Data analysis: Quantitative data The main study question is whether the intervention is associated with a change in the degree of empowerment experienced by persons who receive hospital care due to psychosis. The secondary outcome measure is patient satisfaction at discharge. Quantitative ratings before and after the care intervention will be compared with standard statistical methods. Similarly, for the ward level analyses, wardwide outcomes will be compared in wards before and after the implementation of the intervention: mean number of inpatient days, mean number of inpatient days with compulsory care, mean number of involuntary treatment interventions and overall ward burden. Distribution of the variables to be studied will determine whether parametric or non-parametric analyses are employed.
