An Example of Probing Questions (This is the probing questions for the first screening question above.) |

Source: Design and Estimation of the 1985-94 National Health Interview Survey, Series 2, No. 110, National Center for Health Statistics, Hyattsville, MD, 1989. Note: In the NHIS, conditions are determined in two ways. First, participants receive one of six condition lists that ask them if they have a specific condition (see Table A-1). Second, participants are asked broad questions to reveal general health and functioning (the questions in the top panel of this table). If participants reveal they have health or functioning difficulties, they are then asked what conditions cause these difficulties (for example, the questions in the second panel of this table). This method misses those with conditions who have no such difficulties, while the first method captures those with conditions who have no health or functioning difficulties. So only one-sixth of the sample is directly asked about blindness. This one-sixth of the sample is a random sample, because being asked about blindness is not dependent on one's response to another question. The remaining five-sixths of the sample is choice-based, because revealing blindness is dependent on one's response (choice) to another question. |
