目的 汉化护生临床实践反思问卷,检验其在实习护生中的信度和效度。
方法 基于Brislin模型对英文版临床实践反思问卷进行翻译。采用一般资料调查表、中文版护生临床实践反思问卷和反思功能问卷对550名实习护生进行调查,以检验其信效度。
结果 中文版护生临床实践反思问卷包括专业能力、内部动机来源、基于反思的自我管理、具有挑战性的临床情境、动态的组织氛围和动态的职业发展6个维度,共36个条目。探索性因子分析共提取6个公因子,累计方差贡献率为70.099%;验证性因子分析结果显示,χ2/df=1.292,RMSEA=0.033,CFI=0.977,TLI=0.974。量表Cronbach′s α系数为0.961,各维度Cronbach′s α系数为0.870~0.949,量表水平的平均内容效度为0.983,折半信度为0.853,重测信度为0.934。
结论 中文版护生临床实践反思问卷具有较好的信度和效度,可用于评估我国实习护生在临床实践中的反思能力。 相似文献

IntroductionDistance from anal verge of rectal tumors and their anatomical relationships contribute to determine the multidisciplinary therapeutic strategy based on the combination of radio-chemotherapy and radical surgery. Our aims are to investigate which is the most accurate method for the preoperative measuring of the distance from the anal verge in rectal tumors and if the pelvic MRI can substitute the classical instrumental methods.MethodsProspective study of diagnostic precision between flexible colonoscopy (FC), preoperative rigid rectosigmoidoscopy (pRR) and pelvic MRI in patients scheduled to radical surgery. Rigid intraoperative rectoscopy (iRR) was considered the reference test. The correlations between the different techniques and their determination coefficient as well as the intraclass correlation coefficient and the degree of agreement between the different tests were analyzed.Results96 patients (65% males), mean age (SD): 68 (14.1) years were included. 72% received neoadjuvant treatment. The mean distance to the anal margin measured by FC = 103.5 mm, was significantly greater than others, which had similar values: pRR = 81.1; MRI = 77.4; iRR = 82.9 mm (P < .001). A significant intraclass correlation was observed and there was high agreement between all pre- and intraoperative measurements except for the performed by FC, which overestimated the results. MRI provided more individualized and accurate information.ConclusionsThere is variability between the measurement methods, being colonoscopy the least reliable. MRI offers objective, comparable, accurate and individualized values that can replace those obtained by pRR for tumors of any location in the rectum. 相似文献

In our paper, the magneto-optical properties of a dichroic cholesteric liquid crystal layer with large values of magneto-optical parameter g and low values of dielectric permittivity were investigated. The solutions of the dispersion equation and their peculiarities were investigated in detail. The specific properties of reflection, transmission, absorption, rotation, ellipticity spectra and also the spectra of ellipticity and azimuth of eigen polarization were investigated. The existence of a tunable linear and nonreciprocal transmission band was shown. 相似文献

传统生理学教科书中"动脉血压随着远离心脏而逐渐降低"的相关表述不够准确。大量研究表明,动脉收缩压和脉压在由中心动脉向外周大动脉这一区段传播的过程中不仅没有逐渐降低,反而逐渐升高。这一现象可能与脉搏波反射等因素有关。笔者呼吁传统教科书中的相关表述应予以修正,使之更加准确,以避免对广大医学生或临床医生造成误导,同时脉搏波反射具有重要的生理及临床意义,应予进一步重视。 相似文献

Background
Accounts of cognitive processes in judgment and decision-making are frequently based on a dual-process framework, which reflects two qualitatively different types of processing: intuitive (Type 1) and analytical (Type 2) processes.Objective
The present study investigated the effects of bilateral transcranial direct current stimulation (tDCS) to the dorsolateral prefrontal cortex (DLPFC) on judgment and decision-making performance.Methods
Participants received anodal tDCS stimulation to the right DLPFC, left DLPFC or sham. There were 3 tasks: vignettes measuring heuristic thinking, belief bias syllogisms, and the cognitive reflection test (CRT), a measure of the ability to inhibit automatic responses to reach a correct solution. Fifty-four participants (mean age?=?24.63?±?4.46 years; 29 females) were recruited.Results
Results showed that anodal tDCS to the right DLPFC was associated with an increase in cognitive reflection performance (Type 2 processing) as compared to left DLPFC and to sham. Logic thinking was reduced following anodal tDCS to the left DLPFC.Conclusion
These findings are broadly consistent with a dual process framework, and cannot be explained by differences in cognitive ability and thinking style. The results demonstrate the involvement of the right DLPFC in cognitive reflection, and suggest the possibility of improving cognitive performance through tDCS. 相似文献10.
