The impact of psychological distress on absence from work   总被引:3,自引:0,他引:3  
The aims of this study were to examine the impact of psychological distress on absence from work; to compare psychological distress and job satisfaction as predictors of absence; and to compare the relative effects of 2 components of psychological distress, depression and anxiety, on absence. Organizational records of absence over a 3-year period were obtained for 323 health service staff in the United Kingdom, who also completed self-report measures of psychological distress and job satisfaction at the beginning of the study and 2 years later. Psychological distress, particularly depression, was found to predict absence, with higher levels of distress predicting a greater number of days and number of times absent. Job satisfaction and psychological distress independently predicted levels of absence. The psychological distress-absence relationship was not moderated by demographic variables.  相似文献

As web instruction becomes more and more prevalent at universities across the country, instructors of ethics are being encouraged to develop online courses to meet the needs of a diverse array of students. Web instruction is often viewed as a cost-saving technique, where large numbers of students can be reached by distance education in an effort to conserve classroom and instructor resources. In practice. however, the reverse is often true: online courses require more of faculty time and effort than do many traditional classes. Based on personal experience teaching an online course in health care ethics for students in the Allied Health Professions, it is evident that there are both benefits and challenges in teaching online courses, particularly in ethics. Examples of benefits are (1) the asynchronous nature of web instruction allows students to progress through the course at their own pace and at times that are convenient given their clinical responsibilities; (2) web courses allow for a standardization of content and quality of instruction over a diversity of programs; and (3) examples can be tailored to the differing experiences of students in the course. Some challenges to teaching online ethics courses include (1) the fact that online instruction benefits visual learners and disadvantages those lacking good reading comprehension or strong writing skills; (2) developing meaningful student-student and student-instructor interaction; and (3) teaching ethics involves teaching a process rather than a product. Allowing students to apply their knowledge to real-world cases in their disciplines and encouraging them to share experiences from clinical practice is an effective way to meet several of these challenges. Building an online community is another good way to increase the interaction of students and their engagement with the material.  相似文献

Cognitive and psychomotor performance have traditionally been assessed in the laboratory. There is a need for an objective portable assessment tool to assess cognitive and psychomotor performance. This study investigated the viability of a portable psychometric test battery, in a controlled laboratory environment, possibly leading to use in the field. A randomised, double-blind placebo controlled, three-way crossover design was employed. 16 subjects received 50 mg/100 ml and 80 mg/100 ml of alcohol and alcohol placebo. Performance was assessed with a tracking task, and an attention task presented on a small ruggedised handheld computer. The attention task showed no significant training effects; however, an element of the tracking task did. Statistical significance, effect size, and test-retest reliability analyses are presented indicating sensitivity of the portable psychometric test battery to the impairing effects of two separate doses of alcohol. Ability to undertake wide-scale impairment testing in the field with meaningful results in the absence of baseline data collection may have wide reaching implications, particularly in relation to the assessment of drivers impaired by drug use.  相似文献

Protective factors (hope, spirituality, self-efficacy, coping, social support–family, social support–friends, and effectiveness of obtaining resources) against suicide attempts were examined in economically, educationally, and socially disadvantaged African American women (100 suicide attempters, 100 nonattempters) who had experienced recent intimate partner violence. Significant positive associations were found between all possible pairs of protective factors. Bivariate logistic regressions revealed that higher scores on each of the seven protective factors predicted nonattempter status; multivariate logistic regressions indicated that higher scores on measures of hope or social support–family showed unique predictive value for nonattempter status. Further, the multivariate model accurately predicted suicide attempt status 69.5% of the time. Partial support was found for a cumulative protective model hypothesizing a linear relationship between the number of protective factors endorsed and decreased risk for suicide attempts. Implications of these findings for community-based preventive intervention efforts and future research are discussed.  相似文献

We assess the importance of outline shape in mediating the recognition of living and nonliving things. Natural objects were presented as shaded line drawings or silhouettes, and were living and nonliving things. For object decision (deciding whether an object may be encountered in real life) there were longer response times to nonliving than to living things. Importantly, this category difference was greater for silhouettes than for shaded line drawings. For naming, similar category and stimulus differences were evident, but were not as pronounced. We also examined effects of prior naming on subsequent object decision performance. Repetition priming was equivalent for nonliving and living things. However, prior presentation of silhouettes (but not shaded line drawings) reduced the longer RT to nonliving things relative to living things in silhouette object decision. We propose that outline contour benefits recognition of living things more than nonliving things: For nonliving things, there may be greater 2-D/3-D interpretational ambiguity, and/or they may possess fewer salient features.  相似文献
