delimitations

Delimitations are the intentional choices that define the scope of a study by establishing boundaries around what will be included and excluded. They are distinct from limitations, which arise from practical constraints or unforeseen problems after the study begins.

Typical delimitations involve the characteristics of the study population (for example, selecting university students rather than a general population), geographic location (a city or region), time frame (a single semester or year), and the variables or constructs examined (focusing on specific outcomes or excluding others). Delimitations also cover methodological choices such as using a particular research design, data sources, or measurement instruments, as well as theoretical scope or framing.

The purpose of delimitations is to clarify feasibility, maintain coherence, and enhance the interpretability of results. They influence the generalizability or transferability of findings, and readers should consider them when applying conclusions to other contexts.

Researchers typically document delimitations in the methods section or a dedicated limitations and delimitations section, stating what was deliberately excluded and why. They may also note how these choices might bias results or limit applicability, and suggest avenues for future research to broaden scope.
