The results of one-way repeated measures ANOVA with measurement time point as independent variable and interpersonal problems as dependent variable showed that the main effect of measurement time point on interpersonal problems was significant, F(2, 420) = 3.29, p < 0.05, η 2 p = 0.02; post hoc tests revealed that interpersonal problems at time point 3 were higher than at time point 2, with marginal significance ( p = 0.06).
