We examined the relationship between depression and anxiety, language, and functional outcomes in persons with traumatic brain injury (TBI). The sample consisted of 48 acute TBI (ATBI: 23 Spanish-English Bilinguals; 25 English monolinguals), 30 chronic TBI (CTBI: 17 Spanish English Bilinguals; 12 English monolinguals), and 47 healthy comparison (HC: 29 Spanish-English Bilinguals; 18 English monolinguals) participants. The Hospital Anxiety and Depression Scale was used to measure depression (HADS-D) and anxiety (HADS-A). The Mayo Portland Adaptability Inventory-4 (MPAI-4) was used to measure functional outcomes (ability, adjustment, participation). An ANCOVA, controlling for age, revealed the ATBI group reported lower anxiety levels compared to the CTBI group, p = 0.034 np2 = 0.06. HC participants demonstrated significantly higher functional ability compared to both TBI groups, p < 0.05, np2 = 0.08–0.19. The ATBI group demonstrated worse participation scores compared to the CTBI and HC groups, p = 0.001, np2 = 0.11. Pearson correlations revealed mood was related to functional status in ATBI monolinguals (HADS-A: r = 0.29–0.64; HADS-D, r = 0.49–0.62). Monolingual participants with ATBI demonstrated correlations between depressive symptoms and functional adjustment (r = 0.57, p = 0.005) and ability (r = 0.44, p = 0.034). For monolinguals with CTBI, HADS-A correlated with functional outcomes, r = 0.60–0.66, p < 0.05. For bilinguals with CTBI, functional outcomes correlated with HADS-A, r = 0.53–0.66, p < 0.05, and HADS-D, r = 0.54–0.66, p < 0.05. For HC monolinguals, functional outcomes correlated with HADS-A, r = 0.53–0.70, p < 0.05, and HADS-D, r = 0.50–0.72, p < 0.05. Finally, for HC bilinguals, functional outcomes correlated with HADS-A, r = 0.59–0.68, p < 0.05. Our results suggest that a relationship between anxiety and depressive symptoms is related more to functional outcomes in monolingual TBI survivors compared to bilingual TBI survivors.
