Overall, participants provided positive feedback on the four items of the PSS and found the measure to be relevant, straight-forward, and easy to understand.
Eight researchers from Australia and Canada with expertise in the development of unmet needs measures for cancer populations were asked to provide critical feedback on the domains, items and response scale of the measure via email.
The development of the measure was based on a review of existing measures and qualitative interviews with patients, and their feedback on the individual items in order to create a measure that was meaningful regardless of the patients' socioeconomic status [ 21].
Feedback on the single-item PE measures confirmed relevance of the item content and further confirmed major themes identified from the qualitative data.
Of particular importance was the participant feedback on the "redness" item, which while both a symptom and sign of psoriasis, appears to be one that is highly subjective and therefore potentially more reliably reportable by patients rather than clinicians.
The initial survey was piloted by four English academic PCPs who were asked to complete a paper-based version of the survey and give written and verbal feedback on the relevance of items, whether the items covered the area of interest and whether they would be able to interpret results from the answers.
During the interviews patients discussed their understanding of the HAE PRO instructions, items and response options and provided feedback on the relevance of items and ease of questionnaire completion.
It is important to note that all of the instructors involved in this study had access to and were involved in giving feedback on the outcome assessment items.
To generate an item list for the assessment of joint awareness in shoulder patients and to collect patient feedback on the comprehensibility of the items and the forgotten joint concept.
Also, we asked the patients to give additional feedback on the questionnaire (comprehensibility, item content, layout etc)., which then further informed modifications of the pilot version.
