The Mokken scale analysis is a method of item response theory (IRT), which is based on the following assumptions: unidimensionality, local independency and monotonicity.
Until this area is investigated more fully no recommendations can be made on including incentives in health care research as a method of improving response.
We investigated two complementary methods that characterize the occurrence of RS: factor analysis, comprising Principal Component Analysis (PCA) and Multiple Correspondence Analysis (MCA), and a method of Item Response Theory (IRT).
Object tracking is a powerful method of response collection.
In the absence of an optimal method of response assessment, we adopted a pragmatic approach to measure response by clinical, radiological and pathological criteria to evaluate whether ER, PgR, HER-2 status or Ki-67 proliferation index before or after treatment predict response to anthracycline-based PST in women with primary breast cancer.
Using PET as an early method of response assessment, this non-invasive technique seems to offer the chance for in-vivo chemosensitivity testing during treatment.
Moreover, telephone administration can be particularly valuable in injury research as it provides an alternative method of response to those who cannot write or type due to injury.
18F-fluorodeoxyglucose positron emission tomography (FDG-PET) can provide estimates of parameters related to the delivery, retention, and metabolism of glucose, and therefore has been proposed as a method of characterizing the response of tumors to treatment [1 4].
The analysis is applied to the analysis of the 'picture-frame' experiment, and it is shown that this experiment provides a method of measuring the response functions.
