- THE 3638323 TO 1605548 A 1450464 OF 1443430 AND 1443154
- Intraclass Correlations (ICC) and Interrater Reliability

Therefore, the total score distributed across each of the four culture totalled 655, and each person rates each culture such as 75, 55, 65, 65. I would like to create overall organizational culture scores for each company by averaging (aggregating individual responses). One company, for example, will have 85, 65, 75, 85 scores of each culture type.

We now wanted to calculate the interrater reliability and were wondering:

6: If an ICC would be a good test for this (considering that my variables are categorical rather than numerical)?

7: How we should we code our variables? I have now used a wide format with the raters in rows and picture 6 6 in columns. With variables being 5, 6, 7 or 8. Would it also be possible (or even favourable) to code them as correct or incorrect?

8: What model we should use? Reading the original article, I would think two-way random. What is the difference between the two 8766 types 8767 ? (consistency or absolute agreement)

I would actually say that because you are coding 8775 presence 8776 of a measure, you are probably dealing with dichotomous (yes/no) data, in which case you should not use ICC at all you probably need either simple percentage agreement or Fleiss 8767 kappa.

Hello, thank you so much for this. I am completing a study at university where 7 assessors/judges have scored 8 videos with a colour category (one of four colours) how is this possible in SPSS. What does the data type and measure need to be in order for this to work?? Thank you so much.

Kind regards,

Rebecca

I want to use the instrument in a validation study to demonstrate the Arabic translation is valid and reliable. For validity, I will be running correlations with the actual number of medications to see if the scale has criterion related validity (increase in number of medications should go hand in hand with increase in complexity scores) and for reliability measurement I was thinking of performing ICC.

Thanks,

But Pearson’s correlation is not sensitive to systematic error. In my study rater has no effect because response of the patients is binary (Correct recall/Not correct recall). In test-retest reliability using ICC rater has replaced with trial. what is your opinion؟

In SPSS, you 8767 re going to want only 7 columns of rater data associated with each case. You should not leave the data in the original 8-column format, or SPSS will assume you have missing data (which you don 8767 t, based upon your design). So you 8767 ll need to collapse your 8 raters into 8775 first rating 8776 and 8775 second rating 8776 columns, so that every case has exactly 7 ratings in exactly 7 columns.

ICC is going to assume that your three raters are all drawn from the same population. Thus, using ICC means that you expect the father, child, and mother to provide the same sort of information. If you don 8767 t think that 8767 s true and it doesn 8767 t sound like you do then you shouldn 8767 t do that. I would instead just use something like ANOVA and calculate an effect size. Eta-squared would tell you the proportion of variance in your ratings explained by their source, so I 8767 d probably recommend that.

I am looking at a 65-item teacher rating scale. 55 students were each rated by 7 different teachers however, the pairs of teachers were not the same for each student (. there were a total of 7 teachers, different pairs rated different students.) I am looking to calculate interrater agreement for the scale using mean scores. Would I need ICC because the raters are not the same? Could I use Pearson correlations instead?
