Five validity studies of scales in the Study of Imagery are reported. Multistage Bonferroni procedures are used to evaluate significance of results. Scales of superego strength and id derivatives both correlate positively with neuroticism as measured by the Eysenck Personality Inventory. The scale of ego strength correlates positively with a measure indicating aspects of behavioral self-control. The scale measuring sense of identity correlates positively with measures of adaptive ego strength and of behavioral self-control, and negatively with a measure of behavioral conflict and one measure of toughmindedness.
