Patient Safety Culture programmes

CTT has been the dominant approach in psychometric theory for the past 100 years. Although IRT has been aroimd since the late 1960s (Lord and Novick 1968), until computer programmes were accessible to researchers it was not widely adopted. Its use is now reported in various literatures including healthcare (Chan et al. 2004), education (Kane 1987) and clinical psychology (Cooke and Michie 1997), to name a few. It is important, then, to pursue using such an approach in the field of assessment of patient safety culture as this technology becomes an expected standard in psychometric evaluation.
