Objective Based on hypotheses generated during clinical interviews with 80 women with a lifetime history of bulimia nervosa (BN), we designed an instrument for assessing the extent to which women with BN report parental intrusiveness and breakdown of appropriate role boundaries during their adolescent development. Method Through an iterative process of item generation and scale administration, the Parental Intrusiveness Rating Scale (PIRS), consisting of 20 maternal items and 20 paternal items, was developed. Maternal subscales include Invasion of Privacy, Jealousy and Competition, and Overconcern with the Daughter's Eating, Weight, and Shape. Paternal subscales include Invasion of Privacy, Seductiveness, and Overconcern with the Daughter's Eating, Weight, and Shape. We validated the instrument using a subset of the above BN and comparison women ( n s = 55 and 33, respectively), as well as an independent sample of women with BN and college comparison subjects ( n s = 31 and 540, respectively). Results Parental intrusiveness scores were significantly positively correlated with disturbed relationships in the family of origin of our initial cohort. Reliability analyses, both test‐retest and item‐scale correlations, revealed adequate to strong statistical associations in the combined sample. Conclusion The PIRS promises to enrich our understanding of problematic parental behaviors among women who develop BN and allows us to broaden the conceptualization of familial risk factors for this disorder. © 2000 by John Wiley & Sons, Inc.
