In this webinar, participants will learn about key psychological flexibility processes that can be engaged to promote resilience in service members. Participants will be introduced to the psychological flexibility model (Hayes et al., 2006) and the flexibility sequence (Bonanno, 2021). The convergence of the fields of contextual behavioral science and stress/trauma on core processes of resilience will be highlighted. An in-development program for training these processes will be described (Evans et al., in press). New knowledge gained from this webinar will support conceptualization, prevention, and intervention. The skills introduced will be relevant to both treatment and training contexts.
