The relationship between compulsive behaviour and academic achievement across the three genetic subtypes of Prader–Willi syndrome

Background Prader–Willi syndrome (PWS) is a genetic syndrome associated with several physical, cognitive and behavioural characteristics. For many individuals with this syndrome, compulsive behaviour is often noted in both food and non‐food situations. The focus of this paper is on the non‐food‐related compulsions in individuals with PWS and comparing differences across the three genetic subtypes of the syndrome. Methods Compulsive behaviours in 73 people with PWS were assessed using the Yale‐Brown Obsessive Compulsive Scale and the Compulsive Behavior Checklist. Compulsive behaviour and its relation to IQ and academic achievement also were evaluated. Phenotypic differences were characterized for the three most common genetic subtypes of the disorder: 16 individuals with the long Type I (TI) 15q deletion, 26 individuals with the short Type II (TII) 15q deletion and 31 individuals with maternal disomy 15. Results There appeared to be important differences between the two deletion subtypes. Specifically, individuals with the TI deletion had more compulsions regarding personal cleanliness (i.e. excessive bathing/grooming), and their compulsions were more difficult to interrupt and interfered with social activities more than the other subtypes. Individuals with the TII deletion were more likely to have compulsions related to specific academic areas (i.e. rereading, erasing answers and counting objects or numbers). Conclusions These findings may help clinicians and researchers identify possible intervention strategies and supports based on the behavioural phenotype associated with genetic subtype in individuals with PWS.     

高中生应对方式及其与学业成绩的关系

目的:探讨高中生面对挫折和烦恼时应对方式的特点及其与学业成绩的关系。方法:以中学生应对方式评定问卷对649名高中生进行了调查。结果:女生比男生更倾向于采用发泄(因子均分2.4±0.7/2.7±0.7,F=23.32,P<0.01)和忍耐(3.2±0.7/3.0±0.8,F=5.08,P<0.05),而男生更倾向于采用幻想(2.4±0.9/2.1±0.8, F=15.52,P<0.01);重点中学比普通中学的高中生更多采用问题解决(3.3±0.6/3.1±0.7,F=20.85,P<0.011幻想(2.4±0.9/2.1±0.9,F=12.87,P<0.01)、退避(2.9±0.6/2.8±0.6,F=7.04,P<0.01)应对;来自城市和农村的高中生应对方式差异不显著;和睦安宁家庭气氛中的高中生采用问题解决应对显著多于偶尔争吵和经常争吵家庭中的高中生;民主型教养方式下的高中生比放任型教养方式的学生更多采用问题解决应对,权威型教养方式家庭中的高中生比民主型教养方式家庭中的高中生更多采用幻想应对。结论:高中生的应对方式存在性别差异。不同家庭气氛和不同教养方式以及学生在学业上的地位对应对方式也有一定影响,但城乡差别不明显。     

Neuropsychological Deficit and Academic Performance in Children and Adolescents Following Traumatic Brain Injury

Evaluated the utility of neuropsychological testing in predictingacademic outcome in children 1 year following traumatic braininjury (TBI). Fifty-one schoolage children who were admittedto hospital after TBI were assessed with a battery of neuropsychologicalmeasures at 3 months postinjury. Academic achievement was assessedat 3 and 12 months postinjury. The neuropsychological batteryincluded intelligence testing and measures of memory, learning,and speed of information processing. Academic outcome was assessedin terms of post-TBI changes in reading, spelling, and arithmetic;changes in teacher ratings of school performance; and changein school placement. According to logistic regression analysis,change in placement from regular to special education at 1-yearpost-TBI was predicted by injury severity and by neuropsychologicalperformance at 3 months post-TBI. Findings suggest that neuropsychologicaltesting is useful in identifying children with special educationalneeds subsequent to TBI.     

Problematic Methods in the Assessment of Scholarly Productivity in Clinical PhD Programs

We review the methods in the ranking of clinical psychology doctoral programs provided by Stewart, Roberts, and Roy (2007). Using our own program as an example, we identify several areas of concern (e.g., authorship credits, criteria applied, faculty attrition). The inaccuracies identified for our program ranking, in combination with methodological concerns highlighted by previous commentaries, suggest that the validity of the rankings can be called into question.

Universal School Meals and Associations with Student Participation,Attendance, Academic Performance,Diet Quality,Food Security,and Body Mass Index: A Systematic Review

The school environment plays an important role in children’s diets and overall health, and policies for universal free school meals have the potential to contribute to positive child health outcomes. This systematic review evaluates studies examining the association between universal free school meals and students’ school meal participation rates, diets, attendance, academic performance, and Body Mass Index (BMI), as well as school finances. The search was conducted in accordance with the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA). A search for studies published in economically developed countries published through December 2020 was performed in PubMed, Education Resources Information Center (ERIC), Thomson Reuters’ Web of Science, and Academic Search Ultimate, followed by examining the references in the resultant literature. A total of 47 studies were identified and the Newcastle-Ottawa Scale (NOS) was applied to assess bias. Nearly all studies examining universal free school meals found positive associations with school meal participation. Most studies examining universal free school meals that included free lunch found positive associations with diet quality, food security, and academic performance; however, the findings of studies examining only universal free breakfast were mixed. Research findings were similarly mixed when examining attendance as an outcome. Concerns about adverse outcomes on student BMI were not supported by the literature; in fact, several studies detected a potentially protective effect of universal free school meals on BMI. Research examining the impact of universal free meals on school finances was limited, but suggest that lower-income school districts in the U.S. may have positive financial outcomes from participation in universal free school meal provisions. Additionally, providing free meals to students may be associated with improved household incomes, particularly among lower-income families with children. Further research is needed to examine the financial implications of universal free meals for both school districts and families. Overall, universal free school meals may have multiple benefits for students and countries should consider universal free school meal provisions with strong nutrition guidelines.
