Effects of Response Style on the Polarity and Validity of Two-Dimensional Mood Models

摘要

Unipolar and bipolar two-dimensional models have been proposed to represent mood. This study showed that both models can be derived from the same data depending on whether a response style adjustment is employed. The unipolar and bipolar models defined the same factor space in the sense that mood items occupied the same relative positions in factor space under either model. Both models were equally sensitive to group differences in mood in comparisons between military basic training platoons and between successful and unsuccessful military recruits. Also, each model was as effective as a six-dimensional model for describing these group differences. The findings extend previous evidence that the relative locations of mood items in mood space is an empirical consistency which pro vides a suitable starting point for mood theories. The choice of a unipolar or bipolar frame of reference to express this consistency may be unimportant, but additional research is needed to confirm this conclusion. (Author)
