Psychosomatic complaints at age 15-16 and subsequent depression and anxiety disorders

Abstract Background In recent years, the prevalence of self-reported mental health issues such as psychosomatic complaints has risen among adolescents in several countries, including Sweden. Despite this trend, a gap in the understanding remains regarding the implications of these complaints, including their ability to predict more severe mental health conditions. Depression and anxiety represent common mental health disorders among youth today, significantly affecting daily functioning. In light of this, the current study aims to investigate the association between self-reported psychosomatic complaints at age 15-16 and the likelihood of being diagnosed with depression or anxiety by age 20. Methods Data was drawn from Futura01, a cohort study of Swedish adolescents who attended grade 9 in 2017 (n = 5,225). Information on psychiatric diagnoses was obtained from the Swedish National Patient Register. Psychosomatic complaints were captured through self-reported frequencies of headache, stomach ache, and difficulties falling asleep, which were aggregated into an index (ranging from 3-15). Covariates included sex, parental education, parental country of birth, family type, and prior diagnoses of ADHD, depression, and anxiety. Binary logistic regression analyses were performed. Results The findings show that higher levels of psychosomatic complaints at age 15-16 were prospectively associated with increased odds of being diagnosed with depression (OR = 1.28, 95% CI 1.22-1.34) as well as anxiety (OR = 1.30, 95% CI 1.25-1.35) by age 20, even after adjusting for prior diagnoses and other covariates. Conclusions This study highlights the potential for psychosomatic complaints during adolescence to act as early indicators of future mental health disorders. Recognising the importance of these complaints and implementing public health interventions targeting mental health issues among youth could help improve mental health outcomes in late adolescence and young adulthood. Key messages • Adolescents reporting frequent psychosomatic complaints at age 15-16 were more likely to receive subsequent specialised care due to a depression or anxiety diagnosis in a Swedish sample. • Interventions directed at youth experiencing frequent psychosomatic complaints may have a beneficial impact on their future mental health outcomes.

Abstract MP30: Sugar-Sweetened Beverages, Fruit Juices, and Whole Fruits Throughout Childhood and Adolescence and Glycemic Outcomes in Late Adolescence in Project Viva

Objective: To investigate sex-specific associations of sugar-sweetened beverages (SSBs), 100% fruit juices, and whole fruit intake throughout childhood and adolescence with insulin resistance and glycemic outcomes in late adolescence. Methods: We used data from Project Viva, an ongoing pre-birth cohort from eastern Massachusetts. We evaluated intake of SSBs, 100% fruit juices, and whole fruit at early childhood (median age: 3.1 yrs), mid-childhood (7.6 yrs) and early teen research visits (12.9 yrs) using food frequency questionnaires. We measured fasting blood glucose, insulin and glycated hemoglobin (HbA1c) levels in late adolescence (17.4 yrs). We estimated insulin resistance with the homeostasis model assessment for insulin resistance (HOMA-IR). We computed sex-specific linear regression models to estimate associations of average consumption of SSBs, fruit juice and whole fruit across the 3 childhood-early teen visits with late adolescence HOMA-IR, fasting glucose and HbA1c adjusting for demographics, socioeconomic status, mother BMI, child BMI z-score, and parental history of type 2 diabetes in early childhood (model 1), and additionally for lifestyle habits and diet quality in early childhood (model 2). Results: A total of 240 girls and 215 boys met eligibility criteria and had an outcome measure in late adolescence. Greater SSB intake throughout childhood and adolescence was associated with higher HOMA-IR, fasting glucose, and HbA1c in boys only (Figure). Also in boys, greater fruit juice intake was associated with higher HbA1c in late adolescence. Effect estimates in girls were of small magnitude and centered to the null, except for fruit juice and HbA1c with associations in the same direction as boys (Figure). We did not observe any association with respect to whole fruits for either sex. Conclusion: Findings suggest that SSBs and fruit juice consumption throughout childhood and adolescence are associated with less favorable glycemic traits in boys, suggesting greater risk of developing diabetes.

Irritability across adolescence: Examining longitudinal trajectory, stability, and associations with psychopathology and functioning at age 18

BackgroundIrritability, marked by diminished frustration tolerance, holds significant implications for youth mental health treatment. Despite prior research on irritability trajectories, understanding of individual differences during adolescence remains limited. This study examines the stability and trajectory of irritability across ages 12–18, investigating associations with psychopathology and functioning at age 18. MethodsA community sample of families with 3-year-old children (N = 518) was recruited via commercial mailing lists. Irritability was assessed at ages 12, 15, and 18 using the Affective Reactivity Index. Psychopathology at age 18 was evaluated with the Kiddie Schedule for Affective Disorders and Schizophrenia, and functioning was assessed through the UCLA Life Stress Interview. Measurement invariance analyses and latent growth curve modeling were conducted within a structural equation modeling (SEM) framework. ResultsConfigural, metric, and scalar invariance models were supported. Elevated irritability at age 12 predicted adverse outcomes at age 18, including increased psychotropic medication use, mental health treatment, suicidal ideation, self-injury, and psychiatric disorders. Importantly, these associations persisted even after accounting for corresponding variables at age 12. The trajectory of irritability during early adolescence significantly predicted heightened risks for various outcomes at age 18, including suicidal ideation, depression, anxiety, disruptive behavior disorders, and impaired interpersonal functioning. DiscussionLimitations include using only youth-reported data at age 18, limited generalizability from a mostly White, middle-class sample, and insufficient exploration of the broader developmental trajectory of irritability. Nevertheless, the findings emphasize the crucial role of irritability's trajectory in influencing various psychopathological and functional outcomes in late adolescence.

Parental unemployment and educational outcomes in late adolescence: the importance of family cohesion, parental education, and family income in a Norwegian study.

The study aimed to investigate the association between parental unemployment and grade point average and school completion in adolescence, and the importance of family cohesion, parental education, and family income in explaining these associations. Data stem from the Norwegian cross-sectional 2012 youth@hordaland-survey including 8437 adolescents (53.4% girls). Information on grade point average, school completion, parental education, and family income were retrieved from the National Education Database. Parental work status and family cohesion were assessed by adolescent self-report. Adolescents with at least one unemployed parent had lower grade point averages (3.49 compared with 3.92, P<0.001) and rates of school completion (71.9% compared with 86.6%, P<0.001) compared with adolescents with two working parents. The associations between parental unemployment and both grade point average (b = -0.22, 95% confidence interval -0.32, -0.12) and school completion (odds ratio 0.59, 95% confidence interval 0.46, 0.76) partly attenuated but remained significant when taking family cohesion, parental education, and family income into account. There was a significant interaction between parental unemployment and family cohesion on grade point average, in which the positive association between family cohesion and grade point average was weaker for adolescents with unemployed parents. Adolescents with parents outside of the workforce are at higher risk of poorer educational outcomes than peers with working parents. Combined with the positive associations between parental education, family cohesion, family income, and educational outcomes, this underscores the importance of parents for adolescent educational outcomes, and suggests that parents and the family situation should be considered when providing academic support for adolescents who struggle in upper secondary school.

Are Physical Activity Levels in Childhood Associated with Future Mental Health Outcomes? Longitudinal Analysis Using Millennium Cohort Study Data

The rising prevalence of mental health conditions among children and young adults accelerated by the COVID-19 pandemic emphasises the urgent need to address this issue effectively. A potential avenue for early diagnosis lies in physical activity patterns as individuals with mental health conditions often move less than the general population. This paper utilises Millennium Cohort Study data to investigate the relationship between childhood physical movement patterns, and mental distress and wellbeing outcomes in late adolescence. By controlling for a range of factors of both cohort members and their parents, the study employs well-adjusted logistic and linear regressions to assess the hypothesis. Objective physical movement data is collected with accelerometers, while mental distress is measured using the Kessler K6 scale and mental wellbeing using the Warwick–Edinburgh Mental Wellbeing Scale. The findings of the study suggest no significant association between raw physical movement and mental distress; however, there is suggestive evidence of a weak positive association with mental wellbeing. In addition, the study found that lower exercise levels at age 7 were associated with an increased likelihood of mental distress at age 17, highlighting the potential impact of exercise habits on mental health in adolescence. Overall, these findings suggest that raw physical activity data may be a better predictor of specific mental health outcomes, such as those assessed by the Strengths and Difficulties Questionnaire in similar studies. The paper offers recommendations for future research – such as using self-reported questionnaires to contextualise quantitative physical movement data – and a more comprehensive analysis of the cognitive and mental implications.

Comparison of Antenatal Care Visits and Pregnancy Risks on the Incidence of Stunting in Toddlers in Linge District, Central Aceh Regency, Indonesia

The problem of stunting is one of the nutritional problems faced in the world, especially in poor and developing countries. Worldwide, it is estimated that there are 178 million children under the age of five, or one in four children under five, experience stunted growth. Children who were stunted before the age of 2 had worse emotional and behavioral outcomes in late adolescence. Therefore, stunting results in poor quality of human resources, which will further affect the development of the nation's potential. This study aimed to identify a comparison of antenatal care and pregnancy risk for stunting in toddlers in Linge District, Central Aceh Regency. This study is a quantitative research using comparative studies. Comparative research is research that compares two or more symptoms. In this study, researchers compared antenatal care and pregnancy risk factors for stunting in toddlers in Linge District, Central Aceh Regency. The research subjects amounted to 60 respondents. This study shows that there are significant differences in ANC between mothers with stunted children and mothers with children who are not stunted in terms of the frequency of ANC visits and the availability of ANC services. Mothers with non-stunted children make more frequent ANC visits and receive more complete ANC services than mothers with stunted children. From the results of this study, it was also found that there was a significant difference between the education of mothers with stunted children and mothers with non-stunted children. There is a significant difference between the parity of mothers with stunted and non-stunted children. Mothers with stunted children have a higher parity than mothers with stunted children.

Sibling Bullying: A Prospective Longitudinal Study of Associations with Positive and Negative Mental Health during Adolescence

Sibling bullying is associated with poor mental health outcomes, but the relevance of specific bullying roles remains unclear. Data from a population-based study (n = 17,157, 48% female) focusing on early (11 years), middle (14 years), and late (17 years) adolescence were analyzed. Associations between sibling bullying roles in early adolescence and positive and negative mental health outcomes in late adolescence were investigated. Generally, bullying, irrespective of role, was associated with poorer mental health outcomes in late adolescence. As the frequency of bullying victimization increased between early and middle adolescence so did the severity of mental health outcomes in late adolescence. The developmental trajectories of externalizing problems were influenced by bullying in early adolescence. Sibling bullying, irrespective of role, is associated with poor mental health outcomes.

Trauma during Early Adolescence and Boys' Social Behavior: A Focus on Teen Dating Violence.

Although early adolescence is increasingly recognized as commencing a sensitive period for social development, little research exists on the impact of trauma exposure during this juncture. We hypothesized that trauma experienced during early adolescence would be particularly disruptive to the acquisition of social skills necessary for healthy future relationships. Among 1500 boys from the National Comorbidity Study Adolescent Supplement, we examined trauma exposure across developmental periods on interpersonal outcomes in late adolescence. Most (62.3%) participants reported prior exposure to at least one potentially traumatic event, and rates of such exposures generally increased linearly over time with a relative spike in exposure occurring at age 15. Trauma exposure during early adolescence, but not other developmental periods, uniquely predicted boys' perpetration of physical teen dating violence (TDV; OR = 2.2) and broader social problems (B = 2.061, SE = .091) in late adolescence. In contrast, and consistent with existing literature, trauma exposure early in development and during mid-adolescence predicted late adolescence conduct disorder diagnoses. At least in the context of early adolescent exposure, the link between trauma and TDV perpetration may be conceptualized within a broader framework of social competence rather than oft-purported antisociality. Early adolescence may present opportunities for targeted prevention of TDV and broader social problems.

Effects of childhood adversity trajectories on mental health outcomes in late adolescence: The buffering role of parenting practices in Taiwan

BackgroundChildhood adversities (CAs) have been linked with unfavorable development; however, the chronic trajectories of multiple CAs and possible heterogeneous effects are understudied. ObjectivesThis study examined the trajectories of multiple CAs and their associations with mental health outcomes in adolescence and investigated the buffering effect of parenting practices. Participants and settingWe used population-representative data from the Taiwan Education Panel Survey (2005 and 2007, n = 10,416). MethodsThis study was based on retrospectively self-reporting of six CAs, namely physical abuse, family economic hardship, parental problematic drinking, parental catastrophic health problems, parental divorce, and parental death, at three developmental periods: early childhood, middle childhood, and early adolescence. Group-based multitrajectory modeling and multiple regressions were used to identify distinct trajectories of multiple CAs and evaluate the association estimates. ResultsA total of four trajectory groups were identified: increasing family economic hardship (12.3 %), chronic physical abuse (3.3 %), chronic parental problematic drinking (2.8 %), and low adversity (81.6 %). The chronic physical abuse group had the highest levels of depressive symptoms (β = 6.61, p < .001) and suicidal ideation (Adjusted Odds Ratio [AOR] = 2.67, p < .001), whereas the chronic parental problematic drinking group had the highest level of substance abuse (AOR = 4.59, p < .001). Positive parental practices buffered the harmful effects of increasing family economic hardship in late adolescence, particularly for depressive symptoms and substance abuse. ConclusionsAdverse mental health outcomes varied among groups with distinct multiple CA trajectories. The provision of social services to train or support positive parenting practices in families experiencing economic hardship is a potentially valuable resilience strategy.

General psychopathology, internalising and externalising in children and functional outcomes in late adolescence.

BackgroundInternalising and externalising problems commonly co‐occur in childhood. Yet, few developmental models describing the structure of child psychopathology appropriately account for this comorbidity. We evaluate a model of childhood psychopathology that separates the unique and shared contribution of individual psychological symptoms into specific internalising, externalising and general psychopathology factors and assess how these general and specific factors predict long‐term outcomes concerning criminal behaviour, academic achievement and affective symptoms in three independent cohorts.MethodsData were drawn from independent birth cohorts (Avon Longitudinal Study of Parents and Children (ALSPAC), N = 11,612; Generation R, N = 7,946; Maternal Adversity, Vulnerability and Neurodevelopment (MAVAN), N = 408). Child psychopathology was assessed between 4 and 8 years using a range of diagnostic and questionnaire‐based measures, and multiple informants. First, structural equation models were used to assess the fit of hypothesised models of shared and unique components of psychopathology in all cohorts. Once the model was chosen, linear/logistic regressions were used to investigate whether these factors were associated with important outcomes such as criminal behaviour, academic achievement and well‐being from late adolescence/early adulthood.ResultsThe model that included specific factors for internalising/externalising and a general psychopathology factor capturing variance shared between symptoms regardless of their classification fits well for all of the cohorts. As hypothesised, general psychopathology factor scores were predictive of all outcomes of later functioning, while specific internalising factor scores predicted later internalising outcomes. Specific externalising factor scores, capturing variance not shared by any other psychological symptoms, were not predictive of later outcomes.ConclusionsEarly symptoms of psychopathology carry information that is syndrome‐specific as well as indicative of general vulnerability and the informant reporting on the child. The ‘general psychopathology factor' might be more relevant for long‐term outcomes than specific symptoms. These findings emphasise the importance of considering the co‐occurrence of common internalising and externalising problems in childhood when considering long‐term impact.

Temperament, Bullying, and Dating Aggression: Longitudinal Associations for Adolescents in a Romantic Relationship.

Adolescent bullying perpetration has previously been associated with dating benefits and costs in the short- and long-term, yet it is unclear how early temperament traits facilitate these associations. Therefore, the developmental pathways from temperament in early adolescence to bullying perpetration in middle adolescence and to dating outcomes in late adolescence were examined. Participants included 463 individuals who completed self-report measures on temperament traits at age 12, bullying perpetration at age 14, dating outcomes at age 19, and were in a romantic relationship at age 19. Findings from a path analysis revealed that an early adolescent temperament trait reflecting difficulty with self-regulation (i.e., lower inhibitory control) was associated with middle adolescent bullying perpetration and bullying perpetration was associated with late adolescent dating benefits (i.e., more dating partners) and costs (i.e., higher dating aggression perpetration). Lower inhibitory control also had significant indirect associations to the late adolescent dating outcomes through middle adolescent bullying perpetration. Findings suggest that although a temperament trait can facilitate adaptive dating outcomes through bullying, it can also come at a cost for romantic relationships. Results highlight the importance of early tailoring of bullying interventions to the self-regulatory difficulties of youth to prevent adverse long-term outcomes and to also recognize the challenges of developing interventions for behavior that can result in benefits.

Outcomes of ADHD Symptoms in Late Adolescence: Are Developmental Subtypes Important?

Objective: Substantial individual variation exists in the age of onset and course of ADHD symptoms over development. We evaluated whether, within this variation, meaningful developmental subtypes can be defined. Method: Using growth mixture modeling in a community-based sample (N = 1,571), we analyzed ADHD symptom trajectories based on measures taken at ages 7, 8, 9, 10, 11, 13, and 15 years. We evaluated whether those showing developmental trajectories characterized by later onsets versus early onsets differed in terms of mental health and behavioral outcomes in late adolescence (age 17 years). Result: The late onset category was best conceptualized as a milder subtype than early onset. The former was, however, more similar in outcomes to the latter than to the unaffected category, suggesting that later onsets are still associated with impairment. Conclusion: Considering diagnoses for those affected by ADHD symptoms but who do not meet current age of onset criteria may be important for ensuring that they receive appropriate support.

Association of Reported Concern About Increasing Societal Discrimination With Adverse Behavioral Health Outcomes in Late Adolescence

Public expressions of discrimination may generate stress and behavioral health problems, particularly in racial/ethnic minority or socioeconomically disadvantaged youths. To determine whether concern about increasing discrimination in society reported among adolescents during 2016 and the magnitude of increase in concern from 2016 to 2017 were associated with behavioral health outcomes by 2017 and to examine racial/ethnic or socioeconomic differences in associations. This prospective cohort survey collected data at baseline from January 2 through September 28, 2016 (11th grade), and at follow-up from January 1 through August 10, 2017 (12th grade), at 10 high schools in Los Angeles, California, recruited through convenience sampling. A total of 2572 students completed both surveys. Reported concern, worry, or stress regarding "increasing hostility and discrimination of people because of their race, ethnicity, sexual orientation/identity, immigrant status, religion, or disability status in society" were scored as "not at all" (0) to "extremely" (4). Mean ratings were calculated in a 3-item composite (range, 0-4). Self-reported days of cigarette, alcohol, or marijuana use in the past month (range, 0-30 days), number of substances used in the past 6 months (range, 0-27), mild to moderate depression (yes or no), and attention-deficit/hyperactivity disorder (ADHD) (yes or no) at follow-up. The sample of 2572 students (54.4% female; mean [SD] baseline age, 17.1 [0.4] years; 1969 [87.7%] had at least 1 parent with high school diploma) included 2530 with race/ethnicity data (1198 [47.4%] Hispanic; 482 [19.0%] Asian; 104 [4.1%] African American; 155 [6.1%] multiracial; 419 [16.6%] white; 172 [6.8%] other). Appreciable numbers of students reported feeling very or extremely concerned (baseline, 1047 [41.5%]; follow-up, 1028 [44.6%]), worried (baseline, 743 [29.7%]; follow-up, 795 [34.7%]), or stressed (baseline, 345 [13.9%]; follow-up, 353 [15.5%]) about increasing societal discrimination. Each 1-SD increase on the societal discrimination concern composite in 2016 was associated with more days of past-month cigarette (incidence rate ratio [IRR], 1.77; 95% CI, 1.42-2.20; P < .001), marijuana (IRR, 1.13; 95% CI, 1.01-1.26; P = .03), and alcohol (IRR, 1.11; 95% CI, 1.02-1.21; P = .01) use, more substances used (IRR, 1.07; 95% CI, 1.01-1.17; P = .04), and greater odds of depression (odds ratio [OR], 1.11; 95% CI, 1.01-1.23; P = .04) and ADHD (OR, 1.12; 95% CI, 1.01-1.26; P = .04) symptoms in 2017. The magnitude of increase in societal discrimination concern from 2016 to 2017 was also associated with several behavioral health problems in 2017; some associations were amplified among teenagers who were African American (IRR for cigarette smoking, 2.97; 95% CI, 1.45-6.09) or Hispanic (IRR for cigarette smoking, 1.30; 95% CI, 1.09-1.54) or had parents with less educational attainment (IRR for alcohol use, 1.41 [95% CI, 1.14-1.74]; OR for ADHD, 1.81 [95% CI, 1.13-2.89]). Concern over societal discrimination was common among youths in Los Angeles in 2016 and was associated with behavioral health problems 1 year later. Adolescents' behavioral responses to recent societal expressions of discrimination may warrant public health attention.

Oppositional defiant disorder dimensions: genetic influences and risk for later psychopathology.

This study was undertaken to determine how well two oppositional defiant disorder (ODD) dimensions (irritable and headstrong/hurtful) assessed in childhood predict late adolescent psychopathology and the degree towhich these outcomes can be attributed to genetic influences shared with ODD dimensions. Psychopathology was assessed via diagnostic interviews of 1,225 twin pairs at ages 11 and 17. Consistent with hypotheses, the irritable dimension uniquely predicted overall internalizing problems, whereas the headstrong/hurtful dimension uniquely predicted substance use disorder symptoms. Both dimensions were predictive of antisocial behavior and overall externalizing problems. The expected relationships between the irritable dimension and specific internalizing disorders were not found. Twin modeling showed that the irritable and headstrong/hurtful dimensions were related to late adolescent psychopathology symptoms through common genetic influences. Symptoms of ODD in childhood pose a significant risk for various mental health outcomes in late adolescence. Further, common genetic influences underlie the covariance between irritable symptoms in childhood and overall internalizing problems in late adolescence, whereas headstrong/hurtful symptoms share genetic influences with substance use disorder symptoms. Antisocial behavior and overall externalizing share common genetic influences with both the irritable and headstrong/hurtful dimensions.

Brain connectivity networks and longitudinal trajectories of depression symptoms in adolescence

High levels of depression during adolescence may contribute to the risk for future depression later in life. This study examined the relationship between the developmental timing of depressive symptoms, and brain structural outcomes in late adolescence. In a prior work, we examined longitudinal trajectories of depressive symptoms in 243 adolescents (121 males and 122 females), and identified four subgroups: a normative group with stable low levels of depression, two groups with declining symptoms, and one group with increasing symptoms. For the current paper, diffusion-weighted MRI images were acquired at the final wave of the study, and used to perform white matter tractography and brain network analysis. The four depression trajectory groups were tested for differences in brain connectivity variables. This revealed differences in several frontal and temporal regions. The groups that had experienced elevated depression symptoms in early adolescence differed from the normative group in a greater number of areas than the group who had experienced depression later. Affected tracts corresponded to areas of white matter that are still maturing during this period, particularly frontolimbic regions. These findings support the proposition that the timing and duration of depression symptoms during adolescence are associated with brain structural outcomes.

The Effects of Childhood and Adolescent Adversity on Substance Use Disorders and Poor Health in Early Adulthood.

Childhood and adolescent adversity have been shown to predict later mental and physical health outcomes. Understanding which aspects and developmental timings of adversity are important, and the mechanisms by which they have their impact may help guide intervention approaches. A large subset of adolescents (N = 457; Female 68.9 %) from the 10-year longitudinal Youth Emotion Project was examined to better understand the associations among childhood/adolescent adversity, substance use disorder, and later health quality. Adolescent (but not childhood) adversities were associated with poorer health in late adolescence/early adulthood, adolescent adversities were associated with subsequent onset of substance use disorder, and adolescent adversities continued to be associated with poorer health in late adolescence/early adulthood after accounting for the variance explained by substance use disorder onset. These associations were observed after statistically accounting for emotional disorders and socioeconomic status. Specific domains of adversity uniquely predicted substance use disorder and poorer health outcomes. In contrast with current recent research, our findings suggest the association between childhood/adolescent adversity and poorer health outcomes in late adolescence and emerging adulthood are not entirely accounted for by substance use disorder, suggesting efforts to curtail family-based adolescent adversity may have downstream health benefits.

The role of parents and peers on adolescents’ prosocial behavior and substance use

The focus of this study was to understand both parental and peer influence on adolescents’ prosocial and substance use outcomes. Data were drawn from the Flourishing Families Project, which consisted of 500 individuals ( Mage at Time 1 = 11.83; 51.6% female; 33% were from single-parent families) who participated at six time points, each approximately 1 year apart. Results suggest that parental warmth (at Time 2) was associated with self-regulation (Time 3), which was then associated with prosocial and deviant peer association (Time 4). Peer association was in turn related to prosocial behaviors and substance use (Time 7). Discussion focused on the role that both parents and peers play on adolescent outcomes and suggests that while peer influence during mid-adolescence is significantly linked with behavioral outcomes in late adolescence, early adolescent experiences of parental warmth also have indirect effects on the outcomes.

Neuropsychological Functioning and Attachment Representations in Early School Age as Predictors of ADHD Symptoms in Late Adolescence.

This study aimed to examine relations between parent and child attachment representations and neuropsychological functions at age 8, as well as relations between these constructs and ADHD symptoms over a 10-year period. A community-based sample of 105 children (52 boys) participated. Measures of attachment representations and a range of neuropsychological functions were collected at age 8. Parents rated emotion dysregulation and ADHD symptoms at age 8 and ADHD symptoms again at age 18. Significant, although modest, relations were found between disorganized attachment and some aspects of neuropsychological functioning in childhood. When studying outcomes in late adolescence and controlling for early ADHD symptom levels, spatial working memory and disorganized attachment remained significant in relation to both ADHD symptom domains, and one measure of inhibition remained significant for hyperactivity/impulsivity. When examining independent effects, spatial working memory and disorganized attachment were related to inattention, whereas spatial working memory and dysregulation of happiness/exuberance were related to hyperactivity/impulsivity. Our findings showing that disorganized attachment is longitudinally related to ADHD symptoms over and above the influence of both neuropsychological functioning and early ADHD symptom levels highlights the importance of including measures of attachment representations when trying to understand the development of ADHD symptoms. If replicated in more "at-risk" samples, these findings could also suggest that parent-child attachment should be taken into consideration when children are referred for assessment and treatment of ADHD.

A 6-year follow-up of a large European cohort of children with attention-deficit/hyperactivity disorder-combined subtype: outcomes in late adolescence and young adulthood.

There are very few studies on the long-term outcome of children and adolescents with ADHD-combined type in Europe. The objective of the present study is to assess the 6-year outcome (including pharmacological treatment) of a large cohort of participants with ADHD-combined type (N = 347, mean age 11.4 years) in late adolescence and early adulthood. At study entry and follow-up (mean age 17.4 years), participants were comprehensively assessed on ADHD and comorbid disorders by structured psychiatric interviews and multi-informant questionnaires. Overall functioning was assessed by the Children’s Global Assessment Scale. The retention rate was 75.6 %. The majority of participants (86.5 %) persisted in a DSM-5 ADHD diagnosis, 8.4 % had a subthreshold diagnosis, and 5.1 % remitted from the disorder at follow-up. Comorbidities decreased strongly; oppositional defiant disorder: 58 > 31 %, conduct disorder: 19 > 7 %. At follow-up, mood- and anxiety disorders were virtually non-existent following strict criteria (1–3 %). Percentage of children having had pharmacological treatment at any time increased from 79 to 91 %. On the Children’s Global Assessment Scale, 48.5 % of participants were still functionally impaired at follow-up. Parental ADHD, higher ADHD symptom severity at baseline and higher parent-reported impairment at baseline positively predicted current ADHD symptom severity (R2 = 20.9 %). Younger baseline age, higher ADHD symptom severity at baseline and higher parent-reported impairment at baseline were positively associated with poorer overall functioning (R2 = 17.8 %). Pharmacological treatment had no (beneficial) impact on either ADHD symptom severity or overall functioning. Results confirm that ADHD is largely persistent into late adolescence with severity and family history for the disorder as important risk factors.Electronic supplementary materialThe online version of this article (doi:10.1007/s00787-016-0820-y) contains supplementary material, which is available to authorized users.

Behavioral Correlates of Prioritizing Popularity in Adolescence.

Little is known about individual differences in adolescents' motivation to achieve and maintain popularity. This study examined the moderating effects of prioritizing popularity on the associations between popularity and adjustment outcomes in late adolescence. Participants were 314 Dutch eleventh-grade students (M age=16.83years; 52% male) who completed measures of popularity, prioritizing popularity, and prosocial, antisocial, and risk behaviors. It was hypothesized that associations between popularity and adjustment outcomes are stronger for adolescents who prioritize popularity. The results indicate that the combination of being popular and valuing popularity was strongly related to antisocial and risk behaviors, but not to prosocial behaviors. Adolescents' social status motivations thus play an important role in the association of popularity with antisocial and risk behaviors in late adolescence.
