The cross-validity of the filial obligation scale.

The filial obligation scale we developed needed examining cross-validity to make it more precise. In this study, by examining this scale in an area different from the previous study in terms of characteristics (e.g., rural v. urban), we verify its cross-validity. The results showed that three factors extracted from factor analysis precisely reflected Morioka's theory and the correlation coefficients with affiliation and geographic distance that were indicated to be related with filial obligation in the previous studies showed significance. The results of this study support reliability and validity of this scale.
