evidence final name · Stress Caused
Minimal System Usability
Expressions activating this band contain little or no clear evaluation of how usable a system or service is, often focusing on neutral service availability, administrative details, or general acceptability rather than the experience of operating it.
Low System Usability
Expressions activating this band describe basic ease or difficulty in interacting, communicating, or obtaining needed support, with usability framed in broad and somewhat diffuse terms. The experience centers on whether engagement feels manageable and accessible in everyday use.
Moderate System Usability
Expressions activating this band describe a system as workable and satisfactory for completing tasks, communicating, and filling out forms, while still acknowledging friction, effort, or feeling bogged down. Usability is present as functional adequacy rather than seamless operation.
High System Usability
Expressions activating this band describe a system as easy to learn, pleasant to use, and capable of supporting productive interaction with relatively little strain. The experience includes confidence that the system's features and interface support intended goals.
Exceptional System Usability
Expressions activating this band describe a system as intuitive, straightforward to master, and easy to control, with quick recovery from mistakes. Use feels natural, clear, and efficient even when errors occur.

Minimal Stress Caused: Expressions show no meaningful stress caused content. The proxy is effectively absent. Expressions activating this band are unrelated to stress caused.
Emerging Stress Caused: Stress caused is experienced here as observable behavioral patterns associated with problematic or disordered functioning. This is the first band where stress caused becomes detectable. Expressions activating this band engage with stress caused at a level associated with formal behavioral assessment.
Elevated Stress Caused: Stress caused is clearly present at this level. Unlike the band below, where stress caused was characterized by the behavioral form, the proxy here has shifted in character. The facets that dominated at lower levels have receded. Expressions activating this band reflect stress caused at this level of intensity.
Severe Stress Caused: Stress caused is present here in a general or mixed form without a single dominant facet. Unlike the band below, where stress caused was characterized by a general form, the proxy here has shifted in character. The facets that dominated at lower levels have receded. Expressions activating this band may reflect general or diffuse stress caused.
