Coding of 5 point scale ie Never, rarely, sometimes, very often and always into spss and analysis there off

[Avantika Bakshi]

Dear Sir

I am primarily studying extent of ICT tools usage, and if it varies across organisations in the study area (based on organisation profile variable).

 I am also studying its impact on an outcome ( business performance). My scale for ICT usage is 5 point scale namely,  Never, rarely Sometimes, very often and always, while that of performance and other variables is "S. Disagree to S. Agree scale. 

I have the following questions-

a) Since the scale measures extent of usage and Never (1) signifies no usage, should I code them as 0 in  spss or as 1? What should be interpreting criteria in that case? Can I apply EFA on this then. 

b) When studying the relationship between extent of usage and performance, do i need to convert the scores as they are measured on different scales or can i proceed simply by taking the mean of them each.  Both extent of usage and performance are multidimensional. 

Thanking you in anticipation.

Dear Avantika

Here are my inputs:

1. Prefer coding by 1 instead of zero. 

Never (1), Rarely (2), Sometimes (3), Very often (4), and Always (5)

Take the mean of each statement, a higher mean indicates higher usage.

You can apply EFA to such data.

2. When we compute correlation or regression, almost all software (without asking us) converts our data into z-scores which are between -3 to 3. Hence it does not matter whether we used 5 point scale or 7 point scale.

Best wishes

Thankyou sir. I wanted to reconfirm one thing.
Can EFA  be applied on data coded as 0, 1,2,3,4 ,  or doing so would be an assumption breach in totality.
