Separation Anxiety Disorder

DSM-5 criteria - developmentally inappropriate fear of separation from attachment figures.

1 What is the Separation Anxiety Disorder?

The Separation Anxiety Disorder is a psychosocial scoring tool used in paediatric practice. DSM-5 criteria - developmentally inappropriate fear of separation from attachment figures. It scores 8 criteria and interprets the total across 2 bands, so the number always arrives with the severity it implies rather than on its own. In PediAid each criterion is shown as a labelled option with the weight it carries, so the total can be checked rather than taken on trust.

2 When to use it

  • Grading severity at the bedside in psychosocial
  • Recording an objective severity band in the case notes
  • Deciding when a total crosses the threshold for escalation
  • Re-scoring to track whether a child is improving or deteriorating
  • Checking the exact criteria of a score used infrequently

3 Formula & method

The score sums 8 criteria: Recurrent excessive distress when anticipating or experiencing separation from home/attachment figures; Persistent excessive worry about losing major attachment figures or harm to them; Persistent excessive worry about an event causing separation (getting lost, kidnapped, ill); Persistent reluctance or refusal to go out, to school or elsewhere because of separation fear; Persistent excessive fear of being alone or without attachment figures; Persistent reluctance or refusal to sleep away from home or without an attachment figure nearby; Repeated nightmares involving the theme of separation; Repeated physical complaints (headache, stomach ache, nausea) when separation occurs or is anticipated. Totals are then banded: any score - Below threshold: fewer than 3 criteria endorsed; 3 criteria met or more - Threshold met: ≥3 criteria, lasting ≥4 weeks in children/adolescents, with significant distress or impairment.
  • DSM-5 threshold: 3 or more of the 8 criteria listed.
  • A diagnosis also requires clinically significant distress or impairment, the required duration, and exclusion of substance use or another condition. Screening aid only - not a diagnosis.

4 Frequently asked questions

How many criteria does the Separation Anxiety Disorder use?

8. They are Recurrent excessive distress when anticipating or experiencing separation from home/attachment figures; Persistent excessive worry about losing major attachment figures or harm to them; Persistent excessive worry about an event causing separation (getting lost, kidnapped, ill); Persistent reluctance or refusal to go out, to school or elsewhere because of separation fear; Persistent excessive fear of being alone or without attachment figures; Persistent reluctance or refusal to sleep away from home or without an attachment figure nearby; and others.

What do the bands of the Separation Anxiety Disorder mean?

The total is interpreted as: any score - Below threshold: fewer than 3 criteria endorsed; 3 criteria met or more - Threshold met: ≥3 criteria, lasting ≥4 weeks in children/adolescents, with significant distress or impairment.

Does the score replace clinical judgement?

No. It is a structured way to record and communicate severity. A clinician concerned about a child should act on that concern regardless of the total.

Where does this score come from?

DSM-5 threshold: 3 or more of the 8 criteria listed.

Does it work offline?

Yes. Score definitions are bundled with the PediAid app, so the score computes without a connection.
