Fig 4. The model of mediation for the tendency toward alexithymia between the impact of interoceptive sensibility (autonomic reactivity) on the level of somatoform disorders.

*-p<0,05; Significant mediation relation are marked in bold. Direct effect–X on Y without the influence of M1 –c. Indirect effect of X on Y through M—a1,b1; a2,b2; a3,b3. Direct effect–X on Y including the influence of M–c`1;c`2;c`3. Interoceptive sensibility (autonomic reactivity) was measured by Body Perception Questionnaire-Short Form (BPQ-SF). Somatoform disorders was measured by Somatoform Dissociation Questionnaire (SDQ-20). Alexithymia was measured by The Toronto Alexithymia Scale– 20 (TAS-20).
