Aims: To demonstrate the reliability and validity of the modified four-square step test (mFSST) and the step test (ST) in community-dwelling older adults. Methods: Fifty older adults were recruited. The test-retest reliability of the mFSST and ST was evaluated with one-hour-interval. The mFSST and ST was compared with Timed up and Go Test (TUG) and Five Times Sit to Stand Test (FTST) to demonstrate concurrent validity. Results: The mean age of the participants was 72.0 ± 5.7 years. The test-retest reliability of mFSST and ST was excellent (ICC = 0.971 and 0.938, respectively). In concurrent validity analysis, the mFSST was strongly correlated with TUG and FTST (r 1 =0.755,r 2 =0.575,p < 0.001). Both the ST (right) and ST (left) were highly correlated with TUG and FTST (r= −0.527 to −0.578, p < 0.001). In addition, the ST (right) and ST (left) were highly correlated with FTST (r 1 = −0.533,r 2 = −0.527,p < 0.001). Conclusions: mFSST and ST was proven to be valid and reliable in older adults.

Background To our knowledge, no other studies investigated the internal consistency of the Edinburgh Visual Gait Score (EVGS). The aim of our study was to determine the reliability and construct validity of the EVGS in children with cerebral palsy (CP). Results A total of fifty children with CP were enrolled in the study. Participants were evaluated with Gross Motor Function Classification System (GMFCS), Wisconsin Gait Scale (WGS), Gillette Functional Assessment Questionnaire (Gillette FAQ), Timed Up and Go Test (TUG), and EVGS (Rater-A and Rater-B). Slow-motion video analysis was used for the visual gait analysis. The inter-rater reliability, internal consistency, and construct validity of the EVGS were analyzed. The intraclass correlation coefficient (ICC) of the EVGS total score was 0.947 (CI: 0.90–0.97). Inter-rater reliability was excellent (ICC>0.80). The Cronbach’s alpha value was 0.936, within the acceptable range (0.70<α<0.95). In addition, the standard error of measurement (SEM95) and minimal detectable change (MDC95) scores of EVGS were 1.72 and 4.78, respectively. The correlation values of EVGS (Rater-A) and GMFCS, TUG, GFAQ, and WGS were 0.494, 0.661, −0.663, and 0.611, respectively. On the other hand, the correlation values of EVGS (Rater-B) and GMFCS, TUG, GFAQ, and WGS were 0.492, 0.664, −0.714, and 0.757, respectively. Except for comparison with GMFC, EVGS was highly valid in all other correlational analyzes (r>0.50). EVGS had moderate validity with GMFCS for both raters. Conclusion The EVGS was reliable and valid. Internal consistency of the EVGS is high, indicating a consistent structure to assess gait in children with CP.

The aim of the study was to translate and adapt the Self-Regulatory Fatigue Scale (SRF-18) into Turkish and also demonstrate its reliability and validity in young adults.Design and Methods: A total of 181 participants completed SRF-18, Life Orientation Test-Revised (LOT-R), Brief Self-Control Scale (BSCS), and Multidimensional Fatigue Inventory (MFI). One week later 30 participants refilled SRF-18.Findings: The internal consistency of SRF-18 was good (α = 0.710). The intraclass correlation coefficient value of the SRF-18 total score was 0.608. SRF-18 was strongly related to MFI and LOT-R (r 1 = −0.632, r 2 = 0.557, p < 0.001). Besides, there was a moderate relationship between SRF-18 and BSCS (r = 0.439, p < 0.001).
