Abstract
The controversy with regard to using reverse or negatively worded survey stems has been around for several decades; it is a practice of questionable utility intended to guard against acquiescence or response set behaviors. A 2 × 3 design in which item stem direction and item response pattern direction were crossed was used to determine effects on internal consistency reliability as measured by Cronbach’s alpha. The condition having the highest alpha was when all directly worded stems were used with bidirectional response options. Alpha was higher and accounted for at least 10%, and in one case 20%, higher internal consistency as compared with any of the three conditions in which negatively worded stems were used. This would indicate that the use of all directly worded stems and half of the response options going in one direction and half going in the other direction may be a better way of guarding against acquiescence and response set behaviors than the use of items with negatively worded stems.
