Multidimensional Partner Trauma Model
What is the Multidimensional Partner Trauma Model?
Navigating betrayal trauma requires a therapeutic approach that acknowledges its layered and multifaceted impact. At The Therapy Collective, we draw on the Multidimensional Partner Trauma Model (MPTM) developed by APSATS, allowing us to address the many dimensions of trauma experienced by individuals, couples, and families.
Historically, partners or families of a person struggling with compulsive sexual behaviours and/or substance abuse were seen as “codependents” or “co-addicts”. Co-dependency involves an excessive emotional or psychological dependence on others, often driven by a strong need to feel needed, even when it compromises one’s own well-being. At The Therapy Collective, we recognise that while co-dependency can appear in relationships impacted by betrayal trauma, it is essential to first address the traumatic impact, emotional and psychological effects of broken trust within a close relationship before working on any underlying codependent patterns.
How does the MPTM work?
In healing from betrayal trauma, the Multidimensional Partner Trauma Model offers a structured framework that supports individuals, couples, and families through three key stages. Each stage targets a different aspect of the trauma, helping you establish safety, work through the pain, and ultimately rebuild connection with yourself and those close to you.
The first phase is focused on safety and stabilisation. After discovery or confession of betrayal, our sense of security can be shattered leaving us feeling vulnerable and uncertain. Therapy focuses on helping you process and manage the many complex and confusing emotions and triggers. Depending on your circumstances, preparing you for a formal disclosure may also be part of this early work. The APSATS model recognises that partners cannot achieve safety unless they have access to the truth and information that they need to move forward.
In the second stage, partners begin the work of remembering and grieving the pain caused by betrayal. This can be an emotionally charged phase as you confront and process the meaning of your experience and feelings that may have been long suppressed. As you move further along in your healing, the third stage shifts toward reconnecting with yourself and rebuilding healthy relationships: restoring trust, creating a vision for the future, and exploring any past trauma or family-of-origin patterns that may influence your experiences.
The APSATS model also focuses on a compassionate approach to supporting the person with compulsive sexual behaviour as well helping them to improve their sense of self along with teaching them the skills of empathy, validation, and reassurance for the partner.
Our Approach at The Therapy Collective
Whilst the three stages of the Multidimensional Partner Trauma Model is a helpful roadmap to make sense of the recovery process, we recognize that each client’s journey is unique and individualised. The impacts of infidelity are not static or linear, hence we prioritise and honour recovery at your pace – walking alongside you every step of the way, providing the guidance, support, and understanding for your particular needs and challenges.
Our trained, compassionate partner specialist will work with you to establish a safe therapeutic environment where you can express emotions and concerns without judgment. Initially our work will likely explore coping strategies, identify support systems, and develop a personalised safety plan to guide you through the process of regaining stability. Together with other trauma informed and integrative approaches, we will navigate the shock, sense of abandonment, grief and anger that can often accompany betrayal trauma. As you move towards recovery and growth, we will focus on empowerment through a rediscovery of self- worth, strength and resilience enabling healthier connections with yourself and others.
In our couple and family work, focus is on repairing the relationship through honesty and transparency, effective communication skills, rebuilding safety, trust and establishing relational patterns for healthier connection.
At The Therapy Collective, we understand the profound impact of betrayal trauma and the importance of finding the right therapist to guide you through your journey. Our expertise in supporting individuals, couples, and families affected by betrayal trauma, infidelity, and compulsive sexual behaviour ensures that you receive the appropriate support and guidance. Together we help you recover and thrive.
