Table 1 Development of discrete choice experiments

From: Application of discrete choice experiments to estimate value of life: a national study protocol in Iran

Attributes and levels Identifications (potential attributes)
 Literature Review: To investigate the attributes that are likely to be important to users
Selecting the essential attributes (removing the inappropriate attributes): expert interviews (experts panel)
Experimental design
 Create proper tasks (choice sets): Orthogonal Fractional Factorial/ Blocking/ Imposed restrictions
Instrument design/data collection
 To estimate WTP and value the risk reduction, a larger survey instruments will be needed: face to face structured administrated survey
Statistical analysis
 Statistical analysis of data with logit model
