Assessment of Vision-Related Quality of Life

A nimble solution to these issues is computerized adaptive testing, which is a method for administering items (questions) from a calibrated item bank.111 CAT iteratively administers from the bank to the respondent items that are selected based on their level of impairment (i.e., it choose the items that will provide the greatest amount of information).112 Subsequent items are selected based on the examinee’s previous responses and selection proceeds until a pre-defined stopping criterion (e.g., measurement precision or number of items) is reached.113 This ensures that items are tailored to the individual’s level of impairment.111 As such, compared to PROMs with a fixed set of items, CATs require fewer items and less time to arrive at equally precise scores; and reduce test-taker burden by asking relevant questions and tailoring the test to test-taker ability level. CAT also facilitates automated data entry and scoring.

In September of 2014, the ALNCCB® created a new volunteer role for an experienced LNCC® to act as a liaison between the testing vendor, the ALNCCB®, and the item writers. This role is intended to assist in meeting the needs of the item writers and to ensure that an adequate number of items for each practice area is available in the item bank. The goal is to keep enough items in the item bank to change the certification test at least every two years and to keep both the certification and practice tests current.
Reliability I: Classical methods
Published in Claudio Violato, Assessing Competence in Medicine and Other Health Professions, 2018
With these abundant resources at their disposal, ETS can obviously do what the individual instructor cannot. The SAT, for example, has multiple forms on any given testing each of which has known form of equivalence reliability. ETS has many thousands of items that are designed for the SAT according to the general procedures described above. As well, new items are constantly developed, added to the tests, and tried out on forms of the test. The item bank, therefore, is constantly being replenished. Each form of the SAT is unique and will never be given as it is again. While these procedures employed by ETS approximate the ideal for test construction and development, they require such huge resources that it has not been practical for classroom use or at least hasn’t been until recently.

Qualitative studies conducted with children show that uveitis has a substantial negative effect on vision-related quality of life (VRQoL).17 However, the impact of uveitis on QoL in adults has been evaluated using only generic or non-disease-specific patient-reported outcome measures (PROMs) and there are no qualitative studies in the literature describing the patient experience of uveitis. Cross-sectional studies in the US, The Netherlands and Brazil have shown that patients with uveitis have significantly worse QoL outcomes using the National Eye Institute Visual Function Questionnaire-25 (NEI -VFQ 25) and the 36-Item Short-Form Health Survey questionnaire (SF-36) compared to controls.18–20 With the exception of one PROM for Birdshot chorioretinopathy, there are no disease-specific PROMs developed for adult uveitis.21 The study aims to explore QoL issues in adults with uveitis using qualitative methodology. The QoL issues identified in this study will be used to develop uveitis – specific QoL item bank. An item bank is a pool of items/questions that are designed to measure a unidimensional construct (e.g. symptoms, physical functioning).22 Using a computerised adaptive testing system (CAT) to administer a targeted set of questions from the larger bank provides a quick and accurate assessment of patient-reported outcomes.23,24This qualitative study is part of the Eye-tem Bank project that aims to develop disease-specific QoL item banks for all eye diseases.25 This paper reports on the findings from focus groups with patients with uveitis.
Applying Item Response Theory to the OPD Structure Questionnaire: Identification of a Unidimensional Core Construct and Feasibility of Computer Adaptive Testing

The 36-item item bank demonstrates adequate psychometric properties, similar to those of comparable item banks assessing constructs that were more precisely defined with a clear unidimensional approach such as the severity of depression or anxiety (Pilkonis et al., 2011). To extend the measurement range and to improve measurement precision across a broader range of the construct, it would be reasonable to develop additional items reflecting low personality pathology. One must note, however, that low personality pathology does not necessarily indicate proper personality functioning, especially in the case of the OPD items. There has been an ongoing discussion about whether the assessment of healthy and disturbed personality could somehow be combined, or whether they are even both expressions of the same common underlying dimensions (Trull & Widiger, 2015). However, further investigation of personality functioning constructs including the OPD domain is needed before such a conclusion can be drawn.
Structural validity and construct validity of the Dutch-Flemish PROMIS® physical function-upper extremity version 2.0 item bank in Dutch patients with upper extremity injuries

The PROMIS Psychical Function item bank has been developed, validated and calibrated in the English language [15,16]. To use the PROMIS item bank in the Netherlands and Belgium, the item bank was translated into the Dutch-Flemish language by the Dutch-Flemish PROMIS Group [17]. The first version of the Dutch-Flemish PROMIS Physical Function item bank (v1.2) contained 121 items [15–17]. This item bank has been validated in Dutch patients with chronic pain, patients undergoing physiotherapy, and patients with rheumatoid arthritis [18–20]. The PROMIS Group continued to improve the item bank, and a separate item bank for upper extremity injuries was developed, containing 46 items; the PROMIS® Physical Function – Upper Extremity (UE) v2.0 item bank [21,22]. Eventually, the item bank will be used as a Computerized Adaptive Test (CAT). The CAT system uses an algorithm that selects questions from the item bank based on the patients’ response to the previous questions. When a predefined precision is reached, the system automatically stops asking questions. The benefit of a CAT is that the number of questions that need to be asked can be reduced to between 4 and 7 items [23].
