Scale of negative family interactions: a measure of parental and sibling aggression.

This article examines a measure of received emotional, physical, and sexual aggression within the family: the Scale of Negative Family Interactions (SNFI). Unlike traditional familial violence scales that measure parental aggression alone, the SNFI simultaneously measures sibling violence for a more comprehensive examination of familial aggression. Although a variety of scales may be used in researching parental abuse, the SNFI is uniquely intended for (a) examining sibling violence while controlling for parental aggression, (b) examining parental abuse while controlling for sibling violence, and (c) comprehensively examining family violence to include aggression from both parents and siblings. Test-retest and internal consistency reliability were demonstrated, and evidence for validity is presented. In addition to offering a measure of sibling and parental aggression, the SNFI has the advantages of including everyone in the role of parent or sibling and of measuring a wide variety of emotional, physical, and sexual aggression within the family.
