The PERMA-Profiler is a brief multidimensional measure of well-being, developed based on Seligman's PERMA model (Positive Emotion, Engagement, Relationships, Meaning, and Accomplishment). The development process involved creating a large item bank, reducing it to 15 core items, and adding eight filler items to assess overall well-being, negative emotions, loneliness, and physical health. The final 23-item measure was tested in multiple studies (N = 31,966) to evaluate its psychometrics, including model fit, internal and cross-time consistency, and validity. The PERMA-Profiler demonstrates acceptable reliability and validity, providing a tool for individuals to monitor their well-being across multiple psychosocial domains. The measure is particularly useful for its multidimensional approach, allowing for a more nuanced understanding of well-being and potential areas for improvement.The PERMA-Profiler is a brief multidimensional measure of well-being, developed based on Seligman's PERMA model (Positive Emotion, Engagement, Relationships, Meaning, and Accomplishment).
