process and generated information were structured according to the four stages of the response process as described by Tourangeau [18]. Problems within the response process and information not corresponding to the purpose of the PSC were identified, labeled and added to the earlier mentioned coding scheme as part of the concept of ‘perceived ease of use’.
As a last step researcher MW compared the analyzed interviews of Dutch and Turkish respondents as well as low, moderately and highly educated respondents, respondents with adequate and low health literacy and respondents who were and were not able to complete the PSC independently. By comparing the codes within and between the groups she looked for possible different patterns in relation to perceived ease of use, problems in the response process, generated information and perceived usefulness. Again this step was repeatedly checked by and discussed with researchers HW and MJW.
