Table 3. Proportion of participants at high risk for suicidal behavior at T0, T1, and T2.
| SIDAS scores ≥ 21 (high risk) N (%) | ORa [95% CI] | t | p | NNTd [95% CI] | ||
|---|---|---|---|---|---|---|
| LifeBuoy (n, %) | LifeBuoy-C (n, %) | |||||
| T0 | 136 (59.6) | 129 (57.1) | 0.97 [0.89, 1.07] | t(930) = −0.55 | 0.58 | - |
| T1b | 36 (24.7) | 62 (44.9) | 1.22 [1.10, 1.37] | t(930) = 3.59 | <0.001 | 5 [4, 11] |
| T2c | 26 (26.0) | 39 (39.8) | 1.14 [1.00, 1.30] | t(930) = 2.01 | 0.04 | 8 [4, 119] |
aOR reflects odds of being flagged as at risk for the LifeBuoy-C condition relative to the LifeBuoy condition. The generalized linear mixed model used to generate the ORs incorporated all participants with at least 1 data point.
bNumber of participants who completed T1 SIDAS assessment n = 284 (n = 138 control, 146 intervention).
cNumber of participants who completed T2 SIDAS assessment n = 198 (n = 98 control, 100 intervention).
dNNT: the number of participants that need to be treated to obtain one participant scoring < 21 on the SIDAS.
OR, odds ratio; NNT, number needed to treat; SIDAS, Suicidal Ideation Attributes Scale; T0, baseline; T1, postintervention; T2, 3-month postintervention.
