The general participation preference at baseline is measured with the two decision-making items from the Problem-Solving Decision-Making Scale [ 23].
Preference for decision-making was measured with the two decision-making items from the Problem-Solving Decision-Making Scale (PSDM) by Deber et al (1996).
Patients in this study rated their experience using the PtDA favorably as indicated in both the preparation for decision making items and their qualitative feedback.
The names assigned the components were derived from the content of the items with highest loadings in each component [ 65] and are as follows: Direct Clinical Practice (19 items), Professional Development (5 items), Ethical Decision-Making (11 items), Clinical Leadership (6 items), Cooperation and Consultation (6 items), and Critical Thinking (4 items).
6. Participation in decision-making (4 items, e.g. I have opportunities to make independent decisions in my work, α = 0.741); 7. Sense of community (4 items, e.g. I trust the expertise of my colleagues, α = 0.732).
The author also identifies a number of informal decision-making principles: Items that are strategically significant and touch on the firm's core values should go to the board.
These scores are derived from four MDS variables – two cognitive items (short-term memory and decision-making), one communication item (ability to make self understood) and one ADL item (eating).
On the evaluation of medication competence, sum score for the analysis consisted of Medication Competence (50 items), and sub-sum scores of Theoretical Medication Competence (30 items), Practical Medication Competence (10 items) and Decision-making Competence (10 items).
The scores are obtained from five MDS items, ie, one communication item (ability to make self understood), three cognitive items (short-term memory if comatose and decision-making), and one item for activities of daily living (eating).
Notably the "Autonomy Preference Index" (API) [ 28] consisting of two subscales (15 item "decision-making preferences" and 8-item "information-seeking preferences") has been widely used in mental health research [ 29- 31].
