African Americans experience significant disparities in treatment access, retention, and quality of care for alcohol and drug use (AOD) problems. Religious congregations, often the first point of contact for help with AOD problems, can play an integral role in improving access to treatment. However, little is known about the role of African America...

Homeless young adults are at risk for alcohol and other drug (AOD) use and risky sexual behavior. Interventions are needed to help these young people reduce their risky behavior, but this population is often difficult to engage and retain in services. We offered a four-session AOD and risky sex reduction program to 100 participants and examined if...

While propensity score weighting has been shown to reduce bias in treatment effect estimation when selection bias is present, it has also been shown that such weighting can perform poorly if the estimated propensity score weights are highly variable. Various approaches have been proposed which can reduce the variability of the weights and the risk...

Background: Neighborhood factors reported subjectively by residents and measured objectively at the census tract are both associated with adolescent alcohol, tobacco (cigarette and electronic cigarette), and other drug (marijuana) (ATOD) use. Less clear is how these neighborhood factors are longitudinally associated with each substance. Equivocal...

There is a widely held belief that children’s general and psychological health benefits from owning and/or interacting with pets. In our study, we aimed to determine whether children who live with a dog or cat in their home have better mental and physical health outcomes compared with children without such a pet. Our study design consisted of a sec...

Background: Systematic reviews of complex interventions can vary widely in purpose, data availability and heterogeneity, and stakeholder expectations. Rationale: This article addresses the uncertainty that systematic reviewers face in selecting methods for reviews of complex interventions. Specifically, it lays out parameters for systematic revi...

There is conflicting evidence about whether living with pets results in better mental and physical health outcomes, with the majority of the empirical research evidence being inconclusive due to methodological limitations. We briefly review the research evidence, including the hypothesized mechanisms through which pet ownership may influence health...

Hispanics, and particularly foreign-born Mexican Americans, have been shown to fare better across a range of health outcomes than might be expected given the generally higher levels of socioeconomic disadvantage in this population, a phenomena termed the "Hispanic Paradox". Previous research on social disparities in cognitive aging, however, has be...

Homeless young adults ages 18–25 exhibit high rates of alcohol and other drug (AOD) use, and sexual risk behaviors such as unprotected sex. Yet few programs exist for this population that are both effective and can be easily incorporated into settings serving this population. This pilot cluster cross-over randomized controlled trial evaluates AWARE...

It is often accepted as common knowledge that military personnel benefit from decompression time between a war zone and the home station. To capitalize on the potential benefits of a decompression period paired with support services, the U.S. Air Force established the Deployment Transition Center (DTC) at Ramstein Air Base in Germany in July 2010....

Background Driving under the influence (DUI) of alcohol is a major public health concern, and many individuals continue to drink and drive even after being convicted of a DUI offense. Latinos, in particular, are disproportionately likely to be arrested for a DUI, have higher rates of recidivism, and are more likely to die in alcohol-related acciden...

Peers have a major influence on youth during adolescence, and perceptions about peer alcohol use (perceived norms) are often associated with personal drinking behavior among youth. Most of the research on perceived norms among adolescents focuses on perceived descriptive norms only, or perceptions about peers' behavior, and correcting these percept...

Objectives: E-cigarettes (ECs) are increasingly popular among adolescents, who perceive them as "safer" than cigarettes. Although research has examined risk factors for adolescent EC use, little is known about how EC use correlates with health status and protective health behaviors.

Methods: Participants were 193 at-risk adolescents referred to a California diversion program called Te...

Clients who verbalize statements arguing for change (change talk [CT]) in psychotherapy are more likely to decrease alcohol and other drug use (AOD) compared with clients who voice statements in opposition of change (sustain talk [ST]). Little is known about how CT and ST are expressed in groups in which adolescents may vary in their AOD use severi...

Purpose Middle school students with a history of solitary substance use are at elevated risk for substance problems by young adulthood. Understanding how these students differ from social-only users on substance use behaviors and consequences, normative beliefs, social influences, and attitudes can inform efforts to reduce solitary use and its rela...

Objective: Little is known about what may distinguish effective and ineffective group interventions. Group motivational interviewing (MI) is a promising intervention for adolescent alcohol and other drug use; however, the mechanisms of change for group MI are unknown. One potential mechanism is change talk, which is client speech arguing for chang...

Background Among high-risk youth, those who may be at increased risk for adverse alcohol and other drug (AOD) use outcomes may benefit from targeted prevention efforts; how youth acquire AOD may provide an objective means of identifying youth at elevated risk. Methods We assessed how youth acquired alcohol and marijuana (purchasing vs. other means...

Objectives: This study assesses the independent and combined effects of (1) perceived peer norms, (2) best friend use, and (3) being in the presence of others who use on middle school adolescents' consumption of marijuana and alcohol, and how the effects of these sources of social influence evolve over time as youth progress through middle school....

The existing research aimed at understanding alcohol and drug (AOD) use patterns from early to late adolescence typically does not examine samples with substantial racial and ethnic diversity. This is a critical research gap because studies have suggested that non-white adolescents often have worse health outcomes compared to white adolescents, eve...

Objective This paper presents a new quasi-experimental approach to assessing place based policing to encourage the careful evaluation of policing programs, strategies, and operations for researchers to conduct retrospective evaluations of policing programs. Methods We use a synthetic control model to reduce the bias introduced by models using non-...
