Data on treatment experiences were provided from a 10-item
risk assessment inventory of patients’ past experiences. The
10 items on this inventory were drawn from the literature on
variables related to suicide attempts of patients with schizophrenia
(Potkin et al. 2003, Ran et al. 2007, Simms et al.
2007, Novick et al. 2010). These 10 items were assessed in
interviews with patients or their caregivers (five items) and
retrieved from official NHI records (five items). To assess
patients’ past experiences, community-based nurses asked
patients or their caregivers five simple questions about suicide-related
and treatment experiences during the previous
year.
