Adult sibling relationship questionnaire - A tool for the recording of sibling relationships in adulthood

This paper presents testing results, as well as the German translation of the "Adult Sibling Relationship Questionnaire" ("ASRQ"), a self-report measure that can be used to raise information on adult sibling relationships. The "ASRQ" consists of 81 items spread over 14 scales. The questionnaire assesses qualitative features of sibling relationships in young adulthood and beyond. The items on the 14 scales are combined to form 3 higher-order factors: "Warmth", "Conflict" and "Rivalry". Results of a sample of adults (N=388) confirms that the German version of the "ASRQ" can be very well used as an objective and reliable self-report measure. The analysis of psychometric data confirms early research results on the one hand and point to the necessity of additional research on sibling relations in adulthood on the other hand.
