The genogram is not only a practical tool, but also a qualitative research method. Anyone wishing to research their own counselling practice—whether for a master's thesis, a doctoral dissertation, or an evaluation study—requires a different methodological discipline than in a counselling session. This lesson clarifies what makes the genogram a research method, how it is embedded in German-language biographical research, and which quality criteria must be observed.

Practice Genogram and Research Genogram

In the clinical setting, the genogram is a co-constructed tool between client and practitioner, evolving through conversation, changing over time, and serving the purpose of helping the client understand their family situation. It does not need to be "objective", reproducible, or intersubjectively verifiable. In the research setting, this changes. The research genogram is a data collection instrument whose data should be accessible to other researchers for verification. It must be collected systematically, documented, and analysed in a transparent manner. Statements that are heuristically helpful in the therapeutic setting ("This might have something to do with your grandmother") are insufficient in research—here, methodological discipline is required: Which statement is based on which source, which interpretation on which theory?

This shift does not mean that the research genogram is "objective" in a positivist sense. Since its methodological consolidation in the 1980s, qualitative social research has understood itself as a reconstructive science—it does not seek "the truth of the family", but rather the structural logic of a biographical constellation, as it can be reconstructed from the available material. This is demanding: It requires both closeness to the case (careful observation, avoidance of premature generalisations) and theoretical distance (the ability to subsume the concrete under more general concepts). In this research paradigm, the genogram is a structuring tool that makes biographical complexity visible and manageable.

Embedding in German-Language Biographical Research

German-language biographical research is methodologically sophisticated and provides the natural framework for genogram-based research. Gabriele Rosenthal (Göttingen) has shaped the field with her approach to biographical case reconstruction: narrated life history and experienced life history are methodologically distinguished, and their difference becomes the analytical starting point. Fritz Schütze developed the narrative interview as a data collection method—a specific form of interviewing aimed at spontaneous storytelling, which, through its formal properties (requirements for detail, narrative closure, and condensation), allows for systematic analysis. Wolfram Fischer-Rosenthal combined these strands into the biographical-narrative method, which is widely used in German-language social and educational research.

Bruno Hildenbrand (Jena) is one of the few who has explicitly developed the genogram as a research method—both in his book "Einführung in die Genogrammarbeit" (Carl-Auer) and in numerous contributions to social science case reconstruction. Hildenbrand links genogram work with Oevermann's objective hermeneutics: The genogram provides structural data (who is related to whom, in what order, with which biographical key data), which can be used as a structural framework in sequential analysis. A biographical sequence analysis that does not include the genogram risks underestimating or misreading the biographical meanings of a family situation.

Triangulation: Genogram, Interview, Documents

The research genogram becomes methodologically productive primarily in triangulation with other data collection methods—a research logic that Uwe Flick has systematically developed as a methodological principle of qualitative research. The typical triangulation constellation in biographical research consists of three sources: firstly, the genogram interview, in which the research participant and the researcher jointly draw and comment on the family structure; secondly, one or more biographical-narrative interviews in the sense of Schütze, which elicit the narrated life story in its own logic; thirdly, where available, documents (family photos, family trees, diaries, official documents), which anchor or contradict the narrative.

The analytical strength of triangulation does not lie in confirmation—as if three sources saying the same thing would "guarantee the truth"—but in the productive handling of differences. If the genogram interview sketches a different family constellation than the narrative interview or the documents, this is not a methodological problem but an analytical datum: What is the significance of the difference? What does it reveal about self-presentation, family narrative, or zones of silence? Here, the genogram is especially valuable, as its graphic-structuring form makes omissions and additions visible that can be easily missed in the flow of an interview.

Methods of Analysis: Sequence Analysis and Case Reconstruction

The analysis of biographical data involving a genogram typically follows one of two methodological traditions. Sequence analysis (Oevermann, Hildenbrand) is based on the principle that biographical structures can be reconstructed from the sequence of concrete actions and utterances. In sequence analysis, a datum (a genogram statement, an interview passage) is read step by step; at each point, all theoretically possible continuations are considered, the actual continuation is contrasted with the possibilities, and the structural logic of the case is inferred. This method is methodologically demanding, time-intensive, and yields dense case reconstructions.

The documentary method (Bohnsack) and content analysis (Mayring) are alternative approaches with different epistemological assumptions—in practice, they are often combined in research projects. Anyone planning genogram-based research for a master's or doctoral thesis should choose a methodologically consistent approach and apply it transparently: What steps were taken, according to which criteria were categories formed, which theories were used for interpretation? This transparency is a prerequisite for the quality criteria of qualitative research.

Quality Criteria: Intersubjective Traceability Instead of Reliability

The classical quality criteria of quantitative research—objectivity, reliability, validity—do not fit qualitative research seamlessly. Ines Steinke's proposal to assess qualitative research according to the criteria of intersubjective traceability, indication of the research process, empirical grounding, limitation, coherence, relevance, and reflexive subjectivity has become widely accepted in German-language research methodology. For genogram-based research, two of these are particularly central: Intersubjective traceability requires that other researchers can follow the analysis process—all steps, from data collection to interpretation, must be documented. Reflexive subjectivity requires that the researcher incorporates their own position, assumptions, and resonances with the material into the analysis.

For genogram-based studies, this means: The genogram collected is not merely "data", but becomes the subject of reflective presentation in the research report itself. How was it collected? Who said what, in what order? What omissions were noticed? What changes occurred over time? What personal resonances did the researcher experience—and how were these handled? This reflexivity is not a therapeutic add-on, but a methodological standard in qualitative research.

Anonymisation, Ethics, Publication Practice

A specific methodological and ethical issue concerns publication. Family constellations are highly identifiable—if a study describes a family with five siblings, two school changes, a fatal traffic accident, and a conversion to Buddhism, this is a case that family members will immediately recognise, even if all names have been changed. Anonymisation in the narrow sense (replacing names) is therefore insufficient. Careful qualitative research employs techniques of obfuscation—changing professions, shifting places of birth, composing cases from several families, where the study design permits.

The ethical agreement with research participants must cover these practices. Informed consent should include: What data will be collected, how will it be analysed, how will it be obfuscated, how will it be published, what rights does the person have to withdraw their data? For genogram research in institutional contexts (clients in practices, patients in clinics), ethics committees are usually responsible—master's students should check early on what requirements their university sets.

Practice Vignette

A master's student in social work is researching the professional biographies of social workers with a migration background—how do family migration experiences and professional identity intersect? She chooses a three-part design: a genogram interview, a subsequent biographical-narrative interview, and a brief written self-documentation. The genogram interview provides the structure (which generations are involved, which migration movements, which professions in the family), the narrative interview provides the meaning (how is all this narrated, what is remembered in what order), and the self-documentation provides a position of distance (what does the person say when they later reflect on the material).

The analysis reveals something that would never have become so clear in counselling practice: Social workers with a migration biography often use their own family history as an implicit method in their client work—without this being addressed in training or reflected upon in supervision. This is a research finding worthy of publication and has practical consequences for training. The student invested the methodological discipline required—and the result reflects that investment.

State of Research & Discussion

Genogram-based qualitative research is an established, though often methodologically under-discussed, practice in German-speaking countries. Hildenbrand's school is the most elaborated tradition; in addition, there are numerous applications in nursing science, family research, social work research, and educational research. Internationally, the method is less widespread—in the Anglo-American tradition, Grounded Theory predominates, which employs different data collection logics and theoretical approaches. This is partly because German-language biographical research (Rosenthal, Schütze, Fischer-Rosenthal) constitutes its own school with its own methodology, which is less widely received internationally.

A critical discussion concerns the relationship between practice reflection and research. Practitioner self-reflection on one's own practice is not methodologically the same as research, even if similar tools are used. Practitioners wishing to use genogram material from their own client work for a research question face a range of methodological and ethical challenges: Can data collected in therapeutic confidence be repurposed for research—and if so, under what conditions? The simplest and methodologically cleanest solution is to separate practice and research: Those who wish to conduct research should collect their own data in an explicit research setting, with its own consent, its own ethics review, and its own analysis. What is said in the therapy session belongs in the therapy session—not in the dissertation.
