The Power of Prestige: Why Young Men Report Having more Sex Partners than Young Women

In a survey of 48 men and 61 women from a southwestern US college, the gender difference in reported number of sex partners was mediated by the degree to which individuals felt that men and women who had many sexual partners were prestigious. In addition, men cared about the quantity and quality of their sex partners more than women did and these two factors were also related to reported number of sexual partners. The gender difference in reported sex partners is not veridical; it can be accounted for with attitudinal measures related to status and sex that are more common in men than women. Results are discussed in terms of understanding biased reporting in young American men and women.     

Determining risk in pediatric research with no prospect of direct benefit: time for a national consensus on the interpretation of federal regulations

United States federal regulations for pediatric research with no prospect of direct benefit restrict institutional review board (IRB) approval to procedures presenting: 1) no more than "minimal risk" ( section sign 45CFR46.404); or 2) no more than a "minor increase over minimal risk" if the research is commensurate with the subjects' previous or expected experiences and intended to gain vitally important information about the child's disorder or condition ( section sign 45CFR46.406) (DHHS 2001). During the 25 years since their adoption, these regulations have helped IRBs balance subject protections with the pursuit of scientific knowledge to advance children's welfare. At the same time, inconsistency in IRB application of these regulations to pediatric protocols has been widespread, in part because of the ambiguity of the regulatory language. During the past decade, three federally-charged committees have addressed these ambiguities: 1) the National Human Research Protections Advisory Committee (NHRPAC) (Washington, DC), 2) the Institute of Medicine (IOM) Committee on the Ethical Conduct of Clinical Research Involving Children (Washington, DC); and 3) the United States Department of Health and Human Services Secretary's Advisory Committee for Human Research Protections (SACHRP) (Washington, DC). The committees have reached similar conclusions on interpretation of language within regulations section sign section sign 45CFR46.404 and 406; these conclusions are remarkably consistent with recent international recommendations and those of the original National Commission for the Protection of Human Subjects of Biomedical and Behavioral Research (1977) report from which current regulations are based. Drawing on the committees' public reports, this article identifies the ethical issues posed by ambiguities in regulatory language, summarizes the committees' deliberations, and calls for a national consensus on recommended criteria.     

An information-motivation-behavioral skills model of adherence to antiretroviral therapy.

HIV-positive persons who do not maintain consistently high levels of adherence to often complex and toxic highly active antiretroviral therapy (HAART) regimens may experience therapeutic failure and deterioration of health status and may develop multidrug-resistant HIV that can be transmitted to uninfected others. The current analysis conceptualizes social and psychological determinants of adherence to HAART among HIV-positive individuals. The authors propose an information-motivation-behavioral skills (IMB) model of HAART adherence that assumes that adherence-related information, motivation, and behavioral skills are fundamental determinants of adherence to HAART. According to the model, adherence-related information and motivation work through adherence-related behavioral skills to affect adherence to HAART. Empirical support for the IMB model of adherence is presented, and its application in adherence-promotion intervention efforts is discussed.     

The relation between recognition memory and classification learning

Two experiments investigated the relation between recognition memory and classification learning. The subjects were instructed that they would see a series of random-dot patterns and later would be asked to classify or to recognize the patterns. Following study, the subjects performed a classification task, a recognition-memory task, or both. It was found that classification-learning instructions were superior to recognition-memory instructions for the classification task, but that there was little or no effect of instructions on the recognition task. When subjects performed both recognition and classification tasks, there was no relation between saying “old” to a probe and correctly classifying it, except with old exemplars, and then only when the initial instructions had been to expect a recognition-memory test. Overall, the data show that classification and recognition can be experimentally separated. In addition, classification is often statistically independent of recognizing that items are old. These observed relations provide some constraints for the further development of models of classification learning and recognition memory.     

Social reinforcement: A treatment component in verbal self-instructional training

This study investigated the effects of noncontingent social reinforcement on social and academic behaviors in grade school children. Twenty-four children in the second through fifth grades were selected on the basis of teacher ratings of disruptive behavior. Subjects were divided into (a) a high social reinforcement verbal self-instructional (VSI) training group, (b) a low social reinforcement VSI group, and (c) a no-contact control group. Children in VSI groups were removed from their classrooms during four 40-minute periods and given VSI training. Significant between-groups differences on measures of social reinforcement were found indicating its successful manipulation. While none of the dependent measures indicated significant differences between experimental groups, a consistent pattern of difference scores emerged giving limited support to the hypothesis that noncontingent social reinforcement contributed to behavioral gains. Results are discussed in terms of the need for future research on the effects of rapport on treatment outcome.Both authors wish to express their thanks to the Missoula public school administration, principals, psychologists, and teachers. Appreciation is also due to Matthew Firpo and Anita Fisher for their help in this project.     

The California Family Health Project: IV. Family structure/organization and adult health.

This research explores the relationships between each of four "domains" of family life and the health of husbands and wives in a community-based sample of 225 families. In this article we report the association between Family Structure/Organization and adult Health. This family domain refers to the architecture of the family or the structural frame of roles and rules within which the family operates. Interrelationships among 13 self-reported, family Structure/Organization scales are described, using principle components analysis (PCA) and multidimensional scaling analysis (MDS). Derived, joint-spouse or couple Structure/Organization variables also were created using inter-battery factor analysis. The PCA yielded a poor solution, whereas the MDS yielded a good two-dimensional solution, which roughly displayed the scales in a circular pattern for both husbands and wives. The analyses indicated that no single dimension or set of separate subdimensions adequately described the Structure/Organization variables. All 13 scales than were associated with a battery of 14 adult health scales for husbands and wives separately, using canonical correlation. Different aspects of family Structure/Organization were correlated with health for husbands and wives: Organized Cohesiveness, Sex Role Traditionalism, Role Flexibility and Shared Roles for husbands; and Organized Cohesiveness and Differentiated Sharing for wives. Different patterns of health scores also emerged by gender, with behavioral indicators, such as Smoking and Drinking, more salient for husbands, and mood indicators, such as Anxiety and Depression, more salient for wives.
