Which of the following is NOT true related to the reliability of a measuring tool?
Appeared in: RUHS, Jaipur, M.Sc Nursing Entrance Exam-2016
Explanation
- Efficiency is not a measure of a tool's reliability; it relates to the practicality of its use.
- Reliability is a psychometric property that refers to the consistency, dependability, and repeatability of a measurement tool.
- Efficiency pertains to the practical aspects of using the tool, such as the cost, time, and effort required for its administration and scoring.
Why Other Options Were Wrong
- Option B: Equivalence is a core attribute of reliability.
- Option C: Internal consistency is a core attribute of reliability.
- Option D: Stability is a core attribute of reliability.

Clinical Relevance
- Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Attributes of reliability in research measurement tools as background academic context rather than a clinical decision trigger.
- Nurses must critically appraise research for evidence-based practice, which includes evaluating the reliability of the measurement tools used in studies to ensure the findings are dependable.
- Using an unreliable tool in a clinical setting, such as a pain scale with low inter-rater reliability, can lead to inconsistent patient assessments, poor communication among staff, and ineffective care planning.
- What if a hospital wants to implement a new patient fall risk assessment tool? If the tool has high reliability but is very complex and time-consuming (low efficiency), nurses may not use it correctly or consistently, paradoxically increasing patient risk.
How to Approach the Question
- First, identify the negative keyword 'NOT' in the question. This signals that you are looking for the option that does not belong to the group.
- Recall the definition of 'reliability' in the context of research and measurement. It is fundamentally about consistency and repeatability.
- Systematically evaluate each option against this definition.
- Stability (consistency over time), Equivalence (consistency between raters/forms), and Internal Consistency (consistency among items) are all established types of reliability.
- Consider 'Efficiency'. This term relates to practical constraints like cost, time, and effort, not the consistency of the measurement itself.
- Conclude that 'Efficiency' is the outlier and therefore the correct answer to the 'NOT' question.
Concept Tested & Keywords
- Concept Tested: Attributes of reliability in research measurement tools
- Stem keywords: reliability, measuring tool
- Lead-in keywords: NOT true
- Negative lead-in flag: The question asks to identify the term that is NOT an attribute of reliability.
