PURPOSE: To evaluate the psychometric properties of the Chinese version of the Near Activity Visual Questionnaire (NAVQ).
SETTING: The Eye Hospital of Wenzhou Medical University.
DESIGN: Randomized single-center observational study.
METHODS: The original English version of the NAVQ was translated and crossculturally adapted into Mandarin. Participants with presbyopia completed the NAVQ. Clinical data, including monocular and binocular habitual near visual acuity (HNVA), manifest refraction spherical power, cylindrical power, and near addition (ADD), were collected. The NAVQ was psychometrically assessed using Rasch analysis metrics. The criterion validity was evaluated by correlating the Rasch score with clinical data.
RESULTS: 175 participants with presbyopia (median age: 65 years, female: 42.9%) were included. Rasch analysis demonstrated that the NAVQ was unidimensional, with ordered thresholds, good measurement precision (person separation measure: 2.86), and acceptable targeting (0.99 logit). The NAVQ Rasch score correlated strongly with binocular HNVA ( rs = 0.678) compared with better-eye and worse-eye visual acuities. It also showed moderate correlations with additional power ( rs = 0.523) and the spherical equivalent for presbyopia correction in the better eye ( rs = 0.656) and worse eye ( rs = 0.647) (all P < 0.001).
CONCLUSIONS: The Chinese version of the NAVQ demonstrated good psychometric properties and validity in a Chinese presbyopia population.
