JOB-RELATEDNESS OF A POSTTRAINING JOB KNOWLEDGE CRITERION USE TO ASSESS VALIDITY AND TEST FAIRNESS

Significant job-relatedness was found for a posttraining job knowledge test criterion using an application of Lawshe's content validity method. The aide test was used as a criterion to assess the predictive validity of a vocabulary test and a civil service test with samples of black ( N = 43) and white ( N = 62) psychiatric aides. Significant validities were found on both tests, but a vocabulary test proved to be the better predictor of the criterion in both samples. The obtained validities were discussed in terms of differential validity, test fairness, and sample size. This study demonstrated that a content validity method could be applied to criteria as well as selection tests. It was concluded that content validity methods may be able to help solve the problem of criterion relevance in validation research by providing quantitative evidence of the job-relatedness of criteria.     

The Influence of Cultural Individualism-Collectivism,Self Construals,and Individual Values on Communication Styles Across Cultures

Individualism-collectivism has a direct effect on communication styles and an indirect effect that is mediated through self construals and values. It was hypothesized that cultural individualism-collectivism, self construals, and values would have separate effects on individuals’use of low- and high-context communication styles. As predicted, the results of this study suggest that independent self construals and individualistic values mediate the influence of cultural individualism-collectivism on the use of low-context communication, and interdependent self construals and collectivistic values mediate the influence of cultural individualism-collectivism on the use of high-context communication. The patterns for cultural individualism-collectivism were not as clear-cut. The findings suggest that individual level factors (i.e., self construals and values) are better predictors of low- and high-context communication styles across cultures than cultural individualism-collectivism.
