Adult separation anxiety disorder is a recognized DSM-5-TR diagnosis — added in 2013 to acknowledge what clinicians had long observed: separation anxiety doesn’t always end in childhood. For many adults, it persists, develops in adulthood, or emerges after life transitions, causing significant distress and impairment.
According to research summarized by the National Institute of Mental Health, adult separation anxiety affects roughly 1-2% of adults — but is dramatically underdiagnosed because patients and clinicians often dismiss it as “just relationship insecurity” or “being too attached.”
What Adult Separation Anxiety Actually Is
DSM-5-TR criteria require developmentally inappropriate and excessive fear or anxiety concerning separation from attachment figures, evidenced by at least three of:
- Recurrent excessive distress when anticipating or experiencing separation
- Persistent worry about losing major attachment figures
- Persistent worry about events that could cause separation
- Reluctance to leave home, go to work, or be away from attachment figures
- Excessive fear of being alone
- Reluctance to sleep away from attachment figures
- Repeated nightmares involving separation
- Repeated physical symptoms when separation occurs or is anticipated
For adults, symptoms must persist 6+ months and cause significant impairment.
How It Presents in Adults
Adult separation anxiety can take many forms:
- Relationship anxiety — excessive worry about partner’s whereabouts, persistent need for contact, distress when apart
- Parental anxiety — difficulty when adult children move away, excessive worry about their safety
- Empty nest distress — going beyond normal adjustment to clinical level
- Anxiety about loved ones’ safety — persistent catastrophic thinking when family members are away
- Difficulty being alone — significant distress when not with attachment figures
- Travel anxiety — even short trips become distressing
When Does It Develop?
Adult separation anxiety can:
- Continue from childhood (about one-third of childhood cases persist)
- Develop in adulthood, often after life transitions
- Emerge after major losses or near-losses
- Worsen during pregnancy, postpartum, or major life changes
- Develop after illness in self or family
Why It’s Often Missed
- Diagnostic recognition is recent (2013)
- Symptoms often attributed to “relationship problems” or personality
- Patients themselves frequently embarrassed about adult-onset symptoms
- Overlap with generalized anxiety, agoraphobia, and panic disorder can mask the specific separation focus
- Cultural variation in attachment norms complicates assessment
Evidence-Based Treatment
SSRIs and SNRIs
First-line medications — same approach as other anxiety disorders. Address underlying anxiety biology over weeks of treatment.
CBT
Cognitive-behavioral therapy specifically focused on separation-related cognitions and gradual exposure to feared separations. Highly effective when systematically applied.
Couples or family therapy
When attachment anxiety significantly affects relationships, including the attachment figure in treatment often helps. Patterns of reassurance-seeking and accommodation can be addressed together.
Attachment-focused approaches
For patients whose adult separation anxiety has roots in early attachment patterns, attachment-focused therapy or schema therapy may be valuable.

Dismissal as “personality”
Adult separation anxiety often gets dismissed as relationship insecurity or being “too attached” — leaving patients without recognition that this is a treatable condition.
Specific recognition
Dr. Farkas recognizes adult separation anxiety, distinguishes it from related conditions, and provides evidence-based treatment.
Better attachment, less distress
Treatment doesn’t eliminate love or attachment — it reduces the painful intensity that interferes with functioning.
Common Questions About Adult Separation Anxiety
How do I know if I have this vs just being attached?
The line is functional impairment and distress level. Loving someone deeply isn’t a disorder. Being unable to function when they’re not present, persistently catastrophizing, or experiencing distress disproportionate to separation context is.
Does treatment make me care less about loved ones?
No — treatment reduces the painful, intrusive aspects of attachment anxiety. The love and connection remain; the suffering diminishes.
Is this just empty nest syndrome?
Empty nest can trigger or worsen adult separation anxiety, but they’re distinct. Normal empty nest adjustment resolves over months; clinical separation anxiety persists and impairs functioning. See our related article on adjustment disorders.
Will medication help?
SSRIs and SNRIs are first-line and often effective. Combined with CBT, most patients see substantial improvement.
