La evidencia meta-analítica indica que las tasas de reincidencia sexual oscilan entre el 15 y el 20% tras periodos de seguimiento que llegan hasta los veinte años. Se pueden establecer distintos perfiles de agresores sexuales en base a su reincidencia: los agresores especializados no reincidentes, los agresores reincidentes no especializados y los agresores sexuales especializados reincidentes. El grupo de los agresores especializados no reincidentes es el que suscita más preguntas. Este trabajo aborda qué factores psicológicos caracterizan a cada uno de estos perfiles y una posible explicación para las bajas tasas de reincidencia. Se discuten algunas implicaciones prácticas relevantes.

Empirical literature has yielded a positive association between psychopathy levels and suicide attempts. This association is centred around impulsivity and disinhibitory facets of psychopathy, whereas suicide and emotional poverty remain independent. Evidence about the relation between suicide and psychopathy in mentally disordered offenders is not conclusive. The present work explores the relation between several measures of antisocial personality, suicide attempt and deliberate self mutilation in a sample of inmates from a forensic psychiatric hospital. Results support the association between disinhibitory aspects of personality and suicide in this population.

El interés sexual hacia menores ofrece numerosas dificultades para su evaluación, principalmente, la motivación para ocultarlo en contextos forenses. Su asociación con la reincidencia en delitos sexuales y su utilidad como medida del éxito terapéutico han impulsado el desarrollo de distintas técnicas de evaluación. En este artículo se revisan los autoinformes, la pletismografía peneana y varias medidas cognitivas basadas en la latencia de respuesta. Aunque todas las técnicas presentan limitaciones en cuanto a su manipulación y a su capacidad discriminativa, las baterías multimétodo parecen ofrecer la mejor alternativa y son una vía de investigación futura.

Abstract:Here we analyze the simultaneous relationships among five variables. Two refer to childhood (episodes of various forms of maltreatment and externalizing behaviors), whereas three refer to early adulthood (intelligence, personality, and socialization difficulties). The 120 individuals considered for the present report were invited from the 650 schoolchildren participating in the Longitudinal Study of Intelligence and Personality (Minas Gerais, Brazil). The complete sample was recruited in 2002 (T1; mean age = 10.0; standard deviation (SD) = 2.2) and 120 were tested again in 2014-17 (T2; mean age = 23.5; SD = 2.2). Externalizing behaviors were registered at T1, whereas the remaining variables were obtained at T2. These were the main results: (1) externalizing behaviors predict future social effectiveness (as estimated by the general factor of personality derived from the NEO Personality Inventory-Revised (NEO-PI-R) and socialization difficulties computed from the socialization scale (SOC)) and future intelligence performance (as assessed by a set of fluid and crystallized tests); (2) episodes of self-reported childhood maltreatment predict social effectiveness, but not intelligence; (3) maltreatment and externalizing behaviors are unrelated; and (4) social effectiveness (personality) and intelligence are unrelated. Therefore, the findings support the dissociation between adult intelligence and personality with respect to maltreatment episodes and externalizing behaviors occurring in childhood. Implications of these findings for social policies aimed at preventing adult socially ineffective personalities are underscored.

In this paper, the basic properties of the convex functions are discussed, such as continuity, directional differentiability, and supportability properties.
