not-yet-known not-yet-known not-yet-known unknown Why Deliberate Practice and the Sentio Supervision Model There are several areas where the Sentio Supervision Model (SSM) and its use of DP principles address common limitations of TS. Implementing DP to any field constitutes three main elements: the creation of personalized behavioral learning objectives, repeated behavioral skill rehearsals, and the delivery of expert feedback that guides and enhances further practice (Ericsson, 2018, 2003). These DP training principles in general, and the SSM in particular, are distinctive from our field’s traditional supervision methods in several ways: DP utilizes skills training to emphasize procedural learning. While TS prioritizes conceptual learning (“learning by reflecting”), DP methods promote procedural learning (“learning by doing”). This means jointly identifying at a set of concrete microskills that can be repeatedly practiced and refined to address a supervisee’s supervisee’s identified challenges. The SSM uses therapy recordings to aid in providing performance feedback and concrete micro-skills training. DP aims to create an environment that looks as much like the actual performance (or, for our purposes, the clinical encounter between client and therapist) and video provides this high definition picture (Ericsson, 2018, 2003). Importantly, the review of video recordings of the therapy session during supervision provides a clearer picture of the supervisee’s performance than their self-reporting (Haggerty & Hilsenroth, 2011). Through the use of outcome measures, the SSM and DP emphasize clear results that can provide feedback to therapists on their most challenging clients. Outcome measures are a reliable way to catch client deterioration (Lambert, 2010; Lambert et al., 2018). It is in the areas where we are struggling the most, where we can most benefit from learning that is individually catered to our challenges and where we require repeated practice with well timed expert feedback (Ericsson, 2018, 2003). In addition, the use of outcome measures allows for therapists to have direct feedback from their clients as another way to answer the tricky question of what is good therapy (Miller et al., 2020).
