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.

Nowadays, it is common for people to look for health care information on the internet. The eHealth Literacy Scale (eHEALS) is commonly used to measure eHealth literacy. As of the publication of this study, the Indonesian version for eHEALS has not been published even though eHealth literacy is necessary, especially in the current COVID-19 pandemic. We aimed to evaluate the validity and reliability of the Indonesian version of eHEALS (I-eHEALS). A total of 100 respondents in East Java were involved in this cross-sectional study. Pearson-product moment correlation method and construct validity were used to validate the results. The reliability was determined based on the Cronbach’s alpha internal consistency measurement and intraclass correlation coefficient (ICC). The Pearson correlation analysis results are significantly higher ( r > 0.254, p < 0.01) compared to the critical value table. Single factors accounting for 57.66% variance in the scales exhibit a unidimensional latent structure. The internal consistency between items is excellent as shown by the Cronbach’s alpha coefficient (0.91). The ICC analysis shows an acceptable result (0.552, p < 0.01). The I-eHEALS is valid and reliable to be used for evaluating the eHealth literacy of the Indonesian population.

Introduction: St. George’s Respiratory Questionnaire (SGRQ) is a measuring tool to assess the quality of life of people with chronic obstructive pulmonary disease or various respiratory disorders. This study aimed to assess whether The Indonesian version of SGRQ was valid and reliable for subjects with chronic obstructive pulmonary disease (COPD). Methods: The Indonesian version of SGRQ was analyzed using a correlation test between SGRQ and sixminute walk distance (6 MWD) for validity. The reliability test was done using the test re-test reliability test by Spearman’s rank correlation, and Cronbach’s alpha for internal consistency. Results: Twenty-two patients eligible COPD patients were included in this study. There is a correlation between SGRQ’s component and 6MWD on activity (r= 0.49), impact (r= -0.58) and total SGRQ (r=-0.56). The SGRQ re-measurement test shows a strong correlation on the symptom (r = 0.76), activity (r = 0.58), impact (r = 0.51), total (r=0.58) and Wilcoxon test result shows there were no significantdifferences among subscales except total value p = 0.049. High internal Cronbach’s alpha consistency was approximately 0.73 to 0.86. Conclusion: The Activities and Impacts of Indonesian version of SGRQ component provides a picture of the validity to functional capacity.

Abstract Background Population aging is an important phenomenon for many countries worldwide. Considering the growing trend of aging population in Iran, it is very important to consider beliefs and perceptions of old people about aging. The Aging Perception Questionnaire (APQ) is one of the most common instruments that used to measure aging comprehension. The present study was a methodological inquiry that aimed to examine validity and reliability of the Persian version of the Aging Perception Questionnaire (APQ). Methods Forward-backward procedure was used for translation. Content validity and face validity were evaluated qualitatively. In order to evaluate construct validity a cross section study was conducted and both exploratory and confirmatory factor analyses were performed. In order to determine reliability, internal consistency (the Cronbach’s alpha) and stability (Intraclass Correlation Coefficient -ICC) were estimated. Results A total of 500 elderly people attending the community centers in Tehran, Iran were entered in other study and completed the Persian version of the questionnaire. Most elderly were female (52.8%).The mean age of participants was 68.33 (SD ± 6.10) years. The results obtained from exploratory factor analysis showed a four-factors solution (consequences negative, emotional representation, control positive and consequences positive) that jointly explained 52.8% of the total variance observed. In addition the confirmatory factory analysis showed a good fit for the data. Finally, the Cronbach’s alpha coefficient of 0.83 ranging from 0.80 to 0.87 was obtained for the whole scale and the subscales. The ICC value of 0.96 ranging from 0.90 to 0.98 was found for the whole scale and the subscales. Conclusion The results indicated that the Persian version of APQ is valid and can be used to measure aging perception in Iran.

Abstract Purpose To develop an Arabic version of the CPQ8–10 and test its validity and reliability for use among Arabic-speaking children. Methods The 25-item professionally translated questionnaire included two global rating questions across four domains, which was assessed through a pilot study on 20 participants who were not included in the main study. Children (n = 175) aged 8–10 years were consecutively recruited: group I (n = 120) included pediatric dental patients, group II (n = 25) included children with orofacial clefts, and group III (n = 30) included orthodontic patients. Construct (convergent and discriminant) validity, internal consistency, and test–retest reliability were assessed using Spearman’s rank correlation coefficients, Cronbach’s alpha coefficient, and intraclass correlation coefficient, respectively. All children were clinically examined; 66 children completed the questionnaire a second time. A cross-sectional study design was employed. Results CPQ8–10 scores and global ratings were positively correlated. CPQ8–10 scores were highest in group II, followed by groups I and III, respectively. CPQ8–10 scores were significantly higher in children affected with caries or malocclusion compared to unaffected children. Cronbach’s alpha was 0.95 and the intraclass correlation coefficient was 0.97. Conclusions The Arabic CPQ8–10 was valid and reliable; therefore, it can be utilized with Arabic-speaking children in this age group.

Background: Although bigorexia symptoms are rapidly increasing, it is mostly an underrecognized condition in Turkish male bodybuilders. There are no validated screening tools to identify the symptoms. Objective: The purpose of this study is to evaluate the validity of the Turkish version of the MDDI and the BIG towards the diagnosis of bigorexia and to provide health care professionals with early screening tools. Methods: One hundred twenty male bodybuilders, fifty-eight professional bodybuilders and sixtytwo recreational bodybuilders, all of whom matched the research criteria, were included in this study. MDDI and BIG forms were filled by the bodybuilders, along with an “Individual Characteristic Information Form”, a “Nutrition-related Information Form”, and a “Bodybuilding-related Information Form”. To evaluate the construct validity, factor analysis was conducted and resulted in a threefactor construct. Results: The factor-loading values ranged from 0.542- 0.827. Calculations of Cronbach’s alpha for the MDDI sum (α = 0.657) revealed a good internal consistency. The MDDI, BIG O, and BIG S intraclass correlation coefficients (ICC) were found to be 0.840, 0.908, and 0.879, respectively. As a result, MDDI had acceptable reliability and that of BIG O and BIG S was excellent. Discussion: Turkish MDDI, BIG-O and BIG-S forms proved to be valid and reliable scales and were adequate for determining the symptoms of bigorexia in male bodybuilders. Using these forms, there was a statistically significant relationship between bigorexia and eating disorders, which were significantly positively correlated. Conclusion: Our results support the feasibility of using the MDDI, the BIG-O, and the BIG-S forms to determine symptoms of bigorexia in Turkish population. Further studies are needed to confirm if this result can be generalized to female bodybuilders.
