Methods: We used focus groups and individual cognitive response interviews (CRIs) to develop an educational booklet for low literacy patients with heart failure.
Cognitive response interviews were not conducted.
Ten cognitive response interviews were conducted with patients with diabetes to assess each item.
The items of the DNT were developed by an expert panel and refined using cognitive response interviews with potential respondents.
This inconsistency may be due to the difference in speech samples used; we used only the free-response interview data, while Mundt et al. used a variety of speech samples including the free-response, a read passage, counting from 1 to 20, and reciting of the alphabet.
By computing the measures in this study from the free-response interview section of the recordings, instead of the read-passage recordings, we focus more on the changes in conversational speech and remove the variable of different reading styles used by the patients.
Key issues in data quality are the ability of survey questions to garner valid responses, interview length, response rates, and sampling issues (4).
The homework responses and interview responses have the same median and similar distributions.
Data were collected through 'structured open-response interviews' ([King 1994]) which fall between a structured questionnaire with closed questions, and ethnographic interviews with a very low degree of structure imposed by the interviewers.
The final selection of the schools in the pilot has been done based on the analysis of the questionnaire's responses, interviews with interested teachers, and on-site visits that were also performed.
After patients completed the questionnaire, the dietitian reviewed the answers and in the case of questionable responses interviewed the patient.
