Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The main parameter in this study is the number of aggression incidents in each arm as registered with the Staff Observation Aggression Scale-revised (SOAS-R, Nijman et al., 1999). As incidents differ in severity and consequences, they will be divided in major and minor incidents, major incidents are: severe threats, fighting, assault on patients or staff, self-harm, suicide attempt ; minor incidents are: verbal aggression, threats, non-compliance with hospital rules, aggression towards objects, disinhibited [sexual] behaviour. In our pilot study in institutions for long-term psychiatric inpatient care (Hazewinkel et al., in preparation) we monitored the time spent by nursing staff on each of these four types of incidents; verbal aggression took 80 minutes, aggression towards objects cost 77 minutes, self-harm cost 222 minutes, and physical aggression towards others cost 335 minutes per incidents. Based on these results, major incidents will be weighted by a factor 3.8. | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary parameters are: * facilitators and barriers of nutritional supplement acceptation by long-stay psychiatric inpatients (see J) * costs of time spent by staff members on aggression incidents and additional costs of incidents * patient quality of life as measured with the WHOQL-bref * patient self-report aggression levels as measured with the AVL-AV * patient observer rated affective symptoms as measured with the vCPRS * patient observer rated aggression levels as measured with the SDAS | — |
