The Long Term Impact of Adolescent Risky Behaviors and Family Environment. Other Explanatory Variables

08/01/2001

Sex: Individual respondent was assigned the value of "1" if he/she was identified as "male", otherwise the value of "0" was assigned.

Race and Ethnicity: The NLSY79 distinguishes among three mutually exclusive and exhaustive race-ethnicity groups. A respondent was designated as "non-black, non-Hispanic", "black", or "Hispanic" based on a racial/ethnic variable from the NLSY79 Screener File. Since Hispanic is a mutually exclusive group, this classification is different than used for Census Bureau tabulations where Hispanics can also be classified as "black" or "white."

Educational Achievement: Data have been collected during each NLSY79 survey on respondents' current school enrollment status, highest grade attended and highest grade completed. Information on highest grade completed from 1979 through 1998 was compiled to obtain a measure for the respondent's educational achievement. There are three categories for this measure: high school dropout, high school graduate, and some college and up.

Rosenberg Self-Esteem Scale: The Rosenberg Self-Esteem Scale administered during the 1980 interview was used to construct a summary score that measures the self-evaluation that an individual makes and customarily maintains. It describes a degree of approval or disapproval toward oneself (Rosenberg, 1965). The summary score ranges from 4 to 40, with higher scores designating higher self-esteem.
