ABSTRACT. The aim of this study was to examine the validity and reliability of the Turkish version of the Solution Focused Inventory (SFI). This inventory was developed by Grant, Cavanagh Kleitman, Spence, Lakota and Yu (2012) and has 12 items and three sub-scales. The sample of the study consists of 176 university students. The linguistic convenience and validity were supported by the positive correlation between the scores of the English and Turkish forms. The correlation coefficients were .92 for Problem disengagement sub-scale, .94 for Goal-orientation sub-scale, .91 for Resource Activation. This inventory's Confirmatory Factor Analysis (CFA) results were RMSEA= .072 CFI= .94, IFI= .94, TLI=.91, GFI=.93, AGFI=.87. Key Words: solution focused thinking, inventory, reliability, validity SUMMARY Purpose and significance: This study aims to adapt a solution focused inventory for assessing the solution focused change. Solution Focused Inventory is an instrument which is designed to fill the gap in a reliable and functional instrument for solution focused approaches.
