Development of communication skill assessment tool (Persian-version) for undergraduates of Rehabilitation Therapy based on Carkhuff's model

Rehabilitation communication skills, its role in treating patients, and therapy evaluation of these skills cannot be measured due to the quality constituents. Therefore, experts and connoisseurs are in search of methods for skills evaluation in order to state various groups of quantitative and comparative skills. The aim of the present research is to design communication skills tools for students in medical rehabilitation based on Carkhuff's Model. The current research is of a descriptive analytical method of correlation type carried out during educational years of 2012-2013 using improbable sampling method and in (easy) access. In order to study content and face validity of primary evaluation forms, Delpha method was used to investigate reliability in evaluation form. Two assessors directly observed thirty students separately and simultaneously and were invited to fill the required form. For inter group correlation of tool reliability evaluation, ICC was applied. In addition, for the determination of correlation coefficient of each domain in comparison with the total score and the correlation of each quadruple domains of Carkhuff's model with each other, Spearman's model of correlation was run. In the second stage, 165 students were evaluated by their professors and the constructive validity was also approved by exploratory factorial analysis. For data analysis, SPSS (version: 18) was used. The content validity of evaluation form was 87.5% and the face validity for total form was 87.25%, and the coefficient of Cronbach's alpha was 0.93. Significant correlation was observed between each domain score and the total score, and the score of each domain and that of the other domains, with the accuracy degree of one percent. The Factorial analysis in the second stage was also specified: from among the four domains of Carkhuff's model, three domains had the required validity. Carkhuff's model of compiled assessment tool was high in content validity, face validity, constructive validity, and reliability and therefore can be used as assessment tool in communication skills in the field of rehabilitation science.
