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…

The adolescent drug problem places a huge toll on society and a heavy burden on the criminal justice system. Research regarding the benefits of therapeutic community (TC) treatment for adolescents has shown it to be effective. Despite the ability of therapeutic communities to lower drug relapse and reduce criminality, a great deal remains unknown…

The leading substance of misuse among teens after tobacco, alcohol, and marijuana is the use of pain killers. Very few longitudinal studies on prediction of pain killer use have been conducted among teens. This study examined the 1-year prediction of self-reported last 30-day pain killer use controlling for baseline 30-day painkiller use among…

It is still under debate whether the reported effects of opioid maintenance therapy (OMT) on child behaviour are a direct effect of prenatal exposure, or whether other factors are involved. This prospective cohort study investigated three models: the teratogenic risk model, the maternal risk model, and a combined risk model in a group of 35…

This study tested the association between parent illicit drug use disorder (DUD) in early adulthood and observed parenting practices at ages 27-28 and examined the following 3 theoretically derived models explaining this link: (a) a disrupted parent adult functioning model,(b) a preexisting parent personality factor model, and (c) a disrupted…

The purpose of the present study was to examine whether peer involvement, family involvement, media within the school campus, and cultural beliefs about college life were related to student involvement in risky behaviors, such as binge drinking, illicit drug use, risky sexual behavior, and problem gambling. Bronfenbrenner's Ecological Model was…

Reexamined previous statistical comparisons of two models for adolescent drug abuse using new statistical estimation methods in causal modeling not requiring assumptions about normally distributed variables. An asymptotically distribution free method shows that the models fit even better than assumed in the initial work. (Author/JAC)

Investigated predictors of drug treatment retention of individual clients in terms of a contextual model. Found that the socioecological variables predicted the types of clients that entered treatment in terms of clinic level (aggregate) variables, and these predicted the corresponding individual level client variables and client outcomes.

An alternative social psychological model of moral development, proposed by Robert Hogan, is assessed. Five character-trait dimensions of moral character (moral knowledge, socialization, empathy, autonomy, and ethical attitudes) were used to predict a measure of rule-breaking behavior. Results indicate some support for Hogan's model. (Author)

Data are analyzed and discussed from a sample of Israeli secondary school students in an attempt to determine the social correlates of drug behavior. The probability of drug abuse is assessed in terms (1) of demographic and subgroup variables and (2) of specific social and behavioral traits. (RDN)

The focus of this study was to identify factors that differentiate women drug abusers who had experienced suicidal ideation from those who did not. Face-to-face interviews were conducted with 221 cocaine-using women in Atlanta, GA, 88 (39.8%) of whom reported thinking about committing suicide at least once during the 90 days prior to interview and…

Describes a study that tested a model that included individual and environmental indicators of bonding to predict smoking, substance use, and sexual activity among secondary students. Individuals reporting high levels of bonding were less likely to exhibit high-risk behavior, regardless of gender. School environment directly influenced ninth…
