Measurement and Correlates of Zoophilic Interest in an Online Community Sample

Sexual interest in animals (zoophilia) is a scant investigated topic owing partially to difficulties in assessing the behavior outside of a clinical setting. While there have been previous attempts to categorize individuals with a sexual interest in animals into classification systems, this requires extensive clinical interviews and psychometric testing. Previous classifications also lack clarity on the adjacent concept of furryism (i.e., interest in anthropomorphized animals) and how it may be related to zoophilia. As there are currently no validated psychometric measures of zoophilia, individuals with a sexual interest in animals are a challenging population to research and may be underdetected in clinical settings. The central aim of the present study was to examine the measurement and correlates of sexual attraction to nonhuman animals through the development and refinement of psychometric and visual stimulus measures of animal sexual interest. Participants included 1,228 respondents (72% zoophilic and 35% furries; 67% men and 22.9% women) recruited from the online community. The results indicated that a Sexual Interest in Animals-Self-Report (SIA-SR) scale had four distinct subscales with excellent discrimination for self-reported zoophilia. Moreover, endorsement of sexual interest in horses and dogs from visual stimuli was most common among the individuals in the sample, while dog and horse sexual and romantic attractiveness ratings also had the largest and most consistent associations with SIA-SR scores and self-reported zoophilia. The results contribute to a greater understanding of the sexual interest patterns for persons with zoophilia and have implications for theory, future research, and clinical practice.
