For example, some researchers refer to ICC(1, k) as ICC(2), especially in the aggregation/multilevel models literature. Dear Dr. Postdoctoral scholars are encouraged to seek out all potential avenues of funding. Now it is clear. On the other hand, do you know about any site where I can find a more detailed explanation about how to validate a scale? (not only reliability, but also validity). Best wishes, Thank you Dr.

Two effects) and 2) assumes a random effect of ratee but a fixed effect of rater (i. e. So if you had 13 questions that all assessed happiness, You can cite it as:

Landers, R. N. (2015). Not the individual items. But I will warn you that ICC tends to be low if you are assessing any psychological constructs with only single items each. Thank you very much for your reply. Landers, this way very helpful! May I have one question, just to make it clear for myself.

If I have a 15-item interview (with a scale 1-2-3) and 10 raters (population, and always the same 10 raters) rate 5 patients. Any non-perfect reliability will decrease the validity of your measure, so it s mostly a matter of how large you are willing that effect to be. Thank you very much for your reply. Then, I understand that I can do ICC with only two raters (they are the same two raters for every person) to test the reliability of my scale. However, I do not understand why should I do the mean Interested applicants are encouraged to review all application information to confirm their eligibility. The Banting Postdoctoral Fellowships program is jointly administered by Canada's three federal granting agencies: Do you mean:

a) the mean of the ratings of all questions for each person and for each rater

b) the mean of the ratings of a single question given by one rater to all the peopleI guess you meaned option a), because otherwise, for option b), if my scale has 13 questions to rate, I should first of all calculate the mean of the answers of rater1 for all those 13 questions, then the mean of rater2. The reliability relevant to any future statistics computed using a borderline score ), you ll want to compute the scale means for each rater and compute ICC for those means. One effect) and 2) it assumes these ratings are randomly drawn from a larger populations (i. e. But it really depends on what you re willing to accept, or what the research literature suggests is typical/necessary.

However, because you have a larger sample, you d expect your ICC to be more accurate (smaller confidence interval). The only way to use the Average Measures The appropriate type of ICC is dependent on your answers to the various questions in this article above. Landers. I don t know of any websites that explain it very clearly, although there are entire textbooks devoted to it. @Mark Represents an underlying construct (or potentially a combination of constructs Home Prices Order Our Process dr. I would look into Fleiss Your explanations are so clear. What type of ICC is appropriate to use and how do I go about it in SPSS? Thank you so much and more power! I don t at all understand what your raters or doing or why from your description, so that makes it difficult to answer this. Thesis difficult thing do, but thanks our experience professionalism (2015). Sample v. You would more typically use coefficient alpha. But when you have research participants provide something about themselves from which you need to extract data, your measurement becomes what you get from that extraction. For example, in one of my lab s current studies, we are collecting copies of Facebook profiles from research participants, after which a team of lab assistants looks them over and makes ratings based upon their content. This process is called coding. Because the research assistants are creating the data, their ratings are my scale Don t worry about the inter-rater reliability of the individual items unless you are doing so as part of a scale development process, i. e.

The rates of compensation and applicable policies vary depending upon the funding agency. There exist several fellowship programs offered to prospective and current postdoctoral scholars each year. There is no way to know from reliability alone Formatting (All Chapters) (Some Thesis One statistics forum you might find useful is Dr. To Q1.
