Friends,

My sincere apologies if this question has been posted earlier. I am looking for help in terms of how to do Intraclass Correlations and find out how to do within group reality in SPSS.

I am currently pursuing my PhD in Strategy and being 50 years old, I am just not able to understand the formulas given in Bliese & Haverson (1996).

My situation is this. I have done survey on team performance and other team capabilities within my service organization. I have got responses from 210 Team leads) and from 2+ team members under each of these leads. The Team lead has also given their opinion on team performance (7 point likert scale) and the team members have also done the same.

I am now choosing Team as my unit of analysis and hence I am aggregating the individual team member responses to each item to get a mean score at the team level from the team members.

As mentioned earlier, a team can consist of anywhere between 2 and 5 members apart from the team leader with the Average team member / team being around 2,7 or so.

Since i am not planning to to Multi Level modelling, I have decided to go this route based on similar work done by

Groves, K. S., & Feyerherm, A. E. (2011). Leader Cultural Intelligence in Context: Testing the Moderating Effects of Team Cultural Diversity on Leader and Team Performance. Group & Organization Management, 36(5), 535–566.

Now I want to do this with the data in SPSS.

Pls let me know if you know how to do the same.

Thanks in advance.

Intraclass correlations in SPSS for a multilevel model are not currently computed directly. However, you can get the needed parts and do it by hand.

The ICC is a proportion of variance:

     Mean Square(Between Groups) - Mean Square(Within)
-----------------------------------------------------------
 Mean Square(Between) + ((#groups-1) * Mean Square(Within))

Use the MIXED procedure, like this:

MIXED Y /PRINT=SOLUTION TESTCOV
 /RANDOM INTERCEPT | SUBJECT(GROUP) COVTYPE(VC).

to get the Mean Squares.

I found a video which looks to me like it uses MIXED to do a multilevel model:
