The JCWS subtests, in their entirety, display impressive internal consistency and reliability, marked by a split-half coefficient of .98 and a Spearman-Brown prophecy coefficient of .99.
While these findings underscore the JCWS’s potential as a reliable instrument for evaluating verbal abilities, it is crucial to acknowledge the limitations present in this study, such as the small sample size used for assessing internal consistency and concurrent validity across the complete JCWS. The need for further research is evident, aiming to extend the evaluation of the JCWS’s validity and explore its applicability across diverse settings and populations.
This article highlights the JCWS’s promise as an evaluative tool for verbal ability, potentially serving a pivotal role in both academic and clinical spheres, contingent upon further validation and exploration.
