Resilience in the face of coping with a severe physical injury: A study of trajectories of adjustment in a rehabilitation setting.

Objective: Despite the popularity of the concept of resilience, little research has been conducted on populations in physical rehabilitation settings. Our purpose was to identify three trajectories of psychological adjustment to an acquired severe physical injury characterized by resilience, recovery, or distress in a longitudinal design. Participants: Eighty inpatients with a severe injury at a rehabilitation hospital. The participants had spinal cord injury or multiple traumas. Design: Classification into the three trajectories was based on symptoms of psychological distress (posttraumatic stress disorder, depression, anxiety, and negative affect) and participants’ level of positive affect at admission to and discharge from the rehabilitation hospital. Results: The most common trajectory was the resilience trajectory (54%), followed by the recovery trajectory (25%) and the distress trajectory (21%). The most interesting differences between the trajectories were the result of optimism, affect, social support, and pain. Trait negative and positive affect predicted classification into the trajectories. Conclusions: An adaptation pattern characterized by resilience was found to be the most common response to an acquired severe injury, and trait affect predicts the outcome pattern. Interventions based on resilience are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Olfactory dysfunction, gambling task performance and intracranial lesions after traumatic brain injury.

Objective: To estimate the incidence of olfactory dysfunction across traumatic brain injury (TBI) severity and decision-making deficits with regard to intracranial lesions' location and laterality. Method: A 1-year prospective study including 115 participants (16–55 years) with mild, moderate, and severe TBI. The Brief Smell Identification Test was used 3 months postinjury with a follow-up testing of olfactory dysfunction at 1 year. The Iowa Gambling Task (IGT) and 3 tasks of the Delis–Kaplan Executive Function System were administered 3-months postinjury. MRI was performed 1-year postinjury and TBI severity groups were then divided with respect to frontal, fronto-temporal, diffuse, and no lesions. Results: The incidence of olfactory dysfunction was estimated to be 22.3% at 3 months and 13.5% at 1 year. No significant differences were found on olfactory dysfunction across TBI severity at either check. Anosmia was identified in 10% with severe TBI and 3% with mild TBI. Olfactory dysfunction was associated with verbal fluency tasks. Repeated-measures analysis of variance revealed no significant effect over blocks on IGT, and no main group or interaction effects regarding TBI severity, lesions' location, or laterality. IGT performance at 3-months postinjury was deficient in 83% of persons with intracranial lesions and 71% of those without lesions. Conclusions: Olfactory dysfunction is independent of TBI severity, showing improvements in one third of cases from 3- to 12-months postinjury. However, anosmia was related to TBI severity. There is evidence for marked decision-making deficits after TBI, all subgroups performed similarly and failed to develop an advantageous strategy over time.
