The study described in this article tested the psychometric properties of the Intergenerational Congruence in Immigrant Families--Parent Scale (ICIF-PS), an instrument developed to assess intergenerational conflict in immigrant families and evaluate interventions to ameliorate the conflict. ICIF-PS's psychometric properties were tested in a sample of 787 Chinese American immigrant parents selected from a subset of participants in the Chinese American Psychiatric Epidemiologic Study, a strata cluster survey using a probability design. The ICIF-PS was shown to be a unidimensional measure of intergenerational-intercultural congruence with good psychometric properties.
