What is the sense of belongingness theory?
The sense of belongingness theory, also known as the need to belong theory, is a fundamental concept in social psychology that explains the human drive for social connection and acceptance. This theory, proposed by Roy Baumeister and Mark Leary in 1995, posits that humans have an innate and pervasive motivation to form and maintain at least a minimum number of positive, significant interpersonal relationships.
At its core, the theory suggests that the need to belong is a fundamental human motivation, as essential to our well-being as food and shelter. This need is characterized by two main features:
- People require frequent, positive interactions with others.
- These interactions must occur within a framework of long-term, stable care and concern.
The sense of belongingness theory has important implications for understanding human behavior, emotions, and mental health. When individuals feel a strong sense of belonging, they tend to experience positive emotions and better overall well-being. This belongingness is also linked to prosocial relating behaviour.
Conversely, when this need is not met, it can lead to feelings of loneliness, social isolation, anxiety, depression, and other negative psychological outcomes.
