Validity and Reliability of the Clinical Competency Evaluation Instrument for Use among Physiotherapy Students Pilot study
Journal Title: Sultan Qaboos University Medical Journal - Year 2015, Vol 15, Issue 2
Abstract
Objectives: Te aim of this study was to determine the content validity, internal consistency, testretest reliability and inter-rater reliability of the Clinical Competency Evaluation Instrument (CCEVI) in assessing the clinical performance of physiotherapy students. Methods: Tis study was carried out between June and September 2013 at University Kebangsaan Malaysia (UKM), Kuala Lumpur, Malaysia. A panel of 10 experts were identifed to establish content validity by evaluating and rating each of the items used in the CCEVI with regards to their relevance in measuring students’ clinical competency. A total of 50 UKM undergraduate physiotherapy students were assessed throughout their clinical placement to determine the construct validity of these items. Te instrument’s reliability was determined through a cross-sectional study involving a clinical performance assessment of 14 fnal-year undergraduate physiotherapy students. Results: Te content validity index of the entire CCEVI was 0.91, while the proportion of agreement on the content validity indices ranged from 0.83–1.00. Te CCEVI construct validity was established with factor loading of ≥0.6, while internal consistency (Cronbach’s alpha) overall was 0.97. Test-retest reliability of the CCEVI was confrmed with a Pearson’s correlation range of 0.91–0.97 and an intraclass coefcient correlation range of 0.95–0.98. Inter-rater reliability of the CCEVI domains ranged from 0.59 to 0.97 on initial and subsequent assessments. Conclusion: Tis pilot study confrmed the content validity of the CCEVI. It showed high internal consistency, thereby providing evidence that the CCEVI has moderate to excellent inter-rater reliability. However, additional refnement in the wording of the CCEVI items, particularly in the domains of safety and documentation, is recommended to further improve the validity and reliability of the instrument.
