Spanish Validation of the Parental Expectations and Perceptions of Children's Sibling Relationships Questionnaire

Objective To translate and culturally adapt the Parental Expectations and Perceptions of Children's Sibling Relationship Questionnaire (PEPC-SRQ; Kramer & Baron, 1995) into Spanish and test its psychometric properties. Background Sibling relationships contribute significantly to child development; however, to date, no study has validated an instrument to assess the quality of children's sibling relationships with Spanish samples. Method We conducted two studies. In Study 1, the instrument underwent translation and back-translation along with the inspection of semantic, linguistic, and contextual equivalence. In Study 2, the validity of the instrument scores was assessed by administering the translated PEPC-SRQ to 229 mothers in Spain. Results The Exploratory Factor Analysis revealed a two-factor structure that preserved the original 24 items. Both factors presented good internal consistency and were significantly correlated with other constructs. Conclusion These results support the use of the PEPC-SRQ in Spain. Implications The Spanish PEPC-SRQ may now be used as a tool for the early detection of conflictual relationships between siblings and as a tool for assessing the effectiveness of targeted strategies designed to bolster children's sibling relationships. Additionally, this adaptation provides the opportunity to carry out cross-cultural studies.
