Psychopathy as a Predictor Variable of The Disposition to Steal

Abstract

espanol: El proposito del estudio fue comparar la capacidad predictiva de la psicopatia y algunas variables sociodemograficas, sobre la disposicion a robar. La muestra estaba compuesta por 100 prisioneros (86 hombres y 14 mujeres; M = 30.21 anos, DE = 8.42) y 100 participantes de poblacion general (86 hombres y 14 mujeres; M = 26.86 anos, DE = 7.31). La psicopatia y la disposicion a robar se midieron con autoreportes, y se usaron varios analisis de regresion multiple. Los resultados muestran que solo en los presos las variables sociodemograficas tienen valor predictivo (R² = 3.20%, tamano del efecto pequeno). La psicopatia predice significativamente la disposicion a robar, con un tamano del efecto grande, tanto en la comunidad (R² = 67.90%) como en los presos (R² = 72.80%). El componente interpersonal (R² = 75.30%) predice mucho mejor que el afectivo (R² = 23%) en presos, pero el afectivo (R² = 51.20%) predice casi tan bien como el interpersonal (R² = 63.40%) en la poblacion general. Se discuten las implicaciones de los hallazgos para la investigacion, el diagnostico y la intervencion. EnglishThe aim of this study was to compare the capacity of psychopathy and some socio-demographic variables in the prediction of the disposition to steal. The sample was composed of 100 prisoners (86 men and 14 women; M = 30.21 years, SD = 8.42) and 100 participants from general community (86 men and 14 women; M = 26.86 years, SD = 7.31). Psychopathy and disposition to steal were assessed through self-report scales and several multiple-regression techniques were performed. Results show that socio-demographic variables are significant predictors of the disposition to steal only in the group of prison population (effect size was small, R² = 3.20%). The psychopathy is a significant predictor of the disposition to steal among prison population (large effect size: R² = 72.80%) as well as among participants from the general community (large effect size: R² = 67.90%). The interpersonal dimension of psychopathy has a greater predictive value (R² = 75.30%) than the affective dimension (R² = 23%) among prisoners; nevertheless, the predictive values of the affective dimension (R² = 51.20%) and the interpersonal dimension (R² = 63.40%) are similar among participants from the general community. The implications of these findings for diagnosis, intervention and future research are discussed.
