To explore the impact of cognitive evaluation, processing and social support on post-traumatic growth of patients with accidental trauma, and analyzed their impact path.

Cognitive evaluation scale, event-related rumination meditation scale, social support scale and Chinese version of post-traumatic growth questionnaire were used to conduct a cross-sectional survey on 336 patients with accidental trauma.

The total score of post-traumatic growth (PTG) of patients with accidental trauma (58.74±13.53) and the total score of purposeful rumination and total rumination were positively correlated with the total score of post-traumatic growth and all dimensions (r=0.578, 0.439, P<0.01); the total score of invasive rumination was negatively correlated with the total post-traumatic growth score (r=-0.144, P<0.01); the social support was positively correlated with the total post-traumatic growth score (r=0.492, P<0.01). Positive cognitive evaluation and purposeful rumination meditation played a partial mediating role between social support and post-traumatic growth. The mediating effect was 0.142, accounting for 13% of the total effect.

Social support not only directly predicted the post-traumatic growth, but also indirectly affected the post-traumatic growth through social support positive cognitive evaluation, and purposeful rumination.
