Further psychobiographical research is needed to establish a professional and well- acknowledged research methodology for psychobiographical research. Different theoretical and methodological paradigms need to be combined in psychobiographical research and critically reviewed. In this study, positive psychology theories were combined with hermeneutical methodological concepts. However, more research on the research methodology in psychobiographical research, on sampling, quality criteria and markers of “good” psychobiographies are needed to establish a strong psychobiographical and methodological research culture that might draw interest from mainstream psychology. It would then also be important to explore the interrelationship of quality criteria in psychobiographical research and research ethics in terms of this psychobiographical single-case study.
Future research in psychobiographies should take mixed method approaches into account and combine quantitative methods and statistical analysis with qualitative methods and forms of analysis. At the same time, psychobiographical work could also use multiple qualitative methods of analysis, such as content analysis, thematic analysis or narrative analysis to explore the impact of the method of analysis used in the study. Research methods, particularly focusing on writers and artists, should include not only common psychological theories and methodologies, but also inter?disciplinary ones. In the analysis of biographies and the creative works of writers, for example, linguistic analysis might be helpful to explore the extraordinary individual in further depth. Psychobiographies, as studies across the life span, should be open to include methodologies and methods across disciplines that might contribute to a more holistic view on an individual and his/her single life. In summary, a huge variety of research methods across disciplines should be used, explored and tested in psychobiographcial research to guarantee a triangulation of methodology.
