--- - |2+ Abstract Objective Solitude is a ubiquitous experience, often confused with loneliness, yet sometimes sought out in daily life. This study aimed to identify distinct types of solitude experiences from everyday affect/thought patterns and to examine how and for whom solitude is experienced positively versus negatively. Method 100 community‐dwelling adults aged 50‐85 years (64% female, 56% East Asian, 36% European, 8% Other/Mixed heritage) and 50 students aged 18‐28 years (92% female, 42% East Asian, 22% European, 36% Other/Mixed) each completed approximately 30 daily life assessments over 10 days on their current and desired social situation, thoughts, and affect. Results Multilevel latent profile analysis identified two types of everyday solitude: one characterized by negative affect and effortful thought (negative solitude experiences) and one characterized by calm and the near‐absence of negative affect/effortful thought (positive solitude experiences). Individual differences in social self‐efficacy and desire for solitude were associated with everyday positive solitude propensity; trait self‐rumination and self‐reflection were associated with everyday negative solitude propensity. Conclusions This study provides a new framework for conceptualizing everyday solitude. It identifies specific affect/thought patterns that characterize distinct solitude experience clusters, and it links these clusters with well‐established individual differences. We discuss key traits associated with thriving in solitude. This article is protected by copyright. All rights reserved. - Journal of Personality, Volume 0, Issue ja, -Not available-.
