PSSS Patellofemoral Pain Severity Scale in Patients with Patellofemoral Pain Syndrome
Description
Patellofemoral Pain Severity Scale in Patients with Patellofemoral Pain Syndrome Reliability and Validity of the Turkish version of the Patellofemoral Pain Severity Scale in Patients with Patellofemoral Pain Syndrome Abstract Purpose: It was planned to investigate the Turkish validity and reliability of the Patellofemoral Pain Severity Scale (PFPS) and to ensure its adaptation to the Turkish language. Materials and methods: A pilot study was conducted with 10 academic physiotherapists and 10 patients to test content validity. 123 patients underwent PPPS test-retest at 24-48 hour intervals. Construct validity, correlations of PPPS with other scales Timed Up and Go Test (TUG), Stair Climbing and Descending Test (SCD), Anterior Knee Pain Scale (AKPS), Tegner Activity Scale (TAS), Lysholm Knee Scoring Scale (LDSS), Knee Outcome Survey Activities of Daily Living Scale (KOS-ADL) were evaluated. Results: The content validity index value of the scale was 0.95. The overall internal consistency (Cronbach α: 0.88) was high. Item-total correlations of the scale were between 0.51 (PSSS 9) and 0.71 (PSSS 4). In the evaluation of the convergent validity of the PSSS, it was found that there was a positive correlation between the PSSS and TUG and SCD, and a negative correlation between the PSSS, TAS, LDSS and KOS-ADL (p=0.000). Conclusions: In this study, it was determined that the PSSS scale had good internal consistency, test-retest validity and adequate construct validity when compared with the KOS-ADL, LDSS and ACPS. These findings suggest that the scale is a reliable and valid measurement tool for native Turkish-speaking patients with PFPS. Key words: Patellofemoral pain syndrome, pain, function; outcome measures; reliability; validity
