Therapeutic Mentalization in Group Therapy: Development and Preliminary Validation of a Measure of Experienced Mentalization
Bibliographic record
Abstract
Our paper reports on the development and psychometric properties of the Therapeutic Mentalization Scale for Group Therapy (TMS-GT). The TMS-GT is an 11-item self-report measure designed to assess individuals’ experiences of having been mentalized in group therapy. Two combined samples of adults (n = 157; Mage = 28.4, SD = 12.1) participating in separate outpatient group psychotherapy treatments completed the TMS-GT posttreatment, with a subsample (n = 87) completing the TMS-GT again 3 months later and the other subsample (n = 70) completing measures of group psychotherapy processes and psychiatric symptoms. Multilevel exploratory factor analysis identified the two-factor structure of the TMS-GT, reflecting two dimensions of the experience of having been mentalized: mentalized attunement and mentalized continuity. The two subscales demonstrated adequate internal consistency and temporal stability. Moreover, additional psychometric findings provided further support for the validity of the TMS-GT. Overall, preliminary analyses suggest that the TMS-GT appears to be a reliable and valid measure of the experience of being mentalized among adults participating in outpatient group therapy.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
