This study assessed the factor structure, internal consistency, and concurrent validity of a revised instrument, the Composite Codependency Scale (CCS), a 19-item measure designed to assess codependent traits. Exploratory factor analysis of the CCS, using data from 301 adults from the general population and 49 attending members of Codependents Anonymous (CoDA), yielded three factors: self-sacrifice, interpersonal control, and emotional suppression. The scale and its subscales exhibited good internal consistency. Consistent with the tenets of the codependency model, higher codependency scores were significantly associated with higher levels of depression, anxiety, stress, and familial dysfunction and lower levels of narcissistic tendencies, self-esteem, and emotional expressivity. Furthermore, the revised measure effectively discriminated members of CoDA from those in the general population.
