Although estimates concerning the prevalence of various forms of substance abuse vary considerably, it is critical to note that even the more conservative estimates indicate a major public health problem. Furthermore, increased drug experimentation has been frequently associated with the college experience. Utilizing a slightly modified version of the National Institute on Drug Abuse (NIDA) Monitoring the Future Survey, the present study examined the epidemiology of self-reported drug taking behaviors (e.g., alcohol, marijuana, tranquilizers, stimulants, psychedelics, etc.) among a sample (n = 683) of students attending a major public university. Data analyses focused on the specific settings and social groupings in which drug use occurred as well as on the frequency and type(s) of drug taking behaviors. Based on the results yielded from a disjoint cluster analysis, four distinct groups of drug users were identified. These four groups then served as categories of the dependent variable in a discriminant function analysis. A general linear models procedure was employed to identify the more efficacious discriminating (i.e., independent) variables. 相似文献

It is widely believed that monetary aggregates have failed to predict economic performance over 1983-87. This paper observes that the traditional definition of money (M1 lessother checkable deposits, or M1A) shows no evidence of structural change, and yields lower prediction errors for both real GNP and inflation over 1983-87Q2 than the errors obtained using M1 or M2. If there is a mystery, it is not why MIA has done so well, but why economists abandoned it for M1 or what was once called M1B (currency, demand deposits, and other checkable deposits). 相似文献

This study examined the effect of probing for additional information on the accuracy of deception detection. One hundred forty-eight experimental interactions were analyzed to see whether deceivers and truthtellers behave differently when probed and whether probing improved deception detection. Probing produced a number of changes in nonverbal behavior, several of which differed between deceivers and truthtellers. Probing may have communicated suspicion or uncertainty; therefore, deceptive sources were motivated to control their nonverbal demeanor to mask deception-related cues and appear truthful. Probing did not improve detection. Instead, probing receivers considered all sources more truthful. It is suggested that suspiciousness and prior knowledge may affect probing's efficacy. 相似文献

This article reviews the literature dealing with problems brought by student-athletes to college counseling and mental health centers. Among the issues discussed are fear of success; identity conflict; social isolation; poor athletic performance; academic problems; and career or vocational concerns. In addition, the authors examine the paradox that although athletes experience as much or more psychological distress as nonathletes, research indicates that athletes use professional services less often than nonathletes. Finally, the authors review approaches to psychological intervention, including short-term psychotherapy, very brief interventions, cognitive behavioral therapy, and career/vocational counseling, and discuss special considerations for conducting therapy with athletes. 相似文献
