Turkish Adaptation of Relationship Quality Scale: Validity and Reliability Study

Objective: The purpose of this study is to adapt to psychometric properties of the Relationship Quality Scale which was developed to evaluate the individual's perception of relationship quality in the current relationship, to Turkish culture. Method: Validity and reliability analyses were analyzed with 371 participants (62.8% female, 37.2% male). Demographic Information Form, Relationship Quality Scale and The Relationship Assessment Scale were used as data collection tools. After the linguistic equivalence analysis of the scale, the validity analysis was started. Validity analyses were tested with construct and convergent validity. Confirmatory Factor Analysis (CFA) was utilized in the construct validity process. The Relationship Assessment Scale was used to convergent validity. Reliability analyses of the Relationship Quality Scale were evaluated with Cronbach's Alpha internal consistency coefficient and test-retest methods. Results: The CFA results were found to be χ2 value 71.31, χ2 /df= 2.85, RMSEA= 0.071, GFI= 0.96, CFI=0.99, NFI=0.99, AGFI= 0.93 and SRMR= 0.021 at 25 degrees of freedom. The factor loadings of the items were found to be between .63 and .89. CFA validated the unidimensional and 9-item structure of the Relationship Quality Scale. A positive and highly significant relationship was found between the Relationship Quality Scale and the Relationship Assessment Scale at the level of .89. The Cronbach's alpha coefficient was determined as .93. The test-retest reliability analysis result was 0.95. Conclusion: The Relationship Quality Scale has psychometric properties at a level that can measure the relationship quality status of individuals regarding their current relationships and can be used in the relevant literature.
