Effects of Induced Optimism on Subjective States, Physical Activity, and Stress Reactivity.

ABSTRACT: This study examined effects of experimentally-induced optimism on physical activity and stress reactivity with community volunteers. Using an intervention to induce short-term optimism, we conducted two harmonized randomized experiments, performed simultaneously at separate academic institutions. All participants were randomized to either the induced optimism intervention or to a neutral control activity using essay-writing tasks. Physical activity tasks (Study 1) and stress-related physiologic responses (Study 2) were assessed during lab visits. Essays were coded for intensity of optimism. A total of 324 participants (207 women, 117 men) completed Study 1, and 118 participants (67 women, 47 men, 4 other) completed Study 2. In both studies, the optimism intervention led to greater increase
