%X In this paper, we describe how the Harthill Leadership Development Profile(LDP), a language-based instrument has evolved from Jane Loevinger¡¯s WashingtonUniversity Sentence Completion Test (WUSCT), and has been redesigned to assess andoffer feedback about adults¡¯ action logics in work or educational settings, in the contextof Developmental Action Inquiry (DAI) theory, practice, and method (Torbert, 1972,1976, 1987, 1991; Torbert & Associates, 2004).Next, we challenge a recent critique of the LDP as a soft measure unsupported bypublished, quantitative psychometric reliability and validity studies (Stein & Heikkinen,2009) and present both previously unpublished and previously published-but-notaggregatedstudies illustrating Harthill LDP as a well-calibrated measure of adult egodevelopment.Because the DAI approach to social inquiry and social practice invites us all tointerweave first-, second-, and third-person inquiry and everyday action, the validitystudies reported tend to concern field-based experiments seeking to generatedevelopmentally transforming change in adults, including the researchers and/orinterventionists, as well as in the organizations in which they participate.In our conclusion, we briefly consider what a social science and a social practice basedon the developmentally late action-logics will look like, once social science is recognizedas embracing, not just 3rd-person empirical positivist research ¡°on¡± subjects, but also 1st-,2nd-, and 3rd-person research and action with co-participants in live settings.
