An Updated Sexual Homicide Crime Scene Rating Scale for Sexual Sadism (SADSEX-SH)

The Sexual Homicide Crime Scene Rating Scale for Sexual Sadism (SADSEX-SH) is a rating scale which dimensionally measures the degree of offender sexual sadism in suspected sexual homicide cases. Scoring is accomplished using crime scene and related investigative information. Preliminary norms for the SADSEX-SH prototype indicate that it correctly classified offenders with and without sexual sadism. This study further assessed SADSEX-SH sensitivity, specificity, and inter-rater reliability by comparing a larger sample of male sexual homicide offenders with (n = 20) and without (n = 20) sexual sadism. Two items generally undetectable at crime scenes were removed from the originally proposed 10-item scale, resulting in a final 8-item version. SADSEX-SH total scores for the two groups significantly differed (7.7 ± 3.5, range = 2-14 vs. 2.6 ± 2.0, range = 0-7, t = 5.58, p < .001). Inter-rater reliability was excellent (intraclass correlation coefficients [ICCs] = 0.6-1.0). Using a revised cutoff score of 6, sensitivity was 70.0% and specificity was 90%. This revised scale may prove useful for investigators, clinicians, and institutional professionals in helping to identify and address sexual sadism in sexual homicide offenders.

Predicting internet pornography use and arousal: the role of individual difference variables

This study considers the relation between a number of theoretically relevant individual difference variables and individuals' online pornography use and arousal patterns. In doing so, an attempt is also made to determine whether self-reports of arousal can be collapsed into meaningful empirically derived content groupings. An exploratory factor analysis produces 3 factors for men: standard fare, specialized, and male-focused; and two factors for women: standard fare and specialized. Findings indicate that sexual disposition is a strong predictor of standard fare use and arousal for both genders. Men and women higher in psychopathy were more likely to use all forms of content. For those high in psychopathy, however, men were only slightly, and women not at all, more likely to find standard fare content arousing. Results are discussed in terms of their potential value for understanding an often overlooked first step in the process of pornography consumption.

The "polymorphously perverse" psychopath: understanding a strong empirical relationship

The relationship between psychopathy and sexual offending has been empirically established, but it is little understood. The author proposes nine explanations to provide a conceptual basis for this empirical relationship: (1) search polygyny, (2) callousness and a lack of empathy, (3) a lack of attachment or bonding, (4) sensation seeking as a product of chronic cortical underarousal, (5) grandiosity, (6) entitlement, (7) a predominance of part-object relations, (8) a high frequency of predatory violence, and (9) the leaving by consensual sex partners when the psychopathy is identified. These explanations, constructed from anthropological, psychobiological, attachment, psychoanalytic, and aggression research, find some direct and indirect empirical support in the extant literature. They contribute to understanding the "polymorphously perverse" sexuality of the psychopath.
