts.

CONCLUSIONS

The somatic symptoms were by far the most common presenting symptom for female adolescents suffering from depressive disorders. Depressive phenomena including unexplained fatigue, decreased energy, psychomotor changes, lack of concentration, weight changes and suicidal ideations may be the presenting complaints instead of the classic sad mood.
