ANS: A
Outcomes research emerged as an important methodology for documenting the effectiveness of
health care services in the 1980s and 1990s. This type of research evolved from the quality
assessment and quality assurance functions that originated with the professional standards review
organizations (PSROs) in 1972. During the 1980s, William Roper, the director of the Health
Care Finance Administration (HCFA), promoted outcomes research for determining the quality
and cost-effectiveness of patient care. Intervention research investigates the effectiveness of a
nursing intervention in achieving the desired outcome or outcomes in a natural setting. Through
the use of ethnographic research, different cultures are described, compared, and contrasted to
add to our understanding of the impact of culture on human behavior and health. Experimental
studies have three main characteristics: (1) a controlled manipulation of at least one treatment
variable (independent variable), (2) administration of the treatment to some of the subjects in the
study (experimental group) and not to others (control group), and (3) random selection of
subjects or random assignment of subjects to groups, or both. Experimental studies usually are
conducted in highly controlled settings, such as laboratories or research units in clinical agencies.
