A scoping review of longitudinal studies of children with vision impairment

Abstract

In past comparative studies, children with vision impairment were often shown a developmental delay compared to sighted children in several developmental domains. Medical treatments of vision impairments and societal attitudes toward disabilities changed considerably. Besides, within the rehabilitation practices, a stronger integration of multiple perspectives and increased focus on social inclusion and participation in society is present. The main goal of this scoping review was to investigate what is known about the development in cognition, language and communication, motor, social–emotional, and adaptive skills development of children with vision impairment by longitudinal studies. Besides, the results of the past studies were related to a contemporary view on disability, the participation concept. This was done by applying the family of participation-related constructs (fPRC) framework to examine which factors were covered and which not. A systematic literature search was performed in Web of Science, PsycInfo, ERIC, and Medline. Studies were included if they have been published in peer-reviewed journals between 1994 and 2020 had a longitudinal design and examined the development of children with vision impairment with no additional impairments up to 18 years of age. From the 2698 identified studies, 32 studies were included. The most commonly assessed variables concerned cognition and language and communication development. To a lesser extent, studies examined adaptive skills, motor, and social–emotional development. The majority used vision status as a predictor variable for developmental outcomes. In terms of the fPRC framework, most studies included variables related to the factor activity competences. The factors preferences, sense of self, environment, and involvement were studied far less often. The review suggested a positive impact on developmental outcomes for including variables that can mediate the relation between vision status and developmental outcomes and variables that are related to the fPRC factors environment, sense of self, and preferences.
