While reading a research report, the nurse discovers that the researcher used a study instrument that has an established correlation coefficient of 0.54. How should the reader interpret this information?
1. This information is not pertinent to the critique of the study.
2. This instrument is not very reliable.
3. This is a very valid instrument.
4. The instrument is very reliable.

Rationale 1: This information is very pertinent. If the study instrument is not reliable, the data may not be reliable.
Rationale 2: Correlation coefficients can range between –1.00 and +1.00 and are a measurement of reliability. It is risky to use an instrument with reliability lower than 0.70.
Rationale 3: The correlation coefficient should be above 0.70 to be a valid instrument.
Rationale 4: The correlation coefficient should be above 0.70 to be a reliable instrument.
