Inter-Item Correlations - How to do?

[alexandra.elnick]

Using SPSS V13.0 how does one do inter-item correlations?  I did this
analysis many years ago in grad school but SPSS was DOS-based then.

I have a simple additive scale of 10 items and want to know which items
can be deleted from the scale.

Thanks,
Alexandra Elnick

Using the GUI
Analyze ----> Scale ----> Reliability Analysis.

Load the 10 items into the box to the right, and select the statistic you
want from the dropdown menu. By default it gives you chronbach's alpha.

Alexandra,

Look into the SPSS RELIABILITY program for item-total correlations,
estimates of internal consistency, and information about how the deletion of
specific items can improve the internal consistency of the scale.

Best,
