Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q2 i? When complementarity was examined across the entire therapeutic relationship, successful and unsuccessful outcome groups showed no significant difference, though successful therapists trended somewhat lower. → Dietzel 1974

q2 · i? · associational · r1
Behavioral analysis of 120 rated tape segments from 20 late-adolescent clients (10 successful, 10 unsuccessful outcome by clinician MMPI ratings) compared Complementarity Index values across all sessions. The study reports "no significant differences (t = 1.309, p > .05)" between groups, with only a tendency toward lower complementarity in successful therapists.
"When the level of therapist complementarity during the entire therapeutic relationship was examined, there were no significant differences (t = 1.309, p > .05) between the successful and unsuccessful outcome groups."

Related Claims¶
- Early-stage therapist complementarity does not differ by outcome group, and the predicted later-stage advantage for successful dyads was not supported — related
- During the early stage of therapy, more severely maladjusted clients elicit higher levels of therapist complementarity — related
- Observed interaction frequencies support the Interaction Matrix cell weightings, with the most interactions in the highest-weighted cells — related
- During the middle stage of therapy, successful therapists respond at a significantly lower level of complementarity than unsuccessful therapists — reports the opposite
- Therapy relationships do not show a transition from relational incongruence to congruence across sessions — related
- Response redundancy (relational congruence) is not related to working alliance ratings — related
- Quality of the therapeutic relationship and counseling effectiveness are not correlated with each other, though both correlate with therapist experience — related
