Background A new measure of self‐determination, the Self‐Determination Inventory: Student Report (Spanish version), has recently been adapted and empirically validated in Spanish language. As it is the first instrument intended to measure self‐determination in youth with and without disabilities, there is a need to further explore and strengthen its psychometric analysis based on item response patterns. Method Through item response theory approach, this study examined item observed distributions across the essential characteristics of self‐determination. Results The results demonstrated satisfactory to excellent item functioning patterns across characteristics, particularly within agentic action domains. Increased variability across items was also found within action‐control beliefs dimensions, specifically within the self‐realisation subdomain. Conclusions These findings further support the instrument's psychometric properties and outline future research directions.
