Analysis

The Self-Disclosure Index is used to evaluate the degree and type of information that an individual chooses to disclose about themselves to others.

Purpose

The main purpose of the Self-Disclosure Index is to measure how open or closed a person is in relation to sharing personal information with others, to analyze the various categories of self-disclosure such as emotional, personal, and social, and to examine the effects of self-disclosure on an individual’s relationships, sense of intimacy, and social support.

Calibration

The index usually includes questions or statements related to the frequency, quality, and type of self-disclosure. Participants rate these statements on a Likert scale or another type of scale.
