To develop the Psychiatric Nurse Self-Efficacy Scales, and to examine their reliability and validity.
We developed the Improved Self-Efficacy Scale (ISES) and Decreased Self-Efficacy Scale (DSES) using existing evidence. Statistical analysis was conducted on the data to test reliability and validity.
The study's setting was psychiatric facilities in three prefectures in Japan.
Data from 514 valid responses were extracted of the 786 responses by psychiatric nurses.
The study measured the reliability and validity of the scales.
The ISES has two factors ('Positive changes in the patient' and 'Prospect of continuing in psychiatric nursing') and the DSES has three ('Devaluation of own role as a psychiatric nurse', 'Decrease in nursing ability due to overload' and 'Difficulty in seeing any results in psychiatric nursing'). With regard to scale reliability, the Cronbach's alpha coefficient was 0.634-0.845. With regard to scale validity, as the factorial validity of the ISES and DSES, for the ISES, χ/df (110.625/37) ratio=2.990 (p<0.001), goodness-of-fit index (GFI)=0.962, adjusted GFI (AGFI)=0.932, comparative fit index (CFI)=0.967 and root mean square error of approximation (RMSEA)=0.062; for the DSES, χ/df (101.982/37) ratio=2.756 (p<0.001), GFI=0.966, AGFI=0.940, CFI=0.943, RMSEA=0.059 and Akaike Information Criterion=159.982. The concurrent validity of the General Self-Efficacy Scale was r=0.149-0.446 (p<0.01) for ISES and r=-0.154 to -0.462 (p<0.01) for DSES, and the concurrent validity of the Stress Reaction Scale was r=-0.128 to 0.168 for ISES, r=0.214-0.398 for DSES (p<0.01).Statistical analyses showed the scales to be reliable and valid measures.
The ISES and DSES can accurately assess psychiatric nurses' self-efficacy. Using these scales, it is possible to formulate programmes for improving psychiatric nurses' feelings of self-efficacy.
编制精神科护士自我效能量表，并检验其信度和效度。
采用现有证据编制改良自我效能量表（ISES）和降低自我效能量表（DSES）。对数据进行统计分析以检验信度和效度。
该研究的设置是日本三个县的精神科设施。
从精神科护士的 786 份有效回复中提取了 514 份有效回复的数据。
该研究衡量了量表的信度和效度。
ISES 有两个因素（“患者积极变化”和“继续从事精神科护理的前景”），DSES 有三个因素（“贬低自己作为精神科护士的角色”、“因超负荷而降低护理能力”和“在精神科护理中难以看到任何结果”）。关于量表的信度，克朗巴赫的阿尔法系数为 0.634-0.845。关于量表的效度，作为 ISES 和 DSES 的因子有效性，对于 ISES，χ/df（110.625/37）比=2.990（p<0.001），拟合优度指数（GFI）=0.962，调整拟合优度指数（AGFI）=0.932，比较拟合指数（CFI）=0.967，近似均方根误差（RMSEA）=0.062；对于 DSES，χ/df（101.982/37）比=2.756（p<0.001），GFI=0.966，AGFI=0.940，CFI=0.943，RMSEA=0.059，Akaike 信息准则=159.982。一般自我效能感量表的同时效度为 ISES 的 r=0.149-0.446（p<0.01）和 DSES 的 r=-0.154-0.462（p<0.01），应激反应量表的同时效度为 ISES 的 r=-0.128-0.168，DSES 的 r=0.214-0.398（p<0.01）。统计分析表明这些量表是可靠和有效的测量工具。
ISES 和 DSES 可以准确评估精神科护士的自我效能感。使用这些量表，可以制定提高精神科护士自我效能感的方案。
