Taking its place alongside relationship classics The 7 Habits of Highly Effective People and How to Win Friends and Influence People, Dr. Jan Yager’s When Friendship Hurts, in print since being published twenty-two years ago, is now available in a second edition containing new original research.

Friendship expert, coach, and sociologist Dr. Jan Yager’s prescriptive book on toxic friendships, what to do about them, and how to find or improve the positive friendships we all deserve, also has an updated Preface, bibliography, and resources section.

The Preface shares Dr. Yager’s more recent research that asks the question, “Have you ever had a friendship that made you physically or emotionally sick?” She was surprised to find that such strong reactions were more common than she originally thought. Forty-three percent of the ninety men and women she surveyed answered “Yes” to that question. In the new Preface, she shares their most common reactions.

Another new feature of Dr. Yager’s classic book includes cartoons at the beginning of each chapter by artist Cathy Wilcox and originally done for the Australia/New Zealand edition.

When Friendship Hurts has helped countless men and women to better understand why they get involved in a toxic friendship, and then explore possible ways to mend it, let it fade, or end it.
