"Updated to reflect changes that have occurred in health care and human service research since the first edition, Introduction to Research: Understanding and Applying Multiple Strategies, 2nd edition, recognizes and values multiple research strategies. It proposes that naturalistic and experimental-type research strategies have equal value and contribute in complementary and distinct ways to a science of practice. Knowledge of these different research traditions presents new opportunities for addressing the complex research questions that are emerging as a consequence of today's constantly changing health care and human service environments."--Jacket.
