4. Values congruent with chosen option.

Study	Scale used	Timing	N decision aid	Decision aid ‐ mean	N comparison	Comparison ‐ mean	Notes
Arterburn 2011	Percent match procedures described by Sepucha et al (2007; 2008). For values items were most predictive and used to specify logistic models to estimate predicted probability of selecting surgery > 0.5.	Postintervention	75	—	77	—	The intervention group experienced a more rapid early improvement in value concordance immediately after the intervention compared to control
Berry 2013	Concordant when men reported:a) sexual function influenced decision and they had radiation therapy; b) bowel function influenced decision and they had surgery; c) all effects influenced decision and they had surveillance	6 months postintervention	239	—	209	—	No difference OR = 0.82; 95% CI 0.56 to 1.2
Frosch 2008a	Concordance between participant's preferences and values for potential outcomes related to the decision and the choice made	within weeks	155	—	151	—	Men assigned to the decision aid who chose not to have a PSA test rated their concern about prostate cancer lower than did men who requested a PSA test. Men assigned to usual care provided similar ratings of concern about prostate cancer regardless of their PSA decision. There was no statistically significant difference between groups.
Legare 2008a	—	—	—	—	—	—	Women valuing of non‐chemical aspect of natural health products was positively associated with their choice of nature health products, P = 0.006. No difference between groups
Lerman 1997	Association between values and choice	—	—	—	—	—	No difference; between‐group differences were not reported
Vandemheen 2009	Congruence between personal values and decision	3 weeks	70	—	70	—	Patient choices were consistent with their values across both randomized groups

DA: decision aid; SD: standard deviation.
