The coding procedure of these interviews was identical to and independent of the procedure of the physician interviews.
Moreover, the procedure of the clinical examination and personal interview was trained.
They were trained by the researcher to understand the objectives of the study and the purpose and procedure of the interview process; to have a common understanding of the questions in the interview schedule; and to ask the questions to the understanding of the respondents.
Minor adaptations to the instructions and procedure of the interview were made following the pilot study.
The researcher explained the purpose and procedure of the interview, then gave an information sheet with written explanation to the patient.
There were no differences between the two groups in socio-demographic characteristics or time between the end of the procedure and the interview (~24 minutes) (Table 1).
Immigrants with a good level of Greek language proficiency facilitated the procedure of interviewing as translators.
All key informants received written information about the purpose and procedure of the interviews.
The methodological quality of this case study could also be improved with more complete information on the designing, sampling, and implementation procedures of the interviews.
