ABSTRACT=<sec><title>Objective</title><p>The objective of this study was to examine the structure of sibling relationships among preschool children in China and develop a questionnaire.</p></sec><sec><title>Methods</title><p>The concept of sibling relationships among preschool children in China was established through literature review, open interviews, and expert review, and the initial project was designed. Using the questionnaire survey method, with 651 mothers of preschool children as the research objects, we performed item analysis, exploratory factor analysis, confirmatory factor analysis, and reliability and validity tests on the initial questionnaire.</p></sec><sec><title>Results</title><p>The questionnaire for the sibling relationships among preschool children in China had 18 questions covering dimensions of sibling interaction, sibling acceptance, sibling warmth, and sibling rivalry. The questionnaire fitting indexes were better (χ<sup>2</sup>/<italic>df</italic> = 1.829, CFI = 0.930, TLI = 0.917, RMSEA = 0.055, SRMR = 0.053). The internal consistency coefficient between the total questionnaire and each dimension was 0.759–0.8548, and the total questionnaire significantly correlated with each dimension (<italic>r</italic> = 0.229–0.792) and the total score of parental self-efficacy (<italic>r</italic> = –0.106 to 0.338).</p></sec><sec><title>Conclusion</title><p>The Sibling Relationship Questionnaire for Chinese Preschool Children (Parental Version) exhibited good reliability and validity, making it an effective tool for the evaluation of sibling relationships among preschool children.</p></sec>
