AIM
The aim of this study was to evaluate the construct validity and internal consistency of the revised Mental Health Literacy Scale (MHLS) in South Africa (SA) and Zambia.
DESIGN
This cross-sectional study was conducted between October 2018 and December 2019.
METHODS
The study population comprised PHC workers (n = 454) in five districts in SA and Zambia. Principal component analysis (PCA) was used to explore the construct validity, and Cronbach's alpha was applied to measure the internal consistency of the MHLS.
RESULTS
Cronbach's alpha values for three attributes were below the appropriate level, but the value was strong (0.804) for the whole scale. The study found nine components explaining ~59% of the total variance of variables. All MHLS items loaded to main attributes based on the theory of MHL. The results stated that the revised version of the MHLS is a construct valid instrument with strong internal consistency.
目的
本研究旨在评估修订后的心理健康素养量表（MHLS）在南非（SA）和赞比亚的结构效度和内部一致性。
设计
本横断面研究于 2018 年 10 月至 2019 年 12 月进行。
方法
研究人群包括来自 SA 和赞比亚五个地区的初级卫生保健工作者（n=454）。主成分分析（PCA）用于探索结构效度，Cronbach's alpha 用于测量 MHLS 的内部一致性。
结果
三个属性的 Cronbach's alpha 值低于适当水平，但整个量表的数值较强（0.804）。研究发现，九个成分解释了变量总方差的~59%。所有 MHLS 项目均根据 MHL 理论加载到主要属性。结果表明，修订后的 MHLS 是一种具有较强内部一致性的结构有效工具。
