The Observer OPTIONMCC  is developed to observe participation in decision making for (older) patients with multiple chronic conditions. The Observer OPTIONMCC is based on the Dynamic model for shared decision making in frail older patients (Van de Pol et al., 2016). It connects to Goal-Based shared decision making, by observing Goal talk as a separate, first item of the scale.

The Observer OPTIONMCC not only observes the role of the clinician in shared decision making, but also the participation of patients in this process. Since informal caregivers are often involved in the care for these patients, they also participate in the decision making process. This is called ‘triadic’ decision making, involving the clinician, patient and informal caregiver.
