Cognitive Functioning,Behavior, and Quality of Life After Stroke in Childhood

Rationale: To provide a better understanding of cognitive functioning, motor outcome, behavior and quality of life after childhood stroke and to study the relationship between variables expected to influence rehabilitation and outcome (age at stroke, time elapsed since stroke, lateralization, location and size of lesion).

Methods: Children who suffered from stroke between birth and their eighteenth year of life underwent an assessment consisting of cognitive tests (WISC-III, WAIS-R, K-ABC, TAP, Rey-Figure, German Version of the CVLT) and questionnaires (Conner's Scales, KIDSCREEN).

Results: Twenty-one patients after stroke in childhood (15 males, mean 11;11 years, SD 4;3, range 6;10–21;2) participated in the study. Mean Intelligence Quotients (IQ) were situated within the normal range (mean Full Scale IQ 96.5, range IQ 79–129). However, significantly more patients showed deficits in various cognitive domains than expected from a healthy population (Performance IQ p?=?.000; Digit Span p?=?.000, Arithmetic's p?=?.007, Divided Attention p?=?.028, Alertness p?=?.002). Verbal IQ was significantly better than Performance IQ in 13 of 17 patients, independent of the hemispheric side of lesion. Symptoms of ADHD occurred more often in the patients' sample than in a healthy population (learning difficulties/inattention p?=?.000; impulsivity/hyperactivity p?=?.006; psychosomatics p?=?.006). Certain aspects of quality of life were reduced (autonomy p?=?.003; parents' relation p?=?.003; social acceptance p?=?.037). Three patients had a right-sided hemiparesis, mean values of motor functions of the other patients were slightly impaired (sequential finger movements p?=?.000, hand alternation p?=?.001, foot tapping p?=?.043). In patients without hemiparesis, there was no relation between the lateralization of lesion and motor outcome. Lesion that occurred in the midst of childhood (5–10 years) led to better cognitive outcome than lesion in the very early (0–5 years) or late childhood (10–18 years). Other variables such as presence of seizure, elapsed time since stroke and size of lesion had a small to no impact on prognosis.

Conclusion: Moderate cognitive and motor deficits, behavioral problems, and impairment in some aspects of quality of life frequently remain after stroke in childhood. Visuospatial functions are more often reduced than verbal functions, independent of the hemispheric side of lesion. This indicates a functional superiority of verbal skills compared to visuospatial skills in the process of recovery after brain injury. Compared to the cognitive outcome following stroke in adults, cognitive sequelae after childhood stroke do indicate neither the lateralization nor the location of the lesion focus. Age at stroke seems to be the only determining factor influencing cognitive outcome.     

Neuropsychological Functioning in Children with Posttraumatic Stress Disorder

Posttraumatic stress disorder (PTSD) has been associated with deficits in the areas of verbal memory and learning, executive functioning, working memory, and attention in adults. Findings have been less consistent in the few studies examining neuropsychological functioning in childhood PTSD, which are often limited by comparing children with PTSD to children without trauma histories, making it unclear whether observed neuropsychological deficits are related to trauma exposure or to PTSD symptomatology. In an ethnically diverse sample of 62 children who witnessed intimate partner violence (n = 27 PTSD+ and 35 PTSD?), children with PTSD exhibited slower and less effective learning, heightened sensitivity to interference, and impaired effect of rehearsal on memory acquisition on the California Verbal Learning Test – Children's Version, a word list learning task. Both groups performed in the below average range on measures of executive functioning, attention, and intellectual ability.     

Linkages between childhood executive functioning and adolescent social functioning and psychopathology in girls with ADHD

We followed an ethnically and socioeconomically diverse sample of preadolescent girls with ADHD (n = 140) and matched comparison girls (n = 88) over a period of 5 years, from middle childhood through early/midadolescence, with the aim of determining whether childhood levels of executive function (EF) would predict adolescent multi-informant outcomes of social functioning and psychopathology, including comorbidity between externalizing and internalizing symptomatology. Predictors were well-established measures of planning, response inhibition, and working memory, along with a control measure of fine motor control. Independent of ADHD versus comparison group status, (a) childhood planning and response inhibition predicted adolescent social functioning and (b) childhood planning predicted comorbid internalizing/externalizing disorders in adolescence. Subgroup status (ADHD-Combined, ADHD-Inattentive, and comparison) moderated the relationship between childhood planning and adolescent internalizing/externalizing comorbidity, with the combined type revealing particularly strong associations between baseline planning and adolescent comorbidity. Mediation analyses indicated that adolescent social functioning mediated the prediction from childhood EF to comorbidity at follow-up; in turn, in the girls with ADHD, adolescent comorbidity mediated the prediction from childhood EF to social functioning at follow-up. We conclude that childhood interventions should target EF impairments in addition to behavioral symptoms.     

Causal Attribution: Analysis of Patterns and Influencing Factors Among Learners at a Higher Education Institution

The study explored the academic patterns and implications of academic attributions made by students who had been given test feedback at a higher learning institution in Zimbabwe. A random sample of 8 (female = 4; male= 4; mean age = 21.9, passed a test = 4; failed the test = 4) participants was purposefully selected from a class of second year students majoring in psychology and human resources management. Audio-taped semi-structured interviews were conducted to collect data. Thematic content analysis was used to analyse data. Results indicate that culture and gender moderate academic causal attributions.     

Children with Attention Deficit Hyperactivity Disorder

ABSTRACT

It is estimated that there have been over 4,000 articles in the literature on the subject of attentional problems, addressing its etiology, epidemiology, assessment, diagnosis, and treatment. This article reviews recent and relevant literature with an eye toward functional conclusions and linkages between assessment and intervention. The article concludes by providing a problem-solving model that integrates parent or teachers' referral concerns, reasons for these concerns, assessment methods, and intervention strategies. In the end, four definitive conclusions are drawn, and the importance of multimodal strategies that collaboratively involve home, school, and community settings is emphasized.     

Social support as a mediator of religious involvement and physical and emotional functioning in a national sample of African-Americans

Researchers propose social support as one of the factors that may explain the positive relationship often observed between religious involvement and health outcomes. African-Americans are a population that tends to have higher than average levels of religious involvement and are also disproportionately impacted by most health conditions. The present study sought to determine whether social support mediates the role of religious involvement in physical and emotional functioning and depressive symptoms, among a national probability sample of African-Americans (N = 803). Study participants completed telephone interviews. We used structural equation modelling to test hypotheses based on the theoretical model. Findings suggest evidence for a mediating role of belonging and tangible support in the association between religious behaviours and physical functioning as well as depression. There was no mediational role played by appraisal support, or for emotional functioning. Implications for faith-based health promotion interventions are discussed.     

大鱼小池效应研究回顾及展望

大鱼小池效应(Big Fish Little Pond Effect)是解释不同教育情境中学生自我概念水平的一个特定概念,Marsh将其定义为：能力同等的学生,在平均成绩较高的学校或班级里的学业自我概念较低,而在平均成绩较低的学校或班级则学业自我概念会较高。大鱼小池效应包括学生采用概括他人和特定他人的比较标准所分别产生的同化效应和对比效应,社会比较对学业自我概念形成具有特定影响。大鱼小池效应的未来研究可以从研究方法的改进、调节变量的控制和跨文化比较等方面拓展。     

Factor structure of the construct of adaptive behavior in children with and without intellectual disability

Although the presence of significant limitations in adaptive behavior constitutes one of the three necessary criteria for diagnosing intellectual disability, adaptive behavior structure has always been the subject of considerable controversy among researchers. The main goal of this study is to extend previous research results that provide further support to a multidimensional structure of conceptual, social, and practical skills compared to the unidimensional structure. One-factor and 3-correlated factors models as measured by 15 observable indicators were analyzed by means of confirmatory factor analysis (CFA), as well as their relationships with one second-order factor (i.e., adaptive behavior). To that end, 388 children with and without intellectual disabilities were assessed with the Diagnostic Adaptive Behavior Scale (DABS). Results of CFA indicated that the 3 first-order factors solution provides the best fit to the data. Reliability and validity of the multidimensional model were also analyzed through different methods such as the composite reliability and the average variance extracted. Finally, implications of these findings and possible directions for future research are discussed.     

Measuring moral reasoning using moral dilemmas: evaluating reliability,validity, and differential item functioning of the behavioural defining issues test (bDIT)

ABSTRACT

We evaluated the reliability, validity, and differential item functioning (DIF) of a shorter version of the Defining Issues Test-1 (DIT-1), the behavioural DIT (bDIT), measuring the development of moral reasoning. About 353 college students (81 males, 271 females, 1 not reported; age M = 18.64 years, SD = 1.20 years) who were taking introductory psychology classes at a public University in a suburb area in the Southern United States participated in the present study. First, we examined the reliability of the bDIT using Cronbach’s α and its concurrent validity with the original DIT-1 using disattenuated correlation. Second, we compared the test duration between the two measures. Third, we tested the DIF of each question between males and females. Findings reported that first, the bDIT showed acceptable reliability and good concurrent validity. Second, the test duration could be significantly shortened by employing the bDIT. Third, DIF results indicated that the bDIT items did not favour any gender. Practical implications of the present study based on the reported findings are discussed.     

Invariance on a reading comprehension test in European Portuguese: A differential item functioning analysis between students from rural and urban areas

The aim of this study was to determine whether the items from a reading comprehension test in European Portuguese function differently across students from rural and urban areas, which biases the test validity and the equity in assessment. The sample was composed of 653 students from second, third and fourth grades. The presence of differential item functioning (DIF) was analysed using logistic regression and the Mantel–Haenszel procedure. Although 17 items were flagged with DIF, only five items showed non-negligible DIF in all effect-size measures. The evidence of invariance across students with rural or urban backgrounds for most of the items supports the validity of the test though the five identified items should be further investigated.
