August 14, 2025 updated by: Wayne Goodman MD, Baylor College of Medicine

Measuring Automated Behavioral Observations & Vocal Expressions (ABOVE) While Recording From the Brain

The investigators propose to synchronize automated measurements of behavior - head, body, and face dynamics, gaze, and vocal prosody - with simultaneous recordings of brain activity in clinically relevant contexts.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Baylor College of Medicine (BCM), University of Pittsburgh (UPitt) and Brown University will collaborate on this research project. BCM will be the only site that will enroll study subjects and perform study assessments. UPitt and Brown will supervise data management, measurement and modeling of multimodal signals and collaborate on research design and machine learning.

Following initial screening, subjects will participate in one testing session lasting about 2 hours. The addition of these preliminary studies will allow investigators to obtain information in order to differentiate and code OCD-distress versus social anxiety and identify rituals related to OCD.

Research Material, Data, and Information to be collected:

Interviews, rating scales, video, audio, behavioral assessments, and heart rate will be obtained.

Preliminary Testing in Un-implanted Subjects: Automated Behavioral Measures of OCD-related Distress (i.e., obsessions and urge to ritualize) and Overt Rituals:

The Provocation OC task (Provoc) and the Trier Social Stress Test (TSST) will be used to evoke OC-related distress and anxiety unrelated to OCD (e.g., performance anxiety), respectively. These tasks will be preceded by a neutral baseline (the subject may be asked to describe how they traveled to the clinic to the experimenter) and a positive affect induction, the Broad-Minded Affective Coping procedure (BMAC) a clinical technique that uses recalled positive autobiographical memories and mental imagery to elicit positive affect. Because anxiety and negative affect may have carryover effects, neutral baseline and BMAC will be presented prior to the non-OCD and OCD distress inductions. In the BMAC, subjects will be instructed to recall and describe a recent positive memory/experience. The order of Provoc and TSST will be counterbalanced across the subjects. Use of a conveyor belt may be used during the Provoc tasks to present the evoking stimuli. Simultaneously recorded measures are noted in the Table attached in Section S and include: AFAR, new suite of behavioral measures (shown as shaded), hand/arm movements and heart rate.

A third provocation task will be added to elicit overt rituals (e.g., handwashing) in the clinic. It will occur following the BMAC and TSST/Provoc tasks and a relaxation break.

Subjects will be asked to wash their hands at a sink in our clinic inside an exam room where their behaviors will be recorded using hardware-synchronized cameras: one, to capture frontal view of the face for AFAR; and another, to record full body movement for CPM. The investigators are aware of only one prior study of automated coding of compulsive behavior. In that study, a computer vision approach was able to discriminate subjects with OCD from healthy subjects on the basis of handwashing videos in which regions of interest (ROIs) were defined for objects (e.g., soap dispenser) used for handwashing. The investigators will combine this ROI paradigm with a CPM approach that captures hand and body movements. Dropouts from the ritual paradigm will be replaced.

These same tasks will also be performed on up to 4 subjects that have consented to receive a DBS implant on a separate protocol. Informed consent will also be collected from these implanted subjects for the purpose of completing the tasks described above on this study.

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

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

17 years to 66 years (Adult, Older Adult)

Accepts Healthy Volunteers

Yes

Sampling Method

Non-Probability Sample

Study Population

The primary source of OCD subjects will be self-referrals generated through BCM Clinicaltrials website, Clinicaltrials.gov, and BCM Psychiatry Clinic. The investigators also anticipate referrals from local area clinicians in addition to affiliate entities.

Description

Inclusion Criteria:

OCD subjects:

  • The subject has a minimum score of ≥16 on the Y-BOCS;
  • If applicable, on a stable pharmacologic regimen;
  • Sample will be enriched with OCD subjects having contamination obsessions and handwashing compulsions, and scores on items 9 and 10 of the Y-BOCS reflecting difficulty resisting and controlling compulsions;

Healthy Control Subjects:

  • Men and women will be age/gender matched with subjects
  • Absence of any psychiatric disorder determined by the MINI^53 for DSM-5 with the exception of non-impairing specific phobia.
  • Low scores on measures of contamination concerns and disgust sensitivity based on Y-BOCS scores below 10 and the Disgust Scale-Revised (total score <8).

Exclusion Criteria:

OCD Subjects:

  • Subject has a documented lifetime diagnosis of psychotic disorders such as schizophrenia;
  • Alcohol or substance abuse/dependence reported within 6 months, excluding nicotine;
  • The subject is deemed at high risk of suicidal behavior or impulsivity. The Beck Depression Inventory^52 (BDI) will be completed by all subjects and responses reviewed by a clinician.

Healthy Control Subjects:

- Those not meeting the inclusion criteria described in the inclusion section above.
