To measure differences in recall of categorical and metric information, four items included categorical options (for example, "A. Triassic…), and four included numeric magnitude response options (for example, "A. 230 million years ago…).
Each question is provided with various levels of agreement or categorical options for the patient to choose from.
It comprised 42 separate questions with categorical options available as answers (e.g. As an MP, has any person, male or female, ever physically attacked or tried to attack you? Options: YES or NO).
Studies providing self-reported data on total absence length, frequency and prevalence as pre-specified categorical options reported relatively high sensitivities (range 79-91% with workplace registers as reference standard) [ 5, 13, 17].
Perceived breast and ovarian cancer risk was assessed for each cancer with the survey question: "In your opinion, compared to other women your age, what are your chances of getting breast/ovarian cancer in your lifetime?"

This section was followed by a question which asked participants how much HIV-related pain they had experienced in the past month, with categorical options including none, a little bit, mild or infrequent, moderate, severe or persistent and don't know.
All items use categorical response options (range: 2 6 options).
Dendrograms were generated by using the categorical character option and the unweighted pair group method of averages (UPGMA) clustering method.
Dendrograms were generated by using the categorical character option and the UPGMA (for unweighted pair-group method with arithmetic averages) clustering method.
Visual presentation of survey questions with categorical response options may allow greater time for processing initial options leading to primacy effects in those inclined to satisfice.
