For security and justice professionals (e.g., police officers, lawyers, judges), the thousands of peer-reviewed articles on nonverbal communication represent important sources of knowledge. However, despite the scope of the scientific work carried out on this subject, professionals can turn to programs, methods, and approaches that fail to reflect the state of science. The objective of this article is to examine (i) concepts of nonverbal communication conveyed by these programs, methods, and approaches, but also (ii) the consequences of their use (e.g., on the life or liberty of individuals). To achieve this objective, we describe the scope of scientific research on nonverbal communication. A program (SPOT; Screening of Passengers by Observation Techniques), a method (the BAI; Behavior Analysis Interview) and an approach (synergology) that each run counter to the state of science are examined. Finally, we outline five hypotheses to explain why some organizations in the fields of security and justice are turning to pseudoscience and pseudoscientific techniques. We conclude the article by inviting these organizations to work with the international community of scholars who have scientific expertise in nonverbal communication and lie (and truth) detection to implement evidence-based practices. Análisis de la comunicación no verbal: los peligros de la pseudociencia en entornos de seguridad y justicia R E S U M E N Para los profesionales de la seguridad y la justicia (policías, abogados, jueces), los miles de artículos revisados por pares sobre comunicación no verbal representan fuentes importantes de conocimiento. Sin embargo, a pesar del alcance del trabajo científico realizado sobre este tema, los profesionales pueden recurrir a programas, métodos y enfoques que no reflejan el estado real de la ciencia. El objetivo de este artículo es examinar (i) los conceptos de comunicación no verbal transmitidos por estos programas, métodos y enfoques, pero también (ii) las consecuencias de su uso (por ejemplo, sobre la vida o la libertad de las personas). Para lograr estos objetivos, describimos el alcance de la investigación científica sobre la comunicación no verbal. Se examina un programa (SPOT: Evaluación de pasajeros mediante técnicas de observación), un método (BAI: Entrevista de análisis de conducta) y un enfoque (sinergología) que contradicen el estado de la ciencia. Finalmente, presentamos cinco hipótesis para explicar por qué algunas organizaciones en los campos de la seguridad y la justicia están recurriendo a la pseudociencia y a las técnicas pseudocientíficas. Concluimos el artículo invitando a estas organizaciones a trabajar con la comunidad académica internacional especializada en la investigación sobre comunicación no verbal y detección de mentiras (y verdad) para implementar prácticas basadas en la evidencia.

El presente trabajo analiza la aplicabilidad y limitaciones de uno de los procedimientos más empleado para analizar la credibilidad de un testimonio, el SVA. El punto de partida para su correcta aplicación es una consideración exhaustiva de las posibles fuentes que pudieran dar origen a una declaración siguiendo el método de falsación de hipótesis. Se describen los principales errores en su utilización y se clarifican los métodos indicados para las diferentes hipótesis a ser analizadas, contemplando tanto la pertinencia de cada procedimiento como sus limitaciones. Se concluye acerca de los peligros de una incorrecta o incompleta aplicación del SVA al margen del planteamiento de hipótesis y la técnica recomendada para su valoración, como a su vez el riesgo de sobregeneralizar el uso de los análisis de contenido (CBCA).

The present article studies war-related trauma and its effects on children living in the Gaza Strip, 6 months after the attack launched by the Israeli army on July 8, 2014, which lasted for 51 days. The objective was twofold: (a) to identify the prevalence of exposure to traumatic events and (b) to examine the symptoms of traumatic stress in children as described by their parents or tutors using the Harvard Trauma Questionnaire (HTQ). Data from 1,850 male and female children aged between 6 and 15 years living in the Gaza Strip were collected throughout the months of February and April 2015, that is 6 months after the attack. Results showed that the majority of the children were exposed to bombardments and residential area destruction (83.51%), were confined at home unable to go outside (72.92%), were witness to the profanation of mosques (70.38%), were exposed to combat situations (66.65%), and saw corpses (59.95%). A sample of 275 males (28.3%) and 232 females (26.5%) showed diagnoses of posttraumatic stress disorder (PTSD). Gender and age were independent of PTSD. The presence of this pathology was positively related to the number of trauma events experienced. The type of traumatic experience was hardly related to age and gender. A greater protection on behalf of the families against exposure to traumatic events could explain these differences.

The aim of this study consisted in analysing the cases of drug-facilitated sexual assault-chemical submission-from 2008 to 2017. A total of 240 cases registered during this period within the territorial area of the Spanish Civil Guard were analysed. Results show an increasing incidence of sexual assault cases that are drug-facilitated in order to annul the will of the victim, or at least that there is a greater awareness to report these cases. From the analyses carried
