Evidence for Construct Validities of Maruno-Kato Discussion Inventory.
Tomida, Eiji; Maruno, Shunichi; Kato, Kazuo
Maruno-Kato Discussion Inventory (MKDI) is an inventory which consists of self-rating scales measuring discussion skills and related personality traits. Previously, we demonstrated that the MKDI has adequate qualities as psychometric tests. However, to show the effectiveness or validity of the inventory further, we need to demonstrate how well self-ratings on the MKDI can predict students' actual performance in discussion situations. The purpose of this research is to show construct validity of the inventory. For the purpose, first, 43 college student participants were instructed to complete a short version of the MKDI. Second, after one week, all the participants were divided into 10 groups and ask to solve an ill-defined task collaboratively through discussion. All discussions were videotaped and transcribed. In analysis, we observed all discussions and counted individuals verbal behaviors related to components in the MKDI. Then, we calculated the correlation coefficients between the frequencies of relevant verbal behaviors and self-rating scores from MKDI. As a result, we found that the correlations were approximately in line with our expectations. We have concluded that the data is evidence that MKDI scores can predict different aspects of students' performances in actual discussion. (Author)
