The current study developed and validated the Creativity Nurturing Behavior Scale (CNBS) to assess sibling interactions that foster creativity. It is specifically designed to capture the unique relational behaviors within a sibling dyad. The scale was grounded in theories of social learning, attachment, and creative cognition. A rigorous psychometric analysis, including exploratory and confirmatory factor analysis, demonstrated the scale's reliability and validity with a 32-item and eight-factor structure. Measurement variance across genders was established. Latent mean comparisons revealed significant gender differences in certain dimensions of sibling relationships. The scale's reliability and validity were established using a sample primarily consisting of multi-child, traditional family structures from India and Oman. The CNBS offers a tool for researchers to understand creativity development within this specific sibling dynamic of high family salience households. The scale showed a significant correlation with creativity performance. The CNBS provides a valuable tool for researchers and practitioners to understand and promote creativity development within the sibling dynamic of high family salience households. A key limitation of the CNBS is its current validated scope, which is not generalizable to single-child families, highly diverse family structures, or different macro-cultural contexts without further re-validation.
