PURPOSE To better understand why adolescents initiate sexual activity at early ages, we conducted a systematic literature review guided by eight key elements outlined in an integrative theoretical framework. METHODS Using the matrix method for literature reviews, we extracted-from 69 published studies-statistically significant and nonsignificant findings(More)
UNLABELLED Little is known about the quality of online sexual health information, how young people access the Internet to answer their sexual health questions, or an individual's ability to sort through myriad sources for accurate information. OBJECTIVE The purpose of this study was to determine how college students search for online sexual health(More)
OBJECTIVE To examine sexual health disparities between blacks and whites in a national sample of US college students. PARTICIPANTS AND METHOD SUMMARY: Analyses utilized secondary data from 44,165 nonmarried undergraduates (aged 18-24; M = 20.1) responding to the Spring 2007 American College Health Association-National College Health Assessment; 64% were(More)
This study examined sexual risk behaviors/outcomes among college students with online partners only, offline partners only, and both online/offline partners. Students with both online/offline partners were more likely to report sexually transmitted diseases, unintended pregnancy, and more vaginal/oral sex partners. Sex with online partners was not riskier(More)
We investigated the cognitive and emotional reactions resulting from a human papillomavirus-related illness threat (i.e. testing positive for human papillomavirus) and the potential behavioral implications resulting from these psychosocial processes among men (N = 536). Structural equation modeling was used to explore a theoretical model explaining human(More)
OBJECTIVE To describe and illustrate missing data mechanisms (MCAR, MAR, NMAR) and missing data techniques (MDTs) and offer recommended best practices for addressing missingness. METHOD We simulated data sets and employed ad hoc MDTs (deletion techniques, mean substitution) and sophisticated MDTs (full information maximum likelihood, Bayesian estimation,(More)
We assessed online sexual health information quality and accuracy and the utility of web site quality indicators. In reviewing 177 sexual health web sites, we found below average quality but few inaccuracies. Web sites with the most technically complex information and/or controversial topics contained the most inaccuracies. We found no association between(More)
OBJECTIVE To introduce the state of the art of structural equation modeling (SEM). METHOD This primer is organized in a manner allowing readers to review any one of 5 freestanding sections. RESULTS SEM maintains several advantages over regression and other multivariate techniques. Through a 2-step modeling process, SEM strengthens research by allowing(More)
