Validez y confiabilidad de la Escala de Percepción de Riesgo de Deslave en la Ciudad de México

The main objective of this study was to develop a valid and reliable scale that assessed the risk perception in urban settlements vulnerable to geological hazards in Mexico City. The scale included 9 items with 5 optional answers. In order to obtain optimum psychometric properties, the scale was applied to 217 inhabitants between the ages of 18 and 86, from which 126 were women and 91 men. The analysis of factorial structure and the reliability provide a final scale made up from 6 items organized in 2 factors with satisfactory goodness of fit (df = 8; χ2 = 14.138; P = .078; CFI = .990; RMSEA = .060). It is concluded that the Scale of Landslide Risk Perception provides relevant information for decision-making to extreme natural phenomena in Mexico City.
