The purpose of this study was to investigate the validity and reliability the episodic foresight test. This study is a descriptive- analytic one. The statistical population of this study was all children ages 3, 4 and 5 with low executive functions in kindergartens in Ahvaz city on 1397. In this study 60 children was selected by random sampling method, and responded to episodic foresight test (Atance & Meltzoff, 2005). To examine of the reliability of the instrument, the reliability indicator of the evaluators and the Kappa method and the Cronbach's alpha coefficient were used and, to determined the validity of the instrument, one-way analysis variance and binomial test were used. The result of the research showed that correlation between evaluators in scoring non-verbal section was 1.00 and in scoring verbal section was 0.99, and the Kappa correlation coefficient between the evaluators for each scenario was among 0.94 to 1.00, and cronbach's alpha coefficient was 0.75. To examine the validity of the instrument, the result of the binomial test showed that the children correct response rate was significantly higher than the response rate by chance. Also, the results of analysis of variance showed that there is a significant difference between children means score based on age and the Scheffe test showed that 3 years old children achieved scores lower than 4 and 5 years old children. But, there is no significant difference between scores of 4 and 5 years old children.
