Abstract

Objective: Melanoma is the second most common cancer diagnosed among 15- to 29-year-olds. This pilot study assessed behaviors, barriers, and beliefs relevant to sun exposure and protective behaviors. Participants: The sample comprised 153 undergraduate students at a large state university in western New York. Methods: Participants completed an online survey about sun safety habits, barriers to using sunblock, and beliefs about tanning and sun exposure. Results: Response rate was 90.8% (n = 139). Most students (87.8%) reportedly spent ≥ 3 hours per day outside in the summer, but only 17.3% reported always using sunblock during this time. Sixty percent reported recent indoor tanning and 41% reported more than 10 lifetime sunburns. The greatest barrier to using sunblock was forgetting (84.2%). Conclusions: Demographics coupled with inconsistent and low levels of sunblock use, high annual prevalence of indoor tanning, and multiple lifetime sunburns indicate that this sample is at high risk for skin cancer.  相似文献

Stereotypies, defined here as monotonous and undirected behaviors (e.g., walking in place, foot swinging) were observed in inpatients at an intensive-treatment psychiatric center. Stereotypies were found to be especially sensitive to situations; the most stressful contexts produced the most stereotypies. In situations that seemingly made patients anxious, stereotypies were repetitive and typically took the form of incipient flight movements. In contexts where patients were apparently bored, their stereotypies were dominantly nonrepetitive and somewhat playful, suggesting a function of increasing arousal. Frequencies of stereotypies did not distinguish most diagnostic types (e.g., schizophrenia, organic brain damage) from each other. But stereotypies seemed to be markedly less characteristic of patients diagnosed as situation adjustment types, by far the most benign diagnosis of pathology represented in this sample. Overall, stereotypies showed promise as practical and reliable indices to be used as adjuncts to traditional measures of pathology.  相似文献

Documentation in evaluation research consists of written material, in human- or machine-readable form, pertaining to the plans, activities, and results of the project. It is argued here that good documentation is essential for effective management of evaluations, and for responsible reporting of the research procedures and findings. Documentation relating to electronic data processing activity is especially important. The purpose of this paper is to stimulate consideration and discussion of documentation, and to emphasize its importance in evaluation research. The role of documentation in the planning and control functions of project management is reviewed, and the importance of documentation in the assessment of research quality with respect to objectivity, validity, and replicability is discussed. Reasons for poor documentation are considered. An outline of documentation required in different phases of research projects is provided, and recommendations for improving the quality of documentation are presented.  相似文献

This study employs a sample of 309 recently married couples to discover predictors of cohabitation and cohabital duration before marriage. On the individual level religiosity and sex-role traditionalism were negatively related to the probability of having cohabited for both husbands and wives. However, couple-level analyses revealed that these variables significantly predictnot cohabiting only whenboth partners are religious or traditional. A history of previous divorce is related to a greater propensity to cohabit only when the wife has been married before, but the husband has not. No variables were significantly related to cohabital duration.  相似文献

This study examines the impact that experiencing harsh physical discipline in childhood and engaging in problem behaviors during adolescence and young adulthood have on experiencing and perpetrating intimate violence. Using LISREL 7, we tested a model based on social learning theory, Freudian theory, and theories of deviance. The 608 cases analyzed are from a longitudinal study of adolescents conducted in 1982 and 1992–1993. The results suggest that harsh physical punishment in childhood is directly related to greater perpetration of violence against an intimate partner later in life. The enactment of problem behaviors in adolescence and young adulthood was also found to increase the level of perpetration of violence against an intimate partner. In addition, harsh physical punishment in childhood was found to be indirectly but significantly related to increased perpetration via the intervening variables of adolescent and young adult problem behavior. We hypothesized that perpetration and victimization are significantly related to one another bidirectionally, but the results only support that greater levels of perpetration lead to increased levels of victimization.  相似文献

We evaluated aesthetic (lawn quality), biological (weeds and insect pests), and economic (management costs) effectiveness of a commercial (managed by a professional company), consumer (managed using consumer lawn care products following labeled instructions), integrated pest management (IPM) (pesticide applications based on monitoring and thresholds), organic (monitoring and need-based organic and natural product applications), and an untreated lawn care program. Percent weed cover was the lowest in the commercial followed by IPM, organic, and consumer programs. The commercial program had lower white grub density than all other programs, and the organic program had lower white grub density than the untreated program. The commercial program had the highest lawn quality while the untreated program had the lowest. The IPM and organic programs did not differ significantly in lawn quality, but both rated significantly higher than the consumer program. Annual costs were highest in the commercial ($382/0.05 ha) followed by the organic ($305/0.05 ha), IPM ($252/0.05 ha), and consumer program ($127/0.05 ha), respectively. We conclude that the commercial program produced the highest lawn quality, and weed and insect control, and was the most expensive. The IPM and organic programs were cheaper than the commercial program and produced slightly lower lawn quality. Although the consumer program was the cheapest, it produced the lowest weed control and lawn quality among treated lawns.  相似文献

Quality of housing plays one of the key roles in a public health research, since inadequate housing may have direct or indirect negative impact on health. Higher satisfaction with housing was shown to be associated with higher income, higher age, a smaller family, higher education, being female and being an owner of a dwelling. The aim of our study is to identify the multiple sources of the satisfaction with housing in population of urban slums and rural areas in Dhaka, Bangladesh. We have used a combined variable “Housing Satisfaction”, containing nine items related to satisfaction with different types of housing facilities (water, electricity, toilet etc.). Ordinal as well as binary multiple logistic regression models were applied to predict housing satisfaction. Rural residents (with 90 % house ownership) were much more satisfied with their housing than urban slum dwellers. Those respondents who perceived their area as “Very bad/Bad” to reach medical care reported significantly higher levels of housing dissatisfaction. Low satisfaction with available facilities (education, health services, etc.) as well as the adjacent neighbourhood being perceived as negative for own health showed as well a strong predictive effect on housing dissatisfaction. The major findings of our study showed a complex relationship between housing satisfaction and the quality of basic facilities including the reachability of medical care. Understanding the factors which lead to satisfaction with housing and residential environment is crucial for planning successful and effective housing policies.  相似文献
