Screening Protocol

17 september 2026 uppdaterad av: National Center for Complementary and Integrative Health (NCCIH)

Screening Evaluation of Volunteers for Studies of Pain

This study is a screening evaluation for volunteers who are interested in participating in National Center for Complementary and Integrative Health (NCCIH) research studies about pain and related processes, such as emotion, mood, and decision-making. Screening may include review of medical history, physical exam, vital signs, questionnaires, blood and urine tests, and optional sensory testing to better understand pain and related symptoms. The purpose is to identify and characterize healthy volunteers and people with pain who may be eligible for future NCCIH research studies. This screening study does not test a treatment and has no formal hypothesis.

Detaljerad beskrivning

Study Description:

This protocol will serve as a volunteer screening protocol for intramural NCCIH. It will provide a vehicle for recruiting, examination, and preliminary testing of research volunteers for NCCIH studies.

Objectives:

To provide a centralized and standardized service for recruiting, screening, and characterizing volunteers interested to participate in studies of pain and related processes (e.g., emotion, affect, decision-making). Depending on their screening characteristics participants will then be offered opportunities to participate in one or more of the current studies of pain and related processes.

Endpoints:

While records of demographics are kept, there is no planned endpoint.

Kohorter och interventioner

Grupp / Kohort
Healthy Volunteers Individuals screened under this protocol who are determined to be in good health and without a pain history that would classify them as a participant with pain. These participants may be considered for future NCCIH studies as healthy controls.
Participants With Pain Individuals screened under this protocol who have a current or prior pain history or pain symptoms identified through medical history, examination, questionnaires, or sensory testing. These participants may be considered for future NCCIH studies of pain and related processes.
