Accuracy of the static-99 in predicting recidivism in Switzerland.
The Static-99 is a widely used actuarial risk assessment instrument. Various international validation studies have found satisfactory to good predictive validity for the Static-99, with the area under the curve (AUC) between 59% and 95%. This study is the first evaluation of the predictive accuracy of the Static-99 among sex offenders in Switzerland. The Static-99 scores of 69 violent/sex offenders in Switzerland were assessed using data from their psychiatric assessments. Recidivism was operationalized as reconviction assessed from penal records. The Static-99 risk levels were predictive for recidivism (AUC = .758) among our population. The results are discussed on the basis of the literature.
