The aim of the current study was to adapt the Early Prosocial Behavior Questionnaire developed by Giner Torréns and Kärtner (2017) to Turkish and to evaluate its validity and reliability. The sample included a total of 267 mothers of 18-36 months children. The participants completed Demographic Form, Early Prosocial Behavior Questionnaire, The Strengths and Difficulties Questionnaire (SDQ). Exploratory and confirmatory factor analysis supported three factors structure representing helping, sharing and comforting. Results also showed that relationships between the subscales (helping, sharing and comforting) and the child's psychosocial development were significant in the expected directions; criterion-related validity of the scale was supported. There was no difference according to gender of child, education and income level of mother and the method of collecting the data (online survey system or communication directly). The subscales had acceptable levels of internal consistency and test-retest reliability. The findings revealed that Turkish Early Prosocial Behavior Questionnaire was a valid and reliable measure for children between 18-36 months. The results were discussed with the suggestions to improve the scale.
