Abstract:
The Holyoake Codependency Index is a 13-item self-report measure of three aspects of codependency: External Focus, Self-sacrifice, and a sense of being overwhelmed by another person's problematic behavior (termed Reactivity). Previous studies have supported internal validity and the internal consistency and construct validity of the subscales. The present scores for 59 students indicate full scale test-retest reliability of .88 and for subscales (.76 to .82) over a 3-wk. interval.
