“…For direct measurement of physical performance, in addition to the specific methods and tests that are required, for instance VO 2max , food uptake, and heart rate, subjects must perform a specific task. Indirect methods, on the other hand, employ data collection procedures such as subjects filling out self-reporting questionnaires (7, 9, 10). …”

Validity and Reliability of the Persian Version of Baecke Habitual Physical Activity Questionnaire in Healthy Subjects

BackgroundBaecke Habitual Physical Activity Questionnaire (BHPAQ) has widely been employed in clinical and laboratorial studies as a tool for measuring subjects' physical activities. But, the reliability and validity of this questionnaire have not been investigated among Persian speakers.ObjectivesTherefore, the aim of the current study was examining the reliability and validity of the Persian version of the BHPAQ in healthy Persian adults.Materials and MethodsAfter following the process of forward-backward translation, 32 subjects were invited to fill out the Persian version of the questionnaire in two independent sessions (3 - 7 days after the first session) in order to determine the reliability index. Also, the validity of the questionnaire was assessed through concurrent validity by 126 subjects (66 males and 60 females) answering both the Baecke and the International Physical Activity Questionnaire (IPAQ).ResultsAn acceptable level of intraclass correlation coefficient (ICC of work score = 0.95, sport score = 0.93, and leisure score = 0.77) was achieved for the Persian Baecke questionnaire. Correlations between Persian Baecke and IPAQ with and without the score for sitting position were found to be 0.19 and 0.36, respectively.ConclusionsThe Persian version of the BHPAQ is a reliable and valid instrument that can be used to measure the level of habitual functional activities in Persian-speaking subjects.

“…In addition, CFA of the Greek LEFS also supported the one-factor structure of the scale (Stasi et al, 2013). In contrast, two-factor structure was reported for the Persian (Negahban et al, 2014) and German (Naal et al, 2015) versions of the LEFS using EFA methods. No information on items loading pattern was provided for the Persian version while the two-factor structure for the German version was established specifically in patients with total hip or knee replacement with changing loading patterns overtime.…”

“…The results of these factorial analyses formed the basis for the structural hypothesis tested in the current study. Two studies reported a two-factor structure for the LEFS on the basis of EFA (Naal et al, 2015;Negahban et al, 2014). While the authors of the Persian version of LEFS suggested a two-factor structure, they did not provide details on this two-factor structure and the pattern of items loading on these two factors (Negahban et al, 2014).…”

The aim of this study was to examine the factorial structure of the Arabic version of the Lower Extremity Functional Scale (LEFS-Ar) using a confirmatory factor analysis. The study was designed as a cross-sectional study in which individuals with lower extremity musculoskeletal disorders were recruited. During the testing session, participants completed the LEFS-Ar in addition to general information form and anthropometric measurements. A hypothesized one-factor structure underlying the 20 items of the LEFS-Ar was examined using a confirmatory factor analysis. The fit of the observed data to the hypothesized factorial structure was examined using multiple fit statistics including χ2, Tucker-Lewis index (TLI), comparative-fit index (CFI), and the root mean square error of approximation (RMSEA). A total of 160 patients with lower extremity dysfunctions participated in this study. The fit statistics showed the following: χ2 goodness fit statistic=654.390 (d.f.=170, P<0.001), TLI=0.754, CFI=0.78, and RMSEA=0.134 (90% CI=0.123-0.145). These fit statistics indicate that the data do fit the one-factor structure proposed in this study. Examination of standardized residuals and modification indices pointed to areas of misfit within the model. The findings of the current study do not support the hypothesized one-factor structure of the LEFS-Ar and suggest that modifications are needed to the LEFS-Ar to yield a unidimensional measure of lower extremity function (i.e. activity limitation due to lower extremity dysfunction).
