Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
By using the technique of cognitive interviewing the investigators are focussing on the patients' understanding of the questions. The first session of cognitive interviews will show, where there is need for improvement in terms of misinterpreted phrases or vaguely worded questions. The goal is to rephrase the questions according to the feedback of the patients. The revised version will then be presented to a new population.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The objective of this study is to translate this questionnaire into German and to validate it for the Swiss population. This questionnaire might become part of a planned national register for data collection of patients with AK.
The investigators will assess the content validity of the questionnaire by using the technique of cognitive interviewing. The investigators are going to talk 34 patients with AK from the department of Dermatology, University Hospital Zurich through the translated version. Thereby, the investigators are focusing on the patients' understanding of the questions.
The first session of cognitive interviews will show, where there is need for improvement in terms of misinterpreted phrases or vaguely worded questions. The goal is to rephrase the questions in the sense that they become more clear and are understood by different interviewee in the same way. The revised version will then be presented to a new population. The performance of cognitive interview sessions and revisions will continue until the survey will be approved by at least 80% of the respondents.

individual cognitive interviewing, 30 minutes per patient
cognitive interviewing
For the individual cognitive interviews we are using the two techniques "to think aloud" and the "verbal probing". "To think aloud" means, that the patients are asked to express precisely what comes to their mind when reading the single questions. This means, the interviewer is interested in the line of thoughts, which arise when reading the question. Thereby, the problems which appear in the usually covert process of answering a question should be revealed. In a second step, we are using the "verbal probing" technique to identify possible misunderstandings of the questions or difficulties with single phrases. The interviewer asks further questions that target the patients' interpretation.
