Table 2 Top-down operationalization

From: Patient decision aids: a content analysis based on a decision tree structure

Criteria Definition
Decision tree
 Incomplete knowledge acknowledged Does the PDA include acknowledgement of decision nodes with incomplete information? Does it emphasize the areas where knowledge is incomplete
 Missing structure 1 and 2 Does the tool investigate all logical branches of the decision tree? If not, describe missing structure.
 Pros and Cons logic Does the “pros and cons” list miss any logical branches of the decision tree? If yes, describe missing structure.
Decision process
 Overall strategy in Personal Stories (P.S) Do the stories reflect an overall strategy for choosing treatments? E.g. “Try out anything”, “Choose only treatments with less side-effects”, etc.?
 Biased stories Does the Personal Stories Section include more reports of one treatment option than the other
 Decision-aid type Description of the structure of the decision-making process in terms of steps taken to reach a decision
 Shared Decision PDA contains elements that allow taking into consideration the opinions of other parties (family members, significant others)
 Surrogate awareness In case the text is used by surrogate decision makers, does the PDA include reference or suggestion to consider the values of dependent patients (older patients, low literacy patients, children, etc.) and not just those of the surrogate
 Logically ambiguous phrasing Does the PDA include sentences or statements which may be misleading or ambiguously phrased. If yes, include phrase.
