Grounded Theory in Psychiatric Research: Theoretical Models for Evidence-Based Practice

• Applicant: Dr. Theresa Halms
• Subject Area: Clinical Psychiatry, Psychotherapy, Child and Adolescent Psychiatry
• Term: since 2025
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 569941110

The proposed research project focuses on the development of theory-based models to explain decision-making processes in psychiatric care, specifically during the discontinuation of psychotropic medication (deprescribing), the termination of psychotherapy, and the implementation of the German S3 schizophrenia guideline. These processes involve balancing clinical recommendations, individual experiences, therapeutic relationships, and structural conditions. However, they are still insufficiently addressed in empirical research and are only partially considered in existing clinical guidelines. Using previously collected qualitative data from patients, relatives, and practitioners, I will apply Grounded Theory methodology to systematically reconstruct the structure, logic, and dynamics of these decisions. My aim is not only to describe the processes but to develop explanatory models that integrate different actor perspectives and contextual factors. These models will provide a conceptual basis for improving decision-making and strengthening evidence-based psychiatric care. The project also aims to significantly advance my methodological expertise in qualitative research, with a particular focus on Grounded Theory methodology. Over the course of the research stay, I will undertake an intensive training programme in Grounded Theory at the Institute of Education (IoE), University College London (UCL), under the supervision of Professor William Gibson. As a leading expert in qualitative methods, Professor Gibson offers extensive experience in both applying and teaching Grounded Theory. The opportunity to collaborate with him, attend his courses, and receive continuous feedback on my analytic work represents a key part of my qualification goals. In addition, I will benefit from a newly forming interdisciplinary network within the department, which connects researchers working on healthcare-related topics and creates space for valuable methodological exchange. The work programme consists of three phases: (1) in-depth training in Grounded Theory methodology; (2) theory-building analysis of qualitative interview data; and (3) dissemination of findings through publications and conferences. The data corpus includes interviews with patients, relatives, and healthcare providers. Using this existing material allows for immediate analytical focus and efficient use of time. By addressing key challenges in psychiatric care and developing grounded, practice-oriented models, my project contributes to international health services research. At the same time, it supports my continued academic development through advanced methodological training, international networking, and the strengthening of my independent research profile. In the long term, this research stay is a central step in qualifying for a professorship with a focus on qualitative methods in psychiatric and mental health services research.
