How do you interpret intraclass correlation?
A flowchart showing readers how to interpret ICC in published studies. Values less than 0.5 are indicative of poor reliability, values between 0.5 and 0.75 indicate moderate reliability, values between 0.75 and 0.9 indicate good reliability, and values greater than 0.90 indicate excellent reliability.

Specify Analyze>Scale>Reliability Analysis. Specify the raters as the variables, click on Statistics, check the box for Intraclass correlation coefficient, choose the desired model, click Continue, then OK.
What is intraclass correlation in statistics?
In statistics, the intraclass correlation, or the intraclass correlation coefficient (ICC), is a descriptive statistic that can be used when quantitative measurements are made on units that are organized into groups. It describes how strongly units in the same group resemble each other.
What does ICC mean in statistics?
Intraclass correlation
Intraclass correlation measures the reliability of ratings or measurements for clusters — data that has been collected as groups or sorted into groups. A related term is interclass correlation, which is usually another name for Pearson correlation (other statistics can be used, like Cohen’s kappa, but this is rare).
How do you interpret Cronbach’s alpha in SPSS?
The steps for interpreting the SPSS output for Cronbach’s alpha
- Look at the Reliability Statistics table, in the Cronbach’s Alpha column.
- Look in the Item-Total Statistics table, in the Corrected Item-Total Correlation, record every item that has a value LESS THAN .
- If the alpha coefficient was LESS THAN .
How do you check for reliability in SPSS?
To test the internal consistency, you can run the Cronbach’s alpha test using the reliability command in SPSS, as follows: RELIABILITY /VARIABLES=q1 q2 q3 q4 q5. You can also use the drop-down menu in SPSS, as follows: From the top menu, click Analyze, then Scale, and then Reliability Analysis.
What does an ICC tell you?
What is a good intraclass correlation coefficient?
The ICC is a value between 0 and 1, where values below 0.5 indicate poor reliability, between 0.5 and 0.75 moderate reliability, between 0.75 and 0.9 good reliability, and any value above 0.9 indicates excellent reliability [14].
