“…Self-report instruments used to assess visual functioning include the National Eye Institute Visual Functioning Questionnaire (NEI-VFQ) (Mangione et al 2001), the Impact of Vision Impairment Questionnaire (IVI) (Weih et al 2002), and the Activity Inventory (AI) Massof et al 2007). In our study the AI was adopted to estimate person measures, mostly because it has been developed and used specifically for individuals with low vision and we had access to the item calibration file Goldstein et al 2014).…”

PurposeGeneric instruments to assess health utilities can be used to express the burden of health problems in widely used indexes. That is in contrast with what can be obtained with condition-specific instruments, outcomes are very specific and difficult to compare across conditions. The purpose of this study was to assess health and visual outcomes and its determinants in patients with visual impairment (VI) using the EQ-5D-3L and the Activity-inventory (AI). MethodsParticipants were recruited in different hospitals during the PCVIP-study. A total of 134 patients with acuity 0.30 logMAR or less in the better eye were interviewed. The AI includes 46 goals split between three objectives: social functioning, recreation and daily living, was used to measure visual ability. The EQ-5D consists of five questions covering one domain each and was used to provide a measure of health states. Responses to each domain were combined to produce a single individual index.ResultsThe AI and the EQ-5D-3L showed enough discriminatory power between VI levels (p<.001) and their results were strongly correlated r(134)=.825, (p<.001). Explanatory factors for visual ability were level of VI in better eye, age and gender, R 2 =.43, (p<.001). Explanatory factors for the EQ-5D-3L were level of VI in the better eye, comorbidities and gender, R 2 =.36, (p<.001). ConclusionsOur results showed that the EQ-5D-3L is useful when characterizing the burden of VI and to compute, when necessary, quality-adjusted-life-years (QALY) changes due to VI. However, is important to consider that the EQ-5D-3L uses a coarse response scale, assesses a limited spectrum of domains and is influenced by comorbidities. This might limit its responsiveness to small changes in visual ability.

“…The AI first requires the participant to rate the importance of a goal (eg, read newspaper), and then rate the difficulty of the tasks nested under that goal (eg, read headlines) as "not difficult" (= 0), "slightly difficult" (= 1), "moderately difficult" (= 2), "very difficult" (= 3), "impossible to do without someone else's help" (= 4) or "not applicable" (= 5). 9 If a goal was not rated as important to the individual, then it was not included in the final scoring. The Depression, Anxiety and Stress Scale (DASS) was administered to assess subjective well-being.…”

Adding access to a video magnifier to standard vision rehabilitation: initial results on reading performance and well-being from a prospective, randomized study

Purpose-Both optical and electronic magnification are available to patients with low vision. Electronic video magnifiers are more expensive than optical magnifiers, but they offer additional benefits, including variable magnification and contrast. This study aimed to evaluate the effect of access to a video magnifier (VM) added to standard comprehensive vision rehabilitation (VR).Methods-In this prospective study, 37 subjects with central field loss were randomized to receive standard VR (VR group, 18 subjects) or standard VR plus VM (VM group, 19 subjects). Subjects read the International Reading Speed Texts (IReST), a bank check, and a phone number at enrollment, at 1 month, and after occupational therapy (OT) as indicated to address patient goals. The Impact of Vision Impairment (IVI) questionnaire, a version of the Activity Inventory (AI), and the Depression Anxiety and Stress Scale (DASS) were administered at enrollment, 1 month, after OT, 1 month later, and 1 year after enrollment. Assessments at enrollment and 1 month later were evaluated.Results-At 1 month, the VM group displayed significant improvement in reading continuous print as measured by the IReST (P = 0.01) but did not differ on IVI, AI, or DASS. From enrollment to 1 month all subjects improved in their ability to spot read (phone number and check; P < 0.01 for both). The VM group improved in their ability to find and read a number in a phone book more than the VR group at 1 month after initial consultation (P = 0.02). All reported better well-being (P = 0.02).Conclusions-All subjects reported better well-being on the IVI. The VM group read faster and was better at two spot reading tasks but did not differ from the VR group in other outcome measures.

PURPOSE.To determine factors associated with the level of adjustment to vision loss in a cross-sectional sample of adults with mixed visual impairment. METHODS.One hundred participants were administered the Acceptance and Self-Worth Adjustment Scale (AS-WAS) to assess adjustment to vision loss. The severity of vision loss was determined using binocular clinical visual function assessments including visual acuity, contrast sensitivity, reading performance, and visual fields. Key demographics including age, duration of visual impairment, general health, education, and living arrangements were evaluated, as were self-reported vision-related activity limitation (VRAL), depression, social support, and personality.RESULTS. Multivariate analysis showed that higher levels of depressive symptoms (b ¼ À0.26, P < 0.01) and of the personality trait neuroticism (b ¼À0.33, P < 0.001), and lower levels of the personality trait of conscientiousness (b ¼ 0.29, P < 0.01), were associated with poorer adjustment to vision loss, explaining 56% variance.CONCLUSIONS. Adjustment to vision loss is significantly associated with depression and certain traits of personality (specifically neuroticism and conscientiousness), independent of the severity of vision loss, VRAL, and duration of vision loss. The results suggest certain individuals may be predisposed to exhibiting less adjustment to vision loss due to personality characteristics, and exhibit poorer adjustment owing to or as a consequence of depression, rather than due to other factors such as the onset and severity of visual impairment.

The Activity Inventory: An Adaptive Visual Function Questionnaire

Abstract: Visual ability is a composite variable with two factors; one most heavily influences reading function and the other most heavily influences mobility function. Subsets of items within the AI and different VFQs all measure the same visual ability variable.
