ObjectiveTo identify associations between objective and self-reported measures of physical activity (PA) and relationships with depression and satisfaction with life (SWL) in persons with spinal cord injury (SCI).DesignRetrospective, cross-sectional study of objectively measured wheelchair propulsion (WCP) from two studies in which an odometer was attached to participants' wheelchairs to record daily speed and distance. Self-reported data was collected in a separate study examining dyspnea, PA, mood, and SWL.SettingOut-patient clinic in a rehabilitation center.Participants86 individuals with traumatic SCI who use a manual wheelchair.InterventionsNot applicable.Main Outcome Measure(s)Objective measures of PA included average daily distance and speed of WCP measured by an odometer. Self-report questionnaires included demographics, the 24-hour recall of transfers, Physical Activity Recall Assessment for People with SCI, the Patient Health Questionnaire (PHQ-2) to document depressive symptoms, and the Satisfaction with Life Scale (SWLS).ResultsBoth objective measures of WCP, average daily distance and speed, were predicted by the combination of self-reported daily time away from home/yard and lower frequency of car transfers (r=0.367, p=0.002 and r=0.434, p<0.001 respectively). Daily distance of WCP was negatively correlated with depression (PHQ-2) (r= -0.309, p=0.004). Time in leisure PA was the only significant predictor of SWLS scores (r=0.321, p=0.003).ConclusionsShort-term recall of hours away from home/yard not spent driving or riding in a vehicle is suggested as a self-report measure that is moderately related to overall WCP PA in this population. Results of this study suggest that depression is related to decreased PA and WCP activity while, SWL is related to leisure PA.
