In her book "Our Inner Conflicts" published in 1945, Karen Horney describes types of people based upon their interpersonal coping strategies.

• The Compliant Type - those who move toward people
• The Aggressive Type - those who move against people
• The Detached Type - those who move away from people

The following Enneagram types are the best fit for these interpersonal strategies as described by Karen Horney.

• Enneagram Type 2 - moving toward people
• Enneagram Type 8 - moving against people
• Enneagram Type 5 - moving away from people

However, the Enneagram authors have generalized her types into 3 triads on the Enneagram - in the process, renaming the detached type to the withdrawn type.

• Enneagram Types 1, 2 and 6 - Compliant Types
• Enneagram Types 7, 8 and 3 - Aggressive Types
• Enneagram Types 4, 5 and 9 - Withdrawn Types

An earlier variation that may still be found in some Enneagram teachings swaps types 1 and 7 so that type 7 is a compliant type and type 1 is an aggressive type.
