One difficulty in studying the long-term impact of divorce on children has been the lack of a reliable and valid measure of parental conflict for divorced parents. Items for a post-divorce conflict scale were written and tested using 32 male and 63 female college students from divorced families for Study 1 and 60 male and 75 female students from divorced families in Study 2. Using rational, factor analytic, and internal consistency methods, three subscales--Verbal, Physical, and Indirect Hostility--were developed. Alphas for the revised measure were 0.93 for the total Mother- and Father-Conflict scales. Alphas for the subscales ranged from 0.80 to 0.92. The patterns of correlations between each subscale and other measures support the validity of verbal, physical, and indirect hostility as separate constructs. Appendix A contains the scale, and Appendix B contains six tables of study data. (Author/SLD)
