The Italian adaptation and validation of the Adult Sibling Relationship Questionnaire (ASRQ) in Italian emerging adults

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 individuals’ current perceptions of their own behaviour and feelings toward their sibling, as well as their perceptions of their sibling’s behaviour and feelings toward him or her by assessing fourteen fundamental dimensions (Intimacy; Affection; Emotional Support; Instrumental Support; Knowledge; Similarity; Admiration; Acceptance; Dominance; Competition; Antagonism; Quarrelling; 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 central Italy. Confirmatory factor analyses showed a factorial structure with fourteen first-order factors and two second-order factors. The internal consistency coefficients () were satisfactory for each of the 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.
