“…2) Option sorting analysis showed that the curve peak of 0, 1, 2, 3 scores were separated from each other and in the same order, indicating the four-point Likert response rating scale was reasonable-a phenomenon also reported in the validation of other vision scales [31][32] . The most useful classification of asthenopia in clinical practice is also four-point (non, mild, moderate and severe asthenopia) [1] , which was consistent with the score of each symptom and helpful for the classification according to the score.…”

AIM: To develop the 17-item Asthenopia Survey Questionnaire (ASQ)-17 by Rasch analysis, and to generate a predictiveness score. METHODS: Totally 739 participants were recruited and 680 were involved in the result analysis in this prospective, cross-sectional study. Three rounds of Rasch analysis were used to analyze the psychometric characteristics of items and options. RESULTS: Phase 1 assessed the original ASQ-19, adjusted the item scoring mode to a four-point Likert response rating scale and combined the 18th and 19th items into a new item. Phase 2 deleted the 11th item. Phases 3 and 4 assessed the new ASQ-17. All the evaluation indexes of ASQ-17 were acceptable. The Infit and Outfit MnSq values of items were 0.67-1.48, the variance explained by the principal component and the unexplained variance explained by the first contrast were 53.90%-59.40% and 1.50-1.80 in three dimensions. The curve peaks of scores in each dimension were separated and in the same order. The PSR and PSI values were 2.80 and 0.89, respectively. The mean scores of dimensions A (9.5±4.1 vs 3.5±3.2), B (7.3±3.3 vs 2.5±2.7), C (4.3±2.2 vs 1.4±2.0) and total (21.1±8.1 vs 7.4±7.0) in asthenopia participants were significantly higher than those without asthenopia (all P<0.001). The area under the curve in two groups was 0.899 (P<0.001). Youden’s index was up to the maximum value of 0.784 when the cut-off value was 12.5. CONCLUSION: ASQ-17 has stronger option sorting and suitability than ASQ-19. It is an effective assessment tool for asthenopia with an optimal cut-off threshold value of 12.5, which is suitable for diagnosis and curative effect evaluation.

“…The study used the convenience sampling which cannot represent all population with visual impairment. The questionnaire interview is based on the ELVQoL [17], so does not include the specific needs such as education for children. Despite these limitations, this study is among the first to investigate the needs for visual improvement of patients with visual impairment in China.…”

“…Visual needs were the visual functions that patients really wanted to improve. Several questionnaires were used in the clinic according to different patients such as Elderly Low Vision Quality of Life Questionnaire (ELVQoL) [17], Low Vision Quality of Life Questionnaire, and Visual Function-25, of which ELVQoL was the most commonly used. Children less than 10 years old were accompanied by guardians and they answered questions together.…”

“…In America, reading, driving, watching movies, sports, and work-related duties were the most important needs of patients with visual impairment [12–16]. However, there is little research addressing the needs for visual improvement of visually impaired patients in China [17]. For a better understanding of the needs of Chinese patients with visual impairment, we did this study.…”

Purpose. To characterize the needs for visual improvement of new-visit patients with low vision.Methods. This cross-sectional study collected detailed information of patients presented at low-vision center of the Eye Hospital of Wenzhou Medical University between January 2015 and January 2017. A questionnaire interview, including demographic information and needs for visual improvement, was conducted before ophthalmology examinations.Results. The main need for visual improvement was engagement in hobbies (68.9%), followed by reading (20.9%), engaging in occupation (20.1%), and watching TV or movies (17.1%). Less than 10% of patients mentioned the demand of using public transportation (5.8%), doing housework (3.7%), writing (1.9%), walking on irregular surfaces (1.5%), driving (1.1%), and others (2.4%). Women were significantly associated with a concern for performing hobbies (OR 1.45, 95% CI 1.0–2.0) but associated with lower odds of reading (OR 0.46, 95% CI 0.3–0.7). Older subjects were more willing to choose hobbies (OR 1.35 (per 10-year increase), 95% CI 1.3–1.4), reading (OR 1.11 (per 10-year increase), 95% CI 1.0–1.2), watching TV or movies (OR 1.4 (per 10-year increase), 95% CI 1.3–1.6), and housework (OR 1.21 (per 10-year increase), 95% CI 1.0–1.5) than younger individuals. In comparison with younger participants, older individuals were less likely to choose occupation (OR 0.53 (per 10-year increase), 95% CI 0.5–0.6). No significant association was found between visual acuity and needs for visual improvement.Conclusion. Hobbies, reading, engaging in occupation, and watching TV were the most common needs for visual rehabilitation in patients with visual impairment. Gender and age showed a modest influence on the choice of different needs.
