Please refer to the manuscript for a complete description of the methods for participant selection, data collection, and analysis.
In brief, the data were collected in eight focus groups. Each group developed a Bayesian Belief Network, and then individual participants in the focus groups completed conditional probability tables for four of the nodes in the network. Networks were constrained to one primary node, three secondary nodes, and three tertiary nodes for each secondary node, totaling 13 nodes. Nodes were constrained to two states; one described a positive or desirable outcome, and one a negative or undesirable outcome. In each group, a conditional probability table was developed for the primary node based on the states of the secondary nodes, and for each of the secondary nodes based on the states of the adjoining tertiary nodes. The conditional probability table presented eight possible scenarios (in other words, combinations of secondary or tertiary node states that were read as a hypothetical scenario to the participants) in each case, so each focus group participant assigned probabilities of positive outcomes for the subject node to 32 scenarios for their group's Bayesian Belief Network. The data provided here were taken from those conditional probability tables, so that other researchers can reconstruct and analyze the Bayesian Belief Network for each group. In the data, individual participants are identified by a numeric code to protect their identities, and each row in the data represents one scenario, so there are 32 rows of data (four eight-scenario conditional probability tables) for each participant.
In order to analyze the data in Netica, a blank row will need to be added at the top of each data sheet, with the following script pasted in the first cell (A1):
