Developmental relations between ADHD symptoms and bullying perpetration and victimization in adolescence

It has previously been hypothesized that individuals with elevated attention deficit hyperactivity disorder (ADHD) symptoms are at greater risk of bullying perpetration and victimization. Using autoregressive latent trajectory models with structured residuals (ALT‐SR) and four waves (ages 11, 13, 15, and 17) of longitudinal data from the normative z‐proso study (n = 1526, 52% male), we evaluated the developmental relations between ADHD and bullying using both self‐ and teacher‐reported ADHD symptom data. Analyses suggested that ADHD symptoms primarily increase the risk of bullying perpetration, with a within‐person effect of ADHD symptoms on bullying perpetration symptoms identified across ages 13–15 (β = .13) and ages 15–17 (β = .19) based on self‐reported ADHD symptoms and a similar effect identified across ages 11–13 (β = .24) and 13–15 (β = .29) based on teacher‐reported inattention symptoms. There were also some indications of reciprocal effects and effects involving victimization that merit further exploration in future research. Results imply that the content of bullying intervention and prevention programs should take account of ADHD symptoms to ensure that those with elevated symptoms can benefit as much as their typically developing peers. This will involve addressing bullying perpetration that may reflect impulsive/reactive aggression and impaired social skills rather than instrumental aggression. Further, programs should go beyond classical curriculum/classroom‐based delivery to ensure that individuals with elevated ADHD symptoms can be successfully engaged.     

Body mass index,peer victimization,and body dissatisfaction across 7 years of childhood and adolescence: Evidence of moderated and mediated pathways

Numerous studies have reported that children and adolescents who are overweight are more likely to get bullied, yet the literature is replete with methodological limitations. We examined the transactional associations between peer victimization and body mass index (BMI), considering potential mediating (body dissatisfaction) and moderating (biological sex) factors. Participants (n = 631) came from the McMaster Teen Study, where students were assessed annually between Grades 5–11, approximately half were girls (53.9%), and the majority were white (76.4%). Peer victimization (from Grade 5) and body dissatisfaction (from Grade 6) were self‐reported by students, while parents reported their child's height and weight (from Grade 5). Cascade models were built up sequentially using path analysis across 2‐year increments (Grades 5, 7, 9, and 11). The final model had excellent fit to the data (χ² = 73.961, df = 66, p = 0.234). Grade 5 peer victimization had a direct effect on BMI across a 2‐year period in girls (b = 0.59, SE = 0.21, p = 0.005) and boys (b = 0.82, SE = 0.30, p = 0.006), and an indirect effect on BMI via body dissatisfaction across a 4‐year period (b = 0.074, 95% CI = 0.012–0.152, p = 0.036). At no point did BMI directly increase risk for peer victimization, yet there were indirect effects via body dissatisfaction among girls but not boys. Peer victimization and body dissatisfaction were proximally and longitudinally related at every time point and there was a transactional association in late‐adolescence among girls but not boys. Targeting modifiable factors in the social (peer victimization) and psychological (body dissatisfaction) domains may limit accelerated weight gain and the health risks associated with excess adiposity.     

Prospective linkages between peer victimization and externalizing problems in children: a meta-analysis

Previous meta-analytic research has shown both concurrent and prospective linkages between peer victimization and internalizing problems in youth. However, the linkages between peer victimization and externalizing problems over time have not been systematically examined, and it is therefore unknown if externalizing problems are antecedents of victimization, consequences of victimization, both, or neither. This study provides a meta-analysis of 14 longitudinal studies examining prospective linkages between peer victimization and externalizing problems (n = 7,821). Two prospective paths were examined: the extent to which peer victimization at baseline predicts future residualized changes in externalizing problems, as well as the extent to which externalizing problems at baseline predict future residualized changes in peer victimization. Results revealed significant associations between peer victimization and subsequent residualized changes in externalizing problems, as well as significant associations between externalizing problems and subsequent residualized changes in peer victimization. Hence, externalizing problems function as both antecedents and consequences of peer victimization.     

流动儿童同伴侵害的特点及与内化问题的循环作用关系:一项追踪研究

本研究采用纵向设计,以北京市426名四、五年级流动儿童为被试,进行连续4次的追踪测查,考察流动儿童同伴侵害的特点及其与内化问题的动态相互作用关系。结果发现:(1)打工子弟学校流动儿童的同伴侵害与内化问题水平比公立学校流动儿童高;流动儿童的流动性越大,同伴侵害和内化问题越多。(2)控制了性别、年级、家庭社会经济地位(SES)和流动性后,从T1到T2,同伴侵害与孤独感为相互作用关系,且同伴侵害可以显著预测抑郁,但对社交焦虑的预测作用不显著,而从T2到T4,同伴侵害和3种内化问题的相互作用模式完全一致,即T2时的社交焦虑、抑郁和孤独感显著预测T3的同伴侵害,进而显著预测T4的社交焦虑、抑郁和孤独感。(3)抑郁、孤独感与同伴侵害的循环作用在两类流动儿童中具有较强的稳定性,而在社交焦虑和同伴侵害的模型中,打工子弟学校流动儿童的同伴侵害对社交焦虑的作用比公立学校流动儿童更大。可见,同伴侵害和内化问题呈循环作用关系,未来预防/干预研究可以聚焦于减少流动儿童的同伴侵害或内化问题的角度打破二者的恶性循环,帮助他们建立良好的人际关系,构建良性循环,促进他们的积极发展。     

Religious Involvement and Health Over Time: Predictive Effects in a National Sample of African Americans

In this study, two telephone interviews that assessed both religious involvement and health‐related quality of life were conducted approximately 2.5 years apart in a national sample of 290 African Americans. Religious involvement was assessed with an instrument that measured both personal religious beliefs (e.g., having a personal relationship with God) and more public religious behaviors (e.g., attending church services). Health‐related quality of life was measured with version 2 of the Medical Outcomes Study 12‐item short form (SF‐12v2). Structural equation models indicated that higher religious beliefs at baseline predicted better physical and mental health 2.5 years later. Higher religious behaviors at baseline contributed smaller, complementary suppression effects. Physical and mental health indicators from the SF‐12v2 at baseline did not predict changes in either religious beliefs or religious behaviors over time. These findings indicate that, for African Americans, personal religious beliefs lead to beneficial health effects over time, whereas individual differences in health do not appear to predict changes in religious involvement.     

Sex and age group differences in the associations between sleep duration and BMI from adolescence to young adulthood

Objective: We examine concurrent and longitudinal associations between sleep duration (SD) and body mass index (BMI) from adolescence to young adulthood, controlling for physical activity and internalising symptoms. Sex and age group differences (early adolescent group ages 12–15 years and late adolescent group ages 16–18 years) are examined.

Design: A randomly selected community-based sample of youth (N = 662; 48.3% males) were surveyed biannually from 2003 (T1) to 2014 (T6).

Results: We found sex and age group differences for the concurrent and longitudinal associations between SD and BMI. For males, shorter SD at baseline was concurrently related to higher BMI. For females, shorter SD at baseline was associated with longitudinal increases in BMI, for the late adolescent group only.

Conclusion: Findings show that the association between SD and BMI, previously shown in childhood, continues to be significant in adolescence and young adulthood. Developmentally appropriate and sex-specific strategies for motivating and supporting healthy sleep habits in adolescence that may help to prevent weight gain into young adulthood are discussed.     

Midline crossing: developmental trend from 3 to 10 years of age in a preferential card-reaching task

We assessed 110 left-handed and 322 right-handed children aged from 3 to 10 years, using Bishop's card-reaching task. Manual body midline crossings were observed. A regular developmental trend was observed from 3 to 10 years: older children crossed the body midline more frequently when reaching for cards than did younger children. The factor age explained 4.9% of the variance. Significant differences appeared between 3-4 years old children and 8-10 years old children. The effect of the spatial position of the cards was also significant: the contralateral hand was used less often to reach cards at the most extreme positions. These findings in this task demonstrate that the development of the degree of handedness follows a long developmental trend.     

A study of the psychometric properties of the Beck Depression Inventory‐II,the Montgomery and Åsberg Depression Rating Scale,and the Hospital Anxiety and Depression Scale in a sample from a healthy population

The objective of this study is to evaluate internal consistency and psychometric properties of the Hospital Anxiety and Depression Scale (HADS), the Beck Depression inventory‐II (BDI‐II) and the Montgomery and Åsberg Depression Rating Scale (MADRS) for screening for major depressive episode (MDE) in a selected sample from a healthy population. Participants answered the BDI‐II and the HADS questionnaires and were interviewed with MADRS. The Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders (DSM)‐IV Axis I Disorders‐Clinician Version (SCID‐CV) was used to diagnose MDE. Current MDE was diagnosed in 20 (6%) of the 357 participants. All three scales including the depression sub‐scale for HADS had high area under the receiver operating characteristics curve (ROC) (AUC) (0.84–0.87), and internal consistency was also high for all scales (0.75–0.89). Optimal cut‐off for MDE was ≥ 12 for BDI‐II, MADRS ≥ 8, HADS total ≥ 9, and HADS‐D ≥ 4, which all resulted in sensitivities = 85% and specificities > 78%. Diagnostic accuracy was low on all depression scales (Cohen's kappa = 0.20–0.40). Reports of the properties of depression scales in a healthy population are limited. We found BDI‐II, HADS and MADRS to be acceptable as screening instruments for MDE in a selected sample from healthy population with recommend cut‐offs as mentioned above.
