Validated questionnaires should not be modified.
T he reformatting and changes that were made to the Asthma Control Questionnaire (ACQ) [1] for the Post-cold Asthma Control and Exacerbation (PAX) study [2] raise some important concerns about modifying validated questionnaires.

Consequently, the quality of the questionnaires used in medical education research is hi...

متن کاملVirtual Testing with Validated Analysis Tools
Collier Research Corporation is working with Lockheed Martin Aeronautics (LM Aero) under United States Air Force Research Lab (AFRL) funding to develop a “certification-by-analysis” process to reduce unexpected failures during experimental testing that will, in turn, accelerate Air Force structural certification. The goal is early identification and avoidance of conceptual and preliminary desig...
متن کاملIntersections with Validated Error Bounds for Building Interval Solid Models
Interval arithmetic has been considered as a step forward to counter numerical robustness problem in geometric and solid modeling. The interval arithmetic boundary representation (Brep) scheme was developed to tackle this problem. In constructing an interval B-rep solid, robust and efficient computation of intersections between the bounding surfaces of the solid is a critical issue. To address ...
