For variables asad, anervous, ahopeless… and the other mental health indicators used to generate the K6 dperession indicator, there seems to be a response rate of about 68% (years 1999-2010), and 32% NIU. Was this because it was only asked 2/3 of the time? Also, I checked the variables and they are all the same missing across the variables.
For asad, anervous, ahopeless... why so many missing variables? Was this asked only 2/3 of the time?
Only sample adults were asked the mental health questions. A sample adult is the one adult (age 18+) per family who was selected at random to answer additional health-related questions, including the mental health questions. Thus, any person that does not have ASTATFLG=“1:Sample adult, has record” are coded as NIU for all of the mental health questions.
Hope this helps.
