Involuntary care is a feature of mental health services around the world. In addition to involuntary admission and treatment, specific coercive practices include seclusion and physical restraint. Our study aimed to determine the relationships, if any, between these practices and perceived coercion on admission among psychiatry inpatients in Ireland, as well as any relationships between perceived coercion on admission and variables such as age, gender and diagnosis. We included 107 psychiatry inpatients aged 18 years or over who were admitted to the acute psychiatry admission units in Tallaght University Hospital and Connolly Hospital, Dublin, Ireland over a 30-month period between September 2017 and February 2020. Over a quarter (27.1%) of participating patients had involuntary status; nine (8.4%) had experienced at least one episode of seclusion, and ten (9.3%) had experienced at least one episode of restraint. Perceived coercion on admission was significantly associated with involuntary status and female gender; perceived negative pressures on admission were significantly associated with involuntary status and positive symptoms of schizophrenia; perceived procedural injustice on admission was significantly associated with fewer negative symptoms, involuntary status, cognitive impairment and female gender; and negative affective reactions to hospitalisation on admission were significantly associated with birth in Ireland and being employed. Total score across these four subscales was significantly associated with involuntary status and positive symptoms, and had borderline significant associations with birth in Ireland, being employed and female gender. Overall, perceived coercion on admission, assessed in retrospect by the patient, is more closely associated with involuntary status and symptoms than it is with subsequent formal coercive practices, such as seclusion and restraint. The role of gender merits particular attention in future research, especially in relation to procedural injustice on admission and perceived coercion on admission.

非自愿护理是世界各地精神卫生服务的一个特点。除了非自愿入院和治疗外，具体的强制措施还包括隔离和身体约束。我们的研究旨在确定这些做法与爱尔兰精神病院住院患者在入院时所感知的胁迫之间的关系（如果有的话），以及入院时所感知的胁迫与年龄、性别和诊断等变量之间的任何关系。我们纳入了 107 名 18 岁或以上的精神病住院患者，他们在 2017 年 9 月至 2020 年 2 月的 30 个月内住进了爱尔兰都柏林 Tallaght 大学医院和康诺利医院的急性精神病科住院部。超过四分之一 (27.1%)参与的患者处于非自愿状态；九人（8.4%）至少经历过一次隐居，10 人（9.3%）至少经历过一次克制。入院时感知到的胁迫与非自愿状态和女性性别显着相关；入院时感知到的负压与精神分裂症的非自愿状态和阳性症状显着相关；入院时感知到的程序不公正与较少的阴性症状、非自愿状态、认知障碍和女性显着相关；入院时对住院的负面情感反应与在爱尔兰出生和就业显着相关。这四个分量表的总分与非自愿状态和阳性症状显着相关，并且与爱尔兰的出生、就业和女性性别具有临界显着关联。总体，患者回想起来，在入院时感知到的胁迫与非自愿状态和症状的关系比与随后的正式胁迫行为（例如隔离和约束）更密切相关。在未来的研究中，性别的作用值得特别关注，尤其是在录取过程中的程序不公正和在录取时感知到的胁迫方面。
