Brief Summary
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.

Study Arms (2)
CIDI-5
For the CIDI-5 group, respondents will directly partake in the CIDI-5 interview without responding to any inquiries regarding their life history.
LHC-CIDI-5
For the LHC-CIDI-5 group, respondents, before initiating the CIDI-5, will begin with LHC, completing a calendar by answering questions about important personal experiences since birth until the interview year.
Interventions
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) . Trained interviewers will administrate selected modules from the Hong Kong version of the CIDI-5 in a computer-assisted personal interview to measure the outcomes.
The interviewer will start by asking the respondent's age and significant personal experiences, which is expected to take 15 minutes. Remembering and recording the experiences provide cognitive engagement and information which can further serve as memory cues for respondents in the following screening of CIDI-5. Subsequently, the respondents will proceed to the screening section for CIDI-5 and will refer to the completed calendar from the LHC section when they are asked to report lifetime experience or age-of-onset for mental disorders. Trained interviewers will conduct all interviews in a computer-assisted personal interview. To validate the diagnoses in the LHC-CIDI-5 group, clinical re-interviews for MDD, GAD, and PTSD will be conducted by a trained mental health professional with previous experience using DSM-5.
Eligibility Criteria
This study is a sub-study of the District Health Profile (DHP), which is a district-level representative descriptive cross-sectional study. In DHP, 1% of households in selected Hong Kong districts will be randomly selected from the Census and Statistics Department's list of quarters, with stratification based on districts and housing types; all persons aged 18 and above in the recruited households will be included and surveyed. For participants who consent to join the DHP study, a sub-sample of 2,500 participants aged 25 or above will be randomly selected and assigned to two groups through a random process. All 2,500 individuals will complete the survey for the DHP study, including the CIDI-5 section. When administering the CIDI-5, one group of 1,250 individuals will be interviewed using only the CIDI-5, while the other group of 1,250 individuals will be interviewed with LHC first, followed by the CIDI-5.
You may qualify if:
- All household members aged 25 years old and over are randomly sampled from the Census and Statistics Department List of Quarters
- Live in the address sampled from the Census and Statistics Department List of Quarters
- Reside in Hong Kong for at least six months in the past year
- Able to read and communicate in Chinese or English
- Without linguistic or cognitive difficulties
You may not qualify if:
- Domestic workers
