The approach that represents a model of self-disclosure that reflects both breadth and depth of shared information is __________.

A) the Johari window
B) social exchange theory
C) the relational dialectics approach
D) the social penetration model

The social penetration model, developed by Altman and Taylor, proposes that self-disclosure increases in both breadth and depth as relational intimacy grows. Individuals gradually reveal more intimate and personal information about themselves, as well as information about a wide range of topics. As a result, the social penetration model provides a comprehensive model for understanding the process of self-disclosure.
