"It is notable that no subjects reported any harm from study participation and all of them reported some degree of benefit. Consistent with the investigators‘ clinical observations in the original study, the responses we obtained on the questionnaire indicated that participants often experienced benefits beyond decreased PTSD symptoms. This is not a radical idea; many forms of psychotherapy produce benefits in terms of psychological growth and development that are not limited to improvements in a specific disorder that may have been the original target of therapy (Tedeschi and Calhoun, 2006; Zoellner and Maercker, 2006). Such benefits may prove to be a particularly prominent and valuable feature of MDMA-assisted psychotherapy. Some of the areas of benefit that were endorsed on the LTFU [Long Term Follow Up] Questionnaire, such as an increased self-awareness, improved relationships, an enhanced spiritual life, and more involvement in the community or world, represent effects that are not fully measured by the PTSD symptom scales."
