Pictorial stimuli were presented in a Stroop task paradigm that enabled the recording of attentional bias. The sample comprised 33 pathological slot machine gamblers (PG) and 22 control participants. The design of the study had one between-subjects factor -Group (PGs vs control), and two within-subject factors: (1) Stimulus meaning (win-related gambling stimuli vs neutral stimuli) and (2) Exposure (subliminal vs supraliminal). The results supported the notion that the PG group had an attentional bias towards visual win-related gambling stimuli compared with the control group. Furthermore, the degree of attentional bias among the PG group was moderately negatively correlated with net loss in the week before testing. One possible treatment implication of the findings is to include in-vivo exposure sessions as a supplement to cognitive behavioural therapy for gambling. Future studies could also include non-win gambling-related stimuli and should also comprise non-pathological regular gamblers as an additional control group.
A total of 1351 high school students (52.3% males, 47.7% females) with mean age 17.5 years (SD = 2.2) from randomized school classes in Hordaland County, Norway, participated in an Internet survey conducted in 2004 about the lifetime use of anabolic steroids and personal acquaintance with at least one user of anabolic steroids. In addition to questions about anabolic steroids the participants completed the Hospital Anxiety and Depression Scale and the Alcohol Use Disorders Identification Test. They also answered questions about demography, smoking, and narcotic use. The lifetime prevalence for use of anabolic steroids was 3.6% for males and 0.6% for females. In all, 27.9% of the respondents reported having at least one acquaintance that used or had used anabolic steroids. Use of anabolic steroids and having acquaintances using such drugs were strongly related to use of other drugs such as alcohol, nicotine, and narcotics. Implications for prevention are discussed and the study's limitations are noted.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
