Novel Adaptive Cognitive Training in Autistic Adults with Co-occurring Insomnia

Not Applicable

Recruiting

• Conditions: Autism Spectrum Disorder; Insomnia
• Interventions: Behavioral: COGMUSE-AUT

• Registration Number: NCT06291298
• Lead Sponsor: University of South Florida

Brief Summary

The proposed study will test the usability and feasibility of a novel cognitive training (COGMUSE) for autistic adults with co-occurring insomnia (COGMUSE- AUT). Participants (n=15) will complete the cognitive training intervention for 60 minutes per day, 3 times per week for 6 weeks at home totaling to 18 hours. Weekly check-ins will be conducted by study staff over Teams to ensure adherence to the treatment and provide an opportunity for qualitative feedback on the game sessions played. During these 6 weeks, participants will fill out daily (2x/day) electronic sleep diaries and wear an actigraph device (GENEActiv). GENEActiv is a watch-like device that monitors light and movement activity.

Arm && Interventions

Group	Intervention	Description
COGMUSE-AUT	COGMUSE-AUT	Participants will complete the computerized cognitive training intervention for 60 minutes per day, 3 times per week for 6 weeks at home totaling to 18 hours.

Primary Outcome Measures

Name	Time	Method
Objective Cognition-National Institute of Health Toolbox	Up to 10 weeks	A computerized cognitive test battery measuring performance across several domains: executive function (Flanker inhibitory control task), Dimensional Card Sort Test (measures cognitive flexibility, accuracy score), working memory (List Sorting Task), verbal (episodic) memory (Auditory Verbal Learning Task) will be administered.

Secondary Outcome Measures

Name	Time	Method
Objective Slee-Daily Actigraphy	Up to 10 weeks	GENEActiv (Activiinsights), a watch-like device that monitors light and gross motor activity, will be worn 24 hours/7 days for 2 weeks at each assessment point.
Subjective Sleep- Electronic Daily Sleep Diaries	Up to 10 weeks	Online diaries completed each morning (\~5 mins) during 2-week assessment periods and 6 weeks training. Variables: sleep onset latency (time from lights-out until sleep onset), wake time after sleep onset, sleep efficiency (% time spent sleeping while in bed).
Insomnia Severity Index	Up to 10 weeks	5-item survey completed by adult with autism and parent/guardian if needed. Brief measure of current perception of insomnia symptom severity, distress and daytime impairment. Commonly used in insomnia treatment outcome research.
Sleep Habits Questionnaire	Up to 10 weeks	Modified Sleep Habits Questionnaire, based on child version and modified for adults. This questionnaire gauges sleep habits and possible difficulties with sleep.
Pre-Sleep Arousal	Up to 10 weeks	-Pre-sleep Arousal Scale is a 16-item self-report questionnaire comprising both cognitive and somatic manifestations of arousal. This questionnaire will be completed by autistic adult with assistance from parent/guardian as needed.
WHO Quality of Life-BREF	Up to 10 weeks	This measure assesses quality of life (QOL) within the context of an individual's culture, value systems, personal goals, standards and concerns.
Mood	Up to 10 weeks	State-Trait Anxiety Inventory: Inventory that asks respondents to rate how true 20 self-descriptive statements (e.g., I feel calm) are on a 4-point scale (1 = not at all, 4 = very much so). Typically, respondents are asked to rate statements according to how they generally feel (trait-anxiety scale) and how they feel in the current moment (state-anxiety scale). Total scores range from 20 to 80, with higher scores indicating greater maladjustment.
Depression	Up to 10 weeks	- Beck Depression Inventory (II): 21-item inventory that asks respondents to rate on a scale of 0 (no depressive feelings) to 3 (most depressive feelings) their feelings towards various aspects of daily living/situations. Higher total scores indicate worse depressive symptoms.
Game-related experience (completed during intervention)	Up to 10 weeks	Sessions played -- The graduate research assistant will check adherence through an online portal storing COGMUSESM data during weekly Teams check-ins with participant. Participants will also provide qualitative feedback on the game sessions played.; Weekly game -- Maximum test scores recorded.; Game Engagement Questionnaire - Completed at the end of intervention; Participants rate from 0 (none) to 4 (extremely) the degree to which they agree with 33 aspects of game experiences. Total score measures game engagement.
Adaptive Behavior Assessment System (ABAS-III)	Up to 10 weeks	Adaptive functioning --This assessment measures behaviors suitable for adults displayed in several domains such as communication, community use, functional academics, home living, health and safety, leisure, self-care, self-direction, social, and work. The assessment will be filled by the adult with autism with the help of the caregiver if necessary. Answers are provided in a likert scale with 0=is not able to do this behavior to 3= always (or almost always).
