Inclusion criteria: Women (≥18 years) with scores equal to or greater than 11 points on the EPDS (Cox et al., 1987) and who have been mothers in the last year. Exclusion criteria: those who: a) have been mothers in the last month (possible 'baby blues'); b) meet DSM-5 criteria for substance abuse and/or dependence in the 30 days prior to participation in the study and c) present a serious mental disorder that makes it difficult to follow the protocol (e.g. severe neurocognitive problems or brain damage; schizophrenia and other psychotic disorders). Participants will be randomly assigned to the CBT group or the PPI group. Both groups will be treated identically except for the type of intervention. Group assignment will be blind to both patients and investigators.~Intervention: Both interventions have 10 weekly sessions. Sessions will be in groups and online. CBT includes 3 modules: behavioral activation, cognitive restructuring, and interpersonal skills. CBT has been shown to be effective in reducing depressive symptoms and modifying attentional biases (Pearson et al., 2013).~On the other hand, a new protocol of positive interventions adapted for women after maternity (PPI) will be designed and applied. This multicomponent protocol includes interventions that have already been empirically validated in treating depression.
The objective of this study is to design and validate an online intervention aimed at promoting well-being in women with postpartum depression. For this, the design of a multicomponent protocol consisting of empirically validated positive interventions and comparing these with a group Cognitive Behavioral Therapy (CBT) is proposed, following the National Institute for Health and Care Excellence (NICE) recommendations for the treatment of depression. Participants will be screened for inclusion in the program if they meet clinical criteria. After that, they will be randomly assigned to a CBT group or a positive psychology intervention (PPI) group.
