Positive interventions in depression change the structure of well-being and psychological symptoms: A network analysis

Although positive psychology interventions increase well-being and reduce depression, little is known about whether they facilitate a reorganization of the connections between psychological elements. We used Network Analysis (NA) to explore the topography of changes in psychological elements after a Positive Psychology Intervention (PPI) and a Cognitive-Behavioral Therapy (CBT) program for depression. Clinically depressed women were blindly allocated to a PPI (n = 45) or CBT (n = 48) 10-week group treatment. NA showed that the PPI program was the only one that significantly changed the structure of the network for psychological elements. The results showed that hedonic and eudaimonic elements played a substantial role in the reorganization of the network, becoming key connecting elements between the group of clinical variables and the group of positive functioning variables. Our findings support, from the NA perspective, the unique contributions of positive intervention programs to change the complex patterns of relationships between symptoms and positive variables.
