Designing a Study You Can Defend
Recruitment difficulties do not always justify extending a study's recruitment period. When low enrollment reflects inaccessible populations, systematic selection, or an unattainable sample size, researchers may need to reconsider the design itself. Learn how to distinguish temporary recruitment delays from structural feasibility problems and make defensible changes without compromising research integrity.

Sensitivity analyses help researchers examine whether findings depend on uncertain assumptions or analytical choices. Learn why important sensitivity analyses should be planned during research design, how to select meaningful alternatives, and how to interpret results that change across assumptions.

An analysis plan can reveal that a proposed research design cannot support its intended conclusions. Learn how analytical planning exposes missing measurements, inadequate comparisons, insufficient independent units, and identification problems before data collection makes them difficult to correct.

Testing a research design before the main study can reveal problems with recruitment, procedures, instruments, data management, and analysis while there is still time to fix them. The appropriate form and extent of testing depend on what is uncertain and how consequential failure would be.

Not every research decision requires the same degree of advance specification. Learn which design, measurement, sampling, and analysis choices are most consequential for confirmatory inference and how to document them clearly before examining results.

Early peer review through Registered Reports allows researchers to address methodological weaknesses before conducting the principal study. Learn which design problems reviewers can identify, when prospective feedback is most valuable, and why early review does not automatically guarantee better research.

An ideal research design may cost more than the resources available. Learn how to reduce research expenses, preserve methodological integrity, and decide when narrowing or postponing a study is more defensible than compromising its design.

Designing a Study You Can Defend
A research design may be scientifically appropriate but impossible to complete within the available time. Learn how to identify critical dependencies, distinguish essential observation periods from avoidable delays, and adapt your study without overstating what shorter-term evidence can establish.

Designing a Study You Can Defend
A research design may require statistical, technical, clinical, or methodological expertise that your team does not possess. Learn how to identify essential competencies, obtain appropriate support, and determine when adapting the design is more defensible than proceeding without qualified expertise.

Your preferred research design may depend on equipment that is unavailable, unaffordable, or inaccessible. Learn how to evaluate alternative instruments, collaborate with equipped facilities, protect measurement validity, and determine when equipment limitations require a different research question.

Designing a Study You Can Defend
A multisite research design may exceed your capacity to coordinate institutions, facilities, or field locations. Learn how to prioritize sites, assess the consequences of reducing their number, and determine when a focused study is more defensible than an inadequately managed multisite project.

Designing a Study You Can Defend
A research design may require more participants, rarer cases, or greater population diversity than you can realistically recruit. Learn how to improve recruitment, reassess sample adequacy, and determine when a smaller sample or revised research question remains methodologically defensible.

Designing a Study You Can Defend
When your research design becomes infeasible, simplifying the methods, narrowing the question, and postponing the study are not interchangeable solutions. Learn how to distinguish these decisions and choose the option that preserves the scientific purpose and integrity of your research.

Designing a Study You Can Defend
A study may be affordable, manageable, and possible to complete yet still lack the methodological strength needed to answer its research question. Learn how to recognize when limitations become fundamental weaknesses and determine whether to revise, narrow, or discontinue the proposed study.

An appropriate thesis or dissertation design must be scientifically defensible and realistically completable within academic deadlines. Learn how to account for approvals, recruitment, data collection, analysis, and revision while avoiding designs that depend on uncertain or uncontrollable milestones.

Longitudinal research can provide valuable evidence about change over time, but its observation periods and follow-up requirements may conflict with graduation deadlines. Learn when students should retain, adapt, or avoid longitudinal designs and how existing data or shorter observation windows may provide defensible alternatives.

A complex research design may offer stronger causal inference, broader coverage, or more detailed evidence, but those advantages depend on proper implementation. Learn when students should choose a simpler design, when methodological complexity is essential, and how to avoid sacrificing scientific adequacy for convenience.

Designing a Study You Can Defend
A dissertation may investigate a complex problem through several connected studies rather than one design attempting to answer everything. Learn when linked designs are justified, how to establish a coherent relationship among studies, and how to manage the additional dependencies, integration requirements, and completion risks.

Designing a Study You Can Defend
Some thesis and dissertation activities depend on approvals, participants, equipment, collaborators, or earlier study components that students cannot fully control. Learn how to identify the most consequential dependencies, distinguish ordinary delays from critical failure points, and design a research plan that remains scientifically defensible and realistically completable.

Designing a Study You Can Defend
Limited laboratories, unreliable connectivity, restricted software access, and inadequate technical support can make conventional research procedures difficult to implement. Learn how to distinguish essential infrastructure from replaceable resources, evaluate alternative methods, and develop a scientifically defensible study suited to local conditions.

Designing a Study You Can Defend
Limited funding, equipment, expertise, infrastructure, or participant access may make an ideal research design impossible to implement. Yet choosing a different design does not automatically make a study inferior. Learn how to distinguish scientifically defensible adaptations from methodological compromises and determine when an alternative design can produce equally valuable, though sometimes different, evidence.

Designing a Study You Can Defend
Research conducted with locally available resources may capture conditions that highly controlled studies overlook. Yet contextual realism does not automatically establish validity or generalizability. Learn when local adaptation strengthens real-world relevance, how to distinguish implementation conditions from methodological compromises, and how to preserve scientific rigor.

Resource limitations may require changes to sampling, measurement, follow-up, or analytical procedures. Some adaptations preserve the research question, while others fundamentally change what the study can establish. Learn how to identify unacceptable methodological compromises, evaluate alternative designs, and revise research objectives when essential evidence can no longer be collected.
