Predictors of Psychological Distress and Confidence Negotiating Physical and Social Environments Among Mobility Device Users.

Objective: We conducted an intersectional analysis to explore how demographic characteristics and mobility device use were associated with psychological distress (depression and anxiety) and confidence negotiating physical and social environments.

Design: Cross-sectional data were collected using the Hospital Anxiety and Depression Scale, modified Wheelchair Use Confidence Scale, and self-reported functional independence scale.

Participants: The sample included 105 participants. Primary mobility devices used included mobility scooters (27%), power wheelchairs (26%), manual wheelchairs (25%), walkers (11%), and cane or crutch (12%). The mean age of participants was 58 yrs, 53% were female, and 52% lived alone and were functionally independent with the use of assistive technology.

Results: We were able to explain between 39% and 65% of the variance (adjusted R2) in the dependent variables with parsimonious regression models. Age was an independent predictor of all outcomes. Women were less confident negotiating the physical environment, and walker use was associated with depression and lower confidence negotiating physical environments, but increased confidence negotiating social environments.

Conclusions: Age is associated with psychosocial outcomes for assistive device users, and those who use walkers may experience increased challenges with depression and negotiating the physical environment. Pending confirmatory research, the findings may have important implications for targeted interventions related to device provision.
