By actuarial, here I mean not only that the items, or criteria, were selected based on their empirical support in the literature, but also that the scale itself has predictive validity studies, having been empirically linked to recidivism. Finally, the scale can be deconstructed into its component items and factors, and each component examined for its ability to predict recidivism. Unfortunately, no reliability indexes are available yet for the SVR Multiple sex offense types Supply and Services Canada: Implications for practice and the education of psychologists and other mental health professionals.

Reviewing their manuals alone will help one prepare for cross-examination on risk assessment, and the items selected have a basis in the empirical literature, although a few such as major mental illness are controversial.
DolanAfshan Khawaja Factors predicting acquittal and lengths of confinement in British Columbia. Of course, if a plethysmograph were essential to assessing sex offender risk, if its elimination from an assessment battery led to poor predictions, and if there were no alternative methods of obtaining information about deviant sexual interest, then the time and money to include it in a standard battery might be defensible.

The HCR has a base of predictive validity studies, with a link to recidivism and good interrater reliability indexes; the SVR, given its newness, does not yet have such studies. Such studies would be helpful in understanding the properties of the items.
The HCR’s total score is used for the above research, although this is not how the authors recommend using the scale in practice. It is not immediately apparent why sexual deviation is placed in psychosocial adjustment, while one of sexual deviation’s best indicators, high density sex offenses, is placed in sexual offenses.
Authorities still write articles urging the seemingly impossible: An introduction with emphasis on findings from a naturalistic test of interrater reliability. Even today, only a few risk assessment instruments are truly actuarial.

Until recently, these clinical risk assessment reports have been divorced from the statistical, actuarial literature on risk assessment. Sex offender risk assessment and the law. Some of the items used are far from agreed upon in the literature.
A meta-analysis of sexual offender recidivism studies. Both instruments will allow the practitioner ajnotated organize and communicate his or her thoughts clearly, perhaps the HCR given its conceptually clearer divisions more so than the SVR Mental disorder and violent behavior. The authors reviewed the literature and selected 20 items for which they found consistent empirical support.
Each instrument is an admirable integration of research and clinical practice.
