Patterns of Natural Language Use: Disclosure, Personality, and Social Integration:

TLDR: The authors found that particular patterns of word use predict health and also reflect personality styles, and that language use in the laboratory writing paradigm is associated with changes in social interactions and language usage in the real world.

Abstract: When people write about their deepest thoughts and feelings about an emotionally significant event, numerous benefits in many domains (e.g., health, achievement, and well-being) result. As one step in understanding how writing achieves these effects, we have developed a computer program that provides a “fingerprint” of the words people use in writing or in natural settings. Analyses of text samples indicate that particular patterns of word use predict health and also reflect personality styles. We have also discovered that language use in the laboratory writing paradigm is associated with changes in social interactions and language use in the real world. The implications for using computer-based text analysis programs in the development of psychological theory are discussed.
