Abstract
The present study examined the construct validity of the Violence Risk Scale-Sexual Offender version (VRS-SO) through an examination of its factor structure and convergence with psychological measures assessing conceptually relevant constructs in a sample of 732 treated incarcerated adult male sex offenders. The VRS-SO was rated prospectively pre- and posttreatment by service providers, and several of the men had completed a psychometric battery at each time point. Prospective Stable 2000 ratings were examined for comparison purposes. Results of exploratory longitudinal factor analysis, performed on VRS-SO pre- and posttreatment dynamic item scores, supported a three-factor model (comparative fit index = .990) and the measurement invariance of the loadings over time. A stringent longitudinal confirmatory factor analysis of the VRS-SO items also supported the three-factor structure. Scores from the three factors (Sexual Deviance, Criminality, and Treatment Responsivity) were correlated in conceptually meaningful ways with scores from the Stable 2000 and selected psychometric measures. The results provide evidence for the construct validity of VRS-SO test scores as providing an index of sex offender risk and, more specifically, that its item content and factor domains measure psychological constructs pertinent to sex offender risk and need.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
