Psychological Treatment of Disability-Related Pain: Efficacy and Mechanisms

Individuals from the study's recruitment sources with the diagnoses listed above will be contacted by research staff via telephone and invited to be screened for participation. In addition, individuals interested in participating may contact research staff upon learning about the study through a description listed on an approved website or a referral. Research staff will use a recruitment script for purposes of screening subjects and explaining the study. In addition, the initial screening process will also include conducting a cognitive screening known as the 6-item cognitive screener.

Research staff will verify the diagnoses (MS, SCI, AMP, MD or LBP) of prospective subjects who have not been 'pre-verified' in one of three ways during the recruitment process:

1. Research staff will attempt to determine whether a subject from has a University of Washington Medical Center (UWMC)/Harborview Medical Center (HMC) medical record by conducting a simple search using a secure application.

If research staff are unable to locate a medical record for the prospective subject from recruitment strategy #1, or if the individual is part of recruitment strategy #4 (i.e. if individual sees description of study on clinicaltrials.gov and contacts research staff), then one of two options will be pursued: 2. Subjects will be asked during the initial screening process if staff may review their medical records if they have received services at the UWMC/HMC since their diagnosis; 3. Subjects will be asked during the initial screening process if staff may contact a physician of their choice to verify their diagnosis if (a) they have not received services at the UWMC/HMC since their diagnosis; (b) they refuse to give staff permission to review their UWMC/HMC medical records; or (c) staff for some reason cannot find a UWMC/HMC medical record despite the subject attesting to being a patient at one time at the UWMC/HMC and giving staff permission to review his/her records.

Only individuals whose diagnosis has been verified (either via medical record review prior to/during screening or through verification via the subject's physician depending on recruitment source) will proceed with the psychological screening assessment.
