Abstract:
This study reports normative data of depressive mood in Brazil, using a Portuguese version of the Depression Adjective Check Lists (DACL; Lubin, 1981, in press). Participants (N = 1,063) were college students drawn from randomly selected courses in 10 Brazilian universities. Cross-cultural comparisons showed that this Brazilian sample had significantly higher depressive scores compared to Hispanic (p < .01), American (p < .01), and Israeli (p < .05) samples. The results also indicated that Brazilian females (p < .05) and young adults (p < .05) reported significantly more depressive mood than males and older adults, respectively. All reliability (internal consistency, split-half, and alternate form) and concurrent validity measures were found to be appropriate and compared well to other cross-cultural samples.
