Kokkuvõte	A household disaster preparedness scale measures the extent to which households have adopted actions that reduce their vulnerability to hazards — what the disaster literature calls hazard adjustments. Grounded in Michael Lindell and David Whitney's work on the correlates of seismic hazard adjustment adoption and connected to the broader Protective Action Decision Model, the scale assembles a set of concrete preparedness items — structural measures, survival supplies, and planning actions — and scores how many a household has taken. Beyond producing a preparedness index, the method models what predicts adoption, and a central, robust finding is that households' perceptions of the attributes of each adjustment (its efficacy, cost, time, and difficulty) predict adoption more strongly than fear or risk perception alone. The scale thus serves both to quantify preparedness and to explain why some households prepare while others do not.	The Community Disaster Resilience Index (CDRI) is a survey-based, multi-level composite-index method for assessing the resilience of communities to disasters, developed in the action-oriented form by Jonas Joerin, Rajib Shaw, Yukiko Takeuchi, and Ramasamy Krishnamurthy and applied in Chennai, India. CDRI decomposes resilience into a hierarchy: a small set of dimensions (commonly physical, social, economic, institutional, and natural), each split into parameters, each measured by several variables scored on a Likert scale. Variables are combined into parameter scores, parameters into dimension scores, and dimensions into an overall index, with weights typically elicited from stakeholders or experts. Unlike secondary-data indices, CDRI is built to be participatory and diagnostic — its purpose is to reveal which dimension of resilience is weakest in a given community so that action can be targeted there.
