Two books people buy for the same problem, built on completely different foundations.
Verdict
Attached has the stronger evidence behind it; Codependent No More has the sharper description of the behaviour. Attached translates adult attachment research into anxious, avoidant and secure styles, and that research literature is real and substantial. Codependent No More comes out of the recovery movement, where codependency is a popular concept rather than a clinical category, and it is very good at describing the compulsive caretaking it names. If you want to know why you do it, read Attached. If you want to see yourself on the page, read Beattie.
| Codependent No More | Attached | |
|---|---|---|
| Foundation | The recovery movement | Adult attachment research |
| Central concept | Codependency | Anxious, avoidant and secure styles |
| Clinical standing of the concept | Not a recognised diagnosis | Attachment style is a studied construct |
| Focus | Your own behaviour | The interaction between two people |
| Practical guidance | Extensive | Moderate |
| Tone | Recovery and self-honesty | Explanatory and reassuring |
You keep managing other people's feelings at your own expense and you want that pattern named without euphemism. Beattie is unsparing about the payoff in caretaking, which is the part most readers had not looked at, and the book is full of the small specific behaviours that make the pattern recognisable rather than abstract.

You want to understand the dynamic rather than only your half of it. The anxious and avoidant pairing that Attached describes explains a great deal of why the same argument keeps happening, and it does so without making either person the villain. The research framing also makes it an easier book to hand to a partner.
No. It is not in the DSM or the ICD, and there is no agreed definition or measure of it. That does not make the described behaviour imaginary. It does mean you should treat codependency as a useful popular label for a cluster of habits rather than as a condition you have been diagnosed with.
Attachment in infancy is one of the better-replicated areas of developmental psychology. The extension to adult romantic styles is well studied but softer, and the neat three or four category model in popular books is a simplification of something more continuous. Useful, and not as tidy as the quiz makes it look.
Both books are pointing at behaviour you did not choose consciously and would rather not look at, which is the same territory shadow work covers. The books give you a framework. Sitting with what the framework reveals about you is the practice.

Our Codependent No More review covers the pattern the book describes well, and why codependency is a popular label rather than a clinical diagnosis.
