Summary

The objective of this study is to translate the "AKQoL"-questionnaire which measures the quality of life of patients with actinic keratosis into German and to validate it for the Swiss population.

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.

Interventions

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.
