One of our most effective and well studied treatments in psychology is behavioral parent training (BPT), which can be used across many ages and types of problems.

But did you know most of them - such as COPE, Incredible Years, Defiant Child, PCIT, and more - are due to the work and influence of Dr. Constance Hanf, worked at the University of Oregon during the 1960s and 1970s and mentored the developers of those programs?

Hanf is one of the unsung heroes of child clinical psychology, and you can learn more at the link in the comments!

This is coming up, and I'm very excited to see all of you in Peru!

Despite all the "medical" use of ma*****na and it being prescribed for a wide range of conditions, there is little sound evidence that it is actually helpful for any mental health condition, as reviewed in this new publication:

"The current evidence base is not sufficient to support the use of cannabis for the treatment of mental health conditions and demonstrates substantial risks of adverse effects. Clinicians should engage patients with mental health conditions in discussions about cannabis use because use is common, has an influence on mental health symptoms, and is likely an important modifiable risk factor for mental health conditions in some populations."

In sad news, Dr. Judith Rapoport has passed away at age 93. She was an early giant in pediatric OCD research and lived an amazing life.

One of the highlights of my early career was being part of a panel on pediatric OCD at an international conference in Argentina, and noticing Dr. Rapoport was in the audience. She even commented us afterward on enjoying it. I was a bit star stuck!

Celebrate the life of Judith Rapoport, leave a kind word or memory and get funeral service information care of Hines-Rinaldi Funeral Home.

I'm excited to announce the imminent publication of "Advances in Mental Health Technology," a special bound issue of the journal Psychiatric Clinics of North America that I edited. In it you will find cutting edge articles on ethics, assessment, and treatment issues, such as digital phenotyping, wearable technology, virtual reality, chatbots and AI, and more!

A huge thanks to my contributors and co-authors from across the country!
