ASSIP is a brief therapy for patients in treatment after a suicide attempt. It is administered as add-on therapy to usual clinical management. ASSIP is based on a patient-centered model of suicidal behavior, with a strong emphasis on therapeutic alliance. The therapy protocol is highly structured and consists of three face-to-face sessions, followed by regular letters sent to patients.
In a Randomized Controlled Trial with 120 participants (2016), ASSIP was highly effective in reducing suicide reattempts over 24 months follow-up. The risk of reattempting suicide in the ASSIP group was reduced by 80%. Furthermore, ASSIP participants spent 72% fewer days in the hospital during follow-up.
A cost-effectiveness study at the London School of Economics LSE (2018), based on the data of the RCT, found ASSIP to be dominant, with a 96% chance of being less costly and more effective than a psychosocial assessment, when added to usual clinical management.
