It consists of five domains: movement variation, variability, fluency, symmetry, and performance. The aim of this study was to assess interobserver reliability and concurrent validity of the <jats:styled-content style="fixed-case">IMP</jats:styled-content> with the <jats:styled-content style="fixed-case">A</jats:styled-content>lberta <jats:styled-content style="fixed-case">I</jats:styled-content>nfant <jats:styled-content style="fixed-case">M</jats:styled-content>otor <jats:styled-content style="fixed-case">S</jats:styled-content>cale (<jats:styled-content style="fixed-case">AIMS</jats:styled-content>) and an age‐specific neurological examination.</jats:p></jats:sec><jats:sec><jats:title>Method</jats:title><jats:p>Fifty‐nine preterm infants (25 females, 34 males; median gestational age 29.7wks, median birthweight 1285g) and 146 term infants (74 females, 72 males; median gestational age 40.1wks, birthweight 3500g) were included. Assessments were performed at corrected ages of 4, 6, 10, 12, and 18 months and consisted of the <jats:styled-content style="fixed-case">IMP</jats:styled-content>,<jats:styled-content style="fixed-case"> AIMS</jats:styled-content>, and an age‐specific neurological examination. Interobserver reliability was investigated on a sample of 25 video recordings. Non‐parametric statistics were used to analyse the data.</jats:p></jats:sec><jats:sec><jats:title>Results</jats:title><jats:p>Interobserver reliability was high (intraclass correlation coefficient 0.95). At all ages, <jats:styled-content style="fixed-case">AIMS</jats:styled-content> scores correlated weakly to fairly with total <jats:styled-content style="fixed-case">IMP</jats:styled-content> scores (Spearman's <jats:italic>ρ</jats:italic> 0.36–0.55), but moderately to strongly with scores on the performance domain of the <jats:styled-content style="fixed-case">IMP</jats:styled-content> (Spearman's <jats:italic>ρ</jats:italic> 0.47–0.84). A clear relation was found between total <jats:styled-content style="fixed-case">IMP</jats:styled-content> score and outcome of the neurological examination (Kruskal–Wallis <jats:italic>p</jats:italic>&lt;0.001 at all ages).</jats:p></jats:sec><jats:sec><jats:title>Interpretation</jats:title><jats:p>Interobserver reliability of the <jats:styled-content style="fixed-case">IMP</jats:styled-content> is good.
