Qualitative Research Methods Indian Medical PG Practice Questions and MCQs
Practice Indian Medical PG questions for Qualitative Research Methods. These multiple choice questions (MCQs) cover important concepts and help you prepare for your exams.
Qualitative Research Methods Indian Medical PG Question 1: Which of the following is a type of observational study that analyzes population-level data?
- A. Ecological study (Correct Answer)
- B. Case-control study
- C. Randomized controlled trial
- D. Longitudinal study
Qualitative Research Methods Explanation: ***Ecological study***
- This type of study examines the relationship between an exposure and an outcome at the **population level** rather than the individual level.
- It often uses aggregated data, such as incidence rates of disease in different geographic areas, to identify associations.
*Case-control study*
- This is an **individual-level observational study** that compares individuals with a disease (cases) to individuals without the disease (controls) and looks back retrospectively at their exposures.
- It is used to investigate potential risk factors for a disease but does not analyze population-level data directly.
*Randomized controlled trial*
- This is an **experimental study design** where participants are randomly assigned to an intervention group or a control group.
- It is considered the gold standard for establishing causality but does not analyze observational population-level data.
*Longitudinal study*
- This is an **individual-level observational study** that follows the same group of individuals over a period of time, collecting data at multiple points.
- While it observes changes over time, it typically focuses on individual-level trends and outcomes, not aggregated population data.
Qualitative Research Methods Indian Medical PG Question 2: Which of the following is not a criterion suggesting causality in non communicable diseases?
- A. Specificity of association
- B. Dose response relationship
- C. Strength of association
- D. Lack of temporal association (Correct Answer)
Qualitative Research Methods Explanation: ***Lack of temporal association***
- For an exposure to cause a non-communicable disease, the exposure must precede the disease onset; therefore, a **lack of temporal association** explicitly argues *against* causality.
- This criterion is a fundamental principle of causality, as the **cause must occur before the effect**.
*Specificity of association*
- This criterion suggests that a single exposure should lead to a single disease. However, in non-communicable diseases, a single risk factor may contribute to multiple diseases (e.g., smoking and lung cancer, heart disease, stroke), and a single disease can have **multiple causes**.
- While it was important in the original Bradford Hill criteria, its relevance is diminished in modern epidemiology due to the **multifactorial nature of chronic diseases**.
*Dose response relationship*
- This criterion implies that as the **amount or duration of exposure increases**, the **risk or severity of the disease also increases**.
- This is a strong indicator of causality because it suggests a biological gradient.
*Strength of association*
- A strong association, often measured by a **high relative risk or odds ratio**, increases the likelihood of a causal relationship.
- A weak association, while not ruling out causality, makes it less likely to be directly causal and more likely to be influenced by other factors or confounding variables.
Qualitative Research Methods Indian Medical PG Question 3: Leading questions are permitted only in-
- A. Re-examination
- B. Examination in chief
- C. Dying declaration
- D. Cross examination (Correct Answer)
Qualitative Research Methods Explanation: ***Cross examination***
- **Leading questions** are questions that suggest the answer the examiner wishes to elicit. They are generally permitted in **cross-examination** to challenge the witness's testimony and probe for inconsistencies.
- The purpose of cross-examination is to test the **veracity** and **accuracy** of the evidence given by the witness during direct examination.
*Re-examination*
- **Re-examination** follows cross-examination and is conducted by the party who called the witness, but it is limited to explaining or clarifying matters raised during cross-examination.
- **Leading questions** are generally not allowed during re-examination, as its purpose is to rehabilitate the witness, not introduce new evidence or suggest answers.
*Examination in chief*
- **Examination in chief** (or direct examination) is when a lawyer questions their own witness to elicit factual information relevant to their case.
- **Leading questions** are typically prohibited during examination in chief to ensure that the testimony is the witness's own and not influenced by the lawyer.
*Dying declaration*
- A **dying declaration** is a statement made by a person who is conscious and believes death is imminent, regarding the cause and circumstances of their impending death.
- It is an exception to the **hearsay rule** and is usually recorded as a statement, not as a process involving direct questioning where leading questions would be applied in a court setting.
Qualitative Research Methods Indian Medical PG Question 4: The study unit of an ecological study is
- A. Case
- B. Individual Patient
- C. Population (Correct Answer)
- D. Family
Qualitative Research Methods Explanation: ***Population***
- An **ecological study** examines health phenomena at a **population or group level**, not at the individual level.
- The study unit is the **population** (also referred to as community or group), where aggregate data such as disease rates, mortality statistics, or average exposures are analyzed.
- This design investigates correlations between exposure and outcome across different populations or within the same population over time.
- Examples include comparing cancer rates between countries with different dietary patterns, or analyzing disease trends over time in a specific region.
*Individual Patient*
- An **individual patient** is the unit of study in **clinical trials**, cohort studies at individual level, or case reports.
- Ecological studies specifically use aggregate data at the population level, not individual-level data.
- The focus is on group characteristics rather than individual characteristics.
*Case*
- A **case** refers to an individual with a specific disease or condition.
- This is the primary unit in **case-control studies** or **case reports** where individual patients are identified and studied.
- Ecological studies do not collect data on individual cases but rather use population-level aggregated data.
*Family*
- A **family** can be a unit of study in family-based studies or genetic epidemiology research.
- However, ecological studies operate at a broader population level, not at the family unit level.
- Family studies focus on clustering of disease within families, which is different from ecological study design.
Qualitative Research Methods Indian Medical PG Question 5: An example of a two-way discussion is:
- A. A seminar
- B. Group discussion (Correct Answer)
- C. Role playing
- D. Symposium
Qualitative Research Methods Explanation: ***Group discussion***
- A **group discussion** involves multiple participants actively exchanging ideas and perspectives, representing a classic example of **two-way communication**.
- Participants engage in speaking and listening, providing **feedback** and allowing for a dynamic exchange of thoughts.
*A seminar*
- A **seminar** is typically a more formal presentation where an expert delivers information to an audience with limited opportunity for extensive **two-way discussion**.
- While questions may be asked, the primary flow of information is often **one-way**, from presenter to attendees.
*Role playing*
- **Role-playing** is an instructional technique where individuals act out specific roles or scenarios, focusing on **experiential learning** rather than open discussion.
- While there is interaction between participants, the primary goal is often to practice skills or understand a perspective, not necessarily to have an unstructured **two-way debate** or idea exchange.
*Symposium*
- A **symposium** is a meeting or conference at which experts deliver papers on a particular subject, typically followed by a relatively brief **question-and-answer session**.
- The format is largely **one-way**, with experts presenting information and the audience primarily receiving it.
Qualitative Research Methods Indian Medical PG Question 6: All of the following are done to remove Confounding except:
- A. Randomization
- B. Random Selection
- C. Matching
- D. Blinding (Correct Answer)
Qualitative Research Methods Explanation: ***Blinding***
- **Blinding** is a technique used to minimize **bias** (e.g., observer bias, participant bias) by preventing study participants, researchers, or data analysts from knowing treatment assignments. It does **not address confounding variables**.
- Blinding ensures that knowledge of the intervention does not influence the outcomes or their assessment, thereby controlling **information bias** and **performance bias**.
*Randomization*
- **Randomization** is a key method in experimental studies to control for **confounding variables** by distributing them equally among study groups.
- It ensures that each participant has an **equal chance** of being assigned to any study group, thus minimizing systematic differences between groups at baseline.
*Random Selection*
- **Random selection** (or random sampling) is used primarily to create a sample that is **representative** of the larger population, thereby improving **external validity** and **generalizability**.
- While it reduces **selection bias**, random selection is **not a standard method for controlling confounding**. Some sources suggest it may help balance unknown confounders compared to convenience sampling, but it is not classified among the primary confounding control methods (randomization, restriction, matching, stratification, multivariable analysis).
- In this question context, if we consider standard epidemiological methods, random selection's role in confounding control is indirect at best.
*Matching*
- **Matching** is a technique used in observational studies to control for known **confounding variables** by selecting controls who are similar to cases with respect to these confounders.
- For example, if age and sex are confounders, controls are matched to cases based on these characteristics to ensure comparability and reduce confounding.
Qualitative Research Methods Indian Medical PG Question 7: What is the primary purpose of interventional studies in clinical research?
- A. Confirming Hypotheses
- B. Testing Hypotheses (Correct Answer)
- C. Manipulating Hypotheses
- D. Formulating Hypotheses
Qualitative Research Methods Explanation: ***Testing Hypotheses***
- Interventional studies, such as **randomized controlled trials**, are specifically designed to **test cause-and-effect relationships** by actively intervening.
- They aim to determine if a specific intervention (e.g., a drug, a therapy) produces a hypothesized outcome.
*Confirming Hypotheses*
- While interventional studies can confirm hypotheses, their primary role is not just confirmation but the initial **rigorous testing** of a hypothesis under controlled conditions.
- Confirmation often implies that previous evidence already strongly supports the hypothesis.
*Manipulating Hypotheses*
- Hypotheses themselves are not "manipulated"; rather, the **variables** within the study design (e.g., treatment groups, dosages) are manipulated to test the hypothesis.
- This option incorrectly applies the concept of manipulation to the hypothesis.
*Formulating Hypotheses*
- Hypothesis formulation usually occurs during the **observational research phase** or through literature review, *before* interventional studies are designed.
- Observational studies or descriptive research are more typically used for generating new hypotheses.
Qualitative Research Methods Indian Medical PG Question 8: Which of the following is not a method of random sampling?
- A. Cluster sampling
- B. Stratified sampling
- C. Simple random
- D. Quota sampling (Correct Answer)
Qualitative Research Methods Explanation: ***Quota sampling***
- **Quota sampling** is a non-probability sampling method where researchers select a sample based on pre-defined characteristics to match the population's proportions.
- It does not involve random selection at any stage, making it a non-random sampling technique.
*Cluster sampling*
- **Cluster sampling** is a probability (random) sampling technique where the population is divided into clusters, and then a random sample of these clusters is selected.
- All units within the selected clusters are then included in the sample, or a random sample is taken from within the selected clusters.
*Stratified sampling*
- **Stratified sampling** is a probability (random) sampling method that involves dividing the population into homogeneous subgroups (strata) and then taking a random sample from each stratum.
- This method ensures representation from all important subgroups within the population.
*Simple random*
- **Simple random sampling** is a basic probability (random) sampling technique where every member of the population has an equal chance of being selected for the sample.
- This method is considered the most fundamental type of random sampling.
Qualitative Research Methods Indian Medical PG Question 9: This is a map of an urban slum in New Delhi. The medical officer of PHC notified the higher authorities on observing multiple cases of measles in 1-2 years age group. The authorities conducted a survey of vaccine coverage in the area in the manner shown below. Which sampling is depicted here?
- A. Simple random sampling
- B. Systematic random sampling
- C. Stratified random sampling
- D. Cluster sampling (Correct Answer)
Qualitative Research Methods Explanation: ***Cluster sampling***
- The image shows **groups (clusters)** of houses (red houses within red circles) being selected, and then all units within those selected groups are included in the sample.
- This method is typically used when the population is naturally divided into groups, such as geographical areas or blocks, making it **cost-effective** and practical, especially in large, dispersed populations like an urban slum.
*Simple random sampling*
- This method would involve **randomly selecting individual houses** from the entire slum without any pre-defined grouping, which is not depicted in the image.
- Each house would have an **equal chance of being selected**, and sampling would not be restricted to specific clusters.
*Systematic random sampling*
- Involves selecting houses at a **fixed interval** (e.g., every 5th house) from a sorted list or along a defined path after a random starting point.
- The image does not show a systematic selection process or an underlying order for sampling the houses.
*Stratified random sampling*
- This method involves **dividing the population into homogeneous subgroups** (strata) based on a characteristic (e.g., age, income level) and then drawing a random sample from each stratum.
- While the map shows 'sections', these are not necessarily strata based on a relevant characteristic, and the sampling is not shown to be proportional or disproportional across these sections.
Qualitative Research Methods Indian Medical PG Question 10: Consider the following management methods/techniques :
1. System analysis
2. Organizational design
3. Personnel management
4. Information systems
Which of the above methods/techniques are based on behavioural sciences?
- A. 1, 2 and 3 (Correct Answer)
- B. 1, 2 and 4
- C. 2, 3 and 4
- D. 1, 3 and 4
Qualitative Research Methods Explanation: ***1, 2 and 3***
- **System analysis** in management context involves understanding human behavior within organizational systems, analyzing workflows, and interpersonal dynamics to optimize processes and structures. When applied to organizational management, it incorporates behavioral principles.
- **Organizational design** is fundamentally rooted in behavioral sciences, focusing on structuring roles, relationships, and hierarchies to enhance human interaction, motivation, and performance based on principles from organizational psychology and sociology.
- **Personnel management** directly deals with human resource management, applying behavioral science principles including motivation theory, leadership styles, group dynamics, employee relations, and organizational behavior.
*1, 2 and 4*
- This option incorrectly includes **information systems**, which are primarily technology-focused and rooted in computer science and data management rather than behavioral sciences.
- While information systems may influence organizational behavior, their core methodologies are not based on behavioral science principles.
*2, 3 and 4*
- This option incorrectly includes **information systems** while excluding **system analysis**.
- Information systems are technology-based rather than behavioral science-based.
*1, 3 and 4*
- This option incorrectly includes **information systems**, which are technology-focused rather than behavioral science-based.
- It also excludes **organizational design**, which is a fundamental behavioral science application in management, focusing on how structure affects human behavior and organizational effectiveness.
