The Chinese version of OPTION scale: Is it reliable on measuring the shared decision-making among preoperative conversations.

Abstract

To test the reliability of the Chinese version of the OPTION¹² (OPTION¹²-C) scale; and to evaluate the level of shared decision-making (SDM) in the preoperative conversations for high-risk procedures by using the OPTION¹²-C. Two hundred and ninety-seven conversations were rated. Cronbach's alpha, Pearson's correlation coefficient and intraclass correlation coefficient (ICC) were used to assess the reliability of the OPTION¹²-C. Mean and median were applied to evaluate the scores. The Cronbach's alpha was 0.603. The Pearson's correlation coefficient of the sub-items ranged from 0.002 to 0.595; the inter-rater ICC was 0.992. The mean and median of the total scores were 9.61 ( ± 3.583) and 9 respectively. 430 family members appeared in the conversations. The reliability of the OPTION¹²-C was acceptable. The SDM behaviors of doctors were only scored at or close to the minimal skill level. High level of family involvement demonstrated the Chinese culture of family- centeredness. The OPTION¹²-C was proved to be applicable for testing the extent of SDM. The low level of SDM indicates a need to improve Chinese doctors' communication skills.
