Health Indicators

Step 1: Define the characteristics of good health indicators. Step 1: Good health indicators should be Valid, Reliable, Sensitive, Specific, Feasible, and Relevant.
Step 2: Define each term and match it with the options.
Step 2:

Validity: This means the indicator measures what it is intended to measure. This matches option (A).
Reliability (or Reproducibility): This means the indicator yields the same results when measured by different people or on different occasions under similar conditions. This perfectly matches option (B).
Sensitivity: This refers to the indicator's ability to reflect changes in the health situation. This matches option (C).
Feasibility: This means the data required for the indicator can be practically obtained. This matches option (D).
Step 3: Conclude the correct definition for "Reliability".
Step 3: Reliability is the consistency and reproducibility of the measurement. Therefore, option (B) is the correct definition.
