“…The majority of studies, most of them investigating online programs, suggest that PPIs can lead to an increase in well‐being, a reduction in symptoms of depression as well as anxiety, and an increase in subjective health (Antoine, Dauvier, Andreotti, & Congard, ; Bolier, Haverman, Kramer et al, ; Görges, Oehler, Hirschhausen, von, Hegerl, & Rummel‐Kluge, ; Seligman, Rashid, & Parks, ; Seligman, Steen, Park, & Peterson, ; Shapira & Mongrain, ; Wellenzohn, Proyer, & Ruch, ; see Bolier & Abello, ; Mitchell, Vella‐Brodrick, & Klein, for reviews) . Recent studies comparing PPI and CBT group therapies suggest that PPIs are as effective as CBT interventions in treating severe clinical depression, while leading to even greater satisfaction scores among patients (Chaves, Lopez‐Gomez, Hervas, & Vazquez, ; Lopez‐Gomez, Chaves, Hervas, & Vazquez, ). However, results were not consistent across studies as others did not observe an improvement concerning symptoms of depression (Abbott, Klein, Hamilton, & Rosenthal, ; Gander, Proyer, Ruch, & Wyss, ; Mitchell, Stanimirovic, Klein, & Vella‐Brodrick, ; Mongrain & Anselmo‐Matthews, ; Sin, Della Porta, & Lyubomirsky, ).…”
