BACKGROUND Weight loss surgery (WLS) outcomes are poorly understood. This study aimed to evaluate the relationship of well-documented (e.g., health, diet, physical activity) and theoretically relevant variables (e.g., substance use and "food addiction") with both weight nadir and weight regain (WR) following WLS. METHODS A sample of 97 Roux-en-Y gastric(More)
Two studies were conducted to investigate the effectiveness of contingency management techniques in promoting punctual counseling attendance among methadone maintenance patients. In Study 1, 50 participants were recruited from an inner-city methadone maintenance program. Study 1 used an A-B-A design with baseline, intervention, and return-to-baseline(More)
In this 12-week double-blind placebo-controlled trial of methylphenidate (MTP) versus placebo in 48 cocaine-dependent attention-deficit/hyperactivity disorder (ADHD) adults, the authors sought to determine whether MTP would be safe, control ADHD symptoms, and affect cocaine use. Efficacy indexes revealed significantly greater ADHD symptom relief in the MTP(More)
To test the efficacy of sustained nicotine patch use among at-risk smokers, 55 smokers with a history of abstinence-induced depressed mood were randomly assigned to either Nicotine Maintenance or Standard Treatment following preliminary high-dose patch treatment. The Nicotine Maintenance group received 21 mg transdermal nicotine for 8 additional weeks; the(More)
To explore differences between women smokers and never-smokers in body image and eating patterns, we analyzed data obtained from 587 women (18-55 years old) recruited to participate in laboratory investigations not focused on weight concerns. The sample consisted of 420 current smokers and 167 never-smokers; 44% of each group were overweight or obese(More)
To investigate the issue of smoking initiation during college, we administered a survey of women's health behavior to college women during freshman orientation, at the end of their freshman year and again during their senior year. Never smokers (NS; n=374), early-onset smokers (EOS; n=52), and late-onset smokers (LOS; n=64) were compared on dieting(More)
Bariatric or weight loss surgery (WLS) patients are overrepresented in substance abuse treatment, constituting about 3% of admissions; about 2/3 of such patients deny problematic substance use prior to WLS. It is important to advance our understanding of the emergence of substance use disorders (SUDs) - particularly the New Onset variant - after WLS.(More)
This research examined two questions: (1) What is the prevalence of self-injurious behavior (SIB) among college students, overall and by gender, academic level, and sexual orientation? (2) To what extent is SIB associated with different forms of substance use and other risk behaviors? A probability sample of 5,689 students completed an Internet survey on(More)
The construct and convergent validity of the Substance Abuse Subtle Screening Instrument-Adolescent (SASSI-A) were examined in a population of suburban youth offenders. The analysis was conducted on archived data of 490 adolescent offenders from a suburban Circuit Court-Juvenile Division. Exploratory factor analysis results best supported a 5-factor(More)
WHAT IS ALREADY KNOWN ABOUT THIS SUBJECT Elevated rates of substance use disorders (SUDs), particularly (but not only) alcohol use, are observed among post-weight loss surgery (WLS) patients. The development of SUDs among post-WLS patients typically occurs 1-2 years post-surgery. Post-WLS patients are developing SUD at a much later time of life than is(More)
