The conversion and reliability tests of Self Concept Scale which was developed by E. V. Piers and D. Harris, and which consisted of 80 items, was conducted between 1986-1987, besides its confirmed validity in the test of reliability the correlation coefficient of internal consistency was found to be between 78 and 93. The Family Evaluation Scale consisting of 7 sub-test and a total of 60 test items was developed from Mc Master's Family Functions Model and it was adapted by Işıl Bulut in 1990.
