Development, acceptability and construct validity of the Aboriginal Women’s Experiences of Partner Violence Scale (AEPVS): a co-designed, multiphase study nested within an Australian Aboriginal and Torres Strait Islander birth cohort

Abstract

ObjectiveFew studies employ culturally safe approaches to understanding Indigenous women’s experiences of intimate partner violence (IPV). The aim of this study was to develop a brief, culturally safe, self-report measure of Aboriginal and Torres Strait Islander women’s experiences of different types of IPV.DesignMultistage process to select, adapt and test a modified version of the Australian Composite Abuse Scale using community discussion groups and pretesting. Revised draft measure tested in Wave 2 follow-up of an existing cohort of Aboriginal families. Psychometric testing and revision included assessment of the factor structure, construct validity, scale reliability and acceptability to create the Aboriginal Women’s Experiences of Partner Violence Scale (AEPVS).SettingSouth Australia, Australia.Participants14 Aboriginal women participated in discussion groups, 58 women participated in pretesting of the draft version of the AEPVS and 216 women participating in the Aboriginal Families Study completed the revised draft version of the adapted measure.ResultsThe initial version of the AEPVS based on item review and adaptation by the study’s Aboriginal Advisory Group comprised 31 items measuring physical, emotional and financial IPV. After feedback from community discussion groups and two rounds of testing, the 18-item AEPVS consists of three subscales representing physical, emotional and financial IPV. All subscales had excellent construct validity and internal consistency. The AEPVS had high acceptability among Aboriginal women participating in the Aboriginal Families Study.ConclusionsThe AEPVS is the first co-designed, multidimensional measure of Aboriginal women’s experience of physical, emotional and financial IPV. The measure demonstrated cultural acceptability and construct validity within the setting of an Aboriginal-led, community-based research project. Validation in other settings (eg, primary care) and populations (eg, other Indigenous populations) will need to incorporate processes for community governance and tailoring of research processes to local community contexts.
