Shared decision making and associated factors among patients with psychotic disorders: a cross-sectional study

Shared decision making is a process where patients and clinicians collaborate to make treatment choices based on the patients' preferences and best available evidence. The implementation of shared decision making remains limited for patients with psychotic disorders despite being recommended at policy level, being advocated as ethical right and wanted by the patient's. A barrier to implementation that is often mentioned is reduced decision-making capacity among patients. The challenges of implementing shared decision making highlights a need for more knowledge on shared decision making for these patients. Moreover, the association between patient-related characteristics and shared decision making is unclear, and further research have been suggested. More knowledge of factors associated with involvement in shared decision making can enhance understanding and help to empower patients in the decision-making process. The current study examined the extent of reported shared decision making among patients with a psychotic disorder in mental health care and factors associated with shared decision making.

This study included 305 participants with a psychotic disorder from 39 clinical inpatient and outpatient sites across Norway. Shared decision making was assessed using the CollaboRATE survey. A linear mixed model was estimated to assess characteristics associated with shared decision making scores.

The CollaboRATE mean score was 6.3 (ranging from 0 to 9), the top score was 14.1% and increased global satisfaction with services was significantly associated with a higher level of shared decision making (regression coefficient 0.27, 95% confidence interval (0.23; 0.32), p < 0.001).

The low top score shows that few patients felt that they received the highest possible quality of shared decision making, indicating that many patients found room for improvement. This suggests that services for patients with psychotic disorders should be designed to give them a greater role in decision making. Shared decision making might play a key role in mental health care, ensuring that patients with psychotic disorders are satisfied with the services provided.
