PURPOSE To evaluate the reliability and validity of 11 PROMIS measures to assess symptoms and impacts identified as important by people with rheumatoid arthritis (RA). METHODS Consecutive patients (N = 177) in an observational study completed PROMIS computer adapted tests (CATs) and a short form (SF) assessing pain, fatigue, physical function, mood, sleep, and participation. We assessed test-...

The general medical services (GMS) contract Quality and Outcomes Framework (QOF) awards up to 70 points for measuring patient satisfaction with either the Improving Practices Questionnaire (IPQ) or the General Practice Assessment Questionnaire (GPAQ). The usefulness of data collected depends crucially on the validity and reliability of the measurement instrument. The literature was reviewed to ...

This article reports an initial validation of an instrument that measures basic interviewing skills and compares its psychometric results with another instrument that has been used more frequently to measure similar skills. Four field supervisors rated 30 students’ videotaped interviews (N=120) using two instruments, the validation, and a comparison instrument. The current validation instrument...

Evidence for the reliability and validity of two models of Ambulatory Monitoring, Inc. actigraphs was obtained by testing four instruments of each kind 10 times each on a precision pendulum. Correlation and coefficient of variation methods were used to analyze the data. Reliability coefficients of .98 were obtained for both models. Coefficient of variation methods yielded reliability coefficien...
