If Jessica Fern’s Polysecure is the heavyweight textbook of attachment in ENM, Lauren Nash’s Attachment Theory Workbook for Polyamory is the more approachable, hands-on cousin. Published in 2022, it takes the sometimes abstract concepts of attachment theory and translates them into bite-sized exercises aimed at helping poly folks actually apply the ideas in their relationships.

What It’s About

The book starts with a crash course in attachment theory — secure, anxious, avoidant, disorganised — then pivots quickly into practical tools. Unlike Polysecure, which builds a big theoretical frame, Nash dives straight into worksheets and strategies for identifying patterns, soothing insecurity, and creating stronger connections.

Core elements include:

• Self-assessment quizzes. To help readers identify their attachment style(s).
• Scenario-based exercises. What do you do if your partner cancels a date for someone else? How do you soothe yourself when a metamour is introduced?
• Partner activities. Prompts for honest conversations around boundaries, reassurance, and shared needs.
• Poly-specific reframing. For example: distinguishing between jealousy rooted in attachment insecurity vs jealousy as a legitimate signal of unmet needs.

Strengths

• Accessible. Written in plain language, it’s easy to pick up and use without needing a psych background.
• Poly-specific. Where mainstream attachment books assume monogamy, Nash zeroes in on non-monogamous situations.
• Action-oriented. Like Labriola’s workbooks, it’s not just theory — it’s stuff you can literally try tonight.

Weaknesses

• Surface-level theory. If you’ve already read Polysecure, much of the intro may feel like review.
• Simplistic at times. Some exercises land closer to pop psychology than clinical depth. Serious trauma or deeply ingrained patterns may need more than what’s offered here.
• Repetition. Some readers report the exercises feel similar or redundant after a while.

Why It Still Matters

Not everyone wants to wrestle with Fern’s dense, therapy-driven framework. Nash offers a gentler on-ramp: if you’re anxious about a partner’s date or avoidant when things get intense, this book gives you immediate, tangible things to do. It’s not a full theory of polyamory, but it’s a helpful toolkit for individuals and couples wanting to stabilise their attachment habits.

In that sense, it’s less the “groundbreaking revelation” and more the “steady workbook” — a companion piece that makes attachment concepts usable for everyday poly life.
