Evidence-based early intervention for PTSD and dissociative symptoms
Andy Fung’s trauma-informed, dissociation-specific online psychoeducation program is one of only two interventions worldwide supported by randomized controlled trials for trauma-related dissociation. It is also the first and only established early intervention (psychoeducation) for PTSD symptoms in Hong Kong.
Assessments for trauma and dissociation
Andy Fung has led a number of psychometric studies validating trauma-related assessment tools in Hong Kong, Taiwan, and across cultures. These include, but are not limited to, the Chinese version of the PTSD Checklist for DSM-5 (PCL-5) and the Chinese version of the Dissociative Experiences Scale-Taxon (DES-T).
He also led the development and validation of the International Dissociative Identity Disorder Questionnaire (IDIDQ), which is the first and only validated self-report measure of ICD-11 DID and partial DID. The IDIDQ was co-developed with Vedat Şar (an official advisor to the DSM-5 Task Force of the American Psychiatric Association), and Colin A. Ross (the developer of the DDIS). The IDIDQ is structurally similar to the International Trauma Questionnaire (ITQ) and the International Adjustment Disorder Questionnaire (IADQ). It assesses the three factors of DID proposed in ICD-11: amnesia, dissociative identities, and switching. The IDIDQ was designed to be an easy-to-use tool that can facilitate screening and cross-cultural research.
Advocating for public health and professional awareness of trauma and dissociation since the 2012
He founded the Hong Kong Association Concerning Dissociative Disorders (HKACDD) as an online unofficial organization in 2012 and has remained active in promoting social awareness of trauma, child protection, PTSD, and dissociative disorders. He has consistently argued that trauma and dissociation should be regularly taught in mental health professional curricula.
