title: The relationship of hardiness and depression to disability in institutionalized older adults.
abstract: Disability is an often expensive and sometimes preventable consequence of chronic illness. This study explored the relationship of hardiness and depression to disability in a sample (N = 58) of aged, institutionalized persons, controlling for length of stay (LOS) in the nursing home and physical health status. Using hierarchical regression analysis, LOS and physical health status accounted for 14.7% of the variance in disability (p = .01). Hardiness explained an additional 10.5% of the variance (p = .008). Depression accounted for an additional 7.4% (p = .02) of the variance in disability. The results of this study support the premise that psychological factors may increase a person's degree of disability beyond what might be expected from the physical illness or injury alone.
