Which influential psychology book was written by Thomas Anthony Harris in 1969?

The book "I'm OK, You're OK," authored by Thomas Anthony Harris in 1969, is a significant work in the field of transactional analysis, a branch of psychology that explores social interactions and communication. In this book, Harris outlines the framework of transactional analysis, which breaks down human interactions into three ego states: Parent, Adult, and Child. This concept helps individuals understand their own behaviors and those of others, promoting better communication and relational dynamics.

The title itself reflects a positive outlook on interpersonal relationships, suggesting that individuals can maintain a healthy self-esteem and foster mutually respectful relationships. Harris's book not only contributed to the field of psychology but also appealed to a broad audience, aiding people in personal growth and enhancing their social skills. The insights provided in "I'm OK, You're OK" continue to influence therapeutic practices and self-help methodologies today.

Other choices, while notable in their own rights, do not relate specifically to Harris's work. Each covers different themes, such as self-improvement or the psychology of relationships, but none encapsulate the core principles of transactional analysis that Harris presented.
