Sample
The study sample was comprised of 303 RNs in coronary
care units across 12 hospitals in Sweden. A coronary care
unit from each of the 12 hospitals participated in a study
linking patient involvement ratings with registry data for
cardiac patients (Arnetz et al. 2010). All RNs who worked
with MI patients on a regular basis were eligible for
participation. The number of nurses per unit ranged from
12–42 (M = 25?25, SD = 7?93). Demographic information
for study participants is presented in Table 1.
