The Accuracy of Self-Reports of Condom Use and Sexual Behavior 总被引:5,自引:0,他引:5

In a study of the accuracy of self-reports of sexual behavior and condom use, 285 single, young adults in a large metropolitan area were interviewed once a week for 52 weeks, reporting on their sexual behavior each week. At 1-, 3-, 6-, and 12-month intervals, the individuals also provided self-reports of the number of times they had engaged in sex and the number of times they had used condoms since they began participating in the study. These self-reports were compared with aggregates of the weekly data, which served as a comparison standard for accuracy evaluation. The results indicate a fairly high level of accuracy in self-reports, but with 2% to 5% outliers who are highly inaccurate. The results tend to favor the assessment of sexual behavior over moderate time durations (3 or 6 months) rather than short or long durations (1 month or 12 months) when trying to maximize self-report accuracy. Accuracy was attenuated for individuals who tended to engage in sex frequently, especially at the 12-month time durations. 相似文献

Exposure to an outgroup member voicing criticism of his or her own group fosters greater openness to the outgroup’s perspective. Research suggests that this effect owes its influence to a serial process in which participants’ perception of the risk involved in voicing internal criticism leads to an increase in the perceived credibility of the speaker. The credibility makes it possible for the speaker to be viewed as open-minded, which subsequently inspires greater hope. This process culminates in an increased openness to the outgroup. These findings have been restricted to the Israeli-Palestinian conflict, but here we examine their generalizability to racial conflict in the United States. Results reveal that White Americans exposed to internal criticism expressed by a Black authority figure express greater openness to African-American perspectives on race relations and are more willing to support policies of racial equality. Replicating past research, this effect is serially mediated by risk, credibility, and hope. 相似文献

We show how to construct certain L
M, T
-type interpreted languages, with each such language containing meaningfulness and truth predicates which apply to itself. These languages are comparable in expressive power to the L
T
-type, truth-theoretic languages first considered by Kripke, yet each of our L
M, T
-type languages possesses the additional advantage that, within it, the meaninglessness of any given meaningless expression can itself be meaningfully expressed. One therefore has, for example, the object level truth (and meaningfulness) of the claim that the strengthened Liar is meaningless. 相似文献

It has long been established that there is a linear and positive relationship between relative deprivation and prejudice. However, a recent experiment suggests that the converse of relative deprivation, relative gratification, may also be associated with prejudice (S. Guimond & M. Dambrun, 2002). Specifically, the evidence suggests that the usual test for a linear relationship between relative deprivation-gratification and prejudice might conceal the existence of a bilinear relationship. This function, labeled the V-curve hypothesis, predicts that both relative deprivation and relative gratification are associated with higher levels of prejudice. This hypothesis was tested with a representative sample of South Africans (N=1,600). Results provide strong support for the V-curve hypothesis. Furthermore, strength of ethnic identification emerged as a partial mediator for the effect of relative gratification on prejudice. 相似文献

This article discusses the genetic counseling protocols which were developed and counseling issues that have arisen in the first 2 years of evaluating a large kindred with a BRCA1 mutation. The rationale for the development of the genetic counseling protocols and specific genetic counseling visual aids are presented and discussed. The protocols and counseling aids can serve as models for other programs offering cancer susceptibility testing. The observations of study counselors about study subject concerns and responses to genetic testing at the time of the pretest and posttest counseling sessions are presented. 相似文献

Marketers are interested in the first buyers of new products, given their important role in driving wider community adoption. This is especially the case for new entertainment products, like new or relocated sports teams who must quickly build fan connections and loyalty, given the importance of crowds and social networks in adding value to the entertainment experience. Fans choose to connect with sports teams for numerous reasons; however, fan development in the context of a new team has rarely been examined. This paper examines the diversity and similarity among inaugural fans of an expansion team. A large sample (n = 1724) was classified into five segments revealing how each varies in their brand associations, satisfaction, identification and involvement. By analysing key dimensions (relationship identifiers) that characterise how consumers connect with a new team, the authors provide new insights about the nature of consumers in the context of a new sports team. Furthermore, the five segments were found to be distinct cohorts, with sufficient variation between them to warrant variant marketing approaches to achieve the outcome of committed, long‐term fans.

In empirical studies of human eye movement behavior during reading, it is common to compute various summary measures from the data, but these measures are typically not evaluated with respect to corresponding measures of baseline performance. The authors present a method for deriving an appropriate baseline by mapping the actual behavior to a random perturbation of the text being read, and they find surprising similarities between the baseline and the empirical data. The practical message from these findings is that the importance of a particular factor in explaining either empirical or simulated eye movement patterns should be evaluated using an appropriate baseline. In addition to this methodological point, the authors suggest that eye movement behavior in reading may be constrained by the properties of an eye-guidance system that has adapted to the coarse-grained statistical properties of written language. 相似文献

The error-related negativity (ERN/Ne) and error positivity (Pe) have been associated with error detection and response monitoring. More recently, heart rate (HR) and skin conductance (SC) have also been shown to be sensitive to the internal detection of errors. An enhanced ERN has consistently been observed in anxious subjects and there is some suggestion that the ERN is related to general negative affective experience (NA). The ERN has been source localized to the anterior cingulate cortex-a structure implicated in the regulation of affective, response selection, and autonomic resources. Thus, the findings that autonomic measures and affective distress are related to response monitoring are consistent with anterior cingulate cortex function. In the present experiment, we sought to evaluate more comprehensively the relationship between self-reported negative affect and error-related physiology in a between-groups design. Results indicate that high NA was associated with significantly greater ERN and error-related SCR, and smaller Pe. These results are discussed in terms of anterior cingulate cortex function, psychopathology, and response monitoring. 相似文献
