Despite increasing incidence of HIV/AIDS, there has been no systematic review of correlates of condom use among heterosexual samples. To rectify this, the present study used meta-analysis to quantify the relationship between psychosocial variables and self-reported condom use. Six hundred sixty correlations distributed across 44 variables were derived from(More)
PURPOSE To test the hypothesis that ankles with functional instability will demonstrate slower muscular reaction times than their contralateral stable ankle (SA) and stable healthy controls to a simulated nonpathological ankle sprain mechanism. METHODS Nineteen male volunteers with a history of unilateral ankle sprain and functional ankle instability(More)
PURPOSE The aim of this study was to examine the effects of caffeine supplementation on multiple sprint running performance. METHODS Using a randomized double-blind research design, 21 physically active men ingested a gelatin capsule containing either caffeine (5 mg x kg(-1) body mass) or placebo (maltodextrin) 1 h before completing an indoor multiple(More)
A recent debate in the British Journal of Medical Psychology has considered the role of social cognitive models, such as the theory of reasoned action and the theory of planned behaviour, in understanding HIV-preventive behaviour. In this paper we clarify some of the assumptions involved in applications of social cognitive models. We briefly review(More)
A review of the literature concerning the relationship between religiosity and premarital sexual attitudes and behavior revealed inconsistencies in research findings and problems with methodology and operationalization of variables. A postal questionnaire to 527 16-18 year olds examined the associations between 6 models of religiosity (religious(More)
The aims of this study were to examine familiarization and reliability associated with a 40-m maximal shuttle run test (40-m MST), and to compare performance measures from the test with those of a typical unidirectional multiple sprint running test (UMSRT). 12 men and 4 women completed four trials of the 40-m MST (8 × 40-m; 20 s rest periods) followed by(More)
Beliefs concerning the spread of the human immunodeficiency virus (HIV) and preventive behaviors were examined in a sample of 351 sexually active Scottish teenagers. A postal questionnaire, including measures of variables specified by the health belief model (HBM) and preventive intentions, was employed. The relation between HBM measures and reported(More)
BACKGROUND The normal range of CD4 lymphocyte count varies among different ethnic groups. In populations with CD4 counts inherently lower than in the West, the Centers for Disease Control and Prevention (CDC) classification system of HIV-infected individuals may not be appropriate. No such criterion is currently available for ethnic south Indian(More)
Cases of 'imported malaria' into countries where malaria is not endemic are increasing and evidence suggests that non-use of malaria prophylaxis and lack of adherence are contributing to this increase. Non-adherence may be especially likely because chemoprophylaxis regimens require travellers to continue to take medication for 4 weeks after their return(More)
The authors investigated the extent to which Health Belief Model (HBM) measures can be used to predict subsequent sexual activity and consistency of condom use among teenagers, especially those who report having new sex partners. Results from a longitudinal survey of sex behavior and HIV-relevant cognitions among 258 sexually active 16 and 18 year olds in(More)
