Feeling isolated indicates an inability to achieve which need, as outlined in suicide theories?

Feeling isolated is primarily linked to the need for belonging, which is a central concept in several psychological theories related to suicide. The need for belonging refers to the human emotional need to be an accepted member of a group, whether that is a family, friends, or a community. When individuals perceive themselves as isolated or disconnected from others, it can lead to significant emotional distress and contribute to feelings of hopelessness and despair, which are risk factors for suicidal thoughts and behaviors.

Belongingness is crucial to mental health; when this need is unmet, individuals may experience loneliness and worthlessness. Theories such as the Interpersonal Theory of Suicide underscore that thwarted belongingness is a key factor contributing to suicidal ideation and actions. In this context, when someone feels isolated, it reflects a struggle to fulfill this essential need for connection, which can ultimately lead to an increased risk of suicidal thoughts and actions.

Self-actualization, recognition, and empathy are important needs as well, but they do not directly capture the profound impact that isolation has on an individual’s mental state concerning suicidal risk. These other needs may influence a person's experience and perception of life but are not as closely tied to the fundamental emotional state induced by feelings of isolation.
