Summary
Brief summary (as posted)
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.
