Univariate analyses identified that the groups with less psychological distress were male(ηp2=0.016), married (ηp2=0.006), and had better performance status (ηp2=0.007). The most widely used coping strategies were positive attitude and cognitive avoidance. A positive relationship was found between uncertainty, coping strategies,and psychological distress (pConclusion: Most people with unresectable advanced cancer experience psychological distress in the face of uncertainty.
