In psychology, emotional detachment, also known as emotional blunting, is a condition or state in which a person lacks emotional connectivity to others, whether due to an unwanted circumstance or as a positive means to cope with anxiety. Such a coping strategy, also known as emotion-focused coping, is used when avoiding certain situations that might trigger anxiety. It refers to the evasion of emotional connections. Emotional detachment may be a temporary reaction to a stressful situation, or a chronic condition such as depersonalization-derealization disorder. It may also be caused by certain antidepressants. Emotional blunting, also known as reduced affect display, is one of the negative symptoms of schizophrenia.

Emotional detachment may not be as outwardly obvious as other psychiatric symptoms. Patients diagnosed with emotional detachment have reduced ability to express emotion, to empathize with others or to form powerful emotional connections. Patients are also at an increased risk for many anxiety and stress disorders. This can lead to difficulties in creating and maintaining personal relationships. The person may move elsewhere in their mind and appear preoccupied or "not entirely present", or they may seem fully present but exhibit purely intellectual behavior when emotional behavior would be appropriate. They may have a hard time being a loving family member, or they may avoid activities, places, and people associated with past traumas. Their dissociation can lead to lack of attention and, hence, to memory problems and in extreme cases, amnesia. In some cases, they present an extreme difficulty in giving or receiving empathy which can be related to the spectrum of narcissistic personality disorder. Additionally, emotional blunting is negatively correlated with remission quality. The negative symptoms are far less likely to disappear when a patient is experiencing emotional blunting.

In a study of children ages 4–12, traits of aggression and antisocial behaviors were found to be correlated with emotional detachment. Researchers determined that these could be early signs of emotional detachment, suggesting parents and clinicians to evaluate children with these traits for a higher behavioral problem in order to avoid bigger problems (such as emotional detachment) in the future.

A correlation was found of higher emotional blunting among patients treated with depression who scored higher on the Hospital Anxiety and Depression Scale (HADS) and were male (though the frequency difference was slight).

Emotional detachment in small amounts is normal. For example, being able to emotionally and psychologically detach from work when one is not in the workplace is a normal behavior. Emotional detachment becomes an issue when it impairs a person's ability to function on a day-to-day level.

While some depression severity scales provide insight to emotional blunting levels, many symptoms are not adequately covered. An attempt to resolve this issue is the Oxford Depression Questionnaire (ODQ), a scale specifically designed for full assessment of emotional blunting symptoms. The ODQ is designed specifically for patients with Major Depressive Disorder (MDD) in order to assess individual levels of emotional blunting.

Another scale, known as the Oxford Questionnaire on the Emotional Side-Effects of Antidepressants (OQESA), was developed using qualitative methods.

Emotional detachment and/or emotional blunting have multiple causes, as the cause can vary from person to person. Emotional detachment or emotional blunting often arises due to adverse childhood experiences, for example physical, sexual or emotional abuse. Emotional detachment is a maladaptive coping mechanism for trauma, especially in young children who have not developed coping mechanisms. Emotional detachments can also be due to psychological trauma in adulthood, like abuse, or traumatic experiences like war, automobile accidents etc.
