# Association between event-related disclosure and posttraumatic growth: Targeting Japanese people, measuring attitudes toward disclosure, and examining event-related rumination as a mediating variable

## TL;DR

This study explores how sharing traumatic experiences relates to personal growth in Japanese adults, finding that disclosure can both help and hinder growth depending on the type of thinking it promotes.

## Contribution

The study introduces event-related rumination as a mediator linking disclosure to posttraumatic growth in a Japanese population.

## Key findings

- Willingness and resistance to disclose were linked to posttraumatic growth through deliberate and intrusive rumination.
- Willingness to disclose had larger effect sizes than resistance to disclose.
- Disclosure may enhance growth by promoting meaning-making but hinder it by reinforcing negative thoughts.

## Abstract

This study examined the association between event-related disclosure and posttraumatic growth (PTG). Specifically, it targeted the Japanese adult, assessed attitudes toward event-related disclosure, and examined event-related rumination as a mediating variable. A cross-sectional online survey was conducted among Japanese adults aged 20–59. Participants completed measures of demographic characteristics, stressful life events attributes, attitudes toward disclosure, event-related rumination, and PTG. Analysis of data from 480 individuals revealed that neither willingness to disclose nor resistance to disclose was directly associated with PTG. However, both willingness to disclose and resistance to disclose were positively associated with PTG through deliberate rumination and negatively associated with PTG through intrusive rumination. The effect sizes for willingness to disclose were approximately three times greater than those for resistance to disclose. These findings suggest that event-related disclosure may enhance PTG by promoting deliberate meaning-making processes, while also potentially hindering it by reinforcing involuntary negative thinking. Furthermore, these effects may be stronger when individuals are more proactive and disclose more frequently. These results have important implications for interventions aimed at enhancing PTG through event-related disclosure.
