Objective To explore the level of posttraumatic growth （PTG） among patients at the early stage of accidental injury, and to analyze the relation with self-disclosure. Methods Three hundred and twenty patients suffering from accidental injury within 90 days were surveyed by using the Ambivalence Over Emotional Expression Questionnaire （AEQ）,Berkeley Expressivity Questionnaire （BEQ） and Chinese version of Posttraumatic Growth Inventory （PTGI-C）. Results The total PTGI score was 41.89±13.06, and that was positively correlated with positive expressivity, negative expressivity, positive impulse strength and negative impulse strength.After controlling for demographic variables,positive impulse strength and negative impulse strength could predict PTG (P＜0.05 for both). Conclusion Post-traumatic growth among patients at the early stage of accidental trauma was at low to mode-rate level. Clinical nurses should identify PTG as early as possible, and encourage the injured patients to express their emotions deeply to promote their personal growth.
