Validation of an Italian version of the functional index for hand osteoarthritis (FIHOA)

Abstract

Objectives To translate the functional index for hand osteoarthritis (FIHOA) into Italian and to evaluate its reliability and validity in Italian patients with hand osteoarthritis (HOA).

Methods The original French FIHOA was translated into Italian according to the guidelines for cross-cultural adaptation and then administered to 72 outpatients with HOA, together with the visual analogue scale of pain (VAS), the Health Assessment Questionnaire (HAQ) and the Short Form Health Survey (SF-36). Test–retest reliability was verified by having all patients fill out the Italian version of FIHOA again 1 week later. Item–item analysis was performed. The Wilcoxon signed-rank test and Spearman’s rank correlation coefficient were calculated to compare test and retest responses and to evaluate the degree of correlation. Internal consistency reliability was evaluated by Cronbach’s alpha coefficient, and internal structure validity was appraised through factor analysis, also taking a varimax rotation into consideration. Construct validity was assessed by correlating FIHOA with other measures of functional impairment and pain using Spearman’s rank correlation coefficient.

Results Internal consistency was high (Cronbach’s α = 0.87). Test–retest reliability showed a Spearman’s rho of 0.942 (p < 0.001). A significant correlation (p < 0.001) between FIHOA, VAS and HAQ and a significant negative correlation between FIHOA and SF-36 subscales were observed. FIHOA was confirmed to be a non-unidimensional scale, but in addition to the total score of the index, three subtotals of item scores were considered to provide better evaluations of finger functionality (items 3, 6, 8 and 10), wrist functionality (items 2 and 7) and hand strength (items 4 and 5) in single individuals.

Conclusions The Italian version of FIHOA is a reliable and valid instrument for evaluating functional disability in Italian-speaking HOA patients.     

Impaired response inhibition scale for alcoholism (IRISA): development and psychometric properties of a new scale for abstinence-oriented treatment of alcoholism

BACKGROUND: Impaired inhibition of conditioned response plays a significant role in relapse in addictive behaviors. Although patients and their relatives frequently discuss this behavioral deficit when seeking treatment, no instrument is yet available to measure its severity. The aim of this study was to develop the Impaired Response Inhibition Scale for Alcoholism (IRISA) to assess this impairment in alcohol-dependent patients. METHODS: A preliminary version of the IRISA was administered to a group of 151 patients under treatment at our center. Exploratory factor analysis was conducted using principal component analysis. The validity and reliability of the IRISA were examined. RESULTS: Factor analysis and item refinement led to a definitive 16-item IRISA that accounted for 61.6% of the total variance and revealed Impaired Response Inhibition as a single factor. Psychometric properties of this version of the IRISA scale showed excellent internal consistency (Cronbach's alpha: 0.96), good test-retest reliability (intraclass correlation coefficient: 0.81), and satisfactory convergent, discriminant, and predictive validity. The IRISA has a good correlation with alcohol craving, the severity of alcoholism, and alcohol consumption during the recovery process. CONCLUSIONS: Our initial results with the IRISA suggest that it is a reliable and valid tool to measure impairment in response inhibition to drinking behavior. The IRISA assesses a potentially important aspect of treatment process and outcome.     

Translation and Psychometric Evaluation of the Chinese Version of Functional Digestive Disorders Quality of Life Questionnaire

Background

Few useful patient-reported outcomes scales for functional dyspepsia exist in China.

Aims

The purpose of this work was to translate and cross-culturally adapt the Functional Digestive Disorders Quality of Life Questionnaire (FDDQL) from the English version to Chinese (in Mandarin).

Methods

The following steps were performed: forward translations, synthesis of the translations, backward translations, pre-testing and field testing of FDDQL. Reliability, validity, responsiveness, confirmatory factor analysis, item response theory and differential item functioning of the scale were analyzed.

Results

A total of 300 functional dyspepsia patients and 100 healthy people were included. The total Cronbach’s alpha was 0.932, and split-half reliability coefficient was 0.823 with all test–retest coefficients greater than 0.9 except Coping With Disease domain. In construct validity analysis, every item correlated higher with its own domain than others. The comparative fit index of FDDQL was 0.902 and root mean square error of approximation was 0.076. Functional dyspepsia patients and healthy people had significant differences in all domains. After treatment, all domains had significant improvements except diet. Item response theory analysis showed the Person separation index of 0.920 and the threshold estimator of items was normally distributed with a mean of 0 and standard deviation of 1.27. The residuals of each item were between ?2.5 and 2.5, without statistical significance. Differential item functioning analysis found that items had neither uniform nor non-uniform differential item functioning in different genders and age groups.

Conclusions

The Chinese version of FDDQL has good psychometric properties and is suitable for measuring the health status of Chinese patients with functional dyspepsia.     

Validation of the Quality-of-Life Questionnaire of the European Foundation for Osteoporosis (QUALEFFO-26) in Korean population

We aimed to evaluate the reliability and validity of the adapted Korean version of the Quality-of-Life Questionnaire of the European Foundation for Osteoporosis (QUALEFFO-26). Translation/retranslation of the English version of QUALEFFO was conducted, and all steps of the cross-cultural adaptation process were performed. The Korean version of the visual analog scale measure of pain, QUALEFFO-26 and the previously validated Short Form-36 (SF-36) were mailed to 162 consecutive patients with osteoporosis. Factor analysis and reliability assessment by kappa statistics of agreement for each item, the intraclass correlation coefficient and Cronbach’s α were conducted. Construct validity was also evaluated by comparing the responses of QUALEFFO-26 with the responses of SF-36 using Pearson’s correlation coefficient. Factor analysis extracted 3 factors. All items had a kappa statistics of agreement greater than 0.6. The QUALEFFO-26 showed good test/retest reliability (QUALEFFO-26: 0.8271). Internal consistency of Cronbach’s α was found to be very good (QUALEFFO-26: 0.873). The Korean version of QUALEFFO-26 showed good significant correlation with SF-36 total score and with single SF-36 domains scores. The adapted Korean version of the QUALEFFO-26 was successfully translated and showed acceptable measurement properties and, as such, is considered suitable for outcome assessments in the Korean-speaking patients with osteoporosis.

Attitudes toward the elderly among the health care providers: reliability and validity of Turkish version of the UCLA Geriatrics Attitudes (UCLA-GA) scale

The population of above 65 years of age is increasing fast in societies, as the life expectancy is increasing and it leads to high demands for health care service. Health care service for the elderly should be provided by trained team in this field. Success of health care service to be rendered is related to knowledge, skill and attitudes of team members in different profession group (doctor, nurse, social worker, psychologist, etc.) about health of elderly. The aim of this study is to establish the Turkish validity and reliability of 14-question UCLA-GA scale, validity and reliability of which was proven and used the most frequently among the scales that assess attitudes of health care providers toward elderly. A total 256 people, 150 of them were post-graduates, 106 of them were pre-graduates were involved in the study at Ege University, medical faculty between the dates of December 2010 and February 2011. Majority of the participants (63.67%) were women and in the age group of 18-29 (58.3%). The ratio of the ones undergoing geriatric education is 38.2%. It was found out that the Kaiser-Meyer-Olkin (KMO) sampling adequacy test presented high correlation among the items in both single adult households of 14 items of the scale was 0.72. Cronbach alpha value of the scale was found as 0.67 and satisfying. As a result of examination with Tukey's test of additivity, it was seen that items of the scale have additive quality (F=85.25, p<0.0001). When we calculated the correlation of each item with total score, it was found that correlation coefficient varied between 0.32 and 0.68. Test-retest reliability was defined by use of Pearson correlation analysis. It was determined that test-retest consistency of correlation scale between two measurements was r=0.51. As a result of test-retest application, the correlation between the first and second application scores of each item was analyzed to determine the internal consistency of each item of the scale. Based on this analysis it was found as p<0.01 between r=0.22 and 0.65. As a conclusion, Turkish validity and reliability of UCLA-GA scale was demonstrated in this study. Since Turkish version of UCLA-GA scale is short and clear, it is recommended to use it for determining attitudes of health care providers toward elderly in geriatrics.

Development and validation of a Functional Dyspepsia-Related Quality of Life (FD-QOL) scale in South Korea

Background: Quality of life (QOL) in patients with functional dyspepsia in South Korea has never been studied, mostly due to the lack of a psychometrically validated disease‐specific instrument for measuring the QOL. The aim of the present study was to develop and validate a QOL scale for patients with functional dyspepsia. Methods: A Functional Dyspepsia‐Related QOL (FD‐QOL) scale was developed and validated as follows: item generation, pilot test, and psychometric test. Patients with functional dyspepsia (n = 220) were recruited from seven university hospitals. The participants were asked to complete the preliminary item‐generated FD‐QOL, the Short Form‐36 (SF‐36), and the Index of Dyspepsia Symptoms‐Korean (IDS‐K). The data were analyzed using factor analysis, correlation, anova , and Cronbach’s alpha. Results: Twenty‐three items were generated based upon content validity. Factor analysis extracted a four‐factor solution, and two items were deleted because they were not loaded significantly on any factor. The FD‐QOL was correlated with the SF‐36 subscales, of which scores were differentiated according to the levels of dyspepsia symptoms. Cronbach’s alpha of the FD‐QOL was 0.94. Conclusions: The FD‐QOL scale is a rapid and easily applicable instrument with excellent psychometric properties of content, factorial, convergent, and known‐groups validity, and internal consistency reliability in Korean patients with functional dyspepsia.
