Abstract(s)

Aim: The present study intends to evaluate the factorial validity and reliability of a reduced version of the Derriford Appearance Scale (DAS-14) for the Portuguese population. Method: After analysis of six samples collected between 2010 and 2017, a total of 1016 participant answered questions related to the schematic investment of appearance and self-consciousness of appearance (DAS-24), authorization was requested to the authors of the original and Portuguese version of the DAS-24 to reduce the scale to 14 items. Results: The DAS-14 presented good internal consistency to non-clinical sample (Cronbach's alpha = 0.91) and (Cronbach's alpha = 0.88) to clinical samples. The Confirmatory Factor Analysis of the DAS-14, presents an acceptable to non-clinical sample (chi(2)/gl = 1.17; GFI = 0.95; CFI = 0.99; TLI = 0.98; RMSEA = 0.028; p[rmsea <= .05] = 0.92), and clinical sample (chi(2)/gl = 1.36; GFI = 0.94; CFI = 0.98; TLI = 0.96; RMSEA = 0.047; p[rmsea <= .05] = 0.56). Conclusion: The Portuguese version of the DAS-14 is psychometrically robust in evaluating self-consciousness of appearance in general and clinical population.
