A three dimensional test for White's effectance motive.
A scale was developed based on Robert W. White's construct of effectance motivation. Effectance was conceptualized as involving three dimensions--Effect on Self, Effect on Objects, and Effect on People. It was found that reliabilities for the three subscales were good. Validity was determined using three methods: criterion groups, multitrait-multimethod matrix, and convergent and discriminant validity. Validity was supported under all three methods.
