EducationPh.D., Universiteit van Amsterdam (The Netherlands), 1995M.A., Universiteit van Amsterdam, 1988 Research StatementProf. Dr. Janssen's research interests include the psychophysiology of sexual desire and arousal, the effects of emotions on sexual response and behavior, and relationships, sexuality, and health. With his research he aims to improve our understanding of the factors and processes that influence sexual and relationship satisfaction and of the determinants of risky sexual decision making, sexual dysfunction, sexual compulsivity, and sexual aggression.A large part of Prof. Dr. Janssen's work focuses on the award-winning Dual Control Model of Sexual Response, which he introduced with John Bancroft, M.D. and which, with its focus on individual differences in the propensity for sexual excitation and inhibition, opened up a new research agenda with wide relevance. The model is being used and tested by researchers around the world in studies on sexual health topics as varied as sexual risk taking, sexual dysfunction, sexual compulsivity, and sexual aggression. Studies in over 45,000 men and women have consistently shown that large individual differences exist in sexual excitation and inhibition proneness, and suggest that this variability is associated with, on the one end, a vulnerability to sexual dysfunction and, on the other end, an increased likelihood of engaging in risky sexual risk behaviors (including sexual infidelity) and sexual aggression.Prof. Dr. Janssen also studies the relationship between sexual and nonsexual emotions (e.g., happiness, sadness, anger) and how these, separately and in interaction, influence sexual functioning, behavior, and satisfaction, in individuals as well as in couples. In approaching this work, Dr Janssen applies questionnaire, experimental, observational, psychophysiological (including fMRI), daily diary, as well as interview and focus group methods.
