^c Response options were: Never = 1, Rarely = 2, Sometimes = 3, Most of the time = 4, and Always = 5
^d Suicide-related ideation or behavior (SRIB) identified on the GSHS was coded as present if there was an affirmative answer to one or more of the following questions as indicated by a “yes” response to the first two and any value > = 1 time in response to the third question:

2. During the past 12 months, did you ever make a plan about how you would attempt suicide?
3. During the past 12 months, how many times did you actually attempt suicide?
^e SRIB identified by the ZLDSI coded as present if there was any affirmative answer to the statement “During the past 15 days, how many times have you had thoughts that you would be better off dead, or of hurting yourself in some way?” An affirmative answer was indicated by positive responses to any one of the following: some days (1–5 days), more than a week (6–9 days), almost everyday (10–15 days)
