OBJECTIVE To assess the impact of televised alcohol commercials on adolescents' alcohol use. METHODS Adolescents completed questionnaires about alcohol commercials and alcohol use in a prospective study. RESULTS A one standard deviation increase in viewing television programs containing alcohol commercials in seventh grade was associated with an excess(More)
Gamma-hydroxybutyric acid (GHB) is gaining popularity as a drug of abuse. Reports of toxicity and lethality associated with GHB use have increased. This survey study was designed to identify patterns of GHB use, its effects, and withdrawal syndrome. A survey inquiring about the effects of GHB was administered to 42 users. The results showed that GHB was(More)
Theories of cognitive processes and risk behavior have not usually addressed spontaneous forms of cognition that may co-occur with, or possibly influence, behavior. This study evaluated whether measures of spontaneous cognition independently predict HIV risk behavior tendencies. Whereas a trait-centered theory suggests that spontaneous cognitions are a(More)
HIV-associated neurocognitive impairment, particularly in the domain of prospective memory (ProM), increases the risk of poor everyday functioning outcomes, including medication non-adherence. However, whether ProM plays a role in health care compliance outside of the realm of medication adherence remains to be determined. This study evaluated the(More)
Although neurocognitive impairment is an established risk factor for medication nonadherence, standard neurocognitive tests developed for clinical purposes may not fully capture the complexities of non-adherence behavior or effectively inform theory-driven interventions. Prospective memory, an innovative cognitive construct describing one's ability to(More)
A Web-based coding application was designed to improve coding efficiency and to provide a systematic means of evaluating responses to open-ended assessments. The system was developed for use by multiple raters to assign open-ended responses to predetermined categories. The application provides a software environment for efficiently supervising the work of(More)
According to the multi-process theory of prospective memory (ProM), time-based tasks rely more heavily on strategic processes dependent on prefrontal systems than do event-based tasks. Given the prominent frontostriatal pathophysiology of HIV infection, one would expect HIV-infected individuals to demonstrate greater deficits in time-based versus(More)
The perceived positive and negative outcomes of alcohol use were studied in a sample of normal 8th and 10th grade students. Participants' responses provided associative frequency norms valuable for future research. Regression analyses showed (1) none of the individual-difference variables (alcohol use, exposure to vicarious sources of alcohol information,(More)
OBJECTIVES To evaluate a social network approach to develop an adolescent cohort for HIV vaccine preparedness and investigate characteristics that influence recruitment. METHODS We summarize baseline data from a prospective cohort study that included 4 sessions over 6 months. Fifty-nine HIV-infected adolescent and adult patients of a family-based HIV(More)
