Outcome expectancy. In general, to decrease anxiety, more attention should be paid to positive outcome expectancies of patients. It is proven that positive outcome expectancies reduce state anxiety (Nijkamp et al., 2004). Different expectations before surgery are a reason why some patients are more satisfied than others. It has been proposed that satisfaction is also influenced by patients‟ expectations of treatment quality (Strasser, Schweikhart, Welch, & Burge, 1995). Moreover, Jackson, Chamberlin, and Kroenke (2001) found that unmet expectations significantly decreased patient satisfaction.
