Adaptation of the questionnaire "Ιnternational trauma questionnaire – child/adolescent version" to a greek adolescent population: preliminary findings
Summary:
Background: The International Trauma Questionnaire and its version for Children and Adolescents (ITQ-CA) is a new self-report assessment tool focused on the core impact of Post Traumatic Stress Disorder (PTSD) and Complex Post Traumatic Stress Disorder (CPTSD). The questionnaire is widely used in Anglophone countries, and expanding its use in Greece requires prior validation in the Greek population.
Objective: This research aims to validate the ITQ-CA in the general population of adolescents aged 15-17 years, particularly in relation to the psychological effects of the COVID-19 pandemic in Greece.
Methods: The Greek "International Trauma Questionnaire Child/Adolescent version" was administered to a non-clinical adolescent population in Greece. The final sample consisted of 150 Greek adolescents (51.3% girls), with a significant percentage (30%) meeting the criteria for PTSD according to both the Harvard Trauma Questionnaire and the ITQ-CA. Adolescents aged 15-17 years were recruited via convenience sampling through an online Google platform. Participants completed the "International Trauma Questionnaire Child/Adolescent version," the "Harvard Trauma Questionnaire," and the Greek version of the "Strengths and Difficulties Questionnaire" (SDQ-Hel). Confirmatory factor analysis, Cronbach’s alpha, and correlation coefficients were used to test the psychometric properties of the ITQ-CA.
Results: Confirmatory factor analysis using a maximum likelihood procedure yielded equivocal results for the seven survey models, indicating that the 6-factor model provided the optimal fit. Reliability coefficients were greater than 0.7, indicating acceptable reliability. The correlation of the ITQ-CA with the Harvard Trauma Questionnaire was statistically significant, confirming the convergent validity of the ITQ-CA. Adolescents diagnosed with PTSD based on the Harvard scale scored higher on all PTSD dimensions of the ITQ-CA, confirming the questionnaire's discriminative capacity. The percentage of the sample with PTSD was significantly higher among girls and 15-year-old adolescents.
Conclusion: The Greek "International Trauma Questionnaire Child/Adolescent version" (ITQ-CA), despite the ambiguous results from the confirmatory factor analysis, demonstrated acceptable reliability coefficients and convergent validity indices. Additionally, the ITQ-CA exhibited significant discriminative ability, effectively distinguishing adolescents with PTSD from those without, as validated against the Harvard scale, used as the "gold standard." Further research is necessary to enhance the validation of the Greek ITQ-CA questionnaire.
