The purpose of this study was to develop and validate an ultra-short scale called the Quality of Life for Children with Autism Spectrum Disorder 3 (QOLASD-C3) from the full 16-item QOLASD-C scale. We first used network analysis to identify three core items to be retained on the QOLASD-C3 scale. Second, we used Cronbach's alpha and Pearson Product Moment correlations to determine the reliability and validity of the scale.

Objective: The aim of this study was to investigate the frequency and duration of technology use by autistic children, their primary activities when engaging with technology, and the association between technology use and quality of life. We assumed that technology serves as a means of communication with peers, and it is associated with an improved quality of life.

Methods: The study sample consisted of 61 parents of autistic children aged 5-10 years old.

Ecological validity refers to the meaningfulness or practical significance of research outcomes in everyday settings or the extent to which an intervention can be implemented by typical people during naturally occurring opportunities. In education, ecological validity may contribute to the adoption of interventions by teachers working with students in school settings. Our purpose in this review was to examine the evidence for ecological validity of functional communication training (FCT) used to address challenging behavior in school-age individuals with disabilities.

Many children with autism spectrum disorder (ASD) exhibit generalization errors following mand training. In this study, we extended the literature on the generalization of positively reinforced explicit mands in three young children with ASD and complex communication needs. First, we used mand training to teach a new, socially appropriate, positively reinforced explicit mand to request preferred toys.

Our purpose in this study was to provide additional psychometric evidence of the Quality of Life for Children with Autism Spectrum Disorder (QOLASD-C) scale. We used Rasch modeling to investigate the QOLASD-C functioning, the characteristics of the items comprising the scale, and the item functioning across subgroups of children with ASD based on gender and race/ethnicity. Results showed that QOLASD-C was unidimensional, met the local independence assumption, and measured quality of life (QOL).

Unlabelled: Our main purpose in this study was to investigate the levels of and the relationship between familiarity, confidence, training, and use of problem behavior interventions by special education teachers working with learners with autism spectrum disorder (ASD) in school settings. A total of 80 special education teachers in South Carolina and Virginia completed an online survey. Results indicate a positive correlation between teachers' familiarity, confidence, training, and use of problem behavior interventions.

Article Synopsis
  • The study aimed to assess the psychometric properties of the Quality of Life for Children with Autism Spectrum Disorder (QOLASD-C) scale, focusing on its factor structure and internal consistency.
  • The bifactor model demonstrated good fit and reliability, while demographic factors like age, race/ethnicity, and autism severity influenced overall quality of life scores, but gender showed no impact.
  • An optimal cut-off score of 37 for the QOLASD-C was identified, with implications for both research and practical applications in understanding children's quality of life.

Our purpose in this study was to examine the effects of an intervention package consisting of shared book reading and an adapted question-answer relationship (QAR) strategy comprised of visual supports and think-aloud scripts on listening comprehension in four preschool children with autism spectrum disorder (ASD). We used a single-subject concurrent multiple-baseline design across participants with continuous acquisition probes to evaluate the effects of the intervention package on producing acquisition and maintenance of listening comprehension across four types of comprehension questions. Visual analysis and Tau-U effect size indicated that the intervention package was effective in producing acquisition and maintenance of listening comprehension in preschool children with ASD.

Our purpose in this study was to validate the Quality of Life for Children with Autism Spectrum Disorder scale. We first conducted an exploratory factor analysis to examine the factor structure. Results suggested that a three-factor model (Interpersonal Relationships, Self-Determination, and Emotional Well-Being) should be retained.

Our main purpose in this review was to determine the extent to which ecological validity was demonstrated and assessed in single-case experimental design (SCED) studies examining the effectiveness of function-based interventions (FBIs) for children with autism spectrum disorder (ASD) within schools. We reviewed 55 SCED studies published between 1985 and 2019 to identify indicators of ecological validity and the instruments used to assess it. We also conducted an analysis to determine the extent to which implementation procedures were described.

Individuals with autism spectrum disorder (ASD) may engage in repetitive social-communication behaviors that can limit their skill acquisition, access to reinforcement, and access to less restrictive settings. Basic and applied research indicates that variability, or the extent to which responses are topographically different from one another, is influenced by antecedent and consequence interventions. Our purpose in this study is to systematically review the literature on interventions to increase variable social-communication behaviors in individuals with ASD.

In this study, we extended the literature on the generalization of negatively-reinforced mands in three young children with autism spectrum disorder (ASD). First, we used example and nonexample stimuli embedded in mand training to teach a new, socially appropriate, negatively-reinforced mand to reject unpreferred food items while continuously assessing mand discrimination. Second, we evaluated the discriminated generalization of the newly acquired mand by using untrained example and nonexample stimuli.

The development and the evolution of the Virginia Applied Behavior Analysis Consortium, a collaborative project between four institutions of higher education in the state of Virginia, are described. The main goal of the program is to address the shortage of certified behavior analysts by preparing special education teachers and autism specialists to implement effective behavior-analytic interventions in natural environments. In this article, we briefly discuss the history and the purpose of the program, its components, the evolution of the program, the advantages and outcomes of a collaborative model, and future directions for improvement.

In this study, we extended the literature on negatively-reinforced mands by teaching multiple novel, socially appropriate alternative mands to two young children with autism spectrum disorder (ASD). First, we replaced existing mands (e.g.
