Demographic information for Study 1–2 (n = 1416).

<div><p>This study aimed to develop and validate a short-form version of the AWE-S (AWE-SF) within psychedelic samples, to reduce participant burden while maintaining psychometric integrity. Across five studies, we first replicated the original six-factor structure of the AWE-S through exploratory and confirmatory factor analyses (Study 1), leading to the creation of the 12-item AWE-SF (<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0314469#sec020" target="_blank">Study 2</a>–3). We then established the AWE-SF’s initial and predictive validity by correlating it with relevant emotional, psychedelic, and well-being outcomes (<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0314469#sec040" target="_blank">Study 4</a>–6). The AWE-SF demonstrated strong positive associations with positive emotions and was also linked to openness to experience. Moreover, the AWE-SF effectively predicted both mystical-type and challenging psychedelic experiences, as well as long-term well-being outcomes such as life satisfaction and psychological richness. In particular, the facets of connection and vastness were associated with positive emotional states and mystical-type experience, while accommodation and self-loss were associated with negative emotional states and challenging psychedelic experience. These findings suggest that the AWE-SF is a robust, reliable, and accessible tool for measuring awe experience.</p></div>
