The Manifest Anxiety (MA), Extraversion (E), Repression-Sensitization (R-S), and 13 other personality scales were given to 226 Ss. The purpose was to determine the extent to which MA scores are attributable to the influence of extraversion and to explore the degree to which the R-S scale assesses attributes similar to those measured by the MA and E scales. From the results of a factor analysis of the 16 variables the following conclusions were drawn: Scores on the MA and R-S scales are almost totally independent of E. The MA and R-S scales are practically identical in psychological meaning; scores on both these scales are largely determined by two bipolar, orthogonal traitsdefensiveness and emotionality.
