Step-wise logistic regression using SPSS

An HIV researcher explored the factors that influenced condom use with a new partner (relationship less than 1 month old). The outcome measured was whether a condom was used (Use: condom used =1, used = 0). The predictor variables were mainly scales from the Condom Attitude Scale (CAS) by Sacco, Levine, Reed, and Thompson (1991). Gender; the degree to which the person views their relationship as 'safe' from sexually transmitted disease (Safety); the degree to which previous experience influences attitudes towards condom use (Sexexp); whether or not the couple used a condom in their previous encounter, 1= condom used, 0 = not used, 2 = n previous encounter with this partner (Previous); the degree of self-control that a person has when it comes to condom use (Selfcon); the degree to which the person perceives a risk from unprotected sex (Perceive). Previous research (Sacco, Rickman, Thompson, Levine, & Reed, 1993) has shown that gender, relationship safety and perceived risk predict condom use. Carry out an analysis using Condom.sav to verify these previous findings, and to test whether self-control, previous usage and sexual experience predict condom use.
Can someone help me with completing a SPSS logistic multiple regression analysis for the above exercise using the condom.sav dataset from the Field text. I have to report the findings in APA format according to the guidelines in the PASW Application Assignment Guidelines handout. My SPSS output is attached. I do not know if it is correct.
