Therapist Adherence to Two Treatments for Adolescent Suicide Risk: Association to Outcomes and Role of Therapeutic Alliance

In psychotherapy research, adherence refers to the extent to which therapists deliver a treatment as intended. This study examined whether therapist adherence to two different manualized treatments was associated with improved client outcomes and whether the association was moderated by therapeutic alliance. The study sample included 320 video recordings of therapy sessions from 118 cases in a randomized controlled trial (RCT) comparing attachment‐based family therapy (ABFT) with family‐enhanced nondirective supportive therapy (FE‐NST). Recordings were selected from early, middle, and late stages of treatment. The adherence measure consisted of 24 items representing essential therapist interventions from both treatments. Trained raters coded tapes from both therapies. Adolescent self‐report of alliance was measured at session 4. Adherence to ABFT was associated with a significant increase in family cohesion at mid‐treatment but not at posttreatment. Adherence to FE‐NST was significantly associated with an increase in suicide ideation posttreatment. Using therapeutic alliance as a moderator, adherence to ABFT was significantly associated with a reduction in suicide ideation, family conflict, and higher client satisfaction posttreatment. Alliance did not positively affect the association of FE‐NST adherence to outcomes. Findings suggest that adherence to ABFT interventions may be better linked to treatment outcomes when adolescents feel a strong alliance with their therapist. Implications for future research and therapist training are explored. Resumen En la investigación sobre psicoterapia, la adhesión se refiere al grado en el cual los terapeutas brindan un tratamiento según lo previsto. Este estudio analizó si la adhesión del terapeuta a dos tratamientos estandarizados diferentes estuvo asociada con mejores resultados en los pacientes y si la asociación estuvo moderada por la alianza terapéutica. La muestra del estudio incluyó 320 videograbaciones de sesiones de terapia de 118 casos en un ensayo aleatorizado controlado donde se comparó la terapia familiar basada en el apego (TFBA) con la terapia de apoyo no directiva optimizada por la familia (TAND‐OF). Se eligieron grabaciones de las etapas iniciales, intermedias y finales del tratamiento. El instrumento de medición de la adhesión consistió en 24 ítems que representaban intervenciones esenciales del terapeuta de ambos tratamientos. Un grupo de calificadores capacitados codificaron las grabaciones de amba
