Early developmental assessment with a short screening test, the STEP, predicts one-year outcomes.

ABSTRACT:

Objective

To evaluate the Specific Test of Early Infant Motor Performance (STEP), a rapid screening test of preterm infants at risk for developmental delay.

Study design

We prospectively studied 23 preterm infants' performance on the STEP and the Test of Infant Motor Performance (TIMP) at term and 3 months, and on the Bayley-III at 12 months. We investigated the psychometric qualities of the STEP and determined STEP cutoff scores for low and high-performing infants.

Results

STEP scores at term and 3 months strongly correlate with 12-month Bayley-III gross motor and cognitive scaled scores, while TIMP scores did not. The STEP showed excellent reliability and required 6-10?min to administer.

Conclusion

STEP is a short, easy to administer, early developmental assessment with unique scoring that emphasizes qualitative and quantitative aspects of muscle tone in movements and predicts 12-month Bayley gross motor and cognitive scaled scores.

Project description:ObjectiveFew data about the development of infants born to women with bipolar disorder have been published. We hypothesized that infants of women with bipolar disorder (by DSM-IV criteria) treated with psychotropics (BD+) or untreated with psychotropics (BD-) would demonstrate poorer cognitive and behavioral development than infants of controls. On the basis of previous studies, we expected that psychotropic-exposed infants of women in the BD+ group would have poorer neuromotor performance during infancy.MethodsThis longitudinal study included 197 mother-infant dyads recruited to participate between July 2006 and March 2011: 81 with prenatal maternal bipolar disorder without psychotropic treatment (BD-, n = 27) or bipolar disorder with psychotropic exposure (BD+, n = 54) and 116 in which infants were exposed to neither bipolar disorder nor psychotropics. Maternal psychopathology and pharmacotherapy exposure assessments were completed at 20, 30, and 36 prenatal weeks and 12, 26, and 52 weeks postpartum. Infants were evaluated with the Bayley Scales of Infant Development, Second Edition, which included the psychomotor (Psychomotor Development Index [PDI]), cognitive (Mental Development Index [MDI]), and behavioral (Behavioral Rating Scale [BRS]) components.ResultsNeither prenatal exposure to BD- or BD+ significantly impacted overall PDI (P = .2449), MDI (P = .7886), or BRS (P = .6072) scores. However, we observed a significant effect of BD+ exposure-by-time interaction for the BRS Motor Quality index (F₂₄₅ = 3.16, P = .0441), with BD+ exposed infants less likely to be above the 75th percentile at the 52-week assessment (mean = 11.5%) compared with BD- (mean = 40.0%) and nonexposed infants (mean = 48.4%).ConclusionsWe found no significant impact of prenatal BD- or BD+ exposure on infant PDI, MDI, or overall BRS scores at 12, 26, or 52 weeks of age, with most scores remaining within normal limits. Consistent with previous studies, we found a specific effect of prenatal BD+ exposure on quality of motor functioning at 1 year. However, the majority of infants were within normal limits on this developmental outcome.Trial registrationClinicalTrials.gov identifier: NCT00585702.
