Researchers of this study found the Patient Reported Outcomes Measurement Information System computer adaptive testing questionnaire showed results comparable to paper-based pain self-efficacy questionnaires for patients with upper extremity disability.

“We conclude that the Pain Interference [computerized adaptive testing] CAT and the Depression CAT are two valid questionnaires for evaluating psychological factors in patients with hand and upper-extremity illness,” Mariano E. Menendez, BS, and colleagues wrote in their study. “The widespread adoption of [Patient Reported Outcomes Measurement Information System] PROMIS-based CATs can potentially lead to a reduction in not only respondent and researcher burden, but also in sample size requirements and ultimately study costs.”

Menendez and colleagues asked 213 patients to complete a web-based version of the QuickDASH questionnaire, a pain self-efficacy questionnaire, and two PROMIS-based CAT questionnaires for pain interference and depression, according to the abstract. The researchers used a multivariate analysis to compare the psychological answers in the PROMIS-based CAT questionnaires to the QuickDASH questionnaire.

They found a large correlation between the pain interference PROMIS-based CAT questionnaire and QuickDASH and the pain self-efficacy questionnaire as well as QuickDASH and the pain self-efficacy questionnaire, according to the abstract. The depression PROMIS-based CAT questionnaire had a medium correlation with QuickDASH and with the pain interference PROMIS-based CAT questionnaire. Menendez and colleagues noted, “[T]he best multivariable model for QuickDASH included the Pain interference computerized adaptive testing, prior treatment received, and smoking, and accounted for 57% of the variability.”
