Attachment Psychotherapeutic Counselling Diploma 

Level 5 Awarded and Accredited by CPCAB

Why attachment-informed therapy matters

More clients are arriving in therapy with language for trauma, attachment, nervous system responses and relational patterns. They may have read the books, listened to the podcasts, completed previous therapy or learnt coping strategies – and still feel stuck.

For practitioners, this can create a familiar clinical tension: the client understands the problem, but something deeper is still repeating.

Attachment-informed therapy helps you make sense of the protective strategies, emotional responses and relational patterns that sit beneath the presenting issue.

This diploma gives you a practical, clinically grounded way to bring attachment theory into formulation, regulation, rupture and repair, and the therapeutic relationship itself.

Who is this course for?

You may have only touched briefly on attachment theory in your initial training, but you will have met it in the therapy room: in shame, avoidance, mistrust, dysregulation and painful relational patterns.
This Level 5 Diploma equips qualified counsellors and psychotherapists to understand what is happening beneath these moments and work with them more confidently, using attachment theory as a practical, clinically alive map for what happens in the therapeutic relationship.

How Optima supports you on your Level 5 Journey

We know this training asks something of you, personally and professionally, so support is built into the course from the beginning.
You will be supported through:
  • A clear Level 7 learning pathway so you understand how the course develops and how each stage builds your clinical confidence, theoretical depth and professional identity.
  • Tutor guidance at key milestones to help you stay on track with your learning, written work, clinical thinking and research development.
  • Advanced teaching that links theory to real therapeutic practice, so attachment, trauma, relational process, rupture and repair, supervision and research all stay connected to the therapy room.
  • Support with research and critical thinking, helping you develop your ideas, engage with literature and connect research to meaningful clinical questions.
  • Case discussion and practice-based reflection, so you can explore how attachment-focused practice shows up in real client work, supervision, couples work or professional development.
  • A safe relational learning environment, where depth, uncertainty, challenge and vulnerability can be explored without you feeling exposed or left on your own.
  • Reflective work on yourself as therapist, including your own attachment responses, defences, relational patterns, countertransference and use of self in the therapeutic relationship.
  • Supportive challenge, because Level 7 learning should stretch you, but it should not leave you feeling unsupported.
  • Peer connection and cohort learning, giving you a thoughtful professional community where ideas, clinical questions and personal reflections can be shared.
  • Clear structure around assignments and expectations, so the academic level feels manageable, purposeful and connected to practice.
  • Space to develop your attachment-informed specialism, whether your focus is supervision, couples therapy, research, advanced clinical practice or senior professional development.
  • Encouragement beyond the course, including pathways into supervision, couples work, research-informed etc

Diversity and Inclusion

Throughout the Level 5 diploma, diversity, identity, and inclusive practice are thoughtfully woven into teaching, case material, skills development, and reflective learning. The programme is culturally attuned, neurodiversity-informed, and aligned with the BACP Ethical Framework, creating learning spaces that are respectful, curious, and ethically grounded. Attention is given to difference, culture, power, and social context as essential parts of counselling practice, rather than something added on or treated separately.

As a student, you will be gently supported to explore your developing professional identity alongside your own values, assumptions, and lived experience. Through reflection, discussion, and relational learning, you will begin to notice how issues of power, difference, and positionality can show up in counselling relationships and in your work with clients. The course encourages thoughtful, compassionate engagement with complexity and difference, helping you to grow in confidence as an ethical, inclusive practitioner who can work with care, sensitivity, and respect within your scope of practice.
