Core Methodologies & Modalities
Trauma-Informed Stabilization Treatment (TIST)
Definition: TIST is a parts-informed, phase-oriented treatment model developed by Janina Fisher, PhD. It prioritizes nervous system regulation and safety over memory processing, reframing “unsafe” behaviors (like self-harm) as adaptive survival strategies driven by fragmented parts.
Master This Model: TIST Training: Healing the Fragmented Selves
Internal Family Systems (IFS)
Definition: Internal Family Systems is an evidence-based psychotherapy that conceptualizes the mind as a system of sub-personalities or “parts” referred to by IFS expert Frank Anderson, MD a Managers, Firefighters, and Exiles, led by a core, undamaged “Self.” It is foundational for treating complex trauma without pathologizing the client.
Acquire New Depth of Skill: IFS-Inspired Trauma Healing with Frank Anderson, MD
Polyvagal Theory
Definition: Developed by Dr. Stephen Porges, Polyvagal Theory describes how the autonomic nervous system searches for safety (neuroception) and organizes physiological states (Ventral Vagal, Sympathetic, Dorsal Vagal). It explains the physiological basis of “shut down” versus social engagement.
Master This Model: Treating Trauma and Addiction with the Felt Sense Polyvagal Model with Jan Winhall, MSW, PIFOT
Somatic Therapy
Definition: Somatic Therapy is a body-centered approach that accesses trauma stored in the body’s tissues and nervous system. It uses interventions like tracking sensations, movement, and breath to complete defensive responses that were thwarted during the original trauma.

Memory Reconsolidation
Definition: Memory Reconsolidation is the brain’s innate neurobiological mechanism for unlocking, updating, and re-saving a specific emotional memory. Unlike symptom management, it can permanently remove the traumatic charge of a memory while keeping the autobiographical facts intact.

The Theradelic Approach
Definition: An integrated framework developed by Sunny Strasburg that combines Internal Family Systems (IFS), archetypal psychology, and psychedelic-assisted therapy to facilitate deep healing and transformation.
Master Psychedelic Therapy with The Theradelic Approach Certification
Psychodrama
Definition: An experiential form of therapy where clients use spontaneous dramatization, role-playing, and dramatic self-presentation to investigate and gain insight into their lives.
Become the Expert: Transforming Relational Trauma with Psychodrama with Tian Dayton, Phd
Sensorimotor Psychotherapy
Definition: A body-centered talk therapy integrating cognitive and emotional processing with somatic interventions. It targets the physical symptoms of trauma by helping clients safely process uncompleted survival responses that remain trapped in the nervous system, facilitating bottom-up physiological regulation.
Integrate Somatic Stabilization: Healing the Fragmented Selves with Janina Fisher
Cognitive Behavioral Therapy (CBT)
Definition: Focuses on identifying and changing negative thought patterns and behaviors, making it highly effective for anxiety and depression.

Dialectical Behavior Therapy (DBT)
Definition: A subset of CBT that helps with emotional regulation, distress tolerance, and interpersonal skills, often used for borderline personality disorder.

Clinical Conditions & Presentations
Complex PTSD (C-PTSD)
Definition: A condition resulting from prolonged, repeated trauma (often relational), characterized by emotional dysregulation, negative self-concept, and interpersonal difficulties, including addiction, in addition to standard PTSD symptoms.

Attachment Disorder
Definition: A disruption in the formation of a secure emotional bond with a primary caregiver, often leading to difficulties in forming healthy relationships and regulating emotions in adulthood.
Free Training: Treating Attachment Disorder with Deirdre Fay, MSW
Gender Dysphoria
Definition: The psychological distress that results from an incongruence between one’s sex assigned at birth and one’s gender identity. Modern therapy affirms gender diversity rather than treating it as a pathology.
Build Your Skill: Non-Binary Psychology Training for Therapist Sarah Burgamy, PsyD
Dissociation
Definition: A disconnection between a person’s thoughts, memories, feelings, actions, or sense of who they are. In trauma therapy, it is viewed not as a deficit, but as a creative survival strategy to distance oneself from overwhelming pain.
Deep Dive: Understanding Dissociation with Jamie Marich, PhD
Disordered Eating (Attachment Lens)
Definition: Viewing disordered eating behaviors not merely as issues with food, but as attempts to manage attachment wounds and emotional dysregulation.
Free Training: Attachment, Food, and Diet Culture with Vanessa Scaringi and Kathryn Garlande
Essential Clinical Concepts
Neuroception
Definition: Neuroception is the sub-cortical process by which the nervous system constantly evaluates the environment for signs of safety, danger, or life threat. This occurs below the level of conscious awareness.
Free Training: Neuroception and Polyvagal for Therapists with Jan Winhall, MSW, PIFOT
Structural Dissociation
Definition: The theory that trauma causes the personality to divide into an “Apparently Normal Personality” (ANP) that handles daily life, and one or more “Emotional Personalities” (EP) that hold traumatic memories.
Free Training: Healing the Fragmented Selves Webinar with Janina Fisher, PhD
Window of Tolerance
Definition: The optimal zone of arousal where a person can function and process emotions effectively. Trauma therapy aims to widen this window so clients can handle stressors without swinging into hyperarousal or hypoarousal.

Therapeutic Presence
Definition: The clinician’s ability to be fully attuned, grounded, and emotionally available in the moment. Research indicates that the quality of presence is a stronger predictor of therapeutic outcome than the specific modality used.
Become a Master Therapist: The Deliberate Practice Approach to Clinical Greatness with Tori Olds, PhD
Ancestral/Intergenerational Trauma
Definition: The transmission of traumatic effects from one generation to the next, occurring through learned behaviors, attachment patterns, and epigenetic changes to gene expression.
Related Course: Breaking the Cycle of Intergenerational Trauma with Dafna Lender, LCSW
Cultural Humility
Definition: A lifelong commitment to self-evaluation and addressing power imbalances in the patient-provider dynamic. It requires the therapist to step back from being the “expert” on the client’s cultural experience.
Free Training: Liberatory Connections: Healing the Impact of Systemic Trauma with Akilah Riley-Richardson, MSW, CCTP
Self-Energy
Definition: In IFS, Self-Energy is the state of calm, curiosity, compassion, and confidence that exists within everyone. It is the healing agent of the internal system, unburdened by trauma, and is highly intuitive.
Study with the Expert: Working with Self-Energy and Intuition with Frank Anderson, MD
Epigenetics
Definition: The study of how behaviors, environment, and internal regulation can cause changes that affect the way genes work. It provides the biological framework for understanding how trauma can be passed down intergenerationally.
Study with the Expert: Nervous System Regulation Therapy with Linda Thai, LMSW
Vicarious Trauma
Definition: The cumulative transformative effect on the helper of working with survivors of traumatic life events. It involves a shift in the therapist’s world view and nervous system regulation.
Free Training: Preventing Therapy Burnout and Secondary Trauma with Arielle Schwartz, PhD
Moral Injury
Definition: The distressing psychological aftermath of exposure to events that contradict one’s deeply held moral beliefs. It is distinct from PTSD and focuses on the dimension of conscience.
Join the Trauma-Informed Therapy Community: The Trauma Wisdom Circle
Neuroplasticity
Definition: The brain’s ability to reorganize itself by forming new neural connections throughout life. This mechanism allows therapy to rewire deep-seated trauma patterns.
