evidence: ixed-models for EPAS total score (see Table 3) indicated a significant effect of time (b = 0.07, p < 0.001), but no significant group by time interaction effect (b = 0.02; p = 0.258). This means with regard to the parameterisation of the mixed effects model that there was a significant change of overall empowerment in the control group, but NWpG-IC treatment had no additional effect on improvement of overall empowerment during the 18 month study period.
intervention: The Network for Mental Health (NWpG-IC)
comparator: standard mental health care
outcome: prevalence of psychiatric inpatient admission
