3. For a complete description of the NLSY79 and the entire NLS program, see Bureau of Labor Statistics, NLS Handbook 2000, Washington, DC.
4. The youngest members of the sample may have gotten questions about some risky behaviors in their later adolescent years. For example, the first alcohol questions appeared in 1982 when the respondents were 17-25 years old.
5. The measurement error introduced most likely increases the standard errors of any of our estimates, making it more difficult to detect significant relationships.
6. Note: The analysis sample excludes the military over-sample dropped after 1984 and supplemental economically disadvantaged non-black, non-Hispanic over-sample dropped after 1990.
7. The respondents were 29-32 at the time the outcome was measured.
8. DSM-III-R refers to the American Psychiatric Association's Diagnostic and Statistical Manual of Mental Disorders, Third Edition, Revised. This tool is used by practitioners to help diagnose and treat mental disorders. The manual was updated in 1994 with publication of DSM-IV.
9. The respondents were 28-32 at the time the outcome was measured.
10. This simplification seems reasonable given the scope of this study, however we clearly do not capture the full family context. For example, for an adolescent living with a single parent at age 14, we do not know whether the parents never married; whether a marriage ended in divorce or death, or whether a divorce (or death) occurred recently or earlier in the adolescent's life.
11. We require that the respondent must have lived with the biological parent at least one year.
