The essential aim of this study was to constitute a ‘Tolerance Tendency Scale Form for Adults’ so as to specify individuals’ level of tolerance tendency. At the outset, a Likert-type pre-form in accordance with the 30 items within the item pool was composed. In this research which comprised three distinct groups of participants, 515 individuals constitute the first group who will go through the exploratory factor analysis evaluation, 498 individuals went through the confirmatory factor analysis evaluation, and 126 individuals were incorporated within the test-retest reliability analysis phase. In other words, 1139 individuals were totally involved in this study as participants. The result of the exploratory factor analysis which was generated by means of the data obtained from the first group of participants, a two-dimensional structure under the names of ‘respect for differences’ and ‘acceptance’ which were composed of ten items specifying 55.53 % of the total variance of the scale was obtained. So as to verify this structure, it was conceived that the compliance values of the model were convenient and that they fulfilled the criteria values at a significant level in the wake of the confirmatory factor analysis by means of the data obtained from the second study group. With the results of the test-retest, reliability analysis generated by means of the data obtained from the third group of participants so as to clarify the reliability of the scale, it was designated that the coefficient value for ‘respect for differences’ was 78, for ‘acceptance’ 77 and for the total scale 84. In addition to this, as a result of the alternative reliability studies, it was ascertained that the scale and its sub-aspects had revealed reliable outcomes. As a conclusion, it could be identified that this scale which was constituted in the wake of the whole process is a reliable and valid instrument.
