To compute Cronbach's alpha for a set of variables, use the ALPHA option in PROC CORR as follows:

  PROC CORR DATA=dataset ALPHA;
    VAR item1-item10;
  RUN;

To run the same test in SPSS and Stata, see ARCHIVED: In SPSS, how do I compute Cronbach's alpha statistic to test reliability? or ARCHIVED: In Stata, how do I compute Cronbach's alpha statistic to test reliability?
