I am trying to do my analysis for my work but getting very confused.

I am using multiple regression and have my dependent variable, which is fine. However, my two predictor variables are attachment and basic need satisfaction.

I have used the Experiences in Close Relationships questionnaire (ECR) and there are two scores for each participant; anxiety and avoidance. I was told to work out the mean for each, but I have no idea what I need to enter as my predictor variables, do I enter the mean score for anxiety and the mean score for avoidant into the same model? Or do I do one for avoidant and one for anxious?

Also, for basic need satisfaction, I have three traits, autonomy, relatedness and competence and was told to work out the average score for each. Do I enter the average scores for each?

Please help!

Thanks,

Ami
