PhenX - assessment of gallbladder disease and related conditions protocol 190201

Assessment gallbladder disease proto

Definition

This measure is used to assess whether the respondent has had symptoms as a result of gallstones or gallbladder problems and to determine whether the respondent received treatment for the gallbladder problem. The interviewer will provide the respondent with a show card containing a diagram of the upper body before asking the first question. Numbers that appear in parentheses after the answer choice are a skip pattern and direct the user to the next question in the series. These questions will not identify asymptomatic gallstones. For a more detailed assessment of gallbladder disease in adults, including identification of subjects with asymptomatic gallstones, see the National Health and Nutrition Examination Survey (NHANES) gallbladder ultrasound protocol in the Gastrointestinal Working Group Supplemental Information.
