Development and Validation of the Interpersonal Hate Questionnaire (IHQ)

This series of studies developed and validated a multidimensional measure of interpersonal hate, the Interpersonal Hate Questionnaire (IHQ). Using three independent samples (N₁ = 221, N₂ = 183, N₃ = 360), we conducted exploratory and confirmatory factor analyses that revealed three robust dimensions of interpersonal hate: Fear of Social Consequences, Dehumanization, and Aggressive Urges. The IHQ demonstrated excellent internal consistency (α = .93) and construct validity through significant correlations with related psychological constructs. Fear of Social Consequences showed the strongest relationship with anxiety (r = .49, p less than .001), while Aggressive Urges correlated most strongly with anger rumination (r = .50, p less than .001). The IHQ showed good model fit (TLI = 0.946, RMSEA = .059) and factorial consistency across diverse samples. These findings advance our understanding of hate as a distinct emotional construct and provide a reliable tool for assessing its key dimensions. The scale's strong psychometric properties and clear factor structure make it valuable for applications in understanding and addressing interpersonal hate.
