<p>The Early Executive Functions Questionnaire (EEFQ) is a 31-item parent-report measure which complements temperament measures by targeting cognitive and regulatory capabilities. Exploratory Factor Analysis with 2 samples of 9-to 30-month-olds (n=486; 304) indicates that Inhibitory Control, Flexibility and Working Memory scales load onto a common ‘Cognitive Executive Function (CEF)’ factor, whilst a fourth scale, Regulation, does not. CEF and Regulation scores show low floor and ceiling effects (&amp;lt;1%), good internal consistency (Cronbach’s alpha &amp;gt;.75), short-term stability (bivariate correlations across 3-6 months &amp;gt;.38), and convergent validity with extant measures of attentional control. Only CEF scores increase with age. With the EEFQ it is now possible to use parent report to measure development of EF skills across infancy and toddlerhood.</p>
