Hello, I have a very time-sensitive question: I am replicating a theory that uses 12 Likert items to measure three latent variables (4 items per latent variable). Also in my study I use these 12 likert items that measure three latent variables. Every latent variables is measured by 4 Likert items. For my research, I have to combine/sum these variables into one measurement. So hat I have three variables as a result. My question/problem is: How can I combine these 4 Likert items into one scale, so that I have one number for each latent variable that I can use for my analysis? Some extra information: All the Likert item are measured on a 5-point-Likert scale. I have already run Cronbach's Alpha in SPSS and the 4 items have a very high Alpha. Also, the "corrected item- total correlation" is high enough. I want to use the three variables in a ordinal log regression analysis. Your help is greatly appreciated!

If you are asking how to compute sums and means, take a look at the followi= ng links: http://libguides.library.kent.edu/SPSS/ComputeVariables http://www.spss-tutorials.com/spss-sum-cautionary-note/ HTH.

hi anybody know this, how to find mean here my syntax CTABLES /VLABELS VARIABLES= q1_5_1 q1_5_2 q1_5_3 q1_5_4 q1_5_5 DISPLAY=LABEL /TABLE center[c] >( q1_5_1[c] [ROWPCT.COUNT F40.0] + q1_5_2[c] [ROWPCT.COUNT F40.0 ] + q1_5_3[c] [ROWPCT.COUNT F40.0] + q1_5_4[c] [ROWPCT.COUNT F40.0] + q1_5_5[c] [ROWPCT.COUNT F40.0]) /CLABELS ROWLABELS=OPPOSITE /CATEGORIES VARIABLES= q1_5_1 q1_5_2 q1_5_3 q1_5_4 q1_5_5 ORDER=A KEY=VALUE EMPTY=EXCLUDE LABEL ='BASE'.
