Background: Dental anxiety remains a common problem encountered amongst those who are going to have a dental extraction procedure. Objective: The objective of the current study was to test the validity and reliability of the modified dental anxiety scale for dental extraction procedure (MDAS-DEP). Methods: The current study was conducted by using a cross-sectional survey method on one hundred and thirty-two (69 female; 63 male) participants who were about to go through the dental extraction procedure. A modified version of the MDAS was used in the current study. The questions of the original MDAS were replaced by specific questions about the dental extraction procedure, accompanied by five Likert-type answers. Reliability was measured by referring to the Cronbach’s alpha value whilst construct validity was measured by using Pearson’s correlation. Results: The analysis of the current study showed a Cronbach’s alpha value of 0.822 Whilst the Pearson’s correlation analysis revealed that all questions were proven to be valid, with the highest r value gained by question number 5 (r = 0.817, p < 0.01). Conclusion: The current scale was proven to be valid and reliable to be used as a specific scale to measure dental anxiety due to dental extraction.

ABSTRACT Objective: To validate the construct and test the reliability of the Brazilian version of Hypertension Knowledge-Level Scale. Methods: Methodological research with 220 participants in a primary health care unit from Curitiba, Paraná. The data were collected with a social demographic questionnaire and the Brazilian version of the scale. The construct validity and reliability were assessed using Cronbach’s Alpha, Pearson’s Correlation and Analysis of Variance. The discriminant validity was verified comparing groups of people with hypertension and without, using T test. Results: Cronbach’s Alpha was 0.74. The groups comparison showed that people with hypertension had better results (p<0,001). Pearson’s Correlation showed that the questions measure different aspects of the same construct, justifying its organization in subdimensions. Conclusion: The Brazilian version of Hypertension Knowledge-Level Scale is a reliable instrument, which had its construct and criterion validated to measure knowledge about hypertension among Brazilian people. It can help health professionals with planning educative actions.

BACKGROUND: Almost 25%of workers in the European Union suffer from back pain, and 23%complain of muscle pain. Sixty-two percent of workers carry out repetitive operations with their hands or arms, 46%work in painful or tired positions and 35%carry or handle loads. OBJECTIVE: This study aimed to translate, culturally adapt and validate the Italian version of the Cornell Musculoskeletal Discomfort Questionnaire (CMDQ-I). METHODS: Translation and cultural adaptation procedures followed international guidelines. Participants were recruited from among the personnel components of the Italian Air Force, who were between 18 and 65 years old. Cronbach’s alpha and the intraclass correlation coefficient (ICC) were calculated to assess internal consistency and stability, respectively. The CDMQ-I was administered together with the Visual Analogic Scale (VAS), and the validity was evaluated using Pearson’s correlation coefficient. RESULTS: All CDMQ-I items were either identical or similar in meaning to the original version’s items. The scale was administered twice with a retest after seven to 10 days to 66 participants. Cronbach’s alpha was higher than 0.761, and the ICC ranged between 0.737 and 0.952. Pearson’s correlation coefficient showed positive and significant correlations (p >  0.01). CONCLUSIONS: The study produced an Italian version of the CMDQ with good reliability and validity. This scale is a useful tool to investigate the frequency and intensity of musculoskeletal disorders in various categories of workers.

Abstract Background Anxiety is one of the most prevalent mental health disorders among mothers during the postpartum period, which can lead to maternal and infant physical and psychological consequences. The Postpartum Specific Anxiety Scale (PSAS) predicts unique variance in postnatal outcomes over and above general anxiety tools. It has never been used in Iran and its validity and reliability have not been assessed either. Therefore, the present study aimed to translate and investigate the psychometric properties of the PSAS-IR. Methods 510 women, from six weeks to six months postpartum, were selected through random sampling in 2020. After forward and back-translation, the face validity, content validity, and construct validity of PSAS (through confirmatory factor analysis) were examined. The reliability of the scale was assessed using both internal consistency (Cronbach’s alpha) and test-retest stability methods. Results CVI and CVR values of the PSAS tool were 0.89 and 0.88, respectively. The good fit indices confirmed the validity of four-factor structure. Cronbach’s alpha coefficient and Intra Correlation Coefficient (ICC) equaled 0.93 and 0.92, respectively. Conclusion The Persian version of PSAS is a valid and reliable four-factor scale, it will improve the measurement of postpartum anxiety in an Iranian setting. This will improve the measurement of postpartum anxiety in an Iranian setting.

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.

This paper is part of a study which addresses the reliability of Foreign Language Anxiety Scale (FLCAS) in Malay version.  Researchers find that the reliability of an instrument is closely associated with its validity and an instrument cannot be valid unless it is reliable. However, the reliability of an instrument does not depend on its validity. Therefore, this paper investigates the reliability of the instrument called FLCAS in Malay version.  FLCAS is widely used in collecting data relating to language anxiety and perhaps the most reliable and comprehensive tool in language anxiety.  This paper objectively measures the reliability of FLCAS by using Cronbach’s Alpha, the most widely used objective measure of reliability.  The sampled population involved 302 respondents from the government secondary schools in Putrajaya Federal Territory, Malaysia.  The items had been translated into the Malay language and back translated into English.  Results show that the internal consistency of Crobanch’s Alpha 0.90.  It can be concluded that FLCAS in Malay version is an appropriate instrument to measure the levels of language anxiety among the Malaysian secondary school students who learn English as a second language.

Background Evidence-based medicine (EBM) is a widely accepted scientific advancement in clinical settings that helps achieve better, safer, and more cost-effective healthcare. However, presently, validated instruments to evaluate healthcare professionals’ attitude and practices toward implementing EBM are not widely available. Therefore, the present study aimed to determine the validity and reliability of a newly developed knowledge, attitude, and practice (KAP) questionnaire on EBM for use among healthcare professionals. Methods The Noor Evidence-Based Medicine Questionnaire was tested among physicians in a government hospital between July and August 2018. Exploratory factor analysis and internal consistency reliability-based Cronbach’s alpha statistic were conducted. Results The questionnaire was distributed among 94 physicians, and 90 responded (response rate of 95.7%). The initial number of items in the KAP domains of the Noor Evidence-Based Medicine Questionnaire were 15, 17, and 13, respectively; however, two items in the practice domain with communalities <0.25 and factor loadings <0.4 were removed. The factor structure accounted for 52.33%, 66.29%, and 55.39% of data variance in the KAP domains, respectively. Cronbach’s alpha values were 0.81, 0.81, and 0.84 for KAP domains, respectively, indicating high reliability. Conclusions This questionnaire can be used to evaluate the knowledge, attitudes, and behaviour of healthcare professionals toward EBM. Future testing of this questionnaire among other medical personnel groups will help expand the scope of this tool.

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).

Heart Failure Questionnaire

The Minnesota Living with Heart Failure Questionnaire (MLHFQ) has been developed to measure health-related quality of life (HRQoL) status of Heart Failure (HF) patients. The aim of this study was to translate MLHFQ into the Persian version and assess the validity and reliability of the translated version. We used a forward-backward procedure for translation. In a cross-sectional study, 105 HF patients and 50 healthy subjects were selected to assess the reliability and construct validity of the instrument. The face and content validity were used to assess the questionnaire validity. Validity was examined on the HF patients group, using the Persian version of the Short form-36 health survey (SF-36) Questionnaire. In order to assess the questionnaire’s reliability, the Intraclass correlation coefficient (ICC) and Cronbach’s alpha were calculated. Test-retest reliability was examined by re-administering the MLHFQ after 2 weeks. Test-retest results demonstrated that the Persian version has excellent reliability (ICC for all 2 domains were higher than 0.91, P≤0.000). Internal consistency for Physical domain (PD), emotional domain (ED) and total scores using Cronbach’s alpha were 0.90, 0.84 and 0.92, respectively. ICC for PD, ED and total scores were 0.95, 0.94, and 0.97, respectively. Good and very good Pearson's Correlation Coefficient was seen between MLHFQ and SF-36 (r= -0.47 to -0.775, P≤0.000 for PD; r= -0.47 to -0.65, P≤0.000 for ED). The Persian version of the MLHFQ had satisfactory reliability and validity for assessing HRQoL status of Iranian HF patients. © 2019 Tehran University of Medical Sciences. All rights reserved.

Abstract: Introduction: The humanities are associated with the improvement of medical students’ personal qualities. To date, there are no research instruments that quantify the exposure of medical students have to the humanities. Hence, the availability of a questionnaire with such characteristics in Brazilian Portuguese sets a precedent for the planning and implementation of educational strategies and policies addressing this topic. Objective: to translate and transculturally adapt the “HUMANITIES SCORE (LIFE EXPERIENCES + ATTITUDES) questionnaire, determine its validity and reliability, as well as identify the type of exposure to the humanities of the assessed population. Method: The original version of the questionnaire, written in English, was translated according to what is recommended by the specialized literature, with the addition of some activities in the humanities field, as per the original authors’ suggestion. The translated instrument underwent a pre-test with 31 medical students for semantic validation, followed by the application of its final version to 258 students. The exploratory and the confirmatory factorial analyses were applied to assess the instrument with its internal consistency was checked with Cronbach’s Alpha coefficient. Result: The final questionnaire was administered to the students to verify their type of exposure to the humanities. After the statistical tests were carried out, the final version of the instrument, named “Escala de Exposição às Humanidades” (EEH), included 17 items with Likert-scale responses with five options each, and obtained a Cronbach’s alpha of 0.689. The mean score of the students’ exposure was 1.72 ± 0.37, being influenced by the period at medical school, the number of volunteer social activity experiences, the participation in religious groups, the practice of meditation, and the involvement in political activities. Variables such as female gender, engagement in previous actions related to the humanities before starting medical school and in religious ceremonies positively influenced the students’ opinion about the importance of the humanities for the medical curriculum. Conclusion: The EEH demonstrated reliability in its structure and content, allowing correlations between the students’ exposure to humanities and their opinion about the importance of human sciences in the medical curriculum. It constitutes the first instrument that aims at measuring the humanities exposure rate in Brazil; however, further studies must be carried out, to better validate the instrument.
