MULTIPLE CHOICE
1. Intervention research shifts the focus from causal connection to causal explanation. What
does this mean?
a. It allows correlational research determining connection to stand in the place of causal
explanation.
b. It provides theoretical explanations of why an independent variable produces an effect, rather
than merely reporting findings.
c. It may use studies that establish causal connection as impetus points, but it proceeds on to
descriptive research whenever possible, to explain.
d. It utilizes experimental research, whenever possible, to establish cause definitively.

Intervention research is a methodology that holds great promise as a more effective way of
testing interventions. It shifts the focus from causal connection to causal explanation. In
causal connection, the focus of a study is to provide evidence that the intervention contributes
to the outcome. In causal explanation, in addition to demonstrating that the intervention
causes the outcome, the researcher must provide scientific evidence to explain why the
intervention contributes to changes in outcomes and how it does so. Causal explanation is
theory based. Thus, research focused on causal explanation is guided by theory, and the
findings are expressed theoretically (see Chapter 7). Researchers employ a broad base of
methodologies, including qualitative studies, to examine the effectiveness of an intervention.
Qualitative approaches offer substantial value to the development, feasibility, and validation
of nursing interventions.

2. Why may intervention research involve the efforts of an entire project team?
a. A multidisciplinary team provides the grounding, objectivity, and world wisdom to judge
whether an intervention really has clinical merit.
b. Each member of the team carries out a separate research project at a different site, so that the
results can be multi-site and more readily generalizable.
c. Institutional review boards will not approve intervention projects unless they are backed by
an entire team, including representatives from both nursing and medicine.
d. It is rare for one person to be imaginative, clinically current, expert at marketing, skilled in
statistics, and adept at both quantitative and qualitative research.
ANS: D
Because of the nature of intervention research, one may need to gather a multidisciplinary
project team to facilitate distribution of the work and a broader generation of ideas. If both
quantitative and qualitative data will be gathered during the research project, the team should
include members experienced in various qualitative and quantitative data collection and
analysis approaches. Including a team member with marketing expertise will be beneficial,
because the final step of the project will be to market the intervention.
