Abbreviations: SDM, shared decision-making; SP, standardized patient.
Effect size calculated as Cohen's d, whereas d = difference between the group means / SD of either group (Cohen's d of 0.2 = a small effect, 0.5 = a moderate effect, and 0.8 = a large effect).
Assessed by analysis of videotapes of encounters with SP, using a newly developed rating scale score derived from the OPTION scale, ranging from 0 (least involved) to 100 (most involved).
Assessed by means of a questionnaire, using a 5-point scale with ratings between 1 point (lowest for “strongly disagree”) and 5 points (highest for “strongly agree”).
Assessed by means of a questionnaire, using a 5-point scale with ratings between 1 point (lowest for “never”) and 5 points (highest for “daily”).
