Computer questionnaire accurately measures psychological factors related to upper extremity disability
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.”
