In nursing research, vignettes are used
less and extensively utilized in psychological social
sciences. It is a type of self reported qualitative
research where case scenarios, situations are given to
the research participants and their perception,
opinions, beliefs, and attitudes are elicited within the
vignettes. In certain research, text or pictures
presented to participants to prompt responses to
interview questions. ECG is a frequent safe and
inexpensive procedure that supports arrhythmias and
ischemia diagnosis. Nurses are usually the first to
conduct an ECG and therefore need to know how to
interpret it, but many nurses lack ECG Interpretation
Aim: The aim of this article is to describe the
sequential steps of case vignette tool on ECG and its
interpretation prepared for nursing students.
Materials and Methods: Development of this tool
involves three phases which are: the conceptualization
phase, the preliminary item evaluation phase and the
scale refinement phase. This case vignette tool
development is a part of large-scale study employed a
tri-phase which aims to determine ECG Interpretation
skills among nursing students. The developed case
vignette was submitted to the experts in the field of
nursing and medicine. The content validity ratio and
content validity indexed was computed. Further,
reliability was calculated. Pretesting was done to rule out
the feasibility of tool.
Results and findings: The computed content validity
index and content validity was found to be +1
respectively, which indicates that the developed tool
is highly valid. The internal consistency of the tool
was calculated by using Cronbach’s alpha correlation
coefficient its value was 0.86 which indicates the tool
is highly reliable.
Conclusion: This study identified the dimensions of the
case vignette and contributed to advancing the
measurement of the ECG interpretation skills among
nursing students. The case vignette is a brief and costeffective instrument that can measure skills of nursing
students on ECG interpretation.
