The purpose of this study was to assess the validity and reliability of Relationship Deciding Scale (Vennum & Fincham, 2011) for Turkish culture.,The sample of the study consisted of 880 students EFA= 439, CFA=441) studying at Karadeniz Technical University. Criterion-related validity, exploratory and confirmatory factor analyses were conducted for the validity of RDS while internal consistency, split half and test-retest techniques were performed to examine the reliability of RDS.,Exploratory factor analysis (EFA) revealed that the scale had two-factor structures. However, two items were removed from the scale because they didn't have appropriate factor loadings. The scale consisting of 10 items explained 58.97% of the total variance. The results of confirmatory factor analysis (CFA) indicated that the model was compatible with the data. In the reliability analysis for EFA and CFA samples, Cronbach alpha coefficients were found as .87 and .86 respectively. Internal consistency coefficients of subscales were found as .83 and.80 for "Relationship Confidence",.82 and .84 for "Directing Relationship". According to test-retest reliability analysis results, the whole scale's coefficient was r=.67. In addition, as a result of criterion validity analysis, correlations r=.33) between Self-Control Scale (Duyan, Gulden & Gelbal, 2012) and Relationship Deciding Scale RDS) were found to be statistically significant. In conclusion, these findings suggest that RDS, which has two-factor structures with 10 items, can be suggested as a valid and reliable instrument in Turkish culture.
