Estudios actuales analizan el perfil psicológico y el tipo de decisiones (Betsch & Glöckner, 2010; Evans, & Stanovich, 2013) asociados a la efectividad de rescatistas que asisten psicológicamente a personas afectadas por un desastre (e.g., Azzollini, Depaula, Cosentino, & Bail Pupko, 2018). Se seleccionó una muestra no probabilística intencional de 165 rescatistas del Área Metropolitana y el Gran Buenos Aires, 84 recibieron capacitación en Primera Ayuda Psicológica (PAP) y 81 no. Posteriormente fueron evaluados mediante el Software Interactivo de Primera Ayuda Psicológica (SIPAPSI; Azzollini, Depaula, Bail Pupko, Becerra, & Vidal, 2016), que simula un contexto de emergencia, en el que debe aplicar PAP (Azzollini, Azzara, Depaula, Cosentino, & Grinhauz, 2017; Farchi et al., 2018). Se aplicó Bases for Urgent Decisions under Extreme Circumstances Inventory (BUDECI; Cosentino, Azzollini, Depaula, & Castillo, 2017), para evaluar sus estilos decisorios. Se observó una correlación inversa y estadísticamente significativa entre la efectividad en la aplicación de la PAP (i.e., performance SIPAPSI) y el estilo decisorio urgente afectivo (r = -.27; p = .04) en el grupo de capacitados en PAP. Se concluye que decisiones emocionales de sujetos entrenados operan en detrimento de una óptima aplicación de PAP.

It was selected a nonprobabilistic intentional sample of 165 rescue workers of the Metropolitan Area and Gran Buenos Aires, 84 received training in First Psychological Aid (FPA) and 81 not. Later, they were evaluated by the Interactive Software in First Psychological Aid (ISFPA, Azzollini, Depaula, Bail Pupko, Becerra, & Vidal, 2016), that simulated an emergency context in which they have to give FPA (Azzollini, Azzara, Depaula, Cosentino, & Grinhauz, 2017; Farchi et al., 2018). It was applied Bases for Urgent Decisions under Extreme Circumstances Inventory (BUDECI; Cosentino, Azzollini, Depaula, & Castillo, 2017) to evaluate their decisive style. It was observed an inverse correlation and statistically significant between the effectiveness in the PFA (i.e., performance ISPFA) and the urgent affective´ decisive style (r = -.27; p = .04) in the trained group in PFA. It concludes that the emotional decisions in trained people operate in detriment of the best implementation in FPA. Key words Effectiveness - Psychological first aid - Decisive style - Rescue
