Nursing science, health sciences, and the emerging sciences of the therapeutic and healing professions require ethical standards as quality characteristics, along with knowledge about the legal aspects of research, such as data protection law and care law. This book serves as a workbook, providing researchers with guidance and concrete advice on which research ethical principles, data protection regulations (Germany, Switzerland, Austria), and guidelines to follow when dealing with ethics committees. Methodologically, the examples cover areas including expert interviews, patients, video recording observations, randomized trials, relatives, caring for children, people with dementia, early rehabilitation, food refusal, self-injury, DCM, ambulatory care, family care, and persistent vegetative state. This is the second fully revised and expanded edition.
