The CASTER™ is a screening tool for identifying trauma exposure and responses for children and youth early in the assessment and treatment process. It has been designed for mental health and allied professionals with training and experience in childhood trauma. The CASTER was designed in consultation with youth, parents, and experts in trauma. ©2021 The George Hull Centre
Trauma screening is designed to be administered to every child within a given system to determine whether they should be referred for a comprehensive trauma-informed mental health assessment.
Trauma screening should evaluate the presence of two critical elements:
1. Exposure to potentially traumatic events/experiences, including traumatic loss
2. Traumatic stress responses/symptoms
Trauma screening should measure a wide range of experiences, identify common responses and symptoms of trauma, as well as other commonly reported difficulties.
There are 3 versions of the CASTER available at this time. It is recommended that users read the Administration Guide prior to use.
Parent/Caregiver Report (Children ages 0-5)
Parent/Caregiver Report (Children and Youth ages 6-18)
Self-Report (Youth ages 12-18)
All versions are available in French and Spanish, including the Administration Guide.
It is recommended that users read the Administration Guide prior to use.
The CASTER is designed for mental health professionals with training and experience in childhood trauma. The CASTER is typically used in clinical mental health services.
Ideally, both youth and parent/caregiver complete the CASTER for youth aged 12–18.
The circumstances under which the CASTER may not be appropriate include:
The CASTER is a screening tool and should be completed as part of the initial assessment process. It is important to have the necessary consent and rapport established to allow for safety to explore this sensitive material.
Youth or parent/caregivers should only fill out a double-sided printed version of the form (not a photocopied version). A photocopy does not capture shaded distinctions between the rows of items and may lead to completion errors.
Youth may disclose experiences and/or concerns on this form that they may not feel comfortable sharing in the presence of their parent/caregivers; therefore, youth and parent/caregivers should be given separate and private spaces to complete the CASTER.
Some youth or parents/caregivers may need additional support from the clinician to complete the form.
Given the sensitive nature of the questions, the CASTER should be completed within a clinical setting with the support of a clinician. Youth and parents/caregivers should be provided separate and private spaces to complete the CASTER. They should be provided with as much time as needed for completion.
The clinician should be available to provide support and answer questions, if necessary.
Before the youth/parent/caregiver leaves the meeting, the clinician should review the CASTER to make sure that it is complete and leave time to debrief with the respondent. The clinician should review any incomplete items to determine if there are questions and assist with completion where appropriate.
The youth or parent/caregiver may have disclosed information whereby the clinician has a duty to report or otherwise act on the information provided as per applicable laws or ethical standards.
The following items are critical items that may require immediate action:
Section ONE:
Section TWO
A youth or parent/caregiver may choose not to complete the CASTER. For their records, agencies may want to note that the youth or parent/caregiver declined to complete the CASTER. The youth or parent/caregiver may be offered another opportunity to complete the CASTER, if appropriate.
There are several reasons that all the questions may not be completed. The clinician should review the items that have not been completed with the youth/parent/caregiver to determine if they did not understand the question, were unsure how to fill it out, or were not comfortable answering. If the client feels that they can then answer the question, they should do so.

The CASTER is NOT a comprehensive clinical assessment and does not screen for all types of trauma exposure nor all traumatic stress reactions.
