The development of a four-item scale for the prediction of sexual offending against multiple victims is described. The scale is scored from offender age and details of the victim's age, gender, and relationship to victim. The scale showed high inter-rater reliability for the individual items and the scale as a whole. Validity in predicting multiple offending in a community sample of sexual offenders against children and in a sub-sample of voluntarily-referred offenders was moderate. The scale had a positive and moderately large correlation with the RRASOR. The scale may be useful for risk assessment of child molesters in circumstances where minimal collaborative information about sexual offending is available.Michael Proev
