Caregiver Strategies to Sensory Features for Children With Autism and Developmental Disabilities.

Background: Caregivers of children with autism spectrum disorders (ASD) and developmental disabilities (DD) implement myriad strategies to support their children during daily activities and routines, which are laden with sensory stimuli. Children's sensory features are often characterized by three patterns of response (i.e., hyperresponsiveness, hyporesponsiveness, sensory seeking), and little is known about how caregivers' strategies differ among these patterns. Therefore, we used a mixed methods analysis to examine the complex interplay between children's sensory response patterns, child characteristics (diagnosis, chronological age, mental age), and caregiver strategies. Specifically, we examined how children's sensory response pattern scores were associated with caregiver strategies within sensory response pattern and at the item level. Lastly, we described the differential strategies implemented by caregivers of children with ASD and DD by sensory response pattern. Materials and Methods: Participants included children with ASD (n = 77) and DD (n = 40) aged 2-10 years. Caregivers completed the Sensory Experiences Questionnaire-2.1. A convergent parallel mixed methods approach was used to analyze data. Results: Children's sensory response pattern scores were significantly, positively associated with caregiver strategies within each sensory pattern (hyperresponsiveness, hyporesponsiveness, seeking); however, child mental age, and chronological age were not significantly related to the rate of caregiver strategies across patterns. While caregivers of children with ASD reported using more strategies, child diagnosis did not moderate the association between child sensory response pattern scores and the rate of caregiver strategies used. Item analysis demonstrated specific child behaviors in response to sensory stimuli that elicited high rates of strategies among caregivers. Qualitative analysis revealed distinct themes characterized caregiver strategies within each sensory pattern for children with ASD and DD. Conclusion: Our findings demonstrated specificity of caregiver strategies to children's sensory response patterns in the context of families' everyday lives, which were not contingent on child diagnosis, mental age, or chronological age, thereby highlighting universal qualities of caregiving for young children who experience varying levels of sensory challenges. Targeted intervention approaches may differentially incorporate types of strategies based on sensory response patterns to more optimally facilitate children's activity participation.

Parent reflections of experiences of participating in a randomized controlled trial of a behavioral intervention for infants at risk of autism spectrum disorders.

BACKGROUND: Despite the mounting evidence of efficacy of early intervention for children with autism spectrum disorders, there is little research that considers the various perceptions and resources with which parents respond to the pressures and opportunities associated with participation in early intervention. Research is particularly lacking surrounding experiences of parents with infants who are at risk of autism spectrum disorders but do not (yet) have a diagnosed condition. OBJECTIVES: This qualitative study aimed to explore the experiences of caregivers following their participation in a randomized controlled trial of Adapted Responsive Teaching, a parent-infant relationship-focused intervention for infants at risk of autism spectrum disorders in a community sample. Parents were randomized into either the treatment group, in which they participated in the Adapted Responsive Teaching intervention, or the community services group, in which they were provided with information regarding local early intervention services and were encouraged, but not required to, seek community services as part of their inclusion in the randomized controlled trial. METHODS: Semistructured interviews were conducted with families following the completion of the randomized controlled trial. Participants consisted of 13 mothers and 4 fathers. Five dyads were interviewed together for a total of 14 families. Child ages ranged from 39 to 46 months at the time of interview. Analysis was conducted on 14 interviews from 10 families who were randomized into the treatment group and 4 families randomized into the community services group. Analysis was informed by a thematic analysis approach, which involved a systematic process of coding and theme identification both across and within groups. RESULTS: Themes that emerged across groups included Working against all odds, Value of the personal relationship, Getting the ball rolling, and Getting dad on board. One broad theme represented the data within the groups: Win-win (Adapted Responsive Teaching group) and Navigating amidst ambiguity (community services group). CONCLUSIONS: This study illuminates the personal experiences and contextual influences affecting families who are participating in the randomized controlled trial through early identification of "risk" status for autism spectrum disorders in their infants. Insights gained from these interviews may serve to refine and enhance intervention models and to enhance early intervention services for families.

Precursors and trajectories of sensory features: qualitative analysis of infant home videos.

OBJECTIVE. This study explored precursors and trajectories of extreme sensory patterns in children with autism spectrum disorders (ASD) compared with children with developmental delay (DD). METHOD. We conducted a retrospective analysis of home videos of 12 infants who later displayed extreme presence or absence of three sensory patterns at preschool and school age. RESULTS. In ASD, hyporesponsiveness was most evident in infancy, followed by sensory repetitions. Hyporesponsiveness appeared stable over time and also was a precursor of sensory seeking. Infants with DD had few sensory precursors. CONCLUSION. Precursors of extreme sensory features emerge early in children with ASD and appear relatively stable over time for a pattern of hyporesponsiveness but less stable for patterns of hyperresponsiveness and sensory seeking. These findings highlight the emergent nature of sensory features that may inform early identification and intervention.

Differential associations between sensory response patterns and language, social, and communication measures in children with autism or other developmental disabilities.

PURPOSE: To examine patterns of sensory responsiveness (i.e., hyperresponsiveness, hyporesponsiveness, and sensory seeking) as factors that may account for variability in social-communicative symptoms of autism and variability in language, social, and communication skill development in children with autism or other developmental disabilities (DDs). METHOD: Children with autistic disorder (AD; n = 72, mean age = 52.3 months) and other DDs (n = 44, mean age = 48.1 months) participated in a protocol measuring sensory response patterns; social-communicative symptoms of autism; and language, social, and communication skills. RESULTS: Hyporesponsiveness was positively associated with social-communicative symptom severity, with no significant group difference in the association. Hyperresponsiveness was not significantly associated with social-communicative symptom severity. A group difference emerged for sensory seeking and social-communicative symptom severity, with a positive association for the AD group only. For the 2 groups of children combined, hyporesponsiveness was negatively associated with language skills and social adaptive skills. Sensory seeking also was negatively associated with language skills. These associations did not differ between the 2 groups. CONCLUSIONS: Aberrant sensory processing may play an important role in the pathogenesis of autism and other DDs as well as in the rate of acquisition of language, social, and communication skills.

Psychometric validation of the Sensory Experiences Questionnaire.

INTRODUCTION: We evaluated the psychometric properties of the Sensory Experiences Questionnaire (Version 1; Baranek, David, Poe, Stone, & Watson 2006), a brief caregiver questionnaire for young children with autism and developmental delays used to identify sensory processing patterns in the context of daily activities. METHOD: Caregiver questionnaires (N=358) were analyzed to determine internal consistency. The test-retest subsample (n=24) completed two assessments within 2-4 wk. Internal consistency and test-retest reliability were analyzed using Cronbach's coefficient alpha and intraclass correlation coefficients, respectively. RESULTS: Internal consistency for the SEQ was alpha = .80. Test-retest reliability for the total score was excellent, with ICC = .92. DISCUSSION: The SEQ is an internally consistent and reliable caregiver report measure of young children's sensory processing patterns of hypo- and hyperresponsiveness. The SEQ can be used as an early tool for identifying sensory patterns in young children with autism and other developmental disabilities.
