Sensory overresponsivity: prenatal risk factors and temperamental contributions.

ABSTRACT:

Objective

The study addresses risk factors and cause of pediatric sensory over-responsivity (SOR) in a large sample of twins. At age 2 years, (a) the association of temperamental traits with concurrent SOR; (b) the association of prenatal complications with SOR; (c) the association of having a male cotwin with female SOR; and (d) the common and unique genetic causes of temperament and SOR symptoms are examined.

The sample included 1026 twin pairs (mean age = 2 years 2 months) from a population-based longitudinal study. Auditory and tactile SOR symptom domains were partially independent and thus were examined separately.

Results

Temperamental negative affect and fear were moderately correlated with auditory and tactile SOR symptoms. Prenatal complications signi
