The manual will be available to clinicians after feasibility and pilot testing.

Neurophysiological Correlates of Sensory-Based Phenotypes in ASD.

Children with autism spectrum disorder frequently present with atypical behavioral responses to sensory stimuli, as well as differences in autonomic nervous system (ANS) and neuroendocrine activity. However, no one consistent pattern appears to explain these differences within this heterogeneous population. To conceptualize more homogenous ASD subgroups, sensory-based subtypes have been explored. One subtyping mechanism groups children by sensory responsivity pattern in addition to sensory domain. Differences in nervous system responsivity to sensory input within this sensory-based subtyping scheme have not yet been investigated. This exploratory study used ANS indices (respiratory sinus arrhythmia [RSA], skin conductance level) and neuroendocrine (salivary cortisol) response to examine patterns differentiating these subtypes. Significant differences in RSA were found during baseline, and during tactile, tone and movement stimuli (p < 0.05). Subtype membership was predicted by RSA changes during auditory stimulation and recovery periods (p < 0.05). Results confirm that children with an adaptive sensory responsivity subtype differ from those children with sensory processing dysfunction, however, physiological variables did not distinguish between children with different patterns of sensory processing dysfunction.

Evaluation in Ayres Sensory Integration® (EASI) Tactile Perception Tests: Construct Validity and Internal Reliability.

IMPORTANCE: Assessment of tactile perception is foundational for addressing aspects of occupational performance. OBJECTIVE: To evaluate the construct validity and internal reliability of four new tactile perception tests. DESIGN: Causal comparative groups design. SETTINGS: Homes, schools, and therapy practices across the United States. PARTICIPANTS: Children ages 3 to 12 yr: typically developing (n = 174) and those with sensory integration concerns (n = 153). OUTCOMES AND MEASURES: Rasch analyses to evaluate construct validity; analysis of covariance to evaluate group differences. RESULTS: The Rasch model confirmed evidence of construct validity for each of the four tests. The typically developing group scored significantly higher than the clinical group on all tests (η2p = .040-.105, p < .001). Person reliability indices and strata indicated moderate to strong internal reliability (Rasch person reliability indices = .69-.87; strata = 2.33-3.82). CONCLUSIONS AND RELEVANCE: The Evaluation in Ayres Sensory Integration® (EASI) Tactile Perception Tests are reliable and valid measures for assessing tactile perception in children ages 3 to 12 yr. Findings suggest that these tests are likely to be clinically useful and appropriate for children in this age range and may provide critical information regarding underlying sensory functions necessary for optimal occupational performance. What This Article Adds: This article provides data supporting the reliability and validity of the EASI Tactile Perception Tests in a U.S. SAMPLE: These assessments can be used by therapists trained in their administration to assess tactile functions that may affect participation in activities, tasks, and occupations.

IMPORTANCE: Assessment of praxis using valid and reliable measures is important for understanding factors affecting occupational participation. OBJECTIVE: To evaluate evidence of construct validity and internal reliability of data gathered with four newly developed praxis tests. DESIGN: Comparative descriptive design. SETTING: Homes, schools, and therapy practices across the United States. PARTICIPANTS: A control group consisting of 163 children without any concerns or diagnoses and a case group of 145 children with sensory integration difficulties, ages 3 to 12 yr. OUTCOMES AND MEASURES: Rasch analyses to evaluate construct validity, and Student's t tests to evaluate group differences. RESULTS: Total test scores and most item scores conformed to Rasch model expectations. Group differences were significant; the control group scored higher. Internal reliability was strong. CONCLUSIONS AND RELEVANCE: Findings support the validity and internal reliability of the four praxis tests. What This Article Adds: This study adds to the growing body of evidence for validity and reliability of the Evaluation in Ayres Sensory Integration® tests.

Evaluation of MealSense©: A Sensory Integration-Based Feeding Support Program for Parents.

IMPORTANCE: Children with autism spectrum disorder (ASD) often experience feeding challenges related to difficulties with sensory integration. OBJECTIVE: To evaluate the content, acceptability, and usefulness of MealSense©, an online parent education program for children with ASD who have feeding challenges related to poor sensory integration. DESIGN: A descriptive study in which experts reviewed and rated MealSense content for consistency with Ayres Sensory Integration® (ASI) principles and evidence-based practices in feeding. PARTICIPANTS: A convenience sample of expert reviewers (n = 5) and parents of children with ASD and feeding challenges (n = 5). RESULTS: Expert ratings (n = 5) met criteria showing that MealSense is consistent with ASI and evidence-based practices in feeding. Parent ratings (n = 5) met criteria showing that MealSense is acceptable and useful. CONCLUSIONS AND RELEVANCE: MealSense is acceptable and useful to parents of children with ASD and is consistent with ASI and evidence-based practices in feeding. What This Article Adds: This study provides preliminary support for MealSense as an evidence-based tool to supplement direct intervention for children with ASD and feeding difficulties. Further research is needed to determine its efficacy in improving the transfer of feeding skills into the home environment.

Occupational Therapy Using Ayres Sensory Integration®: A Randomized Controlled Trial in Brazil.

IMPORTANCE: Research conducted in the United States has found that occupational therapy using Ayres Sensory Integration® is an effective evidence-based intervention for children with autism spectrum disorder (ASD). Replication of this research in other cultures is needed. OBJECTIVE: To evaluate the outcomes of occupational therapy using Ayres Sensory Integration in a sample of Brazilian children with ASD. DESIGN: Prospective randomized controlled trial. SETTING: Occupational therapy clinic. PARTICIPANTS: Seventeen children with ASD ages 5-8 yr (n = 9 in the intervention group, n = 8 in the usual-care control group) recruited from a local hospital via flyers and word-of-mouth. Completed pretreatment characterization and baseline measurement. INTERVENTIONS: The intervention group received occupational therapy using Ayres Sensory Integration, and the control group received usual therapeutic and educational services only. OUTCOMES AND MEASURES: We conducted a pre-post assessment of self-care and socialization using the Pediatric Evaluation of Disability Inventory and individualized goal ratings. RESULTS: Participants in the intervention group scored significantly higher on outcome measures of self-care (p = .046, rb = .57), social function (p = .036, rb = .61), and parent-identified goal attainment (p < .001, rb = .94) compared with the control group. CONCLUSIONS AND RELEVANCE: Occupational therapy using Ayres Sensory Integration was effective in enhancing self-care, socialization, and goal attainment for children with ASD in a Brazilian cohort. What This Article Adds: This study contributes further support from outside the United States that occupational therapy using Ayres Sensory Integration is an effective evidence-based intervention to improve self-care, socialization, and parent-identified goal attainment in children with ASD.

However, guidelines for this parent component have not been published. OBJECTIVE: To obtain input from stakeholders on a revised guidebook for parent education during ASI intervention. DESIGN: Cross-sectional survey design. SETTING: Online surveys. PARTICIPANTS: Experts in ASI, occupational therapy practitioners who use this approach, and parents of children with autism who received occupational therapy using this intervention. OUTCOMES AND MEASURES: Surveys designed and vetted to obtain input on content and usability. RESULTS: Experts rated the guidebook as consistent with ASI principles, practitioners rated it as clinically useful, and parents rated it as useful and clear. CONCLUSIONS AND RELEVANCE: The parent guidebook for ASI is ready for further testing and use. What This Article Adds: This report adds knowledge translation and best practice strategies in parent education to the parent guidebook for ASI and provides evidence that it is acceptable by experts, parents, and clinicians.

EASI Praxis Tests: Age Trends and Internal Consistency.

IMPORTANCE: Ayres Sensory Integration® is an evidence-based practice that requires a comprehensive assessment before intervention. The Evaluation in Ayres Sensory Integration (EASI) is intended for this purpose, and psychometric data are needed to determine its validity and reliability. OBJECTIVE: To evaluate the internal consistency of four EASI Praxis tests and their validity as developmental measures. DESIGN: Cross-sectional developmental design. SETTING: Participants' homes. PARTICIPANTS: Typically developing children and young adolescents, ages 6 to 12 yr (N = 234). Outcomes and Measures: We analyzed four EASI Praxis tests using Cronbach's α, Pearson correlation coefficients, and one-way analysis of variance to explore internal consistency and developmental trends. RESULTS: The findings indicate moderate to high internal consistency for all tests. Significant correlations between age and praxis scores indicate that the EASI Praxis tests are sensitive to developmental changes. CONCLUSIONS AND RELEVANCE: Occupational therapists can have confidence in the internal consistency and sensitivity to developmental changes of these praxis scores through early adolescence. What This Article Adds: Occupational therapists administering EASI Praxis tests can have confidence that they consistently measure praxis ability and are sensitive to developmental changes across ages 6 to 12 yr. The results suggest that praxis continues to develop into early adolescence, and adolescents may benefit from assessment and intervention targeting praxis ability.

Choosing Performance-Based Outcome Measures of Daily Living Skills and Socialization for Clinical Trials in Autistic Children.

IMPORTANCE: Robust and psychometrically sound performance-based outcome measures are needed for clinical trials of occupational therapy interventions for children with autism. OBJECTIVE: To demonstrate a systematic approach for choosing psychometrically sound performance-based outcome measures of daily living skills and socialization for use in clinical trials of occupational therapy interventions for children with autism. DESIGN: Rapid literature review to identify appropriate measures for studies with this population followed by quality indicator ratings and a nominal group process. SETTING: University. PARTICIPANTS: Four experts in autism and pediatric outcome measurement. Outcomes and Measures: Twenty-one outcome measures of daily living skills and socialization were identified and reviewed. RESULTS: Seven measures met the inclusion criteria. The Assessment of Motor and Process Skills and the Evaluation of Social Interaction-Second Edition, received the highest ratings and group consensus. Several other measures were also scored highly. CONCLUSIONS AND RELEVANCE: Careful assessment of psychometric properties is an important component of choosing outcome measures for a clinical trial, but burden of assessment and study objectives are important considerations. What This Article Adds: This project demonstrates use of a systematic process for choosing outcome measures for a planned clinical trial.

Evaluation in Ayres Sensory Integration® (EASI) Vestibular and Proprioceptive Tests: Construct Validity and Internal Reliability.

IMPORTANCE: Vestibular and proprioceptive functions play a critical role in occupational performance and participation. Assessment of these functions in a reliable and valid manner is part of a comprehensive assessment in the Ayres Sensory Integration® frame of reference, commonly applied in pediatric occupational therapy. OBJECTIVE: To report on reliability and validity of six tests of vestibular and proprioceptive functions of the Evaluation in Ayres Sensory Integration (EASI). DESIGN: We used Rasch analyses to examine and modify the number of items and scoring categories on the six tests and known-groups analysis to examine group differences. We evaluated internal consistency using Cronbach's α and Rasch person reliability. PARTICIPANTS: The sample contained typically developing children (n = 150) and children with sensory integration concerns (n = 84); all participated voluntarily. Outcomes and Measures: The EASI is used to measure sensory and motor functions in children ages 3 to 12 yr. The six tests of vestibular and proprioceptive functions were analyzed in this study. RESULTS: Data from >96% of items conformed to the expectations of the model. We found statistically significant group differences (ps < .001-.128; ds = 0.20-1.31), with the typically developing children group scoring significantly higher on all but one test, and moderate to strong evidence of internal consistency (Rasch person-reliability indices ≥ 0.80; strata > 3) for five of six tests. CONCLUSIONS AND RELEVANCE: The EASI vestibular and proprioceptive tests have strong construct validity and internal reliability, indicating that they are psychometrically sound clinical measures. What This Article Adds: The development of occupational therapy assessments with strong psychometric properties, such as the EASI tests of vestibular and proprioceptive functions, enhances clinical practice and research by elucidating the factors affecting participation in accurate and dependable ways so that occupational therapy interventions can be focused and effective.

Cultural Adaptation of the Evaluation in Ayres Sensory Integration® (EASI) for Spanish-Speaking Populations.

IMPORTANCE: Spanish-speaking populations represent a significant percentage of occupational therapy clientele globally. Culturally appropriate Spanish translations of assessments are therefore imperative. This study describes the process of a culturally adapted translation of a set of tests for use with Spanish-speaking pediatric populations. OBJECTIVE: To produce a culturally adapted Spanish translation of the Evaluation in Ayres Sensory Integration® (EASI) for international use. METHOD: We used cultural adaptation methodology that included direct and back translations of the EASI by bilingual translators and interviews with pediatric occupational therapists and children ages 3-6 yr from Spain. Linguistic experts helped revise the translations, and pediatric occupational therapy leaders in five Spanish-speaking North and South American countries reviewed the translations for comprehensibility and cultural appropriateness. RESULTS: Back translations demonstrated equivalence with the original EASI tests except for a few test instructions and scoring criteria. Interviews with occupational therapists and children in Spain revealed some comprehension difficulties for several tests, which were revised in consultation with a linguistic expert. Additional adaptations were made on the basis of recommendations to address cultural differences by occupational therapy leaders from five North and South American countries. Most changes in wording were made in one EASI test (Praxis: Following Directions) that is heavily dependent on language comprehension. CONCLUSIONS AND RELEVANCE: We used currently recommended methodologies to develop and adapt a Spanish translation of the EASI for use across diverse cultures. What This Article Adds: A Spanish translation of the EASI has been developed for use in culturally diverse Spanish-speaking countries around the world.

Occupational Therapy Interventions for Children and Youth With Challenges in Sensory Integration and Sensory Processing: A Clinic-Based Practice Case Example.

Evidence Connection articles provide case examples of how practice decisions may be informed by findings of systematic reviews sponsored by the American Occupational Therapy Association (AOTA) Evidence-Based Practice (EBP) Project. This Evidence Connection article describes a case report of a child with a diagnosis of autism spectrum disorder who has difficulties in function and participation related to challenges in sensory integration. This article is the first in a two-part series, and it focuses on occupational therapy provided to the child by a clinic-based therapist in collaboration with the child's school-based occupational therapist. Part 2 in this series will describe the same child's intervention by the school-based therapist. Intervention decisions are informed by findings of systematic reviews of intervention effectiveness that were part of an AOTA EBP Project addressing occupational therapy interventions for children and youth with challenges in sensory integration and sensory processing.

Occupational Therapy Interventions for Children and Youth With Challenges in Sensory Integration and Sensory Processing: A School-Based Practice Case Example.

This Evidence Connection article is the second article in a two-part series. The first article described a case report of occupational therapy provided to a child with a diagnosis of autism spectrum disorder and challenges in sensory integration in a clinic setting (Parham et al., 2019). This article describes the same child's occupational therapy service delivery by the occupational therapist working in the school setting.

Efficacy of Occupational Therapy Using Ayres Sensory Integration®: A Systematic Review.

This systematic review addresses the question "What is the efficacy of occupational therapy using Ayres Sensory Integration® (ASI) to support functioning and participation as defined by the International Classification of Functioning, Disability and Health for persons with challenges in processing and integrating sensory information that interfere with everyday life participation?" Three randomized controlled trials, 1 retroactive analysis, and 1 single-subject ABA design published from 2007 to 2015, all of which happened to study children with autism, met inclusion criteria. The evidence is strong that ASI intervention demonstrates positive outcomes for improving individually generated goals of functioning and participation as measured by Goal Attainment Scaling for children with autism. Moderate evidence supported improvements in impairment-level outcomes of improvement in autistic behaviors and skills-based outcomes of reduction in caregiver assistance with self-care activities. Child outcomes in play, sensory-motor, and language skills and reduced caregiver assistance with social skills had emerging but insufficient evidence.

Introduction to the Evaluation in Ayres Sensory Integration® (EASI).

Comprehensive, reliable, and valid assessment is essential for individually tailored, appropriate, and effective intervention planning and implementation. Research, education, and practice using an Ayres Sensory Integration® (ASI) approach have a long history of prioritizing comprehensive assessment. To meet the need for a set of tests that will fully evaluate the constructs of ASI with psychometrically strong, internationally appropriate, and easily accessible measurement tools, the development of the Evaluation in Ayres Sensory Integration® (EASI) has been initiated. This article introduces the EASI, describes the overarching plan for its development, and reports the results of promising preliminary analyses of discriminative validity data.

Sleep in Children with Autism Spectrum Disorder.

The purposes of this paper are to provide an overview of the state of the science of sleep in children with autism spectrum disorder (ASD), present hypotheses for the high prevalence of insomnia in children with ASD, and present a practice pathway for promoting optimal sleep. Approximately two thirds of children with ASD have chronic insomnia, and to date, the strongest evidence on promoting sleep is for sleep education, environmental changes, behavioral interventions, and exogenous melatonin. The Sleep Committee of the Autism Treatment Network (ATN) developed a practice pathway, based on expert consensus, to capture best practices for screening, identification, and treatment for sleep problems in ASD in 2012. An exemplar case is presented to integrate key constructs of the practice pathway and address arousal and sensory dysregulation in a child with ASD and anxiety disorder. This paper concludes with next steps for dissemination of the practice pathway and future directions for research of sleep problems in ASD.

Application of Data-Driven Decision Making Using Ayres Sensory Integration(®) With a Child With Autism.

Health care and educational legislation and policy require that clinicians demonstrate, using measurement and report of outcomes, accountability for services rendered. Clinical algorithms have been developed and are used by various health care professionals to assist with hypothesis generation and systematic clinical reasoning; however, they do not explicitly guide measurement of outcomes as part of the reasoning process. Schaaf and colleagues developed the Data-Driven Decision Making (DDDM) process to address the greater need for outcome measurement, systematically support decision making, target intervention more precisely, and measure and document outcomes. This article describes the application of the DDDM process with a child with ASD who received occupational therapy using Ayres Sensory Integration(®).

Creating Evidence for Practice Using Data-Driven Decision Making.

To realize the American Occupational Therapy Association's Centennial Vision, occupational therapy practitioners must embrace practices that are not only evidence based but also systematic, theoretically grounded, and driven by data related to outcomes. This article presents a framework, the Data-Driven Decision Making (DDDM) process, to guide clinicians' occupational therapy practice using systematic clinical reasoning with a focus on data. Examples are provided of DDDM in pediatrics and adult rehabilitation to guide practitioners in using data-driven practices to create evidence for occupational therapy.

State of the Science: A Roadmap for Research in Sensory Integration.

This article builds on the work of Case-Smith and colleagues and proposes a roadmap to guide future research in occupational therapy. To foster best practice in the application of principles and practices of sensory integration (SI), the pillars of practice, advocacy, and education are identified as elements that provide the foundation for research. Each pillar ensures that SI research is conducted in a rigorous and relevant manner. To this end, achievements to date are discussed, with proposed goals presented for each pillar. Finally, the roadmap builds on the pillars and outlines implications for occupational therapy with the overarching theme that a wide array of scientists, educators, therapists, and service recipients will be needed to ensure that those who may benefit most have access to intervention that is evidence based, theory driven, and provided within the highest standards of service delivery.

Measuring change in somatosensation across the lifespan.

OBJECTIVE: The study aim was to determine natural variability in somatosensation across age groups using brief measures. We validated measures in a community-dwelling population as part of the National Institutes of Health (NIH) Toolbox for Assessment of Neurological and Behavioral Function (NIH Toolbox; http://www.nihtoolbox.org). METHOD: Participants included community-dwelling children and adults (N=367, ages 3-85 yr) across seven sites. We tested haptic recognition, touch detection-discrimination, and proprioception using brief affordable measures as required by the NIH Toolbox. RESULTS: Accuracy improved from young children to young adults; from young to older adults, the pattern reversed slightly. We found significant differences between adults and older adults. One proprioception test (kinesthesia; p=.003) showed gender differences (females more accurate). We provide expected score ranges for age groups as a basis for understanding age-related expectations for somatosensory perception. CONCLUSION: The age-related patterns of somatosensory perception from this study refine decision making about performance.
