Three main types of quantitative research methods used by
interventions in the Portal.

Analytic observational studies (III) include cohort studies,
and case control studies.

Quasi-experimental designs (II) include controlled studies
without random assignment, but with control groups,
comparison groups, or counter-balanced designs.

Experimental design (I) refers to controlled studies with
random assignment of participants in experimental
conditions; for example, randomised controlled trials (RCTs).

The Portal ranks qualitative research studies into three categories:

A single case study (III). Single case studies are designed to
provide insight into a research question that has not been
previously explored in much detail.

Descriptive studies (II). This category includes studies that
describe several viewpoints about a particular topic.

Generalizable conceptual studies (I). This category includes
studies that proceed from a theoretical framework that has been
developed from earlier research.
