Brief Summary:

Specific Aims Our study objective is to investigate if video peer modeling before the visit, plus immersive virtual reality during a preventive dental visit, reduces dental fear and uncooperative behaviors among children with ASD.

SPECIFIC AIM: To pilot and test the feasibility and effectiveness of video peer modeling and immersive virtual reality in reducing dental fear among children with autism undergoing preventive dental visits.

Methods: The investigators will enroll eighty (80) subjects aged 7-17 years with a known diagnosis of autism, who had a history of dental fear, per parental report.

Study hypotheses:

The primary hypotheses of interest are:

(i) The mean change in the Venham Anxiety Score (VAS) over the 4 month period in children with ASD who receive the video intervention (Group B) is different from the mean change in the VAS over the 4-month period in children with ASD in the control group.

(ii) The mean change in the VAS over the 4-month period in children with ASD who receive the immersive VR intervention (Group C) is different from the mean change in the VAS over the 4-month period in children with ASD in the control group.

(iii) The mean change in the VAS over the 4-month period in children with ASD who receive the video intervention plus the immersive VR intervention (Group D) is different from the mean change in the VAS over the 4-month period in children with ASD in the control group.

The secondary hypothesis is:

(i) The mean change in the Venham Behavior Score over the 4-month period in children with ASD in Group D is different from the mean change in the Venham Behavior Score over the 4-month period in children with ASD in Group B or C.

Arm Intervention/treatment
No Intervention: Control
Children assigned to Group A (control group) received usual care and therefore had no intervention before or during the return visit.
Experimental: Video peer modeling
Video peer modeling (at home, the child watched a DVD recording of a typically developing child undergoing a dental visit);
Behavioral: Video

Video peer modeling: The video demonstrates various stages of the dental visit experience. Children assigned to intervention Groups B or D reviewed the video at least once, but as many times as possible before the follow up visit.

Video goggles: This is a sunglass style video eyewear that contains two computer screens that can be used to watch 2 or 3D movies. Subjects randomized to Group C or D watched a 2D movie during the return visit, using the video goggles. Subjects who refused or were unable to wear the goggles watched the movie using a hand held portable DVD player.


Experimental: Video goggles or portable DVD only
Video goggles/DVD (during the dental visit, the child watched their favorite movie using sunglass style video eyewear, or portable DVD player);
Behavioral: Video

Video peer modeling: The video demonstrates various stages of the dental visit experience. Children assigned to intervention Groups B or D reviewed the video at least once, but as many times as possible before the follow up visit.

Video goggles: This is a sunglass style video eyewear that contains two computer screens that can be used to watch 2 or 3D movies. Subjects randomized to Group C or D watched a 2D movie during the return visit, using the video goggles. Subjects who refused or were unable to wear the goggles watched the movie using a hand held portable DVD player.


Experimental: Video peer modeling plus video goggles
Video peer modeling plus video goggles/DVD. At home, the child watched a DVD recording of a typically developing child undergoing a dental visit; During the dental visit, the child watched their favorite movie using sunglass style video eyewear, or portable DVD player.

Primary Outcome Measures :
  1. Anxiety [ Time Frame: 6 month ]

    Primary outcome:

    Anxiety: To assess the subject's level of anxiety, we will use the Venham Anxiety Rating Scale which assigns numerical values to the child's observable behaviors. It consists of 5 behaviorally defined categories that range from 0-5, and higher scores indicate greater levels of anxiety.(ref) The treating dentist and RA will use the Venham Scale to indicate their perception of level of anxiety experienced by the participant during the dental procedure.



Secondary Outcome Measures :
  1. Uncooperative behavior [ Time Frame: 6 month ]
    Behavior: To assess the subject's behavior during the dental visit, we will use the Venham Behavior Rating Scale.(ref) The Behavior Scale also consists of 5 behaviorally defined categories that range from 0-5, and higher scores indicate greater levels of uncooperative behavior.(ref) The Venham Anxiety and Behavior Rating Scales have been used extensively in behavior research to assess the level of anxiety and behavior of children in dental settings.(ref) The RA and treating dentist will rate te child's behavior once during the dental visit. The PI will train the dentist and RA on procedures to administer the Venham Anxiety and Behavior Rating Scale during the dental visit and will assess inter-rater reliability.


Other Outcome Measures:
  1. Pulse rate [ Time Frame: 6 months ]
    Physiological arousal: We will obtain the child's pulse rate as an objective measure of physiological arounsal during the dental procedure. The dental assistant will use a pulse oximeter to measure the pulse rate at three time points: - after the child is brought into the examination room, about 15 minutes into the dental procedure and about 5 minutes after the dental procedure is completed.

Criteria

Inclusion Criteria:

  • subjects aged 7-17 years with a known diagnosis of autism, who had a history of dental fear, per parental report.

Exclusion Criteria:

  • children with motor handicaps (e.g. cerebral palsy), and sensory, vision and hearing impairments (as these would have limited their ability to utilize intervention materials);
  • children with parents who did not speak English or Spanish; and
  • children who presented to clinic without their legal guardian.
