Abstract:
Study investigated whether demographic, injury, health, and functional factors similarly have the same predictive association with both somatic and nonsomatic symptoms of depression, and whether somatic and nonsomatic symptoms of depression have the same association with quality of life (QOL). One-year follow-up assessment data from 4,976 participants with traumatic SCI enrolled in the Spinal Cord Injury Model Systems National Database, obtained between 2006 and 2011, were analyzed. Somatic and nonsomatic symptoms of depression were measured using the Patient Health Questionnaire-9 and QOL was evaluated by the Satisfaction With Life Scale. Structural equation modeling showed that the hypothesized model provided a good fit to the data, but modification of the model led to a significant improvement in model fit. The health-related factors including pain severity, pain interference, and health status were similarly associated with both somatic and nonsomatic symptoms of depression. QOL was negatively associated with nonsomatic symptoms of depression but was unrelated to somatic symptoms of depression. Findings suggest that differences exist in the association between demographic, health, function, participation, and somatic and nonsomatic symptoms of depression as well as on QOL. Assessment of depression after SCI should include a careful assessment of health concerns given the relation between health-related factors and both somatic and nonsomatic symptoms of depression. Treatments of depressive symptoms may be improved by targeting health concerns, such as pain, along with a specific focus on nonsomatic symptoms to improve the QOL.
