Samenvatting

PURPOSE: To test if a collaborative care program (CCP) with nurses in a coordinating position is beneficial for patients with severe personality disorders.
DESIGN AND METHODS: A pilot study with a comparative multiple case study design using mixed methods investigating active ingredients and preliminary
results.
FINDINGS: Most patients, their informal caregivers, and nurses value (parts of) the CCP positively; preliminary results show a significant decrease in severity of borderline
symptoms.
PRACTICE IMPLICATIONS: With the CCP,we may expand the supply of available treatments for patients with (severe) personality disorders, but a larger randomized
controlled trial is warranted to confirmour preliminary results.
