Reliability and validity of the Static-2002 among adult sexual offenders with reference to treatment status

Psychometric properties were reported for the Static-2002 using a sample of 464 sexual offenders followed for an average of 5.9 years after release. Correlations between theoretically relevant variables (using indices of lifestyle instability, sexual deviance, psychopathy) and the Static-2002 content area subscales reflected the conceptual emphasis underlying the content areas. An exploratory factor analysis revealed a five-factor solution generally congruent with the conceptual structure of the Static-2002. Survival analyses indicated not all of the content areas had incremental validity in the prediction of either sexual or any violent recidivism. Moderate-to-high levels of predictive accuracy for total score were achieved for treatment completers, dropouts, and refusers across four recidivism outcomes. Three risk categories were identified with significantly different rates of both sexual and any violent recidivism; failure rates and likelihood ratios for these risk categories over 5-, 7-, and 10-year follow-up periods were reported.
