“…There are also reasons to suspect that the intervention effects may vary depending on socioeconomic status or other sociodemographic factors and that our findings may not be generalizable to a broader population. Most previous research on optimism or related factors like purpose in life and health has found little evidence of effect modification by socioeconomic status or other sociodemographic factors (Boehm et al, 2020;Lee et al, 2021;Qureshi et al, 2022;Shiba et al, 2021). However, we suspect that limited resources might increase the likelihood of facing barriers that interfere with individuals' ability to translate their optimism or other facets of positive psychological well-being into action.…”

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 increases in short-term optimism and positive affect relative to the control group. Although the intervention had limited effects on physical activity and stress reactivity, more optimistic language in the essays predicted increased physical activity and decreased stress reactivity.
