Project
Health-related questionnaires are used in many psychological studies and clinical trials. I know from my own experience that information about scoring procedures are often scattered among numerous sources and, thus, hard to find. Since I frequently work with questionnaires, I have decided to write "qscorer", an R package with scoring procedures for health-related questionnaires. https://scriptsandstatistics.wordpress.com/2019/04/30/scoring-questionnaires-unsing-the-qscorer-package/ https://nrkoehler.github.io/qscorer/

Project
The study examined psychological distress, quality of life and social support of cancer patients at the end of life and family caregivers in the course of ambulatory home care. Furthermore, the patient's physical symptoms and the exhaustion and overload of the caring relatives have been examined. Attitude of patients and relatives on euthanasia was an additional focus of the study. The project has a longitudinal study design, in which the cancer patients and their caring relatives were interviewed at home at different measuring times. The study - funded by the German Cancer Aid - was carried out from 2011 to 2014 at the Department of Medical Psychology and Medical Sociology, University of Leipzig.
