Brief summary

This observational methodology study will produce a Turkish version of the Nottwil Environmental Factors Inventory (NEFI-TR) within one month using a standardized translation and cultural adaptation process. Content validity will be assessed using an expert panel (and, if applicable, cognitive debriefing with adults with spinal cord injury) to ensure relevance, clarity, and comprehensibility of each item in the Turkish context.

Detailed description

Translation/adaptation: (1) two independent forward translations into Turkish; (2) reconciliation and harmonization by a multidisciplinary committee; (3) back-translation by independent translators; (4) expert committee review for semantic, idiomatic, experiential, and conceptual equivalence; (5) pre-test/cognitive debriefing (if planned) and final revisions; (6) proofreading and finalization of NEFI-TR and documentation of all decisions.
