The Thomas Test is a cartoon-based instrument that measures the prevalence of PTSD in children between the ages of 6 and 12 who have experienced one or more traumatic events.
The test was developed by the Danish Center for Psychotraumatology with inspiration from Dr Richard Neugebauer's similar English test 'Darryl'. The test is also available in Greenlandic 'Miki' and Arabic 'Sami'.
The test was first used on a group of children from Seest, Denmark who experienced the fireworks disaster on 3 November 2004. The Danish Center for Psychotraumatology has subsequently developed other versions and currently has 6 different variants: violence, illness, sexual assault, refugee, fire and death.
The test itself can only be scored by a psychologist, but it can be administered by other relevant professionals.
