Does Bullying Victimization Suppress IQ? The Effects of Bullying Victimization on IQ in Iraqi and African American Adolescents: A Traumatology Perspective

This study explored the effects of bullying victimization (BV), as a Type II traumatic stressor, on intelligence quotient (IQ), posttraumatic stress disorder (PTSD), and complex PTSD symptoms. Participants were 390 African American and Iraqi refugee adolescents. Measures of BV, cumulative life trauma, PTSD, discrimination, and IQ were administered. Correlational, multilevel regression, and path analyses were conducted. BV, independent of cumulative trauma, and discrimination were found to have significant direct effects on increased PTSD symptoms and significant direct and indirect negative effects on perceptual reasoning, processing speed, and working memory. BV was also associated with increases in the discrepancy between perceptual reasoning and verbal comprehension. The implications of these results for the prevention and treatment of bullying victims are discussed.     

Identity Distress Among Youth Exposed to Natural Disasters: Associations with Level of Exposure,Posttraumatic Stress,and Internalizing Problems

Identity distress involves intense or prolonged upset or worry about personal identity issues including long-term goals, career choice, friendships, sexual orientation and behavior, religion, values and beliefs, and group loyalties. Research suggests that trauma exposure and subsequent posttraumatic stress disorder (PTSD) symptoms may negatively affect identity development and psychological adjustment. However, little is known about their specific associations with identity distress and internalizing problems among disaster-exposed adolescents. This study aimed to examine these associations in a sample of 325 adolescents (60% female; 89% African American) who experienced a major natural disaster and its aftermath. The results indicated that identity distress was positively associated with age, hurricane exposure, PTSD symptoms, and internalizing problems. Linear regression analyses also showed that identity distress was uniquely associated with internalizing symptoms and that there was an indirect effect of hurricane exposure on identity distress via PTSD symptoms. PTSD symptoms moderated the link between identity distress and internalizing symptoms, with a significant positive slope found for youth with more PTSD symptoms. Findings were generally consistent with previous work and predictions, and they add to the extant knowledge about identity distress by providing data on the linkages among disaster exposure, posttraumatic stress, and internalizing problems in adolescents.     

青少年依恋对创伤后应激障碍和创伤后成长的影响:认知重评和表达抑制的中介作用

本研究采用创伤暴露程度问卷、父母与同伴依恋问卷、情绪调节策略问卷、DSM-5的PTSD症状核查表、创伤后成长问卷,以汶川地震8.5年后极重灾区的1153名青少年为被试,考察青少年的依恋、认知重评、表达抑制、PTSD和PTG之间的关系。结果发现：青少年的依恋可以直接负向预测PTSD、直接正向预测PTG;青少年的依恋可以通过认知重评负向预测PTSD、正向预测PTG,也可以通过表达抑制负向预测PTSD,却不能通过表达抑制预测PTG。     

Stability of young children's attachment representations: Influence of children's and caregiver's characteristics

This research explores the stability of attachment representations, assessed by the Attachment Story Completion Task, within early childhood. Hypotheses were also formed about the influence of parenting, externalizing behavior and intelligence quotient (IQ) on the developmental course of children's attachment representations. Data were collected from 358 French-speaking Belgian children. Security and disorganization showed a linear improvement with age. The effect of time on the two growth curves was influenced by the child's externalizing behavior. When language abilities were controlled for in a subsample of referred children for externalizing behavior, the growth in security was found to be influenced by reasoning IQ, but the effects for disorganization were unchanged. The implications of the results for both research and clinical purposes are discussed.     

Perceived family conflict, parental attachment, and depression in African American female adolescents

The purpose of this study was to test a hypothesized model that explored the degree to which parental attachment mediated the relationship between perceived family conflict and depression in a sample of 283 African American female adolescents. Results revealed that perceived family conflict had both a direct and an indirect effect on depression, with parental attachment mediating 28% of the effect of perceived family conflict on depression. Implications of the findings are discussed.     

An evaluation of differential prediction of WIAT achievement scores from WISC-III FSIQ across ethnic and gender groups

This study examines differential prediction of WIAT achievement scores based on WISC-III FSIQ in white as compared with African American and Hispanic children, and in females as compared with males. A procedure which allows simultaneous comparisons of slopes and intercepts across groups is employed. The results are consistent with previous research findings in supporting the general absence of bias in predicting achievement from IQ.     

Religiousness and Depressive Symptoms in Five Ethnic Adolescent Groups

This study examined the relation between religiousness and depressive symptoms in African American, Asian American, European American, Hispanic American, and Native American adolescents (N = 13,317) in the United States with self-esteem and school attachment as potential mediators in this link. The data were taken from a nationally represented sample of adolescents in Grades 7 through 12, from the National Longitudinal Study of Adolescent Health (Add Health). Structural equation analyses with measurement and structural invariance across the five ethnic groups and gender supported the model that religiousness, as a composite of internal and external religiousness items, negatively predicted depressive symptoms 1 year later controlling for baseline depressive symptoms. Self-esteem and school attachment partially mediated this link but only for European American and African American adolescents.     

Verbal–spatial IQ discrepancies impact brain activation associated with the resolution of cognitive conflict in children and adolescents

Verbal–spatial discrepancies are common in healthy individuals and in those with neurodevelopmental disorders associated with cognitive control deficits including: Autism Spectrum Disorder, Non‐Verbal Learning Disability, Fragile X, 22q11 deletion, and Turner Syndrome. Previous data from healthy individuals suggest that the magnitude of the difference between verbal IQ (VIQ) and performance IQ (PIQ) scores (the VIQ>PIQ discrepancy) is associated with reduced thickness in frontal and parietal cortices (inferior frontal, anterior cingulate, inferior parietal lobule, and supramarginal gyrus) that support cognitive control. Unknown is whether the VIQ>PIQ discrepancy is associated with functional deficits in these areas in healthy or ill children and adolescents. We assessed the effects of the VIQ>PIQ discrepancy on fMRI BOLD response during the resolution of cognitive conflict in 55 healthy children and adolescents during performance of a Simon Spatial Incompatibility task. As the magnitude of the VIQ>PIQ discrepancy increased, activation of fronto‐striatal, limbic, and temporal regions decreased during conflict resolution (p < .05, corrected). In exploratory analyses, the VIQ>PIQ discrepancy was associated with reduced functional connectivity from right inferior frontal gyrus to right thalamus and increased functional connectivity to right supramarginal gyrus (ps < .03, uncorrected). The VIQ>PIQ discrepancy may be an important aspect of an individual's cognitive profile and likely contributes to, or is associated with, deficient cognitive control processes characteristic of many childhood disorders.     

Gender and ethnic differences in body image and opposite sex figure preferences of rural adolescents

This study examined whether rural adolescents would report gender and ethnic differences in body image similar to those that have been observed in urban samples. Data were analyzed for 384 rural adolescents (57% African American, 43% Caucasian, mean age 13 years) to determine gender and ethnic differences in body dissatisfaction, body size discrepancy, and current and ideal figure ratings. Females wanted to be smaller and reported more body dissatisfaction than did males. Caucasian females reported the most body dissatisfaction. African Americans reported larger current and ideal figure ratings than did Caucasians. African Americans preferred larger opposite sex figures than did Caucasians. Both African American and Caucasian males selected a larger female figure as ideal than was selected by females. Results demonstrated that gender and ethnic differences exist in body image for rural adolescents. This frequently overlooked population may benefit from further study. Implications of findings and limitations of the study are also discussed.     

The Impact of Race on Metabolic Disease Risk Factors in Women With and Without Posttraumatic Stress Disorder

The literature on PTSD and metabolic disease risk factors has been limited by lacking investigation of the potential influence of commonly comorbid disorders and the role of race. In this study data were provided by a sample of 134 women (63 PTSD and 71 without PTSD). Separate sets of models examining associations of psychiatric disorder classifications with metabolic disease risk factors were used. Each model included race (African American or Caucasian), psychiatric disorder, and their interaction. There was an interaction of race and PTSD on body mass index, abdominal obesity, and triglycerides. While PTSD was not generally associated with deleterious health effects in African American participants, PTSD was related to worse metabolic disease risk factors in Caucasians. MDD was associated with metabolic disease risk factors, but there were no interactions with race. Results support the importance of race in the relationship between PTSD and metabolic disease risk factors. Future research would benefit from analysis of cultural factors to explain how race might influence metabolic disease risk factors in PTSD.     

Family Therapy with Unmarried African American Mothers and Their Adolescents

Almost two-thirds of African American births are to unmarried mothers, and these single parents are among the most economically vulnerable in the United States. The effects of chronic stressors such as poverty can compromise the ability of these mothers to parent effectively, particularly during the developmental period of adolescence, typically a stressful phase of parenting. This article describes a multidimensional family therapy (MDFT) approach to working with African American adolescents who have drug and/or behavior problems. It is maintained that addressing the intrapersonal functioning of African American single mothers is vital if they are to re-establish the attachment bonds necessary for the maintenance of essential parental influence in the lives of their adolescents. Through systematic attention to the parent as an individual, leading to a balance between self-care and care for others, parental supervision is more easily achieved and relational impasses between parent and adolescent more equitably resolved.     

Cultural Differences in the Reciprocal Relations between Emotion Suppression Coping,Depressive Symptoms and Interpersonal Functioning among Adolescents

The current study examined the prospective relations between emotion suppression and maladjustment (i.e., depressive symptoms, family stress events, peer stress events, and family and peer support) among Vietnamese American (n = 372) and European American adolescents (n = 304). We found that at baseline Vietnamese Americans adolescents reported greater use of emotion suppression coping than European American adolescents. Multi-group structural equation modeling indicated that for European American teens emotion suppression was significantly related to increased depression symptoms and decreased quality of peer relationships. In contrast, for the Vietnamese Americans teens emotion suppression relations to later maladjustment was either nonsignificant or attenuated relative to the European American. These findings suggest ethnic group differences in both the utilization, and consequences and function of emotion suppression among Vietnamese American and European American adolescents.     

Cognitive and attentional functioning in adolescents and young adults with Tetralogy of Fallot and d-transposition of the great arteries

The objective of this study is to investigate cognitive and attentional function in adolescents and young adults with operated congenital heart disease. Previous research has indicated that children with congenital heart disease have deficits in broad areas of cognitive function. However, less attention has been given to survivors as they grow into adolescence and early adulthood. The participants were 18 non-syndromic adolescents and young adults with tetralogy of Fallot and d-transposition of the great arteries that required cardiac surgery before the age of 5 years, and 18 healthy, unaffected siblings (11–22 years of age for both groups). Cases with congenital heart disease and their siblings were administered Wechsler Intelligence scales and reported attention problems using the Achenbach System of Empirically Based Assessments. Cases were compared to both healthy siblings and established norms. Cases performed significantly lower than siblings on full scale IQ and processing speed, and significantly lower than norms on perceptual reasoning. Cases also reported more attention problems compared to both siblings and norms. Effect sizes varied with medium-to-large effects for processing speed, perceptual reasoning, working memory, and attention problems. Findings suggest that neurocognitive function may continue to be affected for congenital heart disease survivors in adolescence and young adulthood, and that comparisons to established norms may underestimate neurocognitive vulnerabilities.     

PTSD SYMPTOMS AND SELF-RATED RECOVERY AMONG ADULT SEXUAL ASSAULT SURVIVORS: THE EFFECTS OF TRAUMATIC LIFE EVENTS AND PSYCHOSOCIAL VARIABLES

Prior research has demonstrated that self-blame is predictive of more posttraumatic stress disorder (PTSD) symptoms and poorer recovery ( Frazier, 2003 ; Koss, Figueredo, & Prince, 2002 ), and perceived control over recovery is associated with less distress ( Frazier, 2003 ) in adult sexual assault (ASA) survivors. A structural equation model was tested to examine the role of traumatic events, self-blame, perceived control over recovery, and coping strategies on PTSD symptoms and self-rated recovery in women ASA survivors. Adaptive coping partially mediated the effects of other traumas, self-blame, and perceived control over recovery on PTSD symptoms and showed a small positive association with increased PTSD symptoms. As hypothesized, maladaptive coping partially mediated the effects of other traumas, self-blame, and perceived control over recovery on both PTSD symptoms and self-rated recovery; greater maladaptive coping was associated with increased PTSD symptoms and lower self-rated recovery. Implications and directions for future research are discussed.     

Do African American Male and Female Adolescents Differ in Technological Engagement?: The Effects of Parental Encouragement and Adolescent Technological Confidence

African Americans, especially African American women, remain one of the most underrepresented groups in technology-based degrees and careers. However, little is known about whether gender differences permeate African American adolescents’ engagement in technology in earlier development, such as in middle and high school (ages 12–18). Drawing on an ecological and intersectional framework, we examined if African American male and female adolescents differed in technological engagement and what contextual factors affected their engagement. We hypothesized that parental encouragement would be associated with greater technological confidence in adolescents, which would be linked to more experiences with and interests in technology. Further, we investigated if these associations would vary by adolescents’ and parents’ gender. Survey data from 1041 African American parent-adolescent dyads highlighted that adolescents had less experience and interest with technical activities than with creative activities, especially among female adolescents. More parents encouraged adolescent sons but limited daughters to use technology, yet female adolescents reported greater technological confidence. Moderated mediation analyses revealed that adolescents’ technological confidence mediated the positive association between parental encouragement and adolescents’ technological engagement across all parent-adolescent dyads, but with some nuances. Our findings suggest that prospective gender studies and educational programs should consider the influences of parenting and gender on promoting African American adolescents’ technological involvement and confidence.

     

Peer status in an ethnic context: Associations with African American adolescents' ethnic identity

This investigation examined the association between ethnic identity centrality and peer status for African American adolescents who represented a sizable proportion, yet numerical minority within a high school context. Initial analyses indicated that a traditional sociometric nomination procedure did not adequately characterize peer status for African American adolescents. A modified nomination procedure varying the ethnicity of nominators yielded measures of African American adolescents' peer acceptance/rejection and perceived popularity as rated by African American or European American peers. Results suggest that high levels of peer acceptance and popularity as rated by African American peers were associated with high ethnic identity centrality; however, acceptance and popularity as rated by European American peers were unrelated to ethnic identity centrality among African American adolescents. Findings suggest the importance of examining peer status of African American adolescents with consideration given to ethnicity as a relevant context.     

创伤暴露程度对青少年物质滥用的影响：创伤后应激障碍与依恋的中介作用

为了考察汶川地震后青少年的创伤暴露程度、创伤后应激障碍（PTSD）、父母依恋和同伴依恋与物质滥用之间的关系,采用创伤暴露程度问卷、儿童创伤后应激障碍症状量表、父母与同伴依恋问卷和物质滥用问卷对汶川县和茂县的1435名中学生进行调查,选取有物质滥用的青少年354名作为本研究的对象。结果发现：创伤暴露程度可以直接正向预测作用物质滥用。不过,在创伤暴露与物质滥用直接关系之间加入PTSD、父母和同伴依恋之后,创伤暴露程度对物质滥用的直接预测作用不再显著,并且创伤暴露程度不能通过同伴依恋预测物质滥用,也不能通过PTSD经同伴依恋对物质滥用发挥多重中介作用;但创伤暴露程度能通过PTSD正向预测物质滥用,可以通过父母依恋负向预测物质滥用,并且创伤暴露程度还可以通过PTSD经过父母依恋对物质滥用发挥正向的多重中介作用。     

Non-verbal IQ is correlated with visual field advantages for short duration coherent motion detection in deaf signers with varied ASL exposure and etiologies of deafness

Studies have reported a right visual field (RVF) advantage for coherent motion detection by deaf and hearing signers but not non-signers. Yet two studies [Bosworth R. G., & Dobkins, K. R. (2002). Visual field asymmetries for motion processing in deaf and hearing signers. Brain and Cognition, 49, 170-181; Samar, V. J., & Parasnis, I. (2005). Dorsal stream deficits suggest hidden dyslexia among deaf poor readers: Correlated evidence from reduced perceptual speed and elevated coherent motion detection thresholds. Brain and Cognition, 58, 300-311.] reported a small, non-significant RVF advantage for deaf signers when short duration motion stimuli were used (200-250 ms). Samar and Parasnis (2005) reported that this small RVF advantage became significant when non-verbal IQ was statistically controlled. This paper presents extended analyses of the correlation between non-verbal IQ and visual field asymmetries in the data set of Samar and Parasnis (2005). We speculate that this correlation might plausibly be driven by individual differences either in age of acquisition of American Sign Language (ASL) or in the degree of neurodevelopmental insult associated with various etiologies of deafness. Limited additional analyses are presented that indicate a need for further research on the cause of this apparent IQ-laterality relationship. Some potential implications of this relationship for lateralization studies of deaf signers are discussed. Controlling non-verbal IQ may improve the reliability of short duration coherent motion tasks to detect adaptive dorsal stream lateralization due to exposure to ASL in deaf research participants.
