NCT03672617

Brief Summary

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.

Study Arms (2)

Children and adolescents

Children and adolescents, who administer growth hormone (GH) themselves (self-injections) will be asked to complete the questionnaire.

Other: No treatment given

Parents/legal guardians

Parents/legal guardians who administer the GH to their child will be asked to complete the questionnaire.

Other: No treatment given

Interventions

No treatment is given to study participants. Only evaluation of a questionnaire assessing reasons for non-adherence to growth hormone therapy (GHT) and to determine its validity and reliability. The preliminary working title of the questionnaire GHCQ used in the outcome measures was renamed for simplicity reasons into BAR-GHT (abbreviation for barriers to growth hormone therapy) after study completion.
