Hi all, I am doing a study on the specific criminogenic needs of prolific offenders and I have come up with a fair bit of data. Using 1000 participants and logistic regression I found that those who re-offend have high drug misuse, alcohol misuse, financial management problems and attitude problems towards crime.

I am now performing a secondary phase and am trying to assess whether a specific programme can address these 4 needs. I have A categorical IV (whther they have taken the programme or not) and a categorical DV (Reoffender yes/no). I have measured the four variables for each participant along a continuous scale but I can't seem to find a way to do this using SPSS.

Is it possible to use continuous variables as covariates in what is essentially categorical data?

Thanks,

Mark.
