Project
Evaluation of traumatic memories and psychological disorders associated to trauma in refugees. This research aims to evaluate psychological disorders associated with traumatic experiences in victims of war, refugees and asylum seekers, delving into one of its main symptoms (intrusive and recurrent memories of the vivid facts), and resilience factors that could allow develop effective coping strategies. Under the aegis of the United Nations High Commissioner for Refugees (UNHCR), researchers from Spain, Chile, Cuba and Palestine, countries where minors (6-12 years) and adults (18-50 years) will be assessed, will participate in the study. The results obtained allow to establish guidelines for intervention with particularly vulnerable victims of countries that are in conflict, and are welcomed in countries of asylum.

La memoria no graba la realidad tal cual es, sino que la interpreta y reconstruye. En general, podemos considerar tres fuentes básicas de error en la memoria de los testigos: las condiciones de codificación —mientras ocurre el suceso—, las de retención —entre el suceso y la toma de declaración— y las de recuperación —la toma de las manifestaciones de los testigos—. Por efecto de estos factores, la reconstrucción de los recuerdos sobre un lugar, una acción, una cara o, en general, sobre cualquier suceso complejo, puede provocar diferentes errores de memoria. Una adecuada obtención de los testimonios minimizaría estos errores. La evaluación de los factores que pueden afectar a su exactitud facilitaría las decisiones judiciales y policiales.
Objective. To study the relationship between sleep quality and memory in healthy ageing. Methods. The study included 99 people older than 50 years (69 women and 30 men; mean age, 68.74 ± 7.18 years) with no associated diseases. Patients completed digital versions of the Word Learning (WL) and Visual Paired Associates (VPA) tests and the Pittsburgh Sleep Quality Index (PSQI) questionnaire to assess the quality of sleep. Results. PSQI score was negatively correlated with VPA and WL test performance. Performance in these 2 memory tests decreased in line with sleep quality. In addition, performance in VPA test was negatively correlated with subjective sleep quality, duration, and sleep disturbances. Performance on the WL test was negatively correlated with subjective sleep quality and efficiency. Participants’ sex showed a weak effect on VPA performance and sleep latency. Conclusions. Medical professionals working with elderly patients should take into consideration the effect of poor sleep quality on memory. Cognitive impairment in these patients may be a manifestation of a neuroendocrine imbalance due to a disrupted circadian rhythm. More research is needed to prove this hypothesis.
En los delitos sexuales, las características especiales de algunas personas las convierten en víctimas potencialmente vulnerables. Ante la responsabilidad y obligatoriedad legislativa de actuar de manera inmediata en defensa de sus derechos y garantizar su protección, los profesionales del contexto policial y judicial que intervienen en la obtención del testimonio tienen el reto de adaptar los procedimientos para la obtención y evaluación de sus testimonios. Las investigaciones previas confirman desinformación y consiguiente mala praxis policial y judicial en los casos de abuso sexual a víctimas especialmente vulnerables: alta demora en las denuncias, repetición de interrogatorios y uso de preguntas inadecuadas. En el presente artículo se analizan todos estos factores de influencia y se dan algunas recomendaciones para mejorar los procedimientos de obtención de sus testimonios. Finalmente, se alerta sobre la posible sugestión que podría derivarse del mal uso de procedimientos que pretenden mejorarla cantidad de información recuperada, pero que pueden contribuir a generar falsas memorias.
The present study evaluated the quality of life of 1139 surviving victims of the Colombian armed conflict benefited from some actions of reparation, through a brief sociodemographic and victimological survey and the WHO quality of life (WHOQOL-BREF) questionnaire, which takes into account perceived physical and mental health, social relations and environmental factors. The results show that the quality of life of the victims of the armed conflict, once peace agreements had been reached, remained low or medium-low. The number of victimizing events suffered and the time elapsed have little effect on the quality of life, with type of trauma being more relevant. Land-related events fundamentally influenced environmental factors. Kidnappings, sexual assaults and events where minors were involved affected mental health. Victims of sexual assault were those whose quality of life was most affected and torture victims were those with a lower index of global quality of life. To repair the damage caused, special attention should be drawn to the sociodemographic characteristics of each victim, the type of aggression suffered and their needs in the areas of physical and mental health, and economic resources.
