Objectives: The objective of this study was to identify predictors of quality of life (QoL) in a sample of individuals with SCI.
Designs: Individuals were recruited from a SCI outpatient clinic in Ontario, Canada. Sociodemographic data and clinical health information was collected. The following outcome measures were completed: Euro Quality of Life (EQ-5D) – overall health item; Patient Health Questionnaire-9 (PHQ-9), Generalized Anxiety Disorder 7 item (GAD-7); Rosenberg Self-Esteem Scale (RSE), Adult Dispositional Hope Scale (ADHS), Anxiety Sensitivity Index (ASI), and Acceptance and Action Questionnaire (AAQ). Associations between all variables and QoL were determined using stepwise regression modelling.
Results: The sample consisted of 80 individuals (35 females) with a mean age of 59.4±13.2 years and mean time since injury of 12.3±13.3 years. Simple linear regressions demonstrated that all variables were significantly correlated with QoL except for time since injury (p=.944) and gender (p=.623). Significant sociodemographic variables were entered first in the stepwise regression model, followed by the outcome measures. The model showed that only PHQ-9 (R2 change=0.186; p=.001) and ADHS (R2 change=0.059; p=.039) were retained in the model as significant predictors of QoL whereas GAD-7, RSE, ASI, and AAQ were not. The overall model fit was R2=0.245 (p=.039).
Conclusions: The results underscore how both depression and dispositional hope is associated with one’s QoL. Continued research on interventions that reduce depression and increase hope may improve QoL in the SCI population.
