This scale measures how satisfied the participant is with their decision about whether or not to undergo deep brain stimulation surgery. The areas of satisfaction include how informed they were, if the decision was the best for them, if the decision was consistent with their values and if they had as much input as they wanted. Scores range from 6 to 30. Higher scores indicate higher satisfaction with the decision.
