Interest in testing self and child: effect of predictive power of the test. Legend: Shown are the proportions of participants who expressed interest in genetic testing for mood disorders for self and/or a child, separately for a modestly predictive (“20 % certainty”) test (N = 52) and for a highly predictive (“90 % certainty”) test (N = 51 participants who answered both questions). Absolute counts are shown above each bar. The effect of predictive power was highly significant, e.g., for interest in testing children, p = 0.000021 (sign test). The proportion of participants who would test children (child only or self and child) was 53 % for a modestly predictive test (27/51) and 90 % for a highly predictive test (46/51)
