2.1. Study Participants

A prospective one-year follow-up was conducted with a cohort of adults with ABIs from 26 rehabilitation centers that provide health and social services in Spain. The ABI participants had to meet the following inclusion criteria: (a) to have an ABI, (b) to be at least 16 years, (c) to attend an ABI-specific center, and (d) to have signed an informed consent form. The exclusion criteria were the following: (a) to be in a state of coma or having minimum consciousness, (b) to suffer from global aphasia, and (c) not to be able to understand or answer most questions. The individuals with ABIs responded to a QoL measure and a series of complementary questionnaires. Of the 402 participants in the baseline, 199 (49.5%) dropped out at the one-year follow-up due to the end of their rehabilitation, death, or refusal to continue in the study.
