Performance Quality Rating Scale for Somatosensation After Stroke Version 3: Reliability, Feasibility.

Abstract

The Performance Quality Rating Scale for Somatosensation after Stroke (PQRS-SS) guides observation of survivors of stroke performing client-selected occupations, using common operational definitions. We aimed to determine the inter- and intra-rater reliability, standard error of measurement, and feasibility (via interviews and thematic analysis) of the PQRS-SS version 3. Videos of 22 survivors of stroke with somatosensory impairment completing 38 client-selected occupations on two occasions (76 clips) were viewed by four clinicians twice, 6 weeks apart (PQRS-SS version 3). Intraclass correlation coefficients (ICC), standard error of measurement (SEM), and interview data are reported. For PQRS-SS version 3, inter-rater reliability was moderate to excellent (ICC_2,1 = 0.71, ICC_2,4 = 0.91) and intra-rater reliability was good (ICC_3,1 = 0.76-0.87). Clinician raters reported the PQRS-SS version 3 was easy to use. The PQRS-SS version 3 is ready for use by trained, experienced clinicians and is ready for ongoing psychometric testing.
