Table 7 Eight Criteria used in Review II to Assess PtDAs and PtDA Trials: Their Definitions and Coding Values

From: Addressing health literacy in patient decision aids

  Criterion Tag and Definition Coding Value Notes
1 Lit Level Understood
Is the PtDA written at a level that can be understood by a majority of patients in the study sample? If no mention of measuring comprehension was made a “2” was assigned. A simple increase in knowledge by the subjects was not taken to mean they understood.
Yes = 1
No = 2
 
2 < Grade 9
Was the PtDA stated to be at grade 9 readability level or less?
Yes = 1
No = 2
Don’t know = 9
If yes, what measure?
3 Other than Text
Does the PtDA provide ways to help patients understand information other than by reading? Includes specifically audio, video, web-based or reading aloud by researcher.
Yes = 1
No = 2
Don’t know = 9
If yes, what medium/media?
4 Web-based
The web is understood to mean access by computer, either at home or some other location with access to the world wide web.
1 = web-based and not all text; 2 = not web-based; 3 = web-based and all text; 9 = web-based and couldn’t tell whether all text-based or not.
(If 2, then not web; if 1 or 3 or 9, then web-based.)
1 = multimedia web
2 = no web
3 = web text
9 = web but couldn’t tell content
 
5 Stratified by Literacy
Was the study sample stratified by literacy level?
Yes = 1
No = 2
Don’t know = 9
If surrogate measure, what?
6 Stratified by Education
Was the study sample stratified by education level?
Yes = 1
No = 2
Don’t know = 9
If surrogate measure, what?
7 Over –sampled Lower Literacy?
Did the study over-sample lower literacy populations?
Yes = 1
No = 2
Don’t know = 9
 
8 Literacy Conclusion?
Did the study draw literacy conclusions? (Code = 1 if any mention of literacy effects upon outcome variables, including if subgroup analyses were undertaken post-hoc)
Yes = 1
No = 2
Don’t know = 9
If yes, what?
