The Life Styles Inventory (LSI) and Self Development Guide (LSI 1):

The Life Styles Inventory (LSI) measures 12 specific styles or patterns of thinking that can either help or hinder a person from reaching his or her potential. Research has shown that the styles measured by the LSI are related to a number of indicators of effectiveness and success, including leadership effectiveness, management effectiveness, problem solving effectiveness, quality of interpersonal relations, salary, organizational level, individual health and well being, and organizational culture. The 12 styles measured by the LSI are organized into three general clusters:

• Constructive
• Passive/Defensive
• Aggressive/Defensive
