Traditional treatment approach for disordered articulation of sounds: evaluating clinical skills of Speech Language Pathology students by Direct Observation of Procedural Skills

Abstract

Background and Objectives: One of the common disorders in Speech Language Pathology (SLP) is speech sound disorder. To increase students’ competence and objectively evaluate their clinical skills, we used the Direct Observation of Procedural Skills (DOPS) test in a clinical setting and examined its validity and reliability Methods: This research is a non-interventional descriptive study. Twenty students who participated in this study were selected by the census method. Traditional treatment approach skill for speech sound disorder was selected. Then an evaluation checklist of DOPS was prepared. After obtaining the consent of students and professors, they entered the study. Two professors observed the work of all student during the procedure on a real patient. Results were recorded in a checklist, and feedback was given to the students about their strengths and weaknesses. Results: The content validity index of the DOPS test was more than 0.8, and its content validity ratio was more than 0.62. The correlation coefficients of questions indicate the optimal internal structure of the test and its structural validity. The results showed that the test questions were related to the predetermined subject. Results confirmed high face validity. The obtained Cronbach α coefficient (0.865) confirmed DOPS reliability. There was a significant inter-rater correlation coefficient (0.901) between evaluators (P<0.001). Conclusion: According to the study, the use of DOPS for objective assessment of clinical skill has validity and reliability. This test can be used to evaluate the clinical work of SLP students, provide feedback, identify their strengths and weaknesses, and improve them.
