Self-disclosure and emotional intimacy:
How does self-disclosure foster emotional closeness in relationships?

Overview

Figure 1. Stock image of couple hugging Picture this... Jim and Pam have been dating for a few months; things have been going well but at times there is noticeable emotional distance between them. One night Jim tells Pam that “I haven’t talked to anyone about this, but I’m terrified one day you will get bored and leave”, this confession opens the flood gates for Jim and Pam to share their deepest fears and anxieties. In this moment, an invisible barrier dissolves, they have discovered a new profound sense of trust and understanding. A new and deeper layer of their relationship has been unlocked; there is an emotional closeness that wasn’t there before. Why does this self-disclosure from Jim create this emotional closeness between him and Pam?

• Depth levels: Superficial layer (publicly observable characteristics), Intimate layer (opinions, worldviews ect.), Personal layer (fears, goals, secrets), Core layer (highly protected, emotional needs & vulnerabilities). (See figure 2).

The 5 stages of social penetration: Orientation, Exploratory affective exchange, Affective exchange, Stable exchange, Depenetration (see below, Table 1).

Table 1. The 5 stages of social penetration & examples.

Five stages of social penetration	Examples
Orientation	Small talk, adhering to social norms
Exploratory affective exchange	Personal attitudes & preferences
Affective exchange	Casual relaxed communication, honest opinions, deeper emotional disclosures
Stable exchange	Open connection, deep core values, emotional reactions are predictable
Depenetration	Optional phase, communication breadth & depth withdraw

Social exchange theory (Thibaut & Kelley, 1959)

• Rewards (benefits) vs costs of self-disclosure (cost-benefit analysis)
• Eg. Rewards: companionship, validation, emotional relief. Costs: fear of rejection, loss of privacy, judgement.
• Relationships thrive when self-disclosure remains profitable.
