Ability To Drive

The quality of drivers’ performance is one of the crucial components related to road safety. One of the key cognitive characteristics related to the ability to drive safely are executive functions. The main goal of the presented research is to propose a new method (Trace-route task) for assessment of executive functions in drivers. The present article discusses the results of two consecutive studies. Study one aims to determine the validity and reliability of the method used and includes 134 participants, equally divided in two groups—people with disturbances in executive functions and people from the general population. Study two aims to assess the ability of the method to distinguish drivers with risky behavior. It includes 1440 participants divided in two groups—people with and without actual risky driving behavior. The results from the studies show that people with different neurological or psychiatric diseases and drivers with different road violations demonstrate worse planning ability, working memory, decision making, and cognitive flexibility. This data show that the trace-route task method is a valid and reliable instrument for assessing executive functions and has the ability to distinguish people with risky driving behavior from those who drive safely. This study reveals that the proposed method can be used for implementation in the area of traffic psychology.

Background: As one of the most important components of curriculums, the educational environment provides learners with a forum in which they can learn communication skills and other abilities such as critical thinking and clinical problem-solving. To improve this environment and consequently upgrade medical education, the current environment must be evaluated. Objectives: In a quest to adapt a valid and reliable instrument for this purpose, this study aimed to assess the reliability and validity of the Persian translation of Dutch Residency Educational Climate test (D-RECT) to measure the quality of the educational environment in the main clinical wards of Shiraz University of Medical Sciences. Methods: In a cross-sectional study, a forward Persian translation of the D-RECT questionnaire was translated and back-translated by two bilingual expert panels, and its reliability was determined in a pilot study. Then, 100 residents working at internal medicine, surgery, pediatrics, and gynecology wards were selected randomly to fill out the questionnaire. Data were analyzed using SPSS version 21 software. Results: The Persian translation of D-RECT had acceptable validity, reliability, internal consistency, and reproducibility. The reliability of the questionnaire was confirmed by Cronbach’s α of 0.95. Convergent validity was 0.61 to 0.90. Among the wards evaluated in this study, the educational environment was significantly better in the pediatric ward than in the other wards. Conclusions: The Persian translation of D-RECT validated in the studied departments seems to be an effective, valid, and reliable instrument for evaluating and comparing the quality of the current educational environment for residents in Iran. This evaluation can help improve training.

Background:The lack of specific prosthetic-related outcome instruments for Spanish amputees must be addressed.Objective:To elaborate a culturally equivalent version of the Prosthesis Evaluation Questionnaire in the Spanish language.Study design:Cross-cultural questionnaire validation.Methods:Two-step process for cultural adaptation: forward and backward translations of English original and Spanish translated versions; assessment of both construct and criterion validity and reliability in a group of vascular amputees.Results:A total of 61 patients were recruited, 44 men (72.1%) and 17 women (27.9%), with a median age of 71.1 years (standard deviation: 7.7 years; range: 51–87 years). In the Prosthesis Evaluation Questionnaire–Spanish, the lowest scores were for gait and frustration, and the highest scores were for noise and stump health. Internal consistency of the questionnaire was acceptable (>0.70) for four of the scales used in the Prosthesis Evaluation Questionnaire but poor (<0.50) for the scales relating to appearance and stump health. Correlations with the quality-of-life levels as measured by the Short Form–36 were positive and mostly significant.Conclusion:Prosthesis Evaluation Questionnaire–Spanish could assess the quality of life in patients who have undergone vascular amputations and then been fitted with a prosthetic limb. The questionnaire shows adequate criteria validity when compared with other instruments for measuring quality of life.Clinical relevanceThe Prosthesis Evaluation Questionnaire–Spanish could be a valid and reliable instrument for assessing adaptation to prostheses in vascular amputees. The questionnaire adds information relevant to the patient and the physician and may identify cases with poor expected adaptation to the prosthesis.

Patient satisfaction with health services is used as a measure of the quality of patient care received. The emphasis on accountability and patient as consumer has contributed to the growing interest in studying patient satisfaction. Patient satisfaction with prenatal care services has not been extensively studied including instrumentation to develop a satisfaction scale. The purpose of this study was to develop a reliable and valid scale to measure satisfaction with prenatal care services in St. Petersburg, Russia, using the 6 satisfaction dimensions in Aday and Andersen’s Theoretical Framework (1974). It was conducted under the auspices of the World Health Organization, Healthy Cities Project. Although the study was conducted internationally, it provides a basis for further testing of reliability and validity in the United States. A convenience sample of 397 women with uncomplicated pregnancies and normal deliveries was studied (86% response rate). Content, construct, and predictive validity, and reliability testing using Cronbach’s alpha was conducted. The scale was found to be an adequate and theoretically sound measure of satisfaction with prenatal care services in Russia. However, rather than the 6 hypothesized satisfaction dimensions, Russian women identified 2 satisfaction subscales or measures for quality of prenatal care received. One was, as hypothesized, convenience, and the other was the doctor’s behavior.

PurposeThe purpose of this project was to determine the validity and reliability of the Healthcare Quality Perception (HQP) questionnaire tool designed to capture employees' perceptions of healthcare quality in Indian hospitals.Design/methodology/approachTwo hundred employees in private and public sector hospitals in India were randomly selected and given the HQP tool. It consisted of 38 Likert-scale items and six different subscales: (1) Planning and Documentation (n = 7); (2) Employee Participation in Quality Management Activities (n = 5); (3) Existence of Policies/Procedures/Guidelines (n = 5); (4) Quality and Patient Safety Management (n = 9); (5) Perceived Effect of Quality Improvement (n = 7) and (6) Training and Development Opportunities (n = 5). 156 completed questionnaires were received, demonstrating a 78% response rate. HQP tool subjected to statistical analysis to measure its reliability and validity. A p-value of less than 0.05 was considered as “significant.”FindingsFactor analysis pulled out six factors that conjointly demonstrated 66.4 % of the variance in healthcare professionals' (HCPs') perception of healthcare service quality in selected Indian hospitals. The overall Cronbach's alpha coefficient was measured at 0.959 for internal consistency reliability. This study demonstrates that the identified six critical factors are important determinants influencing HCPs' perception of the quality of healthcare services in private and public sector hospitals in India.Originality/valueThis study provides evidence for the reliability and validity of the newly developed HCP Scale for the assessment of employee perception of the quality of services offered in selected hospitals in India, with potential applications in other contexts.
