<p>Dear Editor,</p>
<p>On behalf of all authors, I am sending the manuscript entitled “PSYCHOMETRIC PROPERTIES AND LONGITUDINAL MEAUREMENT INVARIANCE OF THE BRAZILIAN VERSION OF THE SUBJECTIVE HAPPINESS SCALE”, to your appreciation and to editorial analysis of Revista Interamerica de Pscicologia , as to the possibility of its publication.&nbsp; The manuscript assessed the psychometric properties of the Subjective Happiness Scale in Brazilian adolescents. As the main result, we found that Brazilian version of Subjective Happiness Scale showed adequate validation properties to be used in a population of adolescents. These findings are important for studies that evaluate happiness and oral disorders. And, implementation of decisions of public policies can be carried out from the subjective and normative knowledge of the health conditions in a specific population.</p>
