Q

a nurse researcher is interested in the development of empathy in nursing students. Finding the lack of an appropriate instrument to use to study empathy in this population, the researcher has written a new instrument to gather data about the presence of empathy in nursing students.

what are the key questions the researcher needs to answer to confirm the instrument’s content validity?

A

The researcher needs to confirm how well the items on the instrument reflect the description of empathy in the literature, confirm the relevance of items on the instrument by content
experts’ evaluation, and examine potential subjects’ responses to the instrument’s items.

Q

a nurse researcher is interested in the development of empathy in nursing students. Finding the lack of an appropriate instrument to use to study empathy in this population, the researcher has written a new instrument to gather data about the presence of empathy in nursing students.

which type of procedure would be used to assess the stability of the new instrument

A

Stability is usually measured using test-retest reliability. It is concerned with the consistency
of repeated measures of the construct. Using this technique requires an assumption that the factor
to be measured (in this case, empathy) remains the same at the two testing times and that any
change in the value or score is a consequence of random error

Q

a nurse researcher is interested in the development of empathy in nursing students. Finding the lack of an appropriate instrument to use to study empathy in this population, the researcher has written a new instrument to gather data about the presence of empathy in nursing students.

What would a test-retest reliability value of 0.85 represent for the newly developed instrumen

A

A value of 0.85 is very solid test-retest reliability for the new scale, indicating that it is
consistently measuring empathy with repeat testing and recognizing that students’ level of empathy
varies somewhat over time

Q

a nurse researcher is interested in the development of empathy in nursing students. Finding the lack of an appropriate instrument to use to study empathy in this population, the researcher has written a new instrument to gather data about the presence of empathy in nursing students.

What information would the researcher share in a published report about the development of this
new instrument

A

The researcher would describe the theoretical consideration that went into the
development of the instrument and discuss the facts about the instrument, including what type
instrument it is, scaling, length, readability, scoring, and interpretation of results. Then the researcher
would summarily describe each assessment conducted to provide evidence of the instrument’s
validity and reliability. At the minimum in this scenario, this would include assessment of test-retest
reliability and homogeneity, computing the Cronbach’s alphas for each, and at least one measure of
convergence, using an available instrument measuring empathy or a similar concept.

critical appraisal should be a(n)
balanced appraisal of a study's strengths and weaknesses
26
3 steps of critically appraising a study
1. identifying the steps of the research process in studies 2. determining the study's strengths and weaknesses 3. evaluating the credibility and meaning of study findings -interpretation of findings -limitations -conclusions
27
critical appraising guidelines for each section of a research article apply the guidelines to be able to critique research articles
1. writing quality 2. title 3. authors 4. abstract 5. research problem - why is this an issue 6. purpose - does it clarify what the study is about 7. literature review 8. framework or theoretical perspective 9. research objectives, questions, or hypothesis 10. variables -demographics, independent, dependent, research variables or concepts, conceptual and operational definitions 11. research design 12. sample 13. setting 14. measurement -strategies used, scales and questionnaires, observation, interviews, physiological measures, adequacy of measures, validity and reliability 15. data collection -how, who, is it ethical ?? 16. data analysis -procedures, statistical significance??
28
what is the purpose of critically appraising studies in nursing?
29
why is it important to perform an intellectual critical appraisal of a study?
-strengths -weaknesses -credibility -meaning -significance for practice
30
research utilization involves a. communication of research findings b. observing outcomes from changing practice c. use of knowledge in practice d. all of the above
d. all of the above
31
strongest evidence
-meta-analysis, systematic review -integrative reviews -experimental studies
32
weakest evidence
-descriptive surveys -qualitative studies - correlational studies - quasi-experimental studies
33
sampling in research my be defined as
selection of a subset of a population to represent the whole population
34
2 ways to define sampling criteria
homogenous sample: as similar as possible so as to control for extraneous variables heterogeneous sample: represents a broad range of values -used when a narrow focus is not desirable
35
refusal rate
percentage of subjects who declined to participate in the study -80 subjects approached and 4 refused 4 / 80 = 0.05 = 5% 10% OR LESS
36
acceptance rate
percentage of subjects who consented to be in the study we want it to be > 90% !!!!! -80 subjects approached and 76 accepted 76/80 = 0.95 = 95%
37
sample attrition
withdrawal or loss of subjects from a study -attrition rate = number of subjects withdrawing / the number of study subjects x 100
38
sample retention
number of subjects who remain in and complete a study
39
types of probability sampling
simple random sampling - usually generated stratified random sampling - good to use when you want a good distribution of ethnicity or gender cluster sampling - like from zip codes systematic sampling - every 3rd person or every ___ person out of a list
40
ePersonal health Record
a private, secure application through which a individual may access, manage, and share his or her health information
41
Population
the entire set of individuals or elements that are the focus of the research.
42
Accessible population
is the portion of the target population to which the researcher has reasonable access.
43
Inclusion Criteria
the characteristics that the subjects must possess to be part of the target population Examples: the criteria here must include a definition of “students” and “students who are fulfilling parenting responsibilities.” Therefore, possible inclusion criteria are students who are taking a minimum of a certain number of credit hours, such as “12 credits hours,” and have custody of a child younger than the age of 18 who resides in their home
44
Describe how the researcher would determine the sample size
the researcher would run a power analysis to determine sample size
45
Elements
individual units of the population and sample
46
Target population
an entire set of individuals or elements who meet the sampling criteria.
47
sample
the selected group of people or elements from which data are collected for a study. (subjects, participants)
48
exclusion criteria
characteristics that can cause a person or element to be excluded from the target population
49
sampling in research
selection of a subject of a population to respresent the whole population
50
homogenous sample
as similar as possible to control extraneous variables
51
heterogeneous sample
represents a broad range of values -used when a narrow focus is not available
52
sampling error
difference between the population mean and the mean of the sample
53
random variation
the expected difference in values that occurs when different subjects from the sample are examined (the difference is random)
54
Which of the following has NOT been identified as a barrier to using research knowledge in nursing practice? A. findings are communicated primarily to other researchers B. Nursing studies have adequate replication C. Practitioners often do not value research D. Researchers-originated studies often do not solve pressing clinical problems
B. Nursing studies have adequate replication
55
what is the Grove Model for implementing EBP
nurses identify a practice problem, search for the best research evidence, and note that an evidence-based guideline has been developed to manage the problem -how guidelines are developed
56
What factors would you consider in instituting a practice change?
-will it take a long time -what support is needed to make the change -are there barriers to instituting the change in the agency
57
Types of Barriers
Clinical barriers: do not read research reports. lack education, biased, don't know how to implement findings Administration barriers: research not values, limited change in agency or change is not based on research, limited sources
58
translational research
an evolving concept - the translation of basic scientific discoveries into practical applications
59
PHR types
standalone (untethered): -lack interoperability with other systems and require manual data entry ex: Microsoft word, excel, google connected (tethered): EHR patient portal -direct communication with healthcare providers, ability to request medication refills, appointment self-scheduling, and integrations with several sources. ex: labs, providers
60
what are the key components of PHRs
information that is entered by the consumer and/or data from other sources - pharmacies, labs, and health care providers
61
Describe key factors leading to the widespread adoption of electronic PHRs.
62
technical implementation for PHRs
Data privacy and security -patients list privacy concerns when involving caregivers' proxy access Usability and user interface design -factors of usability testing - target goals Ease of interoperability -data exchange standards like continuity of care Data sources -EHR, pharmacies, social media
63
Summarize the challenges of adoption for PHRs.
Digital divide : Individuals of lower socioeconomic status, ethnic minorities, those with low eHealth literacy, and older individuals are less likely to adopt PHRs Provider engagement : Patient encouraged by the HCPs to use their online medical record were two times more likely to access their online medical record compared to those who weren’t encouraged Awareness of functionality : In 2018, patients said they did not have a need for an online medical record but increased awareness like self-scheduling and medication refills can drive adoption
64
evidence-based practice centers and translational research.
The evidence-based practice centers develop evidence reports and technology assessments on topics relevant to clinical and other healthcare organization and delivery issues – that are common, expensive, or significant - (AHRQ) Translational research is the process of turning observations in the laboratory, clinical, and community into interventions that improve the health of individuals and the public
65
what does IRB stand for and what does it do?
Institutional review boards (IRBs) are organized in universities and clinical agencies to examine the ethical aspects of studies before they are conducted -responsible for approving studies and addressing any research violations that may occur in a study exempt: no risk to subjects in a study expedited: minimal risk complete (full review): > than minimal risk
66
Who is Henrietta Lacks and how were her rights violated?
Her cervix tumor cells (cancerous) were LITERALLY just shared for research purposes. Not cool. They offer her cells “widely” to be basically experimented on
67
what are standards for ethics in the US
belmont report: -written in response to the Tuskegee Syphilis Study identified ethical principles w/ selecting subjects, informing risks and benefits and getting consent Tuskegee study - African American men w/ syphillis were studied without consent and were untreated
68
Measurement Error
systematic error: the variation in measurement is in the same direction and is not reliable random error: the difference is without a pattern ex: punching the wrong key when entering data into the computer
