Decisions in adolescent and young-adult outpatient psychiatry are rarely governed by symptom change alone. A treatment may produce substantial clinical improvement yet be difficult to continue, while a highly acceptable treatment may yield modest change. Conventional single-endpoint comparisons do not show whether a service preference remains defensible when clinicians, patients, and families assign different importance to improvement, continuation, and tolerability. This study asked whether the comparative value of metacognitive-interpersonal-therapy (MIT)-integrated psychotherapy remains positive across plausible priorities for clinical change, treatment continuation, and event-free care. Group summaries from 57 psychotherapy recipients aged 13–23 years were combined with treatment-continuation and adverse-event counts. A Bayesian Joint-Care Priority Surface was developed. Directional difference-in-change distributions were estimated for functioning, psychiatric symptoms, and clinician-rated severity while varying the unknown within-person correlation. Jeffreys-prior beta–binomial models estimated continuation and event-free probabilities. Each posterior draw was converted to a bounded, scale-independent advantage, and 861 weight combinations were evaluated across the three decision domains. Two hundred thousand draws were used for the principal analysis. Prior concentration and within-person correlation were varied in computational stress tests. Directional advantages favored MIT-integrated care for functioning (mean difference-in-change 0.660, 95% credible interval [CrI] 0.092 to 1.227; probability of benefit 0.989), psychiatric symptoms (10.030, 95% CrI 4.127 to 15.965; probability 1.000), and clinician-rated severity (0.280, 95% CrI \(-0.276\) to 0.838; probability 0.836). Continuation favored MIT-integrated care probabilistically (risk difference 0.106, 95% CrI \(-0.107\) to 0.291; probability 0.855), whereas event-free care was practically balanced (risk difference \(-0.021\), 95% CrI \(-0.241\) to 0.167; probability 0.440). Under equal domain weights, the joint score was positive in 94.7% of draws. At least 80% support occurred in 75.3% of the weight grid. Stress-test probabilities ranged from 0.859 to 0.953. The paper’s research question is answered affirmatively but conditionally: MIT-integrated psychotherapy retains positive comparative value for most reasonable priority combinations because the symptom and functioning signals outweigh neutral tolerability evidence. A preference cannot be justified when near-exclusive weight is placed on event-free care. The result supports a monitored service preference rather than an unconditional claim of therapeutic superiority.
