Genetics in the medical and psychosocial practice: on the role of value hierarchies in counselling

What value structure underlies shared decision making? A qualitative synthesis of models of shared decision making

OBJECTIVE

To construct the underlying value structure of shared decision making (SDM) models.

METHOD

We included previously identified SDM models (n = 40) and 15 additional ones. Using a thematic analysis, we coded the data using Schwartz's value theory to define values in SDM and to investigate value relations.

RESULTS

We identified and defined eight values and developed three themes based on their relations: shared control, a safe and supportive environment, and decisions tailored to patients. We constructed a value structure based on the value relations and themes: the interplay of healthcare professionals' (HCPs) and patients' skills [Achievement], support for a patient [Benevolence], and a good relationship between HCP and patient [Security] all facilitate patients' autonomy [Self-Direction]. These values enable a more balanced relationship between HCP and patient and tailored decision making [Universalism].

CONCLUSION

SDM can be realized by an interplay of values. The values Benevolence and Security deserve more explicit attention, and may especially increase vulnerable patients' Self-Direction.

PRACTICE IMPLICATIONS

This value structure enables a comparison of values underlying SDM with those of specific populations, facilitating the incorporation of patients' values into treatment decision making. It may also inform the development of SDM measures, interventions, education programs, and HCPs when practicing.
