In this survey carried out over a 4-year period we explored the changes perceived in the locus of control (LOC) of 58 nursing students enrolled in a baccalaureate nursing education program with an integrated problem-based learning curriculum. The results suggested that there was a statistically significant difference in LOC between the first and second years. A significant difference was found in the mean scores of the students according to year in personal control, fatalism, and belief in an unfair world. But, when analyzed further, there were no significant differences according to year in personal control and belief in an unfair world. However, a statistically significant difference was found in fatalism between the first-and third-year students. Implications for nursing training programs and curriculum development are discussed.Keywords: locus of control, nursing students, problem-based learning. (Dag, 1997). Researchers have described two potential sources of LOC for individuals: intemal and extemal. Rotter (1966) theorized that individuals with an intemal LOC beüeve that they have control over things that happen to them whüe those with an extemal LOC beüeve that outside forces influence them. Individuals with an intemal LOC have been characterized as active, effective, talented in problem solving, highly motivated, self-confident, and successful in personal ufe, school, and work.
