The Client's and Therapist's Vocal Qualities in CBT and PE-EFT for Depression
Bibliographic record
Abstract
The psychotherapy client’s vocal quality indicates the quality of and shifts in the client’s engagement in treatment. In contrast, the therapist’s vocal quality is a treatment intervention, either facilitating or hindering the client’s progress. The Client Vocal Quality (CVQ) and Therapist Vocal Quality (TVQ) measures (Rice & Kerr, 1986) were applied to responses in the middle 20 minutes of low and high change sessions for 61 clients who received either cognitive behavioural therapy (CBT) or process-experiential emotion focused therapy (PE-EFT) for depression (Watson, Gordon, Stermac, Kalogerakos, & Steckley, 2003). Sessions were selected using the Client Task Specific Change Measure-Revised (CTSC-R; Watson, Greenberg, Rice, & Gordon, 1996). Outcome measures included the Beck Depression Inventory, Dysfunctional Attitude Scale, Global Severity Index of the Symptom Checklist-90-Revised, Inventory of Interpersonal Problems, Problem-Focused Style of Coping Scale, and Rosenberg Self-Esteem Scale. The CVQ categories differentiated between treatment types, with PE-EFT clients expressing a significantly higher proportion of Emotional vocal quality and CBT clients expressing a significantly higher proportion of Externalizing vocal quality. There was no difference between the treatment types for Focused or Limited vocal quality. The CVQ categories predicted outcome. This relationship was particularly evident in the session in which clients first reported moderate to high change on the CTSC-R. The combination of Emotional and Focused categories was a stronger predictor than either category alone. In contrast, a higher proportion of Externalizing vocal quality predicted worse scores. In terms of Therapist Vocal Style, PE-EFT therapists spoke predominantly in the Softened-Irregular Vocal Style, while CBT therapists spoke predominantly in the Natural-Definite Vocal Style. Therapists’ use of a Softened-Irregular Vocal Style, compared with a Natural-Definite Vocal Style, was associated with the client’s report, at the end of therapy, that he/she felt less easily exploited by others and had a greater ability to assert interpersonal boundaries without fear of offending others. Limitations of the study are discussed.

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.
