Using the International Trauma Questionnaire (ITQ) in Diverse Global Populations

The International Trauma Questionnaire (ITQ) was developed based on the criteria for posttraumatic stress disorder (PTSD) and complex posttraumatic stress disorder (CPTSD) as outlined in the International Classification of Diseases, 11th ed. (ICD-11) (Cloitre et al., 2018). The ICD-11 is a covers physical and mental health illnesses and serves as a diagnostic guide and is widely used worldwide (World Health Organization [WHO], 2019). The ITQ has been translated and utilized within many populations and cultures. This is in contrast to the 5th edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-V), the primary diagnostic manual used for mental disorders in the U.S. (American Psychological Association [APA], 2009). The literature on the ITQ’s use within cultures in the Middle East, Africa, and Asia will be examined.

The ITQ is an instrument which measures an individual’s level of PTSD and CPTSD. It is brief, easy to understand, and is designed for individuals to be able to fill it out themselves (Cloitre et al., 2018). It was developed to serve as a diagnostic tool, because the ICD-11 uses a narrative description of symptoms format rather than specific diagnostic criteria. The development of the ITQ focused on inclusion of questions which addressed the core symptoms, rather than every possible symptom. The majority of the questions use a Likert scale of 1-5. An individual taking the assessment can be diagnosed with PTSD or CPTSD, but not both. Early analyses of the ITQ found some questions to have poor reliability, so they were removed or changed. Additionally, the ITQ was found to work well within both community and clinical populations. The ITQ has been translated into at least 28 languages, has a version for children and adolescents, and is freely available in the public domain (The International Trauma Consortium, n.d.). The ITQ has been found to be valid and reliable among many populations internationally, however, additional adaptations to match cultural context and idioms of distress could be useful in capturing the true experience of trauma for many populations.

In the Middle East, a study of Syrian refugees in Lebanon (Vallieres et al., 2018) tested the use of the ITQ and the ICD-11 in their accuracy in measuring PTSD and CPTSD within this group. They found that CPTSD was more common than PTSD, and there were high amounts of traumatic exposure. The most distressing events as rated by participants were the deaths of loved ones, being separated from family and friends, forced displacement, and bombings. Overall, participants found that the ITQ seemed to accurately reflect their experiences. Limitations of the ITQ were that it lacked any questions related to somatic symptoms such as amnesia and poor concentration (Vallieres et al., 2018), or fainting, dizziness, weakness, and chronic pain, all of which are common cultural idioms of mental and emotional distress for Syrians (Barkil-Oteo et al., 2018). Another issue is that some participants showed hesitancy in answering, exhibiting signs of paranoia and hypervigilance. To address this, trust and rapport may first need to be built with the person administering the ITQ. However, the use of the ITQ helped create a language and normalization for participants and assisted them in opening up in subsequent therapy sessions (Vallieres et al., 2018). Overall, both the ICD-11 and the ITQ were found be culturally viable within this population in this study.

In Africa, Owczarek et al. (2019) tested the ITQ among community members in Kenya, Ghana, and Nigeria. In this study, the ITQ was found to be a valid assessment within these different cultural populations, with a very good internal consistency. There were some differences in the types of traumatic exposures between the countries, as well as levels of PTSD and CPTSD. The limitations described by the authors discuss the lack of generalizability, as the sample demographics were different from the general population, such as having a much higher rate of higher education, which has been shown to be correlated with lower levels of PTSD symptoms. Additionally, the data collection was done online, limiting access. Another study by Barbieri et al. (2019) compared the rates of PTSD and CPTSD between the DSM-V and the ITQ in a clinical sample of African refugees in Italy. 79% of the participants met the criteria for PTSD using the DSM-V. Using the ITQ, 38% met criteria for PTSD and 30% for CPTSD, with a combined total of 68%, showing a statistically significant difference compared to the DSM-V. Understandably, this population of treatment-seeking refugees showed much higher rates of both PTSD and CPTSD than in the study of community members by Owczarek et al. (2019), but it also found the ITQ to be a valid measure for this population (Barbieri et al., 2019).

Examining the ITQ in Asia, Tian et al. (2020) found that the assessment had good validity and reliability among Chinese young adults. They found that the rate of CPTSD was significantly higher at 13.35% as compared to PTSD at 5.85%. One possible explanation is the high rate of childhood maltreatment in China, and early trauma exposure is a major risk factor for CPTSD, in addition to other cultural factors. This study also measured posttraumatic growth (PTG), a heightened state of resilience. PTG was lower among those with CPTSD symptoms than those with PTSD only. Limitations of this study were also a lack of generalizability due to the narrowness of the sample, and that all participants had experienced at least one traumatic event. Another study examined the validity of the ITQ in young adults across multiple Asian cultures – China, Hong Kong, Japan, and Taiwan (Ho et al., 2020). This study also found that PTSD and CPTSD were valid separate diagnoses using the ITQ within these populations, and the association of increased childhood negative experiences (though not necessarily traumatic) correlated with higher rates of CPTSD. This study also found higher rates of CPTSD than PTSD, like Tian et al. (2020).

From these studies, it appears that the ITQ is indeed valid across multiple populations in determining PTSD and CPTSD, and validating the legitimacy of these two related, but different, diagnoses. Despite initial impressions that there should be more specific cultural adaptations more than language translations, these studies show that symptomology of these disorders remains in similar clusters cross-culturally. Still, there is a continued question of if these results would shift if the questions were adapted to use the specific cultural idioms and expressions of emotional distress. As there do not appear to be any studies which modify the ITQ in such a way, there is no current way to compare this.
