Development and validation of the Informal Supporter Readiness Inventory (ISRI).

OBJECTIVE: This article outlines the development and validation of the Informal Supporter Readiness Inventory (ISRI), based on the model developed by the present authors in (Davies, 2023). This scale assesses the readiness of informal supporters to intervene or provide support in situations of intimate partner violence (IPV). METHODS: The research followed a three-phased procedure of item development, scale development, and scale evaluation; adhering to best practice guidelines for psychometric development and validation. This process provided empirical substantiation for the domains of the Model of Informal Supporter Readiness (Davies, 2023). RESULTS: The 57-item ISRI incorporates four primary factors: normative, individual, goodman-emotional, and situational-assessment. These factors demonstrated robust internal consistency and factor structures. Additionally, the ISRI evidenced strong test-retest reliability, and both convergent and divergent validity. Although aligning closely with the Model of Informal Supporter Readiness, the scale revealed a nuanced bifurcation of situational factors into situational-emotional and situational-assessment. DISCUSSION: The ISRI offers an important advancement in IPV research by highlighting the multifaceted nature of informal supporter intervention. The findings have several implications, from tailoring individualised supportive interventions to strengthening support networks and empowering survivors. The present study's findings underscore the potential of adopting a social network-oriented approach to interventions in IPV scenarios. Applications for research and practice are discussed.

A systematic review of informal supporters of intimate partner violence survivors: the intimate partner violence model of informal supporter readiness.

Background: Intimate partner violence (IPV) is a serious public health issue that consists of physical, sexual, and psychological violence perpetrated by a current or former partner. Informal supporters (e.g., family and friends) of survivors are more often witness to IPV or are the first people a survivor will disclose abuse to and are more able to provide consistent ongoing support than professional services. Therefore, greater understanding of informal supporters is warranted to aid in reducing the risks experienced by survivors. This systematic review aimed to: (1) identify factors associated with either an increase or decrease in helping behaviour toward a survivor, (2), identify the most effective self-care strategies employed by informal supporters, and (3) consider the current theoretical approaches used to understand informal supporters help-giving behavioural intention. Methods: A systematic literature search was conducted following the PRISMA guidelines. The search included English language articles published between 2005 and 2021 in the databases Psych Articles, Scopus, Proquest Social Services Abstracts, and Ebscohost. Studies were included if the primary research aims explored the motivators and inhibitors of helping intention or self-care strategies of adult social network members of adult IPV survivors. Two reviewers independently screened all identified articles for inclusion suitability. Results: One hundred and twenty articles were subjected to full text screening resulting in 31 articles being identified as meeting inclusion criteria. Synthesis of the findings identified the following three key areas associated with help-giving behavioural intentions: normative factors, individual factors, and situational factors. There were no articles identified that considered self-care of informal supporters. Of the 31 articles, 22 had a theoretical underpinning. None of the utilised theories explained all three of the identified factors of help-giving behavioural intention. Conclusion: These results are integrated into a proposed Intimate Partner Violence Model of Informal Supporter Readiness (IPV-MISR), incorporating the identified factors associated with help-giving behavioural intention. This model provides a framework for conceptualising the readiness of an informal supporter to provide adequate support to IPV survivors. The model extends existing theoretical standpoints and has utility in both practice and research.
