Assessing Social Networks: Validation of the Informal Supporter Readiness Inventory (ISRI) for Use in an Australian Context

Objective. This research aimed to validate the Informal Supporter Readiness Inventory (ISRI) for evaluating the preparedness of informal supporters, in an Australian sample, to provide assistance in the context of intimate partner violence (IPV). Method. The ISRI’s four distinct factors were each assessed with separate confirmatory factor analyses (CFA). Reliability was calculated using Cronbach’s alpha values, and test-retest reliability was evaluated using intraclass correlation coefficients. Additionally, the ISRI’s validity was assessed through Pearson’s correlations with both convergent and divergent measures. Results. The CFAs supported the four distinct factors of the ISRI: normative, individual, situational-emotion, and situational-assessment. The measure exhibited good-to-excellent internal consistency across these factors and good test-retest reliability at four weeks. Convergent validity was supported by a strong positive correlation with the Intent to Help Friends Scale, while its weak association with the Generic Job Satisfaction Scale supported divergent validity. Discussion. The ISRI has emerged as a practical instrument with relevance to certain Australian sociocultural dynamics, offering utility in both research and clinical settings. The ISRI supports a network-oriented approach to IPV survivor support, assisting the alliance between formal and informal support mechanisms. Future research should focus on broadening the ISRI’s applicability by assessing its effectiveness across diverse Australian populations.
