The aim of the study is to examine the suitability, the so-called validation, of a questionnaire, with which one can grasp the reasons why injections of growth hormones are omitted by patients ("non-adherence"). Participants are treated with growth hormone and are therefore eligible to take part in the study. Study doctor will ask participants to answer questionnaires. two times within 14 days. The first time participants answer during the routine visit to the practice / clinic and the second time at home. There are no risks associated with participating in the study as it does not affect participant's medical treatment.
