Design and validation of infostructure maturity model survey through rasch techniques

Abstract

Disaster in Malaysia originated from either natural causes or manmade reasons. It can bring catastrophic impact to a nation, in terms of human, economic or environment. Disaster management essentially relies heavily on information where all agencies involved need to ensure proper information is being disseminated in the event of a disaster. Information is needed in ensuring an effective disaster relief efforts. Hence, this paper aims to design and validate an instrument which measures the infostructure used in disaster management from three dimensions, Coordination, Communication and Control, namely the 3Cs. The instrument validation involved three (3) stages: (i) content validity, (ii) expert validation, and (iii) pilot test using Rasch Model with winstep software. This study proved that twenty-two (22) respondents are balanced for responding to fifty-seven (57) items in Rasch measurement model. © 2005 – ongoing JATIT & LLS.
