Randomisation
Randomisation will take place at the team level, to avoid contamination between the intervention and control groups. Before the inclusion of clients, participating teams will be randomly assigned to the GILL eHealth intervention or the control group providing care as usual. This procedure will be performed by a statistician blinded to the characteristics of the teams using a computer-generated list of numbers. To optimise comparability of the subgroups, treatment settings (FACT, assisted housing, long-stay wards) will be matched before randomisation. Blinding of clients and participating teams is not possible due to the nature of the intervention.
