%X Study design:Cross-sectional cohort study.  OBJECTIVES:To investigate a mediational model where pain (intensity and interference) and fatigue mediate the relationship between the use of mobility aids and moderate-to-severe depressive symptomatology among ambulatory participants with spinal cord injury (SCI).  Setting:A medical university in the southeastern United States.  METHODS:Ambulatory adults (N=652) with chronic SCI responded to a mail-in survey. The Patient Health Questionnaire-9 was used to assess moderate-to-severe depressive symptomatology. The Brief Pain Inventory was used to assess pain intensity and interference, and the Modified Fatigue Impact Scale-5-item version was used to assess fatigue. Participants self-reported use of mobility aids.  RESULTS:On examining mobility aids used for ambulation, 65% were found to have used at least one aid. Severe pain intensity was reported by 11%, and 14% reported severe pain interference. Disabling fatigue was reported by 10% of the participants. Twenty-one percent (n=138) reported moderate-to-severe levels of depressive symptoms. On examining the relationships between mobility aids and depressive symptomatology, using people as a mobility aid was associated with increased odds of depressive symptomatology (2.6) and always using a wheelchair was associated with lower odds (0.3). However, these relationships were no longer significant after controlling for the mediating variables pain intensity, pain interference and fatigue.  CONCLUSIONS:Pain and fatigue mediate the relationship between usage of certain mobility aids and depressive symptomatology. The use of people to assist in ambulation is associated with greater odds of moderate-to-severe depressive symptomatology, while always using a wheelchair is associated with lower odds.Spinal Cord advance online publication, 14 January 2014; doi:10.1038/sc.2013.164.<p /> <p>Language: en</p>
