Young adults' contraceptive practices: an investigation of influences

This study investigated young adults' contraceptive behaviors and attitudes through application of a comprehensive, theoretical framework. Specifically, a social-psychological approach to understanding preventive behaviors (e.g., contraceptive practices), was developed, incorporating the Health Belief Model and other factors, which offered a means for evaluating the extent to which contraceptive behaviors were influenced by individual and group characteristics. The study group consisted of 283 unmarried students at several schools who were, on average, 19 years of age. Results suggested that effective contraceptive behavior associated most strongly with respondents' perceiving relatively few barriers to their use of contraception, their maintenance of extensive interpersonal skills, and their regarding peer norms as consistent with effective contraceptive behavior. Findings also underlined a need for continuing education about sexuality and contraception. Dangerous misinformation prevailed regarding respondents' knowledge of areas that include anatomy, physiology, and appropriate use of effective contraceptive methods. Finally, results implied a need to consider broad behavioral, social, and interpersonal issues as they relate to young adults' effective contraceptive behavior. Future studies of contraceptive risk taking are encouraged to examine both individual and social factors affecting sexual and contraceptive practices if unplanned pregnancy is to be minimized, if not eliminated.     

Dietary concern, weight fluctuation and weight status: further explorations of the restraint scale

The theory of restrained eating predicts that the Dietary Concern and Weight Fluctuation factors of the Restraint Scale should correlate with percentage overweight. However, Drewnowski, Riskey and Desor (1982) recently found that only Weight Fluctuation did in fact. The current study replicated that of Drewnowski el al. using a population which more closely resembled the one used in prior research on restraint. Correlations were computed between Restraint scores and both overweight and weight suppression, a second validational criterion with which indices of restraint should be related. Furthermore, since Drewnowski et al.'s results imply that it is Weight History rather than Dietary Concern which might be responsible for behavioral differences in restrained and unrestrained normals, the history of overweight among these two groups was examined. Contrary to Drewnowski et al., Dietary Concern was more strongly related to overweight than was Weight Fluctuation. Both factors correlated with weight suppression. Restrained normals had a much greater history of overweight than unrestrained normals, suggesting that previously observed similarities in behavior between restrained normals and obese individuals might be due to characteristics associated with the former group's prior overweight rather than with their current level of cognitive restraint.     

Predictors of COVID-19 precautionary behaviors to protect people with disabilities

Disability is conceptualized using one of two major frameworks: the medical and the social model of disability. The medical model of disability describes disability as an individual issue in which the appropriate intervention is to remove the disability. The social model of disability describes disability as a social construction in which the appropriate intervention is societal change to increase accessibility. This study drew on models of disability to understand predictors of engagement in COVID-precautionary behavior prior to the vaccine to protect people with disabilities (PWD) from contracting COVID-19. Participants (n = 720) with and without disabilities (n = 77 and n = 633, respectively) completed an online questionnaire measuring disability beliefs, attitudes toward PWD, concerns about PWD contracting COVID-19, and engagement in behavior protecting PWD from contracting COVID-19. Medical model beliefs were negatively associated with behavior. In addition, negative attitudes toward PWD and low concern about PWD contracting COVID-19 fully accounted for the relationship. Social model beliefs were positively associated with behavior. In addition, positive attitudes toward PWD and greater concern about PWD contracting COVID-19 partially explained the relationship. These findings suggest that framing disability as a social construction rather than a medical issue could promote greater public health behavior to protect PWD from contracting COVID.

We argue that Shogan's critique, as well as that of Fox, fails to engage with the central focus of our article, which was to characterize and evaluate different approaches to lesbian ethics and to propose an alternative to the more familiar approaches.     

An evaluation of the reliability of probability judgments across response modes and over time

Despite the importance of probability assessment methods in behavioral decision theory and decision analysis, little attention has been directed at evaluating their reliability and validity. In fact, no comprehensive study of reliability has been undertaken. Since reliability is a necessary condition for validity, this oversight is significant. The present study was motivated by that oversight. We investigated the reliability of probability measures derived from three response modes: numerical probabilities, pie diagrams, and odds. Unlike previous studies, the experiment was designed to distinguish systematic deviations in probability judgments, such as those due to experience or practice, from random deviations. It was found that subjects assessed probabilities reliably for all three assessment methods regardless of the reliability measures employed. However, a small but statistically significant decrease over time in the magnitudes of assessed probabilities was observed. This effect was linked to a decrease in subjects overconfidence during the course of the experiment.
