CLEAR ANSWERS TO COMMON QUESTIONS

Frequently Asked Questions

What does this questionnaire measure?

Who should complete the questionnaire?

It should be completed by an adult who has consistent, direct observations of the teenager across settings. Self-report is not recommended.

What observation period is required before rating items?

Ratings should be based on repeated observations over time, not on a single incident. If an item cannot be observed, select the option that indicates insufficient information.

How long does it take, and how many items are included?

Completion time is approximately 10 minutes. The questionnaire includes 53 items.

How should results be used?

Results support screening and intervention planning by identifying patterns of immature behavior. They should be interpreted alongside other information and not used as the sole basis for high-stakes decisions.

WHAT THE TEST MEASURES

About This Assessment

Detailed Infantility Test (DIT) - Symptoms and Signs

infantilism

This observer-rated questionnaire is designed to screen for developmentally immature (infantile) behavior patterns in adolescents across everyday contexts. The Detailed Infantility Test (DIT) is intended for completion by an adult who knows the youth well (e.g., teacher or other consistent observer) and can rate behavior based on repeated, real-world observation.

The measure contains 53 items and typically takes about 10 minutes to complete. Scores from the Detailed Infantility Test (DIT) may be used to support clinical formulation and to identify domains where immature behavior is more prominent, informing monitoring and intervention planning; it should be interpreted within the broader assessment context.
