Brief summary
The purpose of this study is to determine whether Antidepressant Decision Aid for Major Depressive Disorder is feasible and effective in involving patients in the decision-making process when initiating pharmacotherapy.
Detailed description
To examine the ability of the patient decision aid to enhance shared decision making and preparedness to make decisions pertaining to antidepressant therapy. The research team has systematically developed an Antidepressant Decision Aid for Major depressive disorder patients (ADAM) according to the International Patient Decision Aids Standards (IPDAS) and the Ottawa Decision Support Framework. This is a posttest-only study with nonequivalent groups to evaluate the effect of the antidepressant decision aid on patient and physician perception of shared decision making as well as patient preparedness for making pharmacotherapeutic decisions compared usual care.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Shared Decision Making_Patient Perspective | Immediately after the clinical encounter | The patient version of the Shared Decision Making scale (SDM-Q-9) measures the extent to which patients are involved in the decision-making process from the patient's perspective. It consists of nine items rated on a six-point Likert-type scale fromcompletely disagree= tocompletely agree=. Adding the score of all the items leads to a raw total between 0 and 45. Multiplying the raw score by 20/9 provides a transformed score ranging from 0 to 100, higher scores indicate a greater extent of SDM. |
| Shared Decision Making_Physician Perspective | Immediately after the clinical encounter | The physician version of Shared Decision Making scale (SDM-Q-Doc) measures the extent to which patients are involved in the decision-making process from the physician's perspective. It consists of nine items rated on a six-point Likert-type scale fromcompletely disagree= tocompletely agree=. Adding the score of all the items leads to a raw total between 0 and 45. Multiplying the raw score by 20/9 provided a transformed score ranging from 0 to 100, higher scores indicate a greater extent of SDM. |
| Preparation for Decision Making_Patient Perspective | Immediately after the clinical encounter | The patient version of the Preparation for Decision-Making Scale (PDMS) assesses the patient's perception of how the PDA helped them recognize that a decision needs to be made, preparing them to communicate with their practitioner and promote patient involvement in the decision-making process. Higher scores indicate a higher perceived level of preparation for decision making. |
