Before you begin

Use this public-domain child/adolescent self-report only in a qualified, consented, safeguarding-aware workflow. Ask the young person to keep the upsetting or stressful event private and in mind; do not enter identifying event details here.

Answer review
International Trauma Questionnaire (ITQ) Complete the finalized ITQ and review PTSD and DSO symptom scores with the published algorithm and a provisional PTSD/CPTSD pattern.
International Trauma Questionnaire with Clinical Checks (ITQ-CC) Complete the public-domain ITQ-CC with conditional clinical checks, two symptom totals, and a provisional PTSD or CPTSD requirement trace.
International Adjustment Disorder Questionnaire (IADQ) Complete the 19-item IADQ to review symptom severity and its five-requirement probable-pattern algorithm with private in-tab processing.
International Prolonged Grief Questionnaire (IPGDS) Record 14 past-week grief responses and review the 13-item severity sum, impairment, and cultural context without applying a diagnostic cutoff.

Trauma questions for a child or adolescent require more than age-appropriate wording. Consent and assent, privacy, emotional readiness, safeguarding, and a clear plan for follow-up all affect whether administration is responsible. A score cannot replace the adult judgment needed when a young person becomes distressed or discloses a safety concern.

The International Trauma Questionnaire — Child and Adolescent Version (ITQ-CA) is intended for ages 7–17. It asks about the past month after an upsetting or stressful event has been identified privately. The form contains twelve symptom items and two five-area functional-impairment blocks, for 22 responses in total. Identifying details about the event are not needed and should not be entered.

Symptom groupTwo-item domainsRelated impairment block
PTSDRe-experiencing, avoidance, and current threatFive life areas affected by PTSD symptoms
Disturbances in self-organizationAffect regulation, negative self-concept, and relationship disturbanceFive life areas affected by self-organization symptoms

The questionnaire provides symptom sums and a trace of the published domain-and-impairment algorithm. The International Trauma Consortium advises that total-score cutoffs should not be used; the rule depends on whether each required domain contains a present symptom and whether at least one related area of life is impaired. The possible trace statuses are CPTSD requirements met, PTSD requirements met, or neither.

These labels describe a self-report response pattern, not a diagnosis. A qualified professional must consider whether the event and symptoms were understood correctly, developmental context, duration, other conditions, impairment, exclusions, and current safeguarding needs. The form does not contain a direct self-harm or emergency item, so a questionnaire result cannot clear an independent safety concern.

Administration should occur only in a consented clinical or research workflow with a responsible adult or qualified professional able to pause, support, and follow up. It is unsuitable for unsupervised self-diagnosis, school discipline, placement, selection, eligibility, or safety clearance.

How to Use This Tool:

Confirm the young person is aged 7–17, has appropriate consent and assent, and has immediate human support available before starting.

  1. Identify the relevant upsetting or stressful event privately. Ask the young person to keep it in mind without typing names, locations, or other identifying details.
  2. Select Start assessment and complete the twelve symptom items for the past month. Pause when wording is unclear or distress rises; do not coach an answer to make a criterion pass or fail.
  3. Answer the ten Yes-or-No impairment questions for the two symptom groups. Every one of the 22 responses is required before the algorithm can be traced.
  4. Review the questionnaire algorithm status, the six domain maxima, and both impairment counts with a qualified professional. Use the symptom totals only as dimensional descriptions.

Interpreting Results:

A symptom is present for the questionnaire algorithm when its response is greater than or equal to 2. Each of the three PTSD domains needs at least one present symptom, and at least one of the five PTSD-related life areas must be impaired. The self-organization group uses the same structure across its three domains and five impairment areas.

StatusResponse pattern shownRequired follow-up
CPTSD requirements metAll PTSD and self-organization domain conditions plus both impairment conditions are present.Qualified assessment; the status is not a diagnosis.
PTSD requirements metAll PTSD domain and impairment conditions are present, but the full CPTSD rule is not.Qualified assessment; the status is not a diagnosis.
NeitherThe complete PTSD rule is not present, even if some symptoms or self-organization conditions are endorsed.Review distress, functioning, and safety rather than assuming no support is needed.

Do not infer a status from the 0-to-48 total symptom score. A high sum can miss one required domain or impairment condition, while a lower sum can still satisfy the literal algorithm. The criterion trace is the relevant output for the rule.

Technical Details:

Items 1–12 use direct integer codes from 0 to 4 and are grouped into six consecutive two-item domains. Items 13–22 use No = 0 and Yes = 1 for two five-area impairment blocks. No item is reverse-scored, weighted, imputed, or normalized.

Formula Core:

The two dimensional symptom scores sum six items each, and the total symptom score adds all twelve. Impairment counts sum the five binary responses associated with each symptom group.

TPTSD=∑i=16xi , TDSO=∑i=712xi Tall=TPTSD+TDSO IPTSD=∑i=1317xi , IDSO=∑i=1822xi
ScoreItemsRange
PTSD symptom score1–60 to 24
Self-organization symptom score7–120 to 24
Total symptom score1–120 to 48
PTSD impairment count13–170 to 5
Self-organization impairment count18–220 to 5

Rule Core:

For each two-item domain, the higher of the two responses is compared with the inclusive threshold of 2. The final status follows an ordered, mutually exclusive rule.

Rule stageExact condition
PTSD domain conditionThe maximum response is greater than or equal to 2 in re-experiencing, avoidance, and current threat.
PTSD impairment conditionAt least one of Items 13–17 equals 1.
Self-organization domain conditionThe maximum response is greater than or equal to 2 in affect regulation, negative self-concept, and relationship disturbance.
Self-organization impairment conditionAt least one of Items 18–22 equals 1.
CPTSD statusAll PTSD and self-organization domain and impairment conditions are true.
PTSD statusThe PTSD conditions are true and the complete CPTSD rule is false.
Neither statusThe complete PTSD conditions are false.

All calculations use the literal response codes. There is no total-score cutoff, percentile conversion, norm lookup, intermediate rounding, or second diagnostic path.

Safeguarding, Limitations, and Privacy:

The ITQ-CA does not verify trauma exposure, comprehension, duration, differential diagnosis, developmental appropriateness, caregiver context, or immediate safety. A responsible administrator must respond to distress or disclosure independently of the score and follow the safeguarding procedures for the setting and jurisdiction.

Responses remain in the current browser tab. They are not written into the URL, shared through a response-bearing link, transmitted, or stored by the assessment. Starting over or reloading clears the session; downloaded or copied records still require appropriate protection.

If a young person may be in immediate danger or at risk of harm, stop the questionnaire and follow local safeguarding and emergency procedures. Do not wait for an algorithm status.
