Investigating the function spiral in later life: Aging attitudes, physical activity, and gait
By Whitehead BR
This study tests the Function Spiral Model, which proposes that functional decline often occurs prematurely: negative aging attitudes reduce activity engagement, which then advances functional decline via physical deconditioning. A total of 89 adults aged 61-96 (M = 77) years completed a questionnaire assessing aging attitudes and physical activity and participated in a follow-up assessment of gait/balance and function. Results supported the process model: physical activity mediated the impact of negative aging attitudes on gait/balance, and gait/balance mediated the impact of physical activity on function. Findings highlight multiple points of intervention that could mitigate the acceleration of functional decline in later life.
