Participants (<i>N</i> = 332), who were university students and members of the community, completed self-report measures of the key variables.

In the second, higher alexithymia was associated with greater difficulties regulating positive emotions, which was associated with higher levels of PTSD symptoms. The final pathway involved a serial mediation in which higher alexithymia was associated with lower self-compassion, and lower self-compassion was associated with greater difficulties in regulating negative emotions, which were associated with higher PTSD symptoms.
