The current study was designed to gain a better understanding of the nature of the relationship between substance use and sexual risk taking within a community sample of women (N = 1,004). Using confirmatory factor analysis, the authors examined the factor structure of sexual risk behaviors and substance use to determine whether they are best conceptualized as domains underlying a single, higher order, risk-taking propensity. A 2 higher order factor model (sexual risk behavior and substance use) provided the best fit to the data, suggesting that these 2 general risk domains are correlated but independent factors. Sensation seeking had large general direct effects on the 2 risk domains and large indirect effects on the 4 first-order factors and the individual indicators. Negative affect had smaller, yet still significant, effects. Impulsivity and anxiety were unrelated to sexual health risk domains.  相似文献

The purpose of this study was to compare African American and non-African American hepatitis C virus (HCV) patients on self-reported symptoms of HCV liver disease and psychosocial characteristics commonly affected by it in a sample of 309 patients enrolled in a randomized controlled trial. African Americans (n = 196) rated a higher reliance on religion/spirituality for coping with HCV compared to non-African Americans. This study’s findings are a basis for encouragement of public health efforts and programs to seek partnerships with African American faith and religious communities to identify and treat undiagnosed cases of HCV and promote HCV awareness.  相似文献

Written language knowledge that lower SES children have acquired from their environment before formal instruction was investigated. Complete data were collected from four and five year old children enrolled in a headstart program. Data concerning each child's knowledge of written language were individually collected through the use of interview techniques as well as informal and standardized assessments including: Book Handling Knowledge (Goodman, 1981), Sand Test (Clay, 1976), Preschool Children's Concept of Reading (Goodman, 1981) and Preschool Children's Concept of Writing (Goodman, 1981).

The results were compared with the results from an earlier study (Robeck & Wiseman, in press) conducted with a middle SES group of children enrolled in a day care center. Demon strated behaviors indicated that the two groups of preschool children were acquiring reading and writing knowledge. The children from the headstart group were learning the same things as the children from the private day care center, however there were differences between the two groups of children in the range and number of behaviors observed. The study suggests that children from not only different socio‐economic groups but children from the same socio‐economic group enter school with wide differences in their written language knowledge.  相似文献

Due to the benefits of voice and creativity on organizations’ effectiveness, scholars have tried to understand the reasons why employees engage in voice and creativity and determine the antecedents of these behaviors, including the role of personality. Previous literature, however, has shown inconsistent results about the effect of personality on voice and creativity. Addressing these inconsistencies, the authors use a meta-analytic approach to examine these relationships and to test potential boundary conditions that might exist in these relationships. This study also seeks to provide empirical support for the previous theoretical claims of similarity between voice and creativity. Clarifying these points, the results of this meta-analysis showed that Openness to Experience, Extraversion, and Conscientiousness are good predictors of creativity and voice. The findings also reveal similar directions and magnitudes of effects sizes in most of the relationships between the Big Five, voice, and creativity, which appears to support the similarities between voice and creativity. The moderation results provide further information about the role of gender differences, the sample type (student/employee sample), and the source of rating (self/other reporting) in these relationships.  相似文献
