Qualitative Research Methods Indian Medical PG Practice Questions and MCQs
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
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.
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)
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.
Question 3: Leading questions are permitted only in-
- A. Re-examination
- B. Examination in chief
- C. Dying declaration
- D. Cross examination (Correct Answer)
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.
Question 4: An example of a two-way discussion is:
- A. A seminar
- B. Group discussion (Correct Answer)
- C. Role playing
- D. Symposium
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.
Question 5: 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
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.
Question 6: 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)
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.
Question 7: 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)
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.
Question 8: 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
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.
Question 9: A surgical department of a premier medical college conducted a study on rates of post-operative wound infection. The results of the study were negative for the proposed hypothesis. What should the department do with the results?
- A. Label them as worthless
- B. Redo the study with a new hypothesis
- C. Report the negative results (Correct Answer)
- D. Redesign the study and increase the sample size
Explanation: **Report the negative results** - All research findings, whether positive or negative, contribute to the body of scientific knowledge and should be **ethically reported** to prevent publication bias. - Reporting negative results helps other researchers avoid duplicating efforts and can inform future study designs, potentially leading to a better understanding of the topic. *Label them as worthless* - Labeling negative results as "worthless" contradicts the principles of **scientific integrity** and promotes publication bias, where only positive findings are disseminated. - Even negative findings can provide crucial insights, indicating that a particular intervention or hypothesis is not supported, thus saving time and resources for future research. *Redo the study with a new hypothesis* - While forming new hypotheses may be necessary in some cases, redoing the study with a completely new hypothesis without reporting the initial negative results would be **unethical** and contribute to the problem of **publication bias**. - **New hypotheses** should ideally be formulated based on a comprehensive understanding of existing research, including negative findings. *Redesign the study and increase the sample size* - While redesigning the study and increasing sample size might be appropriate after the initial results have been reported and analyzed, the **immediate and ethical step** is to report the existing negative findings. - A larger sample size alone does not guarantee positive results; careful reevaluation of the methods and hypothesis is needed if the initial study was well-conducted.
Question 10: Which sociological theory posits that prioritizing profit over health is a cause of disease?
- A. Marxist theory (Correct Answer)
- B. Feminist theory
- C. Parsonian theory
- D. Foucauldian theory
Explanation: ### Explanation **Correct Answer: A. Marxist theory** **Why it is correct:** The **Marxist theory** of health (Conflict Theory) views medicine and disease through the lens of social class and economic power. It posits that in a capitalist society, the **pursuit of profit** often takes precedence over public health. According to this theory, the capitalist system causes disease directly (through poor working conditions, environmental pollution, and poverty) and indirectly (by commodifying healthcare, where medical care is a product for sale rather than a social right). It argues that the medical profession serves the interests of the ruling class by focusing on individual clinical treatments rather than addressing the socio-economic "root causes" of illness. **Why the other options are incorrect:** * **B. Feminist theory:** Focuses on gender inequality and how the patriarchal structure of society affects women’s health, reproductive rights, and their experiences within the healthcare system. * **C. Parsonian theory (Functionalism):** Introduced by Talcott Parsons, it focuses on the **"Sick Role."** It views illness as a form of social deviance that disturbs the stability of society; the "sick role" provides a mechanism for the individual to be excused from social duties while being obligated to seek professional help to get well. * **D. Foucauldian theory:** Michel Foucault focused on **"Medical Gaze"** and **"Biopower."** It explores how medical knowledge is used as a form of social control and surveillance to regulate bodies and populations. **High-Yield Clinical Pearls for NEET-PG:** * **Marxist Theory:** Keywords: *Capitalism, Profit over Health, Social Class, Political Economy.* * **Talcott Parsons:** Keywords: *Sick Role, Rights and Obligations of the patient.* * **Social Determinants of Health:** While Marxist theory is a sociological critique, it aligns with the concept that health is determined more by socio-economic status than by biological factors alone. * **Medicalization:** The process by which non-medical problems become defined and treated as medical issues (often linked to both Marxist and Foucauldian critiques).
