Items are scored, for each respondent, according to the order of their mentioning (i.e.first mentioned EDI scores 1, second scores 2, third scores 3, and so on). The item importance weight is then given by its inverse order, therefore first mentioned items received higher scores: 1/1¼1.00; 1/2 ¼ 0.50, 1/3 ¼ 0.33 etc. Items from all interviews are reviewed and grouped to avoid replication due to how respondents may refer to the same EDI by different names.
