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