Alcohol Consumption Moderates the Link Between Cannabis Use and Cannabis Dependence in an Internet Survey.

The link between cannabis use and cannabis dependence remains poorly understood. Some people use cannabis regularly without signs of dependence; others show dependence despite using less. This study examined alcohol consumption as a moderator of this association. A sample of 476 people (primarily Caucasian men) who used cannabis at least once per week reported their alcohol consumption, cannabis use, and cannabis dependence symptoms in an Internet survey. Regressions revealed significant interactions between measures of cannabis use and alcohol consumption when predicting cannabis dependence. Cannabis use covaried with cannabis dependence, particularly in people who consumed alcohol frequently or in large amounts per week. Despite limitations, these data suggest that alcohol may decrease the safety of cannabis consumption. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Alcohol, expectations, and sexual arousal in males: an information processing analysis

Using a balanced placebo drink administration procedure, 48 undergraduate male social drinkers were presented with erotic and nonerotic stimuli after completing the Mosher Forced-Choice Guilt Scale. Selective attention and recognition memory were measured in both visual and auditory modalities; penile tumescence was recorded continuously in reponse to auditory stimuli. The belief that alcohol had been consumed increased penile tumescence to both heterosexual and homosexual stimuli, but only in Ss high in sex guilt. Mild intoxication itself had no effect. Alcohol impaired memory for visual stimuli, while the belief that alcohol had been drunk facilitated memory for stimuli in the auditory modality. Correlational analysis did not support the hypothesis that alcohol expectation's impact on sexual responsiveness is mediated directly through its influence on selective attention and memory processes.

Drug and alcohol use by Canadian university athletes: a national survey

To gauge the extent of drug and alcohol use in Canadian university athletes, we estimated the proportion of Canadian university athletes using social and/or ergogenic drugs through survey methods. A secondary purpose was to examine athletes' perceptions of the value of drug testing and drug education programs. Using a stratified random sampling procedure, 754 student athletes were surveyed in eight different sports from eight universities across Canada. Results showed that 17.7 percent of athletes have used major pain medications over the past twelve months, 3 percent reported use of weight loss products, 0.9 percent reported anabolic steroid use, 16.6 percent reported use of smokeless tobacco products, 94.1 percent reported use of alcohol, 65.2 percent reported use of caffeine products, 0.7 percent reported use of amphetamines, 1.0 percent reported use of barbiturates, 19.8 percent reported use of marijuana or hashish, 5.9 percent reported use of psychedelics and 0.8 percent reported use of cocaine/crack.     

Drug and alcohol use in orthopedic trauma patients: a prospective study

Six groups of 16 rats each were fed a standard diet for 8 weeks. Aluminium (Al) complexed with organic anions (citrate, lactate, malate, or tartrate) was added to the diet of four of the groups and aluminium hydroxide to the diet of one group (control 'Al +'). Aluminium concentrations in the diets were 1500-2000 mg/kg. The sixth group (control 'Al -') served as control. Plasma, bone (femur), kidneys, cerebral cortex and cerebellum levels of aluminium were determined at 4 and 8 weeks. All the complexing agents increased tissue accumulations, compared with values in the two control groups, especially citrate in bone and kidneys and lactate in cerebral cortex. There were no significant differences (P < 0.05) in aluminium levels in the tissues considered between the 'Al +' and 'Al -' control groups. Our results show the ability of dietary organic acids to increase aluminium absorption and tissue accumulation and indicate that concurrent intake of aluminium and dietary organic acids is not appropriate.     

Alcohol outcome expectancies and alcohol use: A latent variable cross-lagged panel study.

The relation between alcohol outcome expectancies (EXP) and alcohol use was prospectively examined over 3 years in a mixed-gender sample of college students (N?=?465) at low and high risk for the development of alcoholism. Alcohol use remained fairly stable over 4 years, but EXP decreased significantly over the course of the study. Structural equation modeling techniques were used to examine reciprocal relations between EXP and alcohol use over 1- and 3-year intervals. Reciprocal prospective effects were demonstrated, but the nature of these effects appears dependent on the interval between measurement periods. Conceptually, these findings indicate both an etiologic role for EXP in predicting future alcohol use, and the influence of alcohol consumption on the development and maintenance of EXP. Methodologically, they point to the importance of the consideration of measurement interval in longitudinal research. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Underemployment and alcohol misuse in the National Longitudinal Survey of Youth

OBJECTIVE: This study measured the impact of unemployment and underemployment on alcohol misuse. METHOD: A panel of respondents from the National Longitudinal Survey of Youth was studied in 1984-85 and 1988-89. In each pair of years, the effect of employment change (e.g., becoming underemployed) on alcohol misuse was assessed controlling for misuse in the first year. Alcohol misuse was operationalized in two ways: elevated symptoms and heavy drinking. Three samples were analyzed: a core sample of 2,441 who were available in both pairs of years (approximately 65% male) and two extended samples that included everyone available in one pair of years but not the other (n = 4,183 in 1984-85 and n = 3,926 in 1988-89). RESULTS: The 1984-85 analyses revealed a significant association of adverse change in employment with both elevated alcohol symptoms and heavy drinking (the latter moderated by prior heavy drinking). The 1988-89 analyses found no relationship between adverse change in employment and heavy drinking in the core sample and no main effect of adverse change in employment on symptoms, but they did reveal interactions involving prior symptoms (core sample) and marital status (extended sample). CONCLUSIONS: Several explanations for these decreasing effects over time were considered including changes in measurement reliability, statistical power, economic environment and respondents' maturity. These results confirm previous findings that job loss can increase the risk of alcohol misuse, provide new evidence that two types of underemployment (involuntary part-time and poverty-level wage) can also increase this risk and suggest that these effects vary over time.     

Perceived vulnerability to alcohol-related harm in young adults: Independent effects of risky alcohol use and drinking motives.

Perceived vulnerability to negative outcomes can motivate heavy drinkers to adopt health protective behavior, but little is known about determinants of perceived vulnerability to alcohol-related harm. University students (N ?=?286) were assessed to determine epidemiological risk status on a standardized problem drinking measure, typical reasons for drinking and cutting down, and perceived risk of experiencing alcohol-related harm. Results showed a positive relationship between problem drinking status and perceived risk of experiencing harm. However, at-risk drinkers believed that they were less likely to personally experience harm than comparable peers (p ?     

Development of the OCDS-Revised: A Measure of Alcohol and Drug Urges With Outpatient Substance Abuse Clients.

Urges to use substances is an important construct in understanding the maintenance of substance use as well as relapse. There is a need to evaluate single instruments measuring global urges to use substances (including alcohol). The Obsessive Compulsive Drinking Scale (OCDS; R. F. Anton, D. H. Moak, & P. Latham, 1995) was revised and tested as a single measure of urges to use substances. Participants were 252 adults entering outpatient substance abuse treatment. Results suggest that the revised scale (OCDS-R) primarily assesses 1 global factor for urges to use substances. In addition, strong support was found for the reliability and concurrent validity of the OCDS-R, although results for its predictive validity were mixed. The OCDS-R is a brief, psychometrically sound self-report instrument that has applicability within clinical and research settings. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Employment and alcohol: analysis of a clinical casuistic

The relationship between alcohol and work was studied in a group of 537 voluntary patients (393 male and 144 female) admitted to the department of Medicina del Lavoro, Pavia University for alcohol rehabilitation. The highest incidence of alcohol abuse was found in non-working subjects (pensioners, unemployed, housewives) although the start of excessive drinking takes place after beginning a working activity; a cause-effect relationship between these two factors can not be clearly determined, however. It is true that the stress provoked by this new condition (introduction to the work experience) can, in certain subjects, be a contributing factor in alcohol abuse. The increasingly lower age of initiation to alcohol reconfirms the need for prevention and instruction even at scholastic level. We can deduce how no working condition, low age and low education can constitute makers of risk for alcohol abuse.     

Mechano-content analysis as an aid to predicting effects of advertising microcommunications.

Performed a regression analysis of 204 posters to predict the percentage of respondents who remembered seeing an outdoor advertising message. The independent variables were 21 mechanical and 6 content elements; the dependent variables were recognition scores. The predictive validity of 20 equations was too low to be of value to advertising communicators. The correlations between predicted and actual scores were low (.30-.41, p     

Review of Research Advances in Alcohol and Drug Problems.

Reviews the book, Research Advances in Alcohol and Drug Problems edited by Yedy Israel, Frederick B. Glaser, Harold Kalant, Robert E. Popham, Wolfgang Schmidt, and Reginald G. Smart (1981). This book is the sixth volume of the series, Research Advances in Alcohol and Drug Problems. The purpose of this series, as stated by the editors, is not to provide an annual review each year on a fixed selection of topics but rather "to present each year evaluative papers on topics in which enough recent progress has been made to alter the general scope in a particular area." In Volume 6 several chapters deal with highly specialized topics such as: Tolerance to sensitization to central stimulants, brain peptides, liver functions, and mutagenicity of alcohol and tobacco smoke. The prohibitive price $59.50 (U.S. dollars) and highly specialized and diverse nature of many of the chapters in this book, will likely prevent this book from finding its way into many personal libraries. This work would, however, be a worthwhile acquisition for any university or alcohol treatment library. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Treatment as harm reduction, defunding as harm maximization: the case of methadone maintenance

Despite numerous research studies demonstrating the efficacy of methadone maintenance treatment (MMT) in general and the value of retention in particular, the increasing defunding of this modality has compromised its potential. From 1990 to 1995 the lead author conducted a longitudinal research project to determine the impact of the cost of treatment on 233 San Francisco Bay Area study participants seeking, enrolled in, or defunded from MMT. This paper reports on selected findings from that study. Using variables of drug use, crime, gender and HIV risk, qualitative and quantitative results comparing those seeking treatment with those enrolled in treatment indicated that MMT functioned as a harm-reduction tool. When clients were defunded, however, drug use, crime and HIV risk increased and harm was maximized.     

Alcohol myopia and condom use: Can alcohol intoxication be associated with more prudent behavior?

We tested 2 competing theories about the effects of alcohol on intentions to engage in risky behavior. Disinhibition predicts that intoxicated people will exhibit risky behavior regardless of environmental cues, whereas alcohol myopia (C. M. Steele & R. A. Josephs, 1990) predicts that intoxicated people will be more or less likely to exhibit risky behavior, depending on the cues provided. In 4 studies, we found an interaction between intoxication and cue type. When impelling cues were present, intoxicated people reported greater intentions to have unprotected sex than did sober people. When subtle inhibiting cues were present, intoxicated and sober people reported equally cautious intentions (Studies 1-3). When strong inhibiting cues were present, intoxicated people reported more prudent intentions than did sober people (Study 4). We suggest that alcohol myopia provides a more comprehensive account of the effects of alcohol than does disinhibition. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Gambling, health and age: Data from the National Epidemiologic Survey on Alcohol and Related Conditions.

The health effects of recreational gambling are presently unclear, particularly across age groups. Theories of healthy aging suggest that social activities, including gambling, may be beneficial to the health of older adults. Using cross-sectional data from the National Epidemiologic Survey on Alcohol and Related Conditions (N=43,093), the authors examined associations between gambling (categorized as nongambling, recreational gambling, or problem/pathological gambling) and health and functioning measures stratified by age (40-64 years and ≥65). Problem/pathological gambling was uniformly associated with poorer health measures among both younger and older adults. Among younger respondents, poorer health measures were also found among recreational gamblers. However, among older respondents, recreational gambling was associated not only with some negative measures (e.g., obesity) but also with some positive measures (e.g., better physical and mental functioning). Longitudinal studies are needed to clarify the relationship between gambling and health in older adults in the context of healthy aging.

Development of an alcohol withdrawal clinical pathway: an interdisciplinary process

Studies show that as many as 40 percent of all patients in general hospitals are admitted because of complications related to alcoholism. However, the literature has little in specific clinical pathways, treatment protocols, or guidelines for the interdisciplinary care of these patients in the acute care setting. Furthermore, the little information that is published shows a lack of consistency in recommended treatment regimes. This article reviews a coordinated, interdisciplinary effort in developing and implementing a clinical pathway for alcohol withdrawal.     

Relapse Prevention for Alcohol and Drug Problems: That Was Zen, This Is Tao.

Relapse prevention, based on the cognitive-behavioral model of relapse, has become an adjunct to the treatment of numerous psychological problems, including (but not limited to) substance abuse, depression, sexual offending, and schizophrenia. This article provides an overview of the efficacy and effectiveness of relapse prevention in the treatment of addictive disorders, an update on recent empirical support for the elements of the cognitive-behavioral model of relapse, and a review of the criticisms of relapse prevention. In response to the criticisms, a reconceptualized cognitive-behavioral model of relapse that focuses on the dynamic interactions between multiple risk factors and situational determinants is proposed. Empirical support for this reconceptualization of relapse, the future of relapse prevention, and the limitations of the new model are discussed.

Back pain and agricultural work among farmers: an analysis of the Colorado Farm Family Health and Hazard Surveillance Survey

BACKGROUND: Back pain is the most prevalent occupational health problem experienced by much of the world's workforce. However, agricultural work-related back pain occurring among US farmers working on small operations or family farms is usually not included in surveillance. With data collected by Colorado Farm Family Health and Hazard Surveillance Survey, this study reports characteristics of and risk factors for back pain among adult farmers living in eight Colorado counties. METHODS: A stratified probability sample of 500 farms was selected in proportion to the number of farms in study areas. During the 4-year period from 1993 through 1996, 458 farms were enrolled in the study and 759 farmers were interviewed using a questionnaire. Information on self-reported back pain and potential risk factors among 742 white farmers was evaluated and reported here. RESULTS: A total of 194 farmers (26.2%) reported to have had at least one episode of back pain lasting for 1 week or more. Males had a slightly higher prevalence of back pain than females (28.6% vs. 22.5%) and the lower back was the predominantly affected part of body among both males and females. In 45.4% of males and 43.9% of females back pain was brought on by repeated activities. Males' activities at work were more likely to cause back pain while females' activities at home were more likely to cause back pain. Three factors were found to be significantly associated with back pain: being depressed (odds ratio (OR) = 3.68, 95% confidence interval (CI) = 2.23-6.09), farming/ranching as main activities (OR = 1.66, CI = 1.17-2.36), and worked in agriculture for 10 to 29 years (OR = 1.62, CI = 1.14-2.30). CONCLUSIONS: Our analyses indicate that back pain is an occupational health problem among farmers on small operations or family farms and that back pain affected males and females differently. The finding of significant positive associations between depression, farming activities, and back pain warrants further attention.
