In order to examine whether there are differences between the groups in the remission of the diagnosis of depression, the investigators will perform two Cochran-Mantel-Haenszel tests (one for the results obtained after the intervention and another for the results obtained after the follow-up). Similarly, in order to examine whether there is a response to treatment (reduction of at least 50% in the severity of depressive symptoms; Dimidjian et al., 2006), two other Cochran-Mantel-Haenszel testse will be carried out. Finally, in order to examine whether there are any differences between the groups in the percentage of women responding to treatment with regard to the intensity of pain, two more Cochran-Mantel-Haenszel tests will be performed. Treatment response will be considered if there are reductions of at least two units on the pain scale from 0 to 10, as this is the criteria usually employed for clinically significant pain improvement (Michener, Snyder, & Leggin, 2011). Finally, in order to test whether the decreases found after the follow-up in the pain-related variables are mediated by the decrease in depressive symptoms severity, regression analysis with bootstrapping will be conducted (Preacher & Hayes, 2008).
