« In addition, further studies should be conducted to characterize ergodic subgroups using baseline data. This allows patients to be assigned to the most likely change profiles, particularly in a clinical context, enabling treatment planning even before therapy begins. »

« Future studies could expand this line of research by linking ergodicity-informed subgroups to treatment response trajectories, dropout risk, or session-level process measures (e.g., alliance ruptures, sudden gains). »

« identifying structurally ergodic subgroups offers a principled way to derive clinically homogeneous reference groups. Our results lay the groundwork for such tools by demonstrating that subgroups differ not only in symptom severity, but in how they change during treatment. »

« Regarding the clinical implications of our findings, we suggest using the community structure of ergodic subgroups as a relatively robust source of information on change dynamics because it should be easier to assign interventions to groups of symptoms. »

« In this light, the identified subgroups may be understood as distinct “process profiles” that could inform more tailored, process-focused interventions—a notion that resonates with the core aim of process-based models to bridge nomothetic evidence and idiographic practice. »

« These subgroup-level regularities may reflect common underlying change processes, aligning with the PBT principle of deriving generalizable patterns only insofar as they inform individual case conceptualization »

« Our information-theoretic modeling revealed the emergence of structurally ergodic subgroups, indicating that, despite overall heterogeneity in the sample, distinct clusters of patients exhibited stable and similar symptom interrelations over time. »
