The life attitude of health care workers can deeply influence the quality of care. Examining the performance of the Short-Form Life Attitude Inventory (SF-LAI), this study analyzes the factorial structure, reliability, and invariance of the revised SF-LAI across genders and professions among the staff of a teaching medical center.
The SF-LAI was developed for university students in Taiwan. From January to February 2019, we administered a cross-sectional survey of life attitudes by distributing the SF-LAI to all staff members of a medical center in Taiwan. The construct validity was evaluated using a confirmatory factor analysis (CFA). Model fit was assessed in terms of the comparative fit index (CFI), Tucker-Lewis index (TFI), standardized root mean square residual (SRMR), and root mean square of error of approximation (RMSEA). Internal consistency was calculated using Cronbach's alpha and McDonald's omega. We also performed the CFA invariance analysis for the SF-LAI-R across genders and professions (physician, nurse and other hospital staff).
Of 884 (24.62%) responses, 835 were valid. The participants had a mean age of 47.8 years, and 20.12% were male. In a comparison of multiple CFAs, a second-order model with six factors outperformed other models. The goodness of fit indices revealed the CFI was 0.955, TFI was 0.952, RMSEA was 0.071, and SRMR was 0.038. The Cronbach's alphas, McDonald's omega coefficients for internal consistency were all greater than 0.8. The first and second-order model had metric and scalar invariance across genders and professions.
As health care demands evolve, humanities are becoming more important in medical education. Life attitude of hospital care worker is a crucial indicator of whether one embodies the ideals of a humanistic education. The revised SF-LAI has acceptable structural validity, internal consistency, and invariance across genders and professions among staff members of a teaching medical center.
医护人员的生活态度会深刻影响护理质量。本研究采用短式生命态度量表（SF-LAI）评估医护人员的表现，分析经过修订的 SF-LAI 量表在某教学医院员工中的因子结构、信度和性别、职业不变性。
SF-LAI 最初为台湾地区大学生编制。2019 年 1-2 月，我们采用横断面调查的方式，向台湾某教学医院全体员工发放 SF-LAI 量表，评估生活态度的构念效度。采用验证性因子分析（CFA）评估模型拟合度。以比较拟合指数（CFI）、塔克-刘易斯指数（TFI）、标准化均方根残差（SRMR）和近似均方根误差（RMSEA）评估模型拟合度。采用克朗巴赫α系数和麦克唐纳ω系数评估内部一致性。我们还对 SF-LAI-R 进行了性别和职业（医师、护士和其他医院员工）不变性分析。
884 份（24.62%）有效回复中，有 835 份为有效问卷。参与者的平均年龄为 47.8 岁，20.12%为男性。在多个 CFA 的比较中，二阶六因子模型优于其他模型。拟合指标显示 CFI 为 0.955，TFI 为 0.952，RMSEA 为 0.071，SRMR 为 0.038。克朗巴赫α系数、麦克唐纳ω系数均大于 0.8，表明内部一致性较好。一阶和二阶模型在性别和职业方面具有度量不变性和标度不变性。
随着医疗需求的变化，人文学科在医学教育中变得越来越重要。医院护理人员的生活态度是其是否体现人文教育理想的重要指标。修订后的 SF-LAI 量表在教学医院员工中具有可接受的结构效度、内部一致性和性别、职业不变性。
