“…An approach that may limit patient burden, avoid missed questions, and may be less prone to floor and ceiling effects is computer adaptive testing (CAT) [19,25,26]. CAT uses item response theory to optimize questionnaire administration by administering only relevant items based on the estimated level of function [9,11]. For instance, if a patient says they can walk a mile, it will not ask if they can walk a block.…”

Background To assess disability more efficiently with less burden on the patient, the National Institutes of Health has developed the Patient Reported Outcomes Measurement Information System (PROMIS) Physical Functionan instrument based on item response theory and using computer adaptive testing (CAT). Initially, upper and lower extremity disabilities were not separated and we were curious if the PROMIS Physical Function CAT could measure upper extremity disability and the Quick Disability of Arm, Shoulder and Hand (QuickDASH). Questions/purposes We aimed to find correlation between the PROMIS Physical Function and the Quick-DASH questionnaires in patients with upper extremity illness. Secondarily, we addressed whether the PROMIS Physical Function and QuickDASH correlate with the PROMIS Depression CAT and PROMIS Pain Interference CAT instruments. Finally, we assessed factors associated with QuickDASH and PROMIS Physical Function in multivariable analysis.

“…Perhaps the most important application of IRT in the health field is CAT, a measurement approach in which the selection of items is tailored for each respondent. 29,30 The development of a CAT requires several steps that are not required in the development of a traditional measure, including identification of ''starting'' and ''stopping'' rules. CAT's most attractive advantage is its efficiency.…”

People with schizophrenia frequently have significant problems in community functioning. Progress in developing effective interventions to ameliorate these problems has been slowed by the absence of reliable and valid measures that are suitable for use in clinical trials. The National Institute of Mental Health convened a workgroup in September 2005 to examine this issue and make recommendations to the field that would foster research in this area. This article reports on issues raised at the meeting. Many instruments have been developed to assess community functioning, but overall insufficient attention has been paid to psychometric issues and many instruments are not suitable for use in clinical trials. Consumer self-report, informant report, ratings by clinicians and trained raters, and behavioral assessment all can provide useful and valid information in some circumstances and may be practical for use in clinical trials. However, insufficient attention has been paid to when and how different forms of assessment and sources of information are useful or how to understand inconsistencies. A major limiting factor in development of reliable and valid instruments is failure to develop a suitable model of functioning and its primary mediators and moderators. Several examples that can guide thinking are presented. Finally, the field is limited by the absence of an objective gold standard of community functioning. Hence, outcomes must be evaluated in part by ''clinical significance.'' This criterion is problematic because different observers and constituencies often have different opinions about what types of change are clinically important and how much change is significant.

Future goals for CPIB development include computerized adaptive testing (Cook, O'Malley, & Roddey, 2005).The CPIB was developed using methods recommended and followed by the National Institutes of Health initiative Patient-Reported Outcomes Measurement Information System (PROMIS, nihpromis.org). PROMIS was established to advance the measurement science of patient-reported outcomes across a wide range of health domains .…”

Exploring the Relevance of Items in the Communicative Participation Item Bank (CPIB) for Individuals With Hearing Loss

Purpose: The Communicative Participation Item Bank (CPIB) was developed to evaluate participation restrictions in communication situations for individuals with speech and language disorders. This study evaluated the potential relevance of CPIB items for individuals with hearing loss. Method: Cognitive interviews were conducted with 17 adults with a range of treated and untreated hearing loss, who responded to 46 items. Interviews were continued until saturation was reached and prevalent trends emerged. A focus group was also conducted with 3 experienced audiologists to seek their views on the CPIB. Analysis of data included qualitative and quantitative approaches.Results: The majority of the items were applicable to individuals with hearing loss; however, 12 items were identified as potentially not relevant. This was largely attributed to the items' focus on speech production rather than hearing. The results from the focus group were in agreement for a majority of items. Conclusions: The next step in validating the CPIB for individuals with hearing loss is a psychometric analysis on a large sample. Possible outcomes could be that the CPIB is considered valid in its entirety or the creation of a new questionnaire or a hearing loss-specific short form with a subset of items is necessary. M ost of the life roles in which we engage, such as at home, at work, and in social situations, require communication that involves a bidirectional transfer of information among people. The term communicative participation has been described as "taking part in life situations that involve an exchange of information, ideas, or feelings" (Eadie et al., 2006, p. 309). This term is based on the definition of participation from the World Health Organization (2001) International Classification of Functioning, Disability, and Health (ICF), which defines participation as involvement in life roles. Communication is considered a critical element of life participation by hearing loss experts and individuals with hearing loss (Granberg, Pronk, et al., 2014;Granberg, Swanepoel, Englund, Möller, & Danermark, 2014). According to the ICF and other biopsychosocial frameworks of health, the impact of a health condition on life participation is shaped by a combination of variables, including the nature and extent of physical injury or impairment, the characteristics of the individual, and the environmental context. In a similar manner, the impact that a communication disorder, such as hearing loss, has on a person's participation in life situations might depend on the severity of the hearing loss, the characteristics of that individual, and the listening conditions of the environment, among other issues. Audiologists who have a deep appreciation for how a client's hearing loss influences participation in real-life situations might be better able to meet the habilitation or rehabilitation needs of their clients via amplification, aural rehabilitation, counseling, or other avenues. To achieve these goals, however, clinicians and researchers need valid...
