Group cognitive behavioural therapy program shows potential in reducing symptoms of depression and stress among young people with ASD

We examined the efficacy of cognitive behavioural therapy (CBT) delivered in groups on the reduction of symptoms of depression, anxiety and stress in young people on the autism spectrum. Utilising a quasi-experimental design, comparisons were made between individuals allocated to a group intervention program and individuals allocated to a waitlist. Following the intervention program, participants who were initially symptomatic reported significantly lower depression and stress scores on the Depression Anxiety Stress Scales in comparison to individuals on the waitlist. There was no significant change in anxiety related symptoms. The benefits were maintained at 3 and 9 month follow-up. Our findings demonstrate the potential of CBT in a small group setting for assisting young people with ASD who have symptoms of depression and stress.

The effects of a course of intranasal oxytocin on social behaviors in youth diagnosed with autism spectrum disorders: A randomized controlled trial

Background There is increasing interest in oxytocin as a therapeutic to treat social deficits in autism spectrum disorders (ASD). The aim of this study was to investigate the efficacy of a course of oxytocin nasal spray to improve social behavior in youth with ASD. Methods In a double-blind, placebo-controlled trial across two Australian university sites between February 2009 and January 2012, 50 male participants aged between 12 and 18 years, with Autistic or Asperger's Disorder, were randomized to receive either oxytocin (n = 26) or placebo (n = 24) nasal sprays (either 18 or 24 International Units), administered twice-daily for 8 weeks. Participants were assessed at baseline, after 4- and 8-weeks of treatment, and at 3-month follow-up. Primary outcomes were change in total scores on the caregiver-completed Social Responsiveness Scale and clinician-ratings on the Clinical Global Impressions-Improvement scale. Secondary assessments included caregiver reports of repetitive and other developmental behaviors and social cognition. Clinical trial registration: Australian New Zealand Clinical Trials Registry www.anzctr.org.au ACTRN12609000513213. Results Participants who received oxytocin showed no benefit following treatment on primary or secondary outcomes. However, caregivers who believed their children received oxytocin reported greater improvements compared to caregivers who believed their child received placebo. Nasal sprays were well tolerated and there was no evidence of increased side effects resulting from oxytocin administration. Conclusions This is the first evaluation of the efficacy for a course of oxytocin treatment for youth with ASD. Although results did not suggest clinical efficacy, further research is needed to explore alternative delivery methods, earlier age of intervention, and the influence of caregiver expectation on treatment response.

Virtual worlds for people with autism spectrum disorder: a case study in Second Life

PURPOSE: The purpose of this study is to explore the use of virtual worlds by people with autism spectrum disorder (ASD), with a particular focus on the virtual world Second Life™. METHOD: Case study methodology was selected to explore the experiences of Wolf, a participant with ASD, in Second Life. Wolf participated in three in-depth interviews. The interviews were analyzed using a content analysis to identify themes and sub-themes. RESULTS: Analysis identified four main themes: social factors and communication, empowerment, virtual world versus physical world, and social cues and body language. CONCLUSION: Anecdotally Wolf's experiences suggest that people with ASD enjoy using a virtual world and may feel more comfortable communicating in the virtual world context than the physical world. Virtual worlds offer a venue for people with ASD to be a part of a virtual society, lowers communication barriers experienced in the physical world, and gives the participant a unique opportunity to create and maintain friendships. Virtual worlds offer an arena for people with ASD to meet their peers on equal terms, not being dependent on social cues, which in the physical world can be a barrier for communication for this group. Further research in this area is required. Implications for Rehabiliation People with autism spectrum disorder enjoy using a virtual world and may feel more comfortable communicating in the virtual world context than the physical world. Virtual worlds offer a venue for people with autism spectrum disorder to be a part of a virtual society. Virtual worlds offer an arena for people with autism spectrum disorder to meet their peers on equal terms, not being dependent on social cues, which in the physical world can be a barrier for this group.

Discursos e práticas curriculares: um estudo dos métodos de ensino da leitura e da escrita no 1º ciclo do ensino básico: estudo de caso múltiplo

A presente tese de doutoramento tem por tema: “Discursos e práticas curriculares: um estudo dos métodos de ensino da leitura e da escrita no 1º ciclo do ensino básico. Estudo de caso múltiplo”. A investigação analisa compreensivamente, e de forma focalizada, as dificuldades de aprendizagem da leitura do interesse do investigador enquanto professor de crianças com essas dificuldades e pretende explorar a possibilidade de melhorar a aprendizagem da leitura e da escrita através da adequação do método de ensino. Selecionaram-se alunos de cinco escolas públicas do concelho da Ribeira Brava, Região Autónoma da Madeira, a frequentarem o 1.º ano de escolaridade. O estudo incide sobre oito casos diferentes, mas com o fator comum de experimentarem insucesso na aprendizagem da leitura e escrita. A partir da avaliação compreensiva dos oito casos estudados, utilizando o método de estudo de caso múltiplo, definiram-se os estilos individuais de aprendizagem para, a partir destes, adequar a metodologia de ensino da leitura e da escrita e observar os efeitos na aprendizagem. Os casos estudados tinham dificuldades de aprendizagem gerais e específicas. As dificuldades de aprendizagem gerais relacionavam-se com dificuldades de etiologia não especificada e as específicas eram do tipo dislexia, perturbação da atenção por hiperatividade, síndrome de Asperger, dificuldades no funcionamento intelectual e perturbação no desenvolvimento da linguagem. Apresentam-se as conceções dos professores sobre currículo, sobre o processo de aprendizagem da leitura e da escrita e as correspondentes práticas de ensino. Os professores participantes foram selecionados de forma a constituírem um grupo heterogéneo no que diz respeito à sua idade, anos de experiência e instituição de formação inicial. A investigação recorre à observação participante, à consulta documental e a entrevistas. O investigador utiliza o diário de bordo em complementaridade com a observação participante, no sentido de compreender o contexto e as significações dos participantes. Os resultados mostram os efeitos positivos do método de João de Deus na reeducação dos casos de dislexia, perturbação da linguagem e problemas no funcionamento intelectual. O método das 28 palavras revelou-se adequado na reeducação da leitura nos casos de défice de atenção, síndrome de Asperger e dificuldades de aprendizagem não especificadas.

Molecular and Cytogenetic Analyses on Brazilian Youths with Pervasive Developmental Disorders

The Pervasive Developmental Disorders (PDDs) constitute a group of behavioral and neurobiological impairment conditions whose main features are delayed communicative and cognitive development. Genetic factors are reportedly associated with PDDs and particular genetic abnormalities are frequently found in specific diagnostic subgroups such as the autism spectrum disorders. This study evaluated cytogenetic and molecular parameters in 30 youths with autism or other PDDs. The fragile X syndrome was the most common genetic abnormality detected, presented by 1 patient with autism and 1 patient with PPD not-otherwise specified (PPD-NOS). One girl with PDD-NOS was found to have tetrasomy for the 15q11-q13 region, and one patient with autism exhibited in 2/100 metaphases an inv(7)(p15q36), thus suggesting a mosaicism 46,XX/46,XX,inv(7)(p15q36) or representing a coincidental finding. The high frequency of chromosomopathies support the hypothesis that PDDs may develop as a consequence to chromosomal abnormalities and justify the cytogenetic and molecular assessment in all patients with PDDs for establishment of diagnosis.

Progettazione e implementazione di una applicazione per dispositivi mobili basata su piattaforma android (linguaggio java) a supporto di soggetti affetti da disturbi dello spettro autistico

Nella maggior parte dei casi, i soggetti affetti da Disturbo dello Spettro Autistico hanno un deficit di comunicazione, sia esso verbale o non verbale. Nonostante, ad oggi, non esista una cura per questo disturbo, una diagnosi precoce entro il terzo anno di vita del soggetto e un programma educativo coerente con le necessità del paziente, permettono al bambino con autismo di raggiungere quantomeno le abilità comunicative di base. Recenti studi hanno dimostrato che l’utilizzo di Information and Communication Technology (ICT) nel trattamento di soggetti affetti da Disturbo dello Spettro Autistico può portare molti benefici, dato che, da un lato, computer, tablet e smartphone sono strumenti strutturati e prevedibili e, dall’altro, i sintetizzatori vocali, se presenti, sono privi di inflessioni verbali. A questo proposito, durante il mio tirocinio di tesi magistrale presso l’azienda “CSP – Innovazioni nelle ICT” di Torino, ho sviluppato un’applicazione per tablet Android che permette a psicologi, educatori, logopedisti, insegnanti e genitori di creare tabelle comunicative circostanziate alle esigenze del soggetto e che consente a quest’ultimo di utilizzare questo strumento come efficace mediatore sociale. Questo software si va a inserire in un progetto più ampio, denominato “tools4Autism”, nato dalla collaborazione tra il centro di ricerca di cui sopra, la “Fondazione ASPHI Onlus – ICT per migliorare la qualità di vita delle persone con disabilità” e il “Centro Autismo e Sindrome di Asperger” di Mondovì (CN). L’applicazione prevede principalmente due metodi di utilizzo: il primo, definito “modalità operatore”, è un editor che permette di creare tabelle composte da un numero variabile di immagini che possono essere pittogrammi, fotografie personali, disegni del bambino e possono essere accompagnate o meno da un testo. Una volta create le tabelle, l’operatore ha la possibilità di modificarle, eliminarle, variarne l’ordine, esportarle su altri dispositivi o importare tabelle precedentemente create. Il secondo metodo di utilizzo, definito “modalità utente”, permette al soggetto affetto da Disturbo Autistico di comunicare con altre persone sfruttando le tabelle create dall’operatore coerentemente con le sue necessità. Al tocco dell’immagine da parte del bambino, essa viene evidenziata tramite un contorno rosso e, se abilitato, il sintetizzatore vocale riproduce il testo associato a tale immagine. I principali fattori di innovazione dell’applicazione sono la gratuità, la semplicità di utilizzo, la rapidità nella creazione e nell’aggiornamento delle tabelle comunicative, la portabilità dello strumento e l’utilizzo della sintesi vocale. Il software sarà sperimentato presso il “Centro Autismo e Sindrome di Asperger”, centro di neuropsichiatria infantile specializzato nello studio del Disturbo Autistico. Tale sperimentazione si pone come obiettivo quello di verificare gli effettivi miglioramenti nella velocità e nella qualità di apprendimento delle fondamentali abilità comunicative.

The development and evaluation of a computer-based program to test and to teach the recognition of facial affect

Autism is a chronic pervasive neurodevelopmental disorder characterized by the early onset of social and communicative impairments as well as restricted, ritualized, stereotypic behavior. The endophenotype of autism includes neuropsychological deficits, for instance a lack of "Theory of Mind" and problems recognizing facial affect. In this study, we report the development and evaluation of a computer-based program to teach and test the ability to identify basic facially expressed emotions. 10 adolescent or adult subjects with high-functioning autism or Asperger-syndrome were included in the investigation. A priori the facial affect recognition test had shown good psychometric properties in a normative sample (internal consistency: rtt=.91-.95; retest reliability: rtt=.89-.92). In a prepost design, one half of the sample was randomly assigned to receive computer treatment while the other half of the sample served as control group. The training was conducted for five weeks, consisting of two hours training a week. The trained individuals improved significantly on the affect recognition task, but not on any other measure. Results support the usefulness of the program to teach the detection of facial affect. However, the improvement found is limited to a circumscribed area of social-communicative function and generalization is not ensured.

Complex syntax in autistic spectrum disorders: A study with relative clauses

Background The few studies that have evaluated syntax in autism spectrum disorder (ASD) have yielded conflicting findings: some suggest that once matched on mental age, ASD and typically developing controls do not differ for grammar, while others report that morphosyntactic deficits are independent of cognitive skills in ASD. There is a need for a better understanding of syntax in ASD and its relation to, or dissociation from, nonverbal abilities. Aims Syntax in ASD was assessed by evaluating subject and object relative clause comprehension in adolescents and adults diagnosed with ASD with a performance IQ within the normal range, and with or without a history of language delay. Methods & Procedures Twenty-eight participants with ASD (mean age 21.8) and 28 age-matched controls (mean age 22.07) were required to point to a character designated by relative clauses that varied in syntactic complexity. Outcomes & Results Scores indicate that participants with ASD regardless of the language development history perform significantly worse than age-matched controls with object relative clauses. In addition, participants with ASD with a history of language delay (diagnosed with high-functioning autism in the DSM-IV-TR) perform worse on subject relatives than ASD participants without language delay (diagnosed with Asperger syndrome in the DSM-IV-TR), suggesting that these two groups do not have equivalent linguistic abilities. Performance IQ has a positive impact on the success of the task for the population with ASD. Conclusions & Implications This study reveals subtle grammatical difficulties remaining in adult individuals with ASD within normal IQ range as compared with age-matched peers. Even in the absence of a history of language delay in childhood, the results suggest that a slight deficit may nevertheless be present and go undetected by standardized language assessments. Both groups with and without language delay have a similar global performance on relative clause comprehension; however, the study also indicates that the participants with reported language delay show more difficulty with subject relatives than the participants without language delay, suggesting the presence of differences in linguistic abilities between these subgroups of ASD.

A ESCOLA INCLUSIVA ESTÁ POSTA, E AGORA?

O ambiente escolar é muito rico de histórias, de momentos, de aprendizados e de experiências. Todo professor sempre tem muito a contar. A diversidade de pessoas nesse universo faz com que tenhamos um cotidiano escolar sem rotinas, sem limites para a criatividade. Quando se depara com algo novo ou inesperado, o professor parece se transformar num agente inovador; conquistar o espaço, a situação de maneira a dominá-la e, nas mais variadas oportunidades, surpreender com estratégias enriquecedoras. Nesta pesquisa temos a oportunidade de compartilhar vivências únicas e singulares que possibilitaram contribuir para as já existentes no campo do fazer pedagógico com alunos com necessidade educacionais especiais. Experiências frustrantes também ocorrem no espaço escolar, porém na busca por dar a voz ao professor que desempenha o atendimento educacional especializado, relatamos aqui as experiências de sucesso. Com isso registramos a contribuição de um colégio da rede particular de ensino que tem como uma de suas metas a educação para todos.

Cognición no social y neuroimagen en TEA sin discapacidad intelectual

La presente tesis doctoral está constituida por tres estudios independientes pero relacionados entre sí: 1) Estimation of the intelligence quotient using Wechsler intelligence scales in children and adolescents with Asperger syndrome (SA), 2) Executive function is affected in autism spectrum disorder, but does not correlate with intelligence, y 3) Reduced gyrification is related to reduced interhemispheric connectivity in autism spectrum disorders. El objetivo general es estudiar las alteraciones cognitivas en niños y adolescentes con un Trastorno del Espectro Autista (TEA) sin discapacidad intelectual (SDI) asociada, particularmente en cuanto a sus aspectos en funcionamiento general (puntuaciones en escala de inteligencia Wechsler) y funciones ejecutivas, y estudiar la girificación y conectividad en el córtex prefrontal teniendo en cuenta su relación con las funciones ejecutivas. Como objetivos específicos: i) Medir los perfiles de inteligencia en niños y adolescentes con SA; ii) Evaluar la validez de cinco formas abreviadas de las escalas Wechsler de inteligencia en niños y adolescentes con SA, frente a la versión completa, teniendo en cuenta los criterios propuestos por Resnick & Entin, (1971); iii) Evaluar las funciones ejecutivas en una muestra homogénea de niños y adolescentes con TEA-SDI y comparar sus puntuaciones con las obtenidas por un grupo de niños y adolescentes sanos pareados por edad, años de educación, sexo, estatus socioeconómico y cociente intelectual (CI); iv) Evaluar si los déficits en funciones ejecutivas correlacionan con déficits en inteligencia general; v) Evaluar si los déficits en funcionamiento ejecutivo en los niños y adolescentes con TEA-SDI correlacionan con su nivel de funcionamiento o con la gravedad de los síntomas que presentan; vi) Estudiar la relación entre girificación y conectividad de la sustancia blanca, prestando especial atención a los cambios relacionados con la edad en una muestra de pacientes con TEA de alto funcionamiento; vii) Estudiar la girificación y conectividad en el córtex prefrontal teniendo en cuenta su relación con las funciones ejecutivas; y viii) Replicar los resultados obtenidos en nuestra muestra con los datos procedentes de una base independiente de niños y adolescentes con autismo de alto funcionamiento (Autism Brain Imaging Data Exchange, ABIDE)...

Control of Redundant Joint Structures Using Image Information During the Tracking of Non-Smooth Trajectories

Visual information is increasingly being used in a great number of applications in order to perform the guidance of joint structures. This paper proposes an image-based controller which allows the joint structure guidance when its number of degrees of freedom is greater than the required for the developed task. In this case, the controller solves the redundancy combining two different tasks: the primary task allows the correct guidance using image information, and the secondary task determines the most adequate joint structure posture solving the possible joint redundancy regarding the performed task in the image space. The method proposed to guide the joint structure also employs a smoothing Kalman filter not only to determine the moment when abrupt changes occur in the tracked trajectory, but also to estimate and compensate these changes using the proposed filter. Furthermore, a direct visual control approach is proposed which integrates the visual information provided by this smoothing Kalman filter. This last aspect permits the correct tracking when noisy measurements are obtained. All the contributions are integrated in an application which requires the tracking of the faces of Asperger children.
