Objective       To investigate the characteristics of posttraumatic growth and its correlation with positive/negative attention bias and self-acceptance in a marine corps.      Methods       Posttraumatic growth inventory (PTGI)

attention to positive and negative information scale (APNIS) and self acceptance questionnaire (SAQ) were surveyed in 672 marines obtained by convenient sampling.      Results       ①The score of PTG were 55.64±18.41 in the marine member. The members who having a military service for less than 2 years had the lowest score of PTG

and those for 3-5 years and 6-8 years had significantly increased PTG scores with the increase of military service length (F=8.69

P0.01). However

the PTG score of those with 8 years’ service was higher than that with 2 years’ service

but below than those with 3-5 years’ and 6-8 years’ service. ②The subscale itemsand total scores of PTG were positively correlated with the scores of self-acceptance

positive others and positive self (r=0.17-0.48

P0.05

P0.01)

but no such correlation was found with negative attention bias (P0.05). ③Regression analysis showed that attention to positive and self-acceptance could well predict posttraumatic growth

with a rate of 28.7%. ④Attention to positive and self-acceptance had direct positive impact on posttraumatic growth. The positive attention affected self-evaluation and positive self

positive self affected self-acceptance

and all had indirect positive influence on posttraumatic growth.      Conclusion       Culturing positive attention and improving self-acceptance will promote posttraumatic growth in marine members.
