Abstract

Twenty-seven erotic and sexually neutral movie clips were shown to 191 men, consisting of 62 heterosexual intrafamilial child sexual abusers, 57 heterosexual and 25 homosexual extrafamilial child sexual abusers and 47 community controls. The stimuli depicted males and females from ages 6 to 25 years. Maximum penile volume changes were recorded during the 30 second stimulus presentations. Analyses showed that the phallometric test had high internal consistency (alpha=0.93) and revealed the expected erotic preference profiles for controls and extrafamilial offender groups. The homosexual group reacted most to 13–15 year old boys which made them more easily discriminated from the other groups. The intrafamilial offenders, however, overlapped considerably with controls and only 10% showed a pattern of penile responses expected for the ‘classical pedophile’, i.e., largest responses to female children. The pattern of results supported the accumulating evidence that child sexual abusers are heterogeneous in terms of their sexual preference profiles.
