Objective        To study the correlation of posttraumatic growth with emotion regulation

coping style and self-efficacy in cancer patients.       Methods        Posttraumatic growth

emotion regulation

coping style and self-efficacy in 216 cancer patients (including 56 patients with cervical cancer

32 patients with ovarian cancer

14 patients with trophoblastic tumor

40 patients with esophageal cancer

22 patients with lung cancer

38 patients with breast cancer

4 patients with nasopharyngeal carcinoma

3 patients with bladder cancer

and 7 patients with liver cancer)  in Department of Oncology

Xinqiao and Southwest Hospitals

were assessed according to the posttraumatic growth inventory（PTGI）

emotion regulation scale（ERS）

simplified coping style questionnaire（SCSQ）

and general self-efficacy scale（GSES）

respectively.       Results        The total posttraumatic growth score was 49.83±21.90

with an interpersonal score of 17.82±7.97

a new possibility score of 11.33±6.11

a personal power score of 9.66±5.01

a mental change score of 3.65±2.32

and an appreciate life score of 7.35±3.31

respectively. The scores of abreaction adjustment

inhibition adjustment

active coping and self-efficacy were significantly higher in higher posttraumatic growth score group than in lower posttraumatic growth score group（P0.01）. The posttraumatic growth was positively correlated with the abreaction adjustment

inhibition adjustment

active coping and self-efficacy in cancer patients（r=0.447、0.361、0.583、0.585，P0.01）. The active coping

abreaction adjustment and self-efficacy could effectively predict the posttraumatic growth in cancer patients with an explanation rate of 48.5%.       Conclusion        The emotion regulation

coping strategies

and self-efficacy are closely correlated with the posttraumatic growth in cancer patients

and can thus be used as important predictive factors for posttraumatic growth in cancer patients.
