Validation française du Caregiving Strain Questionnaire sur une population de parents d’enfants avec troubles du spectre de l’autisme

The Caregiving Strain Questionnaire (CGSQ-21) allows the assessment of the burden of family caregivers. The objective of this study is to present a validation of a French translation of this questionnaire (FCGSQ-21) to parents of children with autism spectrum disorder (ASD). A literature review from 2002 to 2012 highlighted that five scales measured caregivers’ burden regarding children and only one English scale examined parents of children with ASD's burden. The CGSQ-21 was chosen for this study and has been validated with 167 French parents who completed an online survey. Those parents filled out a total of six questionnaires measuring optimism, perceived social support, care satisfaction, anxiety, depression and perceived burden. The factorial and convergent validities as well as the internal consistency of the FCGSQ-21 have been tested with an exploratory and confirmatory factor analysis (CFA). A three factors model was found to best fit the structure of this scale, those include the objective burden as well as the internalized and externalized subjective burdens. The convergent validity brings to light significant correlations between many scales of the protocol. In the present study, the FCGSQ-21's homogeneity is excellent with a Cronbach's alpha of 0.90. The FCGSQ-21 is a valid and useful tool to measure the burden perceived by parents of children with ASD. This study's objective was to confirm the tool's validity in order to improve clinical practice with children and their parents. This scale evaluates parents’ levels of burden perceived for the purpose of adapting interventions given to the children while taking into account parental well-being's specificities highlighted by the FCGSQ-21.     

The influence of sharing on children's initial concept of division.

We report three studies that investigate young children's ability to solve partitive division problems when presented with a concrete model of a problem. In the studies, 5- to 8-year-olds were given problems about sharing "sweets" between dolls, and the sweets were grouped in one of two different ways. When the sweets were grouped by the divisor, the number of groups coincided with the number of dolls (divisor) and the number in each group was the answer (quotient). When the sweets were grouped by the quotient, the reverse was true. In all three experiments, children found it much easier to solve the problems in the Grouping-by-Divisor condition than in the Grouping-by-Quotient condition (although there was some evidence of a developmental improvement in the tasks). It is suggested that the Grouping-by-Divisor condition is easier because it coincides with the end point of sharing. The findings are discussed with reference to schemas of action in children's mathematical understanding.     

父母学习陪伴与小学生学业不良的关系:亲子学业沟通的中介作用和学习负担的调节作用

采用父母学习陪伴问卷、亲子学业沟通问卷、学习负担量表和学业成绩自我评定量表对578名4-6年级小学生及家长进行调查,探讨父母学习陪伴与小学生学业不良的关系以及亲子学业沟通四个维度（成绩沟通、习惯沟通、态度沟通和方法沟通）的中介作用和学习负担的调节作用。结果发现：（1）父母学习陪伴对学业不良具有显著的负向预测作用;（2）亲子学业态度沟通和方法沟通在父母学习陪伴与学业不良的关系中起完全中介作用;（3）学习负担在亲子学业态度沟通与学业不良之间的调节作用显著。在低学习负担条件下,亲子学业态度沟通对学业不良的改善作用更为明显。本研究结果表明,提高父母学习陪伴的时间和陪伴质量、改善亲子学业沟通方式并适当降低学习负担,可能改善小学生的学业不良。     

A structural equation modeling approach for the acceptance of driverless automated shuttles based on constructs from the Unified Theory of Acceptance and Use of Technology and the Diffusion of Innovation Theory

The present study investigated the attitudes and acceptance of automated shuttles in public transport among 340 individuals physically experiencing the automated shuttle ‘Emily’ from Easymile in a mixed traffic environment on the semi-public EUREF (Europäisches Energieforum) campus in Berlin. Automated vehicle acceptance was modelled as a function of the Unified Theory of Acceptance and Use of Technology (UTAUT) constructs performance expectancy, effort expectancy, social influence, and facilitating conditions, the Diffusion of Innovation Theory (DIT) constructs compatibility and trialability, as well as trust and automated shuttle sharing. The results show that after adding the DIT constructs, automated shuttle sharing, and trust to the model, the effect of performance expectancy on behavioural intention was no longer significant. Instead, compatibility with current travel was the strongest predictor of behavioural intention to use automated shuttles. It was further found that individuals who are willing to share rides in an automated shuttle with fellow travelers (i.e., automated shuttle sharing) and who trust automated shuttles (i.e., trust) are more likely to intend to use automated shuttles (i.e., behavioural intention). The highest mean rating was obtained for believing that automated shuttles are easy to use, while the lowest mean rating was obtained for feeling safe inside the automated shuttle without any type of supervision. The analysis revealed a preference for the supervision of the automated shuttle via an external control room to the supervision by a human steward onboard. We recommend future research to investigate the hypothesis that compatibility could serve as an even stronger predictor of the behavioural intention to use automated shuttles in public transport than performance expectancy.     

Post-stroke depression as a predictor of caregivers burden of acute ischemic stroke patients in China

Our aim was to explore the independent attribution of Post-stroke depression (PSD) to caregiver burden of acute ischemic stroke patients. A cross-sectional survey was performed with 271 acute ischemic stroke patients in the Huai-He Hospital and First People’s Hospital of Kaifeng City in China. PSD was assessed by Self-rating Depressive Scale, and caregiver burden was assessed by Zarit Caregiver Burden Interview. Clustered logistic regression was applied to identify the impact of PSD on caregiver burden. As results, female patients, normal muscle strength and PSD were associated with caregiver burden. PSD correlated with an independent influence of 17.2% on the risk of caregiver burden, The independent influence of PSD on caregiver burden was smaller than that of social-demographics of caregivers and clinical factors of stroke patients This study suggests that PSD may have a modest influence on caregiver burden.     

Joint task switching

The present study investigates the representation of task-sets in a joint dual-task setting. To this end, a task-switching approach is used. Task switching is associated with a switch cost, which can be decomposed in several markers of task-set coordination. These markers can be used to investigate whether participants represent the co-actor's task-set in a joint dual-task setting. A joint task-switching procedure was used in which two participants performed a distinct task and the participants’ turn to respond could switch or repeat on a trial-by-trial basis. The results indicate that joint task switching also elicits a switch cost. However, this switch cost does not seem to be related to the representation of the co-actor's task-set. It is suggested that the switch cost observed in joint task switching is based on processes of task monitoring, which increase the saliency of task-irrelevant stimulus information.

Differences in caregiver behaviors of infants at-risk for autism and typically developing infants from 9 to 15 months of age

During an object sharing paradigm, we compared infant-caregiver interactions between two groups: i) infants at high-risk (HR) for being diagnosed with Autism Spectrum Disorder (ASD) and ii) low-risk (LR) infants, observed at 9, 12, and 15 months of age. 16 HR infants (14 infants with an older sibling diagnosed with ASD and 2 preterm infants that received a diagnosis of ASD at 2 years) and 16 LR infants (typically developing infants without older siblings diagnosed with ASD) were included in the study. At each visit, infants played with objects in the presence of their caregivers as crawlers or walkers. Previously, we found that HR infants are less likely to share their object play with caregivers at walker ages. The present study found that caregivers of HR infants used greater directive bids including being more proximal to infants and using greater verbal and non-verbal bids to sustain their infant’s attention and to ensure their compliance during the task compared to caregivers of LR infants. Our study emphasizes the bidirectional and dynamic nature of infant-caregiver interactions. Our findings have implications for caregiver training programs that teach parents appropriate strategies to promote early social communication skills in at-risk infants.     

Children's response biases to results of object sharing

This study investigated whether 2- to 6-year-old children exhibit a response bias to questions pertaining to the results of sharing objects that should attract their interest. An experimenter distributed four objects between herself/himself and a child, equally or unequally (more to the child or more to the experimenter) and asked the child yes-no questions: “Is this okay?” and “Is this bad?” The results indicated that 2- and 3-year-olds exhibited a yes bias in all conditions, 4-year-olds exhibited a yes bias to the equal condition and to the unequal condition with more distributed to the child, and 5-year-olds exhibited a yes bias to both unequal conditions, whereas 6-year-olds did not show any response bias. Young preschoolers exhibited a yes bias regardless of questions and children may become able to say both “yes” and “no” appropriately to questions about object sharing after the age of six.     

基于秘密分享的学前儿童对友谊关系的推断

秘密是隐藏在内心深处的东西,人们通常会与亲密的人分享和披露秘密。因此,追踪人们知道彼此的秘密可以作为社会关系的线索。本研究开展两个实验探究秘密分享对学前儿童推断友谊关系的影响。105名和60名幼儿分别参与实验1、实验2。实验1发现5岁以下的儿童大多数认为主角分享物质资源(玩具)的对象是主角的朋友,5～6岁的儿童大多数认为主角分享秘密的对象是主角的朋友,选择被分享秘密的人是分享者更可能的朋友的人数随着年龄的增长而增长; 实验2发现与分享积极的秘密信息和物质资源相比,大部分5～6岁的儿童更倾向于认为分享消极的秘密信息的双方存在友谊关系。研究结果说明至少5～6岁的儿童理解分享秘密的社会意义,并且5～6岁儿童把分享消极的秘密作为友谊关系更有力的标志。
