Research findings support the presence of psycho-social challenges for third culture kids (TCKs) given their lifestyle of high mobility and the acculturative stress of repatriation.  I structured this study as a self-experimentation hermeneutic single-case efficacy design (auto-HSCED).  Through HSCED I investigated the efficacy of lifespan integration (LI) therapy in addressing issues with self-structure and autobiographical narrative fragmentation.  I proposed the use of an Eriksonian-based ego identity fragmentation model as an explanatory framework for conceptualizing these long-term self-identity issues among TCKs.  Acting as both the study participant and primary investigator, I sought to answer: Can LI be efficacious in addressing ego identity fragmentation in an adult TCK?  Initial outcomes did not meet HSCED standards for significant client change due to LI therapy, however, I noted significant discrepancies in the results which led to a secondary examination of the findings.  My investigation revealed evidence of oppressive data interpretation and analysis processes that I corrected through a metasynthetic remediation process.  This re-contextualization of the initial findings allowed me to re-interpret them within a broader intersectional framework.  I concluded by arguing for outcomes having met HSCED’s threshold for significance and for demonstrating clear and compelling evidence of LI efficacy in producing client ego identity change.  Finally, I offered a unique perspective on the therapeutic process through the inclusion of enhanced reflexivity processes in which I invite the reader into my personal therapeutic and academic journey of ego identity integration.
