I am a huge fan of Craig Bryan. He, Sharon Stone, and David Rudd (another person whose work I really admire) have just published an article titled, "A Practical, Evidence-Based Approach for Means-Restriction Counseling With Suicidal Patients." I know I will be recommending this article a lot. Questions about means restriction come up just about every time I teach or consult with mental health professionals about managing suicide risk. This will be my go-to resource from now on. The authors carefully present the evidence for means restriction, and provide a clear and immediately useful guide for conducting means restriction counseling. Highly recommended:
A practical, evidence-based approach for means-restriction counseling with suicidal patients.
