Table 1. Descriptive Statistics for the Modified Beck Depression Inventory (MBDI).

Period A
(N = 139)
Period B
(N = 177)
Period C
(N = 157)
MBDI Time 1 Time 2 Time 3 Time 4 Time 5 Time 6
M 9.2 8.1 7.0 7.1 6.5 6.2
SD 9.4 9.4 8.7 9.7 7.7 10.0

Note. We conducted paired t tests of MBDI scores at the two assessments within each period. These two time points were before and after each of the three exams for those students who received a disappointing exam grade (n = 213). Within period, scores only differed significantly for Period A (p = .04).
