Integration of Well-Being Therapy and Positive Psychotherapy: A Response to Fava and Guidi's (2021) Commentary on Radstaak et al. (2020)

The results of our study on the effects of well-being therapy (WBT) compared with a treatment-as-usual (TAU) control condition among individuals with residual symptoms of posttraumatic stress disorder (PTSD) were recently published in the Journal of Traumatic Stress (Radstaak et al., 2020). In a subsequent commentary, Fava and Guidi (2020) raised several conceptual and methodological issues that they asserted potentially limited the interpretation of the results. In this response, we aim to clarify these issues, thus contributing to the optimal interpretation of the findings.
