Revised Mean, SD, and Cutoff Points for Selected ASQ Intervals

Revised means, standard deviations (SD), and cutoff points, shown in the table below, are available for selected ASQ questionnaire intervals. With the exception of the cutoff points for the communication area for 14, 18, and 22 months, the cutoff points shown below were calculated by subtracting 2 SD from the mean. The revised cutoff points appear in the fifth printing of the English ASQ questionnaires and also apply to the ASQ CD-ROM, the Edades y Etapas CD-ROM, and the Spanish and French ASQ questionnaires.
