Abstract
Recently, the ICD-11 has updated the diagnostic requirements for dissociative identity disorder (DID) and introduced partial DID as a new diagnosis. This study validated the first measure of DID and partial DID as defined in ICD-11. Two convenience samples of mental health service users (118 Chinese speakers and 115 English speakers) completed the International Dissociative Identity Disorder Questionnaire (IDIDQ), the Dissociative Experiences Scale-Taxon (DES-T), and the Multiscale Dissociation Inventory (MDI) in their respective language. The IDIDQ had good to excellent internal consistency (α =.861 to.892) and test-retest reliability (ICC =.682 to.854, p < .001) in both samples. The 3-factor structure of DID (i.e., amnesia, dissociative identities, and switching), as proposed in ICD-11, was supported by our cross-cultural data, with configural, metric and scalar invariance established across the Chinese- and English-speaking samples. The IDIDQ reliably detected probable ICD-11 DID and partial DID (κ =.517 to.781, p < .001) during a one-week test-retest period. The IDIDQ subscales were strongly correlated with the respective MDI subscales and the DES-T scores. The IDIDQ results had moderate to substantial agreement with the MDI Identity Dissociation subscale and the DES-T in both samples (κ =.514 to.741, p < .001). This study provides first evidence showing the ICD-11 DID and partial DID can be reliably and validly measured using the IDIDQ.
期刊介绍:
The Asian Journal of Psychiatry serves as a comprehensive resource for psychiatrists, mental health clinicians, neurologists, physicians, mental health students, and policymakers. Its goal is to facilitate the exchange of research findings and clinical practices between Asia and the global community. The journal focuses on psychiatric research relevant to Asia, covering preclinical, clinical, service system, and policy development topics. It also highlights the socio-cultural diversity of the region in relation to mental health.
