“…The concept of "nursing competency" was first clarified in an integrative review with three main components: "process," "essential/fundamental element," and "measurement." "Process" is an individual's growth from novice to expert, or their path from general to specialized thinking (Dudas, 2012;Suh, 2004); "essential/fundamental element" concerns the basics of the profession (Axley, 2008;Caruso, Fida, Sili, & Arrigoni, 2016;Garside & Nhemachena, 2013;Sarah, 2012); and "measurement" is an index of nursing abilities (Kulju, Stolt, Suhonen, & Leino-Kilpi, 2016;Laibhen, 2014;Scott Tilley, 2008). The concept of dementia nursing competency defined in previous studies as person-centred care includes applying evidenced-based approaches, recognizing dementia, improving communication and assessment skills, developing knowledge as a nursing specialist, and environmental management of patients and families (Dewing & Traynor, 2005;Fleming, Fay, & Robinson, 2012;Robinson et al, 2014;Traynor & Dewing, 2002;Traynor, Kumiyo, & Patrick, 2011).…”
