A research problem is... Correct Answer: A gap in knowledge
A need in patient care
Something wrong with current care
Examples of statements describing a problem Correct Answer: Little is known about...
Findings from previous studies are conflicting
Few studies have been done concerning...
Women and minority populations have not been studied in
Significance of a problem Correct Answer: Many people are affected
It is costing a lot of money
It causes disease, discomfort or death
It lowers quality of life
The research problem and significance statement are found in what part of a study? Correct Answer:
Literature review
What is the problem in this literature;
The prevalence of overweight among adolescents tripled in the last 20 years, and these youth have a
70% chance of becoming obese adults. Although adolescents can identify healthy food, they often lack
the ability or motivation to apply this knowledge in food selection. Few interventions have focused on
motivating youth to make healthy choices. What is the significant statement? Correct Answer: Few
interventions have focused on motivating youth

70% chance of becoming obese adults
Is this statement a problem or a significance statement;
500,000 to 1 million people have leg ulcers at any one time. 60-70% of the patients have recurrent
ulcers. The average cost to heal a venous ulcer is $1,950 Correct Answer: significance statement
Is this statement a problem or a significance statement;
Impaired tissue perfusion is related to slow wound healing. Partial pressure TC oxygen measurements
predict wound healing in persons with impaired perfusion. Few data are available regarding the effect of
this intervention on tissue oxygenation and wound healing in persons with venous ulcers Correct
Answer: a problem statement
What must you consider for a study to be feasible? Correct Answer: Time commitment
Financial cost
Researcher expertise
Availability of subjects
Availability of facilities
Cooperation of others
, What are research objectives? Correct Answer: Declarative statements; clear & concise; present tense;
focused on the identification & description of variables
What Are Variables? Correct Answer: Qualities, properties, or characteristics of persons, things, or
situations that change or vary, and are measured in research.
Independent Variable Correct Answer: Treatment or experimental variable
Manipulated by researcher
Causes change in
something else
Dependent Variable Correct Answer: Outcome variable
Response or Effect
Variable measured in both treatment & control or comparison groups
Extraneous Variables Correct Answer: Recognized or unrecognized
Controlled or uncontrolled
Confounding variables
Environmental variables
Conceptual Definition Correct Answer: The abstract meaning of a variable that usually is based on
theory.
Operational Definition Correct Answer: A way of defining a variable that makes it measurable or
manipulatable in the real world
What type of definition is this (operationalizing a variable) Coping behaviors are actions directed toward
managing internal and environmental demands that tax or exceed a person's resources (Lazarus &
Folkman, 1984). Correct Answer: Conceptual Definition of Coping Behavior
What type of definition is this (operationalizing a variable) Coping behaviors were measured with the
Ways of Coping Checklist (WCC), a 68-item scale that contains eight subscales: one problem-focused
scale, six emotion-focused scales, and one problem- and emotion-focused scale (O'Brien, 1993). Correct
Answer: Operational Definition of Coping Behavior
Research Questions Correct Answer: Interrogative statements that focus on what variables or concepts
are to be described & what relationships might exist among them.
What are hypotheses? Correct Answer: Formal statement of the expected relationships among
variables.
Demographic Variables Correct Answer: Age
Gender
Ethnicity or race
Education
Income
Diagnoses
