Objective: Sexual arousability is defined as an ability to react with sexual arousal in response to external and internal stimuli. Sexual arousability measures are important for research purposes and for diagnostics of sexual dysfunctions. Self-assessment techniques can be used for such measurement. Due to absence of Polish-language psychometric tools dedicated to sexual arousability measures we adapted Sexual Arousability Inventory; (SAI; Hoon et al., 1976). Design and Method: Psychometrical characteristic of Polish version of SAI (SAI-PL) was examined in the study with 132 participants (42 females, 90 males) aged 18 – 45. Participants were recruited through the student groups, support groups, non-profit organization, Internet, and personal contact. Validation with behavioral factors was performed on the group of 39 heterosexual males consuming pornography on the weekly basis. Results: SAI-PL has a very high internal consistency (Cronbach’s alpha = .912), and the same structural factor as original SAI. In addition, the results indicate the high accuracy of the tool relative to the group of men that has not been verified in previous studies devoted to the English version, validated only on a group of women. Conclusions: Due to the simple construction and good psychometric properties SAI-PL can be successfully used to diagnose sexual arousability disorders, in the assessment of the therapy, as well as for research purposes.
