Effects of Type of Instructions on the Characteristics of an Affective Instrument.
Rogers, Bruce G.
The manner in which instructions to respondents influenced the psychometric results of an affective instrument was examined. Undergraduate students enrolled in an educational measurement course were randomly assigned to either immediate response or careful response treatments. A fifteen-item attitude scale was administered to both groups. The immediate reaction group was instructed to rely on their first impressions of the items and were advised not to go back once they had responded to a statement. The careful response group was instructed to be as sincere and accurate as possible in their answers and to feel free to change responses if necessary. For each group, coefficient alpha was computed as an estimate of internal consistency. The t-test and discriminant analysis were used to contrast the two data sets. No item types could be identified to differentiate between the two groups of respondents. In addition, instrument reliability and total scores were not significantly different under either condition of instructions. (Author/JAC)
