Background: Students are a significant source of data for the evaluation of clinical instructors' performance. This study was undertaken with the aim of adaptation and validation of the Persian version of the Maastricht Clinical Teaching Questionnaire (MCTQ). The main objective of the researchers in this study was to evaluation the psychometric properties of the Persian version of the Maastricht Clinical Training Questionnaire (P MCTQ) in Iran, considering cultural and social differences. Materials and Methods: This methodological study was conducted from 2019 to 2021 at four teaching hospitals affiliated with Sabzevar University of Medical Sciences, Iran. Qualitative and quantitative face and content validity, and construct validity methods were used for the validity evaluation. Stability and internal consistency methods were used, respectively, for the reliability evaluation of the questionnaire. Exploratory Factor Analysis (EFA) stage, 264 students studying in the fields of nursing, midwifery, anesthesiology, operating room, emergency medicine, and laboratory sciences completed the P MCTQ. Results: The value of scale content validity index (0.92) is indicative of the overall content validity of the questionnaire. EFA extracted a single factor structure that could explain the overall variance of the clinical education structure at about 76.61%. The alfa and intraclass correlation values were equal to 0.98 and 0.82, respectively, indicating the excellent internal consistency and high overall stability of the questionnaire. Conclusions: The P MCTQ is a valid and reliable tool for the evaluation of the teaching performance of clinical instructors. [ABSTRACT FROM AUTHOR]

Background: Organizational ethics focuses on the importance of how organizations behave when faced with specific situations and decisions. This study aims to identify and prioritize organizational ethics indicators in Imam Khomeini Hospital Complex (IKHC) in Iran. Materials and Methods: This was a mixed method research project. To recognize hospital ethics indicators, 18 semistructured interviews were conducted and 38 indicators were identified through thematic analysis. In the next stage, a quantitative approach was adopted to use the importance performance matrix for data analysis. This part was a descriptive survey with a statistical population consisting of nurses, medical, clinical, and administrative staff. The questionnaire was distributed using the random sampling method, and a total of 349 samples were collected. Results: Based on the interviews and open coding, 73 themes were identified for organizational ethics indicators and classified into two main groups: "ethics drivers in hospital" and "personal ethics." After measuring content validity, 35 indicators of organizational ethics in IKHC were examined in terms of importance and performance. The results showed that nine indicators had high importance and poor performance, 11 had high importance and performance, nine had low importance and performance, and finally six indicators had low importance and high performance, and according to these findings, practical suggestions were put forward. Conclusions: Based on the identified indices and by applying importance performance analysis, it is recommended to continually assess the status of ethics in hospitals and offer strategies for improving organizational ethics.

Background: Disrespect and abuse during childbirth is regarded as harassment of women and a violation of their rights. The aim of this study was to assess the psychometric properties of the disrespect and abuse questionnaire in Iranian parturient women. Materials and Methods: This cross-sectional study was conducted on 265 postpartum women in both private and public hospitals in Tabriz, Iran. The scale was translated from English into Farsi. In the quantitative face validity, the impact score was determined for each item. Moreover, in the quantitative content validity, the Content Validity Ratio (CVR) and Content Validity Index (CVI) were assessed based on the comments of experts on the relevance, clarity, and simplicity of items (CVI) and the necessity of items (CVR). Construct validity was assessed through exploratory and confirmatory factor analyses. Results: In the face validity assessment, all items received a minimum impact score of 1.5. In assessing the content validity, all the items attained the minimum acceptable value of CVR (>0.69) and CVI (>0.79). According to the exploratory factor analysis, the Disrespect and Abuse Questionnaire has 23 items and five factors, including abandoning the mother, improper care, mother's immobility, not talking to the mother, and mother's deprivation. The construct validity of the scale was confirmed by the confirmatory factor analysis, in which X2/df <5 and root mean square error of approximation <0.08. Conclusions: The Farsi version of the disrespect and abuse questionnaire can be used as a valid tool for assessing instances of lack of respectful maternity care in the postpartum period.

Background: According to the importance of physical activity in the child's physical and mental development and cognitive health, developing a valid, reliable, and comprehensive assessment tool for children's physical activity is mandated. The purpose of this study is the translation, cross-cultural adaptation, and validation of the Persian version of the Thailand Physical Activity Children Survey questionnaire to measure the level of physical activity in children aged between 6-9 years in Iran. Methods: This study consisted of three stages, first, the questionnaire translation into Persian language and modification of the sections according to the Iranian culture, then the evaluation of the questionnaire via a pilot study, and finally, assessing the reliability and validity of the tool. Participants of the pilot study were 250 healthy children, aged 6 to 9 years, meeting eligibility criteria, recruited through a stratified cluster sampling method from schools across Tehran. Results: The Persian version of the questionnaire demonstrated an acceptable content validity (Content Validity Index between 0.88-1). The test-retest reliability reported the Intra-Class Correlation coefficient in the acceptable range in all sections (between 0.71-1). Cronbach's alpha was reported 0.993, which indicated excellent internal consistency. Conclusions: According to the acceptable validity and reliability of the Persian version of the Thailand Physical Activity Children Survey for children aged 6-9 years, it is recommended in research and surveillance studies to determine the level of physical activity of children of that age group in Iran.

Background: There is no validated measurement tool to assess vaginal symptoms (VS), sexual matter (SS), and quality of life (QOL) among Persian-speaking women. This study aimed at translating and assessing the validity and reliability of the Persian version of the International Consultation on Incontinence Questionnaire for Vaginal Symptoms (PICIQ-VS). Materials and Methods: In this cross-sectional study, after obtaining permission from the International Consultation on Incontinence Questionnaire (ICIQ) Advisory Board, the English version of ICIQ-VS was translated into Persian per a standard translate and back translate process, and the validity and reliability were studied. Two hundred women with and without pelvic organ prolapse were asked to complete the PICIQ-VS (mean age: 52.1, range: 22-84 years). A panel of 10 experts evaluated the content and face validity of the questionnaire. Cronbach's alpha examined the internal consistency reliability of the measure. To evaluate the test-retest reliability, we redistributed the questionnaire among 30 patients 2 weeks after their initial visit using intra-class correlation coefficient (ICC). Results: Content and face validity of the questionnaire was confirmed after some light modification (content validity ratio ranged from 0.69 to 1.00, and content validity index ranged from 0.79 to 1.00). PICIQ-VS showed an acceptable internal consistency and stability reliability (VS: α = 0.64, ICC = 0.84; SM: α = 0.69, ICC = 0.88; and total scale: α = 0.72, ICC = 0.91, respectively). Significant differences were observed between the asymptomatic and symptomatic groups for VS and the total score (P < 0.05). Conclusion: In the light of the results, interestingly, PICIQ-VS could be utilized as a valid and reliable tool to assess the VS among Persian-speaking women, both in research and clinical practice.

Background: No instrument specifically designed to investigate the caring self-efficacy of nurses in pediatric wards was found. The aim of the present study was therefore to develop a scale to evaluate pediatric wards nurse's caring self-efficacy. Materials and Methods: In this study, an exploratory, sequential, mixed method was used in 2015 in Iran. Data collected from 27 semi-structured interviews with nurses in pediatric wards were analyzed using conventional content analysis. The initial version of the scale was obtained with 65 items. Face validity was determined using impact score and content validity using the Content Validity Index (CVI) and Content Validity Ratio (CVR). The construct validity of the scale was investigated using exploratory factor analysis with 305 nurses in pediatric wards. The concurrent validity of the scale was acquired using the General Self-Efficacy Scale. Internal consistency and test--retest reliability were also examined. Results: The scale-CVI (S-CVI) (average) was 0.85. The 14 items with a CVR and CVI of less than 0.51 and 0.70, respectively, were deleted and the final 51-item scale was approved. All 51 items had good impact score (>1.50). In the final scale, four subscales were extracted using construct validity. The concurrent validity of the scale was also obtained (r = 0.77, p < 0.001). The total Cronbach-s α correlation coefficient of the scale was 0.96 and test--retest reliability was 0.98. Conclusions: The Pediatric Ward Nurses' Caring Self-Efficacy (PWNCSE) scale developed in this study is a practical, reliable, and valid scale to evaluate pediatric ward nurses' caring self-efficacy.

Backgrounds: Fear of compassion is one of the psychological variables in the nursing profession that can be a barrier to providing appropriate services to patients. This research was done in order to assess psychometric properties, construct validity, reliability of fear of compassion scales and to introduce suitable measures for experts and researchers in the healthcare-related fields. Materials and Methods: In this study, 216 nurses (117 males and 99 females) were chosen with a multistage cluster sampling method between June 2016 and Feb 2017. Lisrel-8 and SSPS-18 were used for data analysis. The construct validity of the fear of compassion scales was assessed using confirmatory factor analysis. To assess the divergent and convergent validity of the fear of compassion scales, the compassion for others, depression, anxiety, stress, burnout, and cognitive emotion regulation questionnaires were used. Results: The results of confirmatory factor analysis showed that the single-factor model of fear of compassion scales (for others, from others, and for self) is a better fit to the data. Furthermore, these three scales had a positive and significant correlation with anxiety, depression, stress, burnout, and unhealthy cognitive-emotion regulation strategies, and negative and significant correlation with compassion for others and healthy cognitive-emotion regulation strategies. In addition, the Cronbach's alpha coefficient for fear of expressing compassion to others was 0.85, and 0.95 and 0.96 for fear of responding to compassion from others and fear of self-compassion, respectively. Conclusions: This study provides additional evidence for the psychometric properties of fear of compassion scales in Iranian nurses. [ABSTRACT FROM AUTHOR]

Background: The precise measurement of childbirth satisfaction demands a reliable tool specifically designed for maternal care and birth satisfaction. It was designed to measure the degree of women's satisfaction with childbirth. The purpose of the present study was to translate and analyze the psychometric properties of the Birth Satisfaction Scale-Revised (BSS-R) in Iranian women. Materials and Methods: This is a methodological cross-sectional study. Five health centers in various regions of Kashan were affiliated to Kashan University of Medical Sciences, Kashan, Iran. Two hundred and twelve mothers who were referred to the health centers and had childbirth during the last year were included. The face and content validity were obtained after backward-forward translation of the Iranian version of BSS-R by 12 faculty board members in midwifery and reproductive health fields. The construct validity of the tool was determined using confirmatory factor analysis on 212 women in the postpartum period. The internal consistency and reliability of the tool was evaluated by Cronbach's alpha coefficient and intraclass correlation coefficient (ICC). The collected data were analyzed in SPSS (version 16.0) and EQS 6.1. Results: The result of face and content validity was minor modifications in some words. Confirmatory analysis results indicated that there was an acceptable fit with a three-factor model. Cronbach's alpha was estimated for the whole tool 0.74, and the alpha of the three subscales ranged from 0.698 to 0.801. ICC for determining reliability was 0.77. Conclusion: The Iranian version of BSS-R was a reliable and valid tool for assessing the women's satisfaction with their childbirth care. [ABSTRACT FROM AUTHOR]

Background: This study was carried out to design and validate a questionnaire to measure the majority of factors influencing food choices among adults in Iran. Methods: A sequential exploratory mixed-method approach was applied to develop the initial item pool of the Food Choice Determinants Questionnaire (FCDQ) starting with a qualitative study to explore the food choice dimensions and its components. Designing the initial questionnaire using these dimensions and the 36-item Food Choice Questionnaire (FCQ) was then performed. The face, content, and construct validity were also assessed. The construct validity of the questionnaire was assessed using the exploratory factor analysis (EFA). Cronbach's alpha was applied for each main theme to examine the internal consistency. Results: After content and face validity process, a 60-item FCDQ was developed with total items' content validity index (CVI) of 0.69 indicating a reasonable level. The Cronbach's alpha coefficients for each of the six constructs in the scale have shown satisfactory internal consistency. Conclusions: This instrument is valid and reliable to measure food choice determinants in adults and could be applied to design interventions aiming to better food choice. [ABSTRACT FROM AUTHOR]

Background: There are no proper tools for measuring pregnancy-specific stress in Iranian population. The aim of this study was psychometric evaluation of the Persian version of Revised Prenatal Distress Questionnaire (NuPDQ) for the first time in Iranian society. Materials and Methods: In a descriptive-analytic study, 269 pregnant women completed the NUPDQ at Obstetrics clinics of Mazanderan Province, Iran. The reliability of the 12-item NuPDQ and 17-item NuPDQ was reevaluated using Cronbach's alpha and internal consistency. Concurrent validity was assessed using the Spielberger state-anxiety Inventory. Moreover, exploratory factor analysis was used to assess the structural factors of the questionnaire. Results: Factor analysis revealed that the 12-item NuPDQ consisted of four areas in the second trimester including medical and financial problem, physical symptoms, infant health, and parenting with the explained variance of 64.15%. The Persian version of 17-item NuPDQ consisted of 5 areas in the third trimester, including medical and financial problems, physical symptoms, infant health, parenting, and labor and delivery with an explained variance of 61.94%. In addition, interclass correlation coefficient in all 4 areas and overall scale score exceeded 0.90. Finally, the reliability was high based on Cronbach's alpha of 0.78 for 12-item NuPDQ and 0.79 for 17-item NuPDQ. Conclusions: The Persian version of 12-item NuPDQ in the second trimester and 17-item NuPDQ in the third trimester, as well as all the extracted subscales, had a good validity and reliability for assessing pregnancy specific stress in Iranian society and can be used in clinical practice.

Background: Designing cancer prevention programs needs information on knowledge, attitude, and practice of the community. Unfortunately, this information is not available in Iran. Materials and Methods: We developed a questionnaire (NUTCANKAPQ) to assess the knowledge, attitude, and practice of Iranian women regarding cancer prevention dietary habits. We recruited women who had referred to public health-care centers in Tehran, Iran. To assess validity, we applied face, content, and construct validity methods. We performed test--retest approaches to assess reliability, and internal consistency of the questionnaire was assessed through Cronbach's alpha and intraclass correlation coefficients (ICCs). Results: Qualitative content validity was carried out by an expert panel, and internal consistency was deemed satisfactory (Cronbach's alpha, >0.6). We also observed high reliability in the questionnaire (ICC = 0.85). The mean (± standard deviation) scores for knowledge, attitude, and practice of study participants were 28.3 (±14.1), 67.1 (±18.9), and 53.7 (±8.3), respectively. The result of exploratory factor analysis, Kaiser--Meyer--Olkin (KMO), implied that the model was reasonably fit (KMO > 0.6). The final questionnaire included seventy items. Conclusion: NUTCANKAPQ is a valid and reliable tool for the assessment of cancer-related nutrition knowledge, attitude, and practice among the Iranian population. Application of NUTCANKAPQ may provide important clues for policy-making and improvement of cancer prevention programs among the Iranian population. [ABSTRACT FROM AUTHOR]

Background: This study is to evaluate swallowing problems (dysphasia) in multiple sclerosis (MS) patients; the importance of using tools that are durable and appropriate is well understood. One of the most trusted tools is the dysphagia in multiple sclerosis (DYMUS) test. The aim of this study was to prepare a Persian version and to evaluate the validity and reliability of the test. Materials and Methods: This methodological study was conducted on 236 MS patients in Southeast of Iran from August 2015 to February 2016. After translation and cultural adaptation of the test in Persian, the validity of this test was determined using expert opinions accordance with the International Quality of Life Assessment Project. In addition, exploratory factor analysis (EFA) was performed with varimax rotation. The confirmatory factor analysis (CFA) was conducted and the goodness of fit indices was calculated. Moreover, to test the reliability, Cronbach's alpha coefficient and intraclass correlation coefficient (ICC) were used. Results: In total, 236 MS patients were included in the study (81 males and 155 females). All the questions in the test's Persian version obtained an acceptable face and content validity (content validity ratio = 1, Scale content validity index/Ave = 1). EFA revealed that the scale has two factors (solid-liquid) with 67.5% cumulative variance. CFA indicated a good fit to the intended two-factor structure, and the ratio of Chi-square to the degree of freedom was 1.79, and the root mean square error of approximation was 0.058. The internal consistency of total test indicated the appropriate level (Cronbach's alpha coefficient = 0.775), and test-retest reliability total questionnaire was found to be ICC = 0.985, indicating its high reliability. Conclusion: The results of this study indicated that the Persian version of the DYMUS questionnaire had good reliability and validity for patients with MS. [ABSTRACT FROM AUTHOR]

Background: There is not a valid Persian tool for measuring the decision-making competency of patients. The aim of this study is to evaluate the face and content validity of the MacArthur Competence Assessment Tool for the treatment of Iranian Persian-speaking patients. Methods: To assess the validity of the Persian version of the tool, a self-administrated questionnaire was designed. The Lawshe method was also used for assessing each item. Content validity ratio (CVR) and content validity index (CVI) were used to assess the content validity quantitatively. According to the experts' judgment, questions with a CVR =0.62 and CVR <0.62 were maintainable and unmaintainable, respectively. Results: The questions were designed in a manner to achieve the desirable result (CVR =0.62). The CVI scale (S-CVI) and CVI (S-CVI/Ave) were 0.94 (higher than 0.79). Thus, the content validity was confirmed. Conclusions: Since capacity assessments are usually based on physician's subjective judgment, they are likely to bias and therefore, with this suitably validated tool, we can improve judgment of physicians and health-care providers in out- and in-patient cases.

Background: Low health literacy (HL) of patients has obtained more attention as a risk factor for poor adherence to treatment and adverse outcomes in chronic disease's management particular in diabetes care. Diabetes Numeracy Test-15 (DNT-15) has been developed specifically for this purpose. The objective of the current study is to evaluate psychometric properties of Iranian (Persian) version of the DNT-15. Methods: The shortened version of the DNT (15-items) was completed by 120 patients with diabetes. The Kuder--Richardson Formula 20 for internal consistency was conducted. Content validity, criterion-related validity, and construct validity were also evaluated. Results: The average score on the DNT was 72% and took an average of 25 minutes to complete. The DNT-15 had a very good internal reliability (KR-20 = 0.90) and also content validity (content validity ratio: 089 and content validity index: 0.86). Conclusions: The DNT-15 (Persian version) is a reliable and valid measure of diabetes-related numeracy skills for Iranian patients with diabetes; however, additional studies are needed to further explore the association between diabetes-specific numeracy and acculturation and their impact on diabetes-related outcomes in Iranian population.

Objectives: Glasgow Outcome Scale Extended (GOSE), Galveston Amnesia and orientation Test (GOAT) and Disability Rating Scale (DRS) are three popular outcome measure tools used principally in traumatic brain injury (TBI) patients. We conducted this study to provide a Farsi version of these outcome scales for use in Iran. Methods: Following a comprehensive literature review, Farsi transcripts were prepared by "forward-backward" translation and reviewed by subject experts. After a pretest on a few patients, the final versions were obtained. 38 patients with closed head injury were interviewed simultaneously by two interviewers. Main statistics used to assess validity and reliability included "Factor analysis" for construct validity, Cronbach's alpha for internal consistency, and Pearson Correlation and Kappa Coefficient for inter-rater agreement. Results: Factor analysis for Farsi-GOAT (FGOAT) revealed 5 independent factors with a total distribution variance of 80.2%. For Farsi-DRS (FDRS), 3 independent factors were found with a 92.3% variance. The Cronbach's alpha (95% confidence interval) was 0.84 (0.763- 0.919) and 0.91 (0.901- 0.919) for FGOAT and FDRS, respectively. Pearson Correlation between total scores of two raters was 0.98 and 0.97 for FGOAT and FDRS, in order. Kappa coefficient (95% CI) between outcome rankings of raters was 0.73 (0.618-0.852) and 0.68 (0.594-0.770) for FGOAT and FDRS, respectively. As for Farsi-GOSE scale, Kappa value was 0.4 (0.285-0.507) for 8- level outcome ranking and improved to 0.7 (0.585-0.817) for 5-level scale. We found a good correlation between FDRS and FGOSE predicted prognoses (Spearman's rho= 0.74, 95% CI: 0.676-0.802). Conclusions: FDRS and FGOAT had appropriate validity and reliability. The 8-level outcome FGOSE scale disclosed a low inter-rater agreement, but a suitable observer agreement was achieved when the 5-level outcome was applied. [ABSTRACT FROM AUTHOR]

The result of exploratory factor analysis, Kaiser–Meyer–Olkin (KMO), implied that the model was reasonably fit (KMO > 0.6). The final questionnaire included seventy items. Conclusion: NUTCANKAPQ is a valid and reliable tool for the assessment of cancer-related nutrition knowledge, attitude, and practice among the Iranian population. Application of NUTCANKAPQ may provide important clues for policy-making and improvement of cancer prevention programs among the Iranian population. [ABSTRACT FROM AUTHOR]
