Solitude is often stigmatized, yet research suggests that intentional time alone can foster peaceful affect. This research tests 'Solitude Crafting,' a new two-part intervention to reshape emerging adults' experience by de-stigmatizing solitude and guiding meaningful solitary activities. Study 1 (N=120) assessed the intervention's feasibility and impact over five days. Study 2 (N=75) conceptually replicated the design, testing the Solitude Crafting intervention alongside a comparison time point in a nine-day, within-subject design . Results indicated immediate post-intervention improvements in emotional well-being, including a reduction in stress and increased high (e.g., happy) and low arousal (i.e., peaceful) positive affect (Studies 1 and 2), with tentative evidence suggesting sustained benefits (Study 2). Participants attributed increases in emotional well-being to the intervention, highlighting its efficacy. Our findings explore Solitude Crafting as a promising avenue for re framing attitudes towards solitude and enhancing well-being, laying the groundwork for future research on interventions to improve solitude time.
