The study sought to evaluate the influence of extreme response style on mood state factors isolated. The factors obtained after partialling out response bias from intercorrelations of adjectives were compared with those obtained from the original set. A sample of the 349 high school students were administered a 63-adjective feeling-and-mood inventory. A principal axis analysis of the adjective intercorrelations disclosed seven mood states, all monopolar. After extreme response-bias score was partialled out of the intercorrelations the matrix of partial correlations was analyzed and seven factors were identified. Three of the mood states identified were bipolar and four were monopolar.
