*Post hoc Bonferroni pairwise comparisons (p<0.05) at baseline.
†Post hoc Bonferroni pairwise comparisons (p<0.05) at follow-up.
‡Significant differences between baseline and 12-month follow-up (repeated measures t-test p<0.05).
§Owing to a significant ‘floor’ effect, in that few participants in the overall sample endorsed the hopelessness-related items, between-group analyses were not conducted for this variable.
