Ayahuasca, a plant-based hallucinogen that serves as a spiritual medicine in South America, has improved depression in at least one placebo-controlled clinical trial. Case studies suggest that dramatic behavioral changes often follow the Ayahuasca ceremony, but most explanations of antidepressant effects focus on observed changes in mindfulness. The present study investigated if both mindfulness and behavioral activation might also contribute to these anti-depressant effects. We surveyed individuals (N = 152) about their changes in depressive symptoms, Behavioral Activation, and mindfulness after an Ayahuasca experience. Mindfulness was strongly associated with reduced depression severity (r = -.670, p < .001), while behavioral activation was moderately linked (r = -.474, p < .001). Changes in depressive symptoms (Center for Epidemiological Sciences Depression Short Form [CES-D-10]) covaried with subscales from the Five Facet Mindfulness Questionnaire [FFMQ] and Experiences Questionnaire [EQ], confirming previous findings (beta = -.57, [95% CI (- 5.70) - (- 3.25)], p < .001). In addition, a modification of the Behavioral Activation for Depression Scale-Short Form [BADS-SF] accounted for significant unique variance in the improvements in depression (beta = -.16, [95% CI (-6.32) - (-0.08)], p < .05). These results suggest that changes in behavioral activation likely serve as an important mechanism underlying Ayahuasca’s antidepressant effects. Future clinical trials could benefit from tracking behavioral activation. In addition, a concerted focus on increasing valued, positive activities might enhance Ayahuasca’s anti-depressant effects.

The present research examined job-related affective and cognitive processes across ages, and the role of trait mindfulness as a mechanism that influences the strength of these relationships. Specifically, job-related affective well-being, job satisfaction, and fluid intelligence were investigated as they relate to dynamics of aging. Participants on Amazon’s Mechanical Turk (N = 174) completed a two-time longitudinal survey separating individual difference tests of trait mindfulness and fluid intelligence at Time 1 from self-report assessments of job satisfaction and job-related affective well-being at Time 2. Overall, the results from this study provide strong evidence that age and mindfulness both play an …
