The MBSEincludes ten steps. For validity studies, face validity, content validity, and construct validity (exploratory factor analysis) were done. For reliabilitystudy, Kuder Richardson was calculated.Results: The content validity index was found to be 0.94. Kendall W coefficient was 0.80 (p=0.551). The total variance explained by the two factorswas found to be 63.24%. Kuder Richardson 21 was done for reliability study and found to be 0.97 for the instrument. The final instrumentincluded 10 steps and two stages.Conclusions: The Turkish version of MBSE is a valid and reliable instrument for early diagnose. The MBSE can be used in Turkish speakingcountries and cultures with two stages and 10 steps.
