Psychometric and edumetric properties of the Turkish version of the assessment of physiotherapy practice

BackgroundClinical education is a crucial process in which students learn how to use theoretical knowledge in clinical settings. However, there is no standardized assessment tool routinely used to evaluate the clinical performance of physiotherapy students in Turkey. This study aimed to examine the psychometric (validity and reliability) and edumetric (acceptability, feasibility, and educational impact) properties of the Turkish version of the Assessment of Physiotherapy Practices (APP-T).MethodsThis methodological study included 7 clinical educators and 174 4th-grade physiotherapy students at three universities in Turkey. Students were assessed with the APP-T on completion of 4-week clinical placements. The construct validity was examined using the exploratory factor analysis. The internal consistency was determined using Cronbach's alpha-coefficient. The test-retest and inter-rater reliability were evaluated with the intra-class correlation coefficient (ICC). For the measurement error of the APP-T, standard error of measurement (SEM) and minimum detectable change (MDC) values were calculated. After the administration of the APP-T was completed, clinical educators were requested to provide feedback on the acceptability, applicability, and educational impact of the APP-T.ResultsExploratory factor analysis demonstrated the 20 items of the APP-T represent a single dominant dimension explaining 76.28% of the variance. Excellent test-retest and inter-rater reliability was detected by ICC = 0.94 and ICC = 0.77, respectively, and good internal consistency was detected by Cronbach's alpha = 0.935. The MDC90 values for test-retest and inter-rater reliability were 3.11 and 6.86, respectively. Clinical educators provided generally positive feedback on the acceptability, feasibility, and educational impact of the APP-T.ConclusionsThe current findings provided evidence for universities and clinical educators that the APP-T has sufficient psychometric and educational properties for evaluating the clinical performance of physiotherapy students in Turkey.
