Fig 6. Serial multiple mediational model for the relation between an interoceptive sensibility (autonomic reactivity) and somatoform disorders, where alexithymia and difficulties in emotion regulation constitute mediators.

(c) A direct effect of the impact of interoceptive sensibility on the somatoform disorders. (a1, b1) An indirect effect of the impact of interoceptive sensibility on the somatoform disorders, including alexithymia. (a2, b2) An indirect effect of the impact of interoceptive sensibility on the somatoform disorders, including Difficulties in Emotion Regulation. (a1, d21, b2) An indirect effect of the impact of interoceptive sensibility on the somatoform disorders, including Alexithymia and Difficulties in Emotion Regulation. (c`) A direct effect of the impact of interoceptive sensibility on the somatoform disorders, taking account of the impact of both mediators. *-p<0,05; **-p<0,01. Interoceptive sensibility (autonomic reactivity) was measured by Body Perception Questionnaire-Short Form (BPQ-SF). Somatoform disorders was measured by Somatoform Dissociation Questionnaire (SDQ-20). Difficulty in regulation emotion was measured by Difficulties in Emotion Regulation Scale (DERS). Alexithymia was measured by The Toronto Alexithymia Scale– 20 (TAS-20).
