Individual items scores were summed and dichotomized by median gBased on one question measured on 5-point Likert scale, and dichotomized by median hBoth internalized stigma scale and stigma consciousness scale are six items questionnaires measured on the 5-point Likert scale.
One question measured absolute physical activity (seldom, moderately, vigorously active) and one measured relative physical activity (more, about as, less active than peers).
Specifically, one question measured absolute PA (seldom, moderately, vigorously active) and the other measured relative PA (more, about as, less active than peers).
The survey comprised four questions measuring the expectation of competition, three questions measuring excitement level, three questions measuring purchase intention, and one question measuring current mood using a 7-point Likert scale ranging from "never" (1) to "very much" (7).
In this study, patient satisfaction was measured by a questionnaire with 13 questions, including one question measuring overall satisfaction (Table 1).
One question measured engagement with computer programs to visualize three-dimensional images of molecules (i.e., Cn3D), while the other queried about interest in analyzing biological information.
Our one-question measures can be considered as a strength for the study.
Thirdly, the study variables were assessed with one-question measures, which may explain why our levels of intrusive thoughts differed from those reported by others.
Based on the results of group discussion, the expert panel took the view that two or three questions were difficult for local patients to understand and so recommended just one question to measure regular source of care.
Both the Tinnitus Severity Scale and the Patient Global Impression Change (PGI-C) consist of only one question to measure the subjective perception of patients about their tinnitus severity at the time and the change of tinnitus complaints over time.
Similar to the self-rated health literature, one question was a "standard" measure and one was a "comparative" measure.
