A researcher is assessing the reliability of a new instrument that was constructed to measure pain perception following cardiac catheterization.
The Cronbach's alpha obtained from a pilot study of the tool was 0.35. Which evaluation does the alpha value indicate?
There is a moderate amount of inter-rater reliability for this tool.
The instrument needs revision due to a lack of internal consistency.
The tool will consistently measure pain perception in clients.
Numerous inverse relationships exist among items on the scale.
The Correct Answer is B
Choice A rationale:
Cronbach's alpha is a measure of internal consistency, not inter-rater reliability. Inter-rater reliability assesses the degree of agreement between different raters or observers, which is not applicable in this context.
Choice B rationale:
This is the correct answer. A Cronbach's alpha value of 0.35 indicates poor internal consistency for the instrument. In other words, the items in the tool do not consistently measure the same underlying construct (pain perception). A low alpha value suggests that the items in the instrument may not be reliably measuring the intended concept and that revision may be necessary to improve the tool's consistency.
Choice C rationale:
The statement "The tool will consistently measure pain perception in clients" is not supported by the low Cronbach's alpha value of 0.35. A low alpha suggests that the tool does not demonstrate consistent measurement of pain perception.
Choice D rationale:
Cronbach's alpha does not provide information about the presence of inverse relationships among items on the scale. It assesses internal consistency, which is about the degree to which items on the scale are interrelated and measure the same construct. A low alpha indicates poor internal consistency but does not specifically indicate the presence of inverse relationships.

Correct Answer is C
Explanation
Choice A rationale:
Review the hospital's definition of workplace violence. Rationale: This is a reasonable step to take, but it does not directly address the issue of reporting workplace violence anonymously, which was the primary finding in the study.
Choice B rationale:
Repeat the study at the nurse manager's hospital. Rationale: Repeating the study may provide local data, but it does not immediately address the need for an anonymous reporting system, which is important for addressing workplace violence.
Choice C rationale:
Develop a system for reporting workplace violence anonymously. Rationale: This is the best course of action based on the study findings. Creating an anonymous reporting system can encourage nurses to report incidents without fear of reprisal, which is important for addressing workplace violence.
Choice D rationale:
Encourage peer support among the nursing staff to report issues. Rationale: While encouraging peer support is important, it may not directly address the need for an anonymous reporting system, which is the primary concern based on the study findings.
Correct Answer is C
Explanation
Choice A rationale:
The review of the literature section provides an overview of existing research and background information related to the study's topic. It does not typically present study findings or results.
Choice B rationale:
The methodology section outlines the research methods, design, and procedures used in the study but does not present the study's actual findings.
Choice C rationale:
This is the correct answer. The sentence, "Distress after a natural disaster was high at 3 months and decreased monthly for a majority of the participants, although one-third of the survivors had higher distress at 13 months than at 3 months," appears in the results section. This section is dedicated to presenting the study's empirical findings and data.
Choice D rationale:
The discussion section is where researchers interpret and discuss the implications of their study's findings. It does not typically present the actual findings or data.
