At baseline, the two groups of nurses shared the same level of certainty regarding their ability to assess for depressed mood. On average, the usual care group scored 2.6 ± 0.8 (1 = very uncertain to 4 = very certain), and the intervention nurses scored 2.6 ± 0.7. One year later, the intervention group displayed a statistically significant increase in confidence (3.3 ± 0.6; degrees of freedom (df) = 14, t = 4.18, P<.001), whereas the usual care group’s confidence remained unchanged (2.8 ± 0.6; df = 13, t = 1.00, P = .34). Likewise, both groups of nurses shared a similar level of certainty in assessing for diminished interest or pleasure in most activities at baseline (mean 2.6 ± 0.8 for the usual care group, mean = 2.7+0.7 for the intervention group; df = 27, t = 0.75, P = .46). One year later, the intervention nurses showed a statistically significant increase in confidence in assessing for diminished interest or pleasure in most activities (3.1 ± 0.8; df = 14, t = 2.17, P = .048), whereas the usual care group remained unchanged (2.7 ± 0.5; df = 13, t = 0.37, P = .72). Furthermore, nine of 15 intervention nurses reported an improvement in confidence in assessing depressed mood 1 year later, versus only four of 14 usual care group nurses (Fisher exact test P = .07). In assessing for diminished interest or pleasure in most activities, eight of 15 intervention group nurses reported improved confidence, versus two of 14 usualcare nurses (Fisher exact test P = .03).
