I am wondering if I have to use the multiple regression analysis or the multivariate regression analysis. I am looking at the effects of parental support, big 5 (openness, conscientiousness, extraversion, agreeableness, neuroticism), and friendship on the affective well being of adolescents. I want to split affective well being into positive and negative affect. That means I will have 2 dependent variables and 3 independent variables. But for some other hypotheses I would like to know the effect on affective well being, so negative and positive affect taken together with 1 dependent variable.
also, I want to look at gender as moderator on the effect of parental support on affective well being.
i am not sure which analyses I need to use. Any tips?
