The aim of this study is to examine the psychometric properties of the Turkish adaptation of the Morningness/Eveningness Scale (M/E Scale-Parent Report Form) family evaluation form for preschool children. The study sample consisted of 276 parents with children aged 4-6 years. The study calculated Cronbach's alpha internal consistency coefficient and corrected item-total correlations of the scale. It also determined the scale's distinctiveness, stability analyses, and convergent validity. The Turkish version of the M/E Scale (Parent Report Form), consisting of 10 items, is unidimensional. The Cronbach's alpha internal consistency coefficient of the scale was 0.80 and the corrected item-total correlation values varied between 0.51 and 0.76. There was a positive correlation at the level of 0.75 between the applications of the scale with two-week intervals and at the level of 0.63 between the single-item chronotype scale within the scope of convergent validity and the M/E Scale (Parent Report Form). This study determined a low correlation between the child's chronotype and the father's chronotype, and a moderate correlation with the mother's chronotype. The Turkish M/E Scale (Parent Report Form) was found to be valid and reliable. This scale is a short and easy-to-use measurement tool for determining the chronotypes of 4-6-year-old children.
