Motor Development Scales Validated in Spanish Populations of Children Aged 0–18 Months: Systematic Review

Background/Objectives: The assessment of motor development in early ages is considered fundamental for the early identification of alarm signs that indicate the possibility of a child suffering from a developmental disorder. To this end, it is necessary to use reliable evaluation tools that have been specifically validated in the target population. The main aim of the current review was to examine the existing motor development assessment tools validated in Spanish populations of children aged 0–18 months. Methods: A systematic review was carried out following the PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analyses) declaration criteria, and it was registered in PROSPERO. A bibliographic search was conducted in the PubMed, Scopus, Web of Science, and Cochrane databases, using terms related to motor development, assessment tools, and validation. The COSMIN verification list was employed to evaluate the quality of the included scales, and the QUADAS-2 instrument was used to analyse the quality of the included studies. Results: A total of 7 studies were included in the review, all of which were validation studies of motor development assessment tools in Spanish populations of children aged 0–18 months. Moreover, they all show heterogeneity with respect to their characteristics, such as target population, sample size, and metric properties. Conclusions: The present systematic review provides relevant information about the characteristics and methodological quality of motor development assessment tools validated in Spanish populations. There are currently very few of these evaluation tools, as well as limitations in regard to theories that support them, their metric properties, and the methodological quality of their validation studies. Therefore, we confirm the need for validating updated motor development tools to improve the detection, prognosis, and evaluation of children with developmental disorders or at risk of suffering from them.
