Who the test is designed for

      • Adults (age 18+) judged to have an IQ in the normal range (IQ >=85).
      • Versions for adolescents and children are also available.

Versions & translations

Taking the test

The ITQ consists of 18 items, giving you 5 choices for each item:

      1. Not at all = 0 points
      2. A little bit = 1 point
      3. Moderately = 2 points
      4. Quite a bit = 3 points
      5. Extremely = 4 points

The ITQ comprises 18 items, broken down into four categories:

      • 9 questions on responses to traumatic or stressful events (PTSD)
      • 3 questions on the affects of those responses (PTSD)
      • 6 statements on how true a statement is of you (CPTSD)
      • 3 questions on those beliefs and emotions (CPTSD)

Scoring

1. Diagnostic scoring for PTSD and CPTSD

PTSD

  • If P1 or P2 > 2 criteria for Re-experiencing in the here and now (Re_dx) met
  • If P3 or P4 > 2 criteria for Avoidance (Av_dx) met
  • If P5 or P6 > 2 criteria for Sense of current threat (Th_dx) met

AND

  • At least one of P7, P8, or P9 > 2 meets criteria for PTSD functional impairment (PTSDFI)
  • If criteria for ‘Re_dx’ AND ‘Av_dx’ AND ‘Th_dx’ AND ‘PTSDFI’ are met
  • Then criteria for PTSD are met.

CPTSD

  • If C1 or C2 > 2 criteria for Affective dysregulation (AD_dx) met
  • If C3 or C4 > 2 criteria for Negative self-concept (NSC_dx) met
  • If C5 or C6 > 2 criteria for Disturbances in relationships (DR_dx) met
  • AND
  • At least one of C7, C8, or C9 > 2 meets criteria for DSO functional impairment (DSOFI)
  • If criteria for ‘AD_dx’ AND ‘NSC_dx’ AND ‘DR_dx’, and ‘DSOFI’ are met, the criteria for DSO are met.

Diagnosis

  • PTSD is diagnosed if the criteria for PTSD are met but NOT for DSO.
  • CPTSD is diagnosed if the criteria for PTSD are met AND criteria for DSO are met.
  • Not meeting the criteria for PTSD or meeting only the criteria for DSO results in no diagnosis.

 

2. Dimensional scoring for PTSD and CPTSD.

Scores can be calculated for each PTSD and DSO symptom cluster and summed to produce PTSD and DSO scores.

PTSD

Sum of Likert scores for P1 and P2 = Re-experiencing in the here and now score (Re) Sum of Likert scores for P3 and P4 = Avoidance score (Av)
Sum of Likert scores for P5 and P6 = Sense of current threat (Th)
PTSD score = Sum of Re, Av, and Th

DSO

Sum of Likert scores for C1 and C2 = Affective dysregulation (AD)
Sum of Likert scores for C3 and C4 = Negative self-concept (NSC)
Sum of Likert scores for C5 and C6 = Disturbances in relationships (DR) DSO score = Sum of AD, NSC, and DR

Validity

How reliable, accurate, valid, and up to date is the test?

Dr. Natalie Engelbrecht pointing to the title ‘Discussion’.

Discussion

Natalie:

I disliked having to purposely bring to something upsetting.

I also don’t understand why you can’t have CPTSD without PTSD as that exists in reality.

 

Kendall:

As an experiment, I did the test three times, with three different traumas—from more than 20 years, 5-10 years, and less than six months ago. The results were similar. This experiment was due to the conundrum of identifying the experience that ‘troubles you the most’. The more recent a trauma, the more it impacts my day-to-day functioning, but distant traumas though currently less active in my mind, are no less troubling. Recalling a traumatic event to take the test is an unfortunate necessity.

Dr. Natalie Engelbrecht pointing at a psychometric test.

The ITQ

Briefly describe the experience that troubles you the most, and indicate how long ago it occurred. Then, for items P1–P9, enter your responses concerning its effects during the past month.

Items C1–C9 refer to the ways you typically feel, typically think about yourself, and typically relate to others. Answer them thinking about how true each statement is of you.

Instructions: Please identify the experience that troubles you most and answer the questions in relation to this experience.

Brief description of the experience:
When did the experience occur?
Below are a number of problems that people sometimes report in response to traumatic or stressful life events. Please read each item carefully, then select one to indicate how much you have been bothered by that problem in the past month.
P1. Having upsetting dreams that replay part of the experience or are clearly related to the experience?
P2. Having powerful images or memories that sometimes come into your mind in which you feel the experience is happening again in the here and now?
P3. Avoiding internal reminders of the experience (for example, thoughts, feelings, or physical sensations)?
P4. Avoiding external reminders of the experience (for example, people, places, conversations, objects, activities, or situations)?
P5. Being “super-alert”, watchful, or on guard?
P6. Feeling jumpy or easily startled?
In the past month have the above problems:
P7. Affected your relationships or social life?
P8. Affected your work or ability to work?
P9. Affected any other important part of your life such as parenting, or school or college work, or other important activities?
Below are problems that people who have had stressful or traumatic events sometimes experience. The questions refer to ways you typically feel, ways you typically think about yourself and ways you typically relate to others. Answer the following thinking about how true each statement is of you.
How true is this of you?
C1. When I am upset, it takes me a long time to calm down.
C2. I feel numb or emotionally shut down.
C3. I feel like a failure.
C4. I feel worthless.
C5. I feel distant or cut off from people.
C6. I find it hard to stay emotionally close to people.
In the past month, have the above problems in emotions, in beliefs about yourself and in relationships:
C7. Created concern or distress about your relationships or social life?
C8. Affected your work or ability to work?
C9. Affected any other important parts of your life such as parenting, or school or college work, or other important activities?

Recommended next steps

After the ITQ, consider taking one of the tests below.

Toronto Alexithymia Questionnaire

Measures difficulty in identifying and
describing emotions and feelings

Empathy Quotient

Measures your ability to tune into how someone else
is feeling, or what they might be thinking

Toronto Empathy Questionnaire

Measures your emotional ability to
understand and respond to others.

Online autism tests can play an essential role in the process of self-discovery, and may inform your decision to pursue a formal diagnosis. For a formal assessment, please see a knowledgeable medical professional trained in assessing autism.
