Abstract

Background: The recently published ICD-11 includes substantial changes to the diagnosis of 10 posttraumatic stress disorder (PTSD) and introduces the diagnosis of Complex PTSD (CPTSD). The International Trauma Interview (ITI) has been developed for clinicians to assess these new diagnoses but has not yet been evaluated. Objectives: To evaluate the psychometric properties of the Swedish translation of the ITI by examining the interrater agreement, latent structure, internal consistency, and convergent and discriminant validity. Methods: In a prospective study, 186 adults who had experienced a potentially traumatic event were assessed with the ITI and answered questionnaires for symptoms of posttraumatic stress, other psychiatric disorders, functional disability, and quality of life (QoL). Results: The diagnostic rate was 16% for PTSD and 6% for CPTSD. Interrater agreement was satisfactory (α =.76), and confirmatory factor analysis indicated that a two-factor second-20 order model consistent with the ICD-11 model of CPTSD provided acceptable fit to the data. Composite reliability analysis demonstrated that the ITI possessed acceptable internal reliability, and associations with measures of other psychiatric disorders, insomnia, functional disability, and QoL supported the concurrent validity of the ITI. Conclusion: Swedish ITI shows promise as a clinician-administered instrument to assess and diagnose ICD-11 PTSD and CPTSD.

Objetivos: La recientemente publicada CIE-11 incluye cambios sustanciales al diagnóstico de Trastorno de Estrés Postraumático (TEPT) e introduce el diagnóstico de TEPT Complejo (TEPT-C). La Entrevista Internacional de Trauma (ITI, por su sigla en inglés) ha sido desarrollada para que los clínicos examinen estos nuevos diagnósticos pero no ha sido evaluada aún. El objetivo de este estudio fue evaluar las propiedades psicométricas de la traducción sueca de la ITI, examinando el acuerdo inter-evaluador, estructura latente, consistencia interna y validez convergente y discriminante.Métodos: En un estudio prospectivo, 186 adultos que habían experimentado un evento potencialmente traumático fueron evaluados con la ITI y respondieron cuestionarios de síntomas de estrés postraumático, otros trastornos psiquiátricos, discapacidad funcional y calidad de vida (QoL, por su sigla en inglés).Resultados: Las tasas de diagnóstico fueron 16% para TEPT y 6% para TEPT-C. El acuerdo inter-evaluador fue satisfactorio (α = .76), y el análisis factorial confirmatorio indicó que un modelo de dos factores, de segundo orden, consistente con el modelo de la CIE-11 para TEPT-C proporcionó ajuste aceptable a los datos. El análisis compuesto de confiabilidad demostró que la ITI posee consistencia interna aceptable, y las asociaciones con medidas de otros trastornos psiquiátricos, insomnio, discapacidad funcional y QoL respaldaron la validez concurrente de la ITI.Conclusión: La ITI sueca se muestra promisoria como un instrumento administrado por los clínicos para evaluar y diagnosticar TEPT y TEPT-C según la CIE-11.

目的:最近公布的ICD-11对创伤后应激障碍(PTSD)诊断进行了重大修改,并引入了复杂型PTSD(CPTSD)的诊断。国际创伤访谈(ITI)可以为临床医生使用于评估这些新的诊断,但尚未得到评估。本研究的目的是通过考察评分者一致性、潜在结构、内部一致性、聚合和区分效度来评估瑞典语版本ITI的心理测量属性。方法:在一项前瞻性研究中,对186名经历过可能创伤事件的成年人进行了ITI评估,并回答了创伤后应激和其它精神疾病、功能障碍和生活质量(QoL)症状的问卷。结果:PTSD的诊断率为16%,CPTSD的诊断率为6%。 评分者一致性达到满意(.76),验证性因素分析表明,与ICD-11 CPTSD的模型一致的双因素二阶模型提供了可接受的数据拟合。综合分析表明,ITI具有可接受的内部一致性。ITI与其他精神疾病、失眠、功能障碍和QoL的关联性支持ITI的聚合效度。结论:瑞典语版本ITI是一个使用于评估和诊断ICD-11 PTSD和CPTSD的有效临床工具。.
