The objectives of the study are (a) to understand the therapeutic interventions and attitudes that either facilitate or hinder the resolution of alliance ruptures and (b) to develop a model for repairing these ruptures within this particular treatment approach. To accomplish this, a task analysis of a previously developed rational model of resolving alliance ruptures was conducted using 16 sessions from short-term psychodynamic psychotherapy with depressed adolescents. The analysis supported some stages of the hypothesized rational model while revealing the need for revisions. As a result, the study developed a rational-empirical model that includes flexible strategies that therapists can use to repair alliance ruptures. This model emphasizes the significance of a collaborative, open, and empathetic approach to resolving ruptures. In contrast, rigid, defensive, or invalidating therapist attitudes can hinder the resolution process. The evidence-based model developed from the study can provide valuable guidance to psychodynamic psychotherapists working with young people, offering insights on how to approach ruptures and employ effective strategies to promote their resolution.

A newly developed performance-based measure of MCO capacities exists (MCO-performance task [MCO-PT]) in which therapists respond to video-based vignettes of clients sharing culturally relevant information in therapy. The MCO-PT provides scores related to the three aspects of MCO: cultural humility (i.e., adoption of a nonsuperior and other-oriented stance toward clients), cultural opportunities (i.e., seizing or making moments in session to ask about clients' cultural identities), and cultural comfort (i.e., therapists' comfort in cultural conversations). Although a promising measure, the MCO-PT relies on labor-intensive human coding. The present study evaluated the ability to automate the scoring of the MCO-PT transcripts using modern machine learning and natural language processing methods. We included a sample of 100 participants (<i>n</i> = 613 MCO-PT responses). Results indicated that machine learning models were able to achieve near-human reliability on the average across all domains (Spearman's ρ = .75, <i>p</i> < .0001) and opportunity (ρ = .81, <i>p</i> < .0001). Performance was less robust for cultural humility (ρ = .46, <i>p</i> < .001) and was poorest for cultural comfort (ρ = .41, <i>p</i> < .001). This suggests that we may be on the cusp of being able to develop machine learning-based training paradigms that could allow therapists opportunities for feedback and deliberate practice of some key therapist behaviors, including aspects of MCO.
