Perceived social support mediates the relationships of dispositional mindfulness to job burnout and posttraumatic stress disorder among chinese firefighters.

OBJECTIVE
The present study investigated the ways in which dispositional mindfulness is related to posttraumatic stress disorder (PTSD) symptoms and job burnout among firefighters by considering the role of perceived social support.


METHOD
A total of 409 Chinese firefighters completed the PTSD Checklist for Diagnostic and Statistical Manual of Mental Disorders, fifth edition, the Maslach Burnout Inventory-General Survey, the Perceived Social Support Scale, and the Mindful Attention Awareness Scale.


RESULTS
Structural equation modeling indicated that our model fit the data well (χ² = 87.16, df = 27, p < .001, χ²/df = 3.23, comparative fit index = 0.97, Tucker-Lewis Index = 0.95, root mean square error of approximation [90% confidence interval] = 0.07 [0.06, 0.09]) and revealed that perceived social support partially mediated the relationship between dispositional mindfulness, PTSD, and job burnout.


CONCLUSIONS
Dispositional mindfulness had direct and indirect negative associations with PTSD symptoms and job burnout, and this relationship was mediated by perceived social support among firefighters. (PsycINFO Database Record (c) 2019 APA, all rights reserved).
