BACKGROUND
Assessment of the patient safety competency is necessary for the growth of nursing and safe care profession as well as evaluation of the nurses' educational needs. The present study was conducted to determine psychometric properties of the Persian version of the patient safety competency self-evaluation (PSCSE) tool in Iranian psychiatric wards.
MATERIALS AND METHODS
All nurses ( = 209) working in two psychiatric hospitals of Kerman, Iran, were included in the present cross-sectional study using census method. This tool contains 41 items: six items are related to knowledge, 14 items deal with attitude, and 21 items are about skill dimension. Psychometric properties of the questionnaire including its content and face validity were also examined. The factor structure of the questionnaire was evaluated using exploratory factor analysis. The internal consistency and reliability were assessed by test-retest method with an interval of 14 days. Cronbach's alpha and corrected item-total correlation were used to measure reliability.
RESULTS
The content validity index was 0.65 and the content validity ratio was 0.89. Item 14 was removed from the skill domain because it was not related to the psychiatric ward. According to the results of factor analysis, there was a significant relationship between the questions and the relevant factors. The correlation coefficient for test-retest with 14 days interval was intraclass correlation coefficient = 0.92 for the whole instrument and 0.89, 0.89, and 0.92 for the domains of knowledge, attitude, and skill, respectively. The internal consistency coefficient (Cronbach's alpha) of the whole tool was 0.95 and 0.95, 0.79, and 0.95 for the domains of knowledge, attitude, and skill, respectively. Finally, PSCSE Questionnaire was obtained with 40 items in dimensions of knowledge (6 items), attitude (14 items), and skills (20 items).
CONCLUSION
Persian version of the nurses' competency tool in ensuring patient safety in psychiatric wards has acceptable psychometric characteristics.
背景
评估患者安全能力对于护理和安全护理专业的发展以及评估护士的教育需求至关重要。本研究旨在确定伊朗精神病病房中患者安全能力自我评估（PSCSE）工具波斯语版本的心理测量特性。
材料与方法
本横断面研究采用普查法，纳入了伊朗克尔曼两家精神病医院的所有护士（n = 209）。该工具包含41个项目：6个项目与知识相关，14个项目涉及态度，21个项目关于技能维度。还检查了问卷的心理测量特性，包括其内容和表面效度。使用探索性因子分析评估问卷的因子结构。通过间隔14天的重测法评估内部一致性和可靠性。使用Cronbach's alpha和校正的项目 - 总分相关性来测量可靠性。
结果
内容效度指数为0.65，内容效度比为0.89。由于项目14与精神病病房无关，因此从技能领域中删除。根据因子分析结果，问题与相关因子之间存在显著关系。间隔14天的重测相关系数，整个工具的组内相关系数为0.92，知识、态度和技能领域分别为0.89、0.89和0.92。整个工具的内部一致性系数（Cronbach's alpha）为0.95，知识、态度和技能领域分别为0.95、0.79和0.95。最后，获得了PSCSE问卷，在知识（6项）、态度（14项）和技能（20项）维度上共40个项目。
结论
波斯语版本的护士能力工具在确保精神病病房患者安全方面具有可接受的心理测量特征。
