The present case-control study was based on the assumption that mothers of autistic children could show, in relation to the mothers of the general population, more indicators of anxiety and stress with a consistent profile of cortisol production. To test it we used several classic instruments indicative of anxiety and stress (PANAS: Positive And Negative Affect Schedule; BAI: Beck Anxiety Inventory; IDATE: Trait-State Anxiety Inventory; ISSL: Lipp Adult Stress Inventory; ASR: Adult Self-Report) and salivary cortisol dosages before and after acute stress induction tasks (TSST). The results showed that: 1) the stress and anxiety profile was similar in the 2 groups of mothers (cases and controls) under baseline conditions and after stress induction tasks; 2) immediately after the task of induction of stress the 2 groups of mothers showed increase of negative feelings and decrease of positive feelings being that after 20 minutes they recovered the positive feelings with greater effect among the mothers case; 3) the baseline cortisol dosage of the control mothers was higher and the subsequent dosages followed the same pattern as the group cases; 4) cortisol levels differed from those expected in relation to the stress task since the highest levels were reached in the recovery phase; 5) Emotional activation was higher in the control mothers than in the mothers cases, corroborating the higher cortisol dosages in this group; 6) Mothers presented baseline and post-stress cortisol levels lower than controls. 7) Mothers cases and controls have similar socioeconomic conditions, however the aggravating of caring for a child with developmental disorder, produces an extra burden on mothers cases, leading to resilience with less reactivity to situations of acute stress, contributing to a dysfunction of the HHA axis, with decreased levels of salivary cortisol, before and after the task of stress. 8) other variables need to be controlled, and a larger sample number is also required for data validation.
