Individuals with Autism Spectrum Disorder without intellectual disabilities (High Functioning ASD, HF-ASD) present atypical sensory sensitivity, due to the hyper-reactivity to sensory inputs.

To retrospectively evaluate the sensory sensitivity in a sample of mothers with HF-ASD during pregnancy (pre-partum), delivery and childbirth (peri-partum) and during the three months after delivery (post-partum).

19 HF-ASD and 13 neurotypical (NT) mothers were asked to complete an ad-hoc questionnaire designed for the study, named Maternity Questionnaire, assessing sensory perception during pre-, peri- and post-partum. Moreover, they underwent the following assessment: the Autism-Spectrum Quotient (AQ), the Empathy Quotient (EQ), the Ritvo Autism Asperger Diagnostic Scale-Revised (RAADS-R), the Edinburg Postnatal Depression Scale (EPSD), the Sensory Perception Quotient (SPQ) and the Post Partum Bonding Questionnaire (PBQ).

At the Maternity Questionnaire, HF-ASD mothers showed higher sensitivity scores than NT mothers overall. Moreover, HF-ASD mothers presented lower sensitivity during the peri-partum, compared to pre- and post- partum periods, while NT mothers showed a linear decrease from pre- to post- partum. The two groups significantly differed at the AQ, the EQ, the RAADS-R, the SPQ and Factor 3 of the PBQ. Sensitivity during pre- and post-partum positively correlated with EPDS scores.

Mothers with HFA tend to experience pregnancy, childbirth and the post-partum period differently from neurotypical mothers, particularly in terms of hypersensitivity, although during the peri-partum the hypersensitivity decreases. Further studies investigating these aspects might give fundamental hints to provide proper help to HF-ASD mothers during pregnancy and motherhood overall.
