UGC NET Questions (Paper – 1)

A systematic review follows a rigorous protocol that includes clearly formulated research questions, predefined inclusion and exclusion criteria, systematic search strategies and explicit methods for assessing study quality. It aims to locate and synthesise all relevant empirical evidence to answer a particular question, minimising bias. Often, systematic reviews may be accompanied by meta-analyses. Because the stem emphasises explicit criteria for identifying, appraising and synthesising evidence, systematic review is the correct term.

Option A:
Narrative reviews are more informal and may summarise research selectively without following a transparent, replicable protocol. They rely heavily on the reviewer’s judgment and are more vulnerable to bias. While useful for broad overviews, they do not match the explicit, pre-specified procedures described in the stem.

Option B:
Systematic reviews provide a comprehensive and reproducible approach to summarising evidence, supporting evidence-based decision-making in many fields such as education and health. Their stepwise procedures and documented search strategies align precisely with the stem’s description, confirming systematic review as the appropriate completion.

Option C:
Historical reviews focus on the chronological development of ideas, theories or practices over time. They may not employ formal inclusion criteria or comprehensive search strategies targeted at answering a specific empirical question. Hence, historical review is not the best answer here.

Option D:
Critical reviews emphasise evaluating and critiquing existing literature, sometimes proposing new conceptual frameworks, but they may not involve exhaustive, protocol-driven searches and standardised quality assessment of studies. Therefore, critical review is not the correct completion for a process defined by explicit, pre-specified criteria for identifying and synthesising all relevant evidence.
