A score of 0 is a good decision, and a score of 100 is the worst decision. total score were 0 to 1600 points.
• Decision self-efficacy scale [ Time Frame: 1 week ]
  The scale included 11 questions, and participants were asked to think about how confident they were in making informed choices in 11 situations. The scoring for each situation is scored on a Likert scale with 0-4 points (very agrees to very disagree) for each question, then multiplied by 25 so that each question may score 0-100 points. The higher the score, the more confident participant are. Each question 0 points is not confident, 100 points is very confident. total score range is 0- 1100 points
• Satisfaction with Decision Instrument [ Time Frame: 1 week ]
  The content consists of 6 items, with a score of 1-5 points (very strongly disagreed and very agreeable) for each question. The score may be 6-30 points. The higher the score, the higher the satisfaction with the decision. A score of 6 indicates that the extreme dissatisfaction of 30 points indicates extreme satisfaction.
• Decision Regret Scale [ Time Frame: 3 months later ]
  There are 5 questions in the content of the scale. The scoring of each situation is scored on the Likert scale with 0-4 points (very agree and very disagree) for each question. The first question, the third question and the fifth question are The forward question, in which the second and fourth questions are reverse questions, need to be scored in reverse, then multiplied by 25, so that each question may score 0-100 points. The higher the score, the more regret it is. Total score is 0-500 points.

• Satisfaction With Decision Instrument [ Time Frame: 1 week ]
  The content consists of 6 items, with a score of 1-5 points (very strongly disagreed and very agreeable) for each question. The score may be 6-30 points. The higher the score, the higher the satisfaction with the decision. A score of 6 indicates that the extreme dissatisfaction of 30 points indicates extreme satisfaction.

Aim: Explore the effectiveness of sharing decision-making program interventions in the early stage of HCC to reduce treatment decisions conflicts and improving decision-making satisfaction.

Design: An experimental design will be used in the study. The 102 primary liver cancer patients, who were diagnosed with Barcelona stage(BCLC stage) 0-A, will be recruited and randomized to the control or intervention group. The intervention measures in this study "sharing decision-making plan" mainly includes sharing the decision-making talks and the decision-making assistance tools used in the process.

The effectiveness of sharing decision-making program interventions in the early stage of HCC to reduce treatment decisions conflicts and improving decision-making satisfactionHepatocarcinoma (HCC) is a high incidence and high mortality disease. Hepatocarcinoma is also a very common disease in Taiwan. Treatment options are limited to those patients with advanced Hepatocarcinoma. However, there are many options for patients with compensated cirrhosis, and small liver tumors are potentially resectable. When patients understood the detailed assessment of the disease both doctors and patients can set the best treatment goals. Sharing decision-making is a patient-centered collaborative processes that enable individuals and their healthcare providers to make decisions together, but patient engagement appears to be less optimistic and there is a lack of evidence that the link between sharing decision-making measures and patient behavior and health outcomes. When decisions are made under social stress or time constraints, people may make less than optimal decisions when they lack sufficient information or skills. Since then the treatment does not match the expected results, often result in decision regrets or arguments with the medical team, and even evolved into medical lawsuits. Therefore, the purpose of this study is to explore the effectiveness of sharing decision-making program interventions in the early stage of HCC to reduce treatment decisions conflicts and improving decision-making satisfaction. In this study, investigators took the experimental design to assess the cases of early hepatocellular carcinoma in hepato- gastroenterology, surgery and oncology clinical in a teaching hospital in the eastern part of Taiwan.

The intervention measures in this study "sharing decision-making plan" mainly includes sharing the decision-making talks and the decision-making assistance tools used in the process. According to Elwyn et.al. (2012), the decision-sharing model was proposed to intervene in the treatment decision-making of early liver cancer patients, including Choice talk, Option talk, Decision talk, and decision-making. Decision support for the process, where the investigator meets with the patient and its important others in the interdisciplinary discussion room or ward meeting room.

Second, decision assistance tools. Decision assistance tools provide information about options and outcomes, and clarify personal values to help people participate in decision making. The aim is to supplement, rather than replace, medical staff counseling (Collins et al., 2009), and the quality of decision aids is very important. Satisfaction with the use of tools is associated with increased patient satisfaction and reduced decision-making. Patients can benefit from computerized decision-making tools without the need to increase physician involvement.

The research tools include basic population data, clinical stage of disease, self-efficacy scale of hepatocellular carcinoma, Decision Decision Confidence Scale (DCS), decision self-efficacy scale , Decision Satisfaction Scale and Chinese Simplified-form Mandarin Health Literacy Scale.

The obtained data were collected and analyzed by SPSS20.0 for Window software. The main statistical methods include descriptive statistics, T-test, analysis of variance, Pearson Product Moment correlation coefficient and Generalized Estimating Equations (GEEs) ).
