This paper describes the development of a videotape measure of interpersonal competence (ICI), and reports the results of a study of the ICI's construct validity. The ICI is based on the videotape presentation of scenes that depict subordinates talking to a superior in a business setting. Examinees' replies are rated for effectiveness and examinees' judgments are rated for accuracy. The ICI and a battery of other measures devised to permit a multitrait-multimethod analysis were administered to college students, and factor analyzed. Fine factors were identified. The ICI Accuracy score seems to be tapping general ability to some extent whereas what the ICI Effectiveness score is assessing cannot be determined at all.
