A study of the validity and reliability of the questionnaire entitled “physicians' approach to and disclosure of medical errors and the related ethical issues

Medical errors are among the major challenges that threaten patients’ health worldwide. The aim of this study was to design a valid and reliable questionnaire to investigate the status of medical error disclosure by physicians. A preliminary questionnaire was developed based on the extracted results from 37 interviews with specialists. To test the validity of the questionnaire, 20 medical practitioners and medical ethics authorities were asked to evaluate the relevance and clarity of each item. To measure the instrument’s reliability (the intra-class correlation coefficient and Cronbach’s alpha), a test-retest study was conducted on 20 randomly selected physicians twice with a 2-week interval. Statistical analyses were performed using SPSS software version 20. The overall relevance and clarity of the instrument, with an average approach, were measured at 97.22 and 94.03 percent respectively. The Cronbach’s alpha, which presents the internal consistency was satisfactory (0.70 - 0.79) for various domains of the questionnaire. The range of intra-class correlation coefficients for the items in all domains of the questionnaire was 0.76 to 1.00. Regarding the validity and reliability of the questionnaire, it can be an appropriate instrument in the assessment and monitoring of the status of medical error disclosure by physicians.

The validity analysis of the scale for the data collected was performed with exploratory factor analysis and item-total correlation tests, while the property of reliability was determined using the Cronbach’s alpha internal consistency coefficient and the stability test was carried out by determining the relationship between two applications conducted at an interval of the five weeks. The scale, which is called the “Scale for Determining the Civic-Mindedness Levels of Individuals” is a five-step Likert-type scale and consists of 27 items that can be collected under three factors. The factor names are “Openness to Criticism/Development”, “Participation/Activeness” and “Lack of Prejudice/Flexibility”. The KMO value of the scale was 0.956; and the Bartlett Test values were x2=11001.719; sd=351; p<0.000. Items in the scale accounted for 56.619% of the total variance. As a result of the confirmatory factor analysis, the χ2 value was 808.07 and the degree of freedom was 321. Χ2/df is 2.51. The fit indices of the scale were determined as RMSEA=0.067; S-RMR=0.049; NFI=0.97. The item-total corrected correlation coefficients of the items in the scale varied between 0.40 and 0.703 (p<.01). The reliability coefficient of the scale was Cronbach’s alpha at 0.954 and the stability coefficients of the items were between 0.496 and 0.674 (p<,01).

Abstract Context: Measurement of patient-centred outcomes enables clinicians to focus on patient and family priorities and enables quality of palliative care to be assessed.Objectives: This study aimed to evaluate the validity and reliability of the English and translated Chinese IPOS among advanced cancer patients in Singapore.Methods: IPOS was forward and backward translated from English into Chinese. Structural validity was assessed by confirmatory factor analysis; known-group validity by comparing inpatients and community patients; construct validity by correlating IPOS with Edmonton Symptom Assessment System-revised (ESAS-r) and Functional Assessment of Cancer Therapy–General (FACT-G); internal consistency by Cronbach’s alpha; inter-rater reliability between patient and staff responses; test-retest reliability of patient responses between two timepoints.Results: 111 English-responding and 109 Chinese-responding patients participated. The three-factor structure (Physical Symptoms, Emotional Symptoms and Communication and Practical Issues) was confirmed with Comparative Fit Index and Tucker-Lewis-Index > 0.9 and Root Mean Square Error of Approximation < 0.08. Inpatients scored higher than outpatients as hypothesised. Construct validity (Pearson’s correlation coefficient, r≥|0.608|) was shown between the related subscales of IPOS and FACT-G and ESAS-r. Internal consistency was confirmed for total and subscale scores (Cronbach's alpha ≥ 0.84), except for the Communication and Practical Issues subscale (Cronbach’s alpha = 0.29–0.65). Inter-rater reliability (Intra-class correlation coefficient [ICC] ≤ 0.43) between patient and staff responses was insufficient. Test-retest reliability was confirmed with Intra-class correlation coefficient ICC = 0.80 (English) and 0.88 (Chinese) for IPOS Total.Conclusion: IPOS in English and Chinese showed good validity, good internal consistency, and good test-retest reliability, except for the Communication and Practical Issues subscale. There was poor inter-rater reliability between patients and staff.

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.

Background:An accurate physical fitness survey could be useful in research and clinical care.Purpose:To estimate the validity and reliability of a Self-Reported Fitness (SRFit) survey; an instrument that estimates muscular fitness, flexibility, cardiovascular endurance, BMI, and body composition (BC) in adults ≥ 40 years of age.Methods:201 participants completed the SF-36 Physical Function Subscale, International Physical Activity Questionnaire (IPAQ), Older Adults’ Desire for Physical Competence Scale (Rejeski), the SRFit survey, and the Rikli and Jones Senior Fitness Test. BC, height and weight were measured. SRFit survey items described BC, BMI, and Senior Fitness Test movements. Correlations between the Senior Fitness Test and the SRFit survey assessed concurrent validity. Cronbach’s Alpha measured internal consistency within each SRFit domain. SRFit domain scores were compared with SF-36, IPAQ, and Rejeski survey scores to assess construct validity. Intraclass correlations evaluated test-retest reliability.Results:Correlations between SRFit and the Senior Fitness Test domains ranged from 0.35 to 0.79. Cronbach’s Alpha scores were .75 to .85. Correlations between SRFit and other survey scores were –0.23 to 0.72 and in the expected direction. Intraclass correlation coefficients were 0.79 to 0.93. All P-values were 0.001.Conclusion:Initial evaluation supports the SRFit survey’s validity and reliability.

Study Results

Introduction: Rabies is a highly fatal disease that is mostly caused by a dog bite. The Dog Bite Prevention KAP scale is a 30-item scale that is designed to measure children’s level of safety knowledge on dog’s behaviour, precautionary behaviour around dogs, perceived vulnerability towards dogs and help-seeking behaviour following a dog bite. Therefore, this study aimed to determine the test-retest reliability and validity of outcome measures. Methods: This questionnaire was administered to samples of school student aged from 13 years to 14 years at a secondary school located in Bau District, Sarawak. They were purposively selected for a baseline interview (Time 1) and a ten-day follow-up (Time 2). This study was conducted within four months, which were from 10 April to 31 August 2018. Descriptive analysis, content analysis, Cronbach’s alpha, intra-class correlation and exploratory factor analysis were performed in this study. Results: A total of 64 boys and 114 girls were involved in the study, whereby 79.2%, 10.1%, 7.9%, 2.2% and 0.6% of them were of Bidayuh ethnic, Chinese, Iban, Malays and other ethnic, respectively. The Cronbach's alpha was 0.796. The test-retest intra-class correlation was adequate, with 0.84 for perceived vulnerability towards dogs and 0.81 for precautionary behaviour around dogs. Principal components analysis with varimax rotation resulted in two factors, which explained 39% of the variance (perceived vulnerability towards dogs) and 49% of the variance (precautionary behaviour around dogs). Conclusion: The questionnaire is a valid and reliable tool for a dog-bite prevention survey.

Abstract: Introduction: Many disease-specific questionnaires, which analyze patients’ functional status, quality of life or the progression of the disease, have been validated in Hungarian. The low back pain (LBP) patients’ knowledge about their problem has not been measured by an officially validated Hungarian tool. Aim: The aim of our study was to translate and validate the Low Back Pain Knowledge Questionnaire (LKQ) and to assess its validity and reliability. Method: We used the translation-back translation method as the first step. Then we used a synthesis of the back translations reviewed by independent translators. We enrolled 218 people in our study: 101 of them were chronic LBP patients and 73 acute LBP patients. For the validation process, we used the Roland–Morris Disability Index to compare our questionnaire. We calculated Cronbach’s alpha values and correlation coefficients. Results: The Hungarian version of LKQ correlated well with the Roland–Morris Index and it proved to be a valid questionnaire (correlation coefficient: –0.393; Cronbach’s alpha value 0.894). Conclusion: We found the Hungarian version of LKQ a valid and reliable tool to measure patients’ knowledge about LBP. We recommend future studies should apply bigger and more homogenous populations to assess LBP disease-specific knowledge in this country. Orv Hetil. 2019; 160(42): 1663–1672.

Simple Definition

The Psychology of Religion has had a tradition measuring things that are seemingly difficult to measure, such as one’s level of religiosity or spirituality – concepts that are polysemantic, so do not have a simple definition. In doing so, researchers have developed scales to measure such constructs. This trend in Psychology of Religion research will continue as researchers start to conduct studies in non-Western Educated Industrialized Rich Democratic (WEIRD) populations, as they will require new scales that are appropriate for the way that these populations conceptualize religiosity and spirituality. Scale construction takes multiple steps, which most researchers are well-acquainted with. One important step is to demonstrate both validity and reliability. In the Psychology of Religion, an overwhelming majority of researchers use Cronbach’s alpha to estimate scale reliability. However, alpha has multiple preconditions that can easily be violated in psychology research that are rarely tested for, let alone adjusted for. Much like with using parametric statistical analyses when parametric assumptions are violated, this approach may be leading to inaccurate reporting. This article will discuss; (1) whether alpha should be used at all in Psychology of Religion research and, if so, when it is appropriate; (2) introduce another estimate of scale reliability, Omega, and show how and it might be calculated; (3) provide examples of how these techniques might be taught to students studying Psychology of Religion at undergraduate and higher levels. In doing so, I hope to move the entire field of Psychology of Religion forward in terms of methodological rigor.

AbstractThe lack of a Swedish patient-reported outcome instrument for eosinophilic esophagitis (EoE) has limited the assessment of the disease. The aims of the study were to translate and validate the Eosinophilic Esophagitis Activity Index (EEsAI) to Swedish and to assess the symptom severity of patients with EoE compared to a nondysphagia control group. The EEsAI was translated and adapted to a Swedish cultural context (S-EEsAI) based on international guidelines. The S-EEsAI was validated using adult Swedish patients with EoE (n = 97) and an age- and sex-matched nondysphagia control group (n = 97). All participants completed the S-EEsAI, the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Oesophageal Module 18 (EORTC QLQ-OES18), and supplementary questions regarding feasibility and demographics. Reliability and validity of the S-EEsAI were evaluated by Cronbach’s alpha and Spearman correlation coefficients between the domains of the S-EEsAI and the EORTC QLQ-OES18. A test–retest analysis of 29 patients was evaluated through intraclass correlation coefficients. The S-EEsAI had sufficient reliability with Cronbach’s alpha values of 0.83 and 0.85 for the “visual dysphagia question” and the “avoidance, modification and slow eating score” domains, respectively. The test–retest reliability was sufficient, with good to excellent intraclass correlation coefficients (0.60–0.89). The S-EEsAI domains showed moderate correlation to 6/10 EORTC QLQ-OES18 domains, indicating adequate validity. The patient S-EEsAI results differed significantly from those of the nondysphagia controls (p < 0.001). The S-EEsAI appears to be a valid and reliable instrument for monitoring adult patients with EoE in Sweden.
