Triangulation The application and combination of several research methodologies (e.g., focus groups, interviews, participant observation, and content analysis of documents) to study a phenomenon. By combining multiple observers, theories, methods of data collection, and empirical approaches, researchers can address intrinsic biases that emerge from a single method and a single-observer study. Triangulation is often used to establish the credibility of qualitative analyses, in contrast to the reliability and validity of quantitative analyses.

Unhealthfulness The quality of promoting poor health.
