Interpersonal Dependency Inventory (IDI) Test - Description and methodology of the test
People who want to understand how independence, approval, closeness, and support shape their relationships may find the Interpersonal Dependency Inventory (IDI) Test useful for structured self-reflection. This interpersonal dependency assessment is intended for people who can consider their usual reactions and decisions. The result offers a profile of tendencies rather than a single label, helping you notice where reliance and self-direction coexist.
What This Assessment Explores
Taken as a dependency inventory, the questionnaire separates self-sufficiency, uncertainty, support seeking, and broader reliance rather than treating closeness as dependency alone. Its items address help, disagreement, approval, decisions, reassurance, and fears of losing important relationships. The profile may reveal mixed patterns, such as high independence alongside strong sensitivity to others’ opinions.
The four displayed scales are:
- Need for Autonomy (14-56) measures self-sufficiency and distance from others: Lower autonomy (14-22), Moderate autonomy (23-34), Higher autonomy (35-56).
- Self-Doubt (16-64) measures uncertain judgment and difficulty deciding alone: Low (16-24), Moderate (25-38), High (39-64).
- Emotional Reliance on Others (18-72) measures needs for care, advice, and external evaluation: Low need for support (18-37), Moderate need for support (38-55), High need for support (56-72).
- Dependency (-22-122) measures overall emotional and behavioral reliance: Low dependency (-22-34), Moderate dependency (35-63), High dependency (64-122).
Methodology and Scientific Basis
An interpersonal dependency questionnaire like this uses self-report rather than observed behavior. The representative items use four response points, usually running from Not characteristic of me to Very characteristic of me, with some wording shifting to Not true of me or stronger intensity labels. You judge how well each statement fits, so answers are sensitive to current context and self-awareness.
Responses are combined into numerical totals with descriptive bands. The displayed bands are the catalogue’s descriptive interpretation; the cited evidence concerns the original instrument rather than this online presentation.
This questionnaire is an online administration of the original 48-item Interpersonal Dependency Inventory (IDI), using its four-scale structure. Bornstein’s 1994 construct-validity review and 1997 retest study provide evidence about the original inventory’s construct and score stability, not identical validity for this digital presentation.
Socially desirable responding may soften or exaggerate a pattern. Read the profile as a prompt to examine recurring ways of seeking support, making decisions, and responding to closeness within the wider context of your experiences.
