The association between patient-therapist MATRIX congruence and treatment outcome.

Objective: The present study aimed to examine the association between patient-therapist micro-level congruence/incongruence ratio and psychotherapeutic outcome. Method: Nine good- and nine poor-outcome psychodynamic treatments (segregated by comparing pre- and post-treatment BDI-II) were analyzed (N = 18) moment by moment using the MATRIX (total number of MATRIX codes analyzed = 11,125). MATRIX congruence was defined as similar adjacent MATRIX codes. Results: the congruence/incongruence ratio tended to increase as the treatment progressed only in good-outcome treatments. Conclusion: Progression of MATRIX codes' congruence/incongruence ratio is associated with good outcome of psychotherapy.
