Sleep and Central Auditory Processing Disorder in Autism Spectrum Disorder

Recruiting

• Conditions: Autism Spectrum Disorder; Sleep Disturbance; Central Auditory Processing Disorder

• Registration Number: NCT06059352
• Lead Sponsor: Loma Linda University

Brief Summary

The proposed study aims to understand poor sleep as a possible cause to CAPD in children and adolescents with ASD (ASD+) compared to ASD youth without CAPD (ASD-), using both caregiver-report and objective clinician administered measures. Additionally, the study will aim to understand the complex relationship between CAPD, sleep, and other associated phenotypic features of ASD such as executive and psychiatric functioning.

Detailed Description

Participation will involve one assessment session approximating 4 hours including administration of neurocognitive and socioemotional measures by trained research staff. The research team then will determine which participants meet CAPD diagnostic criteria for both the SCAN-3 and RGDT tests and assign them to the ASD+ group. Participants not meeting these criteria will be assigned to the ASD- group. Following the assessment visit, all participants will then be asked to wear actigraphy monitors (comparable to overnight polysomnography) regularly for 14 days during nighttime sleep to objectively measure sleep quality.

Primary Outcome Measures

Name	Time	Method
Sensory Processing Patterns in Children Ages 14 and Below	Through study completion, an average of one year	Sensory sensitivity is a composite measurement using the 86 item Sensory Profile 2 (SP-2). SP-2 has 4 quadrants; Seeking (degree child obtains sensory input); Avoiding (degree child is bothered by sensory input); Sensitivity ( degree child detects sensory input); Registration (degree child misses sensory input). SP-2 is completed by parents of subjects using a scale of 5 (almost always = 90% or more), 4 (frequently= 75% of the time), 3 (half of the time = 50%), 2 (occasionally= 25%), 1 (almost never = 10% or less), or does not apply.; Seeking quadrant normal limits are 20-47; elevated seeking scores are ≥ 48, reduced seeking behaviors are ≤ 19.; Avoiding quadrant normal limits are 21-46; elevated avoiding scores are ≥ 47; reduced avoiding scores are ≤ 20.; Sensitivity quadrant normal limits are 18- 42; elevated scores are ≥ 43; reduced scores are ≤ 17 and below. Registration quadrant normal limits are 19-43; elevated scores are ≥ 44; reduced scores are ≤18.
Sensory Processing Patterns in Children Ages 15 and Above	Through study completion, an average of one year	Sensory sensitivity is a composite measurement using the 60-item adolescent/ adult sensory profile (AASP). AASP has 4 quadrants: Low Registration, Sensation Seeking, Sensitivity; Avoiding. Subjects will respond using a scale of almost never (5% or less of the time), seldom (25% of the time), occasionally (50% of the time), frequently (75% of the time), and almost always (95% or more of the time).; Low Registration normal limits are 27-40; elevated scores are ≥ 41; reduced registration scores are ≤ 26.; Sensation seeking normal limits are 42-58; elevated sensation scores are ≥ 59; reduced sensation scores are ≤ 25.; Sensitivity normal limits are 26-40; elevated sensitivity scores are ≥ 41; reduced scores are ≤ 25.; Avoiding normal limits are 26-40; elevated scores are ≥ 41; reduced scores are ≤ 25.
