Why do some variables in the CPES Suicidality section appear to be duplicates (e.g., V01995 and V02025, and V01999 and V02029)?

The Suicidality section has a skip at the very beginning (SD1). If the respondent was able to read, they were asked SD2-SD14, if not, they were asked SD15-SD27. Therefore, you need to combine the data from this series, e.g., combine V01995 and V02025, etc. Please also note that these questions were not asked of the entire NSAL sample (only African-American respondents were asked this in NSAL).
