The role of executive functions in social impairment in Autism Spectrum Disorder

Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder characterized by socio-communicative impairments. Executive dysfunction may explain some key characteristics of ASD, both social and nonsocial hallmarks. Limited research exists exploring the relations between executive function and social impairment in ASD and few studies have used a comparison control group. Thus, the objective of the present study was to investigate the relations between executive functioning using the Behavioral Rating Inventory of Executive Functioning (BRIEF), social impairment as measured by the Social Responsiveness Scale (SRS), and overall autistic symptomology as measured by the Autism Diagnostic Observation Schedule (ADOS) in children and adolescents with and without ASD. Seventy children and adolescents diagnosed with ASD and 71 typically developing controls were included in this study. Findings showed that behavioral regulation executive processes (i.e., inhibition, shifting, and emotional control) predicted social function in all children. However, metacognitive executive processes (i.e., initiation, working memory, planning, organization, and monitoring) predicted social function only in children with ASD and not in typically developing children. Our findings suggest a distinct metacognitive executive function-social symptom link in ASD that is not present in the typical population. Understanding components of executive functioning that contribute to the autistic symptomology, particularly in the socio-communicative domain, is crucial for developing effective interventions that target key executive processes as well as underlying behavioral symptoms.     

Neuro-feedback intervention efficacy for treating children with Autism Spectrum Disorder

This study explored practitioners perceptions of a neuro-feedback intervention in treating children with Autism Spectrum Disorder’s (ASD). Informants were a convenience sample of ten South African neuro-feedback practitioners registered with the Health Professions Council of South Africa (HPCSA). The data on their views on neuro-feedback treatment efficacy, with children with ASD, were collected by means of semi-structured in-depth interviews. Thematic analysis of the data suggest practitioners to perceive neuro-feedback treatment to enhance the social, mood, behaviour, academic life, and family functioning of children with ASD. Additionally, the practitioners perceived neuro-feedback treatment to assist in reducing anxiety among children with ASD.     

Evaluating information processing in Autism Spectrum Disorder: The case for Fuzzy Trace Theory

Literature on the developmental trajectory of cognition in Autism Spectrum Disorders (ASD) presents several inconsistent findings. In this review, we focus on information processing, and specifically, the use of gist and verbatim representations to guide memory, reasoning, and concept formation. The added perspective of Fuzzy Trace Theory may help to resolve mixed results regarding the frequency, nature, and effectiveness of gist processing in ASD by providing established process models and tasks suitable for use in individuals at all levels of functioning. In order to demonstrate the utility of FTT to the field of ASD research, we present evidence from three complementary theories–Weak Central Coherence (WCC), Executive Function (EF), and Theory of Mind (ToM)–which have dominated the landscape to date. We discuss the potential utility of FTT tasks and process models, proposing testable hypotheses that address ambiguous or conflicting results in the current literature. Applying a theory of typical development to the study of ASD may add value to past and future research.     

Open-Trial Pilot of Parent-Child Interaction Therapy for Children With Autism Spectrum Disorder

In this pilot study, the effectiveness and feasibility of Parent-Child Interaction Therapy (PCIT) for decreasing disruptive behavior was evaluated in 17 young children with Autism Spectrum Disorder (ASD). PCIT is a behaviorally based play therapy which targets the parent-child relationship through live coaching of play interactions and the implementation of consistent discipline techniques. Following an average of 19 sessions, disruptive behavior as measured by multiple indices significantly decreased. Congruently, parents increased positive parental following skills and decreased negative parental leading skills across the course of treatment. In addition, parents reported increased levels of child functional communication and prosocial behavior. High levels of parent acceptability of the intervention were also noted. Effect sizes were medium to large across measured dependent variables, including parent report and behavioral observations. Implications for the clinical use of PCIT within an ASD population and future research with controlled outcome studies are discussed.     

Experiences of father carers of children with Autism Spectrum Disorder: An exploratory study

This study aimed to explore the carer experiences of fathers of children with Autism Spectrum Disorder (ASD). A total of eight South African fathers between the ages of 38 and 45 years were the interview informants. They cared for at least one child with ASD each and their children with ASD were within the age range of five to nine years (n=9, males=7, females=2, Low functioning=4, Moderately functioning=4, High functioning=1).The father carers completed a semi-structured interview. The data were analysed thematically. Four primary themes emerged from the analysis pertaining to aspects of rescoping their futures to include the care of a child with ASD, relationship issues, access to and management of resources, information and support, and carer compassion and satisfaction. The fathers shared a view that caring for their children with ASD was both stimulating and enriching, and that with time, they were able to adapt, and better respond, to the specific needs of their child.     

7～10岁自闭症谱系障碍儿童对情绪面孔的觉察与加工

为了考察自闭症谱系障碍(autism spectrum disorder,ASD)儿童对不同情绪面孔的觉察和加工情况,设计两个眼动实验任务,要求14名7～10岁ASD儿童和20名同年龄正常儿童观看图片。实验一采用将情绪面孔嵌入风景图片中引起语义不一致的刺激;实验二采用含有情绪面孔的无意义背景乱序图片刺激。结果发现:(1)ASD儿童对不同情绪面孔的觉察时间都显著长于正常儿童;(2)与正常儿童一样,ASD儿童表现出对恐惧面孔的注意偏向;(3)实验二中,ASD儿童对不同情绪面孔内部特征区的注意分配与正常儿童不同;正常儿童能注意最能展示该类情绪特征信息的区域,如恐惧的眼睛、愉快的嘴巴,而ASD儿童对三类情绪面孔特征区的注意分配方式相似;(4)两个实验条件下,ASD者对不同情绪面孔的觉察、加工模式与正常儿童相似。     

运用游戏观察评量自闭症谱系障碍儿童的探索研究

可否运用游戏观察来评量和区分ASD儿童的功能?这是一个全新的课题。本研究聚焦自由游戏和装扮游戏,对86名ASD幼儿进行了准实验观察研究。结果发现,在自由游戏中,功能越低的ASD儿童,其交流频率越少、跟说语言越多、个体自身的探究和创造性语言愈少。在装扮游戏中,功能越低的ASD儿童,其破坏性行为越多、象征意义游戏的发生频率越少,利用玩具进行装扮游戏的能力越低。由此可见,运用游戏观察评量和区分ASD儿童功能或可为有效方法。     

Effects of Group Functional Behavior-Based Cognitive-Behavioral Therapy for Obsessive-Compulsive Behavior in a Youth With Autism Spectrum Disorder

Individuals with Autism Spectrum Disorder (ASD) often present with comorbid Obsessive Compulsive Behaviors (OCBs), but little research exists on effective intervention for OCBs. Using a single-case experimental design, this study highlights the efficacy of a Group Functional Behavior-based Cognitive-Behavior Therapy (Fb-CBT) to reduce OCBs in an 11-year-old youth with ASD. Tailored to the individual needs of this youth, Fb-CBT included traditional CBT components (e.g., psychoeducation, cognitive-behavioral skills training, and exposure and response prevention) coupled with functional behavior assessment and intervention. Time-series parent report data and standardized measures showed clinically significant decreases in OCBs, an increase in psychosocial functioning, and high consumer satisfaction.     

CBT for Children and Adolescents With High-Functioning Autism Spectrum Disorders,edited by A. Scarpa,S. Williams White, & T. Attwood

ABSTRACT

Parent-Child Interaction Therapy (PCIT) is a manualized behavioral intervention originally developed by Eyberg (1988 Eyberg, S. (1988). Parent-child interaction therapy: Integration of traditional and behavioral concerns. Child &; Family Behavior Therapy, 10(1), 33–46. doi:10.1300/j019v10n01_04[Taylor &; Francis Online] , [Google Scholar]) to address disruptive behaviors in young children. Although previous research findings support the contention that components of PCIT would positively impact communication, behavior, and adaptive skills (Howard, Sparkman, Cohen, Green, &; Stanislaw, 2005; Lovaas, 1987 Lovaas, O. I. (1987). Behavioral treatment and normal educational and intellectual functioning in young autistic children. Journal of Consulting and Clinical Psychology, 55(1), 3–9. doi:10.1037/0022-006x.55.1.3[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]; Remington et al., 2007 Remington, B., Hastings, R. P., Kovshoff, H., Degli Espinosa, F., Jahr, E., Brown, T., &; Ward, N. (2007). Early intensive behavioral intervention: Outcomes for children with autism and their parents after two years. American Journal on Mental Retardation, 112(6), 418–438. doi:10.1352/0895-8017(2007)112[418:eibiof]2.0.co;2[Crossref], [PubMed] , [Google Scholar]) in children with developmental disabilities, few studies are shown in the literature. In a modified version of PCIT, caregivers completed two phases of intervention with their child diagnosed with Autism Spectrum Disorder (ASD). During the Child-Directed Interaction (CDI) phase, caregivers were taught to conduct mand training, follow-their child’s lead, provide attention for their child’s positive behaviors, and ignore their child’s negative behaviors. During the Parent-Directed Interaction (PDI) phase, caregivers were taught to give effective commands and follow through with demands. The goal of the current study was to determine whether children’s production of vocalizations increased after participation in a modified PCIT program. Data from two participants diagnosed with autism were included in the study. Outcomes of these two case studies show that both children displayed an increase in the total number of vocalizations emitted in the posttreatment observation relative to baseline. Additionally, caregivers of both participants displayed an increased number of positive behaviors in the posttreatment observation relative to baseline.     

自闭症谱系障碍者异常的大脑功能连接

自闭症谱系障碍(Autism spectrum disorders, ASD)是一种常见的神经发育障碍, ASD在社交、语言、行为等方面的障碍与其异常的大脑功能连接存在密切关系。与正常发育者相比, ASD大脑既表现出远距离功能连接不足, 也表现出局部功能连接过度增强。ASD这种异常的脑功能连接受到结构异常、扫描状态、个体发展、分析方法等多种因素的影响。未来的ASD脑机制研究中, 要综合分析脑功能与结构, 关注年龄发展变化, 并将任务状态、被试取样、数据分析标准等因素纳入考察。     

Impaired Consonant Trigrams Test (CTT) performance relates to everyday working memory difficulties in children with Autism Spectrum Disorders

Individuals with Autism Spectrum Disorders (ASD) often struggle with complex tasks, such as those requiring divided attention (simultaneously completing two independent tasks) that also place high demands on working memory. Prior research shows that divided attention is impaired in adults and children with ASD and is related to ASD and comorbid attention deficit/hyperactivity disorder (ADHD) symptoms, but the impact on everyday functioning is unclear. Because ADHD symptoms are associated with poor divided attention and working memory performance in children with ASD, we also examined ADHD symptoms as moderators of divided attention performance. We examined performance on the Consonant Trigrams Test (CTT) between high-functioning 8- to 13-year-olds with ASD (n?=?28) and typically developing controls (n?=?18) matched on age and IQ. In the ASD group, we also correlated performance with ADHD symptoms and behavior ratings of everyday working memory. CTT performance in children with ASD was significantly worse than in matched controls. A significant correlation between CTT performance and everyday working memory was observed, but CTT performance was not related to comorbid ADHD symptoms in the ASD group. Divided attention with high working-memory demands is a relative weakness in children with high-functioning ASD; this weakness relates to everyday functioning, and it is independent from ADHD symptoms. That ADHD symptoms are not associated with divided attention performance is inconsistent with one prior investigation, which likely results from using different divided attention tasks in the two studies.     

The Cultural Adaptation of a Transition Program for Latino Families of Youth with Autism Spectrum Disorder

During the transition to adulthood, effective and culturally relevant supports are critical for families of youth with autism spectrum disorder (ASD). There is a dearth of documented program development and research on supports for Spanish-speaking Latino families during this life stage. The present work describes the cultural adaptation process of an evidence-based transition program for Latino families of youth with ASD. A model of the actions necessary to meaningfully conduct a cultural adaptation in this context is described. After implementing the culturally adapted program titled Juntos en la Transición with five Spanish-speaking families, parents reported high social validity of the program through surveys and interviews. The cultural adaptation process followed in this work is important for the further development of programs that address the transition needs of Latino youth with ASD and their families. Our impressions may also be useful to those who aim to develop culturally sensitive and ecologically valid multifamily group intervention programs for families from cultural and linguistic minority groups.     

Relationships between autistic-like and schizotypy traits: An analysis using the Autism Spectrum Quotient and Oxford-Liverpool Inventory of Feelings and Experiences

To further investigate claims of a relationship between autism and schizophrenia, the current study examined the associations between specific dimensions of autistic-like and schizotypy traits. These traits were assessed using the Autism Spectrum Quotient and the Oxford-Liverpool Inventory of Feelings and Experiences. After using factor analysis to explore the dimensions of autistic-like and schizotypy traits represented in these measures in two separate groups of students (N₁ = 362, N₂ = 639), the relationships between these dimensions were examined. While the results are consistent with suggestions in the literature of an overlap in the interpersonal deficits associated with autism and schizophrenia, they offer little support for Crespi and Badcock’s (2008) claim that autism and positive schizophrenia are diametrically opposed disorders.     

自闭症谱系障碍儿童心理测评的回溯与探索

自闭症谱系障碍(ASD)儿童是一群已引起高度关注的群体,因其兼具社会发展、人际交流障碍等于一身,更因其中大部分儿童还伴有认知,言语发展和情绪障碍,对其进行心理测评是一个极为艰巨和重要的课题.本文从诊断性、认知性和教育干预三个方面对ASD儿童的心理测评进行了述评.同时还阐述了在此基础上建构"会聚式"、"分层式"和"分类式"ASD儿童心理测评体系之构想.     

Stepping Stones Triple P: An RCT of a Parenting Program with Parents of a Child Diagnosed with an Autism Spectrum Disorder

Whilst the Triple P Positive Parenting Program has a large evidence base (Sanders, Clinical Child and Family Psychology Review 2:71–90, 1999; Sanders, Journal of Consulting and Clinical Psychology 68:624–640, 2000) and preliminary evidence indicates that Stepping Stones Triple P is also efficacious (Roberts, Journal of Clinical Child and Adolescent Psychology, 35(2):180–193, 2006), to date Stepping Stones has not been evaluated with the ASD population. Fifty-nine families with a child with ASD aged between 2 and 9 participated in this randomized controlled trial. The results demonstrate significant improvements in parental reports of child behaviour and parenting styles with the treatment effects for child behaviour, parental over reactivity and parental verbosity being maintained at follow-up 6 months later. Further, the results suggest significant improvements in parental satisfaction and conflict about parenting as well as a sleeper effect for parental efficacy. The results indicate that Stepping Stones Triple P is a promising intervention for parents of children with ASD. Limitations and future research are also addressed.     

Indications of Resilience Factors in Families Who have Lost a Home in a Shack Fire

The aim of this study was to explore the presence of resilience factors in families living in an informal settlement on the outskirts of a rural town that have lost their homes in a shack fire. A mixed methods research design was utilised. Qualitative data were obtained through responses to an open‐ended question, and quantitative data were obtained through the completion of questionnaires by an adult representative of each of the 38 African families that were identified through convenience sampling. To identify resilience factors, content analyses (on the qualitative data) were performed and Spearman correlations (for the quantitative data) were calculated. The results show that supportive communication, a sense of being in control and having internal strengths and dependability, while working together as a family, are vital to the resilience of the families that took part in this study. Furthermore, material support from the municipality and extended family, shelter provided by members of the extended family, and financial support from the extended family were also indicated as essential in overcoming the crisis and being resilient.
