目的:分析巴西初级保健患者报告经验和安全性结果(PREOS-PC)紧凑型表格的跨文化改编版本的心理测量特性。
方法:对281名成人初级卫生保健使用者进行了方法学研究。数据收集是在网上进行的。验证性因素分析(CFA)用于评估PREOS-PC在跨文化适应巴西环境后的心理测量特性。通过Cronbach的α系数(α)和McDonald的ω系数(ω)评估内部一致性。
结果:样本由73.3%的女性组成。平均年龄为36.1岁(SD=12.2)。在获得CFA资格的PREOS-PC的23个项目中,具有四个相关域和16个项目的模型具有令人满意的拟合指数。这些领域是实践激活(PrA)(四个项目),患者激活(PaA)(两项),患者安全事件(EPaS)经验(五项)和患者安全结局(OPaS)(六项)。一个领域(GPeS)提出了一个问题,回答量表为0到10,两个开放性问题,由于项目的性质,无法插入CPA中,但可以包括在量表的应用中,单独评估。在这个阶乘模型中,五个项目(EPAS2、EPAS3、EPAS4、EPAS5、EPAS6和EPAS8)呈现因子载荷≤0.30。对于PREOS-PC的所有域,α和ω值表现出良好的内部一致性。
结论:由四个域组成的PREOS-PC紧凑型巴西版本(PrA,PA,EPaS和OPaS)和16个项目提供了验证其心理测量特性的证据,可用于评估巴西背景下初级卫生保健中患者安全的经验和结果。
OBJECTIVE: To analyze the psychometric properties of the cross-culturally adapted version of the Patient Reported Experiences and Outcomes of Safety in Primary Care (PREOS-PC) Compact Form Brazil.
METHODS: A methodological study was conducted with 281 adult Primary Health Care users. Data collection took place online. Confirmatory Factor Analysis (CFA) was used to evaluate the psychometric properties of the PREOS-PC after the process of cross-cultural adaptation to the Brazilian context. Internal consistency was evaluated through Cronbach\'s alpha coefficient (α) and McDonald\'s omega coefficient (ω).
RESULTS: The sample consisted of 73.3% women. The mean age was 36.1 years (SD = 12.2). Of the 23 items of the PREOS-PC that were eligible for CFA, a model with four correlated domains and 16 items presented satisfactory fit indexes. The domains were Practice Activation (PrA) (four items), Patient Activation (PaA) (two items), Experiences of patient safety events (EPaS) (five items) and Outcomes of patient safety (OPaS) (six items). One domain (GPeS) presented one question with a 0 to 10 response scale and two open questions, which cannot be inserted in the CPA due to the nature of the items, but can be included in the application of the scale, being evaluated individually. In this factorial model, five items (EPaS2, EPaS3, EPaS4, EPaS5, EPaS6 and EPaS8) presented factor loadings ≤ 0.30. The α and ω values demonstrated good internal consistency for all domains of the PREOS-PC.
CONCLUSIONS: The Brazilian version of the PREOS-PC Compact Form Brazil composed of four domains (PrA, PA, EPaS and OPaS) and 16 items presented evidence of validation of its psychometric properties and can be used to evaluate the experiences and results of patient safety in Primary Health Care in the Brazilian context.
