Social Justice in Clinical Practice:  Boston Liberation Health Theory and Methods

Boston Liberation Health

Clinicians are on the frontlines of our current political crisis. We witness, on a daily basis, the economic, racial, and cultural oppression our clients are experiencing, which can be a form of trauma in itself. Yet providers are often at a loss as to how to explore and discuss the effects of sociopolitical problems with the individuals and families they work with. This workshop will introduce practitioners to the liberation health framework; a social justice focused model of clinical practice which integrates analysis of cultural, social, and political forces with traditional clinical methods. Participants will learn about how sociopolitical factors and systemic forces influence individual traumas and explore ways to shift the personal narratives clients bring to the therapy space. Following an overview of liberation health theory, participants will practice applying this model to their clinical practice.

Transforming Silence: Antiracism and Authentic Connection as Mental Health Colleagues.

by Brandon Jones, PhD

As a community committed to understanding and responding to the effects of severe and prolonged trauma, NESTTD has collective expertise on how guilt, shame, and negation prevent people from enjoying the fullness of posttraumatic healing. What if we turn our gaze inward? The racist and sexist forces that construct our society - perpetuated by the violence of silence -also shape the physical and relational spaces shared by counseling professionals.

How do racial guilt, racial shame, and racial negation aggravate wounds caused by racism and prevent well-meaning colleagues from authentically connecting? In this training, you are invited to critically examine how your racial emotions and self-conscious affect your antiracist commitment through didactic instruction, prompted self-reflection, small group break-outs, and large group discussion.

    Fundamentals 2021 Morning Plenary

    by Sandy Dixon, PsyD

    Many trauma experts formulate their therapeutic approaches to clients on the basis of their conceptualization of "complex traumatic stress disorders." Yet what are these? The renowned researcher and clinician, Bessel van der Kolk says, "Dissociation is the essence of trauma," and yet few graduate schools teach anything about dissociation. Our most challenging clients struggle with the long-term effects of insecure or disorganized attachment compounded by the impact of multiple instances of overt trauma.  This program is designed for graduate students, behavioral health and social service providers, and psychotherapy providers who are new to learning about and working with the complex trauma spectrum. Topics introduced in the morning plenary session will include the concept of developmental trauma, attachment research, basics of relevant neurobiological research, core challenges of trauma survivors, assessment of dissociation and dissociative disorders, differential diagnoses, barriers to collaborative therapeutic relationships, and goals of therapy.
