Alcohol and marijuana use are thought to increase sexual risk taking, but event-level studies conflict in their findings and often depend on reports from a limited number of people or on a limited number of sexual events per person. With event-level data from 1,856 sexual intercourse events provided by 297 college women (M age = 18 years; 71% White), we used multilevel modeling to examine associations between alcohol and marijuana use and condom use as well as interactions involving sexual partner type and alcohol-sexual risk expectancies. Controlling for alternative contraception use, partner type, regular levels of substance use, impulsivity and sensation seeking, and demographics, women were no more or less likely to use condoms during events involving drinking or heavy episodic drinking than during those without drinking. However, for drinking events, there was a negative association between number of drinks consumed and condom use; in addition, women with stronger alcohol-sexual risk expectancies were marginally less likely to use condoms when drinking. Although there was no main effect of marijuana use on condom use, these data suggest marijuana use with established romantic partners may increase risk of unprotected sex. Intervention efforts should target expectancies and emphasize the dose-response relationship of drinks to condom use.  相似文献

“Hookups” are sexual encounters between partners who are not in a romantic relationship and do not expect commitment. We examined the associations between sexual hookup behavior and depression, sexual victimization (SV), and sexually transmitted infections (STIs) among first-year college women. In this longitudinal study, 483 women completed 13 monthly surveys assessing oral and vaginal sex with hookup and romantic partners, depression, SV, and self-reported STIs. Participants also provided biological specimens that were tested for STIs. During the study, 50% of participants reported hookup sex and 62% reported romantic sex. Covariates included previous levels of the outcome, alcohol use, impulsivity, sensation seeking, and romantic sex. Autoregressive cross-lagged models showed that, controlling for covariates, hookup behavior during college was correlated with depression, Bs = .21, ps < .05, and SV, Bs = .19, ps < .05. In addition, precollege hookup behavior predicted SV early in college, B = .62, p < .05. Hookup sex, OR 1.32, p < .05, and romantic sex, OR 1.19, p < .05, were associated with STIs. Overall, sexual hookup behavior among college women was positively correlated with experiencing depression, SV, and STIs, but the nature of these associations remains unclear, and hooking up did not predict future depression.  相似文献

This invited commentary responds to recent criticisms of two validated and widely used sexual function questionnaires, the Female Sexual Function Index (FSFI) and the International Index of Erectile Function (IIEF) (Forbes, Baillie, &; Schniering, 2014 Forbes , M. K. , Baillie , A. J. , &; Schniering , C. A. ( 2014 ). Critical flaws in the Female Sexual Function Index and the International Index of Erectile Function . Journal of Sex Research , 51 , 485491 . doi: 10.1080/00224499.2013.876607 [Taylor &; Francis Online], [Web of Science ®] [Google Scholar]). We take issue with the conceptual arguments presented, selective review of published literature on both instruments, and conclusions drawn from methodologically flawed findings from an Internet-based study in a nonrepresentative group of Australian men and women. Alternative perspectives on the IIEF and FSFI are presented.  相似文献

Early copies of the Photographic Album of South African Scenery that was published between c.1880 and c.1888 by Robert Harris in Port Elizabeth consisted of 28 double-card pages with two, occasionally one, tipped-in photographs per page. During the near-decade of its production, the number of images increased, printed captions replaced handwritten captions and both the selection and arrangement of images became gradually more coherent and programmatic. The paper interprets these changes as Robert Harris’s attempt to construct a public identity for South Africa at the moment its economy and society were being transformed by the diamond mines at Kimberley and elsewhere that constitute the focus of the later form of the form Album. In the developed form of the Album, a narrative progression is suggested to move from Cape Town and the Western Province, to Port Elizabeth and the Eastern Province, to the Kimberley Diamond Fields, Natal, etc. In order to read this journey critically, the paper is arranged to demonstrate the constituent parts of this journey in the representation of cities and towns, laid out in grid plans on the African veld; the depiction of individual buildings with their expressive vocabulary of architectural style; and the idea of commerce – represented in street scenes, markets and seaports – and the facilitation of commerce through roads, bridges and mountain passes. The disproportionately large number of photographs of Kimberley, with both its mining operations and no less than three commercial markets, underlines the significance of commerce and industry in the new South African identity. The emphasis on commercial achievement in the Album leaves an obviously subordinate role for images of nature in both agriculture and landscape. Farming is represented through such exploitative practices as forest clearing and hunting, rather than the developed forms of agriculture of wine farming, sheep farming and wheat farming. And landscape in the Album is either a landscape subdued to the wants and needs of a settler population that would bludgeon its way through mountain passes or divert the course of rivers to facilitate commerce, or a landscape that is defined by the imported aesthetic conventions of the picturesque and sublime. Similarly, grouping the photographs of indigenous peoples that are scattered throughout the Album, one may see that their representation is entirely instrumental, divided crudely into roles of either war-like barbarians or pliant labourers. In these ways, the Photographic Album may be understood as a true mirror of the colonial achievement.  相似文献

This research extends prior work that examines self‐esteem as an outcome of protective behaviors against crime victimization by focusing instead on the moderating influence of self‐esteem on the relationship between the fear of crime and the decision to protect oneself from victimization. The fear of crime is conceptualized as two separate components (fear of victimization and perceived risk) in accordance with prior work. Self‐esteem is conceptualized as three separate components (worth, efficacy, and authenticity), and measured with a recently designed instrument for capturing each aspect of self‐esteem separately. Data are collected through surveys of a population at high risk for victimization (undergraduate college students). Logistic regression analyses demonstrate that self‐esteem does play a role for deciding whether to engage in protective behaviors, and that the specific components of self‐esteem moderate defensive behavioral outcomes differently. Specifically, the self‐worth, self‐efficacy, and authenticity components of self‐esteem influence the decision to carry protection, but not the decision to take a self‐defense class. Implications for both the fear of crime and self‐esteem literatures are addressed.  相似文献

Research has documented the stigma of obesity extensively, but little attention has been given to the study of stigma toward formerly obese individuals. The present study examines whether the stigma of obesity in romantic relationships carries over to formerly obese individuals by using primary data collected from a Midwestern university in the United States (N = 363). We consider how an individual's own body weight, demographic characteristics, familiarity, and attitudes affect the willingness to form a romantic relationship with a formerly obese person. Results suggest that obese individuals are less likely to hesitate about engaging in a romantic relationship with a formerly obese person than underweight or normal weight individuals, but only when attitudes toward obese and formerly obese individuals are controlled. In terms of demographic characteristics, men and African Americans are more likely to hesitate about forming a romantic relationship than their respective counterparts. More familiarity with currently obese family members and formerly obese close friends appears to reduce the stigma minimally. Greater social distance is also desired if weight loss is believed to be temporary.  相似文献

Blending high-quality and rigorous research with pure evaluation practice can often be best accomplished through thoughtful collaboration. The evaluation of a high school drug prevention program (All Stars Senior) is an example of how perceived competing purposes and methodologies can coexist to investigate formative and summative outcome variables that can be used for program improvement. Throughout this project there were many examples of client learning from evaluator and evaluator learning from client. This article presents convincing evidence that collaborative evaluation can improve the design, implementation, and findings of the randomized control trial. Throughout this paper, we discuss many examples of good science, good evaluation, and other practical benefits of practicing collaborative evaluation. Ultimately, the authors created the term pre-formative evaluation to describe the period prior to data collection and before program implementation, when collaborative evaluation can inform program improvement.  相似文献

A three-level growth-curve model was applied to estimate perceived impact growth trajectories, using multi-year data from project and school surveys on outcome and program implementation collected from 59 sites and approximately 1165 participating schools in the Safe Schools and Healthy Students Initiative. Primary interest is to determine whether and how project-level and school-level correlates affect schools’ perceptions of the Initiative's effectiveness over time when the effects of the pre-grant environmental conditions, grant operations, and near-term outcomes are considered. Coordination and service integration, comprehensive programs and activities for early childhood development, and change in school involvement were found to be significant predictors of school-perceived overall impact when the effect of poverty was considered. Partnership functioning, perceived importance of school resources, and school involvement were found to be significant predictors of school-perceived impact on substance use prevention when the effect of poverty was considered.  相似文献

Participants?? faces were covertly recorded while they rated the attractiveness of people, the decorative appeal of paintings, and the cuteness of animals. Ratings employed a continuous scale. The same participants then returned and tried to guess ratings from 3-s videotapes of themselves and other targets. Performance was above chance in all three stimulus categories, thereby replicating the results of an earlier study (North et al. in J Exp Soc Psychol 46(6):1109?C1113, 2010) but this time using a more sensitive rating procedure. Across conditions, accuracy in reading one??s own face was not reliably better than other-accuracy. We discuss our findings in the context of ??simulation?? theories of face-based emotion recognition (Goldman in The philosophy, psychology, and neuroscience of mindreading. Oxford University Press, Oxford, 2006) and the larger body of accuracy research.  相似文献

We present data on predictors of treatment outcome for 3200 consecutive referrals to a child and adolescent psychiatry clinic. Using Reliable Change Index (RCI) methodology, we divided children into those who, between intake and discharge, improved, stayed the same, or got worse according to clinician-rated impairment. Most predictors of improvement were related to parent variables (marital status, maternal anxiety, and ethnicity), while those associated with deterioration were tied to child status (extent of psychiatric comorbidity, history of placement in a self-contained classroom, and a prior trial of psychotropic medications). The implications of these findings for data-driven program development, clinic management, treatment planning, and systems of care are discussed.  相似文献
