In 2007, New York enacted the Sex Offender Management and Treatment Act, empowering the state to civilly manage individuals who have committed sexual offenses (respondents) and are deemed to have a mental abnormality (MA) that predisposes them to sexually recidivate after serving their criminal sentences. We sought to replicate and extend a previous study (Lu et al., 2015) to identify factors predicting legal decisions. We predicted, on the basis of previous research, that clinical information (e.g., diagnosis) as well as empirically supported risk factors (e.g., sexual deviance) would predict trial outcomes. We analyzed multiple pieces of demographic, criminogenic, and clinical data on three nested subsamples of respondents on the basis of the legal process: MA consent (n = 713), MA trial (n = 316), and disposition hearing (n = 643). The binary outcomes of interest were as follows: For the MA consent subsample, it was whether the respondent waived their MA trial; for the MA trial subsample, it was whether the respondent was found at trial to have an MA; and for the disposition hearing, it was whether the respondent was ordered to inpatient or outpatient civil management. The strongest predictor of waiving the trial was geographic location; respondents outside New York City and Long Island were more likely to waive their trials (ORs = 2.38-3.37). The strongest predictors of MA trial and disposition hearing outcomes were Diagnostic and Statistical Manual of Mental Disorders diagnoses; pedophilia (ORs = 4.05-7.22) and sexual sadism (ORs = 2.68-7.03) diagnoses increased the likelihood of an MA finding and confinement order. Judges and juries give significant weight to clinical information, particularly pedophilia diagnoses, when making civil management legal decisions.
