Psychometrics of Persian Version of the Ageism Survey Among an Iranian Older Adult Population During COVID-19 Pandemic

Background: Studies have revealed an increase in discrimination, neglect, and abuse among the older adult population during this period. This study assessed the validity and reliability of the Persian version of the ageism survey instrument tested on a sample of the Iranian older adult population during coronavirus disease (COVID-19) pandemic. An important move in counteracting ageism is to classify the ageism scale comprehensively by employing adequate psychometrics.Methods: The Persian version of the ageism scale was developed using a two-step procedure. The first step involved translating and revising the original scale to develop a Persian version of the ageism scale. The second step involved assessing the psychometric features of the newly adapted scale using construct validity through exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) and thereafter assessing the reliability through the average inter-item correlation (AIC), Cronbach's alpha. The sample consisted of 400 older adults (age 65 and older), who were recruited through online data collection, with samples for EFA and CFA randomly selected from the total samples.Results: The Persian version of the ageism survey has three factors: age-related deprivation with five items, dignity with three items, and employment with three items; all of which explained 57.02% of the total variance. The outcome of the EFA was verified by the CFA, with internal consistency reliability being excellent (Cronbach's alpha was 0.725, 0.698, and 0.708 for the three factors).Conclusion: This study specifically offers a restructured three factors Persian version of the ageism survey for Iranian older adults with acceptable construct validity and reliability.

Background: Experiencing moral distress is traumatic for nurses. Ignoring moral distress can lead to job dissatisfaction, improper handling in the care of patients, or even leaving the job. Thus, it is crucial to use valid and reliable instruments to measure moral distress. Objective: The purpose of this study was to determine the reliability and the validity of the Persian version of the Moral Distress Scale–Revised among a sample of Iranian nurses. Research design: In this methodological study, 310 nurses were recruited from all hospitals affiliated with the Qazvin University of Medical Sciences from February 2014 to April 2015. Data were collected using a demographic questionnaire and the Moral Distress Scale–Revised. The construct validity of the Moral Distress Scale–Revised was evaluated using principal component analysis and confirmatory factor analysis. Internal consistency reliability was assessed with Cronbach’s alpha. Ethical considerations: This study was approved by the Regional Committee of Medical Research Ethics. The ethical principles of voluntary participation, anonymity, and confidentiality were considered. Findings: The construct validity of the scale showed four factors with eigenvalues greater than one. The model had a good fit ( χ2(162) = 307.561, χ2/ df = 1.899, goodness-of-fit index = .904, comparative fit index = .927, incremental fit index = .929, and root mean square error of approximation (90% confidence interval) = .049 (.040–.057)) with all factor loadings greater than .5 and statistically significant. Cronbach’s alpha coefficients were .853, .686, .685, and .711for the four factors. Moreover, the model structure was invariant across different income groups. Discussion and conclusion: The Persian version of the Moral Distress Scale–Revised demonstrated suitable validity and reliability among nurses. The factor analysis also revealed that the Moral Distress Scale–Revised has a multidimensional structure. Regarding the proper psychometric characteristics, the validated scale can be used to further research about moral distress in this population.

Introduction It is required to have validated instruments in health science students that identify unhealthy habits and assess the impact of educational interventions and programs aimed at promoting a healthy lifestyle. Objective To evaluate the validity and reliability of an instrument to measure medical students' lifestyles. Methods A lifestyle questionnaire was developed using the Delphi technique by a group of experts. The final questionnaire was applied to 332 students of the School of Medicine of the Ricardo Palma University in 2017. A preliminary examination was carried out to assess preconditions for construct validity—including the correlation matrix, the Kaiser Meyer Olkin statistic, and the Bartlett sphericity test. Factor analysis was used for construct validity, and the possible resulting factors were extracted through the principal component analysis. Cronbach's alpha coefficient was calculated to assess the instrument reliability. Results In this study, 41.6% of participants were men with a mean age of 20 years (standard deviation = 3). The preconditions for the factor analysis were a Kaiser Meyer Olkin coefficient = 0.773 and a significant Bartlett sphericity test. For the 47 items of the final questionnaire, the factor analysis showed an explained variance of 56.7% with eigenvalues greater than one. Cronbach's alpha was 0.78. The final questionnaire could assume values between -23 to 151 points. Based on a cut point of 71 points, the prevalence of students with an unhealthy lifestyle was 73.6%. Conclusion The developed instrument has acceptable validity and reliability to measure lifestyle in medical students. For external validation, studies in other university populations are suggested.

Abstract Background Postpartum maternal functioning has the potential to affect the quality of interaction between mother and child. A proper assessment of maternal functioning requires a comprehensive and accurate tool. The objective of this study was to prepare a Persian version of the Barkin Index of Maternal Functioning (BIMF) and evaluate its psychometric properties in order to determine its applicability in Iranian mothers. Methods The BIMF was translated into Persian and then culturally adapted for Iranian women. After evaluating face and content validity, to perform factor analysis, a cross-sectional study was conducted using the Persian version of BIMF. The data was collected from two unique groups of 250 mothers (in all 500 mothers) who had infants 2 to 12-months old and who were selected using a two-stage cluster sampling method. Factor analysis, Pearson’s correlation, intra-class correlation coefficients (ICC), composite reliability (CR) and Cronbach’s alpha were employed in order to evaluate structural validity and reliability. Results Exploratory factor analysis resulted in a five-factor structure consisting of 20 items. Subsequently, confirmatory factor analysis (X 2/ df = 1.61, RMSEA = 0.050, GFI = 0.91, CFI = 0.91) confirmed that the Persian version had satisfactory goodness of fit. Reliability and internal consistency were confirmed with a CR of 0.77, an ICC of 0.87 and a Cronbach’s alpha of 0.81. Conclusions The findings indicated that the Persian version of the BIMF is a valid and reliable instrument for assessing maternal functioning among Iranian mothers.

Abstract Background Dealing with the spiritual needs of patients has been recognized as one of the principles of holistic care in nursing. Therefore, it is necessary for nurses to deal with the spiritual issues of patients. Also, a valid and reliable scale is needed to measure nurse-provided spiritual care. So the purpose of this study was to determine the validity and reliability of the Persian version of the “Nurse Spiritual Care Therapeutics Scale” in Iranian nurses. Method In a methodological study, English version of the Nurse Spiritual Care Therapeutics Scale was translated into Persian by forward–backward translation procedure. Face validity was assessed by cognitive interview, and content validity was assessed by a panel of experts. In addition, construct validity was assessed by exploratory factor analysis. The participants were 188 nurses working in different adult wards. Reliability was measured using the Cronbach’s alpha and stability reliability was assessed using the internal correlation coefficient (ICC). Results In assessing the construct validity, two factors with eigenvalues greater than 1 were identified, which explained 58.47% of the total variance. Cronbach’s alpha value was 0.932, and ICC was 0.892. Conclusion As a result, the Persian version of the Nurse Spiritual Care Therapeutics Scale shows a good validity and reliability. Therefore, this scale can be used to evaluate spiritual care at the bedside in Iran.

Background and objectives Nurses’ caring behaviors, professional activities, and behaviors for the benefit of patients, influence patients’ perception of care and satisfaction with the quality of care provided. Caring behaviors of nurses are contextual and various factors such as patients’ social structure, lifestyle, culture, and interests, as well as their biographical, social, and physiological characteristics, can influence perceptions of caring behaviors of nurses, as caring behaviors are an interactive and mental process between patients and nurses. This study was conducted to provide a transcultural translation and psychometric analysis of Caring Behaviors Inventory (CBI) among nurses in Iran. Methodology Transcultural translation of the 16-item CBI was performed. Then, face validity (qualitative), content validity (quantitative and qualitative), and construct validity were examined in a cross-sectional study of 509 patients. A demographic questionnaire and the 16-item CBI were sent to enrolled patients via online questionnaires. The reliability of the instrument was assessed by internal consistency using Cronbach’s alpha. Then, construct validity of the single factor CBI was assessed using Confirmatory Factor Analysis (CFA). Since one factor CBI was not confirmed, construct validity was examined using Exploratory Factor Analysis (EFA). The final number of factors was confirmed using CFA. Results The internal consistency of the instrument was good with Cronbach’s alpha 0.89. Based on EFA, the CBI were loaded on two factors, eigenvalues >1, no item was removed. The emergent factors were named "Communicating respectfully" and "Professional knowledge and skill". These two factors explained 50.197% of the total variance. Then, CFA showed an acceptable fit for the two factors CBI. Conclusion The results showed that the Persian version of the 16-item CBI had adequate validity and reliability. Accordingly, this instrument can be used to study nurses’ caring behaviors.

Abstract Background Given the importance of screening pregnant women’s distress, it was intended to investigate the psychometric properties of the Persian version of the Tilburg Pregnancy Distress Scale (TPDS-P) for screening pregnancy distress. Methods This methodological psychometric study was conducted with participation of 360 pregnant women. The TPDS was translated into Persian. Factor analysis was used to investigate the construct validity. The results of the correlation test between the results of the two questionnaires, Depression Anxiety Stress Scales-21 (DASS-21) and TPDS-P, were used to determine the criterion validity of TPDS-P. Internal consistency of the items was calculated by the Cronbach's alpha coefficient. Stability of the results was examined by test-retest method and Intra-class Correlation Coefficient (ICC) was calculated. Examining the structure of the factors derived from exploratory factor analysis, fitness of the model was done through confirmatory factor analysis. Statistical analysis was done using SPSS software. Results Kaiser-Meyer-Olkin (KMO) was 0.846 (p = 0.001). Sixteen items of TPDS-P accounted for 51.42 percent variances. The TPDS-P exhibited appropriate fitness. There was poor to moderate but significant direct correlation between the subscales of DASS-21 and TPDS-P. Cronbach’s alpha coefficient of the TPDS-P was 0.81 and ICC was 0.70. Conclusions TPDS-P, with appropriate validity and reliability, can be used as a practical scale to evaluate women's distress during pregnancy in Farsi-speaking societies.
