Research Design on Drug Abuse in Sierra Leone
Research Question: What are the prevalence, risk factors, and consequences of drug abuse in Sierra Leone?
Essential Elements:
1. Study Design:
- Cross-sectional survey: To measure the prevalence and risk factors of drug abuse at a specific point in time.
- Case-control study: To identify factors associated with drug abuse by comparing drug users to controls.
- Longitudinal study: To track changes in drug use and its consequences over time.
2. Sample:
- Target population: Individuals aged 15-64 years in Sierra Leone.
- Sample size: Determined using statistical power analysis based on the research question, effect size, and acceptable level of error.
- Sampling method: Probability sampling (e.g., stratified random sampling) to ensure representation of the population.
3. Data Collection:
- Self-report questionnaires: To collect information on drug use, risk factors, and consequences.
- Biological samples (e.g., hair, urine): To confirm drug use and assess patterns of use.
- Focus groups and interviews: To gather qualitative data on experiences, motivations, and perceptions related to drug abuse.
4. Variables:
- Dependent variables:
- Drug use (frequency, type, duration)
- Consequences of drug use (e.g., health problems, social isolation)
- Independent variables:
- Socioeconomic factors (e.g., poverty, education)
- Environmental factors (e.g., peer influence, availability of drugs)
- Psychological factors (e.g., stress, depression)
5. Data Analysis:
- Descriptive statistics: To summarize the prevalence and patterns of drug abuse.
- Inferential statistics: To test hypotheses about risk factors and consequences.
- Logistic regression: To identify significant predictors of drug abuse.
- Structural equation modeling: To examine complex relationships between variables.
6. Ethical Considerations:
- Informed consent: Obtain consent from participants after providing clear information about the study.
- Confidentiality: Protect the privacy and anonymity of participants.
- Potential harm: Minimize risks to participants and ensure access to support services if needed.
7. Report:
- Present the findings in a scientific manner, including tables, graphs, and interpretation.
- Discuss the implications for policy and intervention development.
