Development of an Instrument That Monitors Behaviors Associated With OCD

To support the discovery of new means for revealing the presence of Obsessive Compulsive Disorder (OCD), facilitating detection through new technology-based metrics, and attempt to automate existing diagnostic procedures allowing for more efficient diagnostic methods that would broaden clinical scope and outreach.

Study Overview

• Status: Completed
• Conditions: OCD
• Intervention / Treatment: Other: No Intervention

Detailed Description

Aim 1: To observe and compare childhood behaviors regarding handwashing in OCD and control populations

Hypothesis 1: Control participants will spend less time washing their hands, will wash them less frequently, and will be less preoccupied with the sink when doing other activities.

Aim 2: To observe and compare childhood behaviors regarding organizing a cluttered area.

Hypothesis 2: OCD participants will be more disturbed by the presence of clutter and more compelled to organize the items than control participants

Aim 3: To observe and compare childhood behaviors regarding turning on/off light switches

Hypothesis 3: OCD children will be more likely to exhibit compulsive repetitive behaviors regarding the light switch than control participants

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Length of Handwashing	Researchers blindly rate the how long (secs) it takes participants to wash their hands.	Same Day
Behaviors Associated with Handwashing	Researchers blindly rate whether participants exhibit any unique behavior while washing their hands.	Same Day
Length of Free Arrangement	Researchers blindly rate how long it takes participants to freely organize a box of school supplies.	Same Day
Frequency of Movements During Free Arrangement	Researchers blindly rate how many times participants move an object while freely arranging a box of school supplies.	Same Day
Amount of Space Used During Free Arrangement	Researchers blindly rate how much space participants use while freely arranging a box of school supplies (small, medium, or large space).	Same Day
Length of Carpet Arrangement	Researchers blindly rate and compare how long (secs) it takes participants to arrange a box of school supplies on a plain versus patterned carpet.	Same Day
Frequency of Movements During Carpet Arrangement	Researchers blindly rate and compare how many times participants move an object while arranging a box of school supplies on a plain versus patterned carpet.	Same Day
Frequency of Adjustments During Carpet Arrangement	Researchers blindly rate and compare how many times participants adjust the positioning of an object while arranging a box of school supplies on a plain versus patterned carpet.	Same Day
Size of Arrangement According to Sample	Researchers blindly rate and compare how accurately participants replicate the size of the arrangement according to a sample picture (smaller than sample, approximate to sample, larger than sample) on a plain versus patterned carpet.	Same Day
Frequency of Checking the Sample	Researchers blindly rate and compare how many times participants check the sample picture of the arrangement while organizing a box of school supplies on a plain versus patterned carpet.	Same Day
