Because studies examining youth drug use often have data with a high proportion of zeros, they often do not meet the assumptions for univariate or linear regression analyses that are typically used. We demonstrate the use of zero-inflated negative binomial regression models to address excessive zeros in drug use frequency on perceptions of…

Matching methods such as nearest neighbor propensity score matching are increasingly popular techniques for controlling confounding in nonexperimental studies. However, simple k:1 matching methods, which select k well-matched comparison individuals for each treated individual, are sometimes criticized for being overly restrictive and discarding…

The purpose of this study is to provide a profile of youths with hearing loss admitted to substance abuse treatment facilities. Intake data on 4,167 youths (28% female; 3% reporting a hearing loss) collected via the Global Appraisal of Individual Need-I assessment was used for the analyses. Information on demographics, environmental…

The purpose of this study was to develop and validate an observation measure designed to capture teachers' use of interactive teaching skills within the delivery of the All Stars substance use prevention program. Coders counted the number of times teachers praised and encouraged students, accepted and used students' ideas, asked questions,…

This article addresses two inconsistent findings in the literature on adolescent religious activity (RA) and substance use: whether a dose-response relationship characterizes the association of these variables, and whether the association varies by grade, gender, ethnicity, family structure, school type, and type of substance. Multinomial logistic…

Introduces structural modeling with nonnormal continuous variables, using the equations language of the micro-mainframe program EQS in the context of a longitudinal study of adolescent development that followed about 700 adolescents across an 8-year span into young adulthood. Two models are developed to assess the influence of drug use on…

Basic research and programs in substance abuse dealing directly with rural and small town populations lag far behind those aimed at urban groups, in both quality and quantity. A study was conducted to identify factors related to substance use by a preadolescent and early adolescent rural and small town population. Data were collected from 496…

It is important to examine the correlates of drug use and abuse among early adolescents to identify common patterns and factors of the beginning stages of drug abuse. The relationships between personal substance use, health beliefs, peer use, stated intention to use drugs in the future, sex, and religion were examined using data collected from 265…

Factors related to American Indian (AI) high school students' self-rated health were examined. Self rated health was measured as a single-item with a four-point response option ranging from poor to excellent health. Of the 574 participants, 19% reported "fair" or "poor" health, a percentage more than twice that for U.S. high school students in…

Two of the major topics treated in this report are the current prevalence of drug use among American high school seniors, and trends in use since 1975. Also reported are data on school grade of first use, trends in use at earlier grade levels, intensity of drug use, attitudes and beliefs among seniors concerning various types of drug use, and…

This article reviews current research on the long-term outcomes of children exposed to alcohol, cocaine, heroin, marijuana, and multiple drugs in utero. Differential intervention efforts based primarily on knowledge of a child's intrauterine exposure to drugs were unsupported by available evidence. The use of an ecological model for assessment and…

This paper discusses a study that examines the relationship between participation in religious youth groups, smoking behavior and subsequent use of cocaine, marijuana, and alcohol. The document briefly surveys earlier research on smoking and drug abuse. The study surveyed students, schools, parents, teachers, and student academic achievement data.…
