Sets of bipolar scales were constructed for self description
for 13 different traits. Within each trait
four scales, which differed in the relationship between
the trait dimension and the desirability of the
endpoints, were developed. Two scales had either
both desirable or both undesirable endpoints. The
other two scales had one desirable and one undesirable
endpoint but differed from one another in
the direction of the trait dimension. Self-descriptions
were obtained from 606 students on the 13
sets of scales and bipolar marker scales to measure
the dimensions of evaluation, potency, activity, and
familiarity. In addition, each student answered a
true-false social desirability scale. The data were
factor analyzed and rotated to simple structure.
The factors closely reflected the trait dimensions.
There were no factors that could be interpreted as
either a social desirability or evaluation factor. The
correlations of the bipolar scales that had differences
in desirability of the endpoints averaged .12
with the social desirability scale and .13 with the
evaluation marker scale. The correlations between
the scales within each trait set reflected primarily
the trait relationships but seemed to be moderated
by the effects of evaluation or desirability. Scores
were obtained on the sum of the four scales within
each trait dimension. These scores were reasonably
internally consistent and uncorrelated with social
desirability. The potential for this method of personality
assessment is discussed.
