McHugh/Stewart’s first big book on selfing processes. This is an edited volume, so it doesn’t hang together quite as nicely as their newer “A Contextual Behavioral Guide to the Self,” but it’s still useful and contains some nice work. I especially appreciated Kelly Wilson’s chapter on the ways mindfulness can help develop healthy self processes.

Most would agree self-as-context is the most challenging of the core ACT processes. If you want a deep dive into the process, I don’t think there’s a better volume out there. This is essential reading for anyone wanting to understand selfing repertoires, the types of problems that can occur when we engage in selfing behavior, and the ways in which the language we use can influence “who we are.”
