WHAT THE TEST MEASURES

About This Assessment

Life Style Index (LSI) Test - Symptoms and Signs

defense mechanisms

In clinical and counseling contexts, the Life Style Index (LSI) is used to characterize an individual’s typical patterns of psychological defense in response to stress and internal conflict. It is a self-report inventory intended to support case conceptualization by describing relative reliance on common defensive styles.

The measure contains 97 items and typically requires about 18 minutes to complete. Results are generally interpreted as a profile of defense-related tendencies and their relative prominence, which may inform treatment planning, psychoeducation, and tracking change over time when used alongside other clinical data. The Life Style Index (LSI) is not a stand-alone diagnostic instrument and should be integrated with interview findings and relevant collateral information.
