Help: How to transform indicators to one dependent variable?

#1
Hi

I am currently trying to transform 4 indicators from the world value survey to build one dependent variable to run regressions against.

I am wondering if I am doing this correct, since I am a statistics beginner in SPSS?

1. Step one is that I have transformed old data and variables into new z-score variables inbetween -2.5 to 2.5.

2. Then I am trying to do something like this:
weight1 = 0.25
weight2 = 0.5

((variablename1 * weight) + (variable2 * weight) + (variable3 * weight2) + (variable4 * weight2)) / 4

I am wondering if this is the correct way to transform variables into one dependent variable?

Cheers
