The multiple pathways through which stress can influence health behaviors may become especially apparent in middle-aged and older adults. Not only does poor health increase the urgency for behavior change and thus present a perceived threat, but the lack of resources, such as knowledge of how to implement change, and presence of barriers, such as limited time due to stressful jobs, fear of negative effects, potential to fail, or uncertainty of beneficial outcomes, all contribute to making behavior change a daunting and stressful endeavor. Conversely, many behavior change techniques can be conceptualized as stress management techniques. These techniques can operate by reducing threat perception and/or increasing access to resources, often via provision of informational support.
