Development and Psychometric Assessment of a Questionnaire for the Detection of Invisible Violence against Women

Background. Invisible violence against women (IVAW) can be understood as the set of attitudes, behaviors, and subtle beliefs that men use to subordinate women and that are culturally accepted. These behaviors can be a risk factor for intimate partner violence (IPV), so it is important to design tools that allow us to detect it early. The aim of this study was to design and psychometrically assess a questionnaire for the detection of invisible violence against women (Q-IVAW). Methodology. A descriptive cross-sectional methodological study carried out in three phases: (1) development of the initial version; (2) pilot study (N = 51); and (3) final validation study (N = 990). The tool's reliability, validity, and legibility were assessed. To assess reliability, the internal consistency (Cronbach's alpha) was analyzed. The validity assessment included an analysis of content, criterion, and construct validity. Results. The EFA revealed that the Q-IVAW was comprised of five factors that explained 55.85% of the total variance found. The Q-IVAW showed very high reliability (alpha = 0.937), excellent content validity, and good construct validity. The criterion validity analysis showed a moderate correlation between A-IPVAW and Q-IVAW (r = 0.30; p < 0.001). Conclusion. The psychometric assessment of the Q-IVAW yielded good results, which could support the tool's ability to assess how often women are subjected to inviable violent behaviors by their partners.
