Note. NAP = non-overlap of all pairs; GAS = Goal Attainment Scaling; SE = standard error; BPI = Brief
Problem Inventory; NAP values for participant 1, GAS scores could not be calculated because too
many values were missing (87%).
Behavioural problems
The NAP values for the BPI total frequency and severity scores indicate that the
differences between A and B range from mainly weak effects to medium and
(one) large effects (see Table 6). Randomisation tests were not statistically
significant for the total frequency (observed Mdifference = 0.80, p = .407) and the
total severity of behavioural problems (observed Mdifference = 0.73, p = .367).
Involuntary care
For one participant, one extra case of predetermined (multidisciplinary)
involuntary care (off-label psychopharmacological medication) was
recorded by professional caregivers of the participant during the intervention
phase compared to the baseline. Another participant experienced one
incident of involuntary care, recorded by the professional caregiver, during
the follow-up phase. No other changes in recorded involuntary care
measures or incidents of involuntary care were recorded.
