In the cases of Social Anxiety Disorder (SAD), treatment dropout is a frequent problem, which demands the development of instruments that enable treatment compliance. The present paper deals with the construction and validation of the Social Anxiety Disorder Exposure and Evaluation Scale (SADEE). The number of participants in the study was N = 407 responders of both genders. The process of content validity first led to the modification of problematic items. The construct validity was investigated by both exploratory factor analysis and confirmatory factor analysis, with the objective of estimating a unidimensional measure. The final adjustment obtained was that CFI = .99; TLI = .98; RMSEA = .04; SRMR = .07; χ2 /gl = 1.70. SADEE presented high correlation with the Liebowitz Social Anxiety Scale and high reliability. The conclusion was that SADEE showed satisfactory evidence of construct and concurrent validity, internal consistency and test-retest reliability.
