Background: Attempts to predict prison recidivism based on the personality have not been very successful. This study aims to provide data on recidivism prediction based on the scores on a personality questionnaire. For this purpose, a predictive model combining the actuarial procedure with a posteriori probability was developed, consisting of the probabilistic calculation of the effective verification of the event once it has already occurred. Method: Cuestionario de Personalidad Situacional (CPS; Fernández, Seisdedos, & Mielgo, 1998) was applied to 978 male inmates classified as recidivists or non-recidivists. Results: High predictive power was achieved, with the area under the curve (AUC) of 0.85 (p <.001; Se = 0.012; 95% CI [0.826, 0.873]. The answers to the CPS items made it possible to properly discriminate 77.3% of the participants. Conclusions: These data indicate the important role of the personality as a key factor in understanding delinquency and predicting recidivism.
Predicción psicométrica de la reincidencia penitenciaria. Antecedentes: los intentos para predecir la reincidencia penitenciaria basándose en la personalidad no han tenido mucho éxito. Este trabajo tiene como objetivo ofrecer datos sobre la predicción de la reincidencia a partir de las puntuaciones en un cuestionario de personalidad. Método: se aplicó el Cuestionario de Personalidad Situacional (CPS; Fernández, Seisdedos y Mielgo, 1998) a 978 reclusos varones clasificados como reincidentes o no reincidentes y se elaboró un modelo predictivo combinando el procedimiento actuarial con el concepto de probabilidad a posteriori, consistente en realizar cálculo probabilístico a partir de la constatación efectiva del suceso una vez ya se ha producido. Resultados: se logró un elevado poder predictivo, siendo el área bajo la curva (AUC) de 0.85 (p<0.001; Se = 0.012; 95% IC [0.826, 0.873]. Las respuestas a los ítems del CPS permitieron discriminar adecuadamente al 77,3% de los participantes. Conclusiones: estos datos indican el papel importante de la personalidad como factor clave para entender la delincuencia y predecir la reincidencia.
