Objective The present study examined the usability and effectiveness of the Linehan Suicide Safety Net (LSSN), a web‐based, multimedia tool designed to support clinicians working with individuals who are suicidal. The core feature of LSSN is the Linehan Risk Assessment and Management Protocol (LRAMP), an empirically derived protocol that provides a structured checklist for assessing, managing, and documenting suicide risk. Method Mental health professionals (N = 44) completed assessments at baseline and monthly during a 3‐month evaluation period. Results The LSSN was rated as acceptable and highly usable. Use of the LSSN was associated with a significant increase in confidence in conducting suicide risk assessment and management and a decrease in concerns related to treating suicidal clients. Conclusion The LSSN appears to be a promising tool for clinicians working with suicidal clients.
