This article looks at the relevance of the concept of self-determinati
on to psychiatric patients by studying the existence, importance and m
anifestations of self-determination. The data were collected by interv
iewing long-term patients (n = 72) in one mental health care organizat
ion, which included a psychiatric hospital and an outpatient departmen
t. Self-determination was defined in terms of the right to decision-ma
king, the right to information, the right of consent, the right to ref
use treatment, and the right to be heard and taken into account. It wa
s found that, with the exception of the right to refuse and consent, t
hese rights are indeed present in the practice of psychiatric nursing
and that they are relevant and important to psychiatric patients. The
patients typically gave ethical, practical and legal reasons for a psy
chiatric patients right to self-determination. The main reasons why ps
ychiatric patients said they lacked the right to self-determination we
re illness and-staff authority. Recommendations for educational, clini
cal and methodological implications for the future in nursing are disc
ussed.
