Validity and reliability of the Arabic version of the "Personal Wellbeing Index-Adults" on adults with hearing impairment.

ABSTRACT: Background: The Personal Wellbeing Index-Adults (PWI-A) is the most widely used instrumentfor measuring subjective-quality of life (QoL). The current study seeks to investigate the constructvalidity and reliability of the Arabic version of the PWI-A on adults with bilateral hearingimpairment by comparing the single-factor solution with the two-factor solution. Methods: A cross-sectional study was conducted at the Audio-Vestibular Medicine Unit of Alexandria University from July-2017 to January-2018. A total of 205 adults were interviewed tomeasure the subjective-QoL using the PWI-A instrument. Internal consistency was determinedusing both Cronbach's alpha and composite reliability (CR). Validity was assessed by constructvalidity, including ordinal regression, ordinal exploratory factor analysis (OEFA), and ordinalconfirmatory factor analysis (OCFA). Results: The first four items of the PWI-A which are: satisfaction with living standard, health,achievements, and relationships were the most important indicators of subjective-wellbeing(Part r2 0.0547, 0.0324, 0.0361, and 0.0225, respectively). OEFA suggested that the two-factormodel contributes better than the single-factor model. OCFA validated this suggested solution;(two-factor: RMSEA=0.084 (90% CI=0.01-0.14); CFI=0.964; AIC=52.64; single-factor: RMSEA=0.119 (90% CI=0.07-0.17); CFI=0.922; AIC=62.77). Good internal consistency wasalso presented (two-factor: Cronbach's alpha=0.719, 0.693; single-factor: Cronbach's alpha =0.750). Conclusion: The Arabic version of the PWI-A is a multidimensional scale that consists of twodimensions: the first is related to subjective-QoL, and the second is related to satisfaction withthe community. Thus, it is recommended to use the short version of the PWI-A with only fouritems to measure subjective-QoL, as it achieved sufficient reliability and construct validity.

Project description:BackgroundThe International Physical Actvity Questionnaire (IPAQ) is a validated tool for physical activity assessment used in many countries however no Arabic version of the long-form of this questionnaire exists to this date. Hence, the aim of this study was to cross-culturally adapt and validate an Arabic version of the long International Physical Activity Questionnaire (AIPAQ) equivalent to the French version (F-IPAQ) in a Lebanese population.MethodsThe guidelines for cross-cultural adaptation provided by the World Health Organization and the International Physical Activity Questionnaire committee were followed. One hundred fifty-nine students and staff members from Saint Joseph University of Beirut were randomly recruited to participate in the study. Items of the A-IPAQ were compared to those from the F-IPAQ for concurrent validity using Spearman's correlation coefficient. Content validity of the questionnaire was assessed using factor analysis for the A-IPAQ's items. The physical activity indicators derived from the A-IPAQ were compared with the body mass index (BMI) of the participants for construct validity. The instrument was also evaluated for internal consistency reliability using Cronbach's alpha and Intraclass Correlation Coefficient (ICC). Finally, thirty-one participants were asked to complete the A-IPAQ on two occasions three weeks apart to examine its test-retest reliability. Bland-Altman analyses were performed to evaluate the extent of agreement between the two versions of the questionnaire and its repeated administrations.ResultsA high correlation was observed between answers of the F-IPAQ and those of the A-IPAQ, with Spearman's correlation coefficients ranging from 0.91 to 1.00 (p < 0.05). Bland-Altman analysis showed a high level of agreement between the two versions with all values scattered around the mean for total physical activity (mean difference = 5.3 min/week, 95% limits of agreement = -145.2 to 155.8). Negative correlations were observed between MET values and BMI, independent of age, gender or university campus. The A-IPAQ showed a high internal consistency reliability with Cronbach's alpha ranging from 0.769-1.00 (p < 0.001) and intraclass correlation coefficient (ICC) ranging from 0.625-0.999 (p < 0.001), except for a moderate agreement with the moderate garden/yard activity (alpha = 0.682; ICC = 0.518; p < 0.001). The A-IPAQ had moderate-to-good test-retest reliability for most of its items (ICC ranging from 0.66-0.96; p < 0.001) and the Bland-Altman analysis showed a satisfactory agreement between the two administrations of the A-IPAQ for total physical activity (mean difference = 99.8 min/week, 95% limits of agreement = -1105.3; 1304.9) and total vigorous and moderate physical activity (mean difference = -29.7 min/week, 95% limits of agreement = -777.6; 718.2).ConclusionThe modified Arabic version of the IPAQ showed acceptable validity and reliability for the assessment of physical activity among Lebanese adults. More studies are necessary in the future to assess its validity compared to a gold-standard criterion measure.

Project description:BackgroundThe psychometric properties of self-administered instruments for measuring patient satisfaction with removable dentures should be tested before inviting patients to express their opinions. This study aimed to evaluate the validity and reliability of new instruments in the Arabic language that measure patient satisfaction with all types of removable dentures.MethodsA three-step methodology was used to translate and test the instruments. In step one, the instruments were translated from tested German instruments to develop the pilot questionnaires. In step two, the face validity of the pilot questionnaires was tested through three rounds of interviews. There were 15, 13, and 15 participants per round, respectively. At the end of every round, the results of the interviews were discussed with an expert panel. The expert panel confirmed the form and the type of questionnaires' adjustments before a new round of interviews began. At the end of step two, the final form of the questionnaires was reached. In step three, 235 questionnaires were distributed to 133 participants to estimate the construct validity of the upper jaw and the lower jaw questionnaires. After one week, the participants were asked to complete the questionnaires again. A total of 102 questionnaires were returned and used to assess the instruments' reliability. Factor analysis was used to assess the construct validity. The intraclass correlation coefficient and Cronbach's alpha were used to estimate the reliability and suitability of the items in the indexes.ResultsThe result of step one was two pilot questionnaires. The pilot questionnaires were adjusted in step two. At the end of step two, the questionnaires proved to have good face validity. Factor analyses in step three revealed that only one factor could be retained. The one-factor model explained 60.95% and 63.06 of the total variance of the upper jaw and lower jaw questionnaires, respectively. The items in every questionnaire shared the same cluster and could be summed to form an upper jaw index and lower jaw index that reflected patient satisfaction with removable dentures. Cronbach's alpha values indicated excellent internal consistency and reliability for the upper jaw questionnaire (α = 0.91) and the lower jaw questionnaire (α = 0.92). Intraclass correlation coefficient values ranged from 0.72 to 0.95, which can be considered "moderate" to "excellent".ConclusionsThe Arabic version of questionnaires and indexes assessing patient satisfaction with upper and lower removable dentures are reliable and valid self-administered instruments.

Project description:BackgroundOswestry Disability Index (ODI) is broadly used in clinical and research settings for assessing the disability level in patients with lumbar radiculopathy but it has not been translated into Urdu language according to the pre-established translation guidelines as well as the validity and reliability of ODI Urdu version has not been tested yet. The aim of this study was to translate ODI in native Urdu language (ODI-U) according to recommended guidelines and to measure its psychometric properties in Urdu speaking patients suffering from lumber radiculopathy.MethodsOut of 108 participants, 54 were healthy (who filled ODI-U) and 54 were patients of lumber radiculopathy. The patients were administered through ODI-U, visual analogue scales for disability (VAS disability), pain intensity (VAS pain) and SF-36 at baseline and after 3 days. Reliability was investigated through test-retest method, internal consistency, standard error of measurement (SEM) and smallest detectable change (SDC). ODI-U was assessed for exploratory factor analysis, construct (convergent and discriminative) validity and content validity. Alpha level < 0.05 was considered statistically significant and psychometric standards were evaluated contrary to priori hypothesis.ResultsODI-U revealed excellent test-retest reliability for total score (ICC2,1 = 0.95) and for all item (ICC2,1 = 0.72-0.98). Cronbach's alpha of 0.89 showed excellent internal consistency and moderate correlation between ODI-U total score and each item through spearman's correlation coefficient (r = 0.51-0.76). One factor structure was created, explaining 52.5% variance. There was no floor and ceiling effect of total ODI-U score. Content validity was assessed through conducting interviews with patients and incorporating expert's opinions. The discriminative validity was measured by independent sample t-test, where significant difference between healthy and patients (P < 0.001) was observed. The convergent validity was evaluated through Pearson's correlation showing moderate positive correlation of ODI-U with VAS pain (r = 0.49) and VAS disability (r = 0.51) but moderate negative correlation with all SF-36 domains (r = - 0.43to - 0.63).ConclusionODI-U showed adequate psychometric properties. ODI-U was found to be a reliable and a valid tool to measure the level of disability in Urdu-speaking patients with lumber radiculopathy.

Project description:INTRODUCTION:Early Onset Scoliosis (EOS) is a complex pathology that covers a variety of etiologies, with onset before the age of 10 years. Surgical treatment of EOS should have the objectives of fulfilling maximum pulmonary function, spine length, with minimal hospitalizations, complications, and family burden. Radiographic parameters are an important standard in assessing treatment outcomes. However, the Early Onset Scoliosis Questionnaire-24 (EOSQ-24) was developed to measure the wider dimensions of outcomes involving the quality of life of patients and caregivers post-treatment. The aim of this study was to evaluate the validity and reliability of culturally adapted Arabic version of the EOSQ-24. METHODS:Translation and cross-cultural adaptation, based on published guidelines, were performed on the original English EOSQ-24 by a committee. The Arabic version of EOSQ-24 was applied to the caregivers of all 58 EOS patients who were treated surgically after signing a consent form. Reliability was assessed using Cronbach's ? and item-total statistics for the whole questionnaire initially and for the each domain separately. Data quality was assessed by mean, median, percentage of missing data, ceiling and floor effects. Discriminative validity was examined using non parametric tests. RESULTS:The response for all items was excellent with only 1.7% (0-1) of responses missing. The floor effect ranged from 0% to 36.2% of patients and the ceiling effect ranged from 0 to 46.6%. Cronbach's ? test reliability was found excellent (0.919), as was the internal consistency of all domains, with Cronbach ? ranging from 0.903 to 0.918. Corrected item-total correlations were good for all domains (>0.3). Only one item (Question 21) showed low corrected item-total correlations (r = 0.222). However, Cronbach's ? did not increase significantly when this item was deleted (0.920). CONCLUSION:The first adapted Arabic version of EOSQ-24 is found to have good validity and reliability, and it can be used to assess children in Arab societies with EOS.
