LHC-CIDI-5 in Hong Kong

The World Health Organization Composite International Diagnostic Interview-5th (CIDI-5) is a standardized diagnostic tool used to assess the prevalence of mental and substance use disorders over varying time frames (30 days, 12 months, and lifetime) based on the diagnostic criteria outlined in the Diagnostic and Statistical Manual of Mental Disorders 5th edition (DSM-5) and International Classification of Diseases 10th edition (ICD-10). However, retrospective measurements like the CIDI-5 are susceptible to recall bias, especially for the lifetime experience, which can hinder the reporting accuracy with mental disorders. To mitigate this issue, the life history calendar (LHC) was introduced as an aid to assist respondents in recalling the timing of life events, enhancing the ability of the CIDI-5 to measure the lifetime prevalence of mental disorders. The LHC is a grid structure with columns representing time units and rows representing life domains under study. In a study conducted in Nepal, combining the CIDI-5 with the LHC resulted in a significant increase in the detection of mental disorders compared to using the CIDI-5 alone. This approach did not lead to an increase in false positives after clinical validation. This experiment aims to adapt a Hong Kong version of the LHC based on the Nepalese model and evaluate the effectiveness of the LHC-assisted CIDI-5 (LHC-CIDI-5) compared to the CIDI-5 alone in assessing mental disorders.

Safety Plan in Emergency Department to Prevent Suicidal Attempt Recidive

Suicide is one of the leading causes of death worldwide, with more than 700 000 deaths due to suicide every year, according to the World Health Organisation (WHO). In France, mortality rate by suicide is 17% higher than the European average; moreover, around 7% if the population (aged 18-75 years old) attempted suicide in their life. Since years 2000, a series of preventative interventions have been developed to reduce suicide risk, with perhaps the most widely used is suicide safety planning. Several studies showed positive results after evaluating the efficacy of suicide safety planning for reducing patient risk. However, this intervention hasn't been yet evaluated in French emergency department settings. Safety planning is a collaborative intervention between a therapist and the patient, by which a series of preventive actions are planned in the event patient experiences suicide ideation. Patients are provided with a paper form of the completed safety plan, including the following: personal warning signs, self-management strategies, reasons for living, social supports, and crisis supports. In this study, we aim to assess the feasability and the acceptabilty of using the safety plan among patients hospitalised in a short-term unit, after an emergency department admission for suicidal attempt.
