Validating questionnaire design of infostructure maturity model for disaster management selected processes

Abstract

Disaster can affects a nation from functioning normally, and it can impact human, material, economic or environment. Disaster management is the concept being applied during disaster in organizing and managing resources and responsibilities of all relevant agencies in the event of disaster. Today, disaster management critically relies on information to ensure all agencies responsible can disseminate information in making a better and effective disaster relief efforts. Based on this motivation, we posit a maturity model that aim to identify the improvement of infostructure for disaster management. Maturity model is commonly used to guide the development of improvement program to transform to a better state, which in this research is to improve the infostructure being used during disaster. An initial conceptual maturity model has been constructed based on selected disaster processes. Based on the literature review, questionnaire items have been designed to form the identified latent constructs. A pilot survey has been conducted to verify the questionnaire items and the results are tested against Rasch measurement analysis. By using Rasch logit measures, the items' quality is ensured. Findings indicate that the item fitness is good, outfit and infit mean square values are very much close to 1, and Z-standardized value is within the expected range. Nonetheless, there are several misfit items which are further calibrated and revised for future study.
