# The assessment of psychological richness, meaning, and happiness with social media text data: Predictive accuracy and distinct behavioral correlates

## TL;DR

This paper explores how well social media text can predict different aspects of well-being, finding that psychological richness is uniquely linked to specific language patterns.

## Contribution

The study introduces psychological richness as a new well-being dimension with distinct linguistic predictors compared to hedonic and eudaimonic well-being.

## Key findings

- Language features improved prediction accuracy for psychological richness but not for hedonic or eudaimonic well-being.
- Psychological richness had the lowest prediction accuracy (r = .21) compared to other well-being dimensions.
- Linguistic features associated with psychological richness showed discriminant validity with unique content and direction.

## Abstract

Assessing well-being with social media text data is a promising method, but besides hedonic well-being, little is known about whether additional well-being dimensions, such as psychological richness and eudaimonic well-being, can be predicted from such data. We compare the predictive accuracy for hedonic well-being, eudaimonic well-being, and the recently proposed construct of psychological richness in a large sample of Facebook users (n = 2,644), and find that the inclusion of language features incrementally improved model prediction accuracy beyond demographic features for psychological richness, but not for hedonic or eudaimonic well-being. Psychological richness had the lowest overall prediction accuracy (r = .21) followed by hedonic well-being (r = .27) and eudeomonic well-being (r = .29). The linguistic features associated with Psychological Richness were face valid, and in many instances the content and direction of the associations were unique to Psychological Richness, which provides discriminant validity evidence.
