“…More useful for the evaluation of ethics training are those designs where one type of training is evaluated through a pretest-posttest design (often with experimental and control group). Several studies show a positive effect of the ethics training on participants' moral sensitivity (Wu, 2003;Myyry & Helkama, 2002;Gautschi & Jones, 1998), moral reasoning (O'Leary, 2009;Loe & Weeks, 2000;Glenn, 1992;Schlaefi, Rest, & Thoma, 1985), moral values (Wu, 2003;Weber & Glyptis, 2000), cognitive flexibility (Carlson & Burke, 1998) and autonomous problem solving (Kavathatzopoulos, 1994). However, other studies using this same design could not find any effect on participants' ethical orientation (DeMoss & McCann, 1997) and moral attitudes (Wynd & Mager, 1989).…”
