A Training-Model Scale’s Validity and Reliability Coefficients: Expert Evaluation in Indonesian Professional Psychology Programs

Abstract

Very little information has been available on training models in professional psychology programs in Indonesia,  despite  the Indonesian National  Accreditation Body recommending that scientist-practitioner models  be applied in the  education of  psychologists. By contrast, research abounds on such training models in Western countries. This discrepancy raises  the importance of developing a measurement tool appropriate for assessing training models in Indonesian  professional psychology programs. This article describes the process of testing the validity and reliability of  such a training model  measuring tool in the Indonesian context. The  a uth ors  used the expert evaluation method and the Aiken formula to  calculate a coefficient of content validity and item’s internal consistency reliability. This process formed a training model  scale comprising 77 items with satisfactory validity and reliability indexes for  measuring Indonesian professional psychology program training models .
