Company Overview

Personal Strengths Publishing is the company behind theSDI (Strength Deployment Inventory) and other assessments & services that help people improve their relationships and manage conflict more effectively.

The SDI was developed by psychologist, clinical therapist, educator, and author Elias H. Porter, Ph.D. It is the primary inventory of a suite of inventories based on his Relationship Awareness Theory - a group of ideas that help people to build productive relationships and manage conflict by providing a window into the motivation that drives behavior.

Dr. Porter's experience in clinical, industrial, military and governmental settings provided the rich diversity of environments needed to validate a comprehensive theory of relationships and the suite of inventories based on that theory. The awareness of self and others gained from the SDI helps people to improve all types of relationshipsÑbe they at home, work, school, social or otherwise.

He founded Personal Strengths Publishing, Inc. in 1971 and served as President of that company until his death in December, 1987. Today, there are Personal Strengths offices all over the world and the SDI is available in ten languages.
