目前,实施社区首诊制有重要的意义在于,可以缓解看病难、看病贵问题,适应人口老龄化的需求,改善流动人口的健康状况,以及减少私人诊所和药店不规范医疗带来的危害.但是,首诊制的实施也必然面临一定的困难.因此,应积极倡导医保制定向社区倾斜的政策,鼓励社区提高医务人员的技术水平、服务质量,并且完善双向转诊制度.  相似文献

该文采用问卷法和社会测量法相结合的方法,以班级为单位对484名3~9岁儿童的气质和同伴关系类型的关系进行研究。结果表明:3~9岁儿童同伴关系类型已形成分化,其中被忽视儿童和被拒绝儿童所占总体样本的比例分别为16.9%和9.6%,比例较高值得重视。儿童气质对同伴交往类型的形成影响很大,四种同伴关系交往类型在气质各维度上方差检验都达到了差异显著,有着明显不同的气质特点。  相似文献

This study examined whether a virtual avatar could be perceived as a real human by patients with mental disease, especially schizophrenia, as well as whether a virtual avatar could be applied to acquiring patients' behavior characteristics in a short conversation situation. The virtual avatar has been used for various applications which need to communicate with other person or to train or educate by showing humanlike behavior. Recently, many researches have shown that the virtual avatar technology has been enhanced and the avatar could be perceived like real human. A virtual avatar, standing in a virtual room, was designed for this study. Tasks to approach, initiate a talk, and answer to avatar's questions was assigned to the 11 patients with schizophrenia. As behavioral parameters in the virtual environment, the interpersonal distance and the verbal response time were acquired. In addition, the Positive and Negative Syndrome Scale (PANSS) for patients was administered in order to investigate the relationship between patients' symptomatic characteristics and behavior parameters. The interpersonal distance was negatively correlated with the negative syndrome scale, a subscale of PANSS, which is consistent with previous research reporting the relationship between interpersonal distance and a real person's image. The verbal response time, however, was not correlated with any other subscale of PANSS. After analyzing subitems of the negative syndrome of PANSS, two positive correlations were found: one was with blunted affect and the other was with poor rapport. We concluded that the virtual avatar could be perceived as a real human by schizophrenic patients and the avatar could draw the schizophrenic patients' behavior characteristics.  相似文献

This research investigated the relationships of the Dark Triad traits, humor styles, and schadenfreude with 169 participants who completed the Short Dark Triad, the Humor Style Questionnaire, and a measure of schadenfreude. Significant correlations imply that those with salient dark traits (psychopathy, Machiavellianism, narcissism) elicit pleasure from others' misfortune. Additionally, schadenfreude can be a product of self-defeating and aggressive humor styles. Indirect effect analysis revealed the significance of the indirect effect of the measured aggressive humor style on the Dark Triad's direct effects on schadenfreude. These results imply that those with salient Dark Triad traits enjoy others' misery as a means to undermine them. Hence, individuals with salient Dark Triad traits tend to engage in downward social comparison.  相似文献

The purpose of the study was to determine if the CAAS could be used with middle school students. Currently no study has been done for the application of CAAS on middle school students. We examined the reliability and validity of the Career Adapt-Ability Scale (CAAS) in Macau for middle school and high school students. The CAAS consists of four scales, each with six items, which measure concern, control, curiosity, and confidence. We tested the internal consistency and factor structure with 270 middle school students and 188 high school students. We also compared students' performance on CAAS in terms of gender and age. The results indicated that internal consistency estimates for the subscale and total scores were good for both high school and middle school students. The factor structure was quite similar to the one computed for combined data from 13 countries (Savickas & Porfeli, 2012). In addition, we found that high school students scored significantly higher than middle school students on the CAAS scales. Based on the results, the CAAS-Macau Form appears ready for use by researchers and practitioners who wish to measure adaptability resources among middle school and high school students in Macau.  相似文献

This report examined whether Virtual Reality Exposure Therapy (VRET) could be used in the treatment of posttraumatic stress disorder (PTSD) symptoms in the aftermath of a serious motor vehicle accident. Six individuals reporting either full or severe subsyndromal PTSD completed 10 sessions of VRET, which was conducted using software designed to create real-time driving scenarios. Results indicated significant reductions in posttrauma symptoms involving reexperiencing, avoidance, and emotional numbing, with effect sizes ranging from d=.79 to d=1.49. Indices of clinically significant and reliable change suggested that the magnitude of these changes was meaningful. Additionally, high levels of perceived reality ("presence") within the virtual driving situation were reported, and patients reported satisfaction with treatment. Results are discussed in light of the possibility for VRET to be useful in guiding exposure in the treatment of PTSD following road accidents.  相似文献
