Document Summary
Harris, g. t. , rice, m. e. , & quinsey, v. l. (1993). Purpose: develop an actuarial risk assessment instrument for the prediction of violent recidivism. 332 admitted for treatment to maximum security psychiatric institution. 286 admitted only for brief pretrial psychiatric assessment. Procedure: all predictor variables were coded retrospectively from institutional files. 20 randomly chosen participants: reliability criterion was set at . 70. For the variables that met this criterion, mean correlation was . 90 and mean kappa was . 83. Separate stepwise discriminant analysis for each set of variables. Entire entire sample (n = 618) sample (n = 618) Randomly selected half of the entire sample. So, married gets a score of -2 and never married gets a score of +1. Scores can range from -27 to +35, with higher scores indicating higher risk higher scores indicating higher risk. The self-appraisal questionnaire: a self-report measure for predicting recidivism versus clinicianadministered measures: a 5-year follow-up study.
