BackgroundPhysical function (PF) is a core patient-reported outcome domain in clinical trials in rheumatic diseases. Frequently used PF measures have ceiling effects, leading to large sample size requirements and low sensitivity to change. In most of these instruments, the response category that indicates the highest PF level is the statement that one is able to perform a given physical activity without any limitations or difficulty. This study investigates whether using an item format with an extended response scale, allowing respondents to state that the performance of an activity is easy or very easy, increases the range of precise measurement of self-reported PF.MethodsThree five-item PF short forms were constructed from the Patient-Reported Outcomes Measurement Information System (PROMIS®) wave 1 data. All forms included the same physical activities but varied in item stem and response scale: format A (“Are you able to …”; “without any difficulty”/“unable to do”); format B (“Does your health now limit you …”; “not at all”/“cannot do”); format C (“How difficult is it for you to …”; “very easy”/“impossible”). Each short-form item was answered by 2217–2835 subjects. We evaluated unidimensionality and estimated a graded response model for the 15 short-form items and remaining 119 items of the PROMIS PF bank to compare item and test information for the short forms along the PF continuum. We then used simulated data for five groups with different PF levels to illustrate differences in scoring precision between the short forms using different item formats.ResultsSufficient unidimensionality of all short-form items and the original PF item bank was supported. Compared to formats A and B, format C increased the range of reliable measurement by about 0.5 standard deviations on the positive side of the PF continuum of the sample, provided more item information, and was more useful in distinguishing known groups with above-average functioning.ConclusionsUsing an item format with an extended response scale is an efficient option to increase the measurement range of self-reported physical function without changing the content of the measure or affecting the latent construct of the instrument.Electronic supplementary materialThe online version of this article (doi:10.1186/s13075-017-1273-5) contains supplementary material, which is available to authorized users.

“…Media and communication scholars have started asking with increasing frequency 'what's new in new media?' (Carpentier and Dahlgren, 2014;Ekström et al, 2011;Jones et al, 2011). These studies usefully confront the prevailing uncritical celebration of digital novelties by subjecting new media to historically embedded analyses and comparisons.…”

This article charts the historical stability and continuity of participatory and crowdsourcing practices. Theoretically, it suggests that the blurring of the boundaries between audiences and producers, with the ensuing result of user-generated content, is by no means solely the upshot of new media technological affordances but largely a function of relatively stabilized, genre-specific formal and functional properties, or ‘genre affordances’. Certain referential and performative genres enable interaction between audiences, texts and producers independently of new media technologies because these genres constitute what matters for both producers and audiences in specific historical circumstances. Genres make available shared cultural, social and pragmatic resources for appropriate and desirable being, doing, feeling and thinking. Empirically, this article builds upon an archival study of co-production related to the specific genre of travel guidebooks. It investigates (a) audience feedback in the form of handwritten letters sent to John Murray, a venerable 19th-century British publishing house, and (b) the ways in which John Murray’s yesteryear guidebook producers actively solicited and implemented reader-authored content in professional production practice.
