Validation of the Impact of Event Scale‐Revised for adolescents experiencing the floods and mudslides

Abstract

The purpose of this study was to validate the Impact of Event Scale-Revised (IES-R) for adolescents who had experienced the floods and mudslides caused by Typhoon Morakot in Taiwan. The internal consistency, construct validity, and criteria validity of the instrument were examined. Principal component analysis followed by an oblique rotation was used to derive a three-factor solution. These factors were labeled intrusion, hyperarousal, and avoidance; all three factors together accounted for 58.1% of the variance. The total Cronbach's alpha of 0.94 reflected the good internal consistency of the instrument. With reference to diagnosis of posttraumatic stress disorder, the IES-R cutoff point for posttraumatic stress disorder was 19 of 20 with a sensitivity of 85.7% and specificity of 84.1%. In conclusion, the IES-R can be used as a reliable and valid instrument when evaluating psychological distress among adolescents who have experienced a natural disaster, such as flooding and mudslides.

Diagnostic accuracy of Japanese posttraumatic stress measures after a complex disaster: The Fukushima Health Management Survey

“…Cronbach alphas for the subscales are 0.86 to 0.91 for intrusion, 0.81 to 0.90 for avoidance, and 0.80 to 0.86 for hyperarousal (Weiss, 2004). Although the IES-R was not developed for making categorical PTSD diagnosis, various cutoff points have been proposed to indicate probable PTSD, with a range from 19 to 35 (Asukai et al, 2002;Bienvenu, Williams, Yang, Hopkins, & Needham, 2013;Chen, Cheng, & Yen, 2011;Creamer, Bell, & Failla, 2003).…”

Estrés Post-Traumático Y Estrés Subjetivo en Estudiantes Universitarios Tras Aluvión De Barro

“…El instrumento se ha utilizado en diversas investigaciones respecto del impacto a desastres y emergencias (Arcaya et al, 2014;Brunet, St-Hilaire, Jehel, & King, 2003;Caamaño, González, & Sepúlveda, 2011;Creamer, Bell, & Failla, 2003;Giorgi et al, West, & Usher, 2015). incluyendo aluviones de barro (Cheng-Sheng, et al, 2011;Craparo et al, 2013); sus propiedades psicométricas han sido evaluadas en China arrojando valores adecuados (Wu, & Chan, 2004). Además presenta un 72% de sensibilidad para la detección de TEPT en relación a otros instrumentos psicométricos similares (Mouthaan, Sijbrandij, Reitsma, Gersons, & Olff , 2014).…”

“…Ante este tipo de catástrofe se ha visualizado a la hiperactivación autonómica como el síntoma de mayor prevalencia (Craparo, Faraci, Rotondo, & Gori, 2013). En otro estudio, en Taiwán, luego del tifón y aluvión Morakot -8 de agosto del 2009se encontró un 25.8% de TEPT, particularmente representado por pensamientos intrusivos, hiperactivación fi siológica y psicológica y evitación (Cheng-Sheng et al, 2011). Un dato de especial preocupación es la alta prevalencia de TEPT (25.8%) encontrada ante este tipo de desastre, en jóvenes víctimas a 3 meses de un aluvión por el efecto de la sintomatología ansiosa de tipo irruptiva e intrusiva en el desarrollo cognitivo (Pinchen et al, 2011).…”

“…Based on the analysis of existing neural networks (Eisenbies et al 2007;Kong-A-Siou et al 2013;Liu et al 2014a), early warning (Krzhizhanovskaya et al 2011;Alfieri et al 2012;Borga et al 2014;Van Veen 2014), fuzzy (Royston et al 2013) expert (Karnib et al 2002;Kou et al 2014) and decision support (Hubbard et al 2014) systems, Impact of Event Scale (Shooshtary et al 2008;Heir et al 2010;Chen et al 2011;Dancause et al 2011;Keskinen-Rosenqvist et al 2011;Arnberg et al 2014, Kaklauskas 1999Kaklauskas et al 2010;2011 etc. ) and in order to determine most efficient tips of stress resilience a Physiological Advisory Subsystem to Analyse a User's Post-Disaster Stress Management consisting of an equipment subsystem, database, database management subsystem, model-base, model-base management subsystem and user interface was developed (see Figure 3.1).…”
