Conducting Health Research: Principles, Process, and Methods presents an integrated and practical introduction to the principles and strategies for planning, implementing, reporting, and assessing health sciences research. Comprehensive in its breadth and depth, with an accessible writing style, this text prepares students in public health and related fields to be adept researchers and consumers of health research. Through real-world examples and step-by-step guidance, Frederick J. Kviz provides students with the skills they need to: identify and evaluate research strengths and limitations as practitioners; to actually perform the various core aspects of research; and to choose among alternative methods when making decisions about health practice, policy, and future research needs.

Overview
Research is conducted for many purposes, such as
- describing one or more populations at a particular point in time,
- exploring relationships among variables,
- identifying factors that account for differences across populations,
- monitoring stability/change within and across populations over time, and
- assessing causal relationships to evaluate the impact of interventions.
Moreover, factors such as the types of research participants, timing, conditions, key variables, and resources vary widely across studies. Typically, it is not adequate simply to plan a study by choosing from a menu ...
