IDI
Interpersonal Dependency Inventory (IDI)
The IDI is a self-report questionnaire designed to measure interpersonal dependency, that is, the tendency to markedly seek support, reassurance, and validation from others. It classically explores three dimensions: emotional reliance on another person, lack of social self-confidence, and assertion of autonomy. It helps identify a relational style characterized by a need for support, difficulty functioning alone, fear of separation, or low self-assurance in interactions.

Scoring & interpretation
Each item is rated on a Likert-type scale (usually from 1 to 5), reflecting how much the person agrees with each statement about their interpersonal relationships. Total scores are calculated by adding up the responses and are then broken down into the three subscales. A high score indicates greater interpersonal dependency.
