A Comparison of Observation Systems for Monitoring Engagement in an Intervention Program

Linden, April D. 05 1900 (has links)
The measurement of engagement, or the interaction of a person with their environment, is an integral part of assessing the quality of an intervention program for young children diagnosed with autism spectrum disorder. Researchers and practitioners can and do measure engagement in many ways on the individual and group level. The purpose of this methodological study was to compare three commonly used recording systems: individual partial interval, group momentary time sampling, and group partial interval. These recording methods were compared across three classes of engagement: social, instructional, and non-instructional in a clinical setting with children with autism. Results indicate that group measurement systems were not sensitive to individual changes in engagement when child behaviors were variable. The results are discussed in the context of behavior analytic conceptual systems and the relative utility and future research directions for behavior analytic practice and research with young children in group settings.

Effects of Relational Teaching on the Language Development for Children with Autism Spectrum Disorder

Zhang, Wenhui January 2023 (has links)
Through two presented experiments, I investigated the relationship between the development of non-arbitrary relational control on a) degree of incidental acquisition of both the listener and speaker components of naming (Inc-BiN), b) arbitrary derived relations, and 3) joint attention for children diagnosed with autism spectrum disorder (ASD). In Experiment I, three preschoolers with ASD or developmental disabilities were selected based on their incidental acquisition of the listener component of naming (Inc-UniN). The study explored the effect of non-arbitrary relational teaching across the frames of coordination, distinction, comparison, opposition, and hierarchy on the degree of Inc-BiN for familiar and novel stimuli under the brief condition (Inc-BiN) and the number of correct responses on taught and novel non-arbitrary relations during the pre- or post-intervention probes using a concurrent multiple probes design. All three participants successfully acquired the discriminative function of contextual cues across the five frames for non-arbitrary relations. However, there was no improvement in the degree of Inc-BiN across all three participants. In Experiment II, three new preschoolers who demonstrated Inc-UniN with familiar and novel stimuli at the onset of the study went through the non-arbitrary listener/speaker MEI procedure across different frames to improve their abilities to derive arbitrary relations for coordination, distinctive, and comparison relations, advance the degree of the Inc-BiN with familiar and novel stimuli, and facilitate joint attention skills through a concurrent multiple probe design. The results showed a functional relationship between the non-arbitrary listener/speaker MEI procedure and the participants’ correct listener and speaker responses during derived arbitrary relational assessments across different frames. However, there was no effect on the degree of Inc-BiN or joint attention responses across all three participants after the intervention.

Computer Assisted Instruction to Improve Theory of Mind in Children with Autism

Eason, Lindsey R. 12 1900 (has links)
Children with autism spectrum disorder (ASD) show significant deficits in communication, emotion recognition, perspective taking, and social skills. One intervention gaining increased attention is the use of computer assisted instruction (CAI) to teach social, emotional and perspective-taking skills to individuals with ASD with the purpose of improving theory of mind skills. This study evaluated the effectiveness of CAI for improving theory of mind skills in four children with high functioning autism ages 5 to 12 years. A single-subject multiple baseline research design across participants was utilized to evaluate the effectiveness of CAI. The software contained 22 instructional scenarios that asked participants to identify emotions of characters based on situational cues displayed in line drawn pictures and audio feedback for correct and incorrect responses. Mind-reading skills were assessed using ten randomly selected scenarios for various emotions and no audio feedback. Visual analysis of the data revealed that all four participants increased mind-reading skills during the CAI condition. Additionally, this study evaluated levels of task engagement during experimental conditions. Three of the four participants showed an increase in task engagement during CAI compared to paper-based social stories used during baseline. Generalization of skills was assessed through the use of social scenarios acted out by family members of participants. All four participants were able to correctly identify emotions displayed in generalization scenarios. Results demonstrated that CAI was an effective and socially viable method for improving ToM skills in children with autism and they could generalize their skills to untrained settings.

Effectiveness of modeling and rehearsal to teach fire safety skills to children with autism

Unknown Date (has links)
Autism is a disorder that affects children at an alarming rate. One out of every 88 children is diagnosed with autism in the United States. The disorder is characterized by communication, social, and behavioral deficits. Children with autism often require specialized teaching methods to learn basic skills that most children acquire without specialized instruction. Relatively few studies have examined strategies for teaching safety skills to individuals with autism. The current study utilized a multiple baseline across participants’ design to evaluate whether a modeling and rehearsal strategy is effective for teaching fire safety skills to children with autism between 4 and 5 years of age. Results indicated that modeling and rehearsal were effective in teaching fire safety skills, the skills generalized to novel settings, and maintained 5-weeks following the completion of training. Implications for safety skill instruction and future research are discussed. / Includes bibliography. / Dissertation (Ph.D.)--Florida Atlantic University, 2013.

After the implementation of this Law, children with autism have been increasingly exposed to academic content in regular classrooms, and teachers have become increasingly unprepared. Considering those difficulties, the present research aimed to teach a teacher and two trainees from a private school in São Paulo, Brazil, to apply discrete trials of motor imitation to a child with ASD. The teaching was composed of three components of Basic Skill Training (BST): theoretical instruction, video modeling and practice with feedback. The baseline consisted of evaluating the teacher’s and trainees’ performance in applying nine items of discrete attempts in a controlled environment to the experimenter, who played the role of a child with autism. The generalization was measured in a task of conditional discrimination, also applied to the experimenter. The results showed that, after teaching, all the participants were able to apply the discrete trials correctly. The theoretical instruction component did not change the performance in the application. Video modeling and practice with feedback were the responsible items for the change in the participants’ performance, the latter producing a more significant change / No Brasil, em 2012, foi criada a Política Nacional de Proteção dos Direitos da Pessoa com Transtorno do Espectro Autista (TEA), com a sanção da Lei nº 12.764. Após a implementação da Lei, as crianças com autismo ficaram cada vez mais expostas a conteúdos acadêmicos nas salas de aula regulares, e os professores, cada vez mais despreparados. Considerando essas dificuldades, a presente pesquisa pretendeu ensinar uma professora e duas estagiárias de uma escola particular de São Paulo, SP, a aplicar tentativas discretas de imitação motora em uma criança com TEA. O ensino foi composto de três componentes do Basic Skill Training (BST): instrução teórica, videomodelação e prática com feedback. A linha de base consistiu na avaliação do desempenho da professora e das estagiárias em aplicar nove itens de tentativas discretas, em ambiente controlado, na experimentadora, que fazia o papel de uma criança com autismo. A generalização foi medida em uma tarefa de discriminação condicional, também aplicada na experimentadora. Os resultados mostraram que, após o ensino, todas as participantes conseguiram aplicar as tentativas discretas de forma correta. O componente de instrução teórica não alterou o desempenho na aplicação, e os itens responsáveis pela mudança foram a videomodelação e a prática com feedback, sendo que o último produziu uma mudança mais significativa no desempenho das participantes

Relations between age, autism severity, behavioral treatment and the amount of time in regular education classrooms among students with autism

Talib, Tasneem L. 21 July 2012 (has links)
Under federal law, students with disabilities have the right to be educated in classrooms with students without disabilities. For students with autism, social, communication, and behavioral deficits make inclusion difficult. The severity of deficits change over time, and therefore, so too do the effects of these deficits upon inclusion. Although most research indicates autism symptoms improve with age, some studies suggest symptoms worsen, thereby affecting classroom placement. Students with autism use a multitude of interventions, most of which are not evidenced-based. Behavioral interventions are among the small number of treatments that can decrease autism severity and foster inclusion. However, behavioral interventions have not been compared to other widely used treatments, and in practice, they are rarely used in isolation. The purpose of the present study was threefold. First, relations between age, and autism severity were examined. Second, the study investigated whether relations between autism severity and time spent in regular education classrooms differed according to age. Third, it investigated types of treatments students used, and whether using behavioral treatments moderated relations between age, autism severity and amount of time in regular education classrooms. Using a national database (Interactive Autism Network), data about the severity of social, communication and behavior deficits, treatment type, and amount of time spent in regular education classrooms were extracted from school-age students (n = 2646) with autism. The results of the study showed that as age increased, social deficits increased. Furthermore, younger students, and students with more severe social impairment spent less time in regular education classrooms. Age also predicted use of behavioral treatment, and students who used behavioral treatment spent more time in special education classrooms. The findings of this study reflect the current climate of autism knowledge, which emphasizes early, intensive intervention. Consequently, students who were younger, and used behavioral treatments, were likely to be in special education classrooms that could maximize individualization, and associated treatment benefits. This is important, as social deficits increase with age, and reduce the amount of time students spend in inclusive classrooms. Additional studies are needed to further understand how behavioral treatment, compared to or used in conjunction with other commonly used treatments, affects inclusion. / Department of Educational Psychology

The Effects of Differential Outcomes on Audio-Visual Conditional Discriminations in Children with ASD

Wiist, Catherine E. C. 05 1900 (has links)
The differential outcomes effect (DOE) refers to an observed increase in rates of acquisition of simple or conditional relations when the contingencies of reinforcement arrange for reinforcers to be uniquely correlated with a particular stimulus or response relative to conditions where the reinforcers are not uniquely correlated with either stimulus or response. This effect has been robustly documented in the literature with nonhuman subjects. This study asked whether the DOE would be observed with children with autism spectrum disorder (ASD) learning audio-visual conditional relations. Two participants learned two sets of 3 audio-visual conditional relations. For one set, the training conditions arranged for each of the three conditional relations to be uniquely correlated with a particular reinforcing stimulus (the DO condition). For the second set, the training conditions arranged for the same reinforcer to be used for all three audio-visual conditional relations (the NDO condition). Early results show that audio-visual conditional relations were acquired faster under the DO condition relative to the NDO outcomes condition (accuracy in DO condition was 30.8% higher on average than in NDO condition). These data suggest that differential outcomes should be more thoroughly investigated with children with diagnoses of ASD.

Elevated Attention Problems and Observed Parenting in a Sample of Preschoolers with Autism Spectrum Disorder

Kangas-Dick, Kayleigh January 2021 (has links)
Background. The experience of parenting children with Autism Spectrum Disorder (ASD) is generally understood to encompass higher levels of parenting stress relative to families of typically developing children and, in many instances, when viewed in comparison to children with other disabilities. Emerging evidence suggests that when children with ASD present with elevated attention problems, parents may be more likely to engage in harsh parenting during dyadic interactions (Donnelly, 2015). Despite this, few studies have examined the relationship between attention problems and observed parenting in families of children with ASD, which has been well-described in the literature as a particularly challenging context for parents. This dissertation investigated the relationship between child attention and observed parenting behaviors in a community sample of mothers of children with ASD in early childhood. The extent and nature of this relationship was further explored by observing whether parenting stress and depression played a role in mediating this relationship, and by investigating whether the relationship varied by child behavior and level of functioning. Parenting behaviors were directly observed across three dyadic tasks selected to approximate naturalistic situations in which parents and their children interact. It was hypothesized that increased attention problems would be linked to greater parenting stress, decreased positive parenting, and increased harsh parenting. Increased understanding of how attention problems relate to parenting within an ASD population will inform the selection and design of interventions uniquely suited to meet the needs of children and their families. Methods. This sample of 42 mother-child dyads included children with ASD attending a specialized preschool, where they received Applied Behavior Analysis educational programming. Child participants ranged in age from two years, six months to five years, six months, and all diagnostic classifications were corroborated through the Autism Diagnostic Observation Schedule, Second Edition (Lord et al., 2012). Parent and child behaviors during dyadic interactions were video recorded and then coded using the Psychological Multifactor Care Scale — ASD Adapted Preschool Version (Brassard, Donnelly, Hart, & Johnson, 2016). These direct observations of parent and child behavior were used to examine quality of parenting, child negativity toward the mother, and child engagement in tasks during parent-child interactions. Following the interaction, mothers completed a number of self-report measures assessing demographic characteristics, Parenting Stress Index, Fourth Edition, Short Form (PSI-4: SF; Abidin, 2012, maternal depressive symptoms on the PHQ9 (Kroenke, Spitzer, & Williams, 2001), and the Attention Problems scale on the Child Behavior Checklist (Achenbach & Rescorla, 2001). Classroom teachers completed the Communication domain of the Vineland Adaptive Behavior Scales –Third Edition (Vineland-3; Sparrow, Cicchetti, & Saulnier, 2016). Results. Children with ASD and clinically elevated attention problems (n = 19) had signifiantly lower verbal ability, more CBCL aggression, and their mothers reported signficantly more stress than children with ASD only (n = 23). Observed child engagement was significntly correlated with CBCL attention problems in the overall sample (r = -.42, p<.01), although the groups (ASD only v. ASD plus elevated attention problems) did not differ significantly (p < .06). Increased attention problems were significantly negatively related to positive parenting in this sample, even when ASD severity and verbal ability were controlled. Although a mediation model failed to support a model where attention problems predicted differences in observed parenting through parenting stress, reverse models showed increased positive parenting predicted decreased child attention problems through its effect on parenting stress. The role of maternal depressive symptoms as a mediator of this relationship was unsupported. Perhaps unsurprisingly, observed child behavior was found to be an important factor in understanding parenting behavior; however, the nature of its role was multifaceted. While observed child negativity was directly linked to lower levels of positive parenting, it moderated the relationship between child attention problems and harsh parenting, as mediated by parenting stress. In particular, attention problems were positively linked to greater stress, but this stress was more likely to be accompanied by a greater increase in harsh parenting behavior when children demonstrated negativity toward their mothers. The relationship between child attention problems and positive parenting varied by child verbal ability. For children with higher verbal ability, attention problems were linked to a drop in positive parenting, while this relationship was unsupported in children with underdeveloped communication skills. Conclusions. Child attention problems are a powerful predictor of parenting stress and less positive parenting. While it was expected that variation in attention problems would predict differences in parenting, reverse models showed more promise in identifying and defining the relationship between these variables, where mothers who exhibited more harsh parenting and less positive parenting experienced higher levels of parenting stress and their children demonstrated increased attentional problems and decreased engagement during dyadic interactions. The strength of this relationship varied according to observed child negativity and level of functioning. Clinical implications for practitioners and future directions for research investigating parenting children with ASD are discussed.

A Comparison of Fixed- and Variable-Ratio Token Exchange-Production Schedules with Children with Autism Spectrum Disorder

McNeely, Mitchell P 12 1900 (has links)
The token economy is a widely used and versatile motivational system within applied behavior analysis. Moreover, token reinforcement procedures have been shown to be highly effective in the treatment of children with autism spectrum disorder (ASD). In the experimental analysis of behavior, token reinforcement contingencies are conceptualized as three interconnected schedule components: (1) the token-production schedule, (2) the exchange-production schedule, and (3) the token-exchange schedule. Basic work with nonhuman subjects has demonstrated that the exchange-production schedule is the primary driver of performance in these arrangements, and that variable-ratio exchange-production results in reduced pre-ratio pausing and greater overall rates of responding relative to fixed-ratio exchange-production schedules. However, little applied research has been conducted to assess the generality of these findings within applied settings. The purpose of this study was to determine if fixed- and variable-ratio token exchange-production schedules would exert differential effects on pre-ratio pausing and overall rates of responding for three children with ASD during a free-operant sorting task. The results showed that pre-ratio pausing and overall rates of responding were not differentially effected by the fixed- and variable-ratio exchange-production schedules. Discrepancies between the experimental work and the current study are discussed along with additional limitations.

Incredible Years®-ASLD-Telehealth Pilot Study: Supportive Therapist Verbalizations and Change in Maternal Well-Being

Ajodan, Eliana January 2024 (has links)
Background. Mothers of children with Autism Spectrum Disorder (ASD) report high levels of stress, depression, and poor well-being, with little sense of social support due to the high demands of their child’s care. The Incredible Years® for Autism and Language Delays (IY-ASLD) program offers a unique model in that there is a dual focus on both child and parent outcomes. However, there is a dearth of literature on whether IY-ASLD can improve parental mental health outcomes. While there is some evidence to suggest that in-vivo therapist-to-parent supportive statements reduce parental resistance to treatment, there remains a gap in the literature regarding whether these behaviors directly impact parental mental health outcomes. Therefore, the present study investigated the degree to which exposure to the IY-ASLD telehealth curriculum (total minutes in attendance across sessions) along with in-vivo therapist-parent group verbal support was related to parental mental health outcomes and parental verbal approval statements of the child at post-treatment after controlling for baseline mental health and verbal approval. Methods. Participants were seventeen mother-child dyads, with children ages 2-years-8-months to 5-years-old recruited from a preschool utilizing an Applied Behavior Analysis (ABA) approach to schooling. All or virtually all children referred to this school by their school district are at-risk for or have been diagnosed with ASD. All of the children had an IEP or IFSP with mandated speech services, 71% of the children met criteria for ASD (N = 12) on the Childhood Autism Rating Scale- 2-SF, and 2/3 of the sample had adaptive behavior composites below a standard score of 70 on the Vineland Adaptive Behavior Scales- Third Edition Comprehensive Teacher Form (Sparrow et al., 2016). Participants were assigned to one of four treatment groups based on language level of the child and convenience of the group meeting time. Groups met for 12-weekly IY-ASLD sessions via telehealth. Data were collected at the beginning, mid-point, and end of treatment in the form of a parent questionnaire covering demographics, parental well-being (World Health Organization- Five Well-Being Index; WHO, 1998), depressive symptoms (Patient Health Questionnaire; Kroenke et al., 2001), and parenting stress (Parenting Stress Index-Fourth Edition, Short Form; Abidin, 2012). At post-treatment, parents reported satisfaction with the IY-ASLD-T program (IY-ASLD Parent Program Satisfaction Questionnaire). Data were also collected throughout treatment by recording IY-ASLD parent sessions. From the recorded parent sessions, two primary variables were developed. The first was treatment dosage, calculated as the total minutes each parent attended over the course of the 12-week intervention. The second was exposure to supportive therapist verbalizations during the first 10-minutes of each session, which was coded using the Therapy Process Code (TPC) to measure therapist supportive verbalizations during therapist-parent interaction (Chamberlain et al., 1986). Additionally, data were collected via a virtual parent-child play session (PCI) at the beginning, mid-point, and end of treatment, and later coded using the Verbal Behavior Developmental Language Coding System (VBDT) to measure parental verbal approval to child (Greer & Ross, 2008). Results. Mothers in this study had low levels of depression (PHQ-9; M = 4.59, SD = 4.69), average parenting stress (PSI-4-SF; M = 78.12, SD = 23.78), and low levels of well-being (WHO-5; M = 12.82, SD = 4.47). There were no statistically significant changes in parental depression, parental stress, or observed verbal approval from pre- to post-treatment and the effect sizes were small based on the partial eta squared and Kendall’s W values as per Cohen’s (1988, 1994) guidelines (small = .20-.49, medium = .50-.79, large > .80). However, there was a statistically significant change in caregiver well-being from baseline, mid-treatment, to post-treatment and a small effect size based on Kendall’s W (W = .31). A Friedman test indicated that caregivers demonstrated significant improvements in well-being from baseline to mid-treatment, and the improvement remained at post-treatment, χ2 (2) = 10.04, p < .01. There was no significant relationship between treatment dosage or supportive verbalizations and change in caregiver well-being. There was a significant negative correlation between treatment dosage and well-being at mid-treatment (r = -.493, p = .044), trending in the same direction at post-treatment (r = -.369, p = .146), possibly suggesting that parents with lower well-being, and therefore in greater need of support, attended IY-ASLD more frequently. An additional unexpected finding indicated that parents who were exposed to more supportive verbalizations had statistically significantly lower well-being at post-treatment. One explanation proposed by the authors is that parents who had lower well-being, and attended IY-ASLD sessions more frequently, received more supportive therapist verbalizations, possibly because they pulled for supportive verbalizations from the therapist. Results from the Incredible Years satisfaction questionnaire indicated there was high satisfaction with the program and the group leaders. High ratings of satisfaction with the group leaders and the program overall indicated that group leaders in the program may have successfully accomplished providing a “good enough” sense of support and reinforcement to parents over the course of the intervention. Therefore, it’s possible that specific therapist-to-parent supportive verbalizations were less related to improvements in parental well-being, and rather, the overall sense of support from the therapist to the parents in the group, along with support between the parents in the group, were sufficient to result in improvements in maternal well-being over the course of the intervention. Conclusions. Over the course of the IY-ASLD-T intervention, mothers demonstrated significant improvements in their overall well-being. While exposure to treatment and to supportive verbalizations from therapist to parents were not related to residualized change in well-being, these seem to be important factors in understanding the needs of parents with young children with ASD (e.g., parents with low well-being had higher attendance and received more supportive verbalizations). Taken together, the results suggest maternal well-being is an important and promising target for evidence-based behavioral parenting interventions such as IY-ASLD.
