Hi everyone!

In my thesis, I use partner gender (woman vs. man) as a between subjects independent variable and priming figure (partner vs. acquaintance) as a within subject independent variable. Dependent variable is negative affect recovery score (range: -5 and +5).

So my study design is a 2x2 mixed design.

Also, I gave all participants LGB Identity Scale and asked their relationship duration prior to the experiment. I planned to use LGB Identity Scale (1-7 Likert type) and Relationship Duration (in months) as control variables.

The problem is that two control variables are continuous and what they measure is completely different than what I measure in the experiment? therefore, I cannot imagine how these covariates can eliminate any effect from dependent variable?

Another question is which analysis to use?

Actually I need to understand the logic of any analysis method to interpret these variables.

Thank you!

(*I use Tabachnick and Fidell’s book you can also refer to a book page )
