Validation of the Breastfeeding Experience Scale in a Sample of Iranian Mothers

Objectives. The aim of this study was to validate the breastfeeding experience scale (BES) in a sample of Iranian mothers.Methods. After translation and back translation of the BES, an expert panel evaluated the items by assessing the content validity ratio (CVR) and content validity index (CVI). 347 of mothers visiting health centers completed the Farsi version of the BES in the first month postpartum. Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were performed to indicate the scale constructs. Reliability was assessed by Cronbach's alpha coefficient.Results. CVR and CVI scores for the BES were 0.96 and 0.87, respectively. Cronbach's alpha coefficient for the BES was 0.83. The results of the EFA revealed a new 5-factor model. The results of the CFA for the BES indicated a marginally acceptable fit for the proposed model and acceptable fit for the new model (RMSEA = 0.064, SRMR = 0.064,χ2/df = 2.4, and CFI = 0.95). Mothers who were exclusively breastfeeding at the first month postpartum had less breastfeeding difficulties score (30.3 ± 7.6) than mothers who were on partial breastfeeding (36.7 ± 11.3) (P<0.001).Conclusions. The Farsi version of the BES is a reliable and valid instrument to assess postpartum breastfeeding difficulties in Iranian mothers.

Knowledge Scale

Background: The incidence of dementia is increasing dramatically worldwide. It is important to determine knowledge about the dementia for it’s prevention, early diagnosis, treatment, and care. The psychometric properties of the Turkish version of the Dementia Knowledge Assessment Scale (DKAS-T) were evaluated in this study. Methods: The psychometric study was conducted. A total of 1592 participants were recruited between November 2019 and March 2020. The data were collected using a sociodemographic form and DKAS-T. The language and content validity, exploratory factor analysis (EFA), and confirmatory factor analysis (CFA) were used to assess the validity of the scale. The scale’s reliability was obtained using Cronbach’s alpha coefficient, a paired sample t-test, item-total score correlation, and Hotelling’s T-squared test. Results: The mean age of the sample was 29.38 (±11.50) years; 66.8% (n = 1064) were female, and 54.1% (n = 861) reported their income status as income equal to expenditure. The DKAS-T demonstrated content validity and adequate sensitivity (Kendall W = 0.155, p = 0.093). The scale consisted of seventeen items and was unidimensional, which explained 28.705% of the variance. All the factor loadings were found to be >0.30 in factor analysis. In CFA, all of the fit indexes were >0.95 and root mean square error of approximation (RMSEA) was 0.033. A Cronbach’s alpha value of 0.836 was obtained for the entire scale. It was determined that the scale has invariance according to time (t = −1.362, p = 0.181). Homogeneity of the scale was 3.26%, and there was no absence of reaction bias (Hotelling’s T-squared = 2573.681, p < 0.001). Conclusion: The results demonstrated that the instrument is reliable and generates valid data for the Turkish sample. This scale can be used to determine knowledge about dementia and planning educational interventions in the issue.

Breastfeeding Attitudes

Positive attitudes towards breastfeeding in health professionals/students have been associated with increasing their confidence to provide support and accompaniment to mothers. In Mexico, there is no valid/reliable tool to assess attitudes towards breastfeeding in this population. The Australian Breastfeeding Attitudes (and Knowledge) Questionnaire (ABAQ) measures attitudes in the Australian population. We aimed to adapt and validate the ABAQ in Mexican health students. We included 264 health students (nursing, nutrition, and medicine) from the University of Guadalajara. Bilingual translators carried out the Spanish adaptation with a reverse translation into English. Experts evaluated the content validity. Reliability was evaluated through an internal consistency analysis (Cronbach’s alpha) and construct validity through convergent–divergent validation, item–total correlation, exploratory factor analysis (by principal components), and confirmatory factor analysis. According to the exploratory factor analysis, only one component was identified. Seven items were removed (low correlation between items ≤0.2 and low factor load ≤0.3). The Cronbach’s alpha was 0.78. According to the confirmatory factor analysis, the one-factor solution of the ABAQ-13Mx showed a good model fit (X2 = 98.41, G = 62, p = 0.02, CFI = 0.940, and RMSEA = 0.048). The ABAQ-13Mx is a reliable and valid instrument for evaluating attitudes towards breastfeeding in Mexican health degree students.

Abstract Background One of the main elements that help students in research projects and composing dissertations is the student-supervisor relationship. A valid and reliable tool to measure this seems essential and it is the objective of the present study to validate and assess the psychometric properties of a questionnaire on supervisor-doctoral student interaction (QSDI) in Iran. Methods Before starting the study, a permission from the developer of the tool was secured. Then the tool was forward-backward translated. After preparing the Farsi version of the tool, content validity was confirmed through qualitative and quantitative methods. To examine construct validity, exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were conducted with participation of 218 and 410 MD, MSc, and PhD students of medical sciences, respectively. To check reliability of the tool, correlation coefficient was used. To examine internal consistency of the tool, Cronbach’s alpha was used. Data analyses were done in SPSS (v.25) and LISREL (v.8). Results The EFA and CFA results revealed eight factors and 39 items. The value of R-square for the model was equal to 0.99, which means 99% of changes in the dependent variable (supervisor-student interaction) is attributed to the independent variable (41 items). That is, 99% of the dependent variable changes is due to the independent variables. The main indices of the model based on factor analyses were supported (0.9<), which indicated goodness of fit of the model (χ2/df = 1.76, CFI, NFI, TLI = 0.98 GFI = 0.91, RMSEA = 0.043, R-square = 0.99). The significance level for correlation coefficient was below 0.05. Reliability of the tool was supported based on internal correlation (Cronbach’s alpha) equal to 0.943 for the whole tool and in 0.89–0.97 range for the subscales. Conclusion In general, the results showed that the Farsi version of QSDI (eight factors and 39 items) had acceptable and applicable indices and it can be used as a valid tool in different fields for higher education students of medical sciences.

Abstract: Introduction: Clinical teaching is based on a real work environment, in professional practice settings, such as health services and units, under the supervision of the preceptor. Providing medical teachers with an assessment of their teaching skills is a powerful tool for improving clinical learning for students in training. In this context, the EFFECT (Evaluation and Feedback for Effective Clinical Teaching) questionnaire was developed by Dutch researchers in 2012 for teacher evaluation, being validated based on the literature about medical teaching in the workplace and incorporates the skills of the Canadian competency-based medical curriculum. Objective: To translate and cross-culturally adapt into Brazilian Portuguese and to validate the EFFECT questionnaire for teacher evaluation by Medical students. Method: Cross-cultural adaptation with the following steps: initial translation of the English version, synthesis of translated versions, back-translation, creation of a consensual version in Brazilian Portuguese, with adaptation, review, and analysis of content validity by an expert committee, pre-test with retrospective clarification interview, and reliability analysis by factorial analysis and internal consistency test (Cronbach’s alpha coefficient). Result: In the translation and back-translation stages, the disagreements were related to the use of synonyms and none of the items were modified in terms of their understanding, but in terms of adaptation into the Brazilian context. The evaluation of the expert committee showed the versions maintained the semantic and idiomatic equivalences of the content. Eighty-nine students participated in the pre-test. The internal consistency of the EFFECT questionnaire in Brazilian Portuguese was excellent for all domains, with Cronbach’s alpha coefficient ranging from 0.82 to 0.94. Conclusion: The translated and adapted version of the EFFECT questionnaire into Brazilian Portuguese is equivalent to the original instrument and has evidence of high validity and reliability, being able to constitute a national tool to evaluate the efficiency of clinical medicine teaching.

Relevance. Nowadays the researchers commonly use a limited set of standard procedures and statistical coefficients when develop psychometric instruments and investigate their structure. The routine using of such procedures without taking into account the specific features of the psychometric scales can lead to incomplete or even inadequate results. In this context detailed consideration of the structure of psychometric instruments seems to be important and it may demand various non-standard ways of statistical analysis. Objectives. To conduct detailed analysis of the results of two intelligent subtests at the item level and to assess the sufficiency and adequacy of using standard methods for estimation of reliability and structural validity for these subtests. Methods. We analyze the data collected in intelligence testing of a large sample of respondents (11335 young adults). The respondents passed the KR-3 battery. In this study we examine in detail the structure of the subtests “Syllogisms” and “Analogies”. Specifically, we estimated the reliability of the scales by the Cronbach’s alpha coefficient, and the structure at the item level using the confirmatory factor analysis. Results and conclusions. Estimation of the reliability of the scales by Cronbach’s alpha coefficient showed importance of taking into account the time limitation, which is commonly used in intelligence tests. On the other hand, a detailed analysis of each subtest items made it possible to find out an additional factor which was not originally proposed in the factor structure. This is factor of higher-order abilities of abstract analysis, whilst the subtest originally aimed at estimation of the special abilities. Confirmatory factor analysis showed improvement of fit when this factor was added. The results allow to conclude that the researcher may miss the important properties of scales if not making a detailed analysis of testing procedures and the structure of subtest at the item level, and so may draw incomplete or inadequate conclusions about their psychometric properties

Ethical Climate Questionnaire

Background: An ethical climate has been described as a working climate embracing shared perceptions about morally correct behaviour concerning ethical issues. Various ethical climate questionnaires have been developed and validated for different contexts, but no questionnaire has been found concerning the ethical climate from an inter-professional perspective in a healthcare context. The Swedish Ethical Climate Questionnaire, based on Habermas’ four requirements for a democratic dialogue, attempts to assess and measure the ethical climate at various inter-professional workplaces. This study aimed to present the construction of and to test the psychometric properties of the Swedish Ethical Climate Questionnaire. Method: An expert group of six researchers, skilled in ethics, evaluated the content validity. The questionnaire was tested among 355 healthcare workers at three hospitals in Sweden. A parallel analysis (PA), an exploratory factor analysis and confirmatory factor analysis were performed. Ethical considerations: The participants included in the psychometric analysis were informed about the study, asked to participate in person and informed that they could withdraw at any time without giving any reason. They were also assured of confidentiality in the reporting of the results. Findings: The parallel analysis (PA) recommended one factor as a solution. The initial exploratory factor analysis with a four-factor solution showed low concordance with a four-factor model. Cronbach’s alpha varied from 0.75 to 0.82; however, since two factors only consisted of one item, alpha could not be reported. Cronbach’s alpha for the entire scale showed good homogeneity (α = 0.86). A confirmatory factory analysis was carried out based on the four requirements and showed a goodness-of-fit after deleting two items. After deletion of these items, Cronbach’s alpha was 0.82. Discussion: Based on the exploratory factor analysis, we suggest that the scale should be treated as a one-factor model. The result indicates that the instrument is unidimensional and assesses ethical climate as a whole. Conclusion: After testing the Swedish Ethical Climate Questionnaire, we found support for the validity and reliability of the instrument. We found the 10-item version of Swedish Ethical Climate Questionnaire satisfactory. However, we found no support for measuring different dimensions and, therefore, this instrument should be seen as assessing ethical climate as of whole.

BACKGROUND: Given the increased rate of divorce, it is important to analyse the characteristics of divorce applicants. The theory of planned behaviour (TPB) can provide a suitable framework to predict, explain, and/or change the behaviours. In Iran, no instrument can be found, based on health education models, to investigate divorce petition filing as a behaviour.AIM: This study was conducted to design a questionnaire on withdrawal of divorce petition based on the TPB and estimate its validity and reliability.MATERIAL AND METHODS: A qualitative study was conducted in 27 participants involved in the divorce process using directed content analysis. The face and content validity of 58 items, drawn from the qualitative study, were evaluated by 10 experts. The reliability was estimated using Cronbach’s alpha coefficient. The SPSS version 16 was used to analyse data.RESULTS: Estimates of the face and content validity (quantitative and qualitative), revealed that of the 58 items, 48 were valid based on four of the constructs of the TPB. Cronbach’s alpha coefficient was also derived greater than 0.6.CONCLUSION: The designed questionnaire, whose validity and reliability was confirmed in this study, can be used in similar studies. However, the social and cultural differences and their related effects should be considered.

Background: The importance of salutogenesis, with the focus of what creates health rather than what causes diseases, has been highlighted for a long time. This has been operationalized by Aaron Antonovsky as the Sense of Coherence (SOC-13) scale. The aim of this study was to further examine the psychometric properties of the SOC-13 in India. Methods: The present study was carried out among second-year degree students at three randomly chosen institutions at Mangalore University. Investigators assessed the appropriateness, relevance, comprehensiveness and understandability of the scale. Further, the scale was assessed by five subject experts. The SOC-13 was then pretested by administering it to peers, individuals and a few of the study subjects. Internal consistency was assessed by Cronbach’s alpha and split-half reliability. Test-retest reliability was assessed by administering the instrument to the same study participants after two weeks. Confirmatory factor analysis employing varimax rotation was employed. Results: The SOC-13 revealed a Cronbach’s alpha value of 0.76. Split-half reliability and Guttman split-half reliability were found to be 0.71 and 0.70, respectively. Test-retest reliability was found to be 0.71 ( p < 0.01). Factor analysis revealed a three-factor solution explaining 40.53% of the variation in SOC. Conclusions: SOC-13 was found to be a reliable and valid instrument for measuring SOC in an Indian context. The present study contributes to health promotion in an Indian context, and could be useful even in other developing countries and for further research in India.

Background: Many organizations believe that physician involvement is important in quality and safety of health services, but they did not properly define, measure, and improve it, so because of the importance of the quality of health care and increasing the involvement of physician this study was conducted to evaluate the validity and reliability of a questionnaire on the challenges of physicians' participation in quality improvement programs. Methods: In this cross-sectional study conducted in the hospitals of Mashhad University of Medical Sciences, a researcher-made questionnaire about challenges of physicians' participation in accreditation activities used for data gathering. The content validity ratio index and content validity index were also calculated. To measure the internal consistency of the instrument, the questionnaire was distributed among 14 physicians, Cronbach's alpha coefficient was determined. For stability or reproducibility of the instrument, test - retest and correlation coefficient were calculated. By distributing questionnaires among 14 people those meeting inclusion criteria, the correlation coefficient was measured twice and at intervals of 2 weeks. SPSS 21 software was used for data analysis Results: The initial questionnaire was consisted of 61 items, which were reduced to 38 items after face and content psychometrics. The questionnaire has 12 sub-concepts. Cronbach's alpha coefficient of the questionnaire was 0.83 and the intragroup correlation coefficient in 2 measurements 2 weeks apart was 0.94. Conclusion: This questionnaire is the first and only valid and reliable dedicated tool in the field of challenges of physicians' participation in accreditation activities in Iran, which can measure and prioritize the challenges in each health center and it can be used to improve health care quality services that are performed by doctors.
