Centro de Documentacion de Fundación MAPFRE - Inter-rater reliability of query-probe-based techniques for measuring situation awareness

Notas: Sumario: Query- or probe-based situation awareness (SA) measures sometimes rely on process experts to evaluate operator actions and system states when used in representative settings. This introduces variability of human judgement into the measurements that require inter-rater reliability assessment. However, the literature neglects inter-rater reliability of query/probe-based SA measures. We recruited process experts to provide reference keys to SA queries in trials of a full-scope nuclear power plant simulator experiment to investigate the inter-rater reliability of a query-based SA measure. The query-based SA measure demonstrated only moderate¿ inter-rater reliability even though the queries were seemingly direct. The level of agreement was significantly different across pairs of experts who had different levels of exposure to the experiment. The results caution that inter-rater reliability of query/probe-based techniques for measuring SA cannot be assumed in representative settings. Knowledge about the experiment as well as the domain is critical to forming reliable expert judgements.Registros relacionados: En: Ergonomics : the international journal of research and practice in human factors and ergonomics. - Oxon [United Kingdom] : Taylor & Francis, 2010- = ISSN 0014-0139. - 07/07/2014 Volumen 57 Número 7 - julio 2014 Otras clasificaciones: 875
