CONCLUSION Our models show that subjects with higher SDMT scores at baseline showed improvement, while subjects with lower SDMT scores at baseline showed worsening. Baseline age and disease duration were also associated with SDMT performance.Objective The study objectives were (1) to create a new 10-item scale, the 'Lebanese Anxiety Scale' (LAS-10), inspired by the diagnostic criteria of DSM-5, and the HAM-A and STAI scales and (2) to evaluate the performance of this new scale on a sample of Lebanese individuals.Methods This cross-sectional study enrolled 1332 community dwelling participants between November 2017 and March 2018.Results In sample 1, the participants' mean age was 28.08 years (63.9% females). The LAS items converged over a solution of two factors that had an Eigenvalue over 1, explaining a total of 51.97% of the variance (αCronbach=0.857). The optimal cut-off between healthy controls and anxious patients was 13.50 according to the ROC curve. The sensitivity and specificity were good at this cut-off (77.5% and 70.8%, respectively). The area under the curve was high 0.811 [0.778-0.845]; p  less then  .001. The positive predicted value of the LAS-10 score in sample 1 was 26.9%, whereas the negative predicted value was 95.2%.Conclusion The results of the present study show that the LAS-10 is a tool that can be used in clinical practice and research to screen for anxiety.KEY POINTSThe positive predicted value of the LAS-10 score was 26.9%.Its negative predicted value was 95.2%.People with scores above 13.5 be referred to a health care professional for further assessment.The LAS-10 is a tool can be used in clinical practice and research to screen for anxiety.Future studies are needed to validate the LAS-10 in other countries.A prodrome is considered an early set of signs or symptoms indicating the onset of a disease or illne
