The Italian adaptation and validation of the Sibling Relationship Questionnaire (ASRQ)

The aims of the present study were to provide a contribution to the validation of the Adult Sibling Relationship Questionnaire (ASRQ; Stocker, Lanthier & Furman, 1997) with a population of Italian emerging adults. The ASRQ measures individual's current perceptions of their own behavior and feelings toward their siblings, as well as their perceptions of their sibling's behavior and feelings toward him/her by assessing 14 fundamental dimensions (intimacy; affection, emotional support; instrumental support; knowledge; similarity; admiration; acceptance; dominance; competition; antagonism; quarreling; maternal rivalry; and paternal rivalry), combined in order to form three macro-dimensions: Warmth, Conflict, and Rivalry. The sample comprised 464 young adults (200 males and 264 females), aged from 18 to 28 years, living in the central Italy. Confirmatory factor analyses showed a factorial structure with fourteen first-order factors and two second-order factors. The internal consistency were satisfactory each of fourteen ASRQ dimensions and the ASRQ macro-dimensions. Further, the present study provided support for the convergent validity of the ASRQ, also within the Italian context.
