The availability of different scales measuring similar constructs challenges scientists and practitioners when it comes to choosing the most appropriate instrument to use. As a result, systematic comparison frameworks have been developed to guide such decisions. The Consensus-based Standard for the Selection of Health Measurement Instruments (COSMIN) is one example of such a framework to examine the quality of psychometric studies. This article aimed, firstly, to explore the psychometric characteristics of resilience measures used in the South African Navy (SAN), in that context. Secondly, it aimed to illustrate the application of the COSMIN guide for comparing psychometric scales and employing data from the aforementioned resilience measures, as a practical case study. The study drew on both published and unpublished data from seven SAN samples, using eight psychometric scales associated with resilience. It assessed structural validity, construct validity, internal reliability and predictive ability. The outcomes were tabulated, and the COSMIN criteria were applied to each data point. All eight scales provided some degree of evidence of validity. However, it was at times difficult to differentiate between the scales when using the COSMIN guidelines. In such cases, more nuanced criteria were necessary to demonstrate more clearly the differences between the psychometric characteristics of the scales and ease in subsequent decision-making.
This article illustrated the application of COSMIN guidelines to systematically compare the quality of psychometric study outcomes on local South African data. It further offered evidence of validity for a range of resilience-related measures in a South African context.
当涉及到选择最合适的工具时，存在不同的量表来测量相似的结构，这给科学家和从业者带来了挑战。因此，已经开发了系统的比较框架来指导此类决策。基于共识的健康测量工具选择标准（COSMIN）就是这样一个用于检验心理测量学研究质量的框架的例子。本文旨在，首先，在南非海军（SAN）的背景下探索复原力测量工具的心理测量学特征。其次，作为一个实际案例研究，说明应用COSMIN指南来比较心理测量量表并使用上述复原力测量工具的数据。该研究利用了来自七个南非海军样本的已发表和未发表的数据，使用了八个与复原力相关的心理测量量表。它评估了结构效度、构想效度、内部信度和预测能力。结果被制成表格，并将COSMIN标准应用于每个数据点。所有八个量表都提供了一定程度的效度证据。然而，在使用COSMIN指南时，有时很难区分这些量表。在这种情况下，需要更细微的标准来更清楚地展示量表心理测量学特征之间的差异，并便于后续决策。
本文说明了应用COSMIN指南来系统比较南非本地数据的心理测量学研究结果的质量。它还进一步提供了南非背景下一系列与复原力相关的测量工具的效度证据。
