“…It is characterized by victims (or witnesses) of trauma experiencing intrusive thoughts (e.g., nightmares or difficulties concentrating), avoidance behaviours (e.g., avoiding activities that might remind them of the trauma), negative alterations in cognition and mood (e.g., persistent and distorted blame of self or others, and persistent negative emotional state), and alterations in arousal and reactivity (e.g., reckless or self‐destructive behaviours, hypervigilance, and exaggerated startle responses; American Psychiatric Association, ). Empirical evidence showed that social support could have buffering effects on PTSD (Adams & Boscarino ; Andrews, Brewin, & Rose, ; Avery & McDevitt‐Murphy, ; Guay, Billette, & Marchand, ; Guay et al, ; Laffaye, Cavella, Drescher, & Rosen, ; Pietrzak et al, ; Schnurr, Lunney, & Sengupta, ). Specifically, lack of social support after the traumatic event is one of the strongest social factors that predicts PTSD.…”
