Abstract Objective: This study extends the college heavy episodic drinking literature by examining the associations between features of psychopathy and antisocial personality disorder (ASPD), on the one hand, and heavy episodic drinking and associated problem behaviors, on the other. Participants: Participants were 159 (85 male, 74 female) undergraduates from a private university. Methods: Participants completed self-report measures assessing alcohol use, frequency, and consequences of heavy episodic drinking, and personality pathology. Results: It was found that psychopathy, independent of ASPD, was related to the prediction of heavy episodic drinking frequency and problems associated with alcohol use. It was also found that the relation between traits of psychopathy and heavy episodic drinking are limited largely to the impulsive and antisocial aspects of this condition. Conclusion: These findings point to the need for further investigation of the association between psychopathy and ASPD traits and heavy episodic drinking behaviors in college students. 相似文献

Abstract Objective: To determine if the substance use patterns of one's close friends and romantic partners would be a significant contributor to the co-occurrence of borderline personality disorder (BPD) features and drug use problems above and beyond impulsivity and negative emotionality. Participants: Participants were 2,202 undergraduates who attended a large southeastern university between 2003 and 2006. Methods: All subjects completed measures assessing the presence of BPD symptoms, drug use problems, general personality traits, and the proportion of their friends and partners who had used illicit drugs within the past 12 months. Results: The illicit drug use patterns of one's friends and romantic partners was a significant contributor to the co-occurrence of BPD features and drug use problems even when controlling for levels of impulsivity and negative emotionality. Conclusions: These findings suggest possible additional avenues for treatment focusing on helping students with BPD and drug use problems modify their social group. 相似文献

Abstract Objective: To examine cigarette smoking among young adults based on education status. Participants: Community-based sample of 2,694 young adults in the United States Methods: The authors compared 3 groups—those not in college with no college degree, 2-year college students/graduates, 4-year college students/graduates—on various smoking measures: ever smoked, smoked in past month, smoked in past week, consider self a smoker, began smoking before age 15, smoked over 100 cigarettes in lifetime, ever tried to quit, and plan to quit in next year. Results: The authors found that for nearly all the smoking measures, the 4-year college group was at lowest risk, the noncollege group was at highest risk, and the 2-year college group represented a midpoint. Differences between groups remain after adjusting for parents’ education and other potential confounding factors. Conclusions: Smoking behaviors clearly differ between the 2-year, 4-year, and no college groups. Interventions should be tailored for each group. 相似文献

Abstract Objective: To evaluate the psychometric properties of a new self-report questionnaire designed to assess college students’ intentions to employ 31 specific alcohol-reduction strategies. Method: Students attending a large public university were recruited to complete alcohol-reduction, drinking history, and personality questionnaires online. Results: Based on item–total correlations and principal components analysis, the authors eliminated 3 items and calculated average intention ratings across the remaining 28 items. The resulting scale had appropriate unidimensionality and excellent internal consistency. Correlations of intention questionnaire scores with measures of drinking history, alcohol outcome expectancies, sensation seeking, and impression management provided some support for criterion and discriminant validity of the questionnaire. Conclusion: This questionnaire could be employed as an outcome measure to evaluate prevention programs and as a clinical tool to identify clients who have little intention to employ drinking reduction strategies in heavy drinking situations. 相似文献

Abstract Objective: This literature review provides an analysis of the current state of the empirical research on sexual health among students attending historically black colleges and universities (HBCUs). Methods: Several electronic databases were used to identify 24 empirical studies that met criteria for inclusion in this review. Results: The results indicated that perceived human immunodeficiency virus (HIV) risk, religiosity, HIV testing, condom use, and substance use were as high or higher for black HBCU students in comparison with students of other racial/ethnic groups. Comment: Consistent with past findings, sexually transmitted infections continue to be of concern among HBCU students, as seen in the general black population. Limitations: This review only examined cross-sectional studies published between 2000 and 2013. Conclusions: The findings in this review suggest the importance of moving beyond individual risk models to examining structural barriers and assets related to promoting sexual health on HBCU campuses. 相似文献

Abstract Objective: To examine the relationship between mindfulness and alcohol problems in college students, as well as the role of stress as a mediator in this relationship. Participants: Participants were 310 students from a small, private college in the Northeast. Methods: Students completed self-report measures, including the Perceived Stress Scale, the Five Facet Mindfulness Questionnaire, and the Rutgers Alcohol Problems Index. Results: Mindfulness was negatively correlated with alcohol problems and stress, whereas stress positively correlated with alcohol problems. Results implicated stress as fully mediating the relationship between mindfulness and alcohol problems. Alcohol problems were negatively correlated with the Acting With Awareness and Describing Experience facets of mindfulness. Conclusion: Mindfulness-based stress reduction or other mindfulness programs may be useful in decreasing alcohol problems on college campuses via the effects on stress. 相似文献

Abstract Objective: This study examined how communication with parents is related to college students’ body satisfaction. Participants and Methods: Participants (N = 134; 58 males and 76 females) completed a survey in March 2011 assessing body satisfaction and perceptions of communication with mothers and fathers. Results: Daughters’ body satisfaction was negatively correlated with perceptions of problematic communication with mothers and fathers. Sons’ body satisfaction was positively correlated with open communication with their mothers and negatively correlated with problematic communication with their mothers. Conclusions: Findings indicated problematic communication with mothers was the most powerful predictor of daughters’ body satisfaction, whereas open communication with mothers was the best predictor of sons’ body satisfaction. 相似文献

Abstract Objective: The authors examined trait hope and hopelessness as potential moderators of the association between depressive symptoms and suicidal behavior. Participants: A diverse sample of 372 college students. Methods: Depressive symptoms, hopelessness (Beck Hopelessness Scale), trait hope (Trait Hope Scale), and suicidal behaviors were assessed. Trait hope is defined as confidence in the ability to identify and attain goals, whereas hopelessness encompasses future attitudes and motivation loss. Results: In independent models, low hopelessness buffered the association between depressive symptoms and suicidal behavior for our whole sample, blacks, and whites, whereas trait hope buffered for Hispanics and whites. Examined simultaneously, hope remained a significant moderator only in whites and hopelessness only in blacks. These findings suggest that etiological and outcome correlates of hope and hopelessness may differ by ethnicity. Conclusions: These findings may have implications for development of culturally targeted interventions for college students that strive to simultaneously reduce hopelessness and bolster hopefulness. 相似文献
