“…This research was mainly conducted in Europe (n = 26) (34, 37, 39–43, 45, 46, 48–50, 52, 55, 57, 62, 63, 65–72, 74); 69% (n = 18) of the European studies were conducted in Sweden (34, 37, 39, 41, 42, 45, 46, 48, 49, 52, 55, 57, 66, 67, 69–72). The remaining studies were conducted in Australia (n = 8) (47, 51, 54, 58–60, 64, 75), North America (n = 5) (33, 38, 53, 61, 76), Asia (n = 3) (44, 73, 77) and the United Kingdom (n = 1) (56) (See Table 3). Samples consisted of patients (n = 17) (41, 45–47, 49, 51, 53, 55, 56, 61, 62, 64, 65, 67–69, 76), nurses (n = 15) (33, 34, 37, 39, 40, 43, 50, 52, 57, 60, 70–73, 75), or patients and nurses (n = 11) (38, 42, 44, 48, 54, 58, 59, 63, 66, 74, 77), and an ‘a theoretical’ approach was undertaken in 86% (n = 37) of studies (33, 34, 37–48, 51, 53–61, 63, 64, 66, 67, 69–77).…”
