Previous work on perceived risk, particularly a study by Fischhoff et al. (1978), is critically examined with reference to its applicability to specific health related issues. Judgments were obtained from 159 subjects of 15 health‐related items in terms of perceived risk, benefit, and a number of risk characteristics based on the Fischhoff et al. research. In addition, demographic details concerning sex of respondent, seat belt usage, smoking status, and birth order were collected. Using regression analyses it was found that the direction of the risk‐benefit relationship was dependent on the issue being judged. Risk was found to be better explained by ratings of likelihood of mishap and likelihood of death as a consequence of mishap. Benefit was poorly explained by the risk characteristics and demographic data. However, subject group characteristics were shown to be important influences on risk and benefit perception in certain situations. The implications of these results for understanding behavioral decisions involving risk in relation to specific activities are discussed.

SummaryFifty-seven women (mean age = 23·5 years), half of whom used an oral contraceptive, completed Moos' menstrual distress questionnaire at each of the three menstrual phases. In addition they kept menstrual diary cards for 50 days, recording days on which menstrual blood loss occurred. During an intermenstrual phase, they completed: a general information questionnaire with questions on menstrual, socialization and demographic variables; Eysenck's personality inventory; the multidimensional health locus of control scale; the Bern sex role inventory; and a measure of preventive health behaviour. Analyses investigating the effects of pill use and psychological factors on the incidence and intensity of menstrual distress found few significant associations between these measures, especially when symptom changes over the menstrual cycle were the dependent variables. The implications of these results for the aetiology of menstrual distress are discussed.
