“…Moreover, the expert panel functioned to ensure that the VISION-Cog has simple instructions, appropriate levels of difficulty, and a manageable duration of assessment so that it can be performed comfortably by older adults. This is indispensable because other commercially available visually independent batteries are cognitively demanding for older adults as they are intended for the vocational assessment of young adults 29 33…”

ObjectivesCurrent cognitive screening and diagnostic instruments rely on visually dependent tasks and are, therefore, not suitable to assess cognitive impairment (CI) in visually impaired older adults. We describe the content development of the VISually Independent test battery Of NeuroCOGnition (VISION-Cog)–a new diagnostic tool to evaluate CI in visually impaired older Singaporean adults.DesignThe content development phase consisted of two iterative stages: a neuropsychological consultation and literature review (stage 1) and an expert-panel discussion (stage 2). In stage 1, we investigated currently available neuropsychological test batteries for CI to inform constructions of our preliminary test battery. We then deliberated this battery during a consensus meeting using the Modified Nominal Group technique (stage 2) to decide, via agreement of five experts, the content of a pilot neuropsychological battery for the visually impaired.SettingSingapore Eye Research Institute.ParticipantsStakeholders included researchers, psychologists, neurologists, neuro-ophthalmologists, geriatricians and psychiatrists.Outcome measurepilot VISION-Cog.ResultsThe two-stage process resulted in a pilot VISION-Cog consisting of nine vision-independent neuropsychological tests, including the modified spatial memory test, list learning, list recall and list recognition, adapted token test, semantic fluency, modified spatial analysis, verbal subtests of the frontal battery assessment, digit symbol, digit span forwards, and digit span backwards. These tests encompassed five cognitive domains–memory and learning, language, executive function, complex attention, and perceptual-motor abilities. The expert panel suggested improvements to the clarity of test instructions and culturally relevant test content. These suggestions were incorporated and iteratively pilot-tested by the study team until no further issues emerged.ConclusionsWe have developed a five-domain and nine-test VISION-Cog pilot instrument capable of replacing vision-dependent diagnostic batteries in aiding the clinician-based diagnosis of CI in visually impaired older adults. Subsequent phases will examine the VISION-Cog’s feasibility, comprehensibility and acceptability; and evaluate its diagnostic performance.

“…Although several visually independent neuropsychological tests to evaluate CI in this special population have been developed previously, they have inherent limitations. For example, the Haptic Intelligence Scale and Tactual Progressive Matrices, are no longer commercially available,10 while commercially available batteries, such as the Cognitive Test for the Blind and the Neuropsychological Assessment of Adults with Visual Impairment,11 12 were constructed primarily for young adults, and therefore comprise cognitively demanding tests inappropriate for older adults due to complicated instructions, high levels of difficulty and long durations of assessment 11–13. To date, valid and reliable neuropsychological test batteries suitable for evaluating CI among older adults with VI are unavailable.…”

ObjectivesWe pilot-tested theVISuallyIndependent test batteryOfNeuroCOGnition (VISION-Cog) to determine its feasibility, comprehensibility and acceptability in evaluating cognitive impairment (CI) in visually impaired older Asian adults.DesignThe VISION-Cog was iteratively fine-tuned through pilot studies and expert-panel discussion. In the first pilot study (Stage 1), we recruited 15 visually impaired and cognitively normal participants aged ≥60 years to examine the pilot VISION-Cog’s feasibility (length of time to administer), comprehensibility (clarity of instructions) and acceptability (participant burden). We then presented the pilot results to the expert panel (Stage 2) who decided via agreement on a revised version of the VISION-Cog. Subsequently, we conducted a second pilot study (Stage 3) on another four participants to ascertain improvement in feasibility, comprehensibility and acceptability of the revised version.SettingSingapore Eye Research Institute.ParticipantsNineteen Asian adults aged ≥60 years with visual impairment (defined as near visual acuity worse than N8) were recruited.Outcome measureRevised VISION-Cog.ResultThe VISION-Cog was deemed feasible, taking approximately 60 min to complete on average. All participants agreed that the test instructions were clear, and the battery did not cause undue discomfort or frustration. The data collector rated all tests as very user-friendly (score of 5/5). Minor modifications to the pilot VISION-Cog were suggested by the panel to improve its safety, clarity of instructions and content validity, which were incorporated and iteratively tested in the second pilot study until no further issues emerged.ConclusionsUsing an iterative mixed-methods process, we have developed a feasible, comprehensible and acceptable 5-domain and 9-item visually independent VISION-Cog test battery suitable to assist CI diagnosis in older adults with visual impairment. We will assess its diagnostic potential against clinician-based assessment of CI in subsequent phases.
