The Persian version of IdFAI is a reliable and valid tool to identify patients with functional ankle instability which have a history of ankle sprain. Its original three-factor structure was replicated in this study. Implications for Rehabilitation The Persian version of the Identification of Functional Ankle Instability (IdFAI) questionnaire is a reliable and valid instrument in order to identify Iranian patients with functional ankle instability in both clinical practice and research. The Persian IdFAI questionnaire may be considered as a standardized clinical instrument that can be used to classify degree of ankle instability in Iranian Persian-speaking people with a history of lateral ankle sprain. People with a history of ankle sprain can be assessed using IdFAI questionnaire before and after rehabilitative interventions in an attempt to determine any change in their degree of ankle instability over time.
Background: Ankle Instability Instrument (AII) is a questionnaire for determination of ankle stability status. The aim of this study is to cross-culturally translate and investigate the reliability and validity of AII in a sample of Persian-speaking Iranians, suffering from ankle sprain.
Methods: One hundred twenty persons with a history of ankle sprain were recruited in the study. All participants completed the Persian version of Ankle Instability Instrument, Cumberland Ankle Instability Tool (CAIT), Foot and Ankle Ability Measure (FAAM) and Foot and Ankle Outcome Score (FAOS) at the baseline. Out of them, 60 randomly selected subjects completed the questionnaires once more, one week later. Face validity, Test–retest reliability, internal consistency, standard error of measurement, minimal metric detectable change, spearman’s correlation coefficient and confirmatory factor analysis of AII measured. We used Lisrel v 8.80 software with significant level of p<0.05.
Results: Persian version of AII is clear and unambiguous and its qualitative face validity was confirmed in the pilot study on the 20 subjects with a lateral ankle sprain. The interclass correlation coefficient, Cronbach’s alpha, standard error of measurement and minimal metric detectable change were 0.93, 0.87, 0.81 and 2.25 (95% confidence interval, 0.85-0.96). The Spearman correlations coefficients between AII, and CAIT, FAAM and FAOS measures were 0.91, 0.71 and 0.69 respectively. The original three factor structure of AII was replicated based on the confirmatory factor analysis. Which showed an adequate fit of the model to the data and goodness-of-various fit indices.
Conclusion: The Ankle Instability Instrument Persian Version (AII-PV) is a reliable and valid measure for assessing the ankle stability status.
Introduction:The present study aimed to investigate validity and reliability of Persian Dimensions of Mastery Questionnaire (DMQ18) in children with cerebral palsy.Material and Methods:The original version was carried out through back translation into Persian, and then the construct validity was assessed by confirmatory factor analysis; and reliability was evaluated through Cronbach’s alpha (n=230). Intra-class correlation coefficient (ICC) was used for test retest reliability (n=32).Results:230 parents (155 (67.4%) mothers and 75 (32.6%) fathers) of children and adolescents with CP with an average age of 126.99±24.59 months participated in the present research. Non-questions excluded from the confirmatory factor analysis, and thus all questions remained. Internal consistency reliability and total score were acceptable in all domains (higher than 0.70) except for negative reactions, sadness/shame (Cronbach’s alpha of 0.414). Intra-class correlation coefficient of all domains and total score were significant (p<0.001).Conclusion:DMQ18 (parental report) was valid and reliable for children with cerebral palsy. It also provided valuable information about different aspects of motivation in CP children according to their parents’ opinion, and thus it can be used in clinical interventions.
