Background: Professional identity is a vital component of medical education that affects the future practice of medical students. There is a notice of the lack of a reliable and valid Persian scale to measure the students' readiness for professional identity.Objective: This present study aims to determine whether or not the PSIQ can be adapted for Persian healthcare professions.Methods: A cross-sectional study was performed among medical students (years of 4-7) in Shiraz medical school. A total of 175 students completed the Persian version of PSIQ using convenience sampling. Categorical confirmatory factor analysis (CCFA) and Cronbach's alpha coefficient were used to investigate the questionnaire's validity and reliability. Moreover, R.3.6.2 software, by using the lavaan and semPlot packages in it, was used for data analysis and the path diagram.Results: The indices of the goodness of fit of the model were used for the professional self-identity, which including root mean square error of approximation (RMSEA), Tuker-Lewise index (TLI), and comparative fit index (CFI) ( RMSEA=0.055, CFI=0.996, and TLI=0.994). The Cronbach's alpha coefficients for these three factors of "profession-specific tasks," "generic attributes," and "inter-personal tasks" subscales were 0.762, 0.622, and 0.747, respectively (p-value<0.05). The internal consistency of the whole questionnaire measured by Cronbach's alpha was 0.873. The set of these fit statistics show that the hypothesized three-factor model fits the sample data. Therefore, all nine items were significantly loaded on the three domains (Profession specific tasks, Generic attributes, Interpersonal tasks). Conclusion: The Persian translated version of the PSIQ may be an appropriate, valid and reliable tool for assessing medical students' health professional self-identity attitudes in Iran.
Background: cardiovascular diseases are among the principal causes of mortality and morbidity worldwide. Prevention, early diagnosis and treatment can play an important role in reducing complication of cardiovascular diseases. Objectives: Considering increasing popularity of cardiac computed tomography CT angiography (CTA) in one side and also magnetic esonance angiography (MRA) as gold standard modality on the other side, we decided to perform this meta-analysis study to compare cardiac CTA and MRA in evaluating left ventricular volumes. Method: this study is a systematic review in which we included all studies with inclusion criteria and without exclusion criteria up to 30 December, 2019. Studies were selected after searching on different databases and articles in bibliography of included studies. Obtained studies were screened for quality. Required data were extracted and were then analyzed via STATA 11 statistical package. Results: among 90 articles obtained in primary search, finally 19 studies entered data extraction and synthesis. Based on our meta-analysis, standardized mean difference was -0.09 (95% CI -0.2, 0.02) for end systolic volume (ESV), -0.10 (95% CI -0.22, 0.01) for end diastolic volume (EDV), 0.10 (95% CI -0.01, 0.22) for ejection fraction (EF) and -0.09 (95% CI -0.23, 0.04) for stroke volume (SV). Conclusion: Results of this systematic review and meta-analysis showed that there is no statistically significant difference between CTA and MRA in evaluating ESV, EDV, EF and SV. Based on our findings, it can be interpreted that CTA has similar accuracy with MRA in evaluating ventricular volumes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
