Background: With the great development of liver transplantation in China, long survival and quality of life after liver transplantation have been matters of growing interest. This study was designed to investigate the impact of personality and coping skills on the quality of life after liver transplantation.

Methods: Fifty-five outpatients who had been followed up after liver transplantation at our center were assessed by general quality of life inventory (GQOLI-74), a medical coping modes questionnaire (MCMQ), an eysenck personality questionnaire (EPQ), and a general condition questionnaire(GCQ).
