Current study builds and validates the Invulnerability Perception Scale (IPS). Items were formulated according to theoretical proposals already established in international literature. Fifty-eight items were prepared and submitted to referees' criteria for semantic validation. Factorial validation was forwarded by 350 applied questionnaires which contained the instrument's pilot version. Principal components analysis and PAF (Principal Axis Factoring), with orthogonal rotation, were employed in the process. Results show three factors with suitable psychometric properties ranging from good reliability indexes to semantic consistency consonant with the theoretical approach. This fact validates the scale's good internal consistency. The final version contains 14 items distributed among three factors. Application possibilities and research's limitations are also discussed.
