Patients and Methods: Validity and reliability of Iranian version of Coping Self-efficacy Scale (CSES) were measured by a cross-sectional study. Content validity, reliability and cultural equivalency were appraised through qualitative and quantitative study on 260 participants who have type 2 diabetes. Results: Reliability and validity of the scale and its four subscales, such as “stop unpleasant emotions and thoughts” (a = 0.92) “used problem-focused coping” (a = 0.71), Self-efficacy on diabetes problem solving (a = 0.74) and “get support from friends and family” (a = 0.67) were approved explicitly by a psychometric analysis;these show that the scale was slightly valid and reliable on the study setting. An intraclass correlation coefficient was satisfactory (p < 0.001). Criterion validity between total scale and metabolic control Index (HbA1c) of type 2 diabetic patients was significant (p < 0.001) and showed indirect correlation with the domains of the scale. Conclusion: Study findings supported the reliability and validity of the Iranian version of new Coping Self-efficacy-24 for measuring Coping Selfefficacy among Iranian type 2 diabetic patients. Based on our finding, we would like to recommend appropriate interventions in the future.展开更多

文摘目的基于第二版前列腺影像报告数据系统(PI-RAVS V2)对比双参数磁共振成像(BP-MRI)和多参数磁共振成像(MP-MRI)对前列腺癌(PCa)的诊断价值。方法选取2015年3月至2017年12月南京医科大学附属淮安第一医院收治的66例未经治疗临床怀疑PCa的患者进行MRI检查,包括T2加权成像(T2WI)、扩散加权成像(DWI)及动态对比增强磁共振成像(DCE-MRI),均经前列腺活检确定病理结果。两名放射科医师基于PI-RADS V2对BP-MRI及MP-MRI方案的诊断性能进行评估。结果病理证实27例PCa,其中23例位于外周带,4例位于移行带。BP-MRI检测PCa的灵敏度、特异度、准确度、阳性预测值、阴性预测值分别为90.6%(25/27)、97.7%(38/39)、92.4%(61/66)、95.8%(23/24)、94.7%(36/38),MP-MRI为87.2%(23/27)、95.3%(36/39)、93.9%(62/66)、89.3%(25/28)、90.5%(34/43)。结论与常规MP-MRI方案相比,3.0 T BP-MRI方案具有相似的诊断精度,检查时间较短且无需使用对比剂。
