We develop a model of premium sharing for firms that offer multiple insurance plans. We assume that firms offer one low quality plan and one high quality plan. Under the assumption of wage rigidities we found that the employee's contribution to each plan is an increasing function of that plan's premium. The effect of the other plan's premium is ambiguous. We test our hypothesis using data from the Employer Health Benefit Survey. Restricting the analysis to firms that offer both HMO and PPO plans, we measure the amount of the premium passed on to employees in response to a change in both premiums. We find evidence of large and positive effects of the increase in the plan's premium on the amount of the premium passed on to employees. The effect of the alternative plan's premium is negative but statistically significant only for the PPO plans. 相似文献

This study examined the effect of previous romantic relationship involvement on later romantic relationship quality and tested whether adolescents' personality type (i.e., overcontrollers, undercontrollers, resilients) moderated this link. We answered our research questions in a sample of 320 Dutch participants (213 girls) who had a romantic relationship when they were 21 years old. At 12 years of age, their personality types were identified. At 21 years of age, participants reported their current romantic relationship quality (i.e., commitment, exploration, and reconsideration) and indicated the number of romantic relationships they had before. No main effects of the number of romantic relationships on current romantic relationship quality were found. There were significant interaction effects between personality types and the number of romantic relationships on romantic relationship quality. With more romantic relationship experiences, undercontrollers committed less to and explored less in their current romantic relationship. No such link was found for resilients and overcontrollers. 相似文献

目的探讨胃癌深层次护理在缓解胃癌患者手术前后焦虑中的效果评价。方法对150例胃癌患者进行术前调查,随机分为试验组80例和对照组70例,对照组采用传统的常规护理方法,试验组通过胃癌深层次护理干预,比较两组干预前后焦虑的发生率、疼痛评分、睡眠质量及术后满意率。结果干预后试验组和对照组重度焦虑发生率分别37.5%和54.3%,差异有统计学意义(P0.05)。护理干预前试验组和对照组疼痛评分比较,差异无统计学意义(P0.05);干预后疼痛评分试验组较对照组低,差异有统计学意义(P0.05)。试验组护理干预后手术当天和术后1周睡眠自测AIS量表评分高于对照组,差异有统计学意义(P0.05)。护理干预后,试验组与对照组满意度比较,差异无统计学意义(P0.05)。结论胃癌患者术前焦虑发生率高,以重度焦虑为主,在常规护理基础上进行胃癌深层次护理干预可减少焦虑发生程度,改善患者睡眠质量,缓解因焦虑产生的疼痛,有利于外科手术治疗的顺利完成。 相似文献

There is a growing literature that seeks to evaluate the role of “recovery capital” in the resolution of substance use disorders. In this study, a structured instrument (the Assessment of Recovery Capital), along with an assessment of social networks among 176 former illicit drug users and drinkers, is measured in three locations in England. There were relationships between recovery capital and vocational activity (training or employment), physical health, psychological health, and overall quality of life, with larger social networks associated with enhanced personal and social recovery capital. The study demonstrates high levels of personal and social well-being—manifesting in engagement in community activities and strong social networks—among persons engaged in recovery support activities that was not linked to time in recovery. 相似文献
