Validity and interrater/intrarater reliability of the Turkish version of the postural assessment scale for stroke patients (PASS-Turk)

ABSTRACTBackground: There is no Turkish version of the Postural Assessment Scale for Stroke patients (PASS).Objectives: To translate and make the cross-cultural adaptation of the PASS into the Turkish language and evaluate the reliability and validity of the Turkish version (PASS-Turk).Methods: Sixty patients with stroke who had survived the three-week acute period were included in the study. The first researcher applied the scale to the participants twice with 5-day intervals. The second researcher applied the scale once at the same time with the first researcher. The reliability of PASS-Turk and its subsections was evaluated using Cronbach’s alpha coefficient. In addition, item-total correlation and test-retest reliability were calculated. The interobserver agreement was assessed using the intraclass correlation coefficient. The construct validity of PASS-Turk was assessed using Pearson’s product-moment correlation and principal component analyses. The Berg Balance Scale (BBS) and motor subscale of the ...
