The Perceived Control Model of Falling: Developing a unified framework to understand and assess maladaptive fear of falling

Abstract

Background: fear of falling is common in older adults and can have a profound influence on a variety of behaviours that increase fall risk. However, fear of falling can also have potentially positive outcomes for certain individuals. Without progressing our understanding of mechanisms underlying these contrasting outcomes, it is difficult to clinically manage fear of falling.

Methods: this paper first summarises recent findings on the topic of fear of falling, balance and fall risk—including work highlighting the protective effects of fear. Specific focus is placed on describing how fear of falling influences perceptual, cognitive and motor process in ways that might either increase or reduce fall risk. Finally, it reports the development and validation of a new clinical tool that can be used to assess the maladaptive components of fear of falling.

Results: we present a new conceptual framework—the Perceived Control Model of Falling—that describes specific mechanisms through which fear of falling can influence fall risk. The key conceptual advance is the identification of perceived control over situations that threaten one’s balance as the crucial factor mediating the relationship between fear and increased fall risk. The new 4-item scale that we develop—the Updated Perceived Control over Falling Scale (UP-COF)—is a valid and reliable tool to clinically assess perceived control.

Conclusion: this new conceptualisation and tool (UP-COF) allows clinicians to identify individuals for whom fear of falling is likely to increase fall risk, and target specific underlying maladaptive processes such as low perceived control.
