Alcohol use is associated with risks for HIV/AIDS. The association between alcohol and sexual risk may be accounted for by sensation seeking personality. However, sensation seeking in relation to substance use and HIV risk has not been examined in Africa. In this study, 292 men and 219 women receiving sexually transmitted infection (STI) diagnostic and treatment services in Cape Town, South Africa, completed anonymous behavioral surveys. Structural modeling was used to test a model of alcohol use and sensation seeking in relation to sexual risk behaviors. Results showed that sensation seeking and alcohol use in sexual contexts were related to HIV risks, controlling for gender and marital status. The association between sensation seeking and HIV risk was partly accounted for by alcohol use in proximity to sex. In contrast to studies conducted in the United States, sensation seeking was not related to alcohol-sex outcome expectancies. These findings suggest that alcohol use is an important HIV transmission risk factor for many STI clinic patients and that interventions for individuals who are characterized as sensation seekers are urgently needed in South Africa.

This study applied piecewise latent growth modeling to longitudinal survey data from 2 different samples of adolescents (N=1,002 and N=1,206) to examine the hypothesis that development of sensation seeking in middle school would predict development of substance use (cigarettes, alcohol, and marijuana) in middle school and high school. Results showed that sensation seeking had strong predictive value for both concurrent and distal marijuana and alcohol use in both samples; however, initial level of sensation seeking predicted initial level of cigarette use during high school in 1 sample only. White participants scored consistently higher on both initial level and rate of increase in sensation seeking than did participants of other ethnicities. Advantages of this methodology are discussed in the context of substance use research. (PsycINFO Database Record (c) 2010 APA, all rights reserved)  相似文献

Research has demonstrated the efficacy of brief motivational interventions (BMI) and alcohol expectancy challenge (AEC) in reducing alcohol use and/or problems among college students. However, little is known about variables that may qualify the effectiveness of these approaches. The present analyses tested the hypothesis that need for cognition (NFC), impulsivity/sensation seeking (IMPSS) and readiness to change (RTC) would moderate the effects of BMI and AEC. Participants (N = 335) were heavy drinking college students enrolled in a randomized 2 × 2 factorial study of BMI and AEC. Latent growth curve analyses indicated significant interactions for BMI × NFC and AEC × RTC on alcohol use but not problems. Simple slopes analyses were used to probe these relationships and revealed that higher levels of NFC at baseline were associated with a stronger BMI effect on drinking outcomes over time. Similarly, higher levels of baseline RTC were associated with stronger AEC effects on alcohol use. Future preventive interventions with this population may profit by considering individual differences and targeting approaches accordingly.

Examinations of gender differences in alcohol expectancies among college drinkers typically have used self-report measures to assess single expectancy dimensions and often have been confounded by drinking level. This study examined gender differences in alcohol expectancies using 2 assessment methods. College students (N = 88) completed self-report questionnaires, including expectancy likelihood and subjective evaluation endorsements of expectancies, and a computerized expectancy accessibility task. Expectancy accessibility and endorsement were modestly correlated, with higher alcohol consumption and female gender linked to greater accessibility and endorsement of social enhancement expectancies. Gender moderated the relation between consumption and sociability expectancy accessibility; among men, heavier drinking was associated with more rapid activation of expectancies. Findings suggest complexity in associations among these variables and underscore the need to capture the multidimensionality of the expectancy construct and its relationship to alcohol use.

This longitudinal study of 1,447 first-time college students tested separate time-varying covariate models of the relations between academic and social motives/behaviors and alcohol use and related problems from senior year of high school through the end of the second year in college. Structural equation models identified small but significant inverse relations between academic motives/behaviors and alcohol use across all time points, with relations of somewhat larger magnitude between academic motives/behaviors and alcohol-related problems across all semesters other than senior year in high school. At all time points, there were much larger positive relations between social motives/behaviors and alcohol use across all semesters, with smaller but significant relations between social motives/behaviors and alcohol-related problems. Multi-group models found considerable consistency in the relations between motives/behaviors and alcohol-related outcomes across gender, race/ethnicity, and family history of alcohol problems, although academic motives/behaviors played a stronger protective role for women, and social motives were a more robust risk factor for Caucasian and Latino students and individuals with a positive family history of alcohol problems. Implications for alcohol prevention efforts among college students are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)  相似文献

This study examined aldehyde dehydrogense (ALDH2) gene status, alcohol dehydrogense (ADH2) gene status, conduct disorder, and alcohol dependence in Chinese, Korean, and White American college students. Chinese had a lower rate of alcohol dependence (5%) than Koreans (13%) and Whites (17%). Koreans had a higher rate of conduct disorder (15%) than Whites (9%) and Chinese (6%). The relationship of ethnicity to alcohol dependence was mediated by ALDH2 status and conduct disorder, although Chinese ethnicity remained significant. ADH2 status was not related to alcohol dependence with ALDH2 included, and no interactions were significant. Results suggest that different rates of risk (e.g., conduct disorder) and protective (e.g., ALDH2 status) factors partially account for ethnic differences in rates of alcohol dependence.

Studies of Asian college students have found that rates of binge drinking are associated with variation in the aldehyde dehydrogenase (ALDH2) gene. Chinese and Koreans have different prevalence rates of the ALDH2?*?2 allele, alcohol use, and alcoholism. The association of ALDH2 status and ethnic group with binge drinking was examined in 328 Chinese, Korean, and White college students. Ethnic group differences were found, with Whites having the highest rate of binge drinking, followed by Koreans and then Chinese. Among Asian participants, ALDH2 status and ethnicity related to binge drinking in an additive manner. Possessing an ALDH2?*?2 allele and being Chinese were protective factors, and being White and being Korean without an ALDH2?*?2 allele were risk factors for binge drinking. These results suggest that ALDH2 status, as well as other factors that differ in Koreans and Chinese, but do not interact with ALDH2, are associated with binge drinking among Asians.

This study examined the impact of alcohol use and alcohol-related problems on several domains of life satisfaction (LS) in a sample of 353 college students. Alcohol use was associated with lower general satisfaction and anticipated future satisfaction among women. Female abstainers reported higher general and anticipated future satisfaction than did female heavy drinkers. Female students' alcohol use was unrelated to their academic, family, dating, or social satisfaction. Drinking among men showed a positive, curvilinear relation to social satisfaction but was unrelated to other domains of LS. Alcohol-related problems were associated with decreased LS among both men and women. These findings suggest that alcohol use by young adults is associated with both positive and negative outcomes that may be gender specific.

This study examined the relationship between personality traits implicated in the drinking literature (i.e., sensation seeking and anxiety) and reactivity to 2 different alcohol cues. The opportunity to consume alcohol was manipulated, and differences in urge and affective reactivity were assessed. Gray's (1987) model of impulsive sensation seeking and anxiety was adopted to investigate relationships between personality and responses to the appetitive (consumption) and aversive (no consumption, nonrewarding) alcohol cues in 40 regular social drinkers. The consumption cue produced increases in appetitive motivation and positive correlations with sensation-seeking traits. The no-consumption cue produced increases in aversive motivation and positive correlations with anxiety-related traits. It was concluded that Gray's model of impulsive sensation seeking and anxiety may provide a useful framework for examining the personality correlates of cue reactivity to different cues.

Most theoretical models of HIV risk behavior have not considered the role of personality factors, and few studies have examined mechanisms accounting for dispositional influences on sexual risk taking. This study elaborated on a conceptual model emphasizing sexual sensation seeking, alcohol expectancies, and drinking before sex as key predictors of HIV risk (S. C. Kalichman, L. Tannenbaum, & D. Nachimson, 1998). Multiple groups structural equation modeling was used to determine whether gender moderated relationships among these variables in a sample of 611 heterosexual, young adult drinkers (49% women, 76% Caucasian, mean age = 25 years). The model provided an excellent fit to the data, and gender differences were not substantiated. Sexual sensation seeking predicted HIV risk directly as well as indirectly via sex-related alcohol expectancies and drinking in sexual contexts. Findings suggest that expectancies and drinking before sex represent proximal mechanisms through which dispositional factors influence sexual risk outcomes. Moreover, these relationships appear to be similar in men and women. Interventions could benefit from targeting alcohol expectancies and drinking before sex in individuals with a dispositional tendency toward sexual risk taking.
