Writing the Problem Statement, Research Objectives and Questions
The problem statement explains the health or knowledge problem, its scale and consequences, the evidence gap and why a study is necessary. Objectives and questions translate that justification into specific work the study will perform.
Learning objectives
- Write a logical, evidence-supported problem statement.
- Differentiate the general objective from specific objectives.
- Construct SMART objectives with measurable verbs.
- Develop aligned research questions and hypotheses.
- Check consistency across title, problem, objectives, variables and methods.
Architecture of a problem statement
- Ideal or expected situation: what should occur according to standards or evidence?
- Actual situation: what is happening, supported by current data?
- Magnitude and distribution: who is affected, where and how often?
- Consequences: clinical, social, economic or health-system effects.
- Existing response: what has already been attempted?
- Knowledge or action gap: what remains unknown or ineffective?
- Study justification: how will the proposed evidence help?
Worked problem-statement example
Topic: missed hypertension follow-up appointments.
Regular follow-up supports blood-pressure control and early detection of complications. Facility X recommends monthly review for adults with uncontrolled hypertension. However, register summaries from January to June 2026 indicate that approximately 41% of scheduled patients did not return within 30 days of their appointment. Missed care may contribute to uncontrolled blood pressure, emergency attendance and avoidable cardiovascular complications. Although staff provide verbal return dates, the relative contribution of travel cost, waiting time, medicine availability, knowledge and reminder systems has not been assessed locally. Without this information, the facility cannot target retention resources effectively. This study will determine the prevalence of missed follow-up and associated factors among adults receiving hypertension care at Facility X.
Weak versus strong statements
| Weak approach | Why weak | Better approach |
|---|---|---|
| “Malaria is a big problem worldwide.” | Vague and unsupported | Use recent evidence for a defined population and location |
| Long background with no gap | Does not justify the study | End with the precise unanswered issue |
| Assumes the cause | Introduces bias | State suspected factors as questions to be investigated |
| Promises to solve everything | Unrealistic | State the evidence contribution accurately |
General objective
The general objective states the overall purpose and closely mirrors the title. Example: To determine the prevalence of missed follow-up appointments and associated factors among adults receiving hypertension care at Facility X in 2026.
Specific objectives
Specific objectives break the general objective into measurable components. Suitable verbs include determine, estimate, describe, compare, assess, identify, explore and evaluate.
- To determine the proportion of scheduled hypertension appointments missed during the study period.
- To assess patient-related factors associated with missed follow-up.
- To examine facility-related factors associated with missed follow-up.
- To explore patient experiences and recommendations regarding continuity of care.
SMART test
Specific
Identifies exactly what will be investigated.
Measurable
Can be answered using defined data.
Achievable
Fits resources, access and competence.
Relevant and time-bound
Addresses the problem within a stated study period.
Research questions
Each question should correspond directly to an objective:
| Specific objective | Research question | Likely analysis |
|---|---|---|
| Determine prevalence | What proportion of appointments is missed? | Frequency, percentage and confidence interval |
| Assess patient factors | Which patient characteristics are associated with missed follow-up? | Cross-tabulation and regression |
| Examine facility factors | How are waiting time and medicine availability related to attendance? | Group comparison and adjusted association |
| Explore experiences | How do patients describe barriers to returning? | Thematic analysis |
Hypotheses
A hypothesis is a testable prediction. H₀: travel time is not associated with missed follow-up. H₁: travel time is associated with missed follow-up. Directional hypotheses should be justified before analysis rather than chosen after results are seen.
Alignment matrix
For every objective, specify: the variable or phenomenon, operational definition, data source, collection method, analysis and expected output. If an objective has no corresponding data or analysis—or data are collected without an objective—the proposal is misaligned.
Common errors
- Writing the solution before demonstrating the evidence gap.
- Using “to know,” “to understand” or “to study” when a measurable verb is possible.
- Including too many objectives for the available time.
- Formulating objectives that require different populations or designs.
- Confusing activities such as “administer questionnaires” with research objectives.
- Using causal language for an observational study.
Applied exercise
Facility data suggest low completion of tuberculosis preventive therapy. Draft: one paragraph stating the ideal, actual situation, magnitude, consequences, current response and gap; one general objective; three specific objectives; corresponding research questions; and one null hypothesis.
Review questions
- List the seven components of a strong problem statement.
- Differentiate a research objective from a research activity.
- Rewrite “to know why mothers deliver at home” as a measurable objective.
- Create an alignment matrix for one clinical research problem.
