The purposes of this study were: 1) to determine the measurement dimensions assayed by the EPIC Self-Assessment Scales; 2) to provide information necessary to'determine whether revision of the EPIC Self-Assessment Scales would be desirable, and if so, what items need revision or deletion to obtain optimum dimensional structure; and 3) to provide information relevant to possible further research using the EPIC Self-Assessment Scales. On the basis of the results, four dominant and two subsidiary factors were concluded to be the measurement dimensions assayed by the EPIC Scales. Those were identified as Self-Assurance, Physical Appearance/Physical Shape, Emotional Lability, and Verbal Competence; subsidiary factors were Social/Interpersonal Attitude and Social Behavior/Sociability. It was also concluded that revision of the Scales be undertaken, deleting the 29 bipolar scale items which did not exhibit loadings of .500 or higher on any of the six factors. It was recommended that the revised Scales include additional bipolar scale items taken from the semantic differential literature, and that the instructions to subjects be revised. Further research to establish the reliability and validity of the revised instrument was also recommended.
