Development and initial reliability and validity of a new measure of distorted maternal representations: The Mother–Infant Relationship Scale

Abstract

Distorted maternal representations (DMRs)—mother's ideas, understanding, and feelings about the infant—shape early interaction and the emerging relationship. Distorted interactions reportedly affect infant attachment and socioemotional development and may be associated with maternal early adversity and trauma. Limited measures are available that could be used as screening tools of DMRs. The aims of this study were to (a) describe the development of the Mother–Infant Relationship Scale (MIRS) and (b) to evaluate its psychometric properties. The development and validation of the MIRS closely followed standard guidelines for the development of psychometric tests. Psychometric properties were ex..
