I wish to analyze the following :
Predictor Variable (IV): Satisfaction of sexual needs as important (4 items scale and respond based on 4 point likert scale. Sum up to get the item score.)
Response Variable (DV): Condom usagae (2 options : never or sometime)
Questions:
-
Should I use binary logistic or multinomial logistic? (some people tell me to use multinomial logistic but a book said to only use it when the DV has more than two levels, and my DV only has 2 levels – never or sometime).
-
How can I use SPSS to analyse this? I need step by step help.
The SPSS dialog box for logistic regression has three boxes:
- Dependent : I put in Condom Usage
- Factor(s): (I am not sure should whether I put Satisfaction of sexual needs as important here?)
- Covariate : (I am not sure whether I should put Satisfaction of sexual needs as important here?)
I am very sorry. Maybe my question sounds silly but i really need help, as i am beginner. I couldn't get any tutor within my town.

A few points:
SPSS: I posted some links to tutorials in SPSS and R for conducting binary logistic regression.
