The comparability of positive and negative items in scales of ethnic prejudice.

"These findings suggest that the use of positive or negative items or a mixture of both is immaterial in the measurement of ethnic prejudice. All-negative item scales do not appear to possess any intrinsic superiority as has been previously assumed. While these reports support the choice of the E scale when desirable for continuity with earlier research, they equally support the use of a mixed scale when an all-negative (or all-positive) scale is regarded as creating problems of rapport."
