In this study, it is aimed to develop a scale for assessing children's ability to say "no". The participants included in the study are the area experts that helped to achieve content validity, and fourth graders who are asked to score the items in the SN to have an idea about the construct validity, measurement reliability and item discrimination of the item in the scale. In this study, four different drafts of the SN which contained 24 items of 3-pointed Likert type, 22 items of 3-pointed Likert type, 12 items of 3-pointed Likert type and 12 items of 5-pointed Likert type were used. In order to evaluate the content validity of the SN, the experts' opinions were received. For the construct validity, exploratory and confirmatory factor analyses were conducted. Reliability of measurements obtained with the SN was analyzed by using the methods of Cronbach's Alpha and Split-half. An opinion was formed about the distinctiveness of items in the scale setting out from the corrected item total correlations ( CITC) and the results of the independent samples t-tests. The results of the study showed that the SN can be used as a data collection tool, and is able to produce valid and reliable interpretations in studies that aim to explore children's ability to say "no".
