Psychometric analysis of the Greek version of the Sibling Relationship Questionnaire

Abstract

Siblings’ relationships are determinants of emotional and personal development. Although Greece is assumed a country with strong family bonds, no empirical research in this area exists; one of the reasons being the lack of reliable instruments. The SRQ is a widely used scale to measure this relationship. The aim of the present study was to translateand examine the psychometric properties of SRQ. One hundred and eighty five children and adolescents were recruited. Concurrent validity, internal consistency, test-retest reliability and agreement between parents-children versions of the translated scale were investigated. Concurrent validity ranged from 0.29 to 0.68, the overall internal consistency was 0.86 and the test-retest reliability ranged from 0.58 to 0.78. Agreement between children-parents versions was significant only when mothers do the rating. Confirmatory factor analysis for the two important dimensions Warmth/Closeness and Conflict, which have been identified in the original study it shows that they are also present also in the Greek version. Thus, the Greek version of SRQ is a valid and reliable instrument to be used within the Greek population, for multinational clinical research and for comparison with findings from other countries.
