Research Problem/Question
Identification of Problem Area, Research Problem, and Research Question
1. Identification of Problem Area
The problem area in research refers to a broad field of study that requires investigation. It is usually derived from real-world issues, literature gaps, professional experience, or social needs. Identifying the problem area is the first step in conducting research, ensuring that the study is relevant, significant, and feasible.
Steps in Identifying a Problem Area:
- Observation and Experience: Real-world challenges in healthcare, education, or industry.
- Literature Review: Identifying gaps or contradictions in existing studies.
- Expert Opinions: Consulting professionals and scholars in the field.
- Trends and Policies: Examining national/international reports, policies, and statistics.
- Feasibility Analysis: Considering resources, time, and ethical constraints.
2. Research Problem
A research problem is a specific issue, contradiction, or knowledge gap within the identified problem area that requires investigation. It provides direction for the research and helps in formulating a research question.
Characteristics of a Good Research Problem:
- Specific and clear (well-defined scope)
- Significant and relevant (addresses a real issue)
- Feasible (can be studied within available resources)
- Ethical (does not harm participants)
- Researchable (measurable and analyzable)
Examples of Research Problems:
- “What are the barriers to effective hand hygiene compliance among nurses in ICU?”
- “How does maternal education impact child vaccination rates in rural areas?”
- “What are the effects of shift work on nurses’ mental health and patient care quality?”
3. Research Question
A research question is a precise, focused query that guides the study. It is formulated based on the research problem and determines the study’s objective.
Types of Research Questions:
- Descriptive Questions (Explore characteristics of a phenomenon)
- Example: What are the common challenges faced by nursing students in clinical training?
- Comparative Questions (Compare two or more groups)
- Example: How does online learning compare to traditional classroom learning in nursing education?
- Causal Questions (Determine cause-effect relationships)
- Example: What is the effect of nurse-to-patient ratio on patient outcomes in critical care units?
Frameworks for Writing Research Questions:
- PICO (Population, Intervention, Comparison, Outcome) – For clinical research
- FINER (Feasible, Interesting, Novel, Ethical, Relevant) – Ensures good research questions
The process of identifying a problem area, defining a research problem, and formulating a research question is crucial in research methodology. A well-defined problem and question guide the study towards meaningful and impactful conclusions.
Problem Statement in Research
A Problem Statement is a clear, concise description of an issue that needs to be addressed in a research study. It establishes the need for the study, provides context, and justifies why the research is important.
Key Components of a Problem Statement:
- Background Information: Provides context about the issue.
- Existing Gap or Challenge: Highlights the gap in knowledge or practice.
- Significance of the Problem: Explains why the problem needs to be addressed.
- Consequences of Not Addressing the Problem: Discusses the potential risks if the problem remains unsolved.
- Scope and Focus: Narrows down the problem to a researchable aspect.
- Objectives of the Study: Specifies what the research aims to achieve.
Format of a Problem Statement
A well-written problem statement follows this structure:
- Introduction to the Problem – Briefly describe the broader issue.
- Current State of Knowledge – Mention what is already known.
- Gap in Literature or Practice – Identify what is missing or needs improvement.
- Significance of the Study – Explain the impact of solving the problem.
- Purpose of the Study – State what the study will achieve.
Example of a Problem Statement:
Example 1: Nursing Research
Title: Effect of Nurse-Patient Ratio on Quality of Patient Care in Intensive Care Units (ICUs)
Problem Statement:
“Nurse staffing levels play a critical role in ensuring high-quality patient care. Studies have shown that inadequate nurse-to-patient ratios lead to increased patient morbidity and mortality. Despite global nursing standards recommending a specific nurse-patient ratio, many hospitals fail to maintain these levels due to workforce shortages and financial constraints. This study aims to examine the impact of nurse-patient ratios on patient outcomes in ICUs, identifying the optimal staffing levels necessary for improved care and reduced complications.”
Example 2: Public Health Research
Title: Barriers to Childhood Immunization in Rural Areas
Problem Statement:
“Despite widespread vaccination programs, childhood immunization rates remain low in many rural areas. Factors such as lack of awareness, cultural beliefs, and healthcare accessibility contribute to vaccine hesitancy among parents. Existing literature highlights these challenges but lacks a comprehensive understanding of the role of community engagement in improving immunization rates. This study seeks to explore the key barriers and propose interventions to enhance immunization coverage in rural communities.
A problem statement is the foundation of any research study. It helps in defining the research focus, justifying the need for the study, and guiding the development of research questions and objectives.
Criteria of a Good Research Problem
A good research problem is the foundation of a successful study. It should be clear, relevant, researchable, and contribute to existing knowledge. Below are the key criteria that define a well-structured research problem:
1. Clarity and Specificity
- The problem should be well-defined and unambiguous.
- Avoid vague or overly broad topics.
- Example (Good): What are the effects of nurse-patient ratios on patient safety in ICU?
- Example (Poor): How does healthcare affect people? (Too broad)
2. Researchable and Feasible
- The problem should be empirically testable using research methods.
- Sufficient data, resources, and time should be available.
- It should not be based on speculation or unmeasurable concepts.
- Example: A study on the impact of maternal nutrition on newborn birth weight is researchable, while a study on the existence of life after death is not.
3. Novelty and Contribution to Knowledge
- The problem should address a gap in existing literature or bring new insights.
- It should contribute to academic, scientific, or professional fields.
- Example: If previous studies focused on urban hospitals, a study on rural healthcare challenges adds new knowledge.
4. Significance and Practical Relevance
- The research should have real-world applications.
- It should address social, clinical, or professional issues.
- Example: How does telemedicine improve healthcare access in remote areas?
→ This is relevant to improving healthcare systems.
5. Ethical Considerations
- The study should follow ethical principles (e.g., confidentiality, informed consent, non-harmful interventions).
- Example: A study on the psychological impact of child abuse survivors must ensure ethical handling of sensitive data.
6. Logical and Conceptual Basis
- The problem should be grounded in theoretical frameworks and supported by literature.
- Example: A study on nurse burnout should reference models like Maslach’s Burnout Inventory.
7. Availability of Data
- Reliable data sources should be available (e.g., hospital records, surveys, interviews).
- The study should not depend on extremely rare or highly restricted data.
8. Scope and Manageability

2. Alternative Hypothesis (H₁ or Hₐ)
- States that there is a significant relationship between variables.
- Example: A lower nurse-patient ratio significantly improves ICU patient care quality.
3. Directional Hypothesis
- Specifies the expected direction of the relationship.
- Example: Increasing nurse staffing levels will lead to improved patient outcomes in ICUs.
4. Non-Directional Hypothesis
- Predicts a relationship but does not specify the direction.
- Example: There is a relationship between nurse staffing levels and patient outcomes in ICUs.
5. Statistical Hypothesis
- Used in quantitative research and tested using statistical methods.
