Coated with urethane and scrawled over with words and drawings from the hands of passersby, the mirrors are "designed to complicate reflection and subvert subjective clarity".
After viewing, participants found the "without" version to have better subjective clarity about benefits of screening ("with" 3.4, "without" 4.1, p < 0.01), and to have greater clarity about downsides of screening ("with" 3.2, "without" 3.6, p = 0.03).
The version with the explicit discussion of the option of no screening ("with" version) was rated subjectively as less strongly in favor of CRC screening, but had lower subjective rating of clarity and a lower overall rating.
Other subjective measures, including clarity of information, ability to sort out what was important, ability to help make a decision, and overall impression of the decision aid, used response categories of: 1-Poor, 2- Fair, 3- Good, 4-Very Good, 5-Excellent.
Question design has a measurable effect on the overall usability and security of the PBAF approach, which needs particular consideration to address clarity, ambiguity, relevance, subjective, and objective information.
"It might be interpreted as cumbersome by some," Calvert said, adding that the intention of the changes is to provide clarity and ultimately reduce subjective interpretation by both developers and city staff.
Likert response categories (5-point) were used for subjective measures of content (eg. clarity, balance in favor/against screening, and overall rating), and screening interest.
The clarity score was a subjective scale judged against behavioural markers such as reading back important information, asking questions.
Our primary outcomes were subjective measures of decision aid content such as clarity and balance, and our secondary measures included knowledge and interest and intent to be screened.
The lack of information and conceptual clarity about MCI led to a pervasive subjective sense of ambiguity.
This includes a consideration of methods for experimentally assessing the generation, maintenance, inspection and transformation of mental images; as well as subjective measures of characteristics such as image vividness and clarity.
