Hazard Identification Responses

	Hazard state
HH-VSTS group (n = 38)	Hazard	Nonhazard
Identified as a hazard	98.1%	52.4%
	Hit	False positive
Identified as a non-hazard	1.9%	47.6%
	Miss	Correct rejection
Paper-based training group (n = 36)
Identified as a hazard	96.4%	39.5%
	Hit	False positive
Identified as a nonhazard	3.6%	60.5%
	Miss	Correct rejection

Note: Differences between the HH-VSTS and paper-based training groups regarding hazard identification considered only the hazards selected by participants. For example, if a hazard such as “water on the floor in the kitchen” was not selected as a possible hazard, it was not considered in any analysis. This allowed us to determine the accuracy of participants' ability to indicate if an item they identified in the home was/was not a hazard. Thus, each participant had a unique number of hazards identified. The percentage correctly identified was based on the number of potential hazards identified. Similarly, only the “What makes this a hazard?” and “What to do about the hazard?” possible response options for hazards identified were considered. If a participant did not identify the “water on the floor” as a hazard, they were not able to respond to the “What makes this a hazard?” and “What to do” dialog boxes, therefore, each participant also had a unique score for the “What makes this a hazard” and “What to do” items, and the unit of analysis was the percentage correct/incorrect based on the total possible correct responses.
