Poling, Alan – Journal of Applied Behavior Analysis, 2010
Establishing appropriate relations between the basic and applied areas of behavior analysis has been of long and persistent interest to the author. In this article, the author illustrates that there is a direct relation between how hard an organism will work for access to an object or activity, as indexed by the largest ratio completed under a…

Rhodes, Scott D.; McCoy, Thomas P.; Hergenrather, Kenneth C.; Vissman, Aaron T.; Wolfson, Mark; Alonzo, Jorge; Bloom, Fred R.; Alegria-Ortega, Jose; Eng, Eugenia – Journal of Rural Health, 2012
Purpose: Little is known about the health status of rural immigrant Latino men who have sex with men (MSM). These MSM comprise a subpopulation that tends to remain "hidden" from both researchers and practitioners. This study was designed to estimate the prevalence of tobacco, alcohol, and drug use, and sexual risk behaviors of Latino MSM…

Pinkston, Jonathan W.; Branch, Marc N. – Journal of the Experimental Analysis of Behavior, 2010
The present experiment examined the effects of acute and daily cocaine on spontaneous behavior patterns of pigeons. After determining the acute effects of a range of doses, 9 pigeons were divided into three groups that received one of three doses of cocaine daily, either 1.0, 3.0, or 10.0 mg/kg cocaine. Measures were taken of spontaneous…

Fakier, Nuraan; Wild, Lauren G. – Journal of Adolescence, 2011
This study investigated the relationships among sleep problems, learning difficulties and substance use in adolescence. Previous research suggests that these variables share an association with executive functioning deficits, and are intertwined. The sample comprised 427 adolescents (M age = 16 years) attending remedial schools and 276 adolescents…

du Plessis, Karin; Corney, Tim – Youth Studies Australia, 2011
Prevalence rates and reasons for substance use were studied in a sample of 172 male construction industry apprentices who had a mean age of 20 years. Results were compared with those of men in similar age groups in Victoria, and regional and age differences were explored. Findings indicate that more metropolitan apprentices had experimented with…

Clark, Heddy Kovach; Shamblen, Stephen R.; Ringwalt, Chris L.; Hanley, Sean – Journal of Primary Prevention, 2012
We examined whether parental monitoring at baseline predicted subsequent substance use in a high-risk youth population. Students in 14 alternative high schools in Washington State completed self-report surveys at three time points over the course of 2 years. Primary analyses included 1,423 students aged 14-20 who lived with at least one parent or…

Landi, Nicole; Crowley, Michael J.; Wu, Jia; Bailey, Christopher A.; Mayes, Linda C. – Brain and Language, 2012
Concern for the impact of prenatal cocaine exposure (PCE) on human language development is based on observations of impaired performance on assessments of language skills in these children relative to non-exposed children. We investigated the effects of PCE on speech processing ability using event-related potentials (ERPs) among a sample of…

Schuetze, Pamela; Molnar, Danielle S.; Eiden, Rina D. – Journal of Applied Developmental Psychology, 2012
This study explored the possibility that specific, theoretically consistent profiles of reactivity could be identified in a sample of cocaine-exposed infants and whether these profiles were associated with a range of infant and/or maternal characteristics. Cluster analysis was used to identify distinct groups of infants based on physiological,…

Yoon, Jin Ho; Branch, Marc N. – Journal of the Experimental Analysis of Behavior, 2009
Under multiple schedules of reinforcement, previous research has generally observed tolerance to the rate-decreasing effects of cocaine that has been dependent on schedule-parameter size in the context of fixed-ratio (FR) schedules, but not under the context of fixed-interval (FI) schedules of reinforcement. The current experiment examined the…

Childs, Kristina; Dembo, Richard; Belenko, Steven; Wareham, Jennifer; Schmeidler, James – Journal of Child & Adolescent Substance Abuse, 2011
Variations in drug use have been found across individual-level factors and community characteristics, and by type of drug used. Relatively little research, however, has examined this variation among juvenile offenders. Based on a sample of 924 newly arrested juvenile offenders, two multilevel logistic regression models predicting marijuana test…

McKay, James R.; Van Horn, Deborah H. A.; Oslin, David W.; Lynch, Kevin G.; Ivey, Megan; Ward, Kathleen; Drapkin, Michelle L.; Becher, Julie R.; Coviello, Donna M. – Journal of Consulting and Clinical Psychology, 2010
Objective: The study tested whether adding up to 18 months of telephone continuing care, either as monitoring and feedback (TM) or longer contacts that included counseling (TMC), to intensive outpatient programs (IOPs) improved outcomes for alcohol-dependent patients. Method: Participants (N = 252) who completed 3 weeks of IOP were randomized to…

Purpose: In this study, the authors aimed to examine the long-term effects of prenatal cocaine exposure (PCE) on the language development of 12-year-old children using a prospective design, controlling for confounding prenatal drug exposure and environmental factors. Method: Children who were exposed to cocaine in utero (PCE; "n" = 183)…

Chaplin, Eddie; Gilvarry, Catherine; Tsakanikos, Elias – Research in Developmental Disabilities: A Multidisciplinary Journal, 2011
There is very limited evidence on the patterns of recreational substance use among adults with Intellectual Disabilities (ID) who have co-morbid mental health problems. In this study we collected clinical and socio-demographic information as well as data on substance use patterns for consecutive new referrals (N = 115) to specialist mental health…
