Design Of WELL Being Monitoring Systems, Application in Autism (Do Well B)

July 25, 2016 updated by: University Hospital, Clermont-Ferrand
The worldwide prevalence of autism is constantly increasing. People with autisms have difficulties in communication and social interaction resulting from atypical perceptual and information processing, leading to the accumulation of anxiety. Extreme overloading experienced internally may not be visible externally. Identifying stressful situations at an early stage may avoid socially problematic behavior from occurring, such as self-injurious behavior. Activation of the autonomous nervous system (ANS) is involved in the response to anxiety, which can be measured through heart rate variability and skin conductance with the use of a portable device, non-intrusively and pain-free. Thus, developing innovative analysis of signal perception and reaction is necessary, mainly for the non-communicative individuals with autism.

Detailed Description

The protocol will take place in real life (home and social environments). We aim to associate modifications of ANS with external events which will all be recorded in a synchrony manner through a specific design (spy glasses with video/audio recording). Four phases will be carried out on autism participants and aged-marched controls: 1) 24-hour baseline pre-experiment (physical activity, sleep), 2) 2-hour in real life situation, 3) 30-minute in a quiet environment, interrupted by a few seconds stressful sound, 4) an interview to get comments and feelings about events that triggered anxiety. Autism and control participants will be together for phases 2 and 3, revealing different physiological responses to the same situations, and thus identifying potentially problematic events. We will apply the statistical analyses developed by our team on continuous ANS data. Detection of abrupt changes will allow segmenting the data in shorter time series of few minutes with a constant mean, and estimating their persistency or antipersistency through a piecewise constant fractal index. We will disentangle classes characterizing different behaviors such as anxiety, rest and physical activity.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Ages Eligible for Study

12 years to 25 years (Child, Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Clear autism spectrum disorder, based on the autism diagnostic interview - revised (ADI-R), the autism diagnostic observation schedule - generic (ADOS-G), and the Vineland adaptive behavior scales (VABS).

Exclusion Criteria:

  • change in medical prescription in the previous 3 months and during the experiment.

The same inclusion criteria will apply for the paired age and sex matched individuals with the exception of autism spectrum. The paired control will be chosen within the friends of individuals with autism. In case of difficulty to recruit controls, the psychologist referent may be served as control.
