What kinds of research evidence are useful?

There are many different kinds of research available. Etiological research examines what causes health problems. Health determinants can be studied either qualitatively or quantitatively to understand the complex relationships among determinants of the problem. Laboratory studies can show what biological or environmental factors are at play. Organizational and policy studies can reveal external influences on the issue. It’s usually best to use reviews, or syntheses of research, rather than single studies. They are more likely to show overall factors that affect situations. Integrative reviews go further because they assemble findings from both qualitative and quantitative studies. An integrative review includes (1) problem formulation, (2) collecting data or doing a literature search, (3) evaluating data, (4) analyzing it, and (5) interpreting and presenting its results. (Russell, 2005). Integrative reviews can be used to evaluate the strength of evidence, to identify research gaps and issues and to link related areas of work.
