Background: To measure and compare the extent to which shared a decision making (SDM) process is implemented both in psychiatric outpatient clinical encounters and in the primary care setting from the patient's perspective.

Methods: A total of 1,477 patients recruited from the Canary Islands Health Service mental health and primary care departments were invited to complete the nine-item Shared Decision Making Questionnaire (SDM-Q-9) immediately after their consultation. MANCOVA, Student's t-test, and Pearson correlations were used to assess the relationship and differences between SDM-Q-9 scores in patient samples.

Results: No differences were found in SDM-Q-9 total scores between the two patient samples, but there were relevant differences when item by item analysis was applied; differences were observed according to the different steps of the SDM process. SDM is present to a very limited extent in the routine psychiatric setting compared to primary care. Patients' age, education, type of appointment, and treatment decision all play a specific role in predicting SDM.

Conclusion: The study provides evidence that SDM is a complex process that needs to be analyzed according to its different steps. SDM patterns were different in the primary care and psychiatric outpatient care settings and reflect quite a different perspective of the decision making process.

Keywords: SDM-Q-9; primary care patients; psychiatric outpatients; shared decision making.
