I was one of the authors and editors of A-Tjak & De Groot (Eds.) (2008). Acceptance and
Commitment Therapy; een praktische inleiding voor hulpverleners. Houten: Bohn Stafleu Van Loghum. I edited the second edition: A-Tjak (2015) Acceptance and Commitment Therapy. Theorie en praktijk.

I gave three workshops, one at the Worldcon in Enschede, one with Martin Brock in Parma and one with Kelly Koerner in Sydney. Additionally I presented the results of a meta-analysis done with Davis, Powers, Morina, Smits & Emmelkamp (2015) in Sydney at the worldconference and also at the EABCT conference in the Hague in 2014. This meta-analysis is published in Psychotherapy and Psychosomatics in 2015. In 2018 this article was published: A-Tjak, J., Morina, N., Topper, M., & Emmelkamp, P. (2018). A Randomized Controlled Trial in Routine Clinical Practice Comparing Acceptance and Commitment Therapy with Cognitive Behavioral Therapy for the Treatment of Major Depressive Disorder. Psychotherapy and Psychosomatics, 87(3), 154-163. DOI: 10.1159/000486807.
With Marco Kleen I presented a workshop RFT at the EABCT conference in the Hague.
I finished my PhD and defended my thesis succesfully at April 8th 2020: Unraveling the black dog. How can we improve treatment for depression and can Acceptance and Commitment Therapy contribute to the improvement? Together with Louise Hayes I wrote the chapter Depression in the Oxford Handbook of ACT (Editor M. Twohig et al, 2022).
