What Is Attachment Theory?

Attachment theory, developed by John Bowlby and Mary Ainsworth in the 1960s and 70s, describes how early relationships with caregivers create internal working models for how we approach closeness, trust, and intimacy throughout life.

Your attachment style isn't a life sentence. It's a starting point. Research consistently shows that attachment patterns can shift through awareness, healthy relationships, and therapeutic work. Understanding your style is the first step toward choosing how you relate rather than being driven by patterns you didn't choose.

Deep Personality measures attachment style using the ECR-S (Experiences in Close Relationships - Short Form), a validated instrument used in clinical research. Your attachment results are then integrated with your Big Five personality profile, emotional regulation patterns, and fifteen other measures to create a comprehensive picture of how you connect with others.
