Here is an excerpt:
Although several different shared decision-making models exist (for a review see Lin & Fagerlin, 2014), one useful approach conceptualizes shared decision-making as consisting of three phases
(Elwyn et al., 2012): choice talk, option talk, and decision talk. Choice talk involves communicating
to patients that there is a decision to make and that they can be involved in this decision to the extent
that they are comfortable. Option talk consists of sharing accurate and comprehensive information
about treatment options. Ideally, this involves the use of a decision aid, which is an educational tool
such as a website, brochure, or video designed to help patients understand and compare various
options (for a review, see Stacey et al., 2017). The third and final step, decision talk, consists of an
exploration of the patient’s preferences and what matters most to him or her. The process of shared
decision-making is intended to help the patient develop informed preferences, and ultimately arrive
at the decision that is best for him or her. Importantly, patients with the same clinical condition may arrive at very different treatment decisions on the basis of unique values and preferences.
Shared decision-making has been evaluated most often among patients facing care decisions for chronic medical conditions, especially cancer. In medical patients, shared decision-making has been linked with greater confidence in the treatment decision, improved satisfaction with decision-making and with treatment, greater self-efficacy, and increased trust in the provider (Joosten et al., 2008; Shay & Lafata, 2015). In mental health, shared decision-making has been most often evaluated in the context of depression, yielding mixed results on both satisfaction and treatment outcomes (Duncan, Best, & Hagen, 2010). Fewer studies have evaluated the effectiveness of shared decision-making for other mental health conditions such as PTSD.
