Psychiatry: practice, law & professional skills
Research methods & the dissertation
Research methods teach how psychiatric knowledge is created: designing studies, collecting and analysing data, and writing up results. In Malaysia, specialist trainees usually complete a research dissertation as part of the Master of Medicine (Psychiatry).

What is it?
Every treatment and guideline in psychiatry rests on research. Psychiatrists need to know how studies are designed, from surveys and case-control studies to randomised controlled trials, and what can go wrong.
In Malaysian Master of Medicine (Psychiatry) programmes, trainees typically complete a dissertation: they choose a question, write a proposal, obtain ethics approval (for MOH sites, through the Medical Research and Ethics Committee and the National Medical Research Register), collect and analyse data, and write a thesis that is examined.
Common dissertation topics include prevalence of depression in a patient group, validation of a questionnaire in Bahasa Malaysia, or factors linked to treatment outcomes.
Why does a psychiatrist need it?
Doing research teaches psychiatrists to think critically, understand evidence and contribute local knowledge. Malaysia needs research on its own population, languages and cultures rather than relying only on data from elsewhere.

What are the key topics?
Study designs
- Descriptive studies: case reports, case series, cross-sectional surveys
- Analytical observational studies: case-control and cohort
- Randomised controlled trials and blinding
- Systematic reviews and meta-analysis
- Qualitative research: interviews, focus groups, thematic analysis
- Validation studies of rating scales and translations
Statistics
- Descriptive statistics and distributions
- Hypothesis testing, p-values and confidence intervals
- t tests, chi-square, correlation, regression
- Sample size and power calculations
- Reliability (kappa, Cronbach's alpha) and validity
- Software such as SPSS, R or Stata
Research ethics and governance
- Informed consent and vulnerable participants
- Research ethics committee approval (e.g. MREC for MOH facilities)
- National Medical Research Register (NMRR) registration
- Data protection and confidentiality
- Good Clinical Practice (GCP)
The dissertation
- Choosing a feasible question
- Literature review
- Writing a proposal and timeline
- Data collection and management
- Analysis and interpretation
- Writing the thesis and viva examination
- Publishing and presenting results
How is it learned and assessed?
- Epidemiology and biostatistics in pre-clinical years; student research projects in some medical schools
- Dissertation requirement in Malaysian MMed (Psychiatry) programmes, typically submitted before or around the final (Part II) examination
- MRCPsych Paper B tests research methods and statistics through critical review questions
- Good Clinical Practice courses for those joining trials
Typical textbooks and resources
- Medical Statistics at a Glance — Petrie & Sabin
- Research Methods in Psychiatry — Freeman & Tyrer (eds.), Royal College of Psychiatrists
- How to Read a Paper — Trisha Greenhalgh
- National Medical Research Register (NMRR) guidance for MOH research

Common questions
Do psychiatry trainees in Malaysia have to write a thesis?
Typically yes. Master of Medicine (Psychiatry) programmes usually require a research dissertation, which is examined alongside the clinical examinations. Exact rules vary by university, so check the programme handbook.
Why must doctors learn statistics?
Because they need to judge whether research results are real and relevant before applying them to patients. Basic statistics helps avoid being misled by weak or biased studies.
