Abstract

Introduction: The aim of the research was to develop a developmental assessment scale of developmental abilities in the fields of cognition and literacy, an approach to learning, physical-motor, social-behavioral-emotional in children 1-2 years old and to investigate the psychometric characteristics of the list in children 1-2 years old in Tehran.
Methods: The statistical population included all children aged 1-2 and their parents in Tehran. The sample size included 500 children aged 1-2 years; 100 children were considered for each area. The data collection tool is a researcher-made tool that uses the developmental standards of several American states, such as the developmental standards of Washington (2012), the developmental standards of Nebraska (2018), and studies conducted in Iran.
Findings: The results showed that the difficulty coefficient shows the moderate to high ease of the questions. Also, the findings show that there is a positive and significant relationship between the cognition scale and the subscales of logic, arithmetic, science and studies, between the physical-motor scale and the subscales of gross motor skills and motor skills, the language and literacy scale with the subscales of perceptive or receptive language. Expressive language, reading and writing, and between the emotional-behavioral-social scale with the subscales of self-concept, self-regulation and other scales, which shows the construct validity of the scale (of internal consistency).
Conclusion: The results of alpha coefficient and retest indicated the reliability or validity of the scale; Therefore, according to the appropriate psychometric properties, this scale can be used in research.
