Abstract
This study aimed to explore medical decision preference associated with
cancer treatment among Chinese descent individuals using four different medical
decision-making tasks. Additionally, this study also aimed to examine the framing
effect or how positively (e.g., tumors have shrunken, tumors can be removed) and
negatively (e.g., tumors did not shrink, tumors cannot be removed) conveyed medical
information to describe available treatment outcomes influence medical decision
preference. Furthermore, this study aimed to understand medical decision
preferences of participants based on psychological distance using the Construal
Level Theory (CLT) as framework. This quantitative study used two samples of
Chinese descent individuals, which were drawn from Penang, Malaysia (Sample 1)
and Kunming, Yunnan, China (Sample 2), respectively, and both samples completed
the same experiment. There were two groups in both samples. The cancer group
consisted of participants with a cancer diagnosis and the control group consisted of
participants without a cancer diagnosis. In Sample 1, participants in the cancer group
were recruited from voluntary cancer support groups in Penang, and participants in
the control group were recruited from Universiti Sains Malaysia (USM) and citizens
in Penang. In Sample 2, participants in the cancer and control groups, respectively,
were recruited from the Cancer Rehabilitation Association, the Red Cross Society of
China Yunnan Branch and citizens in Kunming, Yunnan, China. In Sample 1
(N1=287), a total of 133 responses in the cancer group and 142 responses in the
control group were included in the final analyses.
