Özet:

The aim of this research was to adapt the Mental State Conceptual Learning Inventory (MSCLI) developed by Liu, Hou, Chiu and Treagust (2014) into Turkish and to conduct validity and reliability studies.  The original language of the inventory is English and it consists of 40 items. For the adaptation study, the inventory was translated into Turkish and linguistic equivalence was provided.  Opinions of experts were obtained for content validity and the study was conducted with 862 high school students. Confirmatory Factor Analysis was used to provide the construct validity and it was determined that the most satisfactory goodness of fit indices was obtained by the model which is consisting of 30 items and four sub-dimensions [χ2(397, n= 862) = 1902.75, p<.000, RMSEA= 0.066, GFI= 0. 87, CFI = 0.94, NNFI = 0.94, χ2/sd≤5. Factor loadings of the items were statistically significant and ranged from .30 to .84. The Cronbach's α reliability coefficient was calculated as .841 for emotion sub-dimension; .788 for intention sub-dimension; .703 for internal mental representation sub-dimension; .813 for external mental representation sub-dimension and .899 for the inventory. As a result, it could be stated that the Turkish form of the Mental State Conceptual Learning Inventory is a valid and reliable scale.
