Tapping into feelings: An experience sampling study examining the dynamics of smartphone-based emotion regulation and...

This study examines digital emotion regulation as a dynamic process, involving both processes of media selection and media effects. Using a large intensive-longitudinal data set with more than 50,000 experience sampling data points gathered from over 1,000 adults, we investigated cross-lagged associations between negative affect and two smartphone-based strategies for regulating negative emotions, namely emotion expression and avoidance. Results indicate that individuals are more likely to engage in both smartphone-based expression and avoidance following negative affect (i.e., media selection). However, we observed no meaningful effect of smartphone-based emotion regulation on subsequent negative affect (i.e., media effects). Additionally, we explored the person-specificity of these associations, showing that media selection effects vary meaningfully across individuals, while media effect associations do not. Finally, using passively sensed behavioral smartphone data, we found that smartphone-based emotion expression partially explained the association between negative affect and mobile communication. Similarly, smartphone-based avoidance partially explained the association between negative affect and social media use. Overall, these findings suggest that while individuals may turn to smartphone-based strategies such as negative emotion expression and avoidance in response to negative emotional states, clear evidence of their short-term effectiveness in reducing negative affect is still lacking.
