Accurate descriptions of sex differences in the development of childhood conduct problems and adolescent delinquency will inform theories of their causes in fundamentally important ways. Using data on 4,572 offspring of a national sample of women, we tested descriptive hypotheses regarding sex differences. As predicted, the magnitude of sex differences varied with age, suggesting that multiple processes differentially influence levels of these behaviors in females and males across development. During childhood, boys scored lower on measures of cognitive ability and exhibited lower sociability and compliance and greater hyperactivity, oppositional behavior, and conduct problems. Most of these variables were associated with childhood conduct problems and adolescent delinquency equally in females and males, but maternal delinquency and early childhood sociability were correlated more strongly with childhood conduct problems in males and childhood compliance predicted adolescent delinquency more strongly in females. Both sexes exhibited both childhood-onset and adolescent-onset trajectories of delinquency. Although more males followed a childhood-onset trajectory, there were few sex differences in the early childhood risk correlates of either delinquency trajectory.

AAPOR SESSION E: Impact of Telephone Sampling Design on Sample Efficiency and Bias -- Friday 5/19/2000 1. Introduction. The National Longitudinal Survey of Youth (NLSY97) is the latest in a series of surveys sponsored by the U.S. Department of Labor (DoL) to examine issues surrounding youth entry into the work force and subsequent transitions in and out of the work force. The NLSY97 is following a cohort of approximately 9,000 youths who completed an interview in 1997 (the base year). These youths were between 12 and 16 years of age as of December 31, 1996, and are being interviewed annually using a mix of some core questions asked annually and varying subject modules. We will compare two different weighting strategies for the first three rounds of NLSY97 data.

In order to improve the precision of estimates for minority youths, the overall study design for NLSY97 included a large oversample of Hispanic youths and non-Hispanic black youths. The overall design resulted in one large screening sample of over 90,000 housing units to generate youth participants for NLSY97. These housing units were drawn from two independent area-probability samples: 1. a crosssectional (CX) sample designed to represent the various segments of the eligible population in their proper population proportions, and 2. a supplemental (SU) sample designed to produce, in the most statistically efficient way, the required oversamples of Hispanic youths and non-Hispanic black youths. This paper’s main concern is with the construction of sampling weights for estimating population characteristics using both samples together. The paper gives more detailed descriptions of the

Data are drawn from the National Longitudinal Survey of Youth (NLSY), which focuses on the labor market experiences of adolescents and has followed a representative sample of 12,686 youth ages 14 through 21 years for 23 years, from their adolescence into their early 40's. The NLSY includes a battery of questions about drug use that were administered during 5 years of the survey, in 1984, 1988, 1992, 1994, and 1998. Data were analyzed using logistic regression analysis and odds ratios. Results revealed that most respondents reported no drug use during the 5 years under examination. Marijuana use was reported by 42 percent of respondents, while 19 percent reported cocaine use and 3 percent reported crack cocaine use. Most respondents only reported use during one survey year or used the drug for only one more survey year. However, half of marijuana users who used in one survey year reported marijuana use in the next survey year. Approximately one-quarter of cocaine users reported cocaine use in the next survey year. In terms of predictors of heavy drug use as adults, results indicated that heavy marijuana use in adolescence was predictive of heavy cocaine use in adulthood. Results also showed that young male drug users were nearly twice as likely as young female drug users to become heavy adult drug users. Adolescents reporting significant amounts of illegal income were also twice as likely to become heavy cocaine users. The findings suggest that steering adolescents away from heavy marijuana use and criminal occupations may be an effective means of deterring future heavy drug use. Footnotes, exhibits, appendix.
