Public perceptions of the severity of intimate partner violence against women (IPVAW) incidents are an important factor that has been linked to key issues regarding this type of violence, such as acceptability or tolerance, personal sense of responsibility, attitudes toward intervention, and the public's, professionals', and victims' responses to IPVAW. The aim of the present study was to provide further validity evidence for the perceived severity of IPVAW scale (PS-IPVAW), by assessing its measurement invariance between gender and age groups, and between men from the general population and male IPVAW offenders. Item response theory was also used to assess the discrimination of the items and their position on the measured latent trait continuum (i.e., perceived severity of IPVAW). To this end, the psychometric properties of the scale were examined in four different samples from the general population (N = 2,627) and in one clinical sample of male IPVAW offenders (N = 200). Our findings showed that the PS-IPVAW scale has excellent internal consistency (α = .89-.90) and a clear one-factor latent structure (CFI = .91-.96, RMSEA = .055-.086), and that partial strict invariance holds across different gender and age groups. We also found that IPVAW offenders' perceptions of the severity of IPVAW may follow a different pattern to that of men from the general population. The PS-IPVAW scale is able to yield accurate assessments of the perceived severity of this type of violence among the general population and IPVAW offenders.
