WHAT THE TEST MEASURES
About This Assessment

Inventory of the Dimensions of Emerging Adulthood (IDEA) Test - Symptoms and Signs

This self-report measure assesses subjective experiences associated with the transition from adolescence to adulthood. The Inventory of the Dimensions of Emerging Adulthood (IDEA) is intended to capture perceived developmental themes commonly reported in emerging adulthood.

The questionnaire contains 19 items and typically takes about 4 minutes to complete. It was developed by Jeffrey Jensen Arnett and is generally used in clinical, counseling, and research contexts to support a structured discussion of how an individual views their current life stage.

Scores from the Inventory of the Dimensions of Emerging Adulthood (IDEA) can help characterize areas such as exploration, perceived instability, self-focus, and feelings of being in-between. Results should be interpreted in context and used alongside clinical interview data and other relevant measures.
