This study used 8 vignettes to investigate 331 school psychology graduate students' beliefs concerning the desirability and ethicalness of origin of a dissertation idea and authorship credit of an article based on the dissertation. The vignettes varied according to who originated the dissertation idea (graduate student or advisor), who wrote an article based on the dissertation (graduate student or advisor), and authorship credit for that article (graduate student or advisor listed as either sole or principal author). Responses to the vignettes by respondents indicated that they believed it is more desirable and ethical for a dissertation design to be the student's rather than the advisor's idea. Respondents also believed that it is more desirable and ethical for the student to be either sole or first author of an article based on the dissertation, regardless of who (student or advisor) originated the dissertation idea or wrote the resulting paper.
