Atypical Modulations of N170 Component during Emotional Processing and Their Links to Social Behaviors in Ex-combatants.

ABSTRACT: Emotional processing (EP) is crucial for the elaboration and implementation of adaptive social strategies. EP is also necessary for the expression of social cognition and behavior (SCB) patterns. It is well-known that war contexts induce socio-emotional atypical functioning, in particular for those who participate in combats. Thus, ex-combatants represent an ideal non-clinical population to explore EP modulation and to evaluate its relation with SCB. The aim of this study was to explore EP and its relation with SCB dimensions such as empathy, theory of mind and social skills in a sample of 50 subjects, of which 30 were ex-combatants from illegally armed groups in Colombia, and 20 controls without combat experience. We adapted an Emotional Recognition Task for faces and words and synchronized it with electroencephalographic recording. Ex-combatants presented with higher assertion skills and showed more pronounced brain responses to faces than Controls. They did not show the bias toward anger observed in control participants whereby the latter group was more likely to misclassify neutral faces as angry. However, ex-combatants showed an atypical word valence processing. That is, words with different emotions yielded no differences in N170 modulations. SCB variables were successfully predicted by neurocognitive variables. Our results suggest that in ex-combatants the links between EP and SCB functions are reorganized. This may reflect neurocognitive modulations associated to chronic exposure to war experiences.

Project description:BackgroundFollowing the 2016 Peace Agreement with the Fuerzas Armadas Revolucionarias de Colombia (FARC), Colombia promised to reincorporate more than 13,000 guerrilla fighters into its healthcare system. Despite a subsidized healthcare insurance program and the establishment of 24 Espacios Territoriales de Capacitación y Reincorporación (ETCRs-Territorial Spaces for Training and Reintegration) to facilitate this transition, data has shown that FARC ex-combatants access care at disproportionately lower rates, and face barriers to healthcare services.MethodsSemi-structured interviews were conducted with FARC health promoters and healthcare providers working in ETCRs to determine healthcare access barriers for FARC ex-combatants. Analysis was completed with a qualitative team-based coding method and barriers were categorized according to Julio Frenk's Domains of Healthcare Access framework.ResultsAmong 32 participants, 25 were healthcare providers and 7 self-identified as FARC health promoters. The sample was majority female (71.9%) and worked with the FARC for an average of 12 months in hospital, health center, medical brigade, and ETCR settings. Our sample had experiences with FARC across 16 ETCRs in 13 Departments of Colombia. Participants identified a total of 141 healthcare access barriers affecting FARC ex-combatants, which affected healthcare needs, desires, seeking, initiation and continuation. Significant barriers were related to a lack of resources in rural areas, limited knowledge of the Colombian health system, the health insurance program, perceived stigma, and transition process from the FARC health system.ConclusionsFARC ex-combatants face significant healthcare access barriers, some of which are unique from other low-resource populations in Colombia. Potential solutions to these barriers included health insurance provider partnerships with health centers close to ETCRs, and training and contracting FARC health promoters to be primary healthcare providers in ETCRs. Future studies are needed to quantify the healthcare barriers affecting FARC ex-combatants, in order to implement targeted interventions to improve healthcare access.
