Results showed acceptance is correlated strongly with almost all depression symptoms and all of anxiety symptoms (P>0.01); Moreover mindfulness were correlated moderatly with some of depression and two anxiety symptoms (P>0.01); finally anxiety sensitivity was moderately correlated with some depression and strongly with anxiety symptoms (P>0.01). Regression analysis revealed experiential avoidance has significant role in depression symptoms like Lassitude, Insomnia, Suicidality, Appetite gain, Ill Temper and Well-being, but mindfulness and anxiety sensitivity have weaker role in some symptoms of depression (P>0.01). Also results showed anxiety sensitivity has a dominate role, but experiential avoidance moderate and mindfulness a weak role in anxiety symptoms (P>0.01). Experiential avoidance can be seen as a dominant and common transdiagnostic process in emotional disorders, but anxiety sensitivity is just more influencing process in anxiety symptoms of emotional disorder and mindfulness is a weak transdiagnostic process in emotional disorders.
